LOW ENERGY-CONSUMING SERIES CURRENT TRANSFORMER FOR 1-1000 KV TRANSFORMER DETECT

摘要

A low energy-consuming series current transformer for 1-1000 KV transformer detect, which is a core through typed current transformer, includes an iron core (1), a primary coil (2), a secondary coil (3). It uses the high pressure of 10-1000 KV series insulating cable as primary bus bar. The secondary coil (3) connects to the current coil of an electric meter. The secondary coil (3) connects in series to an ammeter (5) and a voltmeter (4) that in parallel connection. One end of the ammeter (5) and the voltmeter (4) is connected with an end of the secondary coil (3) through an on-off switch (7). Another end of the ammeter (5) and the voltmeter (4) is connected with another end of the secondary coil (3) through a lead. The transformer is simple in structure, consumes low energy, is safe and reliable, and convenient to use.
