In, if the pole N breaker and firewire breaker structure are completely the same, (BFire+CFire)-(Bn+Cn)=0, S > (Pi-1)A。
In the specific implementation process, the pole the N circuit breaker tripping joining beam 7 of the pole N breaker 1 itself extends to adjacent fire
Behind 2 inside of line breaker, when the contact of firewire breaker 2 disengages, until the moving contact of the firewire breaker 2 moves knot
When structure 18 is moved to close to farthest point, the pole N circuit breaker tripping joining beam 7 is just touched, the contact for causing the pole N breaker 1 is threaded off separation,
At this point, firewire breaker 2 has been in off-position, then the dynamic/static contact that will not cause the pole N breaker 1 generates electric arc；In the pole N
One fan groove 20 is set inside contact mechanism of circuit breaker driving wheel 10, and firewire circuit breaker handle driving wheel 15 is by an one end
The handle shaft coupling driving lever 16 of non-circular structure is together in series, it is ensured that adjacent firewire breakers 2 at different levels link together, and handle shaft coupling is dialled
16 other end of bar is circular shaft structure, and a shifting block 21 is arranged on circular shaft face, and the N that circular shaft end is placed in the pole N breaker 1 is extremely breaking
In device contact mechanism driving wheel 10, shifting block 21 is placed in the fan groove 20 inside the pole N contact mechanism of circuit breaker driving wheel 10, the pole N
Breaker 1 is synchronous with firewire breaker 2 when closing a floodgate, and when combined floodgate, the feed motion of the pole N contact mechanism of circuit breaker driving wheel 10 is
It is stirred by the rotation direction clockwise of shifting block 21 on handle shaft coupling driving lever 16, drives U type connecting rod 9 and the pole N moving contact movement mechanism
12 with firewire breaker 2 synchronize rotate clockwise arrival closing position, fan groove 20 is deducting space in slot shared by shifting block 21
Except fan angle be that shifting block 21 can do the angle rotated freely in fan slot 20, and adjacent firewire circuit breaker handle drives
The combined floodgate of driving wheel 15 is less than shifting block 21 with angle range of operating a switch and does the angle rotated freely in fan slot 20, ensures that phase
Shifting block 21 when adjacent 15 breaking of firewire circuit breaker handle driving wheel does rotation counterclockwise on handle shaft coupling driving lever 16 is in fan groove 20
It inside rotates freely and is not interfered, to would not also cause the breaking synchronous with firewire breaker of the pole N breaker 1, obtain significant N
Disconnected effect after pole breaker 1.
The pole N provided by the invention without arc-control device breaker, first, using the pole N circuit breaker tripping joining beam and firewire
Circuit breaker tripping joining beam, which is formed, intersects mutual inserting structure, constitutes the design of mutually triggering tripping, and the moving contact of firewire breaker is detached from
After contact, and fire the pole N circuit breaker tripping connection again when firewire moving contact of breaker movement mechanism, which moves to, to reach home
Bar movement, the disconnection that ensure that the pole N contact of breaker and the disconnection of adjacent firewire contact of breaker generate the apparent time difference,
To achieve the purpose that the pole N breaker does not generate electric arc；Second, firewire is greater than by the pole N circuit breaker tripping arm spring torsion
The setting of circuit breaker tripping arm spring torsion allows adjacent firewire circuit breaker tripping sensitivity much higher than the pole N breaker, works as chance
When to sharp pounding, firewire breaker can be prior to the pole N circuit breaker tripping breaking, so that the shock resistance of the pole N breaker is far high
In firewire breaker；Fan slot is arranged in third, the pole N contact mechanism of circuit breaker driving wheel inside, and setting is dialled on handle shaft coupling driving lever
Block, shifting block only has in the fan slot certain is freely rotated angular region, it is ensured that powers off after the breaker of the pole N, overcomes biography
System multipole circuit breaker handle is connected in parallel, the disadvantage of the pole N breaker synchronous power-off with firewire breaker；4th, firewire open circuit
Stored energy mechanism is added inside device, and the pole N breaker is not provided with stored energy mechanism, when needing closing of power circuit breaker power supply to do feed motion
When, firewire moving contact of breaker movement mechanism is blocked by stored energy mechanism, and the pole N moving contact of breaker is not stopped,
So achieving the purpose that the pole N breaker first leads to prior to firewire closing of power circuit breaker power supply, the standard of the pole N breaker make-before-break is improved
True property, it is at low cost, it is versatile；5th, it is moved by formula specification N pole circuit breaker tripping joining beam and firewire moving contact of breaker
The distance between mechanism S can adjust distance S according to the quantity of firewire breaker, it is ensured that the pole N breaker and multiple firewires
The accuracy and safety to link between breaker.
