建筑电气开关防水问题及技术对策

Waterproof Problems and Technical Countermeasures in Building Electrical Switches

建筑电气开关进水的途径有通过法兰间隙进水、孔距加工存在误差等,尽管很多施工单位重视开关防水工作,但仍然存在不足,主要表现为开关防水不彻底、不利于开关维修、堵塞泄压通道等。为转变这种情况,提高建筑电气开关防水性能,施工中应采取有效技术对策,提高电气开关施工质量、采取电气开关防水措施、改进开关防水等级标准、适当增加系统冗余量,并合理选择电气开关元件。

Through the flange gap inlet, the pitch of holes machining error for building electrical switch water way, although many construction unit attached to a switch waterproof work, but there are still shortcomings, mainly as a waterproof switch is not complete, is not conducive to the maintenance switch, plug the pressure relief passage.To change this kind of situation, improve the building electrical switch waterproof performance, the construction should take effective technical measures, improve the construction quality of electrical switch, adopting the electric switch waterproof measures, improve the switch waterproof grade standard, appropriate to increase the redundancy of the system, and a reasonable choice of electrical switching element.
