Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof elevators, in particular to a safe explosion-proof elevator. Background Art

[0002] The principle of explosion-proof elevators is the same as that of general elevators, except that explosion-proof elevators must have explosion-proof performance in addition to the necessary performance of general elevators. Intrinsically safe products are energy-safe explosion-proof products, which are often suitable for explosion-proof of weak current systems. Any sparks or thermal effects generated by their circuits under normal working and specified fault conditions cannot ignite the specified explosive gas environment. The combination of explosion-proof technology and intrinsic safety technology in the same product is a community with complementary advantages of two explosion-proof forms. The use of explosion-proof and intrinsically safe composite explosion-proof elevators has stronger operability on site, flexible use, easy maintenance and low cost.
