Problems solved by technology

However, after the cabinet door is opened, the operator's hand leaves the handle, the handle droops to restore the state of "locking the door", and the deadbolt rotates to the level. At this time, if the cabinet door receives an external force such as wind or manpower, it will hit If things go on like this, the lock tongue will be deformed, and when the door is locked again, the lock tongue will not easily rotate to the inside of the door frame to lock the door

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] A high security switchgear such as figure 1 , 2 As shown in and 3, a cabinet door 1 and a door frame 2 are included. A handle 11 is provided on the cabinet door 1. The upper end of the handle 11 penetrates into the cabinet door 1 and is provided with a rotating shaft 12. The end of the rotating shaft 12 located on the inside of the cabinet door 1 is set toward the door frame 2. Dead bolt 13 is arranged. When the cabinet door 1 is closed, the handle 11 is in a vertical state, and the dead bolt 13 is in a horizontal state, and the dead bolt 13 clamps the door frame 2, thereby locking the cabinet door 1 . When opening the cabinet door 1, the dead bolt 13 is rotated downward by turning the handle 11, so that the dead bolt 13 is detached from the interference with the door frame 2, and the cabinet door 1 is opened.

[0032] An elastic sheet 3 is arranged...

Abstract

The invention discloses a high-safety switch cabinet which comprises a cabinet door, a handle and a door frame. A spring bolt is connected onto the handle and is positioned on the inner side of the cabinet door, an elastic sheet is vertically arranged on the inner side of the cabinet door and is positioned below the spring bolt, a partition plate is arranged between the upper end of the elastic sheet and the cabinet door, a stop block is arranged on the side, which is far away from the cabinet door, of the elastic sheet and is provided with a slope surface which faces the door frame, and the door frame is provided with a pressure plate which faces the bottom of the elastic sheet. The high-safety switch cabinet has the advantages that the spring bolt can be prevented from deforming due to collision, and accordingly the cabinet door can be assuredly normally used.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high-safety switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformer...
