冬季水冲洗车排水防寒措施试验研究
Experimental Study on Winter Water Washing Vehicle Drainage and Cold Prevention Measures

为了解决接触网绝缘子水冲洗车排水时间长，冬季排水困难，且排水过程中容易结冻的问题，文章提出采用电伴热保温措施和一种高压气流辅助快速排水的方案，在水冲洗车作业完毕后，通过“一键排水”的自动化控制方式，打开系统排水阀门，利用高压风机约260 mbar的压力对整个水冲洗系统管道内进行加压，实现快速排水。经过设计试验方案验证：通常自然排水时间长达30分钟左右；而经过高压气流辅助排水，排水时间只需要5分钟时间。试验证明水冲洗系统排水时引入高压气流可使排水效率大幅提高，且高压风机产生的热风高达64℃，更有利于冬季排水时防止结冻现象产生。
In order to solve the problems of long drainage time, difficult drainage in winter, and easy freezing during the drainage process of the contact network insulator water flushing vehicle, it is proposed to adopt electric heat tracing insulation measures and a high-pressure airflow assisted rapid drainage scheme. After the water flushing vehicle operation is completed, the system drainage valve is opened through the automatic control method of “one click drainage”, and the entire water flushing system pipeline is pressurized using a high-pressure fan with a pressure of about 260 mbar to achieve rapid drainage. After verification of the design test plan, it was found that the natural drainage time is usually up to about 30 minutes. After high-pressure airflow assisted drainage, the drainage time only takes 5 minutes. Experiments have shown that introducing high-pressure airflow during water flushing system drainage can significantly improve drainage efficiency, and the high-pressure fan generates hot air up to 64℃, which is more conducive to preventing freezing during winter drainage.
