Abstract
The utility model relates to a high aluminum oxide electronic ceramic vacuum switch tube, which comprises a guide sleeve, a high aluminum oxide electronic ceramic tube, a movable end component, and a static end component. The utility model is characterized in that one end of the ceramic tube is connected with a stainless steel component through a copper transition ring, and then connected with a static conducting rod, the other end of the ceramic tube is connected with the corrugated tube of the movable end component through the copper transition ring, one end of the bearing rod of the movable end component is threaded through the middle hole of the guide sleeve, the contact of the movable end component is corresponding to the contact of the static end component, a shield barrel covered by the contacts of the movable end component and the static end component is connected with the inner wall of the high aluminum oxide electronic ceramic tube through the stainless steel component. The contact of the utility model is adopted Cu-Cr material, the voltage withstand strength, the withstanding current capability and the making current capability are enhanced, the electric life is long, the loop resistance is low, the cup shaped contact has the function of absorbing energy, to make the bounce value of the contact greatly reduced. The copper transition ring is arranged between the ceramic tube and the stainless steel, and the characteristic of weaker elasticity and yield strength is adopted, to ensure the sealing intensity and the sealing.
Description
Technical field
The utility model relates to a kind of vacuum switch tube, especially relates to a kind of to the improved high-alumina electronic ceramic of structure of contact terminal vacuum switch tube.
Background technology
Vacuum switch tube belongs to the passive electrical vacuum device, and is supporting with all kinds of different switching mechanisms and form the high, medium and low voltage vaccum electric apparatus, as vacuum circuit-breaker, vacuum load switch, vacuum contactor, vacuum recloser, vacuum sectionalizer.It is widely used in each industrial circle such as metallurgy, electric power, oil, electric railway.
Because it is little that vacuum switch has a volume, function admirable, pollution-free, the life-span long, safe and reliablely be suitable for series of advantages such as frequent operation and developed rapidly.And that vacuum switch tube is used for the contact material and the contact design of vacuum load switch is most important, because it directly influences vacuum tube contact gap proof voltage level, short circuit current making capability, simultaneously closely related with vacuum tube electrocorrosion-resisting performance, melting welding power and rated current admittance ability, Chopping Current again, general contact material commonly used is a tungsten copper series, its compressive resistance, withstand current ability, making current ability, and the big shortcoming of loop resistance is arranged.The design of structure of contact terminal directly has influence on the connecting-disconnecting function and the electric life of circuit breaker, the main dull and stereotyped dock of existing structure of contact terminal, this structural formula is fairly simple, but when the switch closing operation, do not cushion, can't absorb mechanical energy, thereby be easy to generate contact bounce, bring a lot of troubles, and too high spring can be drawn contact melting welding and be reduced switch life to assembling and setting.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model provides the high-alumina electronic ceramic vacuum switch tube of a kind of new contact material and structure of contact terminal.
To achieve these goals, the utility model adopts following technical scheme:
High-alumina electronic ceramic vacuum switch tube, it comprises fairlead, high-alumina electronic ceramic pipe, the moved end assembly, quiet end assembly, it is characterized in that: an end of earthenware is crossed the plating ring by copper and is connected with stainless steel part, be connected with static conductive rod again, the other end of high-alumina electronic ceramic pipe is also crossed the plating ring by copper and is connected with the bellows of moved end assembly, pole one end of moved end assembly passes the mesopore of fairlead, the contact of moved end assembly is corresponding with the contact of quiet end assembly, and the shielding cylinder that the contact and the Contact Cover of quiet end assembly of moved end assembly is connected with high-alumina electronic ceramic inside pipe wall by stainless steel part.
Therefore, the utility model contact adopts copper chromium material, compressive resistance, withstand current ability, making current ability strengthen, electric life is long, and the less performance of loop resistance is arranged, and the cup-shaped design of contact has the absorption energy, the contact bounce value is declined to a great extent, copper is set between earthenware and stainless steel crosses the plating ring, utilize the elasticity and the yield strength features of smaller of copper, guarantee sealing strength and sealing.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of contact schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1,2, the technical solution of the utility model is described in further detail.
High-alumina electronic ceramic vacuum switch tube, it comprises fairlead 5, high-alumina electronic ceramic pipe 2, moved end assembly 1, quiet end assembly 4, it is characterized in that: an end of earthenware 2 is crossed the plating ring by copper and is connected with stainless steel part 7, be connected with static conductive rod again, the other end of high-alumina electronic ceramic pipe 2 is also crossed the plating ring by copper and is connected with the bellows of moved end assembly 1, pole one end of moved end assembly 1 passes the mesopore of fairlead 5, the CuCr25 contact 6 of moved end assembly 1 is corresponding with the CuCr25 contact 6 of quiet end assembly, and the shielding cylinder 3 that the CuCr25 contact 6 and the CuCr25 contact 6 of quiet end assembly of moved end assembly covered is connected with high-alumina electronic ceramic pipe 2 inwalls by stainless steel part 8.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
