Therefore, develop, develop and produce a kind of rational in infrastructure, compact, volume is little, low-cost, can cut-off high voltage more, have the vacuum interrupter of double function and novel rotation structure of contact terminal, be numerous potential user expect needed with market.
Summary of the invention
The purpose of this utility model just is to overcome the defective that existing vacuum arc-extinguishing chamber contact structure exists, the fan-shaped vacuum interrupter of double of a kind of double function, novel rotation structure of contact terminal is provided, the fan-shaped vacuum interrupter of this double adopts the New Rotary structure of contact terminal, rotational power can be provided by motor or other power source, have rational in infrastructure, compact, volume is little, low-cost, can cut-off the more characteristics of voltage levels and double function.
The technical solution that the utility model provides is: the fan-shaped vacuum interrupter of this double, comprise vacuum interrupter and be arranged on the fixed contact and the moving contact of vacuum extinction chamber interior, be characterized in the fan-shaped vacuum interrupter of described vacuum interrupter for linking to each other with the insulation axle, this fan-shaped vacuum extinction chamber interior is provided with 2 fixed contacts and 1 pair of moving contact, described insulation axle one end is connected with power source, the other end then puts in disc type vacuum extinction chamber interior from the circle centre position of fan-shaped vacuum interrupter and links to each other with an end of conductor bull stick, fixed contact is fixed on the fixed contact pedestal with the insulation wall one of fan-shaped vacuum interrupter, the both sides of the other end end face of conductor bull stick are equipped with moving contact, insulation axle drives the rotation of a conductor bull stick, moving contact is effectively contacted with any one fixed contact or separates.
For better realizing the purpose of this utility model, described fan-shaped vacuum interrupter conductor inside bull stick main body is a linear pattern, one end links to each other with the insulation axle by insulating frame, 1 pair of moving contact is equipped with in the both sides of other end end face, and the conductor bull stick can drive moving contact and do the specific positive and negative rotation of angle under the driving of the revolving force of insulation axle; Described fixed contact is installed on the fixed contact pedestal with the insulation wall one, can make near fan-shaped vacuum interrupter circumference dynamic and static contact realize effectively contact or separate when conductor rods rotates.
For better realizing the purpose of this utility model, described 2 fixed contacts are symmetricly set on 2 drift angle places and the fixed contact pedestal insulation wall one of fan-shaped vacuum interrupter.
For better realizing the purpose of this utility model, described 2 fixed contacts insert an end in 2 tunnel loops respectively, moving contact then inserts the common port in 2 tunnel loops, drive conductor bull stick, moving contact rotation by the insulation axle, moving contact and any one fixed contact are effectively connected, thereby optionally connected the function that double has been realized in the loop.
Compared with prior art, the beneficial effects of the utility model are: 1. motor has replaced traditional electromagnetic mechanism, is convenient to control, saves cost.
2. 2 groups of fixed contacts can insert 2 tunnel loops respectively, and moving contact then inserts the common port in 2 tunnel loops, can optionally connect any loop, thereby have realized the function of double.
3. owing to adopt the structure of contact terminal of rotation type, along with the linear velocity of the increase contact of fan-shaped vacuum extinction chamber size with open apart from also increase thereupon, can improve the capacity that cut-offs of vacuum circuit-breaker under the situation that does not influence the speed of cut-offfing, breaking through existing electric pressure for vacuum circuit-breaker provides possibility.
4. fan-shaped vacuum interrupter can reduce the cumulative volume of circuit breaker, and the maintenance, repair of being more convenient for, and the arc control device internal structure is simple, compact, has improved reliability of products.
