A kind of voltage-time type feeder test method, comprising the following steps:
Step 1, equipment connection, as shown in Figure 1:
Firstly, switch 1 and line feed terminals 1 are connected with each other；Switch 2 and line feed terminals 2 are connected with each other；By switch 3 and feeder line
Terminal 3 is connected with each other.Specifically, switch 1 and line feed terminals 1 are connected with each other, control terminal and line feed terminals 1 including switch 1
Control terminal is connected with each other, and the signal end of switch 1 and the test side of line feed terminals 1 are separately connected.By switch 2 and 2 phase of line feed terminals
It connects, the control terminal of the control terminal including switch 2 and line feed terminals 2 is connected with each other, the signal end and line feed terminals 2 of switch 2
Test side be separately connected.Switch 3 and line feed terminals 3 are connected with each other, the control of the control terminal including switch 3 and line feed terminals 3
End processed is connected with each other, and the signal end of switch 3 and the test side of line feed terminals 3 are separately connected.The company of above-mentioned switch and line feed terminals
It connects as existing connection type, without special place.
The source side of switch 1 is connect with the alternating voltage output interface 1 on voltage-time type logic tester；Switch 1
Load side is connect with the source side of switch 2；The load of switch 2 is connect with the source side of switch 3, the load side and voltage of switch 3
Alternating voltage output interface 2 on time type logic tester connects.
1 end of the position of the switch of line feed terminals 1,2 end of the position of the switch of line feed terminals 2, line feed terminals 33 end of the position of the switch
It is connect respectively with the position of the switch interface on voltage-time type logic tester.
Here voltage-time type logic tester is that can export two-way alternating voltage and there is position of the switch interface to adopt
Collect the device of function, or is replaced using relay-protection tester.
Step 2, configuration switch: after carefully connecting the wire, segmented model is configured by switch 1 and switch 2；Switch 3 is configured to join
Network mode.
Alternating voltage output interface 1 and voltage-time type logic tester in step 3, voltage-time type logic tester
On the output AC voltage simultaneously of alternating voltage output interface 2, after be waited 10 seconds after switch 1 and 2 automatic closing of switch.It waits
10S is primarily to escape the Y time limit for starting timing after line feed terminals control switch is closed a floodgate.The Y time limit is generally 5S.
Step 4, the alternating voltage for stopping the alternating voltage output interface 1 on voltage-time type logic tester export, so
It waits 5 seconds afterwards.Alternating voltage output interface 1 exports again after waiting 5S, mainly the imitating substation outlet breaker time of coincidence,
Generally 5S.
Alternating voltage output interface 1 in step 5, voltage-time type logic tester output AC voltage again, waits
Switch 1 stops the alternating voltage output of the alternating voltage output interface 1 on voltage-time type logic tester again after closing a floodgate, so
It waits again afterwards 5 seconds.After AC output interface 1 stops output, due to the power supply side and load side decompression of switch 1 and switch 2, feeder line
Terminal can control switch tripping.
Alternating voltage output interface 1 in step 6, voltage-time type logic tester output AC voltage again, waits
45 seconds.Again after output AC voltage, switch 1 is because alternating voltage output interface 1 stops output and loses after closing a floodgate in steps of 5
Separating brake is pressed, since less than Y time limit (5S), it can be latched source side and obtain electric combined floodgate for timing after closing a floodgate.In step 6, alternating voltage
Output interface 1 again output AC voltage it will not close a floodgate.And 2 source side of switch is divided due to the combined floodgate of switch 1 in steps of 5
Pulse signal is detected during lock, will form the block signal that a locking load side obtains electric combined floodgate.Due to interconnection switch list
Side decompression separating brake, it can automatic closing after 45 seconds.Switch 2 is not since the presence of block signal is closed a floodgate, disconnecting switch 1 and switch 2
Between failure.
Step 7, the shape that switch 1, switch 2, switch 3 are acquired from the position of the switch interface on voltage-time type logic tester
State, if switch 1 and switch 2 are gate-dividing state and switch 3 is "on" position, test passes through, and otherwise tests and does not pass through.Voltage time
Type logic tester collects switch position signal, by judging the position of switch 1-3, shows (liquid crystal in human-computer interaction interface
Show screen).According to relay-protection tester, the separating brake situation and line feed terminals 1 and 2 of observation switch 1-3 are gone by people
Block signal can determine whether test result.
