Description
Technical field
The utility model is related to a kind of measuring system, more particularly, is on a kind of measurement of on-load switch arc time
System.
Background technology
For the 3804-201X of standard GB/T that will be carried out《3.6kV~40.5kV high-voltage alternating on-load switches》The
6.101.10.2.2 require to provide the arc time in test report in money, but due to the particularity of on-load switch mechanism, it is often difficult
Accurately to measure the arc time.
At present, it is difficult to rely on theoretical calculation accurately to know the arc time in switchgear interrupting process, it is necessary to by reality
The border test measurement arc time, and then understand the arc-rupturing capacity of switch, because the change of voltage x current during arcing is more multiple
It is miscellaneous, while within the time that electric arc just starts appearance, the change of electric current and voltage is not obvious, therefore arcing time is often difficult to
Survey accurate, mainly by measuring opening time and switch off time to confirm the arc time, due to considering the limit of safety and instrument and equipment
System, opening time is measured typically under the conditions of major loop is not charged, and switch off time is measured in the case of major loop is powered, conventional feelings
Under condition opening time and switch off time be all it is powered for initial time with separating brake electrical apparatus release, it is special due to on-load switch mechanism
Property, some difficulties are often there are using this conventional measuring method, while needing contact during conventional method witness mark
Test product, when test failure in the presence of certain danger.
It is, thus, sought for it is a kind of more suitable, it is stable, while easily operated method determines initial time, Jin Erzhun
The system for really measuring the arc time, meets the requirement of standard.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art, applicant improves by repeatedly practice, devises a kind of on-load switch
The system of arc time measurement, it is safe and accurate.
Technical scheme：In order to realize foregoing invention purpose, the technical scheme that the utility model is used for：A kind of load is opened
The system for closing arc time measurement, including on-load switch, photoelectric sensor, master control room, the photoelectric sensor, which is installed in, to be risen
On descending branch frame, the support is 360 ° of rotations, sets at regular intervals between the photoelectric sensor and on-load switch, the master control
Room includes acquisition system and shielding system, and the acquisition system is connected with photoelectric sensor by shielded cable.
Further, the photoelectric sensor includes laser, amplifier, and the photoelectric sensor is high power laser class
Sensor.
Yet further, the main shaft of the on-load switch is connected with movable connecting rod.
Beneficial effect：Compared with prior art, its advantage is the utility model：
1st, the utility model is not contacted directly with on-load switch due to photoelectric sensor, security and anti-interference be better than with
On-load switch has other metering systems being directly electrically connected, and photoelectric detecting method has that precision is high, swift advantage,
Influence very little for being tested on-load switch mechanical property.
2nd, the connecting rod range of choice that the utility model is used is wider, therefore can be incorporated in many of different institutions type extensively
On-load switch, including on-load switch manually or electrically are planted, it is applied widely.
4th, acquisition system of the present utility model is located in master control room, by shielding electricity between acquisition system and spot sensor
Cable is connected, so as to reduce the influence of interference signal, and then accurately measures the arc time.
5th, photoelectric sensor of the present utility model is installed in a height and can lift and facilitate 360 ° of rotations of sensor
On support, the link trajectory of different test products has been adapted to.
Brief description of the drawings
Fig. 1 is a kind of measuring loop schematic diagram of the system measured on-load switch arc time.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection of the present utility model
Scope is not limited to the embodiment.
As shown in figure 1, a kind of system of on-load switch arc time measurement, including on-load switch, photoelectric sensor, master control
Room, the photoelectric sensor is installed on liftable support, and the support is 360 ° of rotations, and the photoelectric sensor is opened with load
Set at regular intervals between pass, the master control room includes acquisition system 7 and shielding system 6, the acquisition system 7 and photoelectric sensing
Device is connected by shielded cable 5.
The photoelectric sensor includes laser 3, amplifier 4, and the photoelectric sensor is high power laser class sensor.
The main shaft 1 of the on-load switch is connected with movable connecting rod 2.
The connecting rod 2 moved by the main shaft 1 switched with lotus is opened the photoelectricity blocked inside triggering photoelectric sensor of light
Close, then be sent to by the actuating signal of optoelectronic switch in the acquisition system of master control room, and then know the starting the arc moment.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
