Abstract

The invention provides a device and method for evaluating the insulation state of a composite cross-arm insulator, and the device comprises a monitoring device which is disposed on the composite cross-arm insulator, and is used for obtaining a signal of the surface leakage current of the composite cross-arm insulator; the transmission device is electrically connected with the monitoring device andused for receiving and transmitting signals. And the analysis device is electrically connected with the transmission device and is used for receiving the signal, analyzing and processing the signal and determining an evaluation result. In the present invention, the monitoring device acquires a signal of surface leakage current of the composite cross arm insulator in real time. The analysis deviceanalyzes and processes the signal and determines an evaluation result of the insulation state of the composite cross arm insulator; the insulation state of the composite cross-arm insulator can be monitored in real time, the electrical insulation performance of the surface of the composite cross-arm insulator can be accurately monitored, the operation state of the composite cross-arm insulator can be accurately evaluated and early warned, an evaluation result can be obtained through intelligent analysis, manual participation is not needed, and the method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of electrical equipment performance monitoring, in particular to an evaluation device and evaluation method for the insulation state of a composite cross-arm insulator. Background technique [0002] The tower frame is one of the most important components of the overhead transmission line. Generally speaking, steel occupies most of the market for the transmission tower frame due to its advantages such as high strength, stable performance, and easy connection. However, with the development of power grid construction, the demand for steel is also increasing, consuming a large amount of materials and materials, and causing serious pollution to the ecological environment. Compared with conventional steel towers, composite insulation towers have the advantages of anti-fouling, good lightning protection, light weight, and convenient installation. Applying them to power transmission lines can generate good economic ...
