高压防爆开关触头温度监测系统设计

Design on Contact Temperature Monitoring and Measuring System of High Voltage Flame Proof Switch

针对目前井下高压环境下温度监测较难的现状,设计了一种基于无线通信的高压防爆开关触头温度监测系统。该系统以nRF24L01为温度传感器的射频传输芯片,以ATMEGA88和CC2430为微控制器设计防爆开关内外的传输节点,给出了系统的硬件设计和软件流程。高压防爆开关触头温度监测系统在某额定电压10 kV、额定电流630 A高压开关柜实际运行显示表明,系统抗干扰能力强、温度监测准确、可靠,满足高压开关柜温度监测要求。

According to the present status of the difficult temperature monitoring and measuring in the underground mine high voltage environment,a contact temperature monitoring and measuring system of the high voltage flame proof switch was designed based on the wireless communication.Taking the nRF24L01 as the radio frequency transmission chip and taking the ATMEGA88 and CC2430 as the transmission nodes in and out of the flame proof switch designed for the micro-controller,the hardware design and the software process of the system was provided.The contact temperature monitoring and measuring system of the high voltage flame proof switch was applied to the high voltage switch cabinet with a rated voltage of 10 kV and a rated current of 630 A and the actual operation obviously showed that the anti interference capacity of the system was high and the temperature monitoring and measuring was accurate and reliable which could meet the temperature monitoring and measuring requirements of the high voltage switch cabinet.
