Above-mentioned auxiliary contact device can be mechanical type or electronic type position detecting switchs such as travel switch, limit switch or sensitive switch.
Further, the auxiliary contact device is arranged on the stationary parts of major loop branch/closing operation mechanism, and the position detection component of auxiliary contact device is arranged in the scope of movable stroke of major loop branch/closing operation motion of mechanism parts.
Further, the auxiliary contact device is arranged on the stationary parts of major loop branch/closing operation mechanism, the position detection component of auxiliary contact device is arranged in the scope of movable stroke of major loop branch/closing operation motion of mechanism parts, when on major loop branch/closing operation motion of mechanism component movement certain position to its activity stroke range, by Mechanical Contact or electronic induction, change the branch of auxiliary contact device contact/close state.
Each of its auxiliary contact device is conventional normally open contact or normally closed interlock to contact.
Particularly, position detecting switch is arranged on the fixed support at moving contact rack rear of major loop branch/closing operation mechanism, and the position detection component of position detecting switch is arranged in the scope of movable stroke of major loop branch/closing operation mechanism moving contact rack.
Compared with the prior art, the utility model has the advantages that:
1. by position detecting switch is set, leakage comprehensive protector has been had and major loop contact terminal branch/close the auxiliary contact of state interlock, can export the contact point signal of true reflection earth leakage protective device operating state;
2. adopt position detecting switch power consumption hardly, reduced the operation energy consumption of protective device, avoided coil heating that external auxiliary relay brings or the drawback of burning, functional reliability is greatly improved;
