Anti-intrusion live compartment high-voltage switchgear

Abstract

A high-voltage switchgear for anti-mis-entry live intervals belongs to the technical field of high-voltage switchgears, and in particular relates to a high-voltage switchgear for anti-mis-entry live intervals. The invention provides a high-voltage switchgear with safe use and anti-mis-entry into charged intervals. The invention comprises a switch cabinet body, on which a grounding knife operation hole is arranged, and a grounding knife operation shaft is arranged in the grounding knife operation hole, a cam is arranged on the grounding knife operation shaft, and the upper end of the cam is provided with a first limit position groove and the second limit groove, the inner wall of the switch cabinet is provided with a vertical cam locking mechanism corresponding to the first limit groove and the second limit groove; the lower side of the cam is provided with an arc opening, and inside the arc opening is Horizontal connecting rod, the outer end of the horizontal connecting rod is connected to the upper end of the vertical connecting rod, the lower end of the vertical connecting rod is axially connected to the vertical baffle, one end of the vertical baffle is axially connected to the inner wall of the switch cabinet through the connecting rod, and the connecting rod is connected to the upper end of the spring shaft connection.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and in particular relates to a high-voltage switchgear for preventing misentry into a charged compartment. Background technique [0002] The 10KV interval switch in the existing 66KV substation uses a high-voltage switchgear with five prevention measures, but there are many operations in the operation of the substation. After the operation and maintenance personnel of the substation complete the operation on the front of the switchgear, there is In many cases, it is necessary to go to the back of the switch cabinet and open the door of the rear partition to carry out operations. When transferring the working position, due to the lack of obvious instructions in the rear partition and the negligence of the staff, coupled with the loss of supervision, it is easy to make mistakes or enter the charged partition by mistake. cause casualties.
