Problems solved by technology

When the user operates, he or she stands in front of the switch cabinet. When pushing or retreating, the contact of the contacts is blocked by the circuit breaker. The user cannot see it and cannot truly judge whether the fracture is disconnected. It does not meet the relevant standards and poses a safety hazard.
The branch busbars are distributed left and right, resulting in long copper busbars and high cost

Abstract

The invention discloses a built-in type switch cabinet. The built-in type switch cabinet comprises a cabinet body and a circuit breaker. The cabinet body is provided with a front cabinet plate; the cabinet body is internally provided with a three-phase static contact unit; the static contact unit comprises an upper static contact and a lower static contact; the upper static contact is electrically connected with a main busbar; the lower static contact is electrically connected with a branch busbar; the circuit breaker is provided with a three-phase moving contact unit; the moving contact unit comprises an upper moving contact and a lower moving contact; the three-phase static contact unit is arranged in tandem; the three-phase moving contact unit is arranged in tandem; the circuit breaker can be pushed into the cabinet body from the front of the cabinet and can move to the left and right between a test position and a work position; each phase of moving contact unit and each phase of static contact unit of the circuit breaker at the work position are contacted and electrically connected; and the front cabinet plate is provided with an observation window. The advantages are as follows: user operation is carried out in front of the cabinet, contact states can be observed through the observation window during operation, good isolation or contact is ensured, safety hidden risks are avoided, the performance is improved, the cost is reduced, and the reliability and safety are improved.

Description

technical field [0001] The invention relates to a central switch cabinet. Background technique [0002] The existing middle-mounted switch cabinet includes a cabinet body and a circuit breaker; the cabinet is equipped with a three-phase static contact unit, and each phase static contact unit includes an upper static contact and a lower static contact. The main busbar, the lower static contact is electrically connected to the branch busbar; the circuit breaker has a three-phase moving contact unit, each phase moving contact unit includes an upper moving contact and a lower moving contact, the upper moving contact and the lower moving contact The moving contacts are electrically connected; the three-phase static contact units are arranged left and right, and the three-phase moving contact units are arranged left and right. The circuit breaker can be pushed into the cabinet along the front and rear directions and move back and forth between the test position and the working pos...
