Description
【0001】[0001]
各種の異常を検出する無電圧接点及びDC有電圧等の警報入力接点を接続し、 その警報入力接点の入力によって異常を表示及び鳴動等で報知する警報装置に関 する。 The present invention relates to an alarm device in which a non-voltage contact for detecting various abnormalities and an alarm input contact such as DC voltage are connected and the abnormality is displayed and sounded by the input of the alarm input contact.
【0002】[0002]
従来、警報装置は主に図3のように電源電圧Vを常時供給し、異常を検出した 際に無電圧a接点21を入力する警報装置22と、異常を検出した際にニッケル カドミウム電池23のDC6Vの有電圧を入力すると共に、入力されたDC6V を電源電圧とする警報装置24との2種類のものがあり、通常、警報装置は無電 圧a接点21を入力接続する警報装置22と、ニッケルカミニウム電池23のD C6Vの有電圧を入力接続する警報装置24との2種類を同時に用いていた。 Conventionally, an alarm device mainly supplies a power supply voltage V constantly as shown in FIG. 3 and inputs an unvoltage a contact 21 when an abnormality is detected, and a nickel-cadmium battery 23 when an abnormality is detected. There are two types: an alarm device 24 that inputs a voltage of DC6V and uses the input DC6V as a power supply voltage. Usually, the alarm device is an alarm device 22 that inputs and connects a non-voltage a contact 21, and a nickel device. Two types of the alarm device 24 which inputs and connects the voltage of DC6V of the cadmium battery 23 were used simultaneously.
【0003】 例えば、高圧閉鎖配電盤に用いて高圧地絡や高圧過電流によりVCBやLBS 等の主遮断装置がトリップして停電状態になった場合、無電圧a接点21を入力 接続する警報装置22は電源電圧Vを供給しているため、警報装置22は停電時 による電源電圧を補償するために図4のようにバッテリー25を設け、そのバッ テリー25から電源電圧を供給して警報動作を行っていた。また、ニッケルカド ミウム電池23のDC6Vの有電圧を入力接続する警報装置24は電源電圧を供 給されておらず、停電時にニッケルカドミウム電池23からのDC6Vを電源電 圧として供給して警報動作を行っていた。For example, when a main circuit breaker such as VCB or LBS is tripped due to a high voltage ground fault or a high voltage overcurrent in a high voltage closed switchboard and a power failure occurs, an alarm device 22 for input connection of a no-voltage a contact 21 is connected. Is supplied with the power supply voltage V, the alarm device 22 is provided with a battery 25 as shown in FIG. 4 in order to compensate for the power supply voltage due to a power failure, and the battery 25 supplies the power supply voltage to perform an alarm operation. Was there. In addition, the alarm device 24 that inputs and connects the voltage of DC6V of the nickel-cadmium battery 23 is not supplied with the power supply voltage, and in the event of a power failure, DC6V from the nickel-cadmium battery 23 is supplied as the power supply voltage to activate the alarm operation. I was going.
【0004】 また、1種類の警報装置22のみを用いてニッケルカドミウム電池23のDC 6Vの有電圧を入力接続したい場合は、図4のように警報装置22とニッケルカ ドミウム電池23のDC6Vの有電圧との間にDC6Vの有電圧を無電圧a接点 に変換する信号変換用リレー26を設けていた。また、これら図3,図4の警報 装置22,24の警報動作は通常LEDによる表示と、ブザーによる鳴動によっ て報知を行っていた。Further, when it is desired to input and connect the voltage of DC 6V of the nickel-cadmium battery 23 using only one type of alarm device 22, the voltage of DC 6V of the alarm device 22 and the nickel-cadmium battery 23 can be changed as shown in FIG. A signal conversion relay 26 for converting a voltage of 6 V DC to a non-voltage a contact is provided between the above and the above. Further, the alarm operation of the alarm devices 22 and 24 in FIGS. 3 and 4 is usually notified by the LED display and the buzzer sounding.
【0005】[0005]
しかしながら上記従来技術によると、図3のような場合は2種類の警報装置2 2,24を揃えなければならないという欠点があった。また、図4のような場合 においては1種類の警報装置22のみで構成することができるが、ニッケルカド ミウム電池23のDC6Vの有電圧を無電圧a接点に変換する信号変換用リレー 26を設けなければなたないため、非常に費用がかかる他、特別なスペースを必 要とするという欠点があった。また、通常ニッケルカドミウム電池23のDC6 Vの有電圧を入力接続する警報装置24は停電時においても警報動作を怠っては ならない場合のみに用いられるため、図4のように警報装置22を用いてニッケ ルカドミウム電池23のDC6Vの有電圧を入力接続する場合は、バッテリー2 5を設けなければならず、費用がかかるという欠点があった。 However, according to the above-mentioned conventional technique, in the case of FIG. 3, there is a drawback that two types of alarm devices 22 and 24 must be prepared. In the case of FIG. 4, the alarm device 22 can be configured by only one type, but a signal conversion relay 26 for converting the voltage of 6V DC of the nickel-cadmium battery 23 into a no-voltage a contact is provided. Since it is necessary to do so, it is very expensive and requires a special space. Further, since the alarm device 24 to which the voltage of DC 6 V of the nickel-cadmium battery 23 is normally connected is used only when the alarm operation should not be neglected even at the time of power failure, the alarm device 22 is used as shown in FIG. When inputting the voltage of DC6V of the nickel cadmium battery 23, the battery 25 must be provided, which is disadvantageous in cost.
【0006】 そこで本考案の目的は、夫々異なった種類の警報入力を1種類の警報装置で安 価に構成することができる警報装置を提供することにある。Therefore, an object of the present invention is to provide an alarm device in which different types of alarm inputs can be inexpensively configured with one alarm device.
【0007】[0007]
上記課題を解決するために、本考案の警報装置は、警報装置の警報入力端子に 無電圧接点及びDC有電圧のいずれを入力しても同様の警報動作を行うと共に、 DC有電圧の入力時は警報装置の電源電圧の有無に関わらず警報動作を行うもの である。 In order to solve the above problems, the alarm device of the present invention performs the same alarm operation regardless of whether a non-voltage contact or a DC voltage input is input to the alarm input terminal of the alarm device, and when a DC voltage is input. Is an alarm operation regardless of the presence or absence of the power supply voltage of the alarm device.
【0008】[0008]
警報装置に電源電圧が供給されているとき、警報入力端子に無電圧接点及びD C有電圧を入力した場合は共に警報動作を行う。また、停電等により警報装置に 電源電圧が供給されていないとき、警報入力端子に無電圧接点を入力しても警報 動作は行われないが、DC有電圧を入力した場合は警報動作を行う。 While the power supply voltage is being supplied to the alarm device, if a non-voltage contact and a DC voltage are input to the alarm input terminal, both alarm operations are performed. When the power supply voltage is not supplied to the alarm device due to a power failure or the like, the alarm operation will not be performed even if a non-voltage contact is input to the alarm input terminal, but the alarm operation will be performed if a DC voltage is input.
【0009】[0009]
本考案にかかる警報装置の一実施例を添付図面に基づいて説明する。 An embodiment of an alarm device according to the present invention will be described with reference to the accompanying drawings.
【0010】 図1は本考案にかかる警報装置の説明図、図2は図1における警報装置の内部 回路の説明図であり、警報装置1の警報入力端子T1,T2に無電圧a接点2及 びニッケルカドミウム電池3のDC6Vの有電圧のいずれを入力しても、LED による表示と、ブザーBZによる鳴動による同様の警報動作を行うと共に、DC 6Vの有電圧が入力されているときは警報装置1の電源電圧VDDの有無に関わら ず警報動作を行うものである。FIG. 1 is an explanatory diagram of an alarm device according to the present invention, and FIG. 2 is an explanatory diagram of an internal circuit of the alarm device in FIG. 1, in which alarm input terminals T1 and T2 of the alarm device 1 have a no-voltage a contact 2 and No matter which voltage of DC 6V of nickel cadmium battery 3 is input, the same alarm operation is performed by LED display and buzzer BZ, and when a voltage of DC 6V is input, an alarm device is activated. The alarm operation is performed regardless of the presence or absence of the power supply voltage V DD of 1.
【0011】 警報装置1に約DC5V以下の電源電圧VDDが供給され、警報入力端子T1, T2に無電圧a接点2を接続している場合において、無電圧a接点2が開路状態 のとき、トランジスタTr1はベースが「H」であるためオフ状態であり、トラ ンジスタTr2はベースとエミッタの電位差が生じないためオフ状態であり、ト ランジスタTr3はベースが「L」であるためオフ状態であり、警報動作を行う LED4と、ブザーBZは共にオフ状態である。また、異常を検出して無電圧a 接点2が閉路状態になったとき、トランジスタTr1はベースが「L」になりオ ン状態になる。そのため、ダイオードD1を介してトランジスタTr3のベース が「H」になると共に、オン状態になるため、LED4が発光して表示を行うと 共に、ブザーBZが鳴動を行い、異常を検出したことを報知する。このとき、ト ランジスタTr2はエミッタよりベースの方の電位が高いため、オフ状態のまま である。When the alarm device 1 is supplied with a power source voltage V DD of about 5 VDC or less and the non-voltage a contact 2 is connected to the alarm input terminals T1 and T2, when the no-voltage a contact 2 is in the open state, The transistor Tr1 is off because the base is "H", the transistor Tr2 is off because there is no potential difference between the base and the emitter, and the transistor Tr3 is off because the base is "L". , Alarm operation LED4 and buzzer BZ are both off. Further, when an abnormality is detected and the non-voltage a contact 2 is closed, the base of the transistor Tr1 becomes "L" and is turned on. Therefore, the base of the transistor Tr3 becomes "H" through the diode D1 and the transistor Tr3 is turned on, so that the LED 4 emits light to display and the buzzer BZ sounds to inform that an abnormality is detected. To do. At this time, the transistor Tr2 remains off because the potential of the base is higher than that of the emitter.
【0012】 また、上記と同様に警報装置1に約DC5V以下の電源電圧VDDが供給され、 警報入力端子T1,T2にニッケルカドミウム電池3のDC6Vの有電圧を接続 している場合において、DC6Vが警報入力端子T1,T2に入力されていない とき、トランジスタTr1,Tr2,Tr3は無電圧a接点2が開路状態で警報 入力端子T1,T2に接続されているときと同様であり、警報動作を行うLED 4と、ブザーBZは共にオフ状態である。また、異常を検出して警報入力端子T 1,T2からDC6Vが入力されたとき、約DC5Vの電源電圧VDDよりも電位 が高いため、抵抗R1から抵抗R2へ電流が流れ、抵抗R1に電位差が生じる。 このとき、電位差はトランジスタTr2のベースよりもエミッタの方が高くなる が、トランジスタTr2がオン状態になるために充分な電位差(0.7V以上) になるように抵抗R1と抵抗R2の抵抗値を設定しているため、抵抗R1の電位 差によりトランジスタTr2はオン状態になり、ダイオードD2を介してトラン ジスタTr3のベースを「H」になるため、トランジスタTr3はオン状態にな り、LED4とブザーBZに電圧を供給し、LED4が発光して表示を行うと共 に、ブザーBZが鳴動を行い、異常を検出したことを報知する。このとき、トラ ンジスタTr1はエミッタよりベースの方の電位が高いため、オフ状態になる。Further, in the same manner as above, when the power supply voltage V DD of about DC5V or less is supplied to the alarm device 1 and the voltage of DC6V of the nickel-cadmium battery 3 is connected to the alarm input terminals T1 and T2, DC6V Is not input to the alarm input terminals T1 and T2, the transistors Tr1, Tr2 and Tr3 are the same as when the non-voltage a contact 2 is open and connected to the alarm input terminals T1 and T2. Both the LED 4 to be performed and the buzzer BZ are off. Further, when DC6V is input from the alarm input terminals T1 and T2 when an abnormality is detected, since the potential is higher than the power supply voltage V DD of about DC5V, a current flows from the resistor R1 to the resistor R2 and the potential difference across the resistor R1. Occurs. At this time, the potential difference is higher at the emitter than at the base of the transistor Tr2, but the resistance values of the resistors R1 and R2 are set so that the potential difference becomes sufficient (0.7 V or more) for the transistor Tr2 to turn on. Since it is set, the transistor Tr2 is turned on due to the potential difference of the resistor R1, and the base of the transistor Tr3 is turned to “H” via the diode D2. Therefore, the transistor Tr3 is turned on and the LED 4 and the buzzer are turned on. A voltage is supplied to the BZ, the LED 4 emits light, and a display is made, and at the same time, the buzzer BZ sounds to notify that an abnormality has been detected. At this time, the transistor Tr1 is turned off because the potential of the base is higher than that of the emitter.
【0013】 停電等により警報装置1には電源電圧VDDが供給されず、警報入力端子T1, T2に無電圧a接点2を接続している場合において、無電圧a接点2が開路状態 及び閉路状態のとき、電源電圧VDDが供給されていないため、警報動作を行うL ED4と、ブザーBZは共にオフ状態である。When the power source voltage V DD is not supplied to the alarm device 1 due to a power failure or the like and the no-voltage a contact 2 is connected to the alarm input terminals T1 and T2, the no-voltage a contact 2 is in the open state and the closed state. In the state, since the power supply voltage V DD is not supplied, both the LED 4 that performs the alarm operation and the buzzer BZ are in the off state.
【0014】 また、停電等により警報装置1には電源電圧VDDが供給されず、警報入力端子 T1,T2にニッケルカドミウム電池3のDC6Vの有電圧を接続している場合 において、DC6Vが警報入力端子T1,T2に入力されていないとき、無電圧 a接点2が開路状態で警報入力端子T1,T2に接続されているときと同様であ り、警報動作を行うLED4と、ブザーBZは共にオフ状態である。また、異常 を検出して警報入力端子T1,T2からDC6Vが入力されたとき、電源電圧V DD が供給されているときと同様にトランジスタTr2はオン状態になり、DC6 Vの電位はダイオードD2を介してトランジスタTr3のベースを「H」になる と共に、ダイオードD4を介してLED4とブザーBZに電圧を供給し、トラン ジスタTr3はオン状態になり、LED4が発光して表示を行うと共に、ブザー BZが鳴動を行い、異常を検出したことを報知する。このとき、トランジスタT r1はエミッタよりベースの方の電位が高いため、オフ状態になる。In addition, due to a power failure or the like, the alarm device 1 receives a power supply voltage VDDIs not supplied and the voltage input of DC6V of the nickel-cadmium battery 3 is connected to the alarm input terminals T1 and T2. When DC6V is not input to the alarm input terminals T1 and T2, the no-voltage a contact 2 This is the same as when connected to the alarm input terminals T1 and T2 in the open state, and the LED 4 for performing the alarm operation and the buzzer BZ are both in the off state. When an abnormality is detected and 6V DC is input from the alarm input terminals T1 and T2, the power supply voltage V DD , The transistor Tr2 is turned on, the potential of DC6 V becomes “H” at the base of the transistor Tr3 via the diode D2, and the voltage is supplied to the LED4 and the buzzer BZ via the diode D4. Is supplied, the transistor Tr3 is turned on, the LED 4 emits light to display, and the buzzer BZ sounds to inform that an abnormality has been detected. At this time, since the potential of the base of the transistor Tr1 is higher than that of the emitter, the transistor Tr1 is turned off.
【0015】 そのため、上記のように構成された警報装置1は、1種類の警報装置1で停電 時による電源電圧を補償するためにバッテリーを設けることなく、警報入力端子 T1,T2に無電圧a接点及びニッケルカドミウム電池3のDC6Vの有電圧の いずれを入力しても同様の警報動作を行う他、DC6Vの有電圧を無電圧a接点 に変換する信号変換用リレーを設ける必要がないというものである。Therefore, in the alarm device 1 configured as described above, one type of alarm device 1 does not have a battery to compensate the power supply voltage due to a power failure, and the alarm input terminals T1 and T2 have no voltage a. The same alarm action will be performed regardless of whether the contact or the voltage of DC6V of the nickel-cadmium battery 3 is input, and it is not necessary to provide a signal conversion relay for converting the voltage of DC6V into a non-voltage a contact. is there.
【0016】 尚、上記実施例において、DC有電圧はニッケルカドミウム電池3のDC6V を用いているが、これは一例であって、DC有電圧はニッケルカドミウム電池3 のDC6Vに限定するものではなく、ニッケルカドミウム電池3以外の電池また 、DC6V以外のDC電圧等を供給するもともできる。また、その他の部品の構 成もこれに限定するものでなく、本考案の目的を逸脱しない範囲において、適宜 変更することができる。In the above embodiment, the DC voltage is DC6V of the nickel-cadmium battery 3, but this is an example, and the DC voltage is not limited to DC6V of the nickel-cadmium battery 3. It is also possible to supply batteries other than the nickel-cadmium battery 3 or a DC voltage other than DC 6V. Further, the configuration of the other components is not limited to this, and can be appropriately changed without departing from the object of the present invention.
以上説明したように、本考案にかかる警報装置は、警報装置の警報入力端子に 無電圧接点及びDC有電圧のいずれを入力しても同様の警報動作を行うと共に、 DC有電圧の入力時は警報装置の電源電圧の有無に関わらず警報動作を行うもの であるため、夫々異なった種類の警報入力を1種類の警報装置で安価に構成する 他、省スペース及び省施工であるという優れた効果を有するものである。 As described above, the alarm device according to the present invention performs the same alarm operation regardless of whether the non-voltage contact or the DC voltage is input to the alarm input terminal of the alarm device, and when the DC voltage is input. Since the alarm operation is performed regardless of the presence or absence of the power supply voltage of the alarm device, different types of alarm inputs can be inexpensively configured with one type of alarm device, and the excellent effect of saving space and construction is also achieved.
