2.Product Function and Use
Overhead
pole mounted primary metering unit complies with the latest applicable
industrial standards and local and or national electrical code (such as IEC,
IEEE (ANSI), CAN, GOST, CEF). 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 so as to reduce losses.
3. Product Features
1. The whole
metering unit is designed with a metal box encapsulated as a whole. Inside the
box, there is a dry-type transformer pre-installed and a meter box
pre-equipped. It is with high and low
voltage integrated anti-theft design, can be installed directly on the pole
outdoors, which is convenient and time saving.
2. The
metering unit can be equipped with a meter box as required and connected with
the transformer interface. The meter installation space is reserved in the box,
the alarm signal of the meter box door switch sensor is reserved, and the door
lock seal structure is designed to prevent electricity theft.
3. The box is
made of corrosion-resistant stainless steel or equivalent performance
low-carbon steel with protective coating. The sealing design is weatherproof,
acid and alkali corrosion resistant, and UV resistant
4. The medium
voltage transformer is insulated with epoxy resin solid encapsulation and has
excellent dielectric and mechanical performance. It is oil-free, gas-free and
maintenance-free, meeting the requirements of safe operation and environmental
protection.
5. The CT of
the medium voltage combined transformer can be configured according to double
transformation ratios, and the VT is equipped with anti-short circuit and
overload protection devices as required to avoid burning and explosion caused
by VT short circuit and overload.
6. The primary end is made of silicone rubber composite
bushing, and the terminal block of the corresponding area can be configured
according to the user's requirements, and the lightning arrester can be
optional.
