一、高低壓配電柜的基本介紹
1、 Basic introduction of high and low voltage distribution cabinet
高低壓配電柜顧名思義就是電力供電系統(tǒng)中用于進行電能分配、控制、計量以及連接線纜的配電設(shè)備,一般供電局、變電所都是用高壓開關(guān)柜,然后經(jīng)變壓器降壓低壓側(cè)引出到低壓配電柜。
As the name suggests, high and low voltage distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in power supply system. Generally, high voltage switch cabinet is used in Power Supply Bureau and substation, and then led to low voltage distribution cabinet through transformer step-down low voltage side.
低壓配電柜在到各個用電的配電盤,控制箱,開關(guān)箱,里面就是通過將一些開關(guān)、斷路器、熔斷器、按鈕、指示燈、儀表、電線之類保護器件組裝成一體達到設(shè)計功能要求的配電裝置的設(shè)備。俗稱:高低壓開關(guān)柜或高低壓電氣成套設(shè)備。
The low-voltage distribution cabinet in the distribution board, control box, switch box, which is through some switches, circuit breakers, fuses, buttons, indicator lights, instruments, wires and other protective devices assembled into one to achieve the design function requirements of the distribution device equipment. Commonly known as: high and low voltage switchgear or high and low voltage electrical equipment.
二、電氣成套:各個配電柜的作用
2、 Electrical complete set: function of each distribution cabinet
高壓進線柜、計量柜、高壓出線柜、低壓進線柜、電容柜、低壓出線柜,這些配電柜是配電室的常規(guī)配置,不管高壓還是低壓都是按一定的功能組合在一起。
High voltage incoming cabinet, metering cabinet, high voltage outgoing cabinet, low voltage incoming cabinet, capacitor cabinet, 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.
(1)高壓進線柜:它是分斷高壓進線電源的高壓柜,其實不是真正的進線柜,進線一般不是接在這臺柜子上,而是接在隔離柜上的,但它有斷路器(真空)能分斷進線電源所以才叫進線柜。
(1) High voltage incoming cabinet: it is a high-voltage cabinet to cut off 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 has a circuit breaker (vacuum) to cut off the incoming power supply, so it is called incoming cabinet.
(2)計量柜:顧名思義就是用來裝電度表的,準確計量你用多少電的柜子,該柜子除了PT、CT就沒有什么大的元件了。
(2) Metering cabinet: as the name suggests, it is used to install watt hour meter, which can accurately measure how much electricity you use. Except Pt and CT, the cabinet has no big components.
(3)高壓出線柜:他的作用是用來分配和輸送電能的,他一般帶的變壓器或是高壓用電設(shè)備(電動機)及高壓補償設(shè)備等。
(3) High voltage outlet cabinet: its function is to distribute and transmit electric energy. Generally, it is equipped with transformer or high-voltage electrical equipment (motor) and high-voltage compensation equipment.
(4)低壓進線柜:一般是從變壓器下來的一臺柜子,也稱為低總柜,用來控制下面所有的用電設(shè)備,他的總開關(guān)一般都采用框架斷路器。
(4) Low voltage incoming cabinet: it is generally a cabinet from the transformer, also known as low main cabinet, which is used to control all the electrical equipment below. Its main switch generally adopts frame circuit breaker.
(5)電容柜:他的作用,用來補償用電質(zhì)量,提高功率因數(shù)!
(5) Capacitor cabinet: its function is to compensate power quality and improve power factor!
(6)低壓出線柜:他的作用是用來分配和輸送電能,他和高壓不同的是基本直接到用電設(shè)備了,開關(guān)一般采用塑殼斷路器。
(6) Low voltage outlet cabinet: its function is to distribute and transmit electric energy. Different from high voltage, it is basically directly connected to electrical equipment. Moulded case circuit breaker is generally used as switch.
