2.Product function and use:
The Overhead pole mounted primary metering unit complies
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:
3.1. 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;
3.2. 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;
3.3. 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;
3.4. 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;
3.5. 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.
3.6. 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.
