Abstract
The utility model relates to a fixation and encapsulation pole column structure. The fixation and encapsulation pole column structure comprises a vacuum arc-extinguishing chamber arranged in a fixation and encapsulation pole column, the fixation and encapsulation pole column is based on a once-molding structure that the vacuum arc-extinguishing chamber and a bus connecting part are in individual epoxy pouring, is assembled on a breaker mechanism box individually after molding to form an individual breaker unit module, and then is assembled and molded with a solid insulating cover with a disconnecting switch. A first silicone rubber sealing sleeve is arranged on a connecting installing surface of the fixation and encapsulation pole column and the solid insulating cover, and the fixation and encapsulation pole column is also based on a mode that the vacuum arc-extinguishing chamber is arranged reversely. A touch finger base is poured directly at the lower part of a movable end of the vacuum arc-extinguishing chamber, and the bus connecting part is arranged between the vacuum arc-extinguishing chamber and an insulating pull rod via the touch finger base. The main buses are connected via watchband touch fingers, and a second silicone rubber sealing sleeve playing parts in buffer and sealing is arranged at the connection position of the main buses and the fixation and encapsulation pole column. The beneficial effects of the utility model are that: 1, the debugging is simple, the modular assembly is realized, and the assembly production rate can be improved substantially; 2, the space is reduced substantially, the structure is more complicated, and the power supply reliability is improved.
Description
Technical field
The utility model relates to solid insulation ring main unit field, is mainly a kind of pole structure.
Background technology
At present, along with the continuous popularization of solid insulation ring main unit, as the pole of main components, on market, sealing mode is different, mainly contains following two kinds: sealing or be potted in solid insulation cover, and in the large solid insulation cover of forced assembling.These two kinds of modes are all direct vacuum interrupter sealing, embedding, are pressed in solid insulation cover, that is to say that breaker unit and Disconnecting switch unit are all in an epoxy casting die cavity, and this structure exists the problem of inconvenient debugging.And current nearly all solid insulation ring main unit scheme, adopts the connected mode being flexible coupling between movable end of vacuum arc extinguishing chamber and isolation knife fixed contact, cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of debugging easy, reduce costs and realize modularization assembling, can greatly improve the pole structure of assembling productivity ratio.
The purpose of this utility model completes by following technical solution, it comprises the vacuum interrupter of being located in pole, described pole adopts vacuum interrupter and the independent epoxy casting one-shot forming of bus coupling part structure, after pole moulding, be assemblied in separately on circuit breaker mechanism case, form an independently breaker unit module, then with the solid insulation cover assembled formation that isolating switch is housed; Described pole with the connection face of solid insulation cover on device have the first silicone rubber seal cover; Described pole also adopts the mode of vacuum interrupter upside-down mounting, directly pours into a mould a button contact base in movable end of vacuum arc extinguishing chamber bottom, by this button contact base, bus coupling part is arranged in to the middle part of vacuum interrupter and insulated tension pole; Between described main bus bar and main bus bar, connect by watchband-shaped contactor, and main bus bar and pole junction are provided with the second silicone rubber seal cover of buffering and sealing function.
As preferably, between described main bus bar and main bus bar, connect by watchband-shaped contactor, main bus bar is arranged on the end cabinet of pole junction, at this end cabinet place, plug and end part seal cover is housed.
The beneficial effects of the utility model are: this structure, and 1, debugging is simple, and realize modularization assembling, can greatly improve assembling productivity ratio; 2, greatly reduce space, made structure more compact, improved power supply reliability.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is side-looking cross-sectional view of the present utility model.
Label in accompanying drawing is respectively: 1, the first silicone rubber seal cover; 2, pole; 3, plug; 4, end part seal cover; 5, the second silicone rubber seal cover; 6, insulated tension pole; 7, circuit breaker mechanism case; 8, main bus bar; 9, watchband-shaped contactor; 10, bus coupling part; 11, button contact base; 12, vacuum interrupter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1,2, this pole 2 adopts vacuum interrupter 12 and the independent epoxy casting one-shot forming structure of bus coupling part 10, after pole 2 moulding, can assemble separately circuit breaker mechanism case 7, and after debugging separately, form an independently breaker unit module, then assemble just passable with the solid insulation cover that isolating switch is housed.This structure, debugging is simple, and realizes modularization assembling, can greatly improve assembling productivity ratio.
The short circuit interruption of the vacuum interrupter 12 of using at present general solid insulation only has the defect of 20kA, this pole 2 adopts the vacuum interrupter 12 of particular design, operation-current reaches 25kA, and using the fixed contact of isolating switch directly as the quiet end of vacuum interrupter, this structure not only can be saved being flexible coupling between movable end of vacuum arc extinguishing chamber and the fixed contact of isolating switch, save cost, and because reduced by an electric faying surface, can greatly reduce loop resistance, improve power supply reliability.
This pole 2 also adopts the mode of vacuum interrupter upside-down mounting, directly pour into a mould a button contact base 11 in movable end of vacuum arc extinguishing chamber bottom, dexterously bus coupling part 10 is arranged in to the middle part of vacuum interrupter 12 and insulated tension pole 6, greatly reduce space, make structure more compact, and between main bus bar 8 and main bus bar 8, connect the mode that adopts direct watchband-shaped contactor 9 to connect, simple in structure, and adopt the mode of electric cable accessories connection to reduce widely cost than other producer.Main bus bar 8 has 5 bufferings of the second silicone rubber seal cover and sealing function with pole junction; If be arranged on the end cabinet of pole 2, and plug 3 and end part seal cover 4 are housed in end.And with solid insulation cover connection face, the first silicone rubber seal cover 1 being also housed, play buffering and sealing function.
The utility model is not limited to above-mentioned execution mode; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection range.
