?JN15-24/31.5型户内高压接地开关（以下简称接地开关）是我公司根据市场需要设计开发的新型接地开关，适用于户内312kv三相交流50（60）hz的电力系统内和各型号高压开关柜配套使用，亦可作为高压电器设备检修时接地用。
?? 该接地开关结构简单紧凑、重量轻、操作灵活、安装方便、动热稳定好，是jn4-10接地开关的理想换代产品。
二、环境条件
?? 1、适用于以下环境条件
????? 2.1.1海拔高度不超过1000米；
????? 2.1.2环境温度不高于40℃，不低于-10℃；
????? 2.1.3相对湿度日平均不大于95，月平均不大于90；
????? 2.1.4地震烈度不超过8度。
?? 2、不适用于下列场所
????? 2.2.1安装场所在有严重影响接地开关绝缘和导电能力的气体、蒸汽、化学性沉淀、烟雾、灰尘污垢以及其爆炸侵蚀物质；
????? 2.2.2安装场所存在频繁剧烈的震动。
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。

产品英文解释：

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.
