Abstract
The invention relates to the field of voltage transformers, in particular to a rainproof type current transformer. The rainproof type current transformer comprises a current transformer box, a transformer body and porcelain bushings. Hooks are arranged on the lower portion of the current transformer box, the transformer body is of a U-type structure, the lower portion of the transformer body is arranged in the current transformer box, and the upper portions of the transformer body extend out of the current transformer box. The outer surfaces of the extending-out portions are sleeved with the porcelain bushings, primary wiring terminals are arranged at the upper ends of the extending-out portions, and conductive clamps are connected to the primary wiring terminals. The rainproof type current transformer is characterized by further comprising a rainproof cover, the rainproof cover is a groove-shaped piece in a U shape, connecting through holes are formed in the bottoms of the two vertical edges, and the rainproof cover covers the primary wiring terminals and the conductive clamps and is fixedly connected with the transformer body through the connecting through holes. The primary wiring terminals and the conductive clamps are covered with the rainproof cover and prevented from being eroded by rainwater, the measuring accuracy of the rainproof type current transformer is guaranteed, the service life of the rainproof type current transformer is prolonged, and meanwhile potential safety hazards are eliminated.
Description
Technical field
The present invention relates to voltage transformer field, specifically a kind of rain proof type current transformer.
Background technology
Outdoor voltage transformer is measuring voltage in electric power system, the equipment of electric energy or relaying protection, especially pushing forward comprehensively along with national distribution automation work, various intelligent outdoor pole top switchs and demarcation switch adopt in a large number, outer through wind owing to being exposed to throughout the year, rain erosion, make the binding post on current transformer and the parts such as clip that conduct electricity be subject to damage in various degree, it is accurate that impact is measured, increase failure rate, there is certain potential safety hazard, when serious, even there is the short circuit of current transformer generation internal structure, explosion, device security and personal safety are caused
Threaten.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of rain proof type current transformer is provided.
Technical scheme of the present invention is: a kind of rain proof type current transformer, comprise current transformer casing, device body, insulator, described current transformer casing bottom is provided with hook, and described device is as " U " shape structure, its underpart is placed in described current transformer casing, and described casing is stretched out on top; Its extension appearance surface cover has insulator, upper end is provided with primary connection terminal, on described primary connection terminal, be connected with conduction clip, it is characterized in that: also comprise rain cover, described rain cover is for having the channel of " U " shape shape, two vertical edges bottoms are provided with connecting through hole, and described rain cover covers on terminal and conduction clip top, by described connecting through hole and described device body, is connected and fixed.
Further, also comprise reinforcement, described rain cover inside is provided with reinforcement.
Beneficial effect of the present invention: adopt rain cover that primary connection terminal and conduction clip are covered, avoided it to be subject to rain erosion, guaranteed the accurate and useful life of current transformer metering, eliminate safe hidden trouble simultaneously.
