什么是高压开关柜?贵阳开关柜告诉你!

What is a high voltage switchgear? Guiyang switchboard tell you!

贵阳开关柜

高压开关柜是指用于电力系统发电、输电、配电、电能转换和消耗中起通断、控制或保护等作用,高压开关柜按作电压等级在3.6kV~550kV的电器产品,高压隔离开关与接地开关、高压负荷开关、高压自动重合与分段器,高压操作机构、高压防爆配电装置和高压开关柜等几大类。

贵州森时达电力电气有限公司High voltage switchgear is used for power generation, transmission, distribution, and consumption of electrical energy conversion, on-off control or protection function, high voltage switch cabinet is made by the voltage level of electrical products in 3。6kV~550kV, and the grounding switch, load switch, high pressure automatic reclosing and sectionalizers high-voltage isolating switch, high voltage the operating mechanism, high pressure explosion-proof power distribution equipment and high voltage switch cabinet and other categories。


1明确项目定位

1 clear project location

高压开关柜是成套的组合产品,目前国内虽有数百家生产厂商,但其核心部件仍采用进口的产品为主,如果遇到技术问题,设备维护和更换都比较麻烦,因此,在预算充裕的情况下,应尽量选择知名的品牌,由于其备货充足,遇到问题时的解决效率比较高。

贵州森时达电力电气有限公司High voltage switch cabinet is a combination product sets, although domestic hundreds of manufacturers, but its core components are still imported products, if you encounter technical problems, equipment maintenance and replacement are more trouble, therefore, in the budget situation, should try to choose well-known brands, because of its well stocked, meet the problem solving efficiency is relatively high.

2.检验资质

2. test qualification

选购前要向生产厂家索取开关柜出厂试验大纲(或要求),一般正规生产厂家都会有的,应该搞清楚主要元器件是否按图纸要求配置并选择了指定品牌,如西门子、施奈德等。

Before the purchase, we must ask the manufacturer to get the outline and request of the Switchgear Factory test. The regular manufacturers will have some. We should make sure whether the main components are allocated according to the drawing requirements and choose the designated brands, such as SIEMENS, Schneider and so on.

3.柜体材料

3。 cabinet material

高压开关柜体积较大,因此,柜体材料对价格影响很大,一般情况下,部件支架等都采用进口敷铝锌板,而门板则采用300系列优质钢板。

贵州森时达电力电气有限公司High voltage switch cabinet volume is larger, therefore, the material has great influence on the price, in general, support components are imported tibnor, but the door is the 300 series of high-quality steel plate.

4。整组柜排列

4. set of cabinets

柜体排列次序及操作面位置是制造厂考虑制作柜内隔板、终端护板、母线分段支架等问题时正确施工依据,平面布置图要与现场进出线实际位置吻合,尤其是要正确表示出柜体操作面方向,才能使高压柜到达现场后能顺利进行安装。往往起先不予重视,设备到达现场后,发觉与现场要求不符合,最后导致返工。

The order and operation position is factory problem considering the production of cabinet clapboard, terminal plate, busbar support correct construction basis, layout and site line and the actual position of anastomosis, especially to correct out gymnastics as plane direction, in order to make the high voltage cabinet arrived at the scene smoothly after installation. Often at first, no attention should be paid. After the equipment arrives at the scene, it is found that it does not conform to the requirements of the site and eventually leads to rework.

5.进出线方式

贵州森时达电力电气有限公司5. mode of import and export

贵州森时达电力电气有限公司开关柜上常规进出线基本有二种连接方式:(1)进出线电缆电缆室连接,(2)进出线由柜顶穿墙套管引出,并与母线桥架相连母线桥架再经穿墙套管与架空线连接。也有少数用户,电缆电缆架由柜顶引入,柜内连接,柜顶连接,另设安全网架。用户订货时提供了一次系统图和标准方案,但进出线方式不可能完全表达十分清楚,用户应该现场实际安装要求技术协议中加以说明为妥,到现场安装时发生困难。

There are basically two ways of connection on the switch cabinet: (1) the connection of incoming and outgoing cables and cabinets。 (2) the inlet and outlet lines are drawn from the top wall bushing of the cabinet, and are connected with the busbar bridge, and the busbar bridge is connected with the overhead line through the wall bushing。  There are also a few users。 The cable rack is introduced from the top of the cabinet, the cabinet is connected in the cabinet, the top of the cabinet is connected, and the safety net frame is set up。 A system diagram and a standard solution are provided when ordering, but the way of import and export can not be fully expressed。 Users should be able to explain the actual installation requirements at the scene, and it is difficult to install on site。

6.断路器开断容量正确选择

贵州森时达电力电气有限公司6。 correct selection of interrupting capacity of circuit breaker

贵阳开关柜认为一次系统图上,所选用断路器,表明断路器型号、额定工作电压、额定工作电流外还必须选定断路器开断容量。有用户图纸,断路器开断容量不选定,使制造厂进行工程设计时带来困难,开断容量选择要依据系统短路参数来选定,若制造厂不了解系统短路参数是很难作出正确选择。还有些用户图纸,不考虑系统短路参数情况,盲目选择高开断参数,造成不必要浪费资金。正确选择开断容量是很重要,既要保证安全运行,又要考虑到降低产品成本。贵阳开关柜小编今天就分享到这里了。

Guiyang switchgear thinks that the circuit breaker on the first system diagram indicates that the breaker type, rated working voltage and rated working current must also select the breaking capacity of circuit breaker. There are user drawings and breakers' capacity is not selected, which makes it difficult for manufacturers to carry out engineering design. The selection of breaking capacity should be selected according to the system's short-circuit parameters. If manufacturers don't know the system's short-circuit parameters, it is difficult to make the right choice. There are also some user drawings, which do not consider the system short circuit parameters, blindly select high open and broken parameters, resulting in unnecessary waste of funds. It is important to choose the opening capacity correctly, not only to ensure the safe operation, but also to reduce the cost of the product. The small Guiyang switch cabinet is here today.
