Description

Technical Field

[0001] This utility model relates to the field of plug-in box equipment, and more specifically, to a quick plug-in box for uninterrupted power switching. Background Technology

[0002] Busbar systems are a type of high-efficiency power distribution device widely used in the power distribution systems of high-rise buildings and large-scale factories to carry current.

[0003] Currently, a high-current live plug-in box is disclosed on the Chinese patent website, publication number CN210380165U, which includes a plug-in type plug-in box set at the upper end of a busbar trough; the top of the busbar trough is provided with a live connection box, and the left end of the plug-in type plug-in box is provided with a connection port that matches the live connection box; both sides of the top of the busbar trough are provided with L-shaped protrusions; the bottom of the plug-in type plug-in box is provided with several transverse sliding grooves, and each sliding groove is provided with a pulley group, each pulley group including a baffle and an L-shaped main frame; the bottom of the L-shaped main frame is connected to a pulley, and the outer wall of the pulley abuts against the side wall of the busbar trough; the baffle is connected to the opening of the sliding groove, and a locking screw is screwed onto the baffle by a thread, the end of the locking screw abuts against the side wall of one side of the L-shaped main frame, and a return spring abuts against the side wall of the other side of the L-shaped main frame. This device allows for easy connection of the plug-in box to the busbar trunking without power interruption, thus providing convenient access to the power supply inside the busbar trunking.

[0004] While the high-current live plug-in box in the aforementioned patent has the advantage of conveniently accessing the power inside the busbar trunking, it lacks a reserved detection point for detecting the line current. This means that when it is necessary to detect the line current, the plug-in box must be disassembled before the detection equipment can be electrically connected to the line for testing, which is a cumbersome, time-consuming, and labor-intensive process.

The mounting bracket includes two support beams that are arranged in parallel vertically and horizontally on the enclosure. The upper support beam is fixedly connected to the upper end of the back of the circuit breaker, and the lower support beam is fixedly connected to the lower end of the back of the circuit breaker.

[0015] The N-phase copper busbar of the three-phase busbar is connected to the upper support beam by insulating screws to fix its position. Similarly, the grounding copper busbar of the three-phase busbar is connected to the lower support beam by insulating screws to fix its position.

[0016] The upper support beam is connected to the upper part of the back of the circuit breaker by insulating bolts, and the lower support beam is connected to the lower part of the back of the circuit breaker by insulating bolts.

Open the insulating cover and connect the external testing mechanism to the busbar clamping bar by setting the busbar clamp.

[0023] During operation, an external testing agency will sample and test the mains current in real time. When the mains current is normal, the backup power supply does not work, and the mains power supplies the load. When the mains current is abnormal, the backup power supply starts to work and controls the circuit breaker to cut off the mains current, thereby ensuring that the load can work continuously without power.

[0024] This utility model has the following advantages: simple structure, convenient use, safe and efficient. Attached Figure Description
