The work of electric energy meter of the present invention external chopper is as follows:
1, ammeter provides switching signal, and motor-operating mechanism 100 drives chopper A to close a floodgate;
2, after chopper A closes a floodgate, motor 1 inverts, and returns to initial position;
3, now user is in non-arrearage state, can free on/off switch;
4, subscriber arrearage, ammeter provides sub-gate signal, and motor-operating mechanism 100 promotes trip link (push rod 5) separating brake;
5, subscriber arrearage, closing by hand, chopper can not close.
Electric energy meter of the present invention external electric operating mechanism of circuit-breaker technical scheme:
1, direct current generator 1 is fixing with worm screw is connected, and worm screw drives one-stage gear 21 to rotate;
2, having upper and lower two-layer gear on one-stage gear 21, one-stage gear drives secondary gear to rotate;
3, also having upper and lower two-layer gear on secondary gear 22, secondary gear drives the i.e. handsetting gear of tertiary gear to rotate;
4, tertiary gear i.e. handsetting gear 3 positive and negative (the positive back side) projection of having nothing in common with each other, front projection is provided with two and touches with rotating shaft
The raised points hit, two raised points can be to connect, it is also possible to is unconnected, the back side arrange a raised points, one tiltedly
Face is protruding, a magnet steel installing hole;
5, two driving levers 41,42 are set in rotating shaft 4;
6, in making process, a raised points (the first protuberance) of tertiary gear (handsetting gear 3) upper surface (front) promotes
The upper driving lever of rotating shaft rotates, thus drives rotating shaft 4 to move, and and then, (second is convex for another raised points of tertiary gear upper surface
Portion) promote the upper driving lever of rotating shaft to rotate, now owing to two raised points radius of gyration on tertiary gear is different, (radius adds
Long), the radius of gyration the most different (radius shortens) in contact rotating shaft, the radius change superposition on gear 3 and in rotating shaft 4, turn
Speed on axle is undergone mutation (increasing), drives chopper rapid closing (the contact quick-make of chopper sound), improves product
Electrical endurance;After the sound closing of contact, the raised points (the 3rd protuberance) of tertiary gear lower surface (back side) promotes under rotating shaft
Driving lever rotates, and now the raised points of tertiary gear lower surface and the radius of gyration of lower driving lever produce again change, the speed in rotating shaft
Again undergoing mutation (reduction), now breaker closing power is maximum, can reduce the impact to motor after deceleration;
7, in this making process, twice speed change of motor-operating mechanism coordinates the stressing conditions during breaker closing to realize
Flexible Control and rapid closing function, by the closing speed curve after emulation as shown in Figure 7;
8, after breaker closing, motor reversal, return to initial position, drive tertiary gear to separate with between rotating shaft, it is ensured that after combined floodgate,
Chopper can manual divide-shut brake;
9, after receiving sub-gate signal, motor continues reversion, drives tertiary gear, and the ramp projections of tertiary gear pushes away
Bar, push rod promotes circuit breaker tripping parts to thread off, it is achieved breaker open operation.Motor reversal stops after certain position, it is ensured that
Under sub-gate signal after separating brake chopper can not manual divide-shut brake, now ramp projections is positioned at the backstop position of push rod, though user
Closing by hand, chopper can not close, and this state is subscriber arrearage state.
Chopper of the present invention meets " GB10963.1 domestic and similar site's circuit-breakers for over-current protection " standard, meets state
Family's electrical network and south electric network " electric energy meter external Circuit breaker technology specification ", meet China CQC quality certification center CQC1121-
2016 " electric energy meter external Circuit breaker technology specifications ".
