Lb7-220 Oil-Immersed Fully-Sealed Structure Current Transformer

Introduction to Product:

This product has an oil-immersed fully-sealed structure. It consists of metal expander, oil conservator, main

body and other accessories. The primary coil is U-shape, the main insulation uses capacitor type oilpaper, use

the high voltage cable paper to wrap the core of primary coil, and set up several main shields among it.

The secondary coil is set up at the lower part of primary coil; the whole main body is fixed in the oil tank. There

is a bushing at upper part of oil tank, and an oil conservator is set up on top of bushing, the primary wire is lead

out via the hole of oil conservator, the seriesparallel switching operation is carried out outside the oil

conservator.

Use a stainless steel expander as the oil compensation device to ensure oil quality. Oil level is indicated by the

pointer at the upper window of expander.

A nameplate showing the technical data and a description plate showing the coils arrangement schematic

diagram are set up on the oil tank. There are four holes or lifting blocks on the under-frame for hoisting the

product, and an oil-discharge valve  and earthing bolts at bottom of oil tank.

The product can have five or six secondary coils, the secondary measurement coil is made by microcrystalline

alloy with high magnetic conductivity, thus can ensure that the measurement precision reaches up to 0.2 grade

or 0.2S grade.

The secondary terminal has limit and double sealing functions. The outlet box is made by stretching wholly; it is

elaborate and practical. The oil tank is carried out surface treatment; it is bright and durable.

Complete transformer is fully sealed. New technology and new materials such as hot galvanizing or stainless

steel standard parts etc are used for outside of the product to prevent from rustless and get long working life.

Reasonable and originative structure as well as advanced technology ensures that the product runs reliably,

safely and durably.
