The utility model relates to a current mutual inductor, it is fixed simple and convenient, can prevent electric discharge phenomena's between the two adjacent current mutual inductor emergence, improved the insulating properties between the current mutual inductor.
Description
Technical field
The utility model belongs to instrument transformer technical field, specifically, relates to a kind of current transformer.
Background technology
High voltage electric equipment in recent years manufacturing process reaches its maturity, and properties of product are also being updated.But insulation property are bad, ageing resistance is poor shortcoming that partial vacuum circuit breaker still exists.Vacuum circuit-breaker fault mainly appears in built-in current instrument transformer insulation link, and its reason is that insulation quality does not reach the bad and Lightning Over-voltage of requirement, insulating wrapping technique and punctures, and makes switch internal there is partial discharge phenomenon.Wherein serious with the electric discharge phenomena between current transformer again.Current transformer lay out in parallel, between two adjacent current transformer high pressure connections, insulation property are low bad, very easily electric discharge phenomena occur.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of current transformer, can prevent the generation of electric discharge phenomena between adjacent two current transformers, improve the insulation property between current transformer.
The utility model object is achieved in that a kind of current transformer, comprise transformer casing, its key is: described transformer casing top arranges high-voltage terminal, the bottom of this transformer casing sidewall arranges low voltage terminal, the both sides of this high-voltage terminal are respectively equipped with baffle plate, this baffle plate is perpendicular to transformer casing end face, and the described baffle plate of both sides is symmetrical arranged, and the sidewall of described transformer casing is provided with at least 2 circle shirt rims.
During current transformer lay out in parallel, easily there are electric discharge phenomena in the high-voltage terminal between adjacent two current transformers, adopt said structure, baffle plate can by the high-voltage terminal isolation between adjacent current transformer, prevent from, between adjacent current transformer, electric discharge phenomena occur, and shirt rim can lengthen along face creepage distance.
Above-mentioned baffle plate has 2n block at least, described n be greater than 0 positive integer, described baffle plate be arranged in parallel, and the described baffle plate being positioned at high-voltage terminal both sides is symmetrical arranged between two.
Adopt said structure, polylith baffle plate can improve insulation property further, increases the difficulty that electric discharge occurs further.
The both ends of the surface of above-mentioned baffle plate flush with the edge of described transformer casing end face respectively.
Adopt said structure, stretching baffle plate taken up space, and prevents electric discharge phenomena from occurring from the two ends of baffle plate.
Between the described baffle plate of two symmetries of inner side, be connected with two pieces of blocks, two pieces of described blocks are symmetricly set on the two ends of baffle plate.
Adopt said structure, block can prevent from, from the electric discharge of baffle plate two ends, further increasing insulation property.
Above-mentioned shirt rim comprises the shirt rim, top being positioned at transformer casing highest point and the common shirt rim being positioned at below shirt rim, top, and the thickness of shirt rim, described top is greater than the thickness of common shirt rim.
Adopt said structure, the shirt rim arranged can lengthen the distance creepage along face, but shirt rim generally arranges thinner, and when a dead lift current transformer, generally carry in the shirt rim of highest point by holding, very easily shirt rim, top is removed bad, therefore the shirt rim, top of highest point is thickeied, prevent carrying from damaging.
Beneficial effect:
A kind of current transformer of the utility model, fixing simple and convenient, the generation of electric discharge phenomena between adjacent two current transformers can be prevented, improve the insulation property between current transformer.
Accompanying drawing explanation
