Anti-trip relay starts action, T2+t2 moment anti-trip relay normally opened contact closure, T2+t1 moment anti-jump relay at the T2 moment
Device normally-closed contact is closed, wherein,
If 1) T1>>T2, then anti-jump loop may be unqualified, makes to prevent by adjusting the actuation time of breaker normally-closed contact
Rebound road is qualified；
If 2) T3-T2 ＜ t1, and 20 milliseconds of T3-T2 ＞, then can change anti-trip relay, use the anti-jump of quick acting
Relay makes anti-jump loop qualified；
It is due to that the action of breaker normally opened contact causes very much soon if 3) 20 milliseconds of T3-T2 ＜, it is normal by adjusting breaker
Opening the actuation time of contact makes anti-jump loop qualified.
The technical solution adopted by the present invention, breaker first persistently sends out sub-gate signal, then hold under point position state to breaker
Continue and send out switching signal to breaker, and be always maintained at switching signal up to breaker energy storage is finished, then analyze point of breaker
Combined floodgate situation, perfect test mode, expands test scope.
In addition, the present invention is by analyzing auxiliary contact actuation time and the actuation time of breaker anti-trip relay, can
To determine the underproof reason of anti-jump loop, suit the remedy to the case, anti-jump loop is played reliable protective effect.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
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.
Embodiment
It is anti-jump, it is exactly briefly to prevent breaker from jumping, that is, prevents breaker ceaselessly division.Conventional method of testing
It is persistently to send out switching signal to breaker first, then gives breaker one sub-gate signal, if Anti-jump Circuit of Breaker is reliable,
Breaker should be separating brake again after closing a floodgate once, then be always held at open position.It is double from the point of view of current operating experience
Change the route protection of configuration again it also occur that following special circumstances, i.e. breaker first receive sub-gate signal, then receive switching signal
(such as a set of protection has had been sent from rear Accelerated trip signal, and another set of protection reclosing signal is not released also but).Conventional
Method of testing can not test out the reliability of the in particular cases Anti-jump Circuit of Breaker action.
The present invention provides a kind of Anti-jump Circuit of Breaker method of testing, the method for testing can test out various situations (including
Above special circumstances) under the reliability that acts of anti-jump loop, and find out the reason for being unable to correct operation.Below in conjunction with Fig. 1 and
Fig. 2 makes to the breaker mechanism anti-jump loop method of testing of the present invention and illustrated.
As depicted in figs. 1 and 2, a kind of Anti-jump Circuit of Breaker method of testing,
First, breaker first persistently sends out sub-gate signal under point position state to breaker, then persistently gives breaker hair combined floodgate
Signal, is always maintained above switching signal until breaker energy storage is finished, if breaker only occurs once to close in whole process
Lock and separating brake, then anti-jump loop is qualified, if occurring multiple division, anti-jump loop is unqualified.
Secondly, it is unqualified after, detect breaker anti-trip relay actuation time and auxiliary contacts of circuit breaker action when
Between, comparative analysis actuation time determines the underproof reason of anti-jump loop.
, the actuation time of breaker anti-trip relay and the actuation time of auxiliary contacts of circuit breaker, can be with reference to shown in Fig. 2
Set up the chart shown in Fig. 2 and carry out com-parison and analysis.
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 is after breaker normally-closed contact is first switched on and closed
Time, t1 be anti-trip relay normally-closed contact actuation time, t2 be anti-trip relay normally opened contact actuation time
Breaker anti-trip relay (FTJ) is can be seen that since Fig. 1 and Fig. 2 to act the T2 moment, T2+t2 moment FTJ
Normally opened contact is closed, T2+t1 moment FTJ normally-closed contact closure.After normally-closed contact closure, if switching signal also exists always, prevent
Just really work on rebound road.The other very little of usual t1 and t2 value differences, can be approximately considered identical.
Anti-jump loop is unqualified generally following three kinds of situations：
1)、T1>>T2, then anti-jump loop may be unqualified, can be made 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 be not in time for also action, anti-jump loop just by
Disconnect, this is to cause most of underproof reason of mechanism anti-jump loop at present, then anti-trip relay can be changed, using quick
The anti-trip relay of action makes anti-jump loop qualified；
It is due to that the action of breaker normally opened contact causes very much soon if 3), 20 milliseconds of T3-T2 ＜, can be disconnected by adjustment
The actuation time of road device normally opened contact makes anti-jump loop qualified；
Auxiliary contact actuation time and the actuation time of breaker anti-trip relay are analyzed more than, it may be determined that go out
The underproof reason of anti-jump loop, suits the remedy to the case, and anti-jump loop is played reliable protective effect.And this method can be tested out
