Abstract

The invention discloses a multi-sensor partial discharge sound signal phase detection circuit. The power output end of a power module is electrically connected with the power end of a control module, the power end of a first sound reproduction module, the power end of a second sound reproduction module, the power end of a third sound reproduction module, the power end of a fourth sound reproduction module, the power end of a fifth sound reproduction module and the power end of a sixth sound reproduction module. The signal transmission end of the first sound reproduction module, the signal transmission end of the second sound reproduction module, the signal transmission end of the third sound reproduction module, the signal transmission end of the fourth sound reproduction module, the signal transmission end of the fifth sound reproduction module and the signal transmission end of the sixth sound reproduction module are electrically connected with the signal transmission end of the control module, and the power supply module comprises +5V and +15V. The first sound reproduction module, the second sound reproduction module, the third sound reproduction module, the fourth sound reproduction module, the fifth sound reproduction module and the sixth sound reproduction module are sequentially distributed in a spherical shape. The detection circuit has the advantages of strong anti-interference performance, accurate measurement and the like.

Description

technical field [0001] The invention relates to the technical field of detection circuits, and more specifically, to a multi-sensor partial discharge sound signal phase detection circuit. Background technique [0002] Electrical equipment is the basic component of the power system and the basis for ensuring the reliability of power supply. Statistical data at home and abroad show that the deterioration of electrical equipment insulation performance is the main cause of its failure, which may lead to large-scale power outages in severe cases. Partial discharge is not only a symptom of insulation deterioration of electrical equipment, but also a key factor causing insulation deterioration. Switchgear is a kind of electrical equipment, its main function is to open and close, control and protect the running power generation, transmission, distribution and power conversion equipment. The normal operation of the switchgear is an important guarantee for the safe, reliable and eco...
