　　變電所電纜無線測溫傳感器Circuit design and dual power management technology

　　The wireless temperature measurement and early warning system of high-voltage substation adopts dual-power management technology to manage the intelligent temperature sensor and the wireless transceiver module respectively, which can reduce the power consumption and improve the service life of the sensor. Due to the small working current of temperature sensor, ultra-low power single-chip microcomputer and peripheral circuit, 3.6V, 3000mA battery is mainly used for power supply in the circuit design process. The large continuous discharge current and large pulse discharge current of the battery can reach 150mA and 300mA respectively. Calculated according to 80 battery utilization rate, Life expectancy can reach more than two years. Through the control of single chip microcomputer to the current do not need to work on the parts of power protection, effectively improve the utilization rate of electricity. In addition, in order to effectively prolong the service life of the wireless temperature measurement early warning system in high-voltage substation, under the premise of meeting the operating frequency of equipment, a smaller working frequency can be selected to reduce the power consumption of the single-chip microcomputer. Moreover, energy consumption should also be emphasized in the design of peripheral circuits and equipment selection.

　　In the long-term operation process of high-voltage equipment, the temperature of many parts will rise sharply. For example, poor contact of switchgear contacts will lead to temperature rise and even burn, resulting in power outage accidents. Therefore, it is necessary to monitor the temperature of high voltage switchgear on line. The cT-BASED wireless temperature system does not need frequent battery replacement, which improves the reliability and practicability of the system. At the same time, this paper introduces how to realize the low power consumption of wireless temperature measurement system through software and hardware, and satisfy the use of small current of bus, and proves the practicability of this technology in practical application. Key words: CT power retrieval; High voltage equipment; Wireless temperature measurement; Low power consumption
