山东电气成套中高压开关柜的五项防误闭锁功能及实现方法

Five anti misoperation locking functions and implementation methods of Shandong Electric's complete set of medium and high voltage switchgear

高压开关柜必须具备五项基本防误闭锁功能有哪些:

What are the five basic anti misoperation locking functions that high-voltage switchgear must have

1.防止误分、合断路器;

1. Prevent accidental opening and closing of circuit breakers;

2.防止带负荷分、合隔离开关(隔离插头);

2. Prevent the opening and closing of isolation switches (isolation plugs) under load;

3.防止带电挂接地线(合接地开关);

3. Prevent hanging grounding wires when live (close the grounding switch);

4.防止带接地线(接地开关合闸状态)合断路若苦;

4. Prevent the use of a grounding wire (when the grounding switch is in the closed state) to avoid breaking the circuit;

5.防止误入带电间隔(隔室)。高压开关柜实现五项基本防误闭锁功能的方法主要有以下几种:

5. Prevent entering live compartments by mistake. The main methods for achieving the five basic anti misoperation locking functions of high-voltage switchgear are as follows:

(1)机械联锁

(1) Mechanical interlocking

联锁方法简单、可靠、直接、有效,一般用于高压开关柜断路器-隔离开关-接地开关-柜门之间的联锁,应优先采用。但柜与柜之间的联锁很难实现。

The interlocking method is simple, reliable, direct, and effective, generally used for interlocking between high-voltage switchgear circuit breakers, isolating switches, grounding switches, and cabinet doors, and should be prioritized. But interlocking between cabinets is difficult to achieve.

(2)电气联锁

(2) Electrical interlocking

联锁方法容易实现,联锁功能可以做的很完善,但如果辅助开关、继电器等电器接点切换不灵或粘连则会造成联锁功能丧失或紊乱。这种联锁方法一般作为机械联锁的辅助手段,实现双重联锁。

The interlocking method is easy to implement, and the interlocking function can be very complete. However, if the auxiliary switches, relays, and other electrical contacts are not switched properly or stuck, it will cause the loss or disorder of the interlocking function. This interlocking method is generally used as an auxiliary means of mechanical interlocking to achieve dual interlocking.

(3)电磁锁

(3) Electromagnetic lock

联锁方法简单、有效,但有一定局限性,一般用于柜门闭锁。解锁钥匙必须严格管理和慎用。

The interlocking method is simple and effective, but has certain limitations and is generally used for cabinet door locking. The universal unlocking key must be strictly managed and used with caution.

(4)微机闭锁

(4) Microcomputer interlocking

软件设计完善,防误功能齐全,但成本较高。

The software design is complete and error prevention functions are complete, but the cost is relatively high.

(5)机械程序锁

(5) Mechanical program lock

联锁方法简单、可靠、直接、有效,特别适合多台柜之间的联锁。

The interlocking method is simple, reliable, direct, and effective, especially suitable for interlocking between multiple cabinets.
