山東電氣成套中高壓開關(guān)柜的五項防誤閉鎖功能及實現(xiàn)方法

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

高壓開關(guān)柜必須具備五項基本防誤閉鎖功能有哪些:

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

1.防止誤分、合斷路器;

1. Prevent accidental opening and closing of circuit breakers;

2.防止帶負(fù)荷分、合隔離開關(guān)(隔離插頭);

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

3.防止帶電掛接地線(合接地開關(guān));

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

4.防止帶接地線(接地開關(guān)合閘狀態(tài))合斷路若苦;

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

5.防止誤入帶電間隔(隔室)。高壓開關(guān)柜實現(xiàn)五項基本防誤閉鎖功能的方法主要有以下幾種:

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)機(jī)械聯(lián)鎖

(1) Mechanical interlocking

聯(lián)鎖方法簡單、可靠、直接、有效,一般用于高壓開關(guān)柜斷路器-隔離開關(guān)-接地開關(guān)-柜門之間的聯(lián)鎖,應(yīng)優(yōu)先采用。但柜與柜之間的聯(lián)鎖很難實現(xiàn)。

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)電氣聯(lián)鎖

(2) Electrical interlocking

聯(lián)鎖方法容易實現(xiàn),聯(lián)鎖功能可以做的很完善,但如果輔助開關(guān)、繼電器等電器接點切換不靈或粘連則會造成聯(lián)鎖功能喪失或紊亂。這種聯(lián)鎖方法一般作為機(jī)械聯(lián)鎖的輔助手段,實現(xiàn)雙重聯(lián)鎖。

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)電磁鎖

(3) Electromagnetic lock

聯(lián)鎖方法簡單、有效,但有一定局限性,一般用于柜門閉鎖。解鎖鑰匙必須嚴(yán)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)微機(jī)閉鎖

(4) Microcomputer interlocking

軟件設(shè)計完善,防誤功能齊全,但成本較高。

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

(5)機(jī)械程序鎖

(5) Mechanical program lock

聯(lián)鎖方法簡單、可靠、直接、有效,特別適合多臺柜之間的聯(lián)鎖。

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