Description

A kind of 12kV cable hut

Technical field

The utility model relates to a kind of 12kV cable hut.

Background technology

High voltage cable junction box is a kind of power distribution equipment that supplies, and the switching of extensive use high voltage supply circuit is connected with branch, and the confession Electrical Safety and the saves energy that promote electrical network are played an important role.Cable hut generally uses the even charged plug type cable joint of closed type cable joint at present, this cable joint needs special electric cable accessories, cost is high, and the two-phase that can form in short-term while certain phase cable joint being carried out to plug in simultaneously using is powered and causes accident of power supply.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to install and safe and reliable 12kV cable hut.

For achieving the above object, this cable hut comprises isolating switch, temperature and humidity control device, electrification display, the casing of cable fault indicator and these facilities of installation, described isolating switch comprises insulator, copper busbar terminal, conduction cutter, earthing and conduction cutter, the operator link of earthing, described copper busbar terminal is connected directly with bolt fastening to the Wiring nose of cut cable and copper bar terminal with turnover cable, the insulation of exposed current-carrying part and casing adopts air insulation, on two limits of line cable, the fixing coil holder that insulator is housed is set simultaneously, it is solid in order to line cable is pricked, avoided rocking of cable connecting terminal.When line powering, inlet wire cable is connected with each branch cable each branch line power transmission by conduction cutter, and when circuit carries out interruption maintenance, conduction cutter disconnects, and earthing closes, and makes inlet wire cable and earth connection form path, has guaranteed the maintenance safety of circuit.

Described casing comprises shell and the special door lock with rainproof ceiling and leakproof door, especially, in casing, be also provided with inside door, potential indicator, cable fault indicator and the temperature and humidity controller of electromagnetic lock dedicated and line cable are set on inside door, described temperature and humidity control device comprises temperature and humidity controller, Temperature Humidity Sensor, Displaying Meter and electric boiling plate, can ensure the inner unlikely condensation of cable hut and make moist.

The beneficial effect bringing is more than set is: cable hut is simple in structure, easy for installation, has taked multiple protection measure on electric insulation and mechanical protection simultaneously, has guaranteed that use safety and the working stability of 12kV cable hut is reliable.
