Product Description

SF6 Gas-insulated Inverted Current Transformer

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

thermal current 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.

Seal ring is made of imported fluorocarbon silicone rubber, it is suitable for using in the area where there is

greattemperature 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, andnameplate 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 showvalue is turned to be the internal gas pressure at 20 automatically). A signal for refilling

gas is sent out when the pressurein the transformer drops down to the alarm pressure
