Technical Field

[0001] The utility model belongs to the technical field of application of opening and closing switch locking of incoming line cabinet, in particular to an opening and closing switch locking device of incoming line cabinet. Background Art

[0002] With the rapid development of industrial modernization, the entire social system has put forward high requirements for the demand for electricity, especially for the continuous stability of power supply. For this reason, each power system will be equipped with a double power supply system to ensure that if a fault occurs during the power supply process, the power supply of the power equipment can be completely guaranteed. For this reason, the conventional design will set a double opening and closing device on the incoming line cabinet inside the power supply system, and adopt manual and automatic joint control. However, under the existing technology, during the process of incoming line maintenance operation, it is necessary to first determine the state of automatic opening and closing, and then perform maintenance or switching operations. However, in actual operations, generally more than two people enter the distribution room to operate. There are certain safety hazards in manual identification and operation, and there is a small probability of manual operation of repeated closing due to misoperation, which may cause unsafe accidents. For this reason, it is necessary to introduce a convenient locking device inside the incoming line cabinet, which does not require complicated confirmation actions. Utility Model Content
