Further, open ice and between pawl 7 and conductive arm 12, be provided with sports limiting device, to ensure pawl 7 to be opened ice in conduction
The slip on arm moving contact surface moves linearly.
Using the structure of the present invention, when disconnecting switch is in full open mode, moving contact of the pawl that opens ice in conductive arm
Region, i.e., foremost；When disconnecting switch is in closing course, in the presence of operation insulator, the pawl that opens ice is moved rearwards by,
Moving contact is destroyed with static contact binding site ice.
When moving contact is combined with static contact, due to the already out contact area of the pawl that opens ice, which is not affected to combine, when keeping apart
When pass closes completely, the pawl that opens ice is in right limit position.
The characteristics of present invention utilizes the shear strength of ice relatively low, drives ice-breaking mechanism simultaneously in the motion of moving contact pull bar
Motion, realizes opening ice for moving contact in closing course, then the moving contact without ice under the work of operating mechanism again to static contact
Open ice.The icebreaking device opens ice for mechanical type, simple and reasonable, reliable operation, disclosure satisfy that the requirement quickly opened ice.
