开关柜为什么叫“成套配电装置”?

发布时间:2023-03-08 来源:http://www.tongyuhengcheng.com/ 浏览量:

常见的低压配电柜、高压配电柜其实并不是单单指配电柜本身,它实际上是我们俗称的电气成套设备,其实这种叫法是不准确的,学名应该是“成套配电装置”。那么开关柜为什么叫“成套配电装置”?下面小编为您讲解:
The common low-voltage distribution cabinet and high-voltage distribution cabinet are not only the distribution cabinet itself, but actually the electrical complete set of equipment we commonly call. In fact, this name is inaccurate, and the scientific name should be "complete set of power distribution device". So why is the switch cabinet called "complete power distribution device"? The following editor will explain to you:
成套配电装置是以断路器为主的电气设备,成套配电装置是制造厂成套供应的设备,由制造厂预先按照主接线的要求,将每一回路的电气设备高低压电器(包括控制电器、保护电器、测量电器、如断路器、隔离开关、互感器等)以及母线、载流导体、绝缘子等,装配在封闭或半封闭的金属柜中,构成各单元电路分柜,此单元电路分柜成为成套配电装置。安装时,按主接线方式,将各单元分柜(又称间隔)组合起来,就构成整个配电装置。
The complete set of power distribution device is the electrical equipment mainly based on the circuit breaker. The complete set of power distribution device is the equipment supplied by the manufacturer in a complete set. The manufacturer assembles the high and low voltage electrical equipment (including control electrical equipment, protection electrical equipment, measuring electrical equipment, such as circuit breaker, disconnector, mutual inductor, etc.), bus, current-carrying conductor, insulator, etc. of each circuit in a closed or semi-closed metal cabinet according to the requirements of the main wiring in advance, Each unit circuit sub-cabinet forms a complete set of power distribution device. During installation, each unit and sub-cabinet (also called bay) are combined according to the main wiring mode to form the whole power distribution device.
电气成套
在电器成套设备中把母线、隔离开关(高压)、刀开关(低压)、断路器(空气开关)、电压互感器、电流互感器、电力变压器、交流接触器、保护继电器(热继电器)、避雷器等组成的设备叫一次设备。由它们按照原理关系所组成的回路称为一次回路或一次方案图。
In the complete set of electrical equipment, the equipment consisting of bus, disconnector (high voltage), knife switch (low voltage), circuit breaker (air switch), voltage transformer, current transformer, power transformer, AC contactor, protective relay (thermal relay), lightning arrester, etc. is called primary equipment. The circuit composed of them according to the principle relationship is called primary circuit or primary scheme diagram.
为了使一次系统能可靠、稳定地运行,随时监视一次系统运行状态,同时能随时控制一次系统所必须配备许多其他电器元件及设备。如:测量仪表(电流表、电压表、功率因素表、功率表、频率表等)、控制信号元件(信号灯、按钮、转换开关等)、继电保护装置等。由它们按照原理关系所组成的回路称为二次回路或二次方案图。
In order to ensure the safe, reliable and stable operation of the primary system, monitor the operation status of the primary system at any time, and control the primary system at any time, many other electrical components and equipment must be equipped. Such as measuring instruments (ammeter, voltmeter, power factor meter, power meter, frequency meter, etc.), control signal elements (signal lamp, button, universal transfer switch, etc.), relay protection devices, etc. The circuit composed of them according to the principle relationship is called secondary circuit or secondary scheme diagram.
成套配电装置的特点
Characteristics of complete power distribution device
1、成套设备有金属外壳(柜体)的保护,电气设备和载流导体不易积灰,便于维护,特别是对外处的污秽地区时更为突出。
1. The complete set of equipment is protected by a metal shell (cabinet). The electrical equipment and current-carrying conductor are not easy to accumulate dust and are easy to maintain, especially in the external polluted areas.
2、成套设备易于实现系列化、标准化、具有装配质量好、速度快、运行可靠性高的特点。由于进行定型设计和制作生产,所以其结构紧凑、布局合理、缩小了体积和占地面积,降低了造价。
2. The complete set of equipment is easy to realize serialization and standardization, and has the characteristics of good assembly quality, fast speed and high operation reliability. Due to the finalization design and production, the structure is compact, the layout is reasonable, the volume and floor area are reduced, and the cost is reduced.
3、成套设备的电器安装、线路敷设与变配室的施工是分开进行的,缩短了基建的时间。
3. The electrical installation of the complete set of equipment, the line laying and the construction of the transformation and distribution room are carried out separately, which shortens the time of capital construction.
