DGC18/127L (A) mine mine explosion Fixture Tips: 1, explosion-proof electrical equipment seals what role? Explosion-proof electrical equipment is to ensure that the introduction of cable terminal box seals proof performance of a measure. Therefore requires proof procedure for seals made specific provisions. 2, why should require clearances and creepage distances? Different potentials bare minimum air distance between conductors called clearance. Bare conductors with different potentials separated solid insulation, starting from a conductor along the solid insulated conductor surface to another is called the length of the shortest path creepage distance (Calculation example see GB3836.3-2000 4.3, 4.4 bar). Clearances and creepage distances are two different concepts, but both different but linked, the former with pure air dielectric strength (or breakdown voltage) are closely related, and the latter with the surface of the solid insulation breakdown voltage (or known as surface discharge voltage, the surface flashover voltage) are closely related. Distributed in the same field, the electrical clearance and creepage distance is equivalent to two "parallel" breakdown channels. Experimental results show that the surface discharge voltage is significantly lower than the breakdown voltage of pure electrical clearance, which is the same voltage level, why creepage distances tend to be larger than the clearance value causes. In order to ensure the safe use of electrical equipment, for different voltage levels and different insulation materials should be separately specified clearances and creepage distance value. Explosion-proof electrical equipment inside the terminal box (increased safety to be included inside the body) Clearances, creepage distance requirements than the general electrical equipment requirements. Explosion-proof electrical equipment inside the body, such as electrical clearances, creepage distances apply general-voltage equipment requirements.
