一种±660kV直流输电线路用金属氧化物避雷器装置
摘要：
本发明提供一种±660kV直流输电线路用金属氧化物避雷器装置，包括避雷器本体、高压端电极、低压端电极、绝缘底座、计数器、专用连接板、V串复合绝缘子、夹具、可调工字钢和角钢支架。高压端电极通过专用连接板与输电导线悬垂联板连接，低压端电极固定在避雷器本体一端，避雷器本体另一端通过绝缘底座、可调工字钢和角钢支架固定在输电线路杆塔上，避雷器本体中部通过V串复合绝缘子固定于输电线路杆塔。本发明能满足±660kV直流输电线路在雷击状态下安全输电的需要，避免了由于雷击造成停电事故的缺点。
摘要（英）：

The invention provides a metal oxide arrester device for a +/-660kV DC transmission line. The metal oxide arrester device comprises an arrester body, a high-voltage terminal electrode, a low-voltage terminal electrode, an insulating base, a counter, a special connection plate, V strings of composite insulators, a clamp, an adjustable I-beam and an angle iron support, wherein the high-voltage terminal electrode is connected with a transmission conductor suspension yoke plate through the special connection plate; the low-voltage terminal electrode is fixed at one end of the arrester body and the other end of the arrester body is fixed on a transmission line tower through the insulating base, the adjustable I-beam and the angle iron support; and the middle part of the arrester body is fixed on the transmission line tower through the V strings of composite insulators. The metal oxide arrester device can meet the security transmission requirements of the +/-660kV DC transmission line in a lightning stroke state; and the disadvantages of a power failure caused by a lightning stroke are avoided.
