按断路器安装方式

Press the circuit breaker installation method

按断路器安装方式分为移开式(手车式)和固定式

According to the installation mode of the circuit breaker, it can be divided into movable type (handcart type) and fixed type.

(1)移开式或手车式(用Y表示)：表示柜内的主要电器元件(如:断路器)是安装在可抽出的手车上的，由于手车柜有很好的互换性,因此可以大大提高供电的可靠性，常用的手车类型有:隔离手车、计量手车、断路器手车、PT手车、电容器手车和所用变手车等。

(1) displaced or handcart type (expressed in Y): the main electrical components in the cabinet (such as the circuit breaker) are installed on the removable handcart, and the reliability of the power supply can be greatly improved because of the good interchangeability of the handcart cabinet. The common types of handsets are separated from the hand, the measuring handcart, the circuit breaker handcart, the PT handcart, and the capacitance. The wagon and the handcart used.

(2)固定式(用G表示): 表示柜内所有的电器元件(如:断路器或负荷开关等)均为固定式安装的，固定式开关柜较为简单经济。

(2) fixed type (expressed in G): all of the electrical components in the cabinet (such as circuit breaker or load switch etc.) are fixed and fixed, and the fixed switch cabinet is simple and economical.

按安装地点

According to the place of installation

按安装地点分为户内和户外

It is divided into indoor and outdoor by the place of installation

(1)用于户内(用N表示);表示只能在户内安装使用。

(1) for indoor (expressed in N); it can only be installed indoors.

(2)用于户外(用W表示);表示可以在户外安装使用。

(2) used for outdoor (expressed in W); it can be installed and used outdoors.

按柜体结构

According to the structure of the cabinet

按柜体结构可分为金属封闭铠装式开关柜、金属封闭间隔式开关柜﹑金属封闭箱式开关柜和敞开式开关柜四大类

According to the structure of cabinet, it can be divided into four categories: metal enclosed armoured switchgear, metal enclosed spaced switchgear, metal enclosed box switch cabinet and open switchgear.

(1)金属封闭铠装式开关柜(用字母K来表示)主要组成部件(例如：断路器、互感器、母线等)分别装在接地的用金属隔板隔开的隔室中的金属封闭开关设备。

(1) metal enclosed armored switchgear (used by letter K) the main components (such as circuit breakers, transformers, busbars, etc.) in a metal enclosed compartment separated by metal isolators.

(2)金属封闭间隔式开关柜(用字母J来表示)与铠装式金属封闭开关设备相似，其主要电器元件也分别装于单独的隔室内，但具有一个或多个符合一定防护等级的非金属隔板。

(2) the metal closed spacer switchgear (represented by the letter J) is similar to the armoured metal closed switchgear. Its main electrical components are also installed separately in the separate compartment, but have one or more non-metallic separators that conform to a certain level of protection.

(3)金属封闭箱式开关柜(用字母X来表示)开关柜外壳为金属封闭式的开关设备。

(3) metal enclosed box switchgear (expressed by letter X). The enclosure of switchgear is a metal enclosed switchgear.

(4)敞开式开关柜，无保护等级要求，外壳有部分是敞开的开关设备。

(4) the open type switchgear has no requirement of protection level, and the outer part of the housing is an open switchgear.

高压配电柜中的“电气五防”功能指的是什么？

What is the function of electrical five protection in high voltage switchgear?

高压开关柜的“五防”也叫“五防一通”，装置一般可分为机械、电气和综合三类五项防止电气误操作的内容，简称“五防”，是确保设备和人身安全、防止误操 作的重要措施。

The "five defense" of the high voltage switchgear is also called "five anti one". The device can be divided into three categories, mechanical, electrical and comprehensive five items to prevent electrical misoperation. It is referred to as "five defense", which is an important measure to ensure the safety of the equipment and the human body and prevent the misoperation.

高压开关柜的五防为：

The five prevention of high voltage switchgear is:

1、防止带负荷分、合隔离开关。（断路器、负荷开关、接触器合闸状态不能操作隔离开关。）

1, prevent load and isolation switch with load. The circuit breaker, load switch and contactor can't operate isolating switch when closing state.

2、防止误分、误合断路器、负荷开关、接触器。（只有操作指令与操作设备对应才能对被操作设备操作）

2, prevent misoperation and mismatch of circuit breaker, load switch and contactor. (only operation instruction corresponds to operation device to operate device).

3、防止接地开关处于闭合位置时关合断路器、负荷开关。（只有当接地开关处于分闸状态，才能合隔离开关或手车才能进至工作位置，才能操作断路器、负荷开关闭合）

3, prevent the earthing switch from being closed, closing the circuit breaker and load switch. (only when the earthing switch is in the state of closing, can the isolating switch or handcart enter the working position to operate the circuit breaker and the load switch close).

4、防止在带电时误合接地开关。（只有在断路器分闸状态，才能操作隔离开关或手车才能从工作位置退至试验位置，才能合上接地开关）

4, prevent the fault of grounding switch when charged. Only when the circuit breaker is open, can the isolating switch or handcart be removed from the working position to the test location to close the ground switch.

5、防止误入带电间隔。（只有隔室不带电时，才能开门进入隔室） 变配电室的“五防”即防火、防水、防雷、防雪、防小动物。“一通”即保持通风良好。

5, prevent the charging interval. (only when the compartment is not charged, can we open the door to enter the compartment). The "five prevention" in the power distribution room is fire protection, waterproof, lightning protection, snow protection and small animals prevention. "One way" is to keep well ventilated.
