Substation equipment contact state on-line monitoring mesh network platform

Abstract

The invention relates to the substation equipment contact temperature monitoring technology, in particular to a substation equipment contact state on-line monitoring mesh network platform. The problems that an existing substation equipment contact temperature monitoring platform is instable in transmission, poor in transmission reliability, poor in antijamming capability, high in wiring difficulty, poor in measurement accuracy and measurement safety, high in maintenance cost and low in measurement precision are solved. The substation equipment contact state on-line monitoring mesh network platform comprises two collection layers, a transmission layer and a monitoring layer. Each collection layer comprises m SAW temperature sensors, m normal small spiral antennas, a spiral arm dipole antenna and a wireless temperature collector, wherein the m SAW temperature sensors are connected with the m normal small spiral antennas in a one-to-one corresponding mode, and the m normal small spiral antennas and the spiral arm dipole antenna are connected in a two-to-two mode to form a mesh topological structure. The substation equipment contact state on-line monitoring mesh network platform is applicable to substations.

Description

technical field [0001] The invention relates to a temperature monitoring technology for substation equipment contacts, in particular to a mesh network platform for online 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 technic...
