Abstract

The invention relates to the substation equipment contact temperature monitoring technologies, in particular to a bus network platform for online monitoring of substation equipment contact statuses, and solves the problems that the existing substation equipment contact temperature monitoring platform is unstable in transmitting, poor in transmission reliability, poor in interference resistance, difficult to wire, poor in measurement accuracy, poor in measurement safety, high in maintenance cost and low in measurement precision. The bus network platform for online monitoring of the substation equipment contact statuses comprises two acquisition layers, a transmission layer and a monitoring layer; each acquisition layer comprises m SAW (surface acoustic wave) temperature sensors, m small normal helical antennas, a helical-arm dipole antenna, a wireless temperature acquirer and a wireless universal serial bus; the m small normal helical antennas, the helical-arm dipole antenna and the wireless universal serial bus jointly form a bus topological structure. The bus network platform for online monitoring of the substation equipment contact statuses is applicable to substations.

Description

technical field [0001] The invention relates to a temperature monitoring technology for substation equipment contacts, in particular to a bus-type network platform for on-line monitoring of substation equipment contact states. Background technique [0002] During the long-term operation of substation equipment, its contacts (mainly the dynamic and static contacts and cable joints in the switch cabinet) are prone to long-term heating and high temperature rise due to aging or excessive contact resistance, which may cause equipment Faults (mainly switchgear burning faults and short-circuit blasting faults), which seriously threaten the safe operation of the power grid. Therefore, in order to prevent the occurrence of the above faults, the temperature monitoring platform of substation equipment contacts (mainly the dynamic and static contacts and cable joints in the switch cabinet) is mainly used to monitor the temperature of substation equipment contacts. Under the existing te...
