Abstract
The utility model discloses an outdoor high-voltage solid insulating load switch. The load switch comprises a sealed casing, wherein three inlet wire sleeves are arranged at one side of the casing, three outlet wire sleeves are arranged at the other side of the casing, and a seal pole group is arranged in the casing; the inner end of each inlet wire sleeve and the inner end of each outlet wire sleeve are connected with the seal pole group in a sealed manner. The seal pole group comprises more than three seal poles, each seal pole is connected with the corresponding inlet wire sleeve and outlet wire sleeve and is internally provided with a vacuum explosion chamber and a cavity, and the static contact of the vacuum explosion chamber and the wire inlet end are fixedly connected in the seal pole. The load switch of the utility model uses the seal poles instead of sulfur hexafluoride for insulation, which is more environmentally friendly, and high in safety.

In prior art, because environment is severe, easily there is condensation phenomenon in outdoor pole top switch, causes corrosion and insulation breakdown to lead to a disaster, and current solid insulation on-pole switch does not also have the product completely main conductive circuit being coated.In current open air, press on-pole switch to adopt sulfur hexafluoride gas or compound inslation (sealing adds air insulation) mode more.It is large especially that sulfur hexafluoride gas electric property is affected by the impurity such as electric field uniformity coefficient and moisture and sealing property, quite strict to the requirement of hermetically-sealed construction, component structure and the quality of sulfur hexafluoride gas own, also exists and reveal hidden danger.In addition, sulfur hexafluoride gas does not meet environmental requirement, should limit use, finally stops using; At aspects such as volume, cost, anti-dewings, also there is defect in compound inslation.
Thus, the inventor considers existing outdoor high voltage load switch internal structure to improve, and this case produces thus.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of outdoor high-voltage solid insulation on-load switch, and this on-load switch utilizes the insulation of the alternative original sulphur hexafluoride of pole of its every portion, environmental protection more in fact, and safe.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of outdoor high-voltage solid insulation on-load switch, this on-load switch comprises the housing of sealing, one side of described housing is provided with three groups of entrance bushings, the opposite side of described housing is provided with three groups of outlet casing tubes, in described housing, be provided with pole group, the inner inner and every group of outlet casing tube of every group of entrance bushing is tightly connected with described pole group respectively, described pole group comprises three above poles, each pole connects with corresponding entrance bushing and outlet casing tube, and in each pole, be provided with vacuum interrupter and die cavity, the fixed contact of described vacuum interrupter is fixedly connected with in described pole with end of incoming cables.
Further, each pole in described pole group is the pole of epoxy resin and/or silicon rubber moulding by casting, and then forms the insulation system between each pole.
Further, three above pole parallel distributions mutually in described pole group.
Further, the spacing A=135mm of every two the adjacent poles of described pole group.
Further, described each pole is stepped oval tubular structure, and these pole both sides are respectively arranged with end of incoming cables and the leading-out terminal of pegging graft with entrance bushing and outlet casing tube.
Further, described each pole vertically arranges, and the end of incoming cables of its both sides and leading-out terminal are in vertical distribution with this pole respectively.
Further, the distance B=148mm between described end of incoming cables and leading-out terminal.
Further, described end of incoming cables is positioned at pole top and is connected with described entrance bushing.
Further, described leading-out terminal is positioned at pole middle part and is connected with described outlet casing tube.
Further, height H=363 of described each pole.
The utility model adopts the sealing mode of all insulation, adopt the insulating material such as epoxy resin and silicon rubber to realize complete sealing, the mutual independence of three poles and tool be at regular intervals guarantees insulation effect, mould is simple, thoroughly use pole and inlet-outlet sleeve by main conductive circuit sealing, completely cut off outside moisture, dust, toy etc. and entered, this is the first heavy anti-condensation measure, has guaranteed the dielectric strength of switch.
