Product Description

Oil Immersed Inverted Current Transformers LVQB(T)-220W3/2X

Introduction:
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

0.5%.

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.

Note: 1 The Company reserves the right to change the parameters in the table.

2 When the parameters required by the customer are different from that in the table, they can be negotiated

according to the requirement of the customer.

3 There are several current ratios for one-time switch of the transformer.

4 We also can provide with products which meet the requirement of IEC and ANSI.
