6Circuit breaker is a main product.SF
6Gas is appointed as a kind of strong greenhouse gases by Kyoto Protocol, and advises forbidding SF in the year two thousand thirty comprehensively
6Gas.Vacuum circuit-breaker has environmental protection, and the properties of product advantages of higher is a main product in middle pressure grade at present.Replace SF with high-pressure vacuum breaker
6Circuit breaker is a kind of good selection.Vacuum circuit-breaker short circuit current cut-off aspect ability outstanding, but improve being not easy aspect the rated current parameter.The utility model improves the rated current of high-pressure vacuum breaker with rational radiator structure under the prerequisite that does not change vacuum interrupter.This scheme did not worldwide all adopt in the high-pressure vacuum breaker of 72.5kV and above grade.
Summary of the invention
The purpose of this utility model is intended to propose a kind of scheme that improves high-pressure vacuum breaker rated current grade under the constant prerequisite of vacuum interrupter.
The technical solution that realizes foregoing invention is, this has the high-pressure vacuum breaker of high rated current grade, the vacuum interrupter pole by porcelain bushing as insulation column, vacuum interrupter is housed in porcelain bushing, the two ends of vacuum interrupter have static conductive rod and moving conductive rod respectively, last conducting ring and upper flange are arranged around the static conductive rod, and be provided with the upper connecting terminal that is connected with last conducting ring in the porcelain bushing outside; Around the moving conductive rod following conducting ring and conductive supporting are arranged, there is lower flange the below of conductive supporting, and passes through the lower connecting terminal of conducting ring connection porcelain bushing outside down; It is characterized in that above upper flange, also having first radiator, around lower flange, be provided with second radiator, the insulating oil as heat radiation is arranged in the space between porcelain bushing and vacuum interrupter and porcelain bushing and conductive supporting.
The utility model can significantly improve the rated current performance of high-pressure vacuum breaker.

Embodiment
The embodiment that provides below in conjunction with accompanying drawing and inventor is described in further detail the utility model.
The vacuum interrupter pole structure of high-pressure vacuum breaker of the present utility model as shown in Figure 1.Constitute the vacuum interrupter poles by upper connecting terminal 1, lower connecting terminal 2, porcelain bushing 3, upper flange 4, lower flange 5, last conducting ring 6, following conducting ring 7, vacuum interrupter 8, insulating oil (as silicone oil) 9, conductive supporting 10, first radiator 11, second radiator 12.The two ends of vacuum interrupter 8 have static conductive rod 13 and moving conductive rod 14 respectively.
The radiator fin 1101,1201 of first radiator 11, second radiator 12 radially distributes on radiator, and structure chart is referring to Fig. 2, Fig. 3; Can certainly equidistant parallel distribution.
Electric current can arrive upper flange 4 via upper connecting terminal 1, arrives moving conductive rod 14 through vacuum interrupter 8 through last conducting ring 6 again to static conductive rod 13 again, and process conducting ring 7 down arrives conductive supporting 10 again, is flowed out by lower flange 5 and lower connecting terminal 2 at last.Current direction also can be opposite with above-mentioned direction.Porcelain bushing 3 plays the effect of mechanical support.In the space of insulating oil (as silicone oil) between porcelain bushing 3 and vacuum interrupter 8 and porcelain bushing 3 and conductive supporting 10, it mainly plays insulating effect, also plays the effect of heat loss through convection simultaneously.First radiator 11 is contained in above the upper flange 4, and second radiator 12 can be installed in top, the following or side of lower flange 5.Static conductive rod 13, go up conducting ring 6, upper flange 4 and first radiator 11 and mainly play the effect that the heat with vacuum interrupter top sheds; Moving conductive rod 14, down conducting ring 7, conductive supporting 10, lower flange 5 and second radiator 12 mainly play the effect that the heat with the vacuum interrupter bottom sheds.They are the critical components that make that the rated current of high-pressure vacuum breaker improves.
The fin of first radiator 11, second radiator 12 is radial or parallel distribution to reach better heat radiating effect, further improves the load current value of high-pressure vacuum breaker.
The inventor has carried out temperature field analysis to above embodiment: first radiator 11 is got 12 radiator fins, the high 100mm of radiator fin, and second radiator 12 is got 24 radiator fins, the high 100mm of radiator fin.By rated current is 2000A.Do not install under the situation of first radiator 11 and second radiator 12, the maximum temperature in the vacuum interrupter pole is 118 degrees centigrade; Under the situation that first radiator 11 and second radiator 12 are installed, the maximum temperature in the vacuum interrupter pole is 88 degrees centigrade.As seen, use the utility model can significantly improve the rated current performance of high-pressure vacuum breaker.
