The five preventions of high voltage switch cabinet of complete electrical equipment manufacturer are as follows:
1、避免帶負荷分、合阻隔開關。（斷路器、負荷開關、接觸器合閘狀況不能操作阻隔開關。）
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、避免誤分、誤合斷路器、負荷開關、接觸器。（只要操作指令與操作設備對應才干對被操作設備操作）
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、避免接地開關處于閉合方位時關合斷路器、負荷開關。（只要當接地開關處于分閘狀況，才干合阻隔開關或手車才干進作業方位，才干操作斷路器、負荷開關閉合）
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、避免在帶電時誤合接地開關。（只要在斷路器分閘狀況，才干操作阻隔開關或手車才干從作業方位退試驗方位，才干合上接地開關）
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、避免誤入帶電間隔。（只要隔室不帶電時，才干開門進入隔室）變配電室的“五防”即防火、防水、防雷、防雪、防小動物。“一通”即保持通風杰出。
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.
電氣“五防”功能的完成成了電力出產的重要措施之一。跟著電網的不斷發展，技術的不斷更新，防誤裝置得到不斷改進和完善。
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.
高壓配電柜又可稱為高壓開關柜，是指用于電力系統發電、輸電、配電、電能轉換和消耗中起通斷、操控或保護等效果，高壓開關制造業是輸變電設備制造業的重要組成部分，在整個電力工業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.
電氣成套設備一般電壓等級在3.6KV~550KV的電器產品，首要包括高壓斷路器、高壓阻隔開關與接地開關、高壓負荷開關、高壓主動重合與分段器，高壓操作機構、高壓防爆配電裝置和高壓開關柜等幾大類。
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.
