Abstract

The invention relates to a three-post insulator temperature cycling test device and a test method. The three-post insulator temperature cycling test device comprises a three-post insulator tool, a temperature cycling device, a temperature sensor and a temperature control device, wherein the three-post insulator tool is used for fixing a to-be-tested three-post insulator; the temperature sensor is used for detecting the temperature of a central insert of the to-be-tested three-post insulator; and the temperature control device is respectively connected with the temperature sensor and the temperature cycling device, the temperature control device receives the temperature of the central insert, and according to the temperature of the central insert, the temperature cycling device is controlled to adjust the temperature of the central insert. By using the above device, temperature changes of the three-post insulator in actual GIL application can be simulated accurately, the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of insulator detection and testing, in particular to a three-pillar insulator temperature cycle testing device and method. Background technique [0002] As a transmission bus, gas-insulated high-voltage transmission line (GIL) is a kind of transmission equipment with broad development prospects, and has been widely used in large nuclear power plants and hydropower plants. The GIL structure is a metal pipe filled with an insulating gas, while a central conductor is used to transmit electrical energy. In practical applications, the central conductor needs to be supported and fixed by three-post insulators. It can be seen that the three-post insulator is a very critical device in the field of GIS. However, three-post insulators are susceptible to temperature effects in GIL applications, and their structure and electrical properties will change, resulting in changes in the force of the three-post insulator, so...
