Problems solved by technology
At present, the plug-in box shell and the busway shell are generally connected by clamping parts and bolts. It is difficult to ensure the quality of product operation whether the plug-in box and the busway are firmly fixed; the structural operation of the traditional plug-in box The internal circuit breaker can only be disconnected through the operating mechanism on the door of the plug-in box. When the installation and operation space is insufficient or the user has special operating requirements, the above-mentioned traditional structure will be helpless

The invention relates to a plugging connection box for a bus duct. A screw is driven by the rotation of a clamping handle to rotate, thereby driving a second clamping block to move in the horizontal direction, achieving the quick clamping or loosening of the plugging connection box for the bus duct, guaranteeing the reliable connection between the plugging connection box and the bus duct, guaranteeing the high-quality operation of the plugging connection box and the bus duct, and further improving the installation efficiency. A switch handle rotates to drive a connecting rod to rotate, thereby driving a movable rod to move back and forth, achieving the breaking operation of a circuit breaker in the body of the plugging connection box on a side surface of the plugging connection box, and guaranteeing the safe operation.
Description
technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a plug-in box for a busway. Background technique [0002] Modern high-rise buildings and large workshops require huge amounts of electric energy, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, safe and reliable conduction equipment must be selected, and the busway system is a good choice. The busway system is a power distribution device for efficient current transmission, especially to meet the needs of economical and reasonable wiring of increasingly taller buildings and large-scale factories. As a functional unit of the power transmission busway, the plug-in box plays the role of distributing electric energy in the busway system. With the development of power transmission and distribution, users have more and more requirements on the performance and operation mode of the busway plug-in box products. high. T...
