Description

一种用于耐张塔的单相电阻型无源防冰融冰控制设备 一、技术领域
本发明涉及电力输送线路的耐张塔，特别是用于耐张塔的防冰融冰控制设备。
二、背景技术
在电力输送线路中，耐张塔的垂直荷载决定电力线路的使用安全与寿命。在寒冷的冬季，耐张塔的防冰融冰尤为重要。
专利号：ZL201811489790.9《线间无损单相分流器与设计和控制方法》给出了一种线间无损单相分流器的设计和控制方法。通过计算变压器线圈匝比，在微处理器对切换开关的控制下使导体电流刚好满足防冰融冰需求，精准控制电流、精准控制防冰融冰。本方法分流器可在正常输电和防冰融冰双重模式下工作，操作简单可靠。但是，存在如下的不足：有载分接开关结构复杂，价格昂贵，而且控制不方便，不便于耐张塔使用；分压变压器承担的电压过高，导致制造成本高；整体重量较重，对安装的耐张塔力学性能要求高，对于存量输电线路，有的需要对耐张塔加固。
专利号201921929880.5《无源智能融冰控制设备》解决了智能融冰设备在使用过程中取电困难的难题，通过传感主体温度变化改变电阻的变化，自动启动输电导线融冰、在感知融冰结束后自动停止融冰，保持输电导线温度在合适范围。但是存在两个不足：无源温度传感器与无源温控电阻分离设计，影响设备可靠性；电阻上会散发较大热量，使用过程中需要较好的散热；而这个热量属于损耗。
