Intelligent video monitoring system for isolating switch state in high-voltage switch cabinet

Abstract

The invention belongs to the field of high-voltage power transformation (distribution) engineering, and particularly relates to an intelligent video monitoring system for switch-off / switch-on state of an isolating switch and / or a grounding switch in a full-metal sealed type high-voltage switch cabinet. The intelligent video monitoring system has the structure that a camera is arranged in the switch cabinet and is connected with an intelligent video coder; the intelligent video coder is connected with a switchboard through an internet access; the switchboard is linked with a local area network, and the local area network is linked with a video analysis control center; and a lighting device is arranged on the camera. According to the intelligent video monitoring system for the isolating switch state in the high-voltage switch cabinet, the camera arranged close to contacts of the isolating switch and the grounding switch is used for acquiring the image data of the isolating switch and the grounding switch; and the acquired images can be subjected to multidirectional contrast analysis through the video analysis control center, thus the analysis result is accurate, the circumstance of error determination can be prevented, and the switch off / switch on states of the switches in the switch cabinet can be remotely monitored.

Description

technical field [0001] The invention relates to a switch cabinet opening and closing state monitoring device, in particular to an intelligent system for monitoring the states of an isolating switch and a grounding switch in an all-metal-enclosed high-voltage switch cabinet through images of the switch opening and closing states. Background technique [0002] The existing high-voltage switchgear is equipped with isolating switches and / or grounding switches. Since the high-voltage switchgear is a fully enclosed metal cabinet, the opening and closing status of the above switches are generally known through the following methods: First, set a transparent switch on the switchgear. The opening and closing state of the switch in the cabinet can be observed with the naked eye; the second is to mark the opening, closing and interlocking positions corresponding to the pointer on the cabinet surface through the rotation position of the pointer on the handle connected to the switch movab...

The disadvantages of the above two methods are that they are all on-site observation by personnel; second, it is easy to cause misjudgment. For example, in the case of multiple switches in the cabinet in the first way, it is easy to misjudgment; Circumstances that lead to miscarriage of justice
