Power terminal pole provided with high-voltage isolating switch
The invention relates to a power terminal pole provided with a high-voltage isolating switch, and belongs to the technical field of power terminal poles, the power terminal pole comprises a pole body, and a first cross arm and a second cross arm which are arranged on the pole body, the first cross arm is connected with a transformer substation side wire through a first strain insulator string, and the second cross arm is connected with a transformer substation side wire through a second strain insulator string. A second cross arm is arranged on the pole body and connected with a line side wire through a second strain insulator string, a third cross arm is arranged on the pole body and provided with a high-voltage isolation switch, and the transformer substation side wire and the line side wire are connected to the two sides of the high-voltage isolation switch through jumpers respectively. And the high-voltage isolating switch remotely receives a ground control signal to be automatically switched on and off. The high-voltage isolation switch is installed through the additionally arranged cross arm, area increase caused by arrangement of the isolation switch in a transformer substation is reduced, meanwhile, an overhead line side has an obvious disconnection point in the maintenance period of transformer substation equipment, and accidents caused by the fact that a line side power source invades a maintenance area are prevented.
本发明涉及一种装设高压隔离开关的电力终端杆，属于电力终端杆技术领域，其包括杆体，以及设置在所述杆体上的第一横担和第二横担，所述第一横担通过第一耐张绝缘子串与变电站侧导线连接，所述第二横担通过第二耐张绝缘子串与线路侧导线连接，所述杆体上设置第三横担，所述第三横担上设置高压隔离开关，所述变电站侧导线和所述线路侧导线分别通过跳线连接在所述高压隔离开关两侧，所述高压隔离开关远程接收地面控制信号进行自动开断。本发明通过增设的横担安装高压隔离开关，减少了在变电站布置隔离开关引起的面积增加，同时实现在变电站设备检修期间，架空线路侧具有明显的断开点，防治线路侧电源侵入检修区域造成事故。
