Combined transformer/metering tank

The combined transformer/metering tank is one kind of outdoor power measuring device.

Description

The combined transformer/metering tank is one kind of outdoor power measuring device,which is composed of two sets single-phase wholly insulated voltage transformers,forming three-phase V/V wiring,and two current transformers are separately series connected to A and C phase.

This product is applied to certain outdoor circuit 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.

Construction

The metering tank is composed of two single-phase current transformers(PT) and two current transformers(CT),of which the PT and CT both are electromagnetic type,and fixed onto pole-plate of oil tank,whole the oil-tank cover is joined.It could lift oil tank by means of using two flying rings on oil-tank cover,the oil tank owns quadrate appearance,there are oil-meter indicator,grounding bolt and fuel outlet valve installed at side of oil tank.
