Most of the bus duct is the design standard for indoor use, so even if the humidity in the indoor air is relatively high, it will not have much impact on the operation of the busbar, but the bus duct enters the water during the use process, which will definitely cause a certain degree of impact, if it runs for a long time in this water situation, I am afraid that it will constitute a short circuit and then burn the busbar. Therefore, regarding the situation that may constitute the water ingress of the busway, the equipment needs to understand some precautions at the beginning to avoid such incidents.
Proper protection. For example, when the laying demand of the bus duct passes through the construction floor, due to various reasons such as production or roof leakage, it may constitute water accumulation on the floor, and it will leak down the bus duct through the floor, constituting water ingress into the bus, so that the bus insulation is reduced.
Outdoor waterproofing method:
If the busway equipment is located outdoors, it is necessary to carefully consider the waterproofing method. Water ingress in the operation, will inevitably lead to the decline of insulation function, long-term operation will constitute a short circuit and then incinerate the bus to cause severe electrical incidents, in this situation to choose the protection method.
There are two methods that are generally used:
The best way is to choose a new waterproof busway (also known as pouring busway), the product uses high-performance insulating resin, the busbar is directly poured and sealed, the protection level reaches IP68, with waterproof, fireproof, anti-corrosion, explosion-proof and other four-proof functions of the new metal-free shell busway, which is mainly suitable for a variety of harsh and highly polluted environments.
Another method is to add some waterproof eaves outside the outdoor bus duct and install a rain cover to prevent the entry of rainwater, but this method can only play a brief waterproof effect, and cannot deal with a variety of outdoor equipment problems at one time like pouring bus duct.
