Actuation time of the node FT-2 after closing operation, i.e., the opening time of normally closed node FT-2, change-over switch 4 is by timing at this time
Monolithic machine-cut will be opened and be connect into dry node at combined floodgate node both ends on the first micro treatment module, and output binding post for first
It connects at the both ends of the normally closed contact FT-2 of anti-trip relay, after the time switch 15 for pressing the anti-jump test device of breaker, the
One timing module starts timing, while giving combined floodgate contact one pulse progress feed motion by outputing dry node 3, after combined floodgate,
Breaker closing coil HQ is powered, the auxiliary node DL2 of breaker closure, after the coil FT of anti-trip relay is powered, it is anti-jump after
The normal opened contact FT-1 of electric appliance is closed, and forms the self-holding circuit of anti-trip relay, while the normally closed node FT- of anti-trip relay
2 open, and open into binding post 16 by first to one pulse signal of first singlechip, the first timing module stops timing, passes through
After first digital display module 14 is shown in feed motion, the actuation time of the normally closed node FT-2 of anti-trip relay.
Then it tests in sub-gate circuit, after sub-switching operation, the closing time of the normally closed node DL of breaker is opened by conversion
It closes 4 and the single-chip microcontroller of timing is switched into the second micro treatment module, will open and connect into dry node at separating brake node both ends, and second is opened
Binding post connects at the both ends of the normally closed node DL of breaker out, after the time switch 15 for pressing the anti-jump test device of breaker,
Second timing module starts timing, while carrying out separating brake movement, separating brake behaviour to one pulse of separating brake contact by outputing dry node 3
When making, the state of breaker at this time is "on" position, and therefore, the state of the normally closed contact DL of breaker is in an open state, separating brake
The breaking coil of breaker is powered afterwards, and the normally closed node DL of breaker becomes closed state after DL is closed from opening state and passes through
Second, which outputs binding post, gives second singlechip one pulse signal, and the second timing module stops timing, passes through the second digital display module
After 24 are shown in separating brake movement, the actuation time of breaker normally closed contact DL.
At this point, after the first digital display module 14 shows closing operation, the actuation time of anti-trip relay normally closed contact FT-2,
After second digital display module 24 shows sub-switching operation, the actuation time of breaker normally closed contact DL, by comparing, when anti-jump relay
When the actuation time of device normally closed contact FT-2 is greater than the actuation time of breaker normally closed contact DL, it is believed that anti-in the anti-jump loop
Jumping test result is qualification.
