Description

Enclosed busbar is connected wire box with transformer connecting terminal

Technical field

The utility model belongs to the electric power accessory, and particularly a kind of enclosed busbar is connected wire box with transformer connecting terminal.

Background technology

In enclosed busbar and transformer connecting terminal syndeton, because the transformer connecting terminal phase spacing is smaller, the connector of enclosed busbar and such transformer connecting terminal syndeton is usually exposed in air, so just easily connector often is exposed to the elements, the corrosion of airborne harmful substance in addition, be easy to shorten the life-span of connector, cause connector fragile, affect whole electric power netting safe running.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides enclosed busbar a kind of simple in structure, easy for installation, safe and reliable to be connected wire box with transformer connecting terminal.

The technical scheme that the utility model technical solution problem adopts is: enclosed busbar is connected wire box with transformer connecting terminal and comprises transformer, transformer connecting terminal, the transition gold utensil, copper litz wire, enclosed busbar outlet gold utensil, go out into case rising seat, rubber bellows, the enclosed busbar conductor, the enclosed busbar shell, be characterized in three wire boxs raise seat below be provided with a wire box casing, on wire box box inside face, the position of corresponding three wire boxs rising seat is respectively equipped with three manholes, manhole cover is housed respectively on manhole, manhole cover is fixed on the wire box casing by the manhole cover fixture respectively, transformer connecting terminal, the transition gold utensil, copper litz wire, enclosed busbar outlet gold utensil all is placed in the wire box casing, the enclosed busbar outlet gold utensil be connected with the enclosed busbar conductor is connected respectively an end of copper litz wire, the other end of copper litz wire connects respectively the transition gold utensil, the transition gold utensil is the connection transformer binding post respectively, and the enclosed busbar shell passes through rubber bellows, wire box rising seat is connected with the wire box casing, and the wire box casing is fastened on transformer by wire box adpting flange and transformer flange.

The beneficial effects of the utility model are: enclosed busbar is connected the wire box reasonable in design with transformer connecting terminal, performance safety is reliable, the convenient installation, the transformer connecting terminal that can make enclosed busbar be connected with transformer, the transition gold utensil, copper litz wire, enclosed busbar outlet gold utensil all is placed in the wire box casing, make them avoid exposing to wind and rain and the infringement of Exposure to Sunlight, avoid the corrosion of harmful substance in air, increase the service life to greatest extent, save operating cost, the wire box body structure is good to the shield effectiveness in magnetic field simultaneously, can reduce the eddy current loss of equipment, these all are conducive to the safe and stable operation of electrical network.
