outdoor oil immersed combined transformer

High voltage power metering box (without the combined transformer of the electricity meter) AC oil immersed outdoor type (also suitable for indoor), is a direct measurement of active and reactive energy measurement equipment in high voltage lines.Suitable for rated frequency 50Hz, 60Hz three-phase AC 10kV, 6kV power system network. It has the advantages of high precision, light weight, easy installation and anti-theft.It is welcomed by the majority of power supply departments and plays a major role in preventing electricity theft, saving energy and strengthening power supply management.

General:

This product is mainly composed of two parts of the combined transformer and the meter box, the combined transformer is composed of two synthesis of 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. The high-voltage electric energy metering box is used for high-voltage metering in AC 50Hz, 10KV three-phase lines. It is composed of current transformer, voltage transformer and box for installing current transformer, voltage transformer and energy meter. It is mainly used for the measurement of active and reactive electric energy.
