A kind of pre paid functionality chopper
Technical field
The present invention relates to breaker technical field, particularly to the chopper of a kind of band pre paid functionality.
Background technology
The chopper of existing band pre paid functionality can not carry out disconnection and the connection of power supply automatically, and usage safety performance is low, user connect in-convenience in use.
Summary of the invention
It is an object of the present invention to provide a kind of pre paid functionality chopper, to overcome drawbacks described above.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is: a kind of pre paid functionality chopper, including breaker unit, it is characterized in that: also include that the pre-payment trip unit closed first and then disconnect, described pre-payment trip unit are connected with breaker unit by the conducting rod of Z-shaped bending.
It is right-angle bending rectilinear right-angle folding bent-up end that described conducting rod is connected end with breaker unit, it is inserted between the moving contact of breaker unit, static contact by position to take power, conducting rod L pole, it is in dome-shaped boss that described conducting rod is connected end with pre-payment trip unit, inserts copper pipe by conducting rod N pole for electric position and is connected on electronic controller.
Also include N pole arc quenching system, described N pole 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, and N pole base gathering sill is arranged below isolating and protecting groove.
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, the invention have the benefit that
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 when closing a 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, chopper of the present invention is in open position, when there being control signal to input, the load end induced voltage limit value of chopper is almost nil, electronic control system uses two-way surge suppression technique, ensure the Surge handling capability of pre-power end and signal end, control signal port contact is set flexibly at product input or outfan, meets different customer demands, facilitate user to connect use.

Detailed description of the invention
In conjunction with Fig. 1-Fig. 5, embodiment theory structure schematic diagram for the present invention a kind of pre paid functionality chopper, including breaker unit 1, also include that the pre-payment trip unit 2 closed first and then disconnect, described pre-payment trip unit 2 are connected with breaker unit 1 by the conducting rod 3 of Z-shaped bending;It is right-angle bending rectilinear right-angle folding bent-up end 32 that described conducting rod 3 is connected end with breaker unit 1, it is inserted between the moving contact 9 of breaker unit 1, static contact 10 by position to take power, conducting rod L pole 8, it is in dome-shaped boss 31 that described conducting rod 3 is connected end with pre-payment trip unit 2, inserts copper pipe 13 by conducting rod N pole for electric position 11 and is connected on electronic controller 12;Also include 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, and N pole base gathering sill 4 is arranged below isolating and protecting groove 41;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 a plurality of gathering sill subdividing the arc, and pedestal is staggered with lid gathering sill corresponding, improves voltage between arc and effectively splits extinguishing electric arc, electronic control system is carried out isolating and protecting design, it is to avoid the electric arc ablation to electronic control circuit simultaneously;And its power supply line designed groove on housing protect, it is to avoid arc erosion and cause short circuit.
Breaker unit 1 connects by conducting rod 3 pre-payment trip unit 2 is assembled, right-angle folding bent-up end 32 is position to take power 8 between L pole moving contact 9 and static 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, chopper can close a floodgate, moving contact 9 moves and contacts to static 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 in the copper pipe 13 on electronic controller 12 by dome-shaped boss 31 end of conducting rod 3 supplies electric position 11, and circuit ON normally works;When pre-paying kilowatt-hour meter control signal disappears, by electronic controller 12 calculation process, sending instruction and make pre-payment trip unit 2 thread off, move circuit breaker tripping by linkage, circuit disconnects;Producing electric arc in breaking course and carry out striking segmentation by N pole base gathering sill 4 and N polar cap gathering sill 7, after arc voltage raises, cooling is extinguished.Control signal wire and power line protected by the separation of isolating and protecting groove 41, it is to avoid punctures or short circuit phenomenon because arc erosion causes.
Although the present invention describes according to above-mentioned detailed description of the invention, but the invention thought of the present invention is not limited to that invention, the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
