Embodiment
Composition graphs 1-Fig. 5, for the embodiment theory structure schematic diagram of a kind of pre paid functionality circuit breaker of the utility model, comprise breaker unit 1, also comprise the pre-payment trip unit 2 closed first and then disconnect, described pre-payment trip unit 2 is connected with breaker unit 1 by the conducting rod 3 of Z-shaped bending; Described conducting rod 3 is the rectilinear right-angle folding bent-up end 32 of right-angle bending with breaker unit 1 link, be inserted between the moving contact 9 of breaker unit 1, fixed contact 10 by position to take power, conducting rod L pole 8, described conducting rod 3 and pre-payment trip unit 2 link, for being dome-shaped boss 31, inserting copper pipe 13 by conducting rod N pole for electric position 11 and are connected on electronic controller 12; Also comprise N pole arc quenching system, described N pole arc quenching system is provided with some gathering sill subdividing the arcs, and wherein, breaker unit 1 is provided with N polar cap gathering sill 7, pre-payment trip unit 2 is provided with N pole base gathering sill 4, N pole base gathering sill 4 and is provided with isolating and protecting groove 41 below; N pole base gathering sill 4 on described pre-payment trip unit 2, both sides are provided with control signal end of incoming cables 5 and control signal leading-out terminal 6.
Described pre-payment trip unit 2 includes driving link, conducting system, tripping mechanism, pre-payment tripping system, N pole arc quenching system etc.; Described N pole arc quenching system arranges many gathering sill subdividing the arcs, and pedestal is staggered corresponding with lid gathering sill, improves voltage between arc and effectively splits extinguish arcs, carry out isolating and protecting design simultaneously, avoid electric arc to the ablation of electronic control circuit to electronic control system; And on housing, groove protection is designed to its power supply line, avoid arc erosion and cause short circuit.
Breaker unit 1 is by the assembled connection of conducting rod 3 pre-payment trip unit 2, right-angle folding bent-up end 32 is position to take power 8 between L pole moving contact 9 and fixed contact 10, when pre-paying kilowatt-hour meter control signal is accessed by control signal end of incoming cables 5 or control signal leading-out terminal 6, circuit breaker can close a floodgate, moving contact 9 moves to and contacts with fixed contact 10, moving contact 9 contacts with the right-angle folding bent-up end 32 of conducting rod 3 simultaneously, the N pole that main circuit power is connected to by dome-shaped boss 31 end of conducting rod 3 in the copper pipe 13 on electronic controller 12 supplies electric position 11, and circuit ON normally works; When pre-paying kilowatt-hour meter control signal disappears, by electronic controller 12 calculation process, send instruction and pre-payment trip unit 2 is threaded off, move circuit breaker tripping by linkage, circuit disconnects; Produce electric arc in breaking course and carry out striking segmentation by N pole base gathering sill 4 and N polar cap gathering sill 7, arc voltage cools extinguishing after raising.Control signal wire and power line are protected by the separation of isolating and protecting groove 41, avoid and puncture or short circuit phenomenon because arc erosion causes.
