Description
Technical field
The utility model is related to the technical fields of test, more particularly, to switch testing auxiliary tool.
Background technology
According to《Southern Power Grid Company power equipment preventive trial regulation》Relevant regulations, the busbar in vacuum circuit breaker
Every 3 years 1 time of network interconnecting circuit, main transformer low-pressure side breaker, capacitor group breaker, remaining 6 years 1 time carry out operating mechanism combined floodgate
The operation voltage of contactor and switching on and off electromagnet is tested.
The VD4 series that the 10kV vacuum circuit breakers of most of substations of present Foshan power supply bureau mostly use greatly ABB AB can
Pull-out type vacuum circuit breaker.This breaker is attached using the secondary circuit of 60 core rectangle aviation plugs and cabinet, tradition
Test method use method be to be in direct contact connecing in the male plug being connected with breaker using the metal part of test wire
Terminal, while this breaker, there are closing locking relay, testing crew need to open cover board, manual unlocking can be to disconnected
The switching electromagnet of road device is tested.
There are following drawbacks for conventional test methods：
1, breaker cover board need to be removed, test period is enabled to increase；
2, closing locking is released manually, if undue force easily causes locking relay damage.Meanwhile closing locking relay
Closer with the mechanical operating mechanism distance of breaker, testing crew clothing is occurred easily during switch motion in volume such as mechanism
It is dangerous；
3, easily there is the accuracy that test lead is bad with breaker Aviation Connector and influence is tested.
Invention content
The utility model is at least one defect overcome described in the above-mentioned prior art, provides switch testing auxiliary tool,
VD4 series switch test job efficiency can be improved, reduce work risk.
The technical solution of the utility model is：Switch testing auxiliary tool, wherein including patch panel, patch panel packet
Include public port, separating brake port, combined floodgate port, cable port, the public port, separating brake port, combined floodgate port, cable end
The lower part of mouth is equipped with control voltage selection port, closing locking control port, control loop port.
This tool utilizes thyristor full-wave rectification principle, and the AC220V power supplys of experiment are converted into breaker control circuit
Required DC110V/220V, the closing locking for releasing breaker.
According to the electric drawings of VD4 Series Circuit Breakers, judge breaker switching on and off circuit in Aviation Connector
Core number, and be connected with the quick coupling on tool, testing crew only needs to be inserted into test lead in the quick coupling of tool, just
Breaking-closing operating can be carried out to breaker.
Compared with prior art, advantageous effect is：This tool has the ability of output DC110V/220V, can be in open circuit
Device makes closing locking relay unlocking when need to close a floodgate, without opening the cover board of breaker, improve test efficiency, save examination
Test the time；This tool is connected using aviation female connector with breaker, the case where connecting robust, avoid poor contact.Examination
The personnel of testing need not release closing locking manually, be not in that testing crew clothing is rolled up easily during switch motion as in mechanism
The case where, improve the safety of operation.
Description of the drawings
Fig. 1 is the utility model auxiliary tool patch panel schematic diagram.
Fig. 2 is the utility model control circuit principle schematic.
Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1, 2, switch testing auxiliary tool, wherein including patch panel, patch panel includes public port,
Separating brake port, combined floodgate port, cable port, the public port, separating brake port, combined floodgate port, cable port lower part set
There are control voltage selection port, closing locking control port, control loop port.
This tool utilizes thyristor full-wave rectification principle, and the AC220V power supplys of experiment are converted into breaker control circuit
Required DC110V/220V, the closing locking for releasing breaker.
According to the electric drawings of VD4 Series Circuit Breakers, judge breaker switching on and off circuit in Aviation Connector
Core number, and be connected with the quick coupling on tool, testing crew only needs to be inserted into test lead in the quick coupling of tool, just
Breaking-closing operating can be carried out to breaker.
In addition, being connect with binding post using insulation joint sleeve, it can also achieve the effect that connection fastening.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.All any modification, equivalent and improvement made within the spirit and principle of the present invention etc., should be included in
Within the protection domain of the utility model claims.
