Intelligent bus duct and jack box

Abstract

The invention discloses an intelligent bus duct and a jack box. The bus duct comprises a bus duct body and a plug-in connector, wherein the bus duct body comprises a metal shell and a plurality of copper bars arranged in the metal shell side by side; insulation protection layers are arranged on the surfaces of the copper bars, a mineral substance fireproof layer wrapping all the insulation protection layers is further arranged in the metal shell, and the space between the mineral substance fireproof layer and the inner side wall of the metal shell is filled with a ceramic silicone rubber waterproof and moistureproof layer. The plug-in connector comprises a rectangular metal pipe body with openings at two ends, the metal pipe body comprises a middle pipe body and end pipe bodies symmetrically arranged on the outer sides of the two ends of the middle pipe body in a sliding mode. The inner side wall of the other end of the end pipe body is connected with the outer side wall of one end ofthe metal shell in a sliding mode, a plurality of conductive copper plates used for being correspondingly connected with copper bars on the two sides are arranged in the middle of the inner side of the middle pipe body, and a plurality of temperature sensing optical fibers and signal modulators which are correspondingly connected with the copper bars respectively are arranged on an insulating plate.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an intelligent busway and a plug-in box. Background technique [0002] The fire-resistant busway is composed of a shell coated with fire-resistant paint, a busbar wrapped with fire-resistant mica tape and a bracket made of fire-resistant insulating material. There are multiple grooves on the bracket, and the grooves are built into the busbar and fixed. There is a bus duct connection box at one end of the bus duct, and a bus junction box inside the bus duct. Modern high-rise buildings and large workshops require huge electric energy, and in the face of the huge loads that require hundreds of thousands of amperes of strong current, safe and reliable conduction equipment must be selected. The busway was developed by the United States and is really practical in Japan. After application, the busway has been developed rapidly. The busway is a power distribution device for h...

Problems solved by technology

[0003] When the copper bar of the busway is connected to the plug-in box, the connection is prone to abnormal heating, which poses a safety hazard. Therefore, its temperature needs to be monitored, and the existing monitoring method requires an additional network for signal transmission. ,higher cost

[0004] In addition, the internal structure of the existing refractory busway only installs a layer of mica tape on the surface of the copper bar, then assembles it with steel plates, and finally sprays a layer of fire-resistant paint on the surface of the steel plate. The refractory material has poor fire-resistant effect. And the internal current increases, the fire-resistant bus duct will deform and fail, and its normal and stable power transmission in the event of a fire cannot be guaranteed. Therefore, the existing fire-resistant bus duct can only maintain normal power transmission for a short time in the event of a fire
