Abstract

The invention discloses a soil state monitoring device for fault early warning of a directly-buried GIL (Gas Insulated Line), which is used in the soil state monitoring device for fault early warning of the directly-buried GIL. The GIL shell comprises a high-voltage guide rod arranged at the central axis position of the GIL shell and a plurality of basin-type insulators connected between the high-voltage guide rod and the inner wall of the GIL shell; the multiple sets of temperature sensors and humidity sensors are arranged in soil on the lower side of the GIL shell and located under the basin-type insulators, and the data transmission module is connected with the multiple sets of temperature sensors and humidity sensors to collect temperature data and humidity data. And a computer terminal is connected with the data transmission module so as to identify the fault of the corresponding basin-type insulator based on the temperature data and the humidity data.

Description

technical field [0001] The invention relates to the technical field of electrical equipment insulation, in particular to a soil state monitoring device for direct-buried GIL fault early warning. Background technique [0002] Gas-Insulated Transmission Line (GIL) is a kind of high-voltage, high-current power transmission equipment that uses SF6 gas or a mixture of SF6 and N2 as insulation, and the shell and conductor are coaxially arranged. It has strong current-carrying capacity , low loss, high reliability and long service life. In addition, because direct-buried GIL can get along well with the landscape and can be laid continuously for thousands of meters or even tens of kilometers, it has been widely used in occasions where there are environmental restrictions and underground power transmission is required. [0003] In the process of GIL production, installation and operation, insulation hazards will inevitably occur, including metal particles, spikes, insulator air gaps...
