Abstract

The invention relates to a transformer substation equipment monitoring device based on a passive wireless sensing technology, and the device comprises: a plurality of surface acoustic wave sensors, wherein each surface acoustic wave sensor comprises a piezoelectric substrate, a difference type transducer and a reflector, the difference type transducer and the reflector are both disposed on the piezoelectric substrate, and the difference type transducer is connected with the reflector, the difference type transducer is used for receiving a wireless excitation signal and converting sound energyof the wireless excitation signal into an electric signal, and the piezoelectric substrate is used for generating an echo reflecting information of an external environment when receiving the electricsignal and sending the echo to the reflector, so that the light beam is reflected by the reflector; and a temperature measurement main control terminal which is used for receiving the echoes emitted by the plurality of surface acoustic wave sensors and obtaining temperature, pressure and vibration changes outside the measured object according to the echoes. The monitoring equipment is high in accuracy and wide in application range.

Description

technical field [0001] The invention relates to the technical field of substation equipment monitoring, in particular to a substation equipment monitoring device based on passive wireless sensing technology. Background technique [0002] The primary electrical equipment of the power system is generally composed of circuit breakers, transformers, cables, busbars, switch cabinets and other electrical equipment. They are connected with each other by busbars, leads, cables, etc. Since the current flows to generate heat, almost all electrical faults will lead to changes in the temperature of the fault point. For example, overheating of cable joints, cable intermediate connections, partial discharge of high-voltage cables, moving and static contacts of high-voltage switchgear and other connections, low-voltage electrical connections in substations is a sign of large-scale accidents, and it is also a hard-hit area where accidents frequently occur in power plants. . [0003] The i...
