Relay 22 and protector 5, protector 5, the power cut off delay type time relay 1, main contactor 3 and auxiliary reclay 22 depend on
Secondary it is connected in series；Auxiliary reclay one 7(ZJ-1 it is provided with in vacuum starter 1), the power cut off delay type time relay 26 connects
The lower end of the normally opened point of auxiliary reclay 1.Protector 5 uses JDB-80 protector.
As shown in Figures 2 and 3, the power cut off delay type time relay 26 include 1# line, 8# line, commutator 8, electric capacity 1,
Electric capacity 2 10, resistance 11 and miniature intermediate relay 12(MY2NJ), commutator 8 two ends connect 1# line and 8# line, commutator 8 points
Lian Jie electric capacity one 9(C1), electric capacity two 10(C2) and resistance 11(R), resistance 11 and miniature intermediate relay 12 are connected in series, whole
Stream device 8 forms parallel circuit with electric capacity 1, electric capacity 2 10 1 resistance 11 and miniature intermediate relay 12.Miniature intermediate relay
12 use MY2N miniature intermediate relay.The input of the power cut off delay type time relay 26 is 1# line and 8# line, 1# line and 8#
Line is the control end of the power cut off delay type time relay 26.4# line, 5# line it is provided with in the power cut off delay type time relay 26
With 6# line, 4# line is common port, and 4# line and 5# line are a pair normally-closed contact, and 4# line and 6# line are a pair normally opened contact.Power-off is prolonged
Time the 4# line of the type time relay 26 and the normally-closed contact of 5# line be serially connected in 33# detection line on, it is achieved the protection to protector.
The DSJ type power cut off delay type time relay 26 surface structure is as the ST3PF power cut off delay time relay, sharp
Use existing shell, inside wiring board and following several original paper to be made, be fixed on PF083A-E relay base
On QBZ 80 vacuum starter 1 insulation board.Wherein, the size of electric capacity 1 and electric capacity 2 10 is 470uf250V, the resistance of resistance 11
Value is 1500 Ω, and MY2NJ miniature intermediate relay 12 uses Omron DC24V mono-to open one and closes.
According to as a example by QBZ 80 vacuum starter 1 that Xuzhou Coal Mine Machinery Factory produces, the DSJ type power cut off delay type time continues
Electrical equipment 26 is as follows in QBZ 80 vacuum starter 1 wiring: the DSJ power cut off delay type time relay 26 pull-in winding 1# line connects
On QBZ 80 vacuum starter 1 9# line, it is normal that 8# line is connected on QBZ 80 vacuum starter 1 auxiliary reclay 1 ZJ-1
The lower end made war.Power cut off delay Guan Bi contact 4# and 5# of the DSJ power cut off delay type time relay 26, is serially connected in 33#
On detection line.
Specific works mode: QBZ 80 vacuum starter 1 closes HGK disconnecting switch, 660/36V transformator output 36V electricity
Pressure, equipment is detected by JDB protector 5, and after determining that equipment is normal, JDB protector 5 internal relay action normally opened contact closes
Close, start for QBZ 80 vacuum starter 1 and carry out path preparation.Press start button auxiliary reclay 1 coil and obtain electric suction
Closing, the normally opened contact ZJ-1 Guan Bi of auxiliary reclay 1, the power cut off delay type time relay 26 obtains electric adhesive, electric capacity 1 He
Electric capacity 29 charges, the power cut off delay type time relay 26 action, goes here and there and detects the middle relay on line at JDB protector 5 33#
Device 22, main contactor 3, the normally closed point of the power cut off delay type time relay 1 are normally opened, and main contactor 3 coil obtains electric adhesive simultaneously,
QBZ 80 vacuum starter 1 starts, and equipment runs well.Auxiliary reclay 22, main contactor 3 line when pressing stop button
Circle dead electricity switch stops, and vacuum contactor 1 disconnects, when the normally opened contact of auxiliary reclay 1 ZJ-1 disconnects, and at this moment power-off
Delay type time relay 26 non-transformer inputs, and electric capacity 1 and electric capacity 29 utilize the feature of capacitor charge and discharge to start electric discharge, disconnected
Electricity delay type time relay 26 coil continues to obtain voltage, continues to attracting state, and the normally closed point of power cut off delay is all the time disconnected
Do not close under electricity delay type time relay 26 attracting state, go here and there and detect the power cut off delay type time relay 26 on line at 33#
Normally closed point do not close, now electric capacity works on, main contactor 3 stop time produce overvoltage sponge.Work as electric capacity
One 8 and after electric capacity 29 discharges voltage completely, the power cut off delay type time relay 26 discharges, power cut off delay type time relay
The normally closed Guan Bi of power cut off delay of device 26 line, thus JDB protector 5 is played a protective role.
