Description

Technical Field

[0001] The utility model relates to the technical field of excitation power cabinets, in particular to a cabinet door mechanism and an excitation power cabinet. Background Art

[0002] The excitation cabinet is an important part of the synchronous motor. The DC excitation of the synchronous generator rotor winding is a necessary condition for converting mechanical energy into electrical energy. The source that supplies DC power to the excitation winding of the synchronous motor is generally called the excitation cabinet (or exciter). The excitation cabinet plays an extremely important role in the operation of the generator set and even the entire power grid. The excitation cabinet and control play a significant role in maintaining the terminal voltage of the generator, the reactive power distribution between the generator sets, the static and transient stability limits, and suppressing various oscillation phenomena, and improving the dynamic quality of the power system.

[0003] Most of the existing excitation power cabinets are multiple power cabinets placed side by side. When the cabinet door is opened, it is easy for the cabinet door to collide with the cabinet body. The shaking caused by this collision may cause the connection between the circuit on one side of the cabinet door and the display and control button to loosen, thereby affecting the contact quality between the control button and the connector, making the control button unable to operate normally. In addition, the existing cabinet door lacks an effective prompt function during use, and it is difficult for users to quickly determine whether the cabinet door has been locked. At the same time, during the operation of the existing cabinet body, a large amount of dust often accumulates at the heat dissipation port. If it is not removed, it will affect the heat dissipation efficiency of the cabinet body. Utility Model Content
