Summary of the invention
The object of the invention is, a kind of pre paid functionality circuit breaker is provided, to overcome above-mentioned defect.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of pre paid functionality circuit breaker, comprise breaker unit, it is characterized in that: also comprise the pre-payment trip unit closing first and then disconnect, described pre-payment trip unit is connected with breaker unit by the conducting rod of Z-shaped bending.
Described conducting rod and breaker unit link are the rectilinear right-angle folding bent-up end of right-angle bending, be inserted in by conducting rod L utmost point position to take power between the moving contact, fixed contact of breaker unit, described conducting rod and pre-payment trip unit link, for being dome-shaped boss, insert copper pipe by the conducting rod N utmost point for electric position and are connected on electronic controller.
Also comprise N utmost point arc quenching system, described N utmost point arc quenching system is provided with some gathering sill subdividing the arcs, and wherein, breaker unit is provided with N polar cap gathering sill, pre-payment trip unit is provided with N pole base gathering sill, is provided with isolating and protecting groove below N pole base gathering sill.
N pole base gathering sill on described pre-payment trip unit, both sides are provided with control signal end of incoming cables and control signal leading-out terminal.
Compared with prior art, beneficial effect of the present invention is:
1, the linear end of conducting rod of the present invention inserts between the dynamic and static contact of breaker portion, and product carries out power supply power taking automatically while combined floodgate, and dome-shaped end inserts copper pipe and is connected on electronic controller, and dome-shaped design increases the reliability being connected with copper pipe;
2, circuit breaker of the present invention is in open position, in the time having control signal input, the load end induced voltage limit value of circuit breaker is almost nil, electronic control system adopts two-way surge suppression technique, ensure the antisurge ability of pre-power end and signal end, control signal port contact is set flexibly at product input or output, meets different customer demands, facilitate user to connect use.

Embodiment
In conjunction with Fig. 1-Fig. 5, for the embodiment theory structure schematic diagram of a kind of pre paid functionality circuit breaker of the present invention, comprise breaker unit 1, also comprise the pre-payment trip unit 2 closing 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 in by conducting rod L utmost point position to take power 8 between the moving contact 9, fixed contact 10 of breaker unit 1, described conducting rod 3, inserts copper pipe 13 by the conducting rod N utmost point for electric position 11 and is connected on electronic controller 12 for being dome-shaped boss 31 with pre-payment trip unit 2 links; Also comprise N utmost point arc quenching system, described N utmost point 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, and N pole base gathering sill 4 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 utmost point arc quenching system etc.; Described N utmost point 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 cuts apart extinguish arcs, electronic control system is carried out to isolating and protecting design simultaneously, avoids the ablation of electric arc to electronic control circuit; And its power supply line is designed to groove protection on housing, 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 utmost point moving contact 9 and fixed contact 10, in the time that pre-paying kilowatt-hour meter control signal accesses 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 fixed contact 10 and contacts, moving contact 9 contacts with the right-angle folding bent-up end 32 of conducting rod 3 simultaneously, the N utmost point that main circuit power is connected in the copper pipe 13 on electronic controller 12 by dome-shaped boss 31 ends of conducting rod 3 supplies electric position 11, and circuit is connected normal work; In the time that pre-paying kilowatt-hour meter control signal disappears, by electronic controller 12 calculation process, send instruction pre-payment trip unit 2 is threaded off, move circuit breaker tripping by linkage, circuit disconnects; In breaking course, produce electric arc and carry out striking by N pole base gathering sill 4 and N polar cap gathering sill 7 and cut apart, cooling extinguishing after arc voltage raises.Control signal wire and power line, by the separation protection of isolating and protecting groove 41, have been avoided puncturing or short circuit phenomenon because arc erosion causes.
Although the present invention describes according to above-mentioned embodiment, invention thought of the present invention is not limited in this invention, and the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
