现有直流融冰装置功能检测性试验方法将输出电压、电流作为单一因素分别检测,不能有效模拟融冰装置带线路运行时的实际工况,检测结果缺乏可靠性.基于全压大电流检测试验方法,提出水即为导电介质又作散热介质的模拟负载设计思路,制作了等效负载装置,在1/100的缩比功率下,开展了等效负载验证性试验:在30 min通流时间内,采用多路温度巡检仪测量并记录了散流电极极板温度;同时监测回路电压与电流,总结了负载装置电阻随通流时间增加的变化规律;通过不同水流初速条件下的等效负载试验,确定当入口流速达到8.8m3/h时,极板温度和装置电阻能在通流时间内达到稳定,满足工程检测性试验要求,验证了等效负载可行性和该检测试验方法的工程推广价值.,Conventional test methods for DC deicer’s function detection regard the output voltage and current as separate detection targets,which cannot represent the real operational condition and lead to inconvincible conclusions.In this paper,a high-power analog load is made while the idea of using water both as conductive and cooling medium is presented.Under 1/100 scaled power,confirmatory tests are conducted:In 30 mins,a multi-channel temperature logging device is used to measure and record the temperature of plate electrodes;with the circuit current and voltage monitoring,variation trend of the resistance of the load device is studied.When the inlet flow rate reaches 8.8 m3/h,temperature of electrodes and resistance of load device achieve stability during the test,which verifies the feasibility and t promotional value of the test method.
