For the explosion-proof switch , we must have a certain understanding of it, it is not only small, light weight, long life, but also protection, in the circuit overload, leakage can automatically cut off the power to protect everyone's safety, therefore, is Widely used in various dangerous places. Well, explosion-proof switch, which has several do, explosion-proof switch What are the characteristics of it, the following paper to tell you under the bar. What kind of explosion-proof switch 1, inverted switch Reversing switch appearance uses high-strength alloy aluminum one-time die-casting molding, the surface after high-speed shot blasting after high-pressure electrostatic spray processing. The shell structure is compact and reasonable, the material density is high, the strength is high, the explosion-proof performance is excellent, the surface plastic powder has strong adhesion, good anti-corrosion ability, smooth surface, nice appearance, and excellent waterproof and dustproof performance. The machine is equipped with inverted switch, which is mainly used in the electric circuit below 100A, as the power introduction switch, and can control the electric start, stop, commutation and so on. 2, pull switch The pull switch appearance adopts aluminum alloy precision die-casting bright body, high strength, light weight, shell protection grade up to IP67, can work in bad environment for a long time; the machine adopts imported original, large electric shock capacity, sensitive and reliable action. 3, lighting switch Explosion-proof lighting switch structure compact and reasonable, high material density and strength, excellent explosion-proof performance, with excellent waterproof performance. Currently widely used in oil exploration, oil refining, chemical, military and other dangerous environments and offshore oil platforms, tankers and other places. 4, Explosion-proof limit switch Explosion-proof trip switch appearance made of aluminum alloy shell, the surface after the spray treatment, built-in high breaking small circuit breaker, with overload, short circuit protection, and with leakage protection according to the requirements. Explosion-proof stroke mainly through the steel or cable wiring, a left rocker type, right rocker type, roller plunger type, double rocker type, flexible contact type optional, mainly used for temperature group T1-T6 explosive gas In the environment. Explosion-proof switch features 1, the shell is made of ZL102 aluminum alloy die-casting, the surface of high-pressure electrostatic spray, compact structure, beautiful appearance. 2, the product is a composite structure, flameproof enclosure built-in wall switch. 3, steel pipe or cable wiring. 4, the product has waterproof, dustproof and other characteristics. Article Summary: Explosion-proof and explosion-proof switch, which has several switches What are the characteristics of knowledge on the introduction here, I hope to let everyone have some knowledge of explosion-proof switch, explosion-proof switch currently widely used in a variety of dangerous explosive atmospheres, Being able to adapt to various harsh environments is an indispensable tool in the field of petrochemicals.
