MNS低压抽屉柜能靠墙安装吗?

发布时间:2021-01-15 来源:http://www.tongyuhengcheng.com/ 浏览量:

关于低压抽屉柜安装规范,我国是统一规定的。根据变电所低压配电室的配电设备布置,应符合我国标准《10kV及以下变电所设计规范》(GB50053-94)的规定。关于低压抽屉柜能否靠墙安装,里面有明确的规定。敲黑板,划重点,不能!不能!不能!重要的事情说三遍。
The installation specification of low-voltage drawer cabinet is unified by the state. According to the distribution equipment layout of the low-voltage distribution room of the substation, it should comply with the national standard "code for design of 10kV and below substations" (GB 50053-94). There are clear regulations about whether the low-voltage drawer cabinet can be installed against the wall. Knock on the blackboard, draw the point, no! No! No! Important things are to be repeated for 3 times.
虽然,有些低压抽屉柜厂家说明中是可以靠墙安装的,而且一部分低压柜型号的产品,所有接线都是柜前操作,柜后面是封闭的,靠不靠墙似乎没啥影响。但是考虑到巡视、检修、通风散热考虑,开关柜与墙需要保持一定的距离。而且规定就是规定,在规定没有更改之前,任何人不要有侥幸心理。万一出了事故,违规安装的责任谁也承担不起。
Although, some low-voltage drawer cabinet manufacturers can be installed against the wall, and part of the low-voltage cabinet model products, all wiring is in front of the cabinet operation, the back of the cabinet is closed, it seems that there is no influence whether it is against the wall or not. However, considering the inspection, maintenance, ventilation and heat dissipation, the switch cabinet and the wall need to keep a certain distance. And the rule is the rule. Before the rule is changed, no one should take chances. In case of an accident, no one can bear the responsibility of illegal installation.
关于MNS低压抽屉柜的安装规范还有以下规定:
The installation specification of MNS low-voltage drawer cabinet also has the following provisions:
1·配电室的位置应靠近用电负荷中心,设置在尘埃少、腐蚀介质少、干燥和震动轻微的地方,并宜适当留有发展余地。
1. The distribution room should be located close to the power load center, where there is less dust, less corrosive medium, dry and slight vibration, and there should be room for development.

Sealing measures shall be taken around the base to prevent mice, snakes and other small animals from entering the box.
5·同一配电室内并列的两段母线,当任一段母线有一级负荷时,母线分段处应设防火隔断措施。
5. For two sections of bus in parallel in the same distribution room, when any section of bus has first-class load, fire isolation measures shall be set at the section of bus.
6·当高压及低压配电设备设在同一室内时,且二者有一侧柜顶有裸露的母线,二者之间的净距不应小于 2m。
6. When the high-voltage and low-voltage distribution equipment are located in the same room, and there is an exposed bus on one side of the cabinet top, the clear distance between the two should not be less than 2m.
7·成排布置的配电屏,其长度超过 6m 时,屏后的通道应设两个出口,并宜布置在通道的两端,当两出口之间的距离超过15m 时,其间尚应增加出口。
7. When the length of the distribution panel arranged in rows exceeds 6m, the channel behind the panel should be set with two outlets, which should be arranged at both ends of the channel. When the distance between the two outlets exceeds 15m, there should be more outlets between them.
8·成排布置的配电屏,其屏前和屏后的通道最小宽度应符合下表的规定。
8. The minimum width of the channel in front of and behind the distribution panel arranged in rows shall meet the requirements of the following table.
