Abstract

The utility relates to accessory parts of electric current mutual inductor, more specificly a chucking cover for preventing electric larceny. It is to solve the problem existing wiring terminal have not protection device. The chucking cover is composed of two semi-closed chucking covers one of which is mounted with convex cavity at front end. The engaging part of two semi-closed chucking covers has lead-seal hole. The utility can seal all of the wiring terminal of current mutual inductor. The seal is openable when checking, and be closed with lead after checking which render the inductor a anti-theft gate, and can suppress the theft from wiring terminal. The present utility increase a anti-theft device for current mutual inductor which is not existing.

Description

The anti-electricity-theft protection card cover of current transformer

Technical field

The utility model relates to a kind of appurtenances of current transformer, is specially the anti-electricity-theft protection card cover of current transformer.

Background technology

Power supply department adds in the comprehensive wiring metering method of current transformer at three-phase and four-line, adopts current transformer in large quantities.Unprotect device on the binding post of these current transformers, binding post all is in naked state.Like this, wet weather produces electro-chemical reaction, produces cupric oxide, iron oxide on binding post, forms black and solidifies dirt, and resistance is increased, and voltage reduces, and causes measuring misalignment; And binding post is exposed that the stealing lawless person is had an opportunity to take advantage of, and causes power resource to run off in a large number, makes the low-voltage circuit loss, and economic loss is inestimable.

Summary of the invention

The utility model solves the problem of the binding post unprotect device of existing current transformer, provides a kind of current transformer anti-electricity-theft protection card cover.

The utility model is to adopt following technical scheme to realize: the anti-electricity-theft protection card cover of current transformer; two semi-closed card covers by mutual clamping constitute; the front end face of one of them semi-closed card cover is provided with the evagination cavity, and the access section of two semi-closed card covers is provided with lead seal hole.Two semi-closed card covers are connected in the current transformer bottom, the evagination cavity is covered on the binding post, lead seal hole lead sealing seal.Thereby realize protection to the current transformer binding post.

The anti-electricity-theft protection card cover of current transformer described in the utility model can all seal the binding post of current transformer; can open during inspection; can close and use the lead sealing seal after the inspection; increased antitheft door one to current transformer, can effectively contain, guaranteed the normal operation of electric current metering simultaneously from the stealing of current transformer binding post; having filled up current transformer does not have the blank of stealing protective device; protected circuit unimpeded effectively, metering accurately, increase energy benefit.

Embodiment

The anti-electricity-theft protection card cover of current transformer is made of two semi-closed card covers 1,2 of mutual clamping, and the access section that the front end face of one of them semi-closed card cover is provided with evagination cavity 3, two semi-closed card covers is provided with lead seal hole 4.A semi-closed card cover is provided with card key 5, and another semi-closed card cover is provided with draw-in groove 6, and the cooperation by card key, draw-in groove realizes the clamping between two semi-closed card covers.Evagination cavity 3 is hemispherical, like this can be better matches with binding post on the current transformer.Have out line groove hole 7 in the bottom of evagination cavity 3, the line on the current transformer binding post can easily go out line groove hole from this draws, and makes this card cover use more convenient.This card cover selects for use premium insulation, fire proofing casting to form.
