Description

Technical Field

[0001] The invention relates to the technical field of plug-in boxes, and in particular to a plug-in box for a busbar. Background Art

[0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy. In the face of the huge loads of hundreds of amperes of strong current, it is necessary to use safe and reliable conduction equipment, and the bus duct system is a good choice. The bus duct system is a power distribution device that efficiently transmits current, especially adapted to the needs of economical and reasonable wiring of increasingly tall buildings and large-scale factories. As a functional unit of the power transmission bus duct, the plug-in box plays the role of distributing electrical energy in the bus duct system. With the development of power transmission and distribution, users have higher and higher requirements for the performance and operation of bus duct plug-in box products. There are many ways to install the plug-in box on the bus duct. After the plug-in box is plugged into the bus duct, it is very important to ensure that the plug-in box and the bus duct can be reliably connected and fixed. This will directly affect whether the plug-in box can operate reliably for a long time.

[0003] After searching, the patent document with application number 201710423514.1 discloses a plug-in box for a bus duct. By rotating the clamping handle, the lead screw is driven to rotate, thereby driving the second clamping block to move in the horizontal direction, so as to realize the rapid clamping or loosening of the bus duct plug-in box, ensure the reliable connection between the plug-in box and the bus duct, ensure the high-quality operation of the plug-in box and the bus duct, and further improve the installation efficiency; by rotating the switch handle, the connecting rod is driven to rotate, thereby driving the movable rod to move forward and backward, so as to realize the disconnection operation of the circuit breaker in the plug-in box body on the side of the plug-in box, and ensure safe operation.

[0004] The existing busbar plug-in box is inconvenient to store and seal when in use, and the plug-in box is exposed to the outside and easily affected by external factors, causing damage to the plug-in box. Therefore, we propose a plug-in box for a busbar to solve the above problem. Summary of the invention
