Abstract

The invention relates to a switch cabinet. The switch cabinet comprises a cabinet body with a handcart chamber. The front side of the cabinet body is provided with a handcart door panel, and the cabinet body is internally provided with a movable door corresponding to the handcart chamber at the rear side of the handcart chamber. The cabinet body is internally provided with a movable door driving and connecting rod for driving the movable door to open or close. A horizontal interlocking member in transmission connection with the movable door driving and connecting rod is slidably assembled in the cabinet body along a left-right direction. A vertical interlocking member is movably assembled in the cabinet body in the vertical direction at the front side of the horizontal interlocking member.The vertical interlocking member is connected with a reset elastic member which applies a force to the vertical interlocking member so as to force the vertical interlocking member to reset. The handcart door panel is provided with an ejection pressing part which overcomes an acting force of the reset elastic member to drive the vertical interlocking member to move. The interlocking and anti-interlocking of the handcart door panel and the movable door are realized, so that the handcart can only drive the movable door driving and connecting rod to act when the handcart door panel is closed, andthe handcart door panel cannot be opened when the handcart is in a non-test position, thereby guaranteeing the safety of the operator.

Description

technical field [0001] The invention relates to a switch cabinet. Background technique [0002] AC high-voltage cabinet (KYN61) is an AC metal-enclosed switchgear that controls, protects and detects circuits, and is widely used in power plants, substations and working enterprises. The valve in the switch cabinet and the contact box form a closed chamber, which isolates the high-voltage live contacts and ensures the safety of maintenance personnel. The valve mechanism is mainly used for opening and closing the valve to ensure that the valve can be opened in time when the circuit breaker is moved in, and the valve can be closed in time when the circuit breaker is shaken out. [0003] The Chinese utility model patent with the authorized announcement number CN204858379U and the authorized announcement date of 2015.12.09 discloses a high-voltage switchgear with a valve interlock mechanism, including a cabinet body and a connecting rod valve mechanism. The connecting rod valve me...
