Description

Technical Field

[0001] The utility model relates to the technical field of power supply control cabinets, in particular to a double-interlocking dual-power supply control cabinet. Background Art

[0002] The double-interlock dual power control cabinet is a dual power control device used to ensure safe and reliable switching of power systems. Through the dual interlocking mechanism of mechanical interlocking and electrical interlocking, it ensures that the normal power circuit breaker and the backup power circuit breaker will not be misoperated or short-circuited during the closing and switching process, thereby improving the safety and reliability of the system. This dual power control cabinet is suitable for places requiring high reliability and safety, such as hospitals, data centers, and industrial manufacturing.

[0003] When assembling an existing double-interlock dual-power control cabinet, the main power circuit breaker and the backup power circuit breaker are usually fixed directly to the cabinet body with bolts. However, the space inside the cabinet to accommodate the circuit breakers is small and closed, resulting in limited operating space, which is not conducive to the disassembly, installation, maintenance and inspection of the circuit breakers. Utility Model Content

[0004] The purpose of the utility model is to provide a double interlock dual power supply control cabinet which is convenient for circuit breaker inspection and maintenance, and effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] A double interlocking dual power control cabinet comprises a cabinet body, a common power circuit breaker and a backup power circuit breaker. Two mounting plate seats, both of which can slide back and forth, are installed in the inner cavity of the cabinet body. The common power circuit breaker is installed on one of the mounting plate seats, and the backup power circuit breaker is installed on the other mounting plate seat. A guide seat extending along the sliding direction of the mounting plate seat is fixed between the two mounting plate seats on the bottom wall of the inner cavity. A sliding hole extending along the length direction of the guide seat is provided in the guide seat. A sliding rod is slidably inserted in the sliding hole. One end of the sliding rod extends to the front side of the guide seat. Side grooves extending along the length direction and both sides of the guide seat are provided with side grooves extending along the length direction and passing through the sliding holes. Two connecting arms are symmetrically fixed to the outer surface of the sliding rod. The two connecting arms respectively pass through the side grooves on the corresponding sides and are fixedly connected to the mounting plate seats on the corresponding sides.

[0007] It can be seen that by pulling the sliding rod outward, under the connection action of the two connecting arms, the two mounting plate seats are driven to slide forward and extend to the outside of the cabinet, thereby driving the normal power circuit breaker and the backup power circuit breaker to move to the outside of the cabinet, exposing the normal power circuit breaker and the backup power circuit breaker, thereby facilitating the disassembly and maintenance of the normal power circuit breaker and the backup power circuit breaker. In addition, the connecting arm is installed through the side groove, on the one hand, it is used to connect the mounting plate seat and the sliding rod, on the other hand, the sliding cooperation between the side groove and the connecting arm plays a blocking and limiting role, which can prevent the sliding rod from sliding excessively and falling out of the sliding hole, killing two birds with one stone.

[0008] Furthermore, a pinching handle is fixedly mounted on the end portion of the slide rod located outside the guide seat, and an anti-slip pattern is provided on the outer peripheral wall of the pinching handle.

[0009] Furthermore, a socket is provided at the top of the guide seat near its front end, which is connected to the sliding hole, and a bayonet is inserted into the socket. A bayonet hole A is provided on the side of the slide rod near the pinching handle for the bayonet to be inserted into, and a bayonet hole B is provided on the side of the slide rod away from the pinching handle for the bayonet to be inserted into.

[0010] Furthermore, a sliding seat is fixed at the bottom of the two mounting plate seats, and a pair of guide rails are fixed on the bottom wall of the inner cavity. The two sliding seats are slidably installed on the corresponding guide rails. The guide rails are T-shaped rails, and the sliding seats are sliding seats with T-shaped sliding cavities.

[0011] Furthermore, mounting feet are evenly distributed on both sides of the common power circuit breaker and the standby power circuit breaker, each mounting foot is provided with a fastening bolt, and screw holes for fastening bolts to be screwed into are evenly distributed on the two mounting plate seats.

[0012] Furthermore, a cabinet door for sealing the inner cavity opening is hingedly mounted on the cabinet body, and a pair of yielding operation openings are provided on the cabinet door.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] The utility model pulls the sliding rod outward, and under the connection action of the two connecting arms, drives the two mounting plate seats to slide forward and extend to the outside of the cabinet, thereby driving the common power circuit breaker and the backup power circuit breaker to move to the outside of the cabinet, exposing the common power circuit breaker and the backup power circuit breaker, thereby facilitating the disassembly, assembly, maintenance and repair of the common power circuit breaker and the backup power circuit breaker.

[0015] The connecting arm in the utility model is installed through the side groove. On the one hand, it is used to connect the mounting plate seat and the sliding rod. On the other hand, the sliding cooperation between the side groove and the connecting arm plays a blocking and limiting role, which can prevent the sliding rod from sliding excessively and falling out of the sliding hole, thus killing two birds with one stone.

[0016] The utility model achieves a locking effect by aligning and inserting the bayonet pin into the bayonet hole A. When the common power circuit breaker and the standby power circuit breaker are disassembled, assembled, maintained, and repaired, the mounting plate base can be prevented from sliding randomly, thereby affecting the operation. By aligning and inserting the bayonet pin into the bayonet hole B, the positions of the two mounting plate bases can be locked to prevent sliding randomly, thereby ensuring the stability of the common power circuit breaker and the standby power circuit breaker during operation.
