Explosion-proof switch, as the name suggests, is able to be used in the harsh and dangerous explosion environment. Examples include the coal mining industry, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewerage. Need to use explosion-proof switch. At present, the explosion-proof switch on the market a lot of brands and types, but in the real sense, with excellent explosion-proof performance, safe and reliable quality explosion-proof switch, the market is still relatively small. Among them, the British Bulgin brand is ideal. Bulgin's explosion-proof switch, based on the design of dangerous explosion-proof professional environment, in line with ROHS certification, through specialized testing, suitable for a variety of harsh environments. Factory explosion-proof electrical explosion-proof control switch which Such products market demand is also relatively large, so there are more manufacturers, including lighting switches, switches (combination switch), limit switches, cable switches and other small explosion-proof products. Explosion-proof grade of these products up to â…¡ CT6 level, the shell of the explosion-proof shell is usually made of cast aluminum alloy die-casting composite structure, there are a few manufacturers use other materials shell. Such products are characterized by small size, internal components of a single - low technical content, simple structure, easy to make. Explosion-proof electrical equipment switch and controller of the special technical requirements DC contact switch, not allowed to make oil immersion structure. Class I exchange contact switch, only when the rated voltage is higher than 1140V, the poles isolated from each other and contains no more than 5L per pole oil was allowed to make the oil immersion structure. Class â… electromagnetic switch isolating switch, breaking capacity below JK3 load, to be electrically or mechanically interlocked with the contactor; â…¡ may also set a warning plate instead. Class â… switch, if there is no short circuit, leakage protection, the protection device action mechanism must be manually reset the form. The resetting device must have special fasteners or may be located inside a protective enclosure. If the controller handle is detachable, be sure to remove it when it is in the stop position. Class â… oil circuit breaker breaking capacity, should be the actual maximum breaking capacity of 50%.
