Oil-immersed paper insulation of current transformers

LVQB series current transformer has an inverted structure with SF6 gas insulation (Please see the figure). It is
connected in series with electric energy measurement, measuring, and relay protection functions.
Primary coil has a through-type conducting rod structure with good dynamic and thermal stability; its maximum
thermalcurrent can be up to 63kA/3s (when primary coil is connected in series).
Primary coil passes through the center of secondary coil without flux leakage. Measurement precision can be up
to 0.1 and 0.2S grades.
Secondary coil is fixed in an aluminum shielded-case by casting organic materials; measurement and protection
circuits cannot be damaged by insulation breakdown.
Optimal Electrode shielded structure improves internal and external field distribution of the product. It has an
excellent insulation property. Partial discharge test is carried out under power frequency test voltage.
There are two types of external insulation bushing for customers: they have excellent explosion-resistant and
shockresistant behaviors.
External bushing uses silicon rubber umbrella type apron reinforced by glass fiber. Optimal external surface
field makes silicon rubber avoid electrical erosion.
Porcelain bushing shell with high-strength.
Secondary outlet box is a complete structure by casting the aluminum alloy; its sealing structure meets the
requirement of IP55, which is dust proof, water proof and air permeable; secondary terminal for wiring uses
Phoenix special terminal; it is more convenient for operations such as plug-in, pull-out and wiring etc.
Seal ring is made of imported fluorocarbon silicone rubber, it is suitable for using in the area where there is
great temperature change or the environmental temperature is extreme. The leakage rate per year is less than
Product performance keeps changeless after severe transporting test.
Use an aluminum alloy cast case, all components including the base, connection box, stainless steel expander,
and nameplate etc do not rust forever.
A density meter is installed on the base, this meter can show the gas pressure and density in the transformer
(The show value is turned to be the internal gas pressure at 20 automatically). A signal for refilling gas is sent
out when the pressure in the transformer drops down to the alarm pressure.
