Therefore, develop, develop and produce a kind of rational in infrastructure, compact, volume is little, low-cost, the disc type vacuum interrupter that can cut-off high voltage more, have the double function, 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, a kind of novel disc type double vacuum interrupter is provided, this disc type double vacuum interrupter adopts the New Rotary moving contact structure, 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: this disc type double vacuum interrupter, comprise the disc type insulation crust, vacuum interrupter and be arranged on the fixed contact and the moving contact of vacuum extinction chamber interior, be characterized in the disc type vacuum interrupter of described vacuum interrupter for linking to each other with the insulation axle, this disc type vacuum extinction chamber interior is provided with 2 pairs of fixed contacts and 2 pairs of moving contacts, 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 disc type vacuum interrupter and is connected with conductor bull stick mid portion, fixed contact is fixed on the fixed contact pedestal with disc type insulation crust one, be separately installed with moving contact on the end face at conductor bull stick two ends, the conductor bull stick drives moving contact and is just doing under the driving of insulation axle revolving force, any a pair of fixed contact is connected in despining, to realize the function of double.
For better realizing the purpose of this utility model, described disc type vacuum interrupter conductor inside bull stick main body is a linear pattern, two ends are camber line shape, entire length is less than the diameter of disc type vacuum interrupter disk, 2 pairs of moving contacts are installed in respectively on the end face at conductor bull stick two ends, the conductor bull stick drives moving contact and does positive and negative rotation under the driving of an insulation revolving force, can make dynamic and static contact realize effectively contact or separation when the conductor bull stick rotates.
For better realizing the purpose of this utility model, every pair of fixed contact (is that fixed contact a and fixed contact b are a pair of, fixed contact c and fixed contact d for another to) be symmetric position in the vacuum extinction chamber interior, guaranteed the synchronism that moving contact and 2 fixed contacts contact, separate.
For better realizing the purpose of this utility model, (fixed contact a and fixed contact b are a pair of to described 2 pairs of fixed contacts, fixed contact c and fixed contact d for another to) insert respectively in 2 tunnel loops, drive conductor bull stick, moving contact rotation by the insulation axle, effectively connect any a pair of fixed contact, realized the function of double.
Compared with prior art, the beneficial effects of the utility model are: 1. replaced traditional electromagnetic mechanism with motor or other power source, be convenient to control, save cost.
2. 2 groups of fixed contacts can insert 2 tunnel loops respectively, thereby can optionally connect the function that double has been realized in any loop.
4. along with the raising of electric pressure, diameter that can be by increasing disk and the distance of adjusting dynamic and static contact and insulation axle center improve the disjunction distance and the linear velocity of dynamic and static contact on circumference of dynamic and static contact, thereby have guaranteed to open apart from the requirement of, breaking speed and insulation distance.
5. the arc control device of disc type 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.
