Temperature monitoring system and method for high-voltage charged body with zero power consumption chip implantation and wireless network mode

Abstract

The invention discloses a temperature monitoring system and method for a high-voltage charged body with a zero power consumption chip implantation and wireless network mode. The temperature monitoring system comprises a computer, a database, a zero power consumption chip sensor and a radio transceiver, wherein temperature-sensing elements of piezoelectric materials are integrated inside the zero power consumption chip sensor; the zero power consumption chip sensor, a thin-type chip, is integrated with an interdigital transducer and a semiconductor having a "seebeck effect" , and is pasted onto the surface of the high-voltage charged body with a heat transfer coating material as a medium. With a temperature sensing mode which is characterized in that the zero power consumption chip is directly implanted into the high-voltage charged body, the theoretical power consumption of the chip is zero, and thus defects of current sensing modes in the prior art are compensated; besides, with the adoption of a wireless network transmission mode, a full isolation is really realized. With the technical scheme, problems of insulation and power supply in temperature measuring of the high-voltage charged body are completely solved, and the high-voltage charged body can be monitored online in real time.

Description

technical field [0001] The invention relates to the technical field of smart grid state monitoring, in particular to a wireless network temperature monitoring system and method for a high-voltage electrified body with zero power consumption chip implantation. Background technique [0002] During the long-term operation of important high-voltage live equipment such as high-voltage switchgear, busbar joints, and outdoor knife switches in power plants and substations, the connection points between switch contacts and busbars will heat up due to aging or excessive contact resistance, forming a vicious circle: Heating, expansion, contraction, oxidation, resistance increase, and heating again will cause equipment overheating and even serious accidents. Therefore, closely monitoring the temperature of electric high-voltage live equipment is an essential means to ensure the reliable operation of electric power equipment. [0003] In the prior art, the temperature monitoring methods...
