Voltage-time type logic tester method of testing, including,
Distribution terminal logic testing is carried out, including enters line delay and closes logic testing, carry out X time limits locking test, carry out
Both sides voltage blocking test, carry out Y time limits locking test;
Block switch opening time test is carried out, it is automatic to record block switch opening time value, if during block switch separating brake
Between value more than transformer substation switch reclosure time, then block switch opening time is normal;
Block switch opening time is tested for testing block switch opening time, it is ensured that opening time is opened more than transformer station
The reclosure time of pass.In order to avoid block switch not yet disconnects during circuit successful reclosing, trouble point is directly coincided with.Use special test
The present apparatus is connected by cable with block switch, terminal, and after switch separating brake terminates, the time shown on cumulative timer is switch separating brake
Time.
When carrying out logic testing using segmentation terminal logic test device, cumulative timer can record switch opening time automatically
Be worth (cumulative timer operation principle, there is two groups of electric shocks, starts contact and pause contact, when starting the 2 points of connections in contact, for a long time thereon
Device can be automatically into time status, and when suspending contacting, cumulative timer shows numerical value automatically into halted state, next time
Meeting automatic clear restarts when restarting) (block switch auxiliary contact are switch internal indicating contacts, and switch aids in when closing position
Contact is also connected, and contact is opened when switch divides position).Time is accurate to 0.01S, and the time is circuit decompression to switching auxiliary contact
Time used in opening.
Peak switching current test is carried out, in block switch making process, records the maximum current during this automatically
Value, if the maximum current value meets the capacity requirement of closing relay and insurance, peak switching current test is normal;Switch exists
In making process, crest ammeter can record the maximum current during this automatically.
Digital & analog signal subtest is carried out, by changing the state of analog switch, the combined floodgate situation of block switch is observed, sentences
The correctness of disconnected digital & analog signal function.
When entering line delay and closing logic testing, as shown in Fig. 1, Fig. 4 and Figure 11, (voltage-time type distribution is whole for segmentation terminal
End) mains side has a pressure, and terminal delay closes (the specific time can voluntarily be set, and this explanation is by taking X time limits 7s as an example), and setting is " during X
The time of limit test " time relay sj 4 is 5 minutes, closes " general supply " and is spaced apart G1, G2, presses " mains side startup " button
QA1, block switch indicator lamp T3 is observed, if block switch time-delay closing, terminal locking lamp (terminal device carries) does not work, explanation
It is normal that terminal delay closes logic.
When carrying out X time limits locking test, as shown in Fig. 1, Fig. 5 and Figure 11, terminal X time limit interior powers side dead electricity, now eventually
Locking is held, caller terminal delay closes mains side again;Load side caller terminal keeps locking, and switch does not close a floodgate.
It is 5 minutes to set the time of " the X time limits tests " time relay sj 4, during " first time reclosing " time relay sj 1
Between be 2s, the time of " output time after coincidence " time relay sj 2 is 5s, the time of " second of reclosing " time relay sj 3
For 2s, turning on the power, press " mains side startup " button QA1, tester " mains side voltage " indicator lamp T1 is bright (in Fig. 2), etc.
" failure generation " button TA1 is pressed after block switch combined floodgate 5s, block switch indicator lamp T3 (in Figure 11) extinguishes, by about
16s or so block switch indicator lamps brighten, and observation terminal locking lamp is changed into often bright and be changed into extinguishing from extinguishing, then X latching logics
Normally.
When carrying out the test of both sides voltage blocking, as shown in figures 1 to 6, to prevent maloperation, block switch both sides are come simultaneously
Terminal locking is pressed in pressure, Terminal Design both sides voltage blocking functions, both sides simultaneously, and block switch does not close a floodgate, and ensures distribution peace
Row for the national games.
Start " general supply " and be spaced apart G1, G2, starting device, press " mains side startup " button QA1, and press rapidly " negative
Lotus side starts " button QA2, observation segmentation terminal locking lamp is changed into Chang Liang, and block switch indicator lamp do not worked, then terminal both sides are pressed
Latching logic is normal.
It is to determine whether accident, terminal meeting after switch combined floodgate as shown in Figure 1 and Figure 7 when carrying out Y time limits locking test
When carrying out Y quantum clocks, if decompression in the Y time limits, terminal locking lantern festival Chang Liang, mains side carrys out electric switch again to close a floodgate, load
Side carrys out electric switch and can be delayed to close.
It is 5 minutes to set the time of " the X time limits test " time relay sj 4, the time of " single shot reclosing " time relay sj 1
For 2s, the time of " output time after coincidence " time relay sj 2 is 8s, and the time of " second of reclosing " time relay sj 3 is
2s, turn on the power, press " mains side startup " button QA1, tester " mains side voltage " indicator lamp T1 is bright (in Fig. 2), decile
" failure generation " button TA1 is pressed after Duan Kaiguan combined floodgates 5s, block switch indicator lamp and terminal are observed, if block switch indicator lamp
It experienced point, the action process of splitting or integrating, terminal locking lamp is changed into Chang Liang from extinguishing, then is proving terminal Y time limits latching logic just
Often.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
