Cabinet door structure of a central switch cabinet

Abstract

The invention discloses a cabinet door structure for a built-in switch cabinet, and the structure comprises a cabinet door, wherein one side end of the cabinet door is hinged to a cabinet from through a hinge, and the other side end of the cabinet door is connected with the cabinet from through a locking structure. The locking structure comprises a handle and a linkage column. The structure is characterized in that the locking structure also comprises a lock drive part, a lock connection part, a door lock part, and a locking hole; the central part of the lock drive part is vertically and fixedly connected with an end part, located at an inner side of the cabinet door, of the linkage column; one end of the lock connection part is hinged to any end part of the lock drive part in the length direction, and the other end of the lock connection part is a pull end; the whole door lock part is slidingly and cooperatively connected to a strip plate-shaped structure of an inner side surface of a side sealing plate of the cabinet door; the side surface, departing from the front surface of the cabinet door, of the door lock part is fixedly provided with a lock hook; the cabinet frame is provided with the locking hole corresponding to the lock hook. The above structure is higher in reliability.

Description

technical field [0001] The invention belongs to the field of electrical switch cabinets, and in particular relates to a cabinet door structure of a central switch cabinet. Background technique [0002] The power system is an electric energy production and consumption system including power generation (power plant), power transmission (transmission and transformation lines), power transformation (substation), power distribution (power distribution station or power distribution room) and power consumption. The switchgear is a kind of electrical equipment that switches, controls and protects the transmission line during the transmission and distribution process of the power system. Center-mounted switchgear (full name is metal armored center-mounted removable switchgear) is one of many types of switchgear, mainly used in the voltage level of 10kV to 35kV. A (handcart type) vacuum circuit breaker is installed inside the central switchgear. The vacuum circuit breaker can freque...

AI Technical Summary

Problems solved by technology

The above-mentioned locking structure is likely to be loose due to the deformation of the locking lever itself or the inaccurate guidance of the linkage track, resulting in loose meshing connection between the locking lever and the linkage gear, making the locking effect of the locking structure poor or lost.

It can be seen that the reliability of the above-mentioned locking structure still needs to be improved.
