Abstract

The utility model discloses a secondary circuit wiring terminal strip short-circuiting plug for a power plant or a transformer station. The plug comprises an insulating seat and a plurality of pins arranged on the insulating seat. The insulating seat is internally provided with a conductive connector which is connected with the plurality of pins. According to the utility model, the purpose of short-circuiting a secondary current measuring circuit of a power plant or a transformer station is effectively achieved by just plugging the short-circuiting plug into a short-circuiting socket of the wiring terminals, and the phase-by-phase copper wire short-circuiting method in the prior art is replaced by short-circuiting the plurality of terminals of the secondary current circuit all at once by the plug, thereby greatly saving work time and increasing the work efficiency; besides, the insulating seat greatly ensures the safety and reliability of the operation, and effectively ensures the safety of electric equipment and operators. The secondary circuit wiring terminal strip short-circuiting plug provided by the utility model has the advantages of simplicity, practicality and low cost, and is capable of effectively short-circuiting the secondary current circuit with high speed and safety, being valuable for wide popularization.

Description

Power plant, Substation secondary circuit connecting terminal block short circuit plug
Technical field
The utility model relates to electrical power wiring apparatus for examination and repair technical field, relates in particular to a kind of power plant, Substation secondary circuit connecting terminal block short circuit plug.
Background technology
Binding post is indispensable accessory in power plant, the wiring of secondary current loop of transforming plant electric current, and in screen, equipment is realized with shielding being connected by terminal and cable between external equipment, and many terminal combination form terminal board together.
Power plant, substation relay protection and automatics and power supply metering, must make Current Transformer that large electric current is once become to the little electric current of secondary by a certain percentage, resupplies electric measurement and relaying protection and automatics use.Current transformer belongs to the category of special transformer, its operating state is equivalent to the short circuit operation of transformer, therefore do not allow secondary coil two ends open circuit, if there is open loop state, except producing too high induced voltage, cause outside equipment and personal danger, also increasing due to magnetic flux density, loss increases, and it is unshakable in one's determination overheated and cause that instrument transformer damages to cause.
When secondary current measuring circuit carries out routine inspection or other situation operations every year, conventionally adopt screwdriver to back out the small screw on terminal board, with annealed copper wire, will after the three-phase short-circuit of terminals, tighten housing pin respectively again, the problem that this process is prone to is most, after small screw is loosening with bottleneck screwdriver, easily come off in the rear underground gap of screen, be difficult for finding, the process of short circuit will take the considerable operating time.Sometimes staff is for catching up with the operating time, and the method that often adopts annealed copper wire to be wound around is carried out short circuit, if poor short circuit causes major safety risks will to the operation of equipment.
Authorizing disclosed application number on January 2nd, 2013 is that 201220326646.5 utility model patent discloses the quick short-circuit device of a kind of Current Transformer Secondary side, by stiff end and the earth connection that is connected with stiff end, formed, stiff end is connected in parallel on earth connection by wire, earth connection one end ground connection.Described stiff end can be the clip of conduction, can be also magnet, can also be short circuit fixture.Its weak point is: complex structure, and lack insulating mechanism, be not suitable for the short circuit operation of power plant, secondary current loop of transforming plant, there is serious potential safety hazard, easily damage equipment, testing staff is caused to unnecessary injury.
