Abstract
This utility model relates to a maintenance-free dewing current transformer, comprising a primary coil, a secondary coil, and an iron core, the primary coil is winded into a circle one side of which passes through the iron core, the secondary coil winds evenly on the iron core which comprises iron chips winded into circles; and this utility model meets the requirement of partial discharging performance, high accuracy, dewing type and all-weather.
Description
Technical field
The utility model relates to a kind of current transformer.
Technical background
The penetration type chain current transformer of power industry use at present mostly adopts square laminated core, semi-closed structure.This current transformer core and secondary winding expose, and secondary winding is few, and capacity is little, are subjected to the influence of wet environment easily, also can get rusty when serious or secondary winding is punctured, and the partial discharge performance can not meet the demands.
Summary of the invention
The purpose of this utility model provides that a kind of partial discharge performance is good, high accuracy, condensation type, many windings, big capacity, non-maintaining current transformer.
For achieving the above object, the utility model adopts following technical scheme:
Non-maintaining condensation type current transformer described in the utility model comprises primary winding, secondary coil, iron core, primary winding coiled ring-type, and the one side is passed iron core, and the secondary coil uniform winding is on iron core, and iron core is made of the lamination that is wound into ring-type.
Iron core is preferably by 2---and 3 lamination arrangements that are wound into ring-type form.
Secondary coil can have 2---3 windings.
This non-maintaining condensation type current transformer, its outer surface has the epoxy resin mixed glue solidfied material.
Its internal air gap of lamination that is wound into ring-type is less than laminated core, and the partial discharge performance of annular core is better than square iron core, and the secondary coil winding is many, capacity is big; The epoxy resin mixed glue solidfied material of outside can be protected the inner interference that is not subjected to moisture vapor effectively.
Description of drawings
Accompanying drawing is the half sectional view of an embodiment of the present utility model.
