Embodiment Construction
[0035] Such as Figure 1-7 As shown, the high-voltage isolating switch contact and the wire joint heating fault charging processing device are used to deal with the heating fault caused by the abnormal increase of contact resistance. The charging processing device includes evaluation components and spraying components; the evaluation components include A control module and an infrared temperature sensor wirelessly connected to the control module; the control module monitors the temperature of the heating fault position through the infrared temperature sensor, and evaluates it with a built-in evaluation basis. When the evaluation result is a fault state Send the spraying maintenance reminder to the staff, and the staff will use the spraying assembly to spray the conductive paste on the heating fault position under the charged state to reduce the contact resistance according to the prompt of the control module. When the temperature of the heating fault position is reduced and the...

The invention provides a high-voltage isolation switch contact and wire joint heating fault live-line processing device, which is used for processing a heating fault caused by abnormal increase of contact resistance, and is characterized in that the live-line processing device comprises an evaluation assembly and a guniting assembly; wherein the evaluation assembly comprises a control module and an infrared temperature measurement sensor connected with the control module in a wireless mode; the control module is used for monitoring the temperature of a heating fault position through the infrared temperature measurement sensor, evaluating the heating fault position according to a built-in evaluation basis, and sending a guniting maintenance prompt to a worker when the evaluation result is afault state. According to prompt of control module, a worker uses guniting assembly to spray conductive paste to heating fault position in electrified state to reduce contact resistance. When the temperature of the heating fault position is reduced and the evaluation result of the control module on the heating fault position is in a normal state, and the control module sends a fault removal prompt to a worker. According to the invention, equipotential live-line online processing of heating faults can be carried out without power failure.
Description
technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a device for processing live electricity for heating faults of high-voltage isolating switch contacts and wire joints. Background technique [0002] During the long-term electrified operation of the electric high-voltage equipment in the substation, due to current heating, surrounding environmental pollution, and rain erosion, etc., the fastening bolts of the high-voltage isolating switch contacts, high-voltage wire connectors, and clamps may be loosened, or the contact surfaces may be loosened. Oxidation, rust, etc., these will cause the contact resistance to increase continuously, resulting in heating defects higher than the normal heating temperature, if not resolved in time, the defects will continue to aggravate, resulting in a vicious circle, eventually leading to the joints being blown off and the high-voltage wires short-circuited And other malignant fai...
