 JN15-24/31.5型戶內高壓接地開關（以下簡稱接地開關）是我公司根據(jù)市場需要設計開發(fā)的新型接地開關，適用于戶內312kv三相交流50（60）hz的電力系統(tǒng)內和各型號高壓開關柜配套使用，亦可作為高壓電器設備檢修時接地用。
   該接地開關結構簡單緊湊、重量輕、操作靈活、安裝方便、動熱穩(wěn)定好，是jn4-10接地開關的理想換代產(chǎn)品。
二、環(huán)境條件
   1、適用于以下環(huán)境條件
      2.1.1海拔高度不超過1000米；
      2.1.2環(huán)境溫度不高于40℃，不低于-10℃；
      2.1.3相對濕度日平均不大于95，月平均不大于90；
      2.1.4地震烈度不超過8度。
   2、不適用于下列場所
      2.2.1安裝場所在有嚴重影響接地開關絕緣和導電能力的氣體、蒸汽、化學性沉淀、煙霧、灰塵污垢以及其侵蝕物質；
      2.2.2安裝場所存在頻繁劇烈的震動。
三、結構和工作原理
   1、主要結構
      接地開關有支架、接地刀裝配、靜觸頭、傳感器、軸、拐臂、壓簧、導電套管、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
      當操作操動機構使接地開關合閘時，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動，并使接地刀壓簧通過死點，壓簧儲能結束，以備下次合閘。
      接地開關和合閘速度與人的操作速度無關。

產(chǎn)品英文解釋：

JN15-24/31.5 type indoor hv grounding switch (hereinafter referred to as the grounding switch) according to the needs of the market, design and development of new type grounding switch, suitable for indoor 312 kv three-phase ac 50 (60) hz power system in various models and high-voltage switchgear supporting the use, can be as high voltage apparatus equipment maintenance with grounding.
This grounding switch simple and compact structure, light weight, flexible operation, easy installation, dynamic thermal stability is good, is jn4-10 grounding switch ideal replacement.
Second, environmental conditions
1, apply to the environmental conditions
2.1.1 altitude does not exceed 1000 m;
2.1.2 environment temperature is not higher than 40 ℃, no less than-10 ℃;
2.1.3 relative humidity daily average is not more than 95, on average is not more than 90;
2.1.4 seismic intensity does not exceed 8 degrees.
2, does not apply to the following places
2.2.1 installation in places that have serious impact grounding switch insulation and conductive ability of gas, steam, chemical precipitation, smoke, dust, dirt and its explosion erosion substance;
2.2.2 installation place frequently violent vibration there.
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.
