Abstract
A disc-type double-station vacuum arc extinguish chamber comprises a disc-type insulated shell, a vacuum arc extinguish chamber, fixed contacts and moving contacts, wherein the fixed contacts and the moving contacts are disposed in the vacuum arc extinguish chamber. The disc-type double-station vacuum arc extinguish chamber is characterized in that the vacuum arc extinguish chamber is a disc-type vacuum arc extinguish chamber connected with an insulated shaft. Two pairs of fixed contacts and two pairs of moving contacts are arranged in the disc-type vacuum arc extinguish chamber. One end of the insulated shaft is connected with a power source, and the other end of the insulated shaft extends to the inside of the disc-type vacuum arc extinguish chamber from the position of the circle center of the disc-type vacuum arc extinguish chamber to be connected with the middle part of a conductor rotating rod. The fixed contacts are fixed on bases of the fixed contacts, the moving contacts are respectively installed on end faces of two ends of the conductor rotating rod, and driven by rotation force of the insulated shaft, the conductor rotating rod drives the moving contacts to rotate clockwise and anticlockwise and connect any pair of fixed contacts so as to achieve the double-station function. The disc-type double-station vacuum arc extinguish chamber uses a motor or other power source to replace a traditional electromagnetic mechanism and has the advantages of being reasonable and compact in structure, small in size, low in cost and capable of connecting and disconnecting the higher voltage class and double-station function.

Vacuum interrupter is always towards development aspect miniaturization, voltage levels, low cost, and vacuum interrupter is applied in circuit breaker mostly.At present, most vacuum circuit-breakers is all the structure that adopts the additional operating mechanism of vacuum interrupter.How existing vacuum arc extinguish chamber structure easily breaks down to the too high large and moving component of operating mechanism complex structure, equipment volume that causes of operating mechanism precision prescribed, and due to structure distribution problem, its motion credibility is restricted; The way of contact of the dynamic/static contact of vacuum extinction chamber interior adopts Direct Action Type mostly, along with the raising of drop-out voltage, this type of structure of contact terminal is not well positioned to meet and cut-offs requirement, and its connecting-disconnecting function exists limitation, and vacuum interrupter only possesses the function of cut-offfing uniline mostly.And the vacuum circuit-breaker of minority double is also just connected moving contact one end in the time of open-circuit line with the earth, do not have the function of optionally connecting the loop that two-way electric pressure is identical.
Therefore, exploitation, research and production a kind of rational in infrastructure, compact, volume is little, low cost, can cut-off high voltage more, have the disc type vacuum interrupter of double function, be numerous potential users expect needed with market.
Summary of the invention
Object of the present invention is just to overcome the defect that existing vacuum arc-extinguishing chamber contact structure exists, a kind of novel disk-type double-station vacuum arc extinguishing chamber is provided, this disk-type double-station vacuum arc extinguishing chamber adopts 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 feature of voltage levels and double function.
The technical solution that the present invention provides is: this disk-type double-station vacuum arc extinguishing chamber, comprise disc type insulation crust, vacuum interrupter and be arranged on fixed contact and the moving contact of vacuum extinction chamber interior, be characterized in that described vacuum interrupter is the disc type vacuum interrupter being connected with shaft insulation, this disc type vacuum extinction chamber interior is provided with 2 pairs of fixed contacts and 2 pairs of moving contacts, described shaft insulation one end is connected with power source, the other end 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, on the end face at conductor bull stick two ends, be separately installed with moving contact, conductor bull stick drives moving contact just doing under the driving of shaft insulation revolving force, any a pair of fixed contact is connected in despining, to realize the function of double.
Object to better implement the present invention, the conductor bull stick main body of described disc type vacuum extinction chamber interior is linear pattern, two ends are arc line shaped, entire length is less than the diameter of disc type vacuum interrupter disk, 2 pairs of moving contacts are arranged on respectively on the end face at conductor bull stick two ends, conductor bull stick drives moving contact to do positive and negative rotation under the driving of shaft insulation revolving force, can make dynamic and static contact realize effectively contact or separate in the time that conductor bull stick rotates.
Object to better implement the present invention, the every pair of fixed contact (be 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 vacuum extinction chamber interior, ensured the synchronism that moving contact contacts, separates with 2 fixed contacts.
Object to better implement the present invention, (fixed contact a and fixed contact b are a pair of to 2 pairs of described fixed contacts, fixed contact c and fixed contact d for another to) access respectively in 2 loops, tunnel, by shaft insulation band moving-conductor bull stick, moving contact rotation, effectively connect any a pair of fixed contact, realized the function of double.
Compared with prior art, beneficial effect of the present invention is: 1. replaced traditional electromagnetic mechanism with motor or other power source, be convenient to control, save cost.
2. 2 groups of fixed contacts can access respectively 2 loops, tunnel, thereby can optionally connect any loop and realized the function of double.
4. along with the raising of electric pressure, can and adjust dynamic and static contact and improve disjunction distance and the linear velocity of dynamic and static contact on circumference of dynamic and static contact with the distance in insulation axle center by the diameter of increase disk, thereby ensure to open the requirement of distance, 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 arc control device internal structure is simple, compact, have improved the reliability of product.
