Description

technical field [0001] The invention relates to an on-line temperature monitoring device for high-voltage power equipment, in particular to a photoelectric conversion collar structure for on-line high-voltage temperature monitoring. Background technique [0002] The poor electrical contact state of the conductive connection and socket of the power equipment is an important reason for the overheating of the place, even under normal current, the maximum allowable temperature will be exceeded. The parts of the switchgear that often fail are the contacts and the cable connections of the incoming and outgoing wires. Most of these devices are closed structures, and the doors or covers that block infrared radiation cannot be opened during operation for infrared detection; some outdoor devices are inconvenient to detect, and the detected temperature is not accurate and cannot be monitored online. [0003] For the current on-line monitoring of the temperature of the removable switch...
