In order to solve the defects in the prior art, without changing the original structure, shape and parameters of the traditional vacuum arc-extinguishing chamber, a high-strength alloy metal material is compounded on a movable conducting rod and a fixed conducting rod of the vacuum arc-extinguishing chamber in a mechanical method, thus preparing the movable conducting rod and the fixed conducting rod with a composite material structure. Therefore, the capability of the movable conducting rod and the fixed conducting rod for resisting the plastic deformation can be improved to maximum degree, so that the service life of the vacuum arc-extinguishing chamber can be prolonged.
Description
Technical field
This utility model relates to a kind of high and low pressure switch long-life vacuum arc control device, belongs 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 was subjected to is that tens thousand of inferior impacts forge.And traditional vacuum interrupter it is moving, static conductive rod is to satisfy the electric conductivity requirement all to make with the oxygen-free copper homogenous material, because the oxygen-free copper material is very soft, moving, static conductive rod forges down in this impact, and the generation plastic deformation is inevitable and is very serious, be in particular in moving, the static conductive rod chap, shorten, contact pressure diminishes, dynamic/static contact even virtual connection, and move, static conductive rod is encapsulated in again in the vacuum chamber of ceramic case, this distortion is difficult to observe and judge, if it is undiscovered, safeguard and untimelyly will bring serious threat to the safe operation of electrical system, even leading to major accident and economic loss, consequence is hardly imaginable.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of method of the reinforcement that compound non-magnetic stainless steel is made on the dynamic and static conducting rod that former oxygen-free copper is made is provided, and thoroughly solves the technical problem of its plastic deformation.
The object of the present invention is achieved like this: comprise by 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 on the dynamic and static conducting rod of oxygen-free copper material, reinforcement with the compound a kind of non-magnetic stainless steel making of the method for machinery, make 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 utility model, 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
Describe the detail and the operation principle of the device that proposes according to the present invention in detail below in conjunction with accompanying drawing
Contrast Fig. 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 connect the important function of circuit, a pair of dynamic and static contact (11) in ceramic case (10) under the vacuum environment, draw back different distances according to the electric pressure correspondence when (12) separate; Contact well guaranteeing in order to shorten 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; The very high but poorly conductive of the stainless steel machinery intensity of non-magnetic conduction.Thereby, compound with dynamic and static conducting rod (1), (3) that oxygen-free copper is made with the reinforcement of making of the stainless steel of non-magnetic conduction (2), utilize the complementation of different metal material characteristic, can improve the ability that dynamic and static conducting rod (1), (3) are resisted plastic deformation greatly, and then realize the long-life of vacuum interrupter.
So far, content of the present utility model and the concrete method of implementing have been described.
