Abstract
The invention, which belongs to high and low pressure electric appliance technology field, relates to a long-life vacuum interrupter used in high and low pressure switches. By using the interrupter of the invention, disadvantages in the prior art can be solved. A method for using a composite metal material is provided. Under the condition of not changing a structure, a shape and a parameter of a traditional vacuum interrupter, a mechanical method is used to place other metal materials with a high intensity in moving and static conducting rods of the vacuum interrupter so as to make the moving and static conducting rods with the composite material structure. A capability of resisting plastic deformation of the moving and static conducting rods of the vacuum interrupter can be increased maximumly so that a service life of the vacuum interrupter can be prolonged by multiples.
Description
Technical field
The present invention relates to a kind of high and low pressure switch and use the long-life vacuum arc control device, belong to the high and low pressure technical field of electric appliances.
Background technology
Vacuum interrupter requires the operating mechanism of high and low pressure appliance switch that its moving contact is given enough movement velocitys and pressure for satisfying electric property, and therefore, what the dynamic and static in actual use conducting rod of vacuum interrupter received is that tens thousand of inferior impacts forge.And its dynamic and static conducting rod of traditional vacuum interrupter is all processed with the oxygen-free copper homogenous material; Because the oxygen-free copper material is very soft; Dynamic and static conducting rod forges in this impact and takes place down that plastic deformation is inevitable and very serious, is in particular in dynamic and static conducting rod chap, shortens, contact pressure diminishes, dynamic/static contact even virtual connection.And dynamic and static conducting rod is encapsulated in the vacuum chamber of ceramic case; This distortion is difficult to observe and judge; If undiscovered, safeguard and untimelyly will bring serious threat to the safe operation of electrical system, even lead to major accident and economic loss, consequence is hardly imaginable.
Summary of the invention
The objective of the invention is to solve the deficiency that exists in the prior art, a kind of theory of using composite material is provided, insert the method for reinforcement for dynamic and static conducting rod, thoroughly solve the technical problem of its plastic deformation.
The objective of the invention is to realize like this: comprise by the vacuum interrupter body that moving conductive rod, reinforcement, static conductive rod, fairlead, retainer ring, moved end lid, bellows, moved end protective cover, shielding cylinder, ceramic case, moving contact, fixed contact, quiet end protective cover, quiet end cap are formed.
In the present technique solution: under the prerequisite that does not change vacuum interrupter original structure, shape, parameter; Just in the dynamic and static conducting rod of oxygen-free copper material; Method with machinery is inserted high-intensity other metalworks; Process the dynamic and static conducting rod of composite structure, improve the ability that it resists plastic deformation to greatest extent.
Adopt vacuum interrupter of the present invention, the obvious distortion of dynamic and static conducting rod in use can not take place in the appliance switch of composition, and the life cycle of high and low pressure appliance switch is significantly improved.

Embodiment
Specify the detail and the operation principle of the device that proposes according to the present invention below in conjunction with accompanying drawing
Map 1, Fig. 2, by: 1. moving conductive rod, 2. reinforcement, 3. static conductive rod, 4. fairlead, 5. retainer ring, 6. moved end lid, 7. bellows, 8. moved end protective cover, 9. shielding cylinder, the 10. vacuum interrupter body formed of ceramic case, 11. moving contacts, 12. fixed contacts, 13. quiet end protective cover 14. quiet end caps.
Vacuum interrupter is the critical component of appliance switch; In electric system, play disjunction and the important function of connecting circuit; A pair of dynamic and static contact (11) in ceramic case (10) under the vacuum environment, (12) draw back different distances according to the electric pressure correspondence separately the time, contact well guaranteeing for shortening pressure that thousands of newton also must be arranged after arcing time moving contact (11) must be made to close resultant motion and moving contact (11) and fixed contact (12) contact with the high speed of per second number meter during connection.Therefore, dynamic and static conducting rod (1), (3) be except being the good conductor of the big electric currents of thousands of amperes, also must can be good at bearing and transmit per second number meter, thousands of newton's mechanical impact force.Silver, copper, aluminium are good conducting metals but material behavior is all very soft; Steel, steel alloy hardness height but conductivity is very poor, visible, dynamic and static conducting rod (1), (3) are compound with reinforcement (2) is unique best bet.
So far, principle of the present invention and method have been described.
Claims (2)
1. a high and low pressure switch is used the long-life vacuum arc control device; Comprise the vacuum interrupter body of forming by: moving conductive rod (1), reinforcement (2), static conductive rod (3), fairlead (4), retainer ring (5), moved end lid (6), bellows (7), moved end protective cover (8), shielding cylinder (9), ceramic case (10), moving contact (11), fixed contact (12), quiet end protective cover (13), quiet end cap (14), it is characterized in that: the reinforcement (2) that alloy metal material was processed on moving conductive rod (1) that oxygenless copper material is processed and static conductive rod (3) were compound respectively.
2. high and low pressure switch according to claim 1 is used the long-life vacuum arc control device; It is characterized in that: in that the moving conductive rod that oxygenless copper material is processed (1) and static conductive rod (3) are compound respectively when going up the reinforcement (2) that alloy metal material processes; Comprise: alloy metal material is in inside; Oxygen-free copper externally with alloy metal material externally, oxygen-free copper is in inside.
