The support of power;Boss 637 is set on contact base 63, and the effect of boss 637 is to allow the fulcrum top pressure of trip link 10, for the company of dropout
10 accumulation of energy of bar provides support.
When occurring overloading or during short trouble, and when fault current reaches this breaker overcurrent action setting valve, this is disconnected
The L poles breaker 1 that is spaced apart of road device trips, and by mechanism STATEMENT OF FEDERALLY SPONSORED 101, drives electricity behaviour's N pole breakers and trips therewith, at this time such as
Breaker closing is needed, then answers Manual operation handle operating parts 3 to close a floodgate.
Breaker has " automatic/hand " holding function, when toggle switch is placed at " automatic " indicating positions, this breaker
Remote auto " conjunction/separating brake ", after electric energy meter arrearage, electricity behaviour N poles breaker 2 trips after receiving separating brake instruction, is joined by mechanism
Moving part 101, drive are spaced apart L poles breaker 1 and trip therewith, at this time, the switching-on mechanism self-locking inside electricity behaviour N poles breaker 2, i.e., and
Make Manual operation handle operating parts 3, after this breaker closing, electric energy meter can not being made to continue to pay dues, electricity behaviour N poles breaker receives combined floodgate
Automatic closing after instruction, by mechanism STATEMENT OF FEDERALLY SPONSORED 101 and handle operating parts 3, drive is spaced apart L and breaker and closes a floodgate therewith.
The process of electricity behaviour N poles breaker automatic closing:After electricity behaviour N poles breaker receives the instruction of combined floodgate, motor 14 works,
Drive worm screw 13 to rotate, engaged by gear, rotate counterclockwise master gear 8, then drive handle gear 7 to rotate, U-shaped bolt 11 is logical
Cross tripping 9 and promote lock 64, the contact base 63 in actuating mechanism 6 is rotated with axis 61, until moving contact 63 and zero phase stationary contact
First 17 contact, meanwhile, by mechanism STATEMENT OF FEDERALLY SPONSORED 101 and handle operating parts 3, drive is spaced apart L poles breaker and closes a floodgate therewith.
The process of electricity behaviour N poles breaker automatic brake separating:Motor 14 works, and drives worm screw 13 to rotate, is engaged, made by gear
Master gear 8 rotates clockwise, then drives handle gear 7 to rotate, trip link 10 by master gear 8 extruding and top pressure lock 64,
Lock 64 is set to thread off with tripping 9, actuating mechanism 6 resets under the action of mechanism tension spring 12, until moving contact 63 and zero phase stationary contact
First 17 separation, meanwhile, by mechanism STATEMENT OF FEDERALLY SPONSORED 101 and handle operating parts 3, drive is spaced apart L poles breaker and therewith separating brake.
