开关柜柜体配电装置设置有哪些要求

What are the requirements for the switchgear distribution device setting

贵州开关柜厂

贵州开关柜厂听说正常情况下,开关柜柜体的装置与外部电缆的连接是在带电缆隔室中完成的,这样电缆就可以上下进出;而且当零序电流互感器置于电缆隔室内的时候,对其安装维修也能更加方便。

Guiyang switchgear that under normal circumstances, connecting device of switch cabinet body and the external cable is completed in cable compartment, this cable can up and down and out; and when the zero sequence current transformer in the cable compartment, can be more convenient for the installation and maintenance.



在开关柜中,如果是同一电源配电系统的话可以通过限流电抗器匹配限制短路电流,稳定母线电压在一定的数值;还可部分降低对元器件短路强度的要求,使得开关柜处理稳定的状态下工作。

In the switch cabinet, if it is the same power distribution system, you can limit the short-circuit current through the current limiting reactor, bus voltage stability in a certain value; also could reduce the components of short circuit strength requirements, making the switch cabinet stability condition.




作为开关柜的配电装置,它的抽屉单元应有足够数量的二次插插件,这样才能满足计算机接口和自控回路对接点数量的要球;并且尽可能的提高转接件的热容量,有助于较大幅度的降低由于转接件的温升给接插件、电缆头、间隔板带来的附加温升。

As a power distribution device for switch cabinet, two plug-in the drawer unit should have an adequate number, so as to satisfy the computer interface and control circuit of the contact number of the ball; and as far as possible to improve the heat capacity of the adapter, helps to reduce greatly due to the temperature rise to the attached adapter connector, temperature cable head, bring up the partition.




在开关柜柜体配电装置内部,功能单元之间、隔室之间的分隔必须清晰、可靠,不因某一单元的故障而影响其他单元工作,使故障局限在最小范围;要求采用母线平置式排列,使装置的动、热稳定性好,能承受一定短路电流的冲击。贵阳开关柜小编分享到这里了。

In the internal switch cabinet power distribution device, function unit, isolation between compartments between must be clear and reliable, not because of the failure of one unit and affect the work of other units, the fault limits in the minimum range; require the use of flat type busbar arrangement, the device of the dynamic and thermal stability, can withstand short circuit current impact. Guiyang switch cabinet small editor to share here.
