变电站开关柜良好的运行环境对设备的安全运行非常重要,目前开关柜采用的传统的除湿设备都有一定的局限性。本文设计了一种基于半导体技术的变电站开关柜的除湿设备,首先对该设备的除湿过程进行了数学建模,其次基于TI公司的TMS320C28X芯片搭建了硬件平台,采用PI控制进行温湿度的控制,最后通过模拟实际工作中的环境进行了实验,通过对实验值与理论值的比较,发现该设备可以快速达到除湿效果,证明该设备具有一定的稳定性和实用性。

The good operating environment of the switchgear is very important for the safe and stable operation of the power equipment.At present,the traditional dehumidification equipment used in switchgear has weakness.In this paper,a kind of dehumidification equipment for substation switchgear based on semiconductor technology is designed.Firstly,the dehumidification process of the equipment is modeled mathematically.Secondly,the hardware platform is built based on TMS320C28X chip of TI,and the temperature and humidity are controlled by PI control.Finally,the experiment is carried out by simulating the actual working environment.By comparing the experimental value with the theoretical value,it is found that the dehumidification effect of the equipment can be achieved quickly,which proves that the equipment has certain stability and practicability.
