Description
Technical field
The utility model relates to solid insulation ring main unit field, is mainly a kind of Split type solidified pole rod structure.
Background technology
From solid insulation ring main unit by national grid in 2011 listing in since " first emphasis of State Grid Corporation of China spread the new technique catalogue ", complete company of Ge great Chevron Research Company (CRC) and switchgear plant is is all researching and developing solid insulation ring main unit product energetically, everybody scheme is different, and structure is also not quite similar.Press isolating switch classification, can divide isolation, lower isolation scheme, and two between two, three station schemes.
Isolation scheme in what is called is exactly the upper end of isolating switch at circuit breaker (on-load switch), namely in bus bar side; So-called lower isolation scheme is exactly the lower end of isolating switch at circuit breaker (on-load switch), namely in outlet (inlet wire) side.These two kinds of modes of connection respectively have feature separately, electrical network to these two kinds of modes of connection according to operational mode different application in different distribution network systems.
What is called is station between two, be exactly isolating switch be two stations, namely only have close a floodgate with two positions of ground connection, without isolated location; Its isolated location is by isolating switch at closing position, and cut-off breaker (on-load switch), isolates by vacuum interrupter.So-called three stations are exactly that isolating switch itself has combined floodgate, isolation, three positions of ground connection.The current grid company of station is not too admitted between two, because vacuum insulation fracture only has 8-9mm, not visible, and just in case vacuum interrupter gas leakage, its isolation fracture is just more unreliable.
At present, solid insulation ring main unit manufacturer, has eliminated station between two mostly, adopts three station schemes; But be upper isolation, or be lower isolation, can not meet the requirement of network system completely.And mostly producer adopts the structure of single-phase solid insulation cover at right angle setting Direct Action Type operating mechanism, solid insulation cover height is high, volume is larger, and content of epoxy resin is large, and cost is high.
At present, rated current 630A all can only accomplish in most solid insulation ring main unit producer, and rated short circuit drop-out current 20kA can not meet large capacity requirement in distribution network systems and reach the requirement of 1250A/31.5kA completely.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the Split type solidified pole rod structure that a kind of compact conformation, environmental protection is provided, reduces costs.
The purpose of this utility model completes by following technical solution, it comprises tri-station isolating switch, insulated tension pole and the contact be located in Split type solidified pole rod, and the mode that described Split type solidified pole rod adopts positive level to install is connected with operating mechanism; Spring touch finger is fixed in button contact base, described insulated tension pole is fixed on the termination of vacuum interrupter by button contact base and spring touch finger, described tri-station isolating switch one end is rotatably connected on button contact base, and its other end joins with the contact of being located in Split type solidified pole rod respectively by leading screw; Two described contacts are individually fixed in the both sides in Split type solidified pole rod, and employing is isolated symmetrical up and down.
As preferably, the below of described Split type solidified pole rod is provided with the observation window for seeing tri-station isolating switch running status.
The beneficial effects of the utility model are: have compact conformation, environmental protection, greatly reduce cost, met the service requirement of grid company completely.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks cross-sectional view.
Label in accompanying drawing is respectively: 1, Split type solidified pole rod; 2, button contact base; 3, spring touch finger; 4, insulated tension pole; 5, tri-station isolating switch; 6, leading screw; 7, observation window; 8, contact; 9, vacuum interrupter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in Figure 1, the utility model comprises tri-station isolating switch 5, insulated tension pole 4 and the contact 8 be located in Split type solidified pole rod 1, the mode that described Split type solidified pole rod 1 adopts positive level to install is connected with operating mechanism, the transmission distance of itself and operating mechanism is short, therefore compact conformation, its content of epoxy resin is minimum in current solid insulation ring main unit, and not only environmental protection also greatly reduces cost; Spring touch finger 3 is fixed in button contact base 2, described insulated tension pole 4 is fixed on the termination of vacuum interrupter 9 by button contact base 2 and spring touch finger 3, described tri-station isolating switch 5 one end are rotatably connected on button contact base 2, and its other end joins with the contact 8 of being located in Split type solidified pole rod respectively by leading screw 6.Two described contacts 8 are individually fixed in the both sides in Split type solidified pole rod 1, and employing is isolated symmetrical up and down.The below of described Split type solidified pole rod 1 is provided with the observation window 7 for seeing tri-station isolating switch running status.
This Split type solidified pole rod 1 adopts tri-station isolating switch 5, and adopts and isolate up and down symmetric design in the time of design, can, by the installation that spins upside down of Split type solidified pole rod 1, realize upper and lower isolation scheme.Such structure, can, according to concrete distribution network systems demand, be assembled into isolation scheme or lower isolation scheme, has met the service requirement of grid company completely.
In this Split type solidified pole rod when design,, its technical parameter and product structure all design by 1250A/31.5kA, and 1250A/31.5kA and two kinds of specifications of 630A/20kA realize same pair of mould structure.When wherein this specification of 630A/20kA is produced, only vacuum interrupter and conductor need be changed and just can realize: vacuum interrupter makes 630A/20kA into, and conductor makes aluminium conductor into by original T2 red copper conductor, and size is all constant.This design, not only can meet the demand of grid company for large electric current (1250A/31.5kA), also can realize the demand of conventional little electric current (630A/20kA); And two kinds of specifications share one pair of mould, have greatly reduced mould input cost.
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.
