Embodiment
Be described further below in conjunction with the enforcement of accompanying drawing to the utility model vacuum switch tube: the spiral winding coil in the utility model is arranged between conducting rod and the contact, baffle is connected with contact coil on electric, the structure on sound both sides is identical, and 180 degree stagger on the direction.
Spiral winding coil in the utility model adopts the oxygen-free copper section bar of square-section, makes crosspiece and conducting rod welding in the middle of it, external end and contact welding with the mode of twining; Baffle is an anaerobic arc piece made of copper, its one side and the terminal welding of spiral winding coil, another side and contact welding; Contact is a round pie, makes with general vacuum switch tube contact material, and its non-arcing face and baffle and contact support welding; It is the round pie structure that contact supports, and with manufacturings such as bigger material of resistivity such as stainless steels, contact supports between welding and spiral winding coil and the contact, and a booster action prevents spiral winding coil stress deformation in use.
Operation principle of the present utility model: in the vacuum switch tube "on" position, dynamic/static contact contacts under mechanism pressure, electric current forms guiding path by moving conductive rod 1 → spiral winding coil 2 → baffle 3 → contact 5 → contact 5 → baffle 3 → coil 2 → static conductive rod 6, and the electric current of vacuum switch is flow through in conducting.When the vacuum switch separating brake, mechanism drives moving conductive rod and moved end electrode, moving contact separates with fixed contact and to from the moving contact distance position for opening distance, between dynamic/static contact, produce the vacuum arc of forming by the metallic vapour of ionization, the path of current that flows through the sound coil is a spirality, the circumferential components of electric current produces magnetic field, because sound end-coil structure is identical, the direction of the circumferential components of electric current is also identical, so the magnetic field that produces is identical at longitudinal direction, the intensity mutual superposition, opposite at horizontal direction, intensity is cancelled out each other, between contact, form like this with regard to strong longitudinal magnetic field, make vacuum arc remain on non-coherent condition, at current zero-crossing point, vacuum arc is extinguished.The key that longitudinal magnetic-field electrode cut-offs success is vacuum arc will be remained on non-coherent condition, and electric current is big more, the numerical value of the K that needs big more (annotating the K=current/magnetic field), and the coil electrode of same diameter can produce stronger magnetic field, just can cut-off bigger electric current.
