Abstract
The utility model discloses a compound post insulators of porcelain, its characterized in that: have gold utensil, cement glue, ceramic stem, coupling agent layer, take the silicone rubber jacket of full skirt, the cement glue is firmly bound gold utensil and ceramic stem become integratively, and an organic whole is cast through coupling agent layer complex to the silicone rubber jacket of taking the full skirt on the outward appearance of ceramic stem, on the ceramic stem not regional the range estimation for the ceramic stem of composite silicone rubber section distinguish, the utility model discloses with present transformer substation pottery ( glass ) post insulators relatively, light in weight, self -cleaning can the reinforce, creepage distance is big, can realize non -maintainingly in the electric wire netting fortune, reduces the running cost of electric wire netting, safe and reliable, but the wide application has better economic benefits and social in 35kV to 1000kV transformer substation.
Description
Technical field
The utility model relates to the transformer station of the generating and transmitting system of electric power system, special relevant to the post insulator of high pressure, superhigh pressure and ultra-high voltage transformer station, is specifically a kind of porcelain composite post insulator.
Background technology
Post insulator is the visual plant of transformer station, and post insulator used is at present pottery (glass) post insulator mainly, also has a small amount of synthesis post insulator, and the former weight is large, and contamination resistance is poor; Although the latter's contamination resistance is strong, but because stem stem is epoxy glass material, rigidity is poor, upper end once it is subject to mechanical impetus, can deviation be produced---cause equipment normally to connect, the utility model porcelain composite post insulator, two large advantages of ceramic stem high for high mechanical shock intensity and the strong silicon rubber of hydrophobicity are melted one, both maintained the shock resistance of post insulator, anti-metachromia can also improve greatly, can realize non-maintaining.
Utility model content
The purpose of this utility model is the technical problem that the post insulator for solving existing application exists, there is provided a kind of large creepage distance, contamination resistance is good, and resistance to mechanical impact capacity is strong, anti overvoltage performance is high, can realize porcelain composite post insulator non-maintaining in operation of power networks.
Technical problem of the present utility model solves like this, construct a kind of porcelain composite post insulator, it is characterized in that having gold utensil, cement glue, ceramic stem, coupling agent layer, the silicone rubber jacket of band full skirt and the ceramic core shell of column region of non-composite silicone rubber is formed; Cement glue by gold utensil and ceramic stem good bond integral, silicone rubber jacket with full skirt is compounded in cast solid above the appearance of ceramic stem by coupling agent layer, ceramic stem has non-composite silicone rubber region, ceramic stem non-composite silicone rubber section region be ceramic stem range estimation region, aim at tour personnel estimate ceramic core two ends whether intact and arrange.
According to porcelain composite post insulator described in the utility model, it is characterized in that: in the upper end of ceramic stem or lower end, there is non-composite silicone rubber region; Or the upper and lower end of ceramic stem all has non-composite silicone rubber region.
The utility model has the advantage of: porcelain composite post insulator described in the utility model, more ceramic (glass) post insulator is lightweight, and self-cleaning ability is strong, can realize non-maintaining in operation of power networks, reduces the operating cost of electrical network, safe and reliable.Compare with synthesis post insulator, it maintains the advantage that ceramic resistance to mechanical impact capacity is strong, ensure that the accurate operation of transformer station's disconnecting link.The utility model can be widely used in, in 35kV ~ 1000kV alternating current-direct current transformer station, having good economic benefit and social benefit.In addition, due to porcelain composite post insulator upper end or lower end, or there is a bit of non-composite silicone rubber region at two ends up and down, are to make an inspection tour personnel for power equipment to provide the whether intact inspection area of porcelain core post.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the view of the corresponding 220kV of the utility model
Fig. 3 is the view of corresponding more than the 330kV of the utility model
In figure: 1. gold utensil, 2. ceramic stem, be 3. with the silicone rubber jacket of full skirt, 4. coupling agent layer, 5. cement glue, 6. the ceramic core shell of column region of non-composite silicone rubber.
Embodiment
Below in conjunction with accompanying drawing 1-3, the utility model is described in detail, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1, the utility model provides a kind of porcelain composite post insulator by improvement, has silicone rubber jacket 3, coupling agent layer 4, the cement glue 5 of gold utensil 1, ceramic stem 2, band full skirt; Cement glue by gold utensil and ceramic stem good bond integral, silicone rubber jacket with full skirt is compounded in cast solid above the appearance of ceramic stem at high temperature under high pressure by coupling agent layer, and in ceramic stem, non-composite silicone rubber section region is ceramics pole core range estimation region; During enforcement, the upper end of ceramic stem 2 or lower end have non-composite silicone rubber region 6; Or the upper and lower end of ceramic stem 2 all has non-composite silicone rubber region 6; Aim at tour personnel estimate ceramic core two ends whether intact and arrange.The utility model compares with existing transformer station pottery (glass) post insulator, lightweight, self-cleaning ability is strong, creepage distance is large, can realize non-maintaining in electrical network fortune, reduce the operating cost of electrical network, safe and reliable, 35kV to 1000kV transformer station can be widely used in, there is good economic benefit and social benefit.
The utility model porcelain composite post insulator, more ceramic (glass) post insulator is lightweight, self-cleaning ability is strong, safe and reliable, is the regeneration product of pottery (glass) post insulator, can be used in the power system transformer substation of electric pressures at different levels of 35kV to 1000kV.
In order to the technical indicator of satisfied different electric pressure, ensure the safe and reliable of its electrical network, be one section with Fig. 1 and be applicable to 35kV, 66kV and 110kV electric pressure, electric pressure raises then increases overlapping hop count, as: 220kV is increased to 2 sections, 330kV is increased to 3 sections, superhigh pressure and ultra high voltage, by its electric pressure, increase the overlapping hop count of n section post insulator, can reach the safety requirements of 1000kV voltage.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
