Description
Technical field
The utility model relates to a kind of compound insulating sleeve and uses the gas insulation switch cabinet of this sleeve pipe.
Background technology
Along with insulating material technological progress, insulated product based on epoxy resin has obtained tremendous development, but because epoxy resin has certain limitation at aspects such as mechanical strength, electric insulations, make product itself have that volume is large, Heavy Weight, in production and processing, exist pollution, material itself not to degrade, do not meet the shortcomings such as environmental requirement.Compound insulating sleeve as shown in Figure 1, this sleeve pipe comprises the insulating coating 102 of coaxial package in conducting rod 101 and periphery thereof, wherein the material of insulating coating 102 is epoxy resin, in order to improve the fail safe of product, the integrated pouring technology of the general implementation of compound insulating sleeve of current 12kV electric pressure, but the limitation due to epoxy resin mechanical performance and electric property, make the cast layer thickness of compound insulating sleeve generally be greater than 8-10mm, thereby caused that compound insulation sleeve pipe volume is slightly large, Heavy Weight and other a series of shortcomings.
Utility model content
The purpose of this utility model is to provide little, the lightweight compound insulating sleeve of a kind of volume, and a kind of gas insulation switch cabinet that uses this compound insulating sleeve is also provided simultaneously.
In order to realize above object, in the utility model, the technical scheme of compound insulating sleeve is as follows:
Compound insulating sleeve, comprise insulating coating, insulating coating is the body of engineering plastics material, the wall thickness of insulating coating is 3-5mm, in the periphery of insulating coating, convex with the insulation cluster parachute being intervally arranged, in insulating coating periphery, also convex with the annular ring flange in middle part, the two ends of insulating coating are 2:1 to the ratio of distances constant of ring flange.
Engineering plastics are fiberglass reinforced plastics.
In the utility model, the technical scheme of gas insulation switch cabinet is as follows:
Gas insulation switch cabinet, the compound insulating sleeve that comprises cabinet and interior setting thereof, compound insulating sleeve comprises insulating coating, insulating coating is the body of engineering plastics material, the wall thickness of insulating coating is 3-5mm, in the periphery of insulating coating, convex with the insulation cluster parachute being intervally arranged, also convex with the annular ring flange in middle part in insulating coating periphery, the two ends of insulating coating are 2:1 to the ratio of distances constant of ring flange.
Engineering plastics are fiberglass reinforced plastics.
In the utility model, the insulating coating of compound insulating sleeve is the body of engineering plastics material, good insulating performance and machining property due to engineering plastics, so in the situation that guarantee the same insulation property of insulating coating, the wall thickness of insulating coating can dwindle 30%-50%, thereby the overall volume of whole compound insulating sleeve is reduced, weight saving, and the hot strength of engineering plastics is more than 90MPa, dielectric breakdown strength is more than 30kV/mm, heat distortion temperature is more than 200 ℃, thereby make compound insulating sleeve there is more excellent mechanical performance.In addition, engineering plastics can reclaim use, simultaneously by engineering plastics when making insulating coating, compared with prior art saved heating fixed line link, make the manufacture process environmental protection and energy saving more of compound insulating sleeve.
