Abstract
The utility model belongs to the field of manufacturing technology of circuit breaker fittings of a high-voltage switch cabinet, and particularly relates to an epoxy-enclosed contact arm sleeve, which includes a tubular contact arm; the outer wall of the contact arm is wrapped and sealed by epoxy resin integrated with the contact arm; the outer wall of the epoxy resin forms a plurality of circles of outward convex creep distances; the upper opening of the epoxy resin forms a contact arm seal, the outer diameter of the contact arm seal is larger than that of the epoxy resin, and an annular sealing step is formed inside the contact arm seal; and the lower opening of the epoxy resin forms a tulip contact guard shield, the lower end of the contact arm is arranged inside the tulip contact guard shield and the outer diameter of the tulip contact guard shield is larger than that of the epoxy resin. The epoxy-enclosed contact arm sleeve provided by the utility model is matched in a fixedly-sealing pole or an insulation cylinder used in a vacuum circuit breaker, thereby solving the electric-discharge and breakdown problems caused by fit clearance and internal air gap generated when an original contact arm is used in matching with an outer sleeve, a vulcanization layered contact arm or a silicon-added rubber sleeve contact arm, as well as the electric-discharge phenomenon caused by clearance generated when the fixedly-sealing pole or the insulation cylinder is matched with the original contact arm.
Description
Technical field
The utility model belongs to the accessory manufacturing technology field of high-voltage switch cabinet breaker, particularly a kind of insulating cylinder that is applicable to the high-tension switch cabinet vacuum circuit-breaker and pole supporting epoxy seal the contact arm cover.
Background technology
Vacuum circuit-breaker comprises pole or insulating cylinder, insulated tension pole, contact arm, insulating sleeves or vulcanizes contact arm or add silicone rubber jacket contact arm etc., contact arm is the requisite important accessory of pole or insulating cylinder fit on, contact arm can not use separately, must or vulcanize contact arm or add the silicone rubber sleeve contact arm with insulating sleeves and be used, thereby reach the compound inslation effect by assembling by the insulation effect of simple layer.But in contact arm and structure that other parts match, must have the air gap, thereby be easy to generate discharge, punch-through, and the dielectric strength that cooperates is also not enough, resistivity is extremely low, easy aging, problems such as the supporting installation of multicomponent is loaded down with trivial details.
Summary of the invention
The utility model discloses a kind of epoxy and seal the contact arm cover, it is matched in employed pole or insulating cylinder in the vacuum circuit-breaker, it has solved original contact arm cooperation oversleeve or sulfuric horizon or has added discharge, the breakdown problem that the silicone rubber sleeve contact arm exists fit clearance and internal air gap to cause, and has also solved pole or insulating cylinder simultaneously and has overlapped the electric discharge phenomena that have the gap when cooperating and produce with original contact arm.
The utility model is taked following technical scheme: epoxy is sealed the contact arm cover, comprises contact arm, contact arm in a tubular form, the outer wall of contact arm is sealed an epoxy resin, epoxy resin and contact arm are integral; The epoxy resin outer wall forms the creep distance of a few evaginations; The last interruption-forming contact arm of epoxy resin seals, and the external diameter that contact arm seals is bigger than epoxy resin, forms one ring packing step in contact arm seals; The following interruption-forming Mume flower contact guard shield of epoxy resin, the lower end of contact arm is in the Mume flower contact guard shield, and Mume flower contact guard shield external diameter is greater than the external diameter of epoxy resin.
As preferably, described epoxy is sealed the contact arm cover, and contact arm seals the inner spill annular groove that forms downwards, and the inner side edge of annular groove forms described ring packing step.
As preferably, described epoxy is sealed the contact arm cover, logical spill during Mume flower contact guard shield longitudinal section is, and the lower end of contact arm is passed at the middle part.
As preferably, described epoxy is sealed the contact arm cover, and creep distance is the 3-6 circle.
As preferably, described epoxy is sealed the contact arm cover, and creep distance is 4 circles.
The utility model epoxy is sealed the contact arm cover and is matched in employed pole or insulating cylinder in the vacuum circuit-breaker, its fitting operation is very easy, sealing ring need only be inserted in the contact arm cover reserves on the step, again epoxy is sealed contact arm cover integral installation on pole or the insulating cylinder/following outlet on, compress and be in place, just can play the integral sealing insulating effect, eliminate discharge, punch-through that original technology exists, guarantee that electric equipment moves safely and reliably.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical structure cutaway view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, 2, the utility model epoxy is sealed the contact arm cover and is comprised contact arm 1, epoxy resin 2, and contact arm 1 in a tubular form, its outer wall is sealed one deck epoxy resin 2, and 1 of epoxy resin 2 and contact arm are sealed and matched, and both form integrated, therefore, when using, need not additionally to increase sheath.It adopts epoxy layer to replace in original technology the cooperation overcoat that adopts other material to make, thereby has electric strength height, good insulating, decay resistance is good and thermal stability is high advantage.
The middle and upper part of epoxy resin 2 outer walls forms the creep distance 4 of four circle evaginations, sets up suitable creep distance in contact arm cover extexine, to solve the creepage phenomenon of contact arm cover.The last interruption-forming contact arm of epoxy resin 2 seals 6, and contact arm seals that 6 external diameter is bigger than the stage casing external diameter of epoxy resin 2, and contact arm seals the 6 inner spill annular grooves 7 that form downwards, and the inner side edge of annular groove 7 forms ring packing step 5 one.When epoxy is sealed the contact arm cover and is matched in pole or insulating cylinder, sealing ring need only be inserted on the sealed step of contact arm cover reservation, again epoxy is sealed contact arm cover integral installation on pole or insulating cylinder/following outlet, its simple installation, and can arc protection creepage, and have strengthened sealing property.
The following interruption-forming Mume flower contact guard shield 3 of epoxy resin 2, the opening of Mume flower contact guard shield 3 down, logical concave shape during the cross section is, in logical portion promptly pass the lower end of contact arm 1.Mume flower contact guard shield 3 covers in the lower end of contact arm 1 in it, and its external diameter is greater than the stage casing external diameter of epoxy resin 2.Mume flower contact guard shield 3 is used for the protective cover arc protection, guarantees insulation property.
Epoxy of the present utility model is sealed the contact arm cover and has been concentrated many performances, can satisfy vacuum circuit-breaker adapted demand fully, can guarantee that electric equipment moves safely and reliably.
The above-mentioned explanation of just the preferential embodiment of the utility model being done; and be not that conduct is to restriction of the present utility model; those skilled in the art will be appreciated that any conversion, modification that the utility model is done all falls into protection range of the present utility model.
