Problems solved by technology

[0002] The switchgear is a common power transmission and distribution equipment, which plays a role of control or protection in the process of power transmission and distribution; in the process of manufacturing, distribution, installation, operation and maintenance of the switchgear, it will inevitably cause various problems in the switchgear If the internal state of the switchgear is not detected early and allowed to develop to a serious degree, it will eventually lead to insulation damage in the switchgear and cause safety accidents, which will bring huge economic losses and negative social impacts to power generation enterprises
[0003] It is forbidden to open the cabinet door to observe the internal state during normal operation of the switchgear, so it is impossible to obtain the internal state of the switchgear intuitively; at present, built-in sensors are commonly used to monitor internal faults. Since one sensor can only monitor one point of failure, too many sensor arrangements will It affects the internal insulation state of the switch cabinet, and too few sensors cannot obtain complete information inside the switch cabinet; therefore, it is necessary to monitor the internal state of the switch cabinet without opening the cabinet door and installing equipment in the switch cabinet. When the original insulation state of the switchgear remains unchanged, the monitoring of the internal state of the switchgear can be realized, and hidden faults inside the switchgear can be found in time
