| description | The invention relates to a contact coil for generating an arc extinguishing magnetic field and a vacuum arc extinguishing chamber contact structure. The contact coil comprises a coil main body, the coil main body comprises a conducting rod connecting part, an arc contact piece connecting part and a conductive flexible connection, one end of the conductive flexible connection is fixedly and conductively connected with the conducting rod connecting part, and the other end of theconductive flexible connection is fixedly and conductively connected with the arc contact piece connecting part. The conductive flexible connection has a set deformation amplitude, and when a conductive rod drives a conductive rod connecting end to move towards the direction far away from an arc contact, a set maximumdistance is formed between the conductive rod connecting end and an arc contact piece connecting end. The requirement for the size of a fracture formed after a main contact piece at the end of the conducting rod is separated |
