Introduction for Structure
LB6-110 type current transformer has an oil-immersed fully sealed structure. The primary coil is U-shape, the
main body is fixed on the bracket, the main insulation uses capacitor type oilpaper, use the high voltage cable
paper to wrap the core of primary coil, and set up several capacitor shields among it, the internal shield is
connected to high potential, and the external shield is connected to ground reliably.
There is a porcelain bushing at the upper part of oil tank, and an oil conservator is set up on top of porcelain
bushing, primary outlet terminal is on the oil conservator, series-parallel connection uses an external switch
device, i.e., the 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 is set up on the oil tank to show the technical data. There are four lifting blocks for hoisting, an oil-
discharge valve and earthing bolts at the bottom of oil tank.
The product can have four to 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. 2 600A or above current transformer has a pigtail at measurement secondary coil, in order to
get two current ratios.
Use new technology and new materials such as hot galvanizing or stainless steel standard parts etc for outside
of the product to make complete equipment rustless.
Reasonable and originative structure as well as advanced technology ensures that the product runs reliably,
safely and durably.
Leading wire of secondary coil and leading wire of ground terminal of primary coil are connected with Phoenix
special terminal in the secondary terminal box via the terminal block cast as a whole with epoxy on the shell. It is
more convenient for operations such as plug-in, pull-out and wiring etc. The sealing performance meets the
requirement of IP55.
The transformer can be installed horizontally or vertically.
