Abstract
The utility model discloses an outer sleeve pipe for the outdoor vacuum circuit breaker. A porcelain sleeve is arranged, an upper flange and a lower flange are respectively connected with the upper and lower ends of the porcelain sleeve, and a waterproof structure is matched with the upper and lower flanges. One part of the waterproof structure is a waterproof bulge arranged on the upper end surface of the upper flange, the other part is a waterproof groove matched with the lower end surface of the lower flange. The both ends of the porcelain sleeve are respectively embedded in the connecting holes of the opposite flange, and a metal sticking layer formed in a casting method is arranged between the outer wall of the porcelain sleeve and the inner wall of the connecting hole, to enable the porcelain sleeve to be integrated with the flanges at the both ends into a whole structure. The utility model can better solve the rain water leakage phenomenon, and the waterproof performance is greatly enhanced.
Description
Technical field
The utility model relates to a kind of outer tube of outdoor vacuum circuit breaker, the outer tube of the outdoor vacuum circuit breaker of particularly a kind of insulator and flange cast integral structure.
Background technology
At present, domestic ZW7 type outdoor vacuum opens circuit and generally adopts the structure of porcelain vase and flange formula, is specially the porcelain vase flange and wears spring formula structure.Flange and insulator adopt spring compression to fix, and make and leave the slit between the two, cause seeping phenomenon, rain leakage hidden danger is arranged, and this kind configuration switches integral quakeproof is poor, if switch is in case water inlet, the field service trouble, and maintenance time is longer, has had a strong impact on the reliability of power supply.
The utility model content
The utility model is to solve the technological deficiency of the water resistance difference that the prior art outer tube exists, and a kind of outer tube of outdoor vacuum circuit breaker is provided, and has the better waterproof energy.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of outer tube of outdoor vacuum circuit breaker is provided with insulator, and the two ends up and down of insulator are connected with upper flange and lower flange respectively, and above-mentioned upper flange and lower flange are provided with the waterproof construction that is used.
The part of above-mentioned waterproof construction is the waterproof projection that the upper surface of upper flange is provided with, and another part is the suitable with it waterproof groove that the lower surface of lower flange is provided with.
Above-mentioned waterproof projection and waterproof groove are circular ring.
The body two ends of above-mentioned insulator embed respectively in the connection holes of corresponding end flange, and the metal pickup layer that forms by pouring type is set between insulator outer wall and connection holes inwall.
The utility model major advantage is as follows:
Since on each insulator upper flange and lower flange, be provided with the waterproof construction that is used, as the waterproof projection that on the upper flange upper surface, is provided with, and the waterproof groove that on the lower surface of lower flange, is provided with.In a plurality of insulators joined the assembly use, the waterproof projection of wherein a certain insulator upper flange can embed in the waterproof groove of another insulator lower flange that joins with it, and this docking structure can solve the rain leakage phenomenon preferably, improves its waterproof ability greatly.And the whole anti-seismic performance of switch is improved, thereby improved the switch combination property.
In addition, form integral structure by casting of molten metal between insulator body and the flange, thoroughly solved gap problem.
Description of drawings
Figure is the structural principle schematic diagram of a kind of execution mode of the utility model.
Below in conjunction with accompanying drawing the utility model is described:
Embodiment
Referring to accompanying drawing, a kind of outer tube of outdoor vacuum circuit breaker, the upper end of its insulator 1 connects upper flange 2, and the lower end of insulator 1 connects lower flange 3.The two ends of insulator 1 embed respectively in the connection holes of flange 2,3 of corresponding end, and the metal pickup layer 4 that forms by pouring type is set between insulator 1 outer wall and each flange connection holes inwall, make insulator and the two end flanges formula structure that becomes one.In the upper surface of upper flange 2 waterproof projection 5 is set, waterproof projection 5 is circular, in the lower surface of lower flange 3 waterproof groove 6 is set, and waterproof groove 6 also is a circular ring.In a plurality of insulators joined the assembly use, each corresponding one group of waterproof projection was suitable with the waterproof groove, and promptly the waterproof projection of wherein a certain insulator upper flange can embed in the waterproof groove of another insulator lower flange that joins with it.
In the utility model, insulator upper flange and lower flange are provided with the waterproof construction that is used and do not limit to above-mentioned execution mode, and other many conspicuous variations can be arranged.
