Specifically, on-off of the line vacuum circuit breaker using a main contact control high voltage supply, therefore switch closing and switch opening is equal
The movement of a corresponding main contacts.And line air blast circuit breaker is using the logical of main contact and disconnecting switch co- controlling high voltage power supply
Disconnected, under original state, main contact closure, disconnecting switch is disconnected, so that the non-off-state of overall performance, when combined floodgate is tested, main touching
Head state is constant, disconnecting switch closure, therefore when the disconnecting switch closing moment of the motion end of main circuit breaker and control terminal combined floodgate
The difference carved is the closing time of main circuit breaker.And during the opening process, main contact and disconnecting switch can be opened successively, main open circuit
The difference that the main contact of the motion end of device opens moment and control terminal separating brake moment is opening time, the motion end of main circuit breaker every
Leaving and closing the difference for opening moment and control terminal separating brake moment is delay time.
In conclusion different according to the type of main circuit breaker, in separating brake test, the count value number of second timer is not
Together, in line vacuum circuit breaker, the count value number of second timer is 1, in line air blast circuit breaker, the counting of second timer
Being worth number is 2.
Step 4, second control module are counted the third count value and the described 4th by wireless communication mode,
Or third count value, the 5th count value and the 6th count value are transmitted to first control module.
Optionally, second control module is counted the third count value and the described 4th by wireless communication mode
Several or third count value, the 5th count value and the 6th count value may be used also before being transmitted to first control module
To include: to establish the host and the slave by first wireless communication module and second wireless communication module
It is wirelessly connected.
It should be noted that when the time for establishing above-mentioned wireless connection can be to test beginning, or the second control
Before module data to be transmitted, can rationally it be arranged according to the actual situation, the present embodiment is not specifically limited in this embodiment.
Step 5, first control module are according to the multiple count values and first count value and second received
Count value obtains the time parameter of the tested main circuit breaker.
Illustratively, multiple count values that first control module receives are the third count value and the described 4th
When count value, the time parameter includes closing time and opening time.Multiple countings that first control module receives
Value is the third count value, the 5th count value and when six count value, the time parameter include closing time,
Opening time and delay time.
Correspondingly, multiple count values that first control module receives are the third count value and the 4th meter
When numerical value, first control module is obtained according to the multiple count values and first count value that receive and the second count value
The tested main circuit breaker time parameter may include: using the difference of the third count value and first count value as
The closing time, using the difference of the 4th count value and second count value as the opening time.
Alternatively, multiple count values that first control module receives are the third count value, the 5th counting
Value and when six count value, first control module according to the multiple count values and first count value received with
And second count value to obtain the time parameter of the tested main circuit breaker may include: by the third count value and described first
The difference of count value is as the closing time, using the difference of the 5th count value and second count value as when the separating brake
Between, using the difference of the 6th count value and the 5th count value as the delay time.
Technical solution provided in this embodiment, by the way that first timer and the first synchronous port are arranged in host, in pair
Setting second timer and the second synchronous port in machine, when so that test starting, first timer in the first control module and
Second timer in second control module can be opened simultaneously, and generate triggering in the control terminal of tested main circuit breaker respectively
The motion end of movement and tested main circuit breaker is counted when generating corresponding response action, in addition, being set to the in host
One wireless communication module and the second wireless communication module being set in slave can establish wirelessly connecting between host and slave
It connects, the count value for the second timer that slave is stored is transferred to host, and then host can be fixed according to first
When device count value and the count value of second timer obtain the time parameter of tested main circuit breaker.Compared with the existing technology, have
There is the test device of above structure to connect host and slave without using test cable, so reduce test equipment weight and
Volume improves the convenience and testing efficiency of test equipment test.
