And transmission is turned to by wherein steering mechanism, to push the contact end of lower moving contact 4 along predetermined direction counter motion
It closes a floodgate, i.e., is contacted with the pole N static contact 6.To pass through steering mechanism, so that the contact of the contact end of upper moving contact 3 and lower moving contact 4
It holds to different directions and moves, i.e., the contact end of upper moving contact 3 is with the contact end of lower moving contact 4 mutually far from mobile.It needs to illustrate
It is that wherein the effect of rotating mechanism is to turn to, i.e., the driving at the driving end of transmission mechanism is subjected to deflecting transmitting, transfer mode
Generally rotate.A kind of simple structure, wherein steering mechanism can be the pin shaft being rotatablely connected with lower moving contact 4, this is at present
The tail end of moving contact 4 and the driving end of transmission mechanism abut against, to receive the driving force at transmission mechanism driving end, because middle part is logical
Pin shaft rotation connection is crossed, so that the other end of lower moving contact 4, i.e. contact end, move round about.
When closing handle 1, at this time under the action of transmission mechanism, close a floodgate on upper moving contact 3 toward predetermined direction movement, and
Under the action of transmission mechanism, wherein the contact end of one end of steering mechanism and upper moving contact 3 is moved to predetermined direction simultaneously, this
When on moving contact 3 complete to close a floodgate, and under the steering-effecting of steering mechanism, the other end of steering mechanism push lower moving contact 4 to
The reverse movement of predetermined direction, to complete to close a floodgate.In the breaker operator component operating system, wherein upper moving contact 3 is under
Moving contact 4 is moved round about to complete to close a floodgate, and distance farther out, is distributed between closing position with being conducive to heat, right
The magnetic direction for the pole N at this time answered to the pole L play the role of it is advantageous strengthen disjunction when electric arc movement velocity, improve product
Breaking capacity.In conclusion can to efficiently solve calorific value at moving contact big for the operating system of the breaker operator component
And the problem of concentrating and temperature is caused to increase.
Further, steering mechanism herein preferably wherein is the structure being rotatablely connected with breaker operator package base,
