The mode of lower face installation, magnetizing direction is vertical with disjunction plane, and the right opposite polarity of two permanent magnets is consistent, same using magnetism
Property the principle repelled each other so that the two is dividing section part superposition to generate the magnetic-field component for being enough breaking current, and the component magnetic
Field direction is perpendicular to current direction, so that electric arc is mobile towards the direction for being parallel to permanent magnet magnetizing direction, final disjunction
Electric current, and make the disjunction situation of product unrelated with flowing to for electric current, i.e., product has electrodeless sexual function, and entire technical solution is not
Only realize the electrodeless sexual function of product, moreover it is possible to save cost.
Technical solution
In order to achieve the above technical purposes, a kind of D.C. high-current break-up device provided by the utility model, it includes base
Seat, static contact are mounted on the pedestal, and for moving contact on moving contact rack, the moving contact rack is mounted in the pedestal
On, the on-off of the break-up device is realized in the engagement and separation of the moving contact and static contact, and the moving contact and static contact connect
Closing with plane locating when disjunction is disjunction plane, it is characterised in that: permanent magnet mounting bracket is on the pedestal, Yi Duiyong
In the permanent magnet mounting bracket, the pair of permanent magnet is located above and below the disjunction plane magnet,
The opposite one side polarity of the pair of permanent magnet is identical, and the magnetizing direction of the pair of permanent magnet makes perpendicular to the disjunction plane
The useful effect that the pair of permanent magnet provides is oriented parallel to magnetizing direction in the magnetic blow-out power of breaking arc.
Further, the pair of permanent magnet is located above and below the disjunction plane close to the one of static contact
Side.
Preferably, the pair of permanent magnet is located at the side above and below the disjunction plane close to static contact
Face and set.
Further, the permanent magnet mounting bracket includes rack body, and the rack body is on the pedestal, stationary contact
Head is fastened with the rack body, and the pair of permanent magnet respectively corresponds the permanent magnet trough mounted in the rack body
It is interior.
Beneficial effect
A kind of D.C. high-current break-up device provided by the utility model, two pieces of permanent magnets take face installation up and down
Mode, magnetizing direction is vertical with disjunction plane, and the right opposite polarity of two permanent magnets is consistent, utilizes the magnetic original that identical charges repel each other
Reason, so that the two is dividing section part superposition to generate the magnetic-field component for being enough breaking current, and the component magnetic field direction is vertical
In current direction, so that electric arc is mobile towards the direction for being parallel to permanent magnet magnetizing direction, final breaking current, and make
The disjunction situation of product is unrelated with flowing to for electric current, i.e., product has electrodeless sexual function.The program is not only able to achieve nonpolarity function
Can, while installation space and permanent magnet material are saved, under the premise of assurance function, also reduce product cost.
