The portable unlocking device comprises a box body in which a circuit board is arranged, wherein a voltage regulation circuit is arranged on the circuit board in the box body; and a plug and/or an insertion hole which are or is externally connected with 220V alternating current, a power supply switch, a voltage regulation knob and an alternating current output insertion hole for outputting power supply to the latching electromagnet are arranged on the box body. The circuit board is also provided with a direct current output circuit formed by rectification filtering circuits. The box body is provided with a direct current output insertion hole for outputting power supply to the latching electromagnet, and alternating current and direct current output switches. A connection terminal of the latching electromagnet is electrically connected to the power supply output insertion hole of the portable unlocking device by wires, thus the latching electromagnet can be unlocked. In the portable unlocking device, required working power supply is supplied to the latching electromagnet of a circuit breaker of a hand trolley by adopting an external power supply to unlock the latching electromagnet automatically, so the shortcomings of large working quantity and unsafety caused by manual unlocking can be overcome; furthermore, the device is portable and can take electricity conveniently on site.
Description
Technical field
The present invention relates to a kind of installation method of removing latching electromagnet locking in handcart circuit breaker for electric power system, specifically a kind of method of utilizing the release of portable tripper rival car circuit breaker lock electromagnet.
Background technology
At present, the application of handcart circuit breaker in mesolow electric power system is more and more extensive, and the in-house latching electromagnet that is all equipped with of most of handcart circuit breaker, as: closing locking electromagnet, shakes into shaking out latching electromagnet etc.These latching electromagnets, when not controlling power supply, not only have mechanical blocking function to mechanism, also have electric blocking function.These equipment are being overhauled or during Installation and Debugging, because handcart circuit breaker power supply is disconnected, if desired operate handcart circuit breaker, general way is first to remove mechanism's panel or shell, with hand or screwdriver etc., electromagnet core jack-up is come to machinery or the electric blocking of unlocking electromagnet.This method has not only strengthened staff's workload, brings great inconvenience to maintenance and commissioning staff, and meanwhile, when breaker operator, spring energy discharges, and mechanism components quick acting, easily causes mechanical damage to human body.
Summary of the invention
The object of the invention is for the problems referred to above, a kind of method of utilizing the release of portable tripper rival car circuit breaker lock electromagnet is provided, can utilize other on-the-spot power supply, make the release of latching electromagnet automatic electric, large and unsafe shortcoming with the workload of avoiding manual release to bring.
The technical scheme that the present invention solves the problems of the technologies described above is: described portable tripper comprises that inside arranges the box body of circuit board, box body interior circuit board is provided with regulating circuit, the plug that box body is provided with external 220V alternating current and/jack, mains switch, adjusting pressuring knob and to the output plughole that exchanges of latching electromagnet out-put supply; Its unlock method is as follows:
Plug or jack are connected 220V alternating current, two other ends are inserted respectively to two direct current output plugholes with wire one end of wire clamp or exchange in output plughole, the wire other end is clipped in respectively direct current or exchanges on the binding post of latching electromagnet, turn on the power switch, by adjusting pressuring knob, adjust after output voltage, press direct current output switch or exchange output switch, realizing latching electromagnet release.Do not need manual operation, get final product automatic unlocking.
Consider under electric power system practical situations, most of handcart circuit breaker latching electromagnets adopt DC power supply, on foregoing circuit plate, be also provided with the DC output circuit being formed by current rectifying and wave filtering circuit, box body is provided with the direct current output plughole to latching electromagnet out-put supply, and interchange, direct current output switch.By selecting direct current output plughole can obtain the required DC power supply of latching electromagnet.
The present invention, by adopting the mode of external power supply to provide required working power to handcart circuit breaker latching electromagnet, make its automatic unlocking, thereby the workload of avoiding manual release to bring is large and unsafe shortcoming; And this device is convenient for carrying, on-the-spot power taking is convenient.
