Abstract

The invention discloses a self-energizing wireless temperature sensor using electromagnetism, comprising a casing, and a PCB board installed in the casing, wherein two communicating slots are formed on both sides of the casing; the PCB board is provided with an energy collecting unit, a rectifying circuit, a voltage stabilizing protection module and a main control IC chip; the main control IC chipcontains a micro control unit and an RF radio frequency processing unit; the energy collecting unit comprises a coil bobbin, which is fixedly mounted on the PCB board; and alloy strips are provided in the communicating slots and in the hollow of the coil bobbin. The self-energizing wireless temperature sensor using electromagnetism has ultra-low power consumption, micro-electromagnetic energy collection, no need of battery, and radio frequency communication, has the advantages such as green environmental protection, maintenance-free, thorough electrical isolation, convenient installation, strong anti-interference ability, reliable work and small size, and can well solve the temperature measurement problem under high voltage state. By transmitting the collected temperature to the monitoring terminal through radio frequency communication in real time, intermittent data transmission and accurate measurement are realized.

Description

technical field [0001] The invention relates to the technical field of high-voltage temperature monitoring equipment, in particular to a wireless temperature sensor using electromagnetic self-power. Background technique [0002] In recent years, with the continuous growth of the economy, the demand for electricity is increasing, making the power system develop in the direction of large capacity, high voltage and intelligence, and the safe and efficient operation of the power system is closely related to the healthy development of the social economy and the people. stability of life. [0003] In various electrical equipment such as contacts and contacts of high and low voltage switchgear, knife switch, intermediate head of high voltage cable, dry type transformer, low voltage and high current cabinet, etc., the temperature rise caused by factors such as material aging, poor contact and current overload High, and unsuitable for detection of potential failures, the electrical ...
