Description
Technical field
The present invention relates to a kind of breaker mechanic property test Multifunctional navigation plugs for power engineering field to prolong
Long line component.
Background technique
The fast development of social economy promote nowadays electricity consumption of resident increasingly improve, the newly-built substation of each voltage class
It constantly builds like the mushrooms after rain and completes to put into operation.With being continuously increased for substation's quantity, substation equipment installation, handover
Test and maintenance work amoun are continuously improved.According to the equipment state overhauling requirement of national grid: the equipment state of 10KV breaker
Time between overhauls(TBO) is 4 years, and can at most be delayed 1 to 2 year according to equipment state evaluation, and the maintenance quantity of annual 10KV breaker is huge
Greatly, workload is very huge.
When overhauling to 10KV breaker, one of them overhauling project is to carry out mechanical characteristic test to breaker,
Measure switching on and off time, the spring, speed of breaker, switching on and off operation voltage of breaker etc., to determine each of breaker
Whether item actual parameter meets standard requirements, analyzes and determines whether breaker switching on and off spring aging occurs；Switching on and off mechanism
Whether appearance deformation, damage it is exceeded so as to cause action parameter, and determine breaker each section mechanism whether be adjusted to most
Good state.If breaker mechanic property is unqualified, after breaker puts into operation, if switching on and off operation voltage is unqualified
It is possible that refusing separating brake, refusing to close a floodgate, miss separating brake, false switching phenomenon.If it is the switching on and off time of breaker, spring, speed
To be likely to result in the breaker blow-out time elongated etc. unqualified, gently then causes breaker scaling loss, or even will cause breaker explosion
Major accident.So it is very necessary and have to do to carry out mechanical characteristic test to 10KV breaker.
When carrying out mechanical characteristic test to 10KV breaker, need to insert mechanic character tester device and breaker aviation
Head is attached.Test equipment sends voltage pulse by specified contact pin of the connecting line into breaker aviation plug.Blind plug
Interior specified contact pin is connected with circuit-breaker switching on-off coil, and voltage pulse drives circuit-breaker switching on-off coil motion to test point
Closing coil operation voltage value and using the corresponding full voltage pulse of divide-shut brake coil so that breaker actuation is to measuring
The parameters such as switching on and off time of breaker, spring, speed.But the aviation of mechanic character tester device and breaker is inserted at present
It perfect can not be connected between head, bring certain difficulty to construction to affect speed of application and safety.It is faced
Problem specifically includes that
1. since the model of 10KV breaker aviation plug is various, inserting in the 10KV breaker aviation plug of various models
Needle quantity, distribution and each function corresponding to contact pin physical location it is inconsistent, operating personnel can not differentiate rapidly 10KV open circuit
The function of the contact pin of device aviation plug is to be attached；
2. since contact pin quantity is more in breaker aviation plug, density is big, and the breaker aviation plug of different model
The sortord of interior contact pin, label location is all different, easily causes operating personnel contact pin selection mistake, wrong a line in connection
Or wrong one arranges, and can generate some unknown due to having connected some unknown circuits so as to cause input voltage when test
Failure or component wear；
3. the mechanical characteristic test instrument that the aviation plug of different model can not be unified with connector matches, when causing connection
Easily occur poor contact, connection built on the sand, the problems such as stability is insufficient.
