Description
Technical field
The utility model relates to a kind of leak(age) test pick-up unit, particularly relates to a kind of distant place leak(age) test detecting device.
Background technology
According to national regulation, to regularly carry out distant place leak(age) test to the down-hole low-voltage power supply system in colliery.Present test method is: in magnetic starter the resistance two ends are connected on respectively between 660V load side and the earth terminal, cover switch cover, press start button, whether observe leakage tripping.Its weak point is a wiring trouble, can only detect leak detection relay or whether the selective leakage feeding switch trips, and can not detect the leakage tripping time.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, provides a kind of easy to operate, whether can detect leakage tripping, can detect the distant place leak(age) test detecting device of leakage tripping time again.
For achieving the above object, the utility model adopts following solution: comprise the flame-proof type housing, on housing, be provided with through wires hole, it is characterized in that: electrical secondmeter, power knob, test button, return-to-zero button are set in housing, the 9V battery is installed in electrical secondmeter, and the 9V battery is formed the loop by electric wire and relay, the power knob of band normal opened contact; Connect electric wire after the one end ground connection of relay normally open contact and stretch out housing from through wires hole, the other end connects electric wire and stretches out housing by test button, resistance from through wires hole; Electrical secondmeter I line connects electric wire and stretches out housing by test button from through wires hole, and the electrical secondmeter ground wire connects electric wire and directly stretches out housing from through wires hole; The return-to-zero line of electrical secondmeter connects the return-to-zero button.
Above-mentioned distant place leak(age) test detecting device, it is characterized in that: described housing is provided with cap, is provided with view window, button hole and button direction board on cap.
Above-mentioned distant place leak(age) test detecting device is characterized in that: described through wires hole is spiral loudspeaker mouth.
Principle of work of the present utility model is: the electric wire that directly stretches out housing after the relay normally open contact one end ground connection of the present utility model is connected on the ground connection screw of magnetic starter wire connection cavity, and the electric wire that passes through test button and resistance that the other end connects is connected on the arbitrary binding post of wire connection cavity 660V; Electrical secondmeter I line and ground wire wire connecting are connected on respectively on the control binding post 13 and 8 of wire connection cavity.When carrying out leak(age) test, at first press power knob K, the contact J of relay
1Closure, electrical secondmeter shows zero-bit; Start magnetic starter, load side gets electric, the auxiliary normal opened contact CKJ closure of vacuum contactor; Press test button SA, the 660V power supply is by resistance R, test button SA, contact J
1Electric leakage ground connection, electrical secondmeter picks up counting simultaneously, electric substation's leak detection relay or selective leakage feeding switch would trip, the magnetic starter dead electricity, CKJ disconnects, whether in time this moment, electrical secondmeter stopped timing, demonstrated the electric leakage time that is grounded to this process of magnetic starter dead electricity from 660V power supply electric leakage, thereby detect leak detection relay or selective leakage feeding switch action message.
Compared with prior art, the utlity model has following advantage:
1, because the utility model can be fixedly connected on the magnetic starter,, avoided testing the trouble that all needs wiring, so the utlity model has easy to operate advantage so that regularly carry out distant place leak(age) test at every turn.
2,, so whether the utility model can detect leakage tripping, can detect the leakage tripping time again, thereby can detect whether in time action message of leak detection relay or selective leakage feeding switch because the utility model is provided with electrical secondmeter.
