Abstract

The invention provides a method and a device for measuring salt density of contaminants on the insulator surface. The device includes a water spraying device and a detecting device. The water spraying device comprises a water storing box and a spray nozzle. The water storing box is connected with the spray nozzle through a guiding pipe. The detecting device comprises a probe and a detecting device body. The probe is used for transmitting electrical conductivity in pollution water to the detecting device body to measure the salt density. The method includes: (1) wetting the surface of the contaminant insulator, (2) detecting the electrical conductivity in pollution water of step 1 through the detecting device and (3) performing a conversion from the electrical conductivity to the salt density value. According to the method and the device, the salt density distribution of different positions of the insulator surface can be measured accurately, manpower and material resources are saved, the reliability of the salt density measuring is guaranteed and the measuring efficiency is increased. Further, the method and the device are convenient, effective and rapid.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a method and a device for measuring the pollution and salt density on the surface of an insulator. Background technique [0002] With the improvement of the operating voltage of the power system and the expansion of the power grid, more and more insulators are used for line insulation. Because line insulators are exposed to the air for a long time, it is easy to deposit dirt on its surface. The dirt contains electrolytic substances. Under humid weather conditions such as fog, dew, and drizzle, the electric strength of the insulator is greatly reduced, and the external insulation of the power system may be damaged. Under the action of overvoltage, a flashover occurs, causing a power outage and endangering the normal operation of the power system. [0003] The high-voltage insulator pollution test uses some test methods to obtain the pollution withstand voltage of ...
