三、結(jié)構(gòu)和工作原理
   1、主要結(jié)構(gòu)
      接地開關(guān)有支架、接地刀裝配、靜觸頭、傳感器、軸、拐臂、壓簧、導(dǎo)電套管、軟連接組成。注：支架由薄鋼板彎曲后焊接成部件，其余均為組裝式零部件。
   2、工作原理
      當(dāng)操作操動機(jī)構(gòu)使接地開關(guān)合閘時，作為力矩使主軸克服阻力矩，帶動拐臂沿合閘方向轉(zhuǎn)動，并使接地刀上的操縱桿通過壓簧死點，壓簧釋放能量，使接地開關(guān)快速合閘，在合閘位置。接地刀組件上的接地刀通過碟形彈簧和靜觸頭的凸緣部（刀口）牢固可靠地接觸。
      分閘操作時，作用力矩使主軸克服主力矩及彈簧力，帶動拐臂沿分閘方向轉(zhuǎn)動，并使接地刀壓簧通過死點，壓簧儲能結(jié)束，以備下次合閘。
      接地開關(guān)和合閘速度與人的操作速度無關(guān)。

Three, structure and 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.
