The five preventions of high voltage switch cabinet of complete electrical equipment manufacturer are as follows:
1、避免带负荷分、合阻隔开关。（断路器、负荷开关、接触器合闸状况不能操作阻隔开关。）
1. Avoid opening and closing the barrier switch with load. (the circuit breaker, load switch and contactor cannot operate the blocking switch under closing condition.)
2、避免误分、误合断路器、负荷开关、接触器。（只要操作指令与操作设备对应才干对被操作设备操作）
2. Avoid opening and closing circuit breaker, load switch and contactor by mistake. (as long as the operation instruction corresponds to the operating equipment, the operated equipment can be operated.)
3、避免接地开关处于闭合方位时关合断路器、负荷开关。（只要当接地开关处于分闸状况，才干合阻隔开关或手车才干进作业方位，才干操作断路器、负荷开关闭合）
3. Avoid closing the circuit breaker and load switch when the grounding switch is in the closed position. (as long as the grounding switch is in the opening state, the blocking switch can be closed or the handcart can enter the operation position, and the circuit breaker and load switch can be closed.)
4、避免在带电时误合接地开关。（只要在断路器分闸状况，才干操作阻隔开关或手车才干从作业方位退试验方位，才干合上接地开关）
4. Avoid closing the grounding switch by mistake when electrified. (only when the circuit breaker is open, the barrier switch or handcart can be operated, the operation position can be retreated to the test position, and the grounding switch can be closed.)
5、避免误入带电间隔。（只要隔室不带电时，才干开门进入隔室）变配电室的“五防”即防火、防水、防雷、防雪、防小动物。“一通”即保持通风杰出。
5. Avoid entering the live interval by mistake. (only when the compartment is not electrified, the door can be opened to enter the compartment.) the "five preventions" of the power transformation and distribution room are fire prevention, waterproof, lightning protection, snow prevention and small animals prevention. "One pass" means keeping ventilation.
电气“五防”功能的完成成了电力出产的重要措施之一。跟着电网的不断发展，技术的不断更新，防误装置得到不断改进和完善。
The completion of electrical "five prevention" function has become one of the important measures for the safe production of electric power. With the continuous development of the power grid and the continuous updating of technology, the error prevention device has been continuously improved and perfected.
高压配电柜又可称为高压开关柜，是指用于电力系统发电、输电、配电、电能转换和消耗中起通断、操控或保护等效果，高压开关制造业是输变电设备制造业的重要组成部分，在整个电力工业中占有非常重要的地位。
High voltage distribution cabinet, also known as high-voltage switch cabinet, is used for power generation, transmission, distribution, energy conversion and consumption of power system, such as on-off, control or protection effect. High voltage switch manufacturing industry is an important part of power transmission and transformation equipment manufacturing industry, which occupies a very important position in the whole power industry.
电气成套设备一般电压等级在3.6KV~550KV的电器产品，首要包括高压断路器、高压阻隔开关与接地开关、高压负荷开关、高压主动重合与分段器，高压操作机构、高压防爆配电装置和高压开关柜等几大类。
The general voltage level of electrical equipment is 3.6kV ~ 550kV, mainly including high-voltage circuit breaker, high-voltage barrier switch and grounding switch, high-voltage load switch, high-voltage active reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switch cabinet.
