Abstract

The utility model relates to a 10KV distributing transformer connecting rod insulating cover, comprising a high-tension wiring terminal insulating cover and a low-tension wiring terminal insulating cover which are made of insulating materials, the inner chambers of the high-tension wiring terminal insulating cover and the low-tension wiring terminal insulating cover are respectively fit with the outer shapes of a high-tension wiring terminal and a low-tension wiring terminal, the side and the bottom surfaces of the inner chambers are provided with corresponding wire inlets and wire outlets, and the low-tension wiring terminal insulating cover is movably connected by a left and a right half clamping sleeves into an entity. The high-tension wiring terminal insulating cover and the low-tension wiring terminal insulating cover are respectively covered on the high-tension wiring terminal and the low-tension wiring terminal of a distributing transformer in use in order to seal and insulate the exposed parts of the wiring terminals and wires led in and out, and the damage of a transformer due to short circuit caused by the destruction of external forces such as high falling objects, etc. and personal casualty due to electric shock are effectively avoided. The utility model has the advantages of simple structure, convenient operation, economy and utility.

Description

10kv distribution transformer binding post insulating cover

The utility model relates to a kind of accessory of distribution transformer, particularly a kind of 10kv distribution transformer binding post insulating cover.

At present, the high and low pressure side of distribution transformer turnover line and binding post current-carrying part are exposed on the 10kv post, the equipment that outside destroy such as falling object from high altitude, toy causes, human casualty accident order become serious, according to statistics, owing to throwing away thing and drop and causing short circuit on the transformer, burning out the coil accident and account for more than 21% of transformer damage accident in the high-altitude, but also there is not effective protector in the prior art.

The purpose of this utility model is in order to overcome above-mentioned weak point, and provide a kind of can effectively stopping to damage phenomenon and personal electric shock casualty accident owing to outside destroy such as falling object from high altitude cause transformer short-circuit, 10kv distribution transformer binding post insulating cover simple in structure, easy to use.

The purpose of this utility model is achieved in that 10kv distribution transformer binding post insulating cover comprises high tension terminal insulating cover, low tension terminal insulating cover.The high tension terminal insulating cover inner chamber and the high tension terminal profile that adopt withstand voltage 30,000 volts of above insulating material to make match, the bottom is that cylindrical shape, top are for conical, outwards outstanding inlet wire pipe is arranged on the cover body upper portion side wall, on the inlet wire pipe external port outer wall chimb is arranged, there is outwards outstanding entrance hole at the sealing cap center that is fastened on the inlet wire pipe external port chimb, and aperture and inlet wire match.The low tension terminal insulating cover inner chamber and the low tension terminal profile that adopt withstand voltage 4000 volts of above insulating material to make match, flexibly connect into flat box-like integral body by its left and right halves cutting ferrule, wire hole is arranged on the front end face, electrical verification hole, bushing shell for transformer hole are arranged on the bottom surface, louvre is arranged on the two sides.

Fig. 1 is a high tension terminal insulating cover outline drawing;

Fig. 2 is a high tension terminal insulating cover cover body cutaway view;

Fig. 3 is a high tension terminal insulating cover sealing cap cutaway view;

Fig. 4 is a low tension terminal insulating cover outline drawing;

Fig. 5 is low tension terminal insulating cover left side half block interior shape figure;

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

10kv distribution transformer binding post insulating cover comprises high tension terminal insulating cover 1, low tension terminal insulating cover 6.High tension terminal insulating cover 1 inner chamber and the high tension terminal profile that adopt silicon rubber to make match, the bottom is that cylindrical shape, top are for conical, outwards outstanding cylindrical shape inlet wire pipe 2 is arranged on the cover body upper portion side wall, on the inlet wire pipe 2 external port outer walls chimb 3 is arranged, there is outwards outstanding entrance hole 5 at sealing cap 4 centers that are fastened on the inlet wire pipe 2 external port chimbs 3, and aperture and inlet wire match.Adopt low tension terminal insulating cover 6 inner chambers and the low tension terminal profile of PP-10 plastic production to match, connect into flat box-like integral body by correspondence card post 9, hole clipping 10 cutting ferrules on

step

7,8 corresponding on its left and right halves end limit and the end limit inwall, wire hole 11 is arranged on the front end face, electrical verification hole 12, bushing shell for transformer hole 13 are arranged on the bottom surface, louvre 14 is arranged on the two sides.

The utility model is owing to adopt above design, during use, this insulating cover is covered on respectively on the high and low pressure binding post of distribution transformer, pairs of posts and turnover line exposed part carry out insulated enclosure, can effectively stop to damage phenomenon and personal electric shock casualty accident owing to outside destroy such as falling object from high altitude cause transformer short-circuit, simple in structure, easy to use, economical and practical.
