SETFt 24 – 800 kVRIP Transformer Outdoor Bushing

RIP condenser bushing type SETFt

DesignThe insulating body of the RIP condenser bushing (RIP = Resin

Impregnated Paper) is made of special paper vacuum-impreg-

nated with epoxy resin. During the winding process, conductive

layers made of aluminum foil are inserted between the paper

for grading the electric field. Thanks to their good conductivity,

optimum voltage distribution is guaranteed even in case of

rapid voltage changes.

The insulating body is wound onto the winding support, impregnated

with resin and hardened. It receives its final shape by means of turning.

The RIP insulating body acts as an oil-tight seal to the transformer

in the flange. With a permanently installed current conductor, there

is no transformer oil above the flange, thus eliminating the possibility

of accidents with escaping oil and the consequent risk of fire.

The higher temperature class of RIP gives the bushings of this series

greater thermal reserves. Since it is not oil-filled, there are no tech-

nological constraints with regard to the installation position.

The standard bushing is designed for installation in a position 0 – 30°

from the vertical in accordance with IEC 60137. Other installation

situations are available on request.

The external insulation consists of a composite insulator with silicone

sheds. These are vulcanized on the mechanical support, a high-quality

wound insulating tube made of epoxy resins with glass fiber laminate

structure. This gives the housing not only its high mechanical strength

but also flexibility. The silicone shed insulation endows the bushing

with excellent dirt-repellent characteristics thanks to its hydrophobic

surface and the property of hydrophobic transfer in contamination

layers.

Generally, an alternating shed profile is provided so that the

bushings can also be used in a heavily contaminated environment.

The composite housings are provided at both ends with aluminum

fittings using a special joining technique to ensure a permanent,

gas-tight connection.

The gap between composite insulator and insulating body is filled

with a dry filling of polyurethane elastomer. This ensures a bushing

of absolutely dry construction. By using a special gas foaming process,

a fine-celled elastomer structure is obtained offering an outstanding

combination of permanently elastic yet mechanically strong proper-

ties and high electrical strength. The mechanical bond gives the

bushing a high degree of elasticity combined with good damping

characteristics. As a result, bushings of this type are particularly well

suited for use with extreme mechanical stresses, such as seismic

stresses.

Other advantages of the SETFt bushing:

■ Damage due to incorrect handling or vandalism are avoided

thanks to its impact strength and shock resistance

■ The lower weight of the bushing with composite insulator

simplifies handling and reduces stressing of the transformer

due to its low net mass

■ No dangerous fragments if the housing is damaged by internal

or external factors, no damage to adjacent parts of the substation

and risk to personnel in case of a fault reduced to a minimum

■ Use at very low ambient temperatures

■ Flame-resistant properties

■ Long operational experience: over 40 years

Head and flange consist of a weather-resistant aluminum alloy.

All seals are also designed as O-rings in self-contained chambers

and are made of temperature-resistant elastomers.

All bushings have a test tap. When the cap is screwed in position,

the last layer of the condenser grading is earthed via the contact

spring located in the cap. The built-in, insulated bushing has a

4-mm pin onto which a corresponding, resilient socket can be

plugged for test purposes. All bushings also have two M12 earthing

holes and threaded lifting holes around the flange pitch circle

diameter as standard. Provision is made for transformer venting.

The bushing can be transported and stored in any position.

All bushings are designed to comply with IEC Standard 60137

and tested accordingly. Bushings that comply with IEEE Standard

or other national regulations are available on request.

RIP condenser bushing type SETFt

Connection systemsThe SETFt series offers a large number of different connection options.

A clamping piece is mounted on the top end of the bushing head with

which the conductor or draw lead bolt is fixed in position. A releasable

transverse pin prevents it slipping into the transformer when working

on the clamping device and it also acts as protection against twisting.

Double seals are provided for sealing the bolts. A thin layer of insulation

must be wrapped round the conductor bolt in order to prevent contact

with the central tube of the bushing.

The clamping piece and all screw connections on the entire bushing

are corrosion-resistant. Venting of the central tube is located at the side

under the flange of the clamping piece and can thus be operated

independently of the conductor bolt.

In addition to the draw lead bolt mentioned, it is also possible

to provide a through conductor bolt, for example in case of higher

current requirements. Conductor bolts of this kind are insulated

with respect to the inner wall of the central tube with spacers.

Through conductor bolts can be supplied with a joint, preferably at flange

height or as requested by the customer. In order to be able to pull

the bolt through the central tube, a threaded hole is provided at the front

for screwing in an eyebolt or rod.

Customized modificationsThe types specified in this brochure represent standard versions.

Modifications are possible but may result in price changes or different

delivery times and must therefore be specifically requested.

The technical designs of these bushing types are documented

in comprehensive delivery specifications.

Screen electrodesBushings of the type shown in the illustration “Outlet end at the

transformer – with metal plate” must be shielded with an electrode.

The dimensions given in the table above refer to electrodes (EK1 ... EK4)

made of insulating material that can be detached via a bayonet

connection. They can be moved upwards as well as downwards,

and thus allow possible installation of a junction point for the current

conductor.

Bushings of the type shown in the illustration “Outlet end at the

transformer – without metal plate” in the voltage ranges 24 kV

to 170 kV (Um) require no additional shielding. However, with all

bushings of the type shown in the illustration “Outlet end at the

transformer – without metal plate” the gap between the outlet wall

(Ø d2) and the insulated conductor should be about 3 mm, e.g.

by applying corresponding insulation.

The required distance to ground “A” in each case is contained

in the table above. Additional insulating measures or larger distances

may be necessary because of the constraints when installing in the

transformer. The bushing can also be operated with electrodes

and barrier systems not manufactured by HSP. The distance must not

be less than the “Minimum distance A” given in the above table.
