Abstract

The invention discloses an experimental device for temperature measurement of GIS disconnector shell fiber grating temperature sensors, which comprises a large current generator, a temperature measurement system, a GIS disconnector and a plurality of shell temperature sensors. The GIS disconnector comprises a contact, and the shell temperature sensors are fixed on the contact. Every two shell temperature sensors are fixedly arranged at an interval of 45 degrees. The contact of the GIS disconnector is also connected with the large current generator. The temperature measurement system is connected with the GIS disconnector. According to the invention, the layout of the GIS disconnector shell temperature sensors is optimized, the temperature of the contact is inverted by using a support vector machine, and an optimal sensor layout scheme is determined by combining the advantages, so as to improve the accuracy of temperature monitoring of the disconnector contact based on a GIS shell and environmental temperature measurement.

Description

technical field

[0001] The invention relates to the technical field of GIS equipment, in particular to a temperature measurement experimental device of a grating optical fiber temperature sensor for a shell of a GIS isolating switch. Background technique

[0002] Gas Insulated Switchgear (GIS) is not affected by the environment, short construction and installation time, low construction cost, safe and reliable operation, less maintenance workload, low operating cost, free from radio interference, small footprint, etc. Advantages Rapid development and widely used in high voltage and extra / ultra high voltage fields of power systems, and will be applied on a larger scale in the future. GIS equipment is a fully enclosed switchgear with high operational reliability, but due to its compact structure and tight packaging, the problem of overheating of equipment contacts is particularly serious, and failure will cause serious economic losses. Therefore, after GIS equipment is put int...
