Description

Technical field: [0001] The invention relates to a wireless receiving device for low and zero-value resistance data of suspension insulators, which is widely used in live detection of low (zero) value resistance of suspension insulators in substations in electric power systems, and belongs to the field technical field of substation maintenance. Background technique: [0002] Suspension insulators in power systems are required to operate reliably under atmospheric overvoltage, internal overvoltage and long-term operating voltage. However, the simultaneous action of solid, liquid and gas particles deposited on the surface of the insulator and severe weather conditions such as fog, dew, drizzle, melting ice, and melting snow will greatly reduce the electrical strength of the insulator, so that the insulators of transmission lines and substations may be damaged. Flashover occurs under the action of overvoltage. More frequently, pollution flashover occurs under long-term operati...

Problems solved by technology

Due to the large noise in the substation, the sound of spark gap discharge is often covered up, which is easy to cause misjudgment. Therefore, it is urgent to develop a wireless receiving device for low (zero) value resistance data of suspension insulators.
