Zusammenfassung:The utility model discloses a mining explosion-proof and intrinsically safe type six-loop starter having the lighting integrated protection function. The mining explosion-proof and intrinsically safe type six-loop starter comprises an explosion-proof housing. The explosion-proof housing comprises a master control cavity, a door cover and a wire connection box. Three drawer-type modular driving units which can be pushed and pulled in a translation manner, a lighting transformer and a lighting system integrated protection device are arranged in the master control cavity. Each drawer-type modular driving unit comprises two vacuum contactors having a rated current of 40-160A, a protection controller, a RC overvoltage absorbing component, a controlled power transformer, a fuse, an intrinsically safe type pilot loop module, and an intermediate relay. The mining explosion-proof and intrinsically safe type six-loop starter of the utility model has the following advantages that the lighting transformer and the lightin
