Glass reinforced plastic pipe is equipped with two sections, and glue impregnated paper capacitor core is placed in two sections of high compactness epoxy FRP pipes；The high compactness ring
Insulation filler is filled between oxygen glass reinforced plastic pipe and glue impregnated paper capacitor core；Every section of high compactness epoxy FRP pipes
External to adhere to silicon rubber umbrella skirt, both ends pass through ring with epoxy FRP pipes upper flange and epoxy FRP pipes lower flange respectively
The connection of oxygen mucilage binding；The intermediate sleeve flange is arranged between two sections of high compactness epoxy FRP pipes and glue impregnated paper capacitance core
Son is connect by epoxy glue load, and both ends are connect by bolt with epoxy FRP pipes lower flange；On the intermediate sleeve flange
Equipped with measurement terminal；The direct current-carrying of conducting rod is closely connect with air side connecting terminal.
The glue impregnated paper capacitor core is by electric insulation crimped paper and aluminium foil by pre-set programs size wound on electric conductor
Above, solidified by epoxide resin vacuum dipping.
The glue impregnated paper capacitor core is equipped with capacitance plate, and the capacitance plate is conductive material such as aluminium foil, or is semiconducting material
Such as semi-conductive tape.
The silicon rubber umbrella skirt is liquid silastic, or is firm silicone rubber.
The silicon rubber umbrella skirt and high compactness the epoxy FRP pipes sulfidization molding on epoxy FRP pipes, or individually
Silicon rubber umbrella skirt cover and be bonded in high compactness epoxy FRP pipes by epoxy glue.
The insulation filler is solid insulating material or insulating gas or liquid state insulating oil.
It is oil-free, without gas, pure solid, compact-sized, maintenance time the utility model has the advantages that structure of the invention is compact, easy to maintain
Number is less, and operation is more safe and reliable, avoids such product and explosion accident occurs when the failures such as insulation breakdown occur, greatly
Protect the safety of operating personnel.
