Description

A kind of transformator supplies power with double circuit distribution box

Technical field

This utility model relates to a kind of power supply unit, in particulars relate to a kind of power transformer and supplies power with double circuit distribution box.

Background technology

Matched transformer electronic box is a kind of conventional power supply device, and it collects distribution, measures, protects and reactive-load compensation is in one Body, has become the controller switching equipment that outdoor transformer user is main, owing to this distribution box is usually attached under transformator Portion, volume is little, installing element is more, causes the insulation distance of existing many distribution box electric elements not reach standard-required, Simultaneously because space is too small, working service is extremely difficult.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of conventional art, and a kind of volume of design is little, and each electric elements are arranged Rationally, connect up transformator ingenious, easy to maintenance to supply power with double circuit distribution box.

For achieving the above object, this utility model supplies power with double circuit distribution box for a kind of transformator, including Rainproof box body, setting Measuring room on the right side of the load cell, load cell in Rainproof box body front, it is arranged on the disconnecting switch folding room at the Rainproof box body back side With the capacitance compensation room in left side, it is characterized in that: described load cell top arranges disconnecting switch, and bottom arranges load break switch, Bottom is provided with two insulators, arranges a N row on the top of insulator, arranges a ground bottom insulator at body contact body Row, a road power supply of described distribution box from the top inlet wire of disconnecting switch, another road power supply from the bottom inlet wire of disconnecting switch, if Putting the disconnecting switch action cutter leading-out wire busbar in side, described disconnecting switch folding room, described outgoing line busbar is through 90 degree of lower foldings After roll over 90 degree again from disconnecting switch bottom through being connected with load break switch, in described disconnecting switch folding to described load cell On the outgoing line busbar of side, room, metering current mulual inductor is set, the outgoing line busbar of described load cell arranges standby current mutual inductance Device.

Especially, in the distribution box of said structure, described disconnecting switch folding room arranges disconnecting switch plate on front side of top, Disconnecting switch plate is provided with the folding handle socket of disconnecting switch, the bottom of disconnecting switch plate is provided with instrument door, The side of instrument door is provided with dedicated lock, and the disconnecting switch folding room at instrument door rear portion is provided with metering current mulual inductor and institute State the incoming-line busbar of capacitance compensation room, so, after instrument door is shut and locked, in described metering current mulual inductor is locked in, Cannot artificially practise fraud.

The distribution box of above structure has an advantageous effect in that, various electric elements arrange rationally in distribution box, female Line configuration path is short and specification, and metering current mulual inductor is not required to increase quarantine measures and can effectively be protected, greatly local Maintenance and management to distribution box.
