Description
Technical field
This utility model relates to insulator technology field, a kind of anti-flashover through-wall sleeve.
Background technology
nullExisting anti-flashover through-wall sleeve is the Electric Field Distribution improving region through walls，Prevent the generation of flashover，Typically can press shading ring and grounded shield ring embedded the setting high of sleeve body，And high-tension shielding ring and grounded shield ring concentric sheathed，But，In actual application，There is a weak point in existing anti-flashover through-wall sleeve: owing to high-tension shielding ring and grounded shield ring are mesh cylinder，Therefore both of which is the most soft，And mesh is more，And the sleeve body of anti-flashover through-wall sleeve is made by cast，Therefore when casting sleeve body，High-tension shielding ring and grounded shield ring not only easy deformation of unevenness under the washing away of potting syrup，But also it is susceptible to displacement，Cause keeping concentric between the two，Above-mentioned these all can cause the distance between high-tension shielding ring and grounded shield ring uneven，Thus not only result in the non-uniform electric between high-tension shielding ring and grounded shield ring，And be also easy to insulation breakdown phenomenon at a distance of nearer position at high-tension shielding ring and grounded shield ring，And then had a strong impact on safety in utilization and the service life of anti-flashover through-wall sleeve.
Utility model content
The technical problems to be solved in the utility model is, there is provided a kind of when sleeve body is poured into a mould, it is not only able to effectively prevent high-tension shielding ring and grounded shield ring from deforming, and high-tension shielding ring and grounded shield ring between the anti-flashover through-wall sleeve of concentricity can also be effectively ensured.
For solving above-mentioned technical problem, this utility model provides the anti-flashover through-wall sleeve of a kind of following structure: include sleeve body, high-tension shielding ring and grounded shield ring it is provided with in sleeve body, high-tension shielding ring and grounded shield ring concentric are sheathed, wherein, being additionally provided with insulated sleeve between high-tension shielding ring and grounded shield ring, the internal perisporium of insulated sleeve is close to high-tension shielding ring, and the periphery wall of insulated sleeve is close to grounded shield ring.
Anti-flashover through-wall sleeve described in the utility model, wherein, insulated sleeve is coated with semiconducting paper.
Anti-flashover through-wall sleeve described in the utility model, wherein, the axial length of insulated sleeve is equal with the axial length of grounded shield ring.
Anti-flashover through-wall sleeve described in the utility model, wherein, the axial two ends of grounded shield ring are equipped with ground connection shaping loop.
Anti-flashover through-wall sleeve described in the utility model, wherein, the axial length of high-tension shielding ring is more than the axial length of grounded shield ring.
Anti-flashover through-wall sleeve described in the utility model, wherein, the axial two ends of high-tension shielding ring are equipped with high pressure shape circle.
Anti-flashover through-wall sleeve described in the utility model, wherein, insulated sleeve is made up of epoxy resin.
nullAfter using said structure，Compared with prior art，This utility model has the advantage that owing to being additionally provided with insulated sleeve between high-tension shielding ring and grounded shield ring，The internal perisporium of insulated sleeve is close to high-tension shielding ring，The periphery wall of insulated sleeve is close to grounded shield ring，Therefore when casting sleeve body，Under the effectively support of insulated sleeve，Not only high-tension shielding ring and grounded shield ring will not produce deformation of unevenness again，And can also remain concentric between high-tension shielding ring with grounded shield ring，So that the distance between high-tension shielding ring and grounded shield ring can keep uniform，And then it is not only able to the electric fields uniform distribution ensureing between high-tension shielding ring and grounded shield ring，And generation insulation breakdown can also be prevented effectively between high-tension shielding ring and grounded shield ring，Ensure that safety in utilization and the service life of the anti-flashover through-wall sleeve of this utility model.
The anti-flashover through-wall sleeve of this utility model is coated with semiconducting paper on insulated sleeve can improve the Electric Field Distribution between high-tension shielding ring and grounded shield ring further.
The axial length of insulated sleeve is equal with the axial length of grounded shield ring can make insulated sleeve effectively support whole grounded shield ring such that it is able to is prevented effectively from grounded shield ring and produces deformation of unevenness.
Be arranged on grounded shield annulate shaft and be not only able to contribute to the sizing of grounded shield ring to the ground connection shaping loop at two ends, and ground connection shaping loop can also blocking insulated sleeve, consequently facilitating the location between grounded shield ring and insulated sleeve.
The axial length of high-tension shielding ring is more than the axial length of grounded shield ring, the coverage rate making high-tension shielding ring is bigger, it is thus possible to improve the Electric Field Distribution of the anti-flashover through-wall sleeve of this utility model further, prevent from occurring between high-tension shielding ring and grounded shield ring insulation breakdown.
The high pressure shape circle at the axial two ends being arranged on high-tension shielding ring is not only able to contribute to the sizing of high-tension shielding ring, and can also be prevented effectively from insulated sleeve and slip from high-tension shielding ring.
