The invention relates to the substation equipment contact temperature monitoring technology, in particular to a substation equipment contact state on-line monitoring star 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 star 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 form a star topological structure together. The substation equipment contact state on-line monitoring star network platform is applicable to substations.
Description
Technical field [0001] The invention relates to a temperature monitoring technology for the contact points of substation equipment, in particular to a star network platform for on-line monitoring of the contact status of substation equipment. 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 excessive temperature rise due to aging or excessive contact resistance, which causes the equipment Faults (mainly the switchgear burning fault and short-circuit firing fault), which seriously threaten the safe operation of the power grid. Therefore, in order to prevent the occurrence of the above-mentioned faults, the temperature monitoring platform of the substation equipment contacts is currently mainly used to monitor the temperature of the substation equipment contacts (mainly the dynamic and static contacts and cable joints i...
