Description

A kind of ring main unit 10kV miniaturization threephase potential transformers
Technical field
The utility model is related to a kind of ring main unit 10kV to minimize threephase potential transformer, and in particular to a kind of 12kV and The measuring electromagnetic potential transformer of 12kV or less voltage class belongs to electric instrument and ring main unit high voltage equipment neck Domain.
Background technology
At present, conventional voltage transformer is put into ring main unit, since mutual inductor does not live a high pressure sealing, and Ring main unit space is not achieved cabinet insulation distance, is easy to bring security risk to people and instrument and meter again than narrow.
The existing ring main unit voltage transformer silicon steel sheet common since iron core is all made of, core sataration flux density is low, from And the mutual inductor shape made is larger, cannot be mounted in very narrow ring main unit.
Utility model content
The utility model provides a kind of ring main unit 10kV miniaturizations threephase potential transformer, realizes miniaturization, can It is widely used in any switchgear.
The utility model solves above-mentioned technical problem by following technological means:
A kind of ring main unit of the utility model minimizes threephase potential transformer with 10kV comprising iron core, the iron core On be wound with secondary line and primary line, primary line is connect by a connection inserting part with fuse, and fuse and cable plug connect It connects and draws, wiring bent plate is provided with beside the cable plug, iron core is cast in cast together with secondary line and primary line In vivo, the secondary line is connect with secondary terminals, is equipped with anti-electricity-theft seal closure on secondary terminals, on the anti-electricity-theft seal closure It is provided with secondary fastening nut.
Its bottom is provided with pedestal.
The iron core is R shaped iron cores.
Connection inserting part carries elbow head, and insulating sleeve, fuse and secondary line and one are provided with outside fuse Secondary line electrical connection, is equipped with elbow-type end, elbow-type end is electrically connected with fuse on insulating sleeve.
This product is that the high-pressure side completely newly developed carries the V/V type wiring threephase potential transformers of fuse protection, once Terminal is matched with elbow head with American 200A elbow plugs, and fuse, fuse and inner wire are equipped in insulating sleeve Circle electrical connection, is equipped with elbow-type end, elbow-type end is electrically connected with fuse on insulating sleeve.This product iron core uses Import R shaped iron cores, this type core area can maximize, i.e., the effective area of iron core is maximum, another this shaped iron core magnetic saturation Ability is strong, so the mutual inductor shape that can make in the case of equivalent parameters minimizes, in addition this product outer surface is also tangible, right It is safe and reliable for people and equipment.Product meets GB20840 and IEC《Voltage transformer》Standard.
The utility model voltage transformer is equipped with elbow-type end on insulating sleeve, changes traditional voltage and once goes out Line, and insulating sleeve is built-in with changeable type fuse reduces the volume of voltage transformer without additionally mounted;It can use In narrow ring main unit.This mutual inductor, can also be with operation power 220V output electricity other than secondary output 100V is for measuring Pressure side makees power supply for operating mechanism, can be widely used in any switchgear, is optimal renewal product.
The beneficial effects of the utility model:A kind of ring main unit of the utility model minimizes three-phase voltage mutual inductance with 10kV Device realizes miniaturization, can be widely used in any switchgear.
