At present oil-free dry sleeve pipe local discharging level is lower, and owing to the pole plate slippage that original structure easily produces, ruptures, causes electric performance failure of sleeve pipe or decline.
The purpose of this utility model provides a kind of dry type complex capacitance formula sleeve pipe, improves product partial discharge performance, improves mechanical stress and distributes, and improves the product bending property, stops the pole plate slippage, and is simple in structure, easy to use.
The technical solution of the utility model is: dry type complex capacitance formula sleeve pipe, it comprises that flange, capacitor core, conduit, insulating barrier, full skirt, measurement terminal connect and compose, it is characterized in that: fixedly be inlaid with the metal awl respectively at the conduit two ends of capacitor core, metal awl inclined-plane is rolled in the insulating barrier.
Described flange and capacitor core are fixed together by snap ring and nut.
Described flange outer surface is fixedly connected with the high frequency seat as measurement terminal.
There is coated semiconductor at described capacitor core pole plate two ends.
Characteristics of the present utility model are:
1, capacitor core adopts full-closed structure, can not be affected by the external environment, and fixedly is inlaid with the metal awl respectively at the conduit two ends of capacitor core, and metal awl inclined-plane is rolled in the insulating barrier.Stop the pole plate slippage
2, flange and capacitor core have adopted the novel structure that clamps, and improve stress distribution, improve the product bending resistance
3, insulator internal electrode pole plate has carried out anticorona processing, has improved product partial discharge performance
4, capacitor core and full skirt adopt injection moulding or bonding forming mode, eliminate effect of the interface, improve the product electric property
5, measurement terminal adopts High-frequency plug, and simplified structure improves performance, provides convenience to the user
6, hardness brass tube or copper tube are born the part mechanical stress simultaneously as the water conservancy diversion carrier catheter in the employing
7, install the metal awl additional at the conduit two ends, can fundamentally under manufacture process and running status, stop the pole plate sliding phenomenon of capacitor core, because teflin tape smooth surface, in manufacturing and running, and be vulnerable to abnormal external force effect, easily cause the slide relative between the insulating barrier, thereby influence arranging of capacitor plate, even the phenomenon of generation fracture, cause the electric performance failure of sleeve pipe, influence the normal transmission of electric power, install additional and make restraining force enhancing between the insulating barrier after metal is bored, stop relatively moving of insulating barrier.
8, spiral car coat type structure is adopted in the coupling part of flange end and capacitor core, improves mechanical stress
It is lower that this composite dry wall bushing has overcome present oil-free dry sleeve pipe local discharging level, and owing to the pole plate slippage that original structure easily produces, rupture, cause the shortcoming of electric performance failure of sleeve pipe or decline, external insulation adopts high-temperature silicon disulfide rubber, improves anti-filthy ability of this product and mechanical shock resistance.Interface adopts bonding way between external insulation and the interior insulation, eliminates the influence of interface to properties of product, strengthens the product operational reliability.
