Abstract

The utility model relates to an insulating protective cover for an outgoing line terminal of a power transformer, which is characterized in that the insulating protective cover is an elastic shell cover made of an insulating material, and comprises an insulator cover and a wiring clip cover, wherein an inner cavity of the shell cover is adaptive to shapes of an insulator at the outgoing line terminal and a wiring clip, the shell cover is provided with an incoming line port and longitudinally provided with an opening, and two sides of the opening are movably connected with each other through a lock catch. When the insulating protective cover is used, the protective cover is covered on the insulator at the outgoing line terminal of the transformer and the wiring clip to realize the insulation sealing of the wiring clip. The insulating protective cover can effectively preclude ionization corrosion, and short circuit and damage phenomena of the transformer and personal shock and casualty accidents caused by damage by an high-altitude falling object and the like, and is simple in structure and convenient to use.

Description

Power transformer leading-out terminal insulation protective hood

Technical field

The utility model relates to a kind of power transformer annex, particularly a kind of power transformer leading-out terminal insulation protective hood.

Background technology

At present, the current-carrying part of power transformer leading-out terminal is for exposed, and majority is in open-air operation down, and the ionization corrosion takes place easily, the equipment that outside destroy such as falling object from high altitude, toy causes, human casualty accident are also very serious, but also do not have effective protector in the prior art.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned weak point, and provide a kind of ionization burn into of stopping effectively to damage phenomenon and personal electric shock casualty accident owing to outside destroy such as falling object from high altitude cause transformer short-circuit, power transformer leading-out terminal insulation protective hood simple in structure, easy to use.

The purpose of this utility model is achieved in that a kind of power transformer leading-out terminal insulation protective hood, it is characterized in that it is an elasticity clamshell by the insulating material making, comprise insulator cover, wiring wire clamp cover, the insulator of clamshell inner chamber and leading-out terminal, wiring wire clamp profile are suitable, the inlet wire port is arranged on the clamshell, vertically opening is arranged, the opening both sides are flexibly connected by snap close.

The utility model is owing to adopt above design, during use, this protective cover is covered on the insulator, wiring wire clamp of transformer leading-out terminal, the butted line wire clamp carries out insulated enclosure, the ionization burn into be can effectively stop and phenomenon and personal electric shock casualty accident damaged owing to outside destroy such as falling object from high altitude cause transformer short-circuit, simple in structure, easy to use.
