Description
Technical field
The utility model relates to a kind of vacuum switch, in particular to a kind of rapid cooling type vacuum switch.
Background technique
Vacuum switch is one of the key element on pulse power system, directly decides the good of pulse power system performance
It is bad.The switchgear, for one group, by two gas nozzles on side wall, is full of special gas in switch internal with ten vacuum switches
Body is then applied in pulse power device.Since the use condition of the product is harsh, it is desirable that the voltage of vacuum switch entirety point
Cloth is uniform, good air-tightness, fast conducting performance, the reliability cut-off etc..The vacuum switch produced and used at present, touching
It is high vacuum environment around head, the heat generated at contact can only lean on the heat transfer of heat radiation and conducting rod to be dispersed into environment,
Heat-sinking capability is limited, causes current-carrying capability limited, it is more difficult to be used for high current occasion.
Utility model content
The purpose of this utility model, which is that, provides a kind of structurally reasonable, good cooling results, the rapid cooling of high reliablity
Type vacuum switch.
To achieve the goals above, the technical solution adopted in the utility model is such：The fast quickly cooling of the utility model
But type vacuum switch, including porcelain bushing, two end cap, two conducting rods, two contacts, bellows and shielding case, two end cap are set respectively
It sets at porcelain bushing both ends, two conducting rods are arranged in porcelain bushing, and end cap is extended in end, and two contacts are separately positioned on two
The adjacent end of conducting rod, the porcelain bushing both ends are provided with transition rings, and described bellows one end is fixed in transition rings, pottery
Insulator inside pipe wall is provided with annular convex platform close to the position of bellows, and the shielding case is fixed on annular convex platform, the end cap
Inner wall is provided with enhancement layer, further includes two evaporators and condenser, and two evaporators are separately positioned on two conducting rods far from contact
End, evaporator are connected by the inlet tube and outlet tube of outlet pipe and liquid back pipe road and condenser.
Preferably, the transition rings are detachably connected with porcelain bushing.
Preferably, being provided with heat-conducting layer between the evaporator and conducting rod.
Compared with prior art, the utility model has the advantage of：The utility model is structurally reasonable, good cooling results, can
By property height, transition rings and enhancement layer are set, have air-tightness good, intensity is high, and good reliability, insulation effect is good, and the operation is stable prolongs
The advantages that its long service life, is arranged evaporator and condenser, cooling effect can be improved, so that vacuum switch current-carrying capability is more
Greatly, Natural Circulation between evaporator and condenser does not need external energy supply, while evaporating liquid dielectric level height, even if letting out
Leakage, will not influence the dielectric level of vacuum interrupter.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to Fig. 1, the rapid cooling type vacuum switch of the utility model, including porcelain bushing 1, two end cap 2, two conducting rods
3, two contacts 4, bellows 5 and shielding case 7, two end cap 2 are separately positioned on 1 both ends of porcelain bushing, and two conducting rods 3 are arranged in ceramics
In casing 1, and end cap 2 is extended in end, and two contacts 4 are separately positioned on the adjacent end of two conducting rods 3, the porcelain bushing 1
Both ends are provided with transition rings 9, and described 5 one end of bellows is fixed in transition rings 9, and 1 inner wall of porcelain bushing is close to the position of bellows 5
It installs and is equipped with annular convex platform 6, the shielding case 7 is fixed on annular convex platform 6, and 2 inner wall of end cap is provided with enhancement layer 8, also
Including two evaporators 10 and condenser 12, two evaporators 10 are separately positioned on two ends of the conducting rod 3 far from contact 4, evaporator
10 are connect by outlet pipe 13 and liquid back pipe road 14 with the inlet tube of condenser 12 and outlet tube, the transition rings 9 and ceramics
Casing 1 is detachably connected, and is provided with heat-conducting layer 11 between the evaporator 10 and conducting rod 3.
The utility model is structurally reasonable, good cooling results, high reliablity, and transition rings 9 and enhancement layer 8 is arranged, and has airtight
Property it is good, intensity is high, and good reliability, insulation effect is good, the operation is stable, and the advantages that prolonging its service life, 10 He of evaporator is arranged
Condenser 12, can be improved cooling effect, so that vacuum switch current-carrying capability is bigger, it is natural between evaporator 10 and condenser 12
Circulation, does not need external energy supply, while evaporating liquid dielectric level height, even if leaking, will not influence vacuum interrupter
Dielectric level.
