The fire-resistant enclosed busbar is a busbar system consisting of metal plates (steel plates or aluminum plates) with high fire resistance, which is composed of protective shell, conductive row, insulating materials and related accessories.

耐火母线槽与普通母线槽一样，防护等级越高，防护效果就越好，如果是短时间少量的水分滴落到母线槽外壳上是没有问题的，如果把耐火母线槽直接在水里浸泡，密集型防护等级在IP54以上的还好点，空气型的肯定不行。

Refractory bus slot with common busbar protection, the higher the level, the protective effect is better, if it is a short time a small amount of water onto the casing is no problem, if the refractory bus slot directly soaking in the water, intensive protection grade is better than IP54 in the air, certainly not.

1、必须验证母线槽干线相序正确，母线槽绝缘电阻不低于20MΩ

1. It is necessary to verify that the phase sequence of the main line of the busbar is correct, and the insulation resistance of the busbar slot is not less than 20M Omega.

2、保证母线槽干线不受液体、固体的侵入

2. Ensure that the main line of the busbar is not intruded by liquid and solid.

3、必须确认安装支架稳固，连接螺栓可靠的连接

3. It is necessary to confirm the stability of the mounting bracket and the reliable connection of the connecting bolt

4、接触带电设备的零部件有危险!

4. It is dangerous to contact the parts of the electrified equipment.

5、母线槽开始送电时，不得带负载

5. When the bus slot begins to send electricity, no load is carried.

6、检查总的负载电流不超过主母线电流或设计电流

6, check the total load current does not exceed the bus current or current design
