40.5（KV） 雷电冲击耐压 210 三、结构和工作原理 1、主要结构
接地开关有支架、接地刀装配、静触头、传感器、轴、拐臂、压簧、导电套管、软连接组成。注：支架由薄钢板弯曲后焊接成部件，其余均为组装式零部件。
2、工作原理
当操作操动机构使接地开关合闸时，作为力矩使主轴克服阻力矩，带动拐臂沿合闸方向转动，并使接地刀上的操纵杆通过压簧死点，压簧释放能量，使接地开关快速合闸，在合闸位置。接地刀组件上的接地刀通过碟形弹簧和静触头的凸缘部（刀口）牢固可靠地接触。
分闸操作时，作用力矩使主轴克服主力矩及弹簧力，带动拐臂沿分闸方向转动，并使接地刀压簧通过死点，压簧储能结束，以备下次合闸。
接地开关和合闸速度与人的操作速度无关。

work principle 1, the main structure Grounding switch have stents,
grounding knife assembly, static contact head, sensors, shaft, turn
the compression spring, arm, conductive casing, the soft to form.
Note: thin plate after stent by bending welding into parts, the
others all for assembly type parts. 2, the working principle When
operating operation structure make grounding switch off, as torque
make main shaft overcome resistance torque, drive along the
direction turn arm feeder, and ground on the knife through a
joystick compression spring dead spots, the compression spring
release energy, make grounding switch off quickly, in close brake
position. Grounding the knife knife components grounding through
disc springs and contacts of the flange department (blade) with
sturdy and reliable. Break-brake operations, role to overcome the
main shaft torque torque and spring force, drive along the turn arm
break-brake direction, and make the compression spring through the
dead point grounding knife, the compression spring energy storage
end, with the stores of time off. Grounding switch and close brake
speed and the operation speed have nothing to do. Shanghai people
on electric Co., LTD. Is a specialized production, grounding
switch, load switch, isolating switch, fuse, and other series, we
in order to let you use the lowest price to get the best of
products, our company parts were their production, achieve a
complete set of production effect, the price is low cost greatly,
so the price and quality of you can be at ease completely. The
