Abstract
The utility model relates to a fuse component with open circuit indication. A traditional fuse of a single structure has no corresponding indication after fuses, when the number of fuses in an electric system is large, certain time need spending to find the fuse which is fused, which is adverse to the quick recovery of the electric system. The fuse component with open circuit indication of the utility model comprises the fuse connected with a power supply circuit in series, a current limiting resistor and a light emitting piece, wherein the current limiting resistor and the light emitting piece are connected in series to form a series circuit which is connected with the fuse in parallel. After the fuse in the fuse component of the utility model is fused, the light emitting piece of the fuse component emits light and indicates a corresponding fault. In one embodiment of the utility model, the light emitting piece can adopt a neon bulb.
Description
Technical field
The utility model is relevant for the fuse that uses in the electric power system, specifically, relates to the open circuit fuse component of indication of a kind of band, when this fuse component is installed in the supply line, can show this fuse situation that whether opened circuit.
Background technology
All power consumption equipments generally all are equipped with fuse (perhaps fusible link, current limliting silk etc.) in order to protect the safe in utilization of itself.The effect of fuse is: power consumption equipment causes that as breaking down electric current is excessive in the course of the work; the limit that has surpassed fuse itself; then fuse is protected power consumption equipment and electric power system for because of the excessive fusing voluntarily of electric current thereby play, and avoids the damage of big electric current.
For example, in the family expenses electric power system, the fuse of certain current value is housed all at the input and output side of ammeter.Mostly use the three-phase electricity of 380V in the industrial and mining enterprises, each mutually all must the installation insurance silk.For some main equipments, the installation quantity of fuse is according to the requirement of equipment and fixed, tens at most, also has two, three at least.In case break down in a certain road, the fuse on a certain road has been fused, under the situation that does not now have indication, will be finding out in the fuse of fusing (burning) in tens, need the suitable time of cost, check one by one, influenced fast quick-recovery to a certain extent power supply.
The utility model content
Therefore, the purpose of this utility model is to provide a kind of fuse component with the indication of opening circuit, and when the fuse in this assembly is fused, makes indication by tangible sign to the user, be convenient to the user and find the fuse that burns fast, so that make maintenance reflection fast.
According to above-mentioned purpose, the fuse component that the utility model provides a kind of band to open circuit indication, comprise a fuse, be serially connected in the supply line, it is characterized in that, also comprise a current-limiting resistor and an illuminating part, described current-limiting resistor and illuminating part series connection form series circuit, and this series circuit is in parallel with described fuse.
2, fuse component as claimed in claim 1 is characterized in that, the resistance value of described current-limiting resistor is greater than 1M ohm.Described current-limiting resistor, its power is for being equal to or greater than 0.1 watt.
3, fuse component as claimed in claim 1 is characterized in that, described illuminating part is a neon bulb, and the resistance of described current-limiting resistor is 5M ohm.Described current-limiting resistor power is for being equal to or greater than 0.1 watt.
Because the utility model has increased an illuminating part in fuse component, when operate as normal, illuminating part flows through because of no current, and is not luminous.When fuse is fused, electric current will flow through illuminating part, make corresponding illuminating part luminous, reach the purpose that indicate fuse is fused by this illuminating part.
Description of drawings
Fig. 1 is the circuit structure diagram of fuse component of the present utility model and the application in side circuit.
Embodiment
As shown in Figure 1, Fig. 1 shows the circuit structure diagram of an embodiment of fuse component of the present utility model.Be the circuit structure of the fuse component of embodiment shown in the frame of label B indication among Fig. 1.Fuse BX is serially connected in the current supply circuit in a conventional way.In current supply circuit, all right tandem tap K and K1, K switch and K1 can be linked switches.HL represents power consumption equipment, and fuse BX is connected the live wire end of current supply circuit, and electric current enters into power consumption equipment HL through K switch, fuse BX, turns back to zero line by K switch 1 then, forms current circuit.
As shown in Figure 1, in fuse component of the present utility model, except fuse BX, also include a current-limiting resistor R and an illuminating part HA.Current-limiting resistor R and illuminating part HA series connection constitute a series connection circuit, and this series circuit is in parallel with fuse BX.When operate as normal, almost nil because of the resistance value of fuse BX is very little, and the current-limiting resistor resistance is very big.Therefore, electric current can not flow through the series circuit of current-limiting resistor R and illuminating part HA formation, and illuminating part HA is not luminous.When cause fuse BX to be fused because of a variety of causes, then electric current will flow through current-limiting resistor R and illuminating part HA through series circuit.Because of the effect of current-limiting resistor R, the current value that flows through illuminating part HA and power consumption equipment HL is very little, only can make illuminating part HA luminous, can not damage power consumption equipment HL.Thereby illuminating part HA has indicated the fuse BX in this assembly to be fused by luminous to the user, makes things convenient for the user to determine the source of trouble fast, fixes a breakdown, and restores electricity.
In the above-described embodiment, the resistance value of current-limiting resistor R is generally chosen more than 1M ohm, and voltage is pressed on the current-limiting resistor R most of the branch.Illuminating part HA can adopt neon bulb, and under the situation that adopts neon bulb, the resistance value of current-limiting resistor R may be selected in 5M ohm, and the current value that produce this moment in series circuit is greatly about 44 μ A.This electric current can be lighted neon bulb, but can not start various power consumption equipments.
In the embodiment in figure 1, according to the requirement of routine, a fuse component B1 of the present utility model can also be installed at zero line K switch 1 place.
