outdoor kilowatt-hour meter box oil-immersed type combined transformer

The combined transformer (another name is metering tank) is one kind of outdoor power measuring device. which is composed of two sets single-phase wholly insulated voltage transformers,forming three-phage V/V wiring. and two current lransformers are separately series connected toA and C phase. The JLS-35metering tank is one upgraded product based on old product of same kind. just adding moisture-proof device onto oil tank's cover,which could effectively prevent exteral humidity form entering into oil, so as to prolong service life of product, while, compared with old product.
its advantage contains targer capacity,smaller volumeand weight. simplifying installing.
This product is applied to certain outdoor ci rcuit of AC50-60Hz,rated volt being 35kV or lower, to be used for metering of current, voltage and electric energy etc, this product is suitable for rural outdoor transformer substation,miniature transformer station and substation of industrial
enterprise etc. Adding active and reactive energy meter onto combined transformer is named as high volt power metering tank.

General:

This product is mainly composed of two parts of the combined transformer and the meter box, the combined transformer is composed of two or three single-phase voltage transformer and current transformer, with 25# transformer oil as the insulating medium, the first and second outlet end are installed on the panel with porcelain bushing. The watt-hour meter box is mounted on the side of the combined transformer and consists of a watt-hour meter and a reactive watt-hour meter. It has the advantages of high measuring accuracy, light weight, convenient installation and anti-theft.
