The utility model discloses a portable latching electromagnet unlocking device, comprising a box body the interior of which is provided with a circuit board, wherein the circuit board in the box body is provided with a voltage regulating circuit, the box body is provided with a plug and/or jack which is externally connected with 220V alternating current, a power supply switch, a voltage regulating knob and an alternating current output jack which outputs power to a latching electromagnet. According to the portable latching electromagnet unlocking device disclosed by the utility model, a working power supply is provided for the latching electromagnet of a handcart breaker by adopting a manner of an externally-connected power supply, and the latching electromagnet is automatically unlocked, and thus the defects of high work load and unsafety caused by manual unlocking can be avoided; and the portable latching electromagnet unlocking device is convenient to carry, and electricity is convenient to take in site.
Description
Technical field
The utility model relates to a kind of device that latching electromagnet locking in the handcart circuit breaker is removed in electric power system that is used for, and relates to a kind of portable latching electromagnet tripper specifically.
Background technology
At present, the handcart circuit breaker in the mesolow application on power system more and more widely, and latching electromagnet all is equipped with in most of handcart breaker mechanisms inside, like the closing locking electromagnet, shakes and into shakes out latching electromagnet or the like.These latching electromagnets not only have mechanical blocking function to mechanism when not controlling power supply, also have the electric blocking function.These equipment are being overhauled or during Installation and Debugging; Because handcart circuit breaker power supply is disconnected; If need operation handcart circuit breaker, general way is to remove mechanism's panel or shell earlier, electromagnet core jack-up is come the machinery or the electric blocking of unlocking electromagnet with hand or screwdriver etc.This method has not only strengthened staff's workload, brings great inconvenience for maintenance and commissioning staff, and simultaneously, when breaker operator, spring energy discharges, and the mechanism part quick acting causes mechanical damage to human body easily.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and a kind of portable latching electromagnet tripper is provided, and can utilize other on-the-spot power supply, makes the release of latching electromagnet automatic electric, with the big and unsafe shortcoming of the workload of avoiding manual release to bring.
The technical scheme that the utility model solves the problems of the technologies described above is: the box body that comprises the set inside circuit board; The 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.During use, connect the 220V alternating current, be electrically connected with the alternating current output plughole with two terminals of lead with latching electromagnet; Adjusting pressuring knob is transferred to setting output voltage position, turns on the power switch again, can make latching electromagnet obtain required electric current; Do not need manual operation, get final product automatic unlocking.
Consider under the electric power system practical situations; Most of handcart circuit breaker locking electromagnet adopt DC power supply; A preferred version of the utility model is: also be provided with the dc output circuit of being made up of current rectifying and wave filtering circuit on the circuit board; Box body is provided with the direct current output plughole to the latching electromagnet out-put supply, and interchange, direct current output switch.Through selecting the direct current output plughole can obtain the required DC power supply of latching electromagnet.
The utility model provides required working power through the mode that adopts external power supply to handcart circuit breaker locking electromagnet, makes its automatic unlocking, thus the big and unsafe shortcoming of the workload of avoiding manual release to bring; And this device is convenient for carrying, and on-the-spot power taking is convenient.
