How to choose ballast for explosion proof lamp?
However, the internal temperature of the isolation cover is poor, so the environmental temperature index of the ballast is required. It is better to work at 50 or above.The so-called isolated explosion refers to the presence of flammable gas inside and outside the isolation hood, the internal deflagration, short circuit, arc and other accidents, the energy generated in the discharge process will not ignite the external combustible gas.
Regular ballast products are marked with the highest operating temperature (Tw), at 90~130 degrees, depending on the need to choose, the more compact space, the higher the required temperature.The temperature, performance, and stability of an electronic rectifier are poor, it is recommended that the wire wound.Other depends on whether the installation is convenient.
The explosion proof lamp is usually isolated and explosion-proof. If the ballast is installed inside the isolation cover, there is no particular requirement for the ballast in theory.
