Description
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
