高低压配电柜基本知识有哪些?

发布时间:2021-11-09 来源:http://www.tongyuhengcheng.com/ 浏览量:

高低压配电柜顾名思义就是电力供电系统中用于进行电能分配、控制、计量以及连接线缆的配电设备,一般供电局、变电所都是用高压开关柜,然后经变压器降压低压侧引出到低压配电柜。
As the name suggests, high and low voltage distribution cabinet is the distribution equipment used for power distribution, control, metering and connecting cables in the power supply system. Generally, high-voltage switchgear is used in power supply bureaus and substations, and then led to the low-voltage distribution cabinet through the step-down low-voltage side of the transformer.
低压配电柜在到各个用电的配电盘,控制箱,开关箱,里面就是通过将一些开关、断路器、熔断器、按钮、指示灯、仪表、电线之类保护器件组装成一体达到设计功能要求的配电装置的设备。俗称:高低压开关柜或高低压电气成套设备。
The low-voltage distribution cabinet is the equipment of the power distribution device that meets the design functional requirements by assembling some protective devices such as switches, circuit breakers, fuses, buttons, indicator lights, instruments and wires into one. Commonly known as: high and low voltage switchgear or high and low voltage electrical complete equipment.
各个配电柜的作用
Function of each distribution cabinet
高压进线柜、计量柜、高压出线柜、低压进线柜、电容柜、低压出线柜,这些配电柜是配电室的常规配置,不管高压还是低压都是按一定的功能组合在一起。
High voltage incoming cabinet, metering cabinet, high voltage outgoing cabinet, low voltage incoming cabinet, capacitor cabinet and low voltage outgoing cabinet. These distribution cabinets are the conventional configuration of the distribution room. Whether high voltage or low voltage are combined according to certain functions.
电气成套
(1)高压进线柜:它是分断高压进线电源的高压柜,其实不是真正的进线柜,进线一般不是接在这台柜子上,而是接在隔离柜上的,但它有断路器(真空)能分断进线电源所以才叫进线柜。
(1) High voltage incoming cabinet: it is a high-voltage cabinet that disconnects the high-voltage incoming power supply. In fact, it is not a real incoming cabinet. The incoming line is generally not connected to this cabinet, but to the isolation cabinet. However, it is called the incoming cabinet because it has a circuit breaker (vacuum) that can disconnect the incoming power supply.
(2)计量柜:顾名思义就是用来装电度表的,准确计量你用多少电的柜子,该柜子除了PT、CT就没有什么大的元件了。
(2) Metering cabinet: as the name suggests, it is a cabinet used to install watt hour meters and accurately measure how much electricity you use. There are no large components in the cabinet except Pt and CT.
(3)高压出线柜:他的作用是用来分配和输送电能的,他一般带的变压器或是高压用电设备(电动机)及高压补偿设备等。
(3) High voltage outgoing cabinet: it is used to distribute and transmit electric energy. It usually carries transformers or high-voltage electrical equipment (motors) and high-voltage compensation equipment.
(4)低压进线柜:一般是从变压器下来的第一台柜子,也称为低总柜,用来控制下面所有的用电设备,他的总开关一般都采用框架断路器。
(4) Low voltage incoming cabinet: it is generally the first cabinet from the transformer, also known as low main cabinet, which is used to control all the following electrical equipment. Its main switch generally adopts frame circuit breaker.
(5)电容柜:他的作用,用来补偿用电质量,提高功率因数!
(5) Capacitor cabinet: its function is to compensate the power quality and improve the power factor!
(6)低压出线柜:他的作用是用来分配和输送电能,他和高压不同的是基本直接到用电设备了,开关一般采用塑壳断路器。
(6) Low voltage outgoing cabinet: its function is to distribute and transmit electric energy. Unlike high voltage, it is basically directly to electrical equipment. The switch generally adopts molded case circuit breaker.
