Structure feature
The product mainly consists of combined instrument transformer and watt-hour meter. The combined transformer is equipped with 2 or 3 single phase VT and CT units.The transformer is insulated in 25# transformer oil. The outlet terminals of primary and secondary windings are encapsulated in porcelain bushing and fixed on the panel.Watt-hour meter tank is fixed on the flank of combined instrument transformer and comprises one active watt-hour meter and reactive watt-hour meter. The products are reliable, accurate, light and convenient in installation. They are also designed against stealing electricity.
1 - The transformer equipped with primary and secondary winding. The windings are fixed to the iron core bar by casting.
2 - For the two secondary windings, the first one is for either measuring or protection purpose; the other is for being connected into an open-delta connection in a 3 phase system.
3 - The outlet of the primary winding is insulated from the earth to a correspondent level.
4 - The secondary terminal board is covered with a transparent cover made of plastic.
5 - The bolted earthed clamp is located on the transformer base plate.
6 - The transformer is fixed onto the base plate by four screws.
