Overhead Pole Mounted 12kV 1000A Primary Metering Unit 2CT

2. Product function and use:
Overhead pole mounted primary metering unit Comply with the latest applicable industry standards and local and/or national electrical regulations. It is used for three-phase overhead power grid energy measurement management and distribution network automation management system. The primary side measurement is more accurate, and the power loss of the line can be effectively measured to reduce losses.

3. Main features of the product:
1. The integrated solid package of the medium voltage combined transformer of the metering unit has a compact and beautiful design, eliminating the need for multiple single transformer combined installation and ring connection, and can be installed directly on the pole outdoors, which is convenient and quick;
2. The metering unit can be equipped with a meter box as required and connected to the transformer connection. The meter is installed in the box, and the meter box door switch sensor alarm signal is reserved. The door lock seal structure is designed to prevent electricity theft;
3. The meter box body is made of corrosion-resistant stainless steel or low-carbon steel of the same performance, and the sealing design is weather-proof, and the surface is coated with an anti-corrosion paint powder layer, which is resistant to acid and alkali corrosion and UV;
4. The medium voltage combination transformer is insulated with epoxy resin solid encapsulation, and the surface is dirt-resistant, UV resistant, and has excellent dielectric and mechanical properties. Compared with the dispersed single-phase combination transformer, its size is more compact, oil-free, gas-free Maintenance to meet the requirements of safe operation and environmental protection;
5. The CT of the medium voltage combined transformer can be configured with double transformation ratios, and it is convenient to set the changeover switch. The VT is equipped with anti-short circuit and overload protection design to avoid burning and explosion caused by VT short circuit and overload.
6. The primary connection adopts the contact bar and the terminal clamp connection. The terminal block of the corresponding area can be configured according to the user's requirements, the lightning arrester mounting bracket is reserved, and the lightning arrester can be configured at the primary end as required.
