Product Description

Product Name:    110kV High Voltage Gas SF6 Insulation Head Type Design Current Transformers

 

1. Application:

Guangdong Sihui instrument current transformers are widely used in commercial, industrial and residential areas. They are for current measuring and protection, delivering high accuracy in current metering. Our current transformers are having a wide range, including epoxy resin medium voltage current transformers, epoxy resin Low voltage current transformers, oil immerged current transformers, dry-type high voltage current transformers and gas SF6 high voltage current transformers and so on.

 

2. Main Features

The current transformer is SF6 gas insulation, inverted frame, with the top of T type aluminium case which there are secondary winding(s) and primary winding(s) inside. The bushing is composite materials with silicon rubber umbrellas or high strength porcelain. The secondary terminal leads which through the metal tube are connected with the secondary terminals box which at the base. There is a pressure relief device at the top of the case, when the pressure is more than 0.8MPa if the current transformer is discharge inside, the relief device will be broken to release the pressure and send an alarm information. There is a SF6 density monitor fix at the base, it can indicate the SF6 pressure which inside the current transformer (its indicated value is the SF6 pressure at 20°C), and it will provide an information when the SF6 pressure is drop down to the minimum  service pressure of the current transformer, to remind the user replenish the SF6 gas to the rated pressure.

 

3. Manufacturing Standard:  IEC 61869-2:2012, GB20840.2.
