Detailed description of the invention
Present invention will be further described below with reference to the accompanying drawings and specific embodiments:
Fig. 1 is typical breaker mechanism anti-jump loop simplified pinciple figure；
Fig. 2 is time/auxiliary contacts of circuit breaker, anti-trip relay contact opening and closing situation map.
Specific embodiment
It is anti-jump, briefly it is exactly to prevent breaker from jumping, that is, prevents breaker ceaselessly division.Conventional test method
It is persistently to send out switching signal to breaker first, then gives one sub-gate signal of breaker, if Anti-jump Circuit of Breaker is reliable,
Breaker should be close a floodgate it is primary after separating brake again, be then always held at open position.It is double from the point of view of current operating experience
The route protection for changing configuration again also occurs that following special circumstances, i.e., breaker first receives sub-gate signal, then receives switching signal
(for example a set of protection has had been sent from rear Accelerated trip signal, and another set of protection reclosing signal does not release also but).Conventional
Test method cannot test out the reliability of the Anti-jump Circuit of Breaker movement in special circumstances.
The present invention provides a kind of Anti-jump Circuit of Breaker test method, the test method can test out various situations (including
The above special circumstances) under the reliability that acts of anti-jump loop, and find out the reason of cannot correctly acting.Below in conjunction with Fig. 1 and
Fig. 2 makes breaker mechanism anti-jump loop test method of the invention and illustrates.
As depicted in figs. 1 and 2, a kind of Anti-jump Circuit of Breaker test method,

T1 is that breaker normally-closed contact first switches on the time, and T2 is breaker normally opened contact first time closing time, T3
The time opened again after being closed for the first time for breaker normally opened contact, T4 are to be closed again after breaker normally-closed contact first switches on
Time, t1 be anti-trip relay normally-closed contact actuation time, t2 be anti-trip relay normally opened contact actuation time
It can be seen that breaker anti-trip relay (FTJ) since Fig. 1 and Fig. 2 to act the T2 moment, T2+t2 moment FTJ
Normally opened contact closure, T2+t1 moment FTJ normally-closed contact closure.After normally-closed contact closure, if switching signal also exists always, prevent
Road is jumped back to just really to work.The other very little of usual t1 and t2 value difference, can be approximately considered identical.
Anti-jump loop is unqualified usually following three kinds of situations:
1), T1 > > T2, then anti-jump loop may be unqualified, can make by adjusting the actuation time of breaker normally-closed contact
Anti-jump loop is qualified；
If 2), T3-T2 < t1, and 20 milliseconds of T3-T2 >, anti-trip relay does not have enough time also acting, anti-jump loop just by
It disconnects, this is to cause most of underproof reason of mechanism anti-jump loop at present, then anti-trip relay can be replaced, using quick
The anti-trip relay of movement keeps anti-jump loop qualified；
It if 3), 20 milliseconds of T3-T2 <, is caused fastly very much since breaker normally opened contact acts, it can be by adjusting disconnected
The actuation time of road device normally opened contact keeps anti-jump loop qualified；
By the actuation time analysis above to auxiliary contact actuation time and breaker anti-trip relay, can determine
The underproof reason of anti-jump loop, suits the remedy to the case, and anti-jump loop is enable to play reliable protective effect.And this method can test out
