    山東電氣成套中高壓開關柜的五項防誤閉鎖功能及實現方法

    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.防止帶負荷分、合隔離開關(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);

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

    4.防止帶接地線(接地開關合閘狀態)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)。高壓開關柜實現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)機械聯鎖

    (1) Mechanical interlocking

    聯鎖方法簡單、可靠、直接、有效,一般用于高壓開關柜斷路器-隔離開關-接地開關-柜門之間的聯鎖,應優先采用。但柜與柜之間的聯鎖很難實現。

    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)電氣聯鎖

    (2) Electrical interlocking

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

    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)微機閉鎖

    (4) Microcomputer interlocking

    軟件設計完善,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)機械程序鎖

    (5) Mechanical program lock

    聯鎖方法簡單、可靠、直接、有效,特別適合多臺柜之間的聯鎖。

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