The working principle of the running-in test system of the breaker operation mechanism of the present embodiment are as follows: press manual actuation of button
FA, separating brake relay coil 1ZJ obtain it is electric, when unclamping manual actuation of button FA, separating brake relay coil 1ZJ again can power loss, but
It is the effect due to the first normally opened contact 2SJ1 of opening time relay, even if manual actuation of button FA is unclamped, due to separating brake
Branch where first normally opened contact 2SJ1 of the time relay is constantly in energized state, it will makes separating brake relay coil
1ZJ always it is electric, at this time corresponding separating brake relay the second normally opened contact 1ZJ3 closure, breaker operation mechanism separating brake examination
Branch conducting is tested, separating brake running-in test is carried out to breaker operation mechanism.Since string is equipped with combined floodgate in separating brake timing control loop
The normally-closed contact 1ZJ2 of relay, when separating brake relay coil 1ZJ obtains electric, the normally-closed contact 1ZJ2 of separating brake relay is disconnected,
Make separating brake timing control loop akinesia, ensure that the safety of breaker operation mechanism running-in test system.
Then separating brake relay the first normally opened contact 1ZJ1 closure, closing time relay coil 1SJ obtain it is electric, at this point,
If the first normally opened contact 1ZJ1 of separating brake relay is disconnected due to failure cause, first due to closing time relay is normal
Open the self-locking of contact, can make opening time relay coil 1SJ always it is electric, the first of corresponding closing time relay
Normally opened contact 1SJ2 closure, obtains separating brake relay coil 2ZJ electric, then the second normally opened contact 2ZJ3 of separating brake relay is closed
It closes, the combined floodgate test branch conducting of breaker operation mechanism carries out combined floodgate running-in test to breaker operation mechanism.
At this point, closing time relay coil 1SJ power loss is divided if closing time relay delay time reaches setting value
First normally opened contact 1ZJ1 of lock relay is disconnected, separating brake relay coil 1ZJ power loss, the second normally opened contact of separating brake relay
1ZJ3 is disconnected, and the separating brake running-in test of the operating mechanism of breaker terminates.
The first normally opened contact 2ZJ2 closure of closing relay simultaneously, makes opening time relay coil 2SJ obtain electric, separating brake
Second normally opened contact 2SJ2 of the time relay is closed, due to the self-locking work of the second normally opened contact 2SJ2 of opening time relay
With, make opening time relay coil 2SJ always it is electric, until opening time relay reaches the delay time of setting, separating brake
Second normally opened contact 2ZJ3 of time relay coil 2SJ power loss, separating brake relay is disconnected, the combined floodgate of the operating mechanism of breaker
Running-in test terminates.Simultaneously because string is equipped with the normally-closed contact 2ZJ1 of separating brake relay in the first combined floodgate timing controlled branch, when
When closing relay coil 1ZJ obtains electric, the normally-closed contact 1ZJ2 of closing relay is disconnected, and be can be carried out sub-switching operation not, is prevented
It separating brake and closes a floodgate while carrying out, ensure that the safety of breaker operation mechanism running-in test system.
During carrying out divide-shut brake running-in test, the number of divide-shut brake running-in test can also be counted, such as
The number that breaker operation mechanism divide-shut brake running-in test has been determined before fruit test, then need to only be arranged circuit-breaker switching on-off
The number of running-in test, after reaching breaker actuating running-in test number, running-in test is automatically stopped.As shown in Figure 1, adjustment
The counting process of test number (TN) are as follows: if separating brake of every progress and closing operation count once, if combined floodgate running-in test
It is carrying out, the second normally opened contact 2SJ3 closure of opening time relay, counter coil JS2 obtains electric, corresponding counter
Normally opened contact JS closure, the normally-closed contact of counter disconnect JS1 and disconnect, and count primary.Then manual actuation of button progress is pressed
Second of counting, repetitive cycling carry out divide-shut brake running-in test, the test number (TN) until reaching setting.
Electric power loop both ends are also connected in parallel to voltage regulator AT, can be according to the big minor adjustment of breaker operation mechanism
Device required voltage exports a certain size alternating voltage to breaker actuating machine when changer contact ZK1, ZK2 closure
Structure coil is grasped by the DC voltage that rectifier bridge exports a certain size to breaker when changer contact ZK3, ZK4 closure
Dynamic actuator coil, regulative mode is flexible, is adapted to the development need of breaker.
Specific embodiment is presented above, but the utility model is not limited to embodiment described above.This
The basic ideas of utility model are above-mentioned basic scheme, for those of ordinary skill in the art, according to the present utility model
Introduction, the model, formula, parameter for designing various modifications do not need to spend creative work.The utility model is not being departed from
Principle and spirit in the case where the guarantor of the utility model is still fallen within to variation, modification, replacement and the deformation that embodiment carries out
It protects in range.
