Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of excitation cabinets, in particular to a new excitation cabinet that prevents mis-opening. Background Art
[0002] Excitation is a machine that provides stator power to the synchronous motor stator and provides a working magnetic field for the motor (electrical equipment that works on the principle of electromagnetic induction). The excitation cabinet is a cabinet that holds the excitation.
[0003] Since the excitation cabinet is related to the power distribution in the electrical equipment, the door lock of the excitation cabinet should be kept by a dedicated person. Therefore, the excitation cabinet can usually only be opened for maintenance when there is a circuit failure, and it cannot be opened easily. If the cabinet door can be opened freely, it is easy to cause accidents and a series of economic losses. For personal behavior with the intention of opening the door deliberately, even a locked excitation cabinet cannot prevent the deliberate unlocking behavior, but it cannot be completely left alone. However, if there is no lock, the cabinet door of the excitation cabinet is extremely easy to be opened.
[0004] Based on this, this scheme proposes a new excitation cabinet that prevents accidental opening. Utility Model Content

[0012] Preferably, universal wheels are rotatably mounted on the four corners of the bottom of the cabinet.
[0013] By adopting the above technical solution, the movement of the entire device is facilitated by the universal wheels.
[0014] Preferably, a handle is fixedly mounted on the outer side of the cabinet door.
[0015] By adopting the technical solution, the cabinet door can be easily pulled by the handle.

Since the crank is set on the back of the cabinet, it is difficult to be found; when the cabinet door needs to be closed, the cabinet door is closed first, and then the above operation is repeated in reverse. The utility model has a simple structure and is easy to use. The new excitation cabinet that prevents accidental opening has an additional limit component on the basis of the original door lock. When the cabinet door is closed, double limit can be performed, and non-staff cannot open the cabinet door only by using a key, thereby preventing the excitation cabinet from being opened by mistake and protecting the excitation cabinet.
