技术领域technical field
本发明涉及电压输电技术领域，特别是一种用于八分裂导线的高压输电线路融冰装置。The invention relates to the technical field of voltage transmission, in particular to a high-voltage transmission line ice-melting device for eight-split conductors.
背景技术Background technique
在冬季低温度、高湿度的环境中，高压电力输电线路会发生覆冰现象，严重覆冰导致输电线路杆塔倒塌、导线断线等影响电力系统安全可靠运行的重大事故，引起电网大面积停电，严重影响工农业生产和人民生活，并造成巨大经济损失。In the environment of low temperature and high humidity in winter, high-voltage power transmission lines will be covered with icing. Severe icing will lead to major accidents such as the collapse of transmission line towers and broken wires that affect the safe and reliable operation of the power system, causing large-scale power outages in the power grid. Seriously affect industrial and agricultural production and people's lives, and cause huge economic losses.
高压输电线路防冰、融冰和除冰一直是国内外关注的焦点。现有的高压输电线路除冰防冰技术尚不成熟，不能满足大面积防冰除冰的要求，部分除冰技术虽可在工程中应用，但需在外加设备或人工操作指导下进行。如公开号CN101527442A的中国发明专利公布说明书所公开的一种多根导线的防冰输电线路，它是在多根导线输电线路的两端增加融冰开关，不需要融冰时各导线均正常通电，覆冰后需要融冰时中断供电，采取手动操作开关的方式，使一根导线传输电流，其余导线断开，手动操作逐步使各导线的冰层融化。该方法需要增设开关装置，改变输电线路的结构，融冰过程必须中断供电，融冰存在安全隐患且操作极其不方便，融冰成本高，融冰启动和终止均需人为主观干预，不能区别对待不同程度的覆冰线段和实现实时防冰，对于超高压线路用开关闸分合导线不可行，特别是不能满足特高压分裂导线的防冰；又如公开号CN101459327的中国发明专利所公开的一种多分裂输电线路自动融冰方法及其专用开关，它是采用在覆冰输电线路两端变电站安装专用开关，然后人工遥控发出指令，使专用开关发生动作实现输电线路电流全部转移至待融冰的子导线，该子导线发热、融冰，该发明专利需要人工判断现场线路是否存在覆冰，并需电力调度部门配合调节线路负荷，最后在现场人工遥控发出融冰指令，无法实现根据覆冰程度的需要分区段和实时智能融冰，对于微气候微气象等局部覆冰区段技术人员很难赶到现场观测覆冰情况和发出融冰指令。Anti-icing, melting and deicing of high-voltage transmission lines have always been the focus of attention at home and abroad. The existing deicing and anti-icing technology for high-voltage transmission lines is still immature and cannot meet the requirements of large-area anti-icing and deicing. Although some deicing technologies can be applied in engineering, they need to be carried out under the guidance of external equipment or manual operation. A kind of anti-icing power transmission line of multiple wires disclosed in the Chinese invention patent publication specification with publication number CN101527442A, it is to add ice-melting switches at both ends of the power transmission line of multiple wires, and each wire is normally energized when it does not need to melt ice , When the ice needs to be melted after the ice is covered, the power supply is interrupted, and the manual operation switch is adopted to make one wire transmit current, and the other wires are disconnected, and the manual operation gradually melts the ice layer of each wire. This method needs to add switchgear and change the structure of the transmission line. The power supply must be interrupted during the ice melting process. There are safety hazards in ice melting and extremely inconvenient operation. The cost of ice melting is high. Different degrees of ice-coated line sections and real-time anti-icing are not feasible for the switch breaker wires used in ultra-high voltage lines, especially the anti-icing of UHV split wires cannot be satisfied; A multi-split transmission line automatic melting ice method and its special switch, which is to install special switches in the substations at both ends of the ice-covered transmission line, and then manually remote control to issue instructions to make the special switch move to realize the transfer of all currents of the transmission line to ice-melting The sub-conductor of the sub-conductor, the sub-conductor generates heat and melts ice. This invention patent needs to manually judge whether the on-site line is covered with ice, and needs the power dispatching department to cooperate with the adjustment of the line load. It is difficult for technicians in local ice-covered sections such as micro-climate and micro-meteorology to rush to the scene to observe the ice-covered situation and issue ice-melting instructions.
