The invention provides an electrical equipment detection device based on an acoustic surface wave, and relates to the electrical equipment detection device. The invention solves a problem that remoteelectrical equipment is difficult for measurement in the prior art. The electrical equipment detection device comprises an acoustic surface wave temperature sensor, and a fixing device for fixing theacoustic surface wave sensor. The acoustic surface wave temperature sensor comprises a chip, a thermal conduction ceramic circuit board, and a spiral antenna. The chip is disposed on the thermal conduction ceramic circuit board, and the spiral antenna is fixed on the thermal conduction ceramic circuit board, and is connected with an antenna connection terminal on the chip. The fixing device comprises a substrate and a housing, and the acoustic surface wave temperature sensor is disposed on the substrate. The substrate is provided with the housing, and the acoustic surface wave temperature sensor is sealed in the housing. The device is small in size, is light in weight, does not need an external power supply, works in a wireless mode, has the waterproof and insulating characteristics, and is suitable for the temperature measurement of an outdoor high-voltage environment.
