AI Technical Summary
In gas insulated metal sealed switch equipment (GIS), the dynamic and static contacts of the isolation and grounding switch are located in the metal shell, and the opening and closing state cannot be directly observed from the outside, which makes it difficult for operators to turn off the switch of the primary electrical equipment during the shutdown operation of the primary electrical equipment. Clarifying the position of the knife switch to be split and closed increases the chance of misjudgment, which may in turn cause grid and equipment accidents.
Provide a GIS switch endoscopic visual monitoring equipment, including main equipment and light supply equipment. By setting an observation joint on the side wall of the equipment cavity and opening a camera through hole in the observation joint, the camera is used to monitor the movement process of the switch contact. , to achieve visual monitoring of the opening and closing status.
Through endoscopic visual monitoring equipment, it can effectively assist in determining whether the switch opening and closing is in place, quickly locate the internal fault point of the GIS, reduce the risk of misjudgment, and improve the safety of the power grid and equipment.

Abstract
Description
Technical Field
[0001] The present application relates to the field of gas-insulated metal-enclosed switchgear, and in particular to an endoscopic visualization monitoring device for a GIS switch. Background Art
[0002] Gas insulated metal enclosed switchgear (GIS) is a metal enclosed switchgear and controlgear that uses gas above atmospheric pressure as the insulating medium in at least one part. It is filled with SF6 insulating gas at a certain pressure, and is also called SF6 fully enclosed combination electrical equipment. Gas insulated metal enclosed switchgear (GIS) is one of the most important equipment in the high-voltage electrical equipment of the power grid. It is used for the power transmission and transformation system to separate and separate no-load, load and fault current, convert loads, isolate lines, ground protection and measure electricity, etc. It plays an extremely important role in the power system. GIS is a closed device. When a fault occurs, the power outage time is long and the impact range is large. The moving and static contacts of the isolation and grounding switches are located in the metal shell, and their opening and closing states cannot be directly observed from the outside. During the switching operation of the electrical primary equipment by the operating personnel, the opening and closing positions of the knife switches must be clearly judged. If the position of the knife switch is difficult to observe and identify, the probability of misjudgment will increase. Misjudgment is very likely to cause power grid and equipment accidents, and there are major safety hazards. Summary of the invention
[0003] The purpose of the embodiment of the present application is to provide an endoscopic visualization monitoring device for a GIS switch, which can observe and record the movement process of the switch contacts. On the one hand, it can serve as an auxiliary means of judging whether the opening and closing are in place. On the other hand, it can quickly locate the fault point when an internal fault occurs in the GIS.
