OMA-36(JLSZXW8-36)

1.General parameters:

2.Function and application:

Overhead pole mounted primary metering unit comply with the latest applicable industry standards and local and/or national electrical regulations (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 to reduce losses.

3.Main features

3.1The medium voltage transformer of the metering unit is composed of 3 single-phase combined transformers, which saves installation space. There is a meter box under the installation base. The high and low voltage integrated anti-stealing design can be installed directly and convenientlyon the pole outdoors.

3.2 The metering unit is equipped with a meter box and connected to the transformer connection. The meter and communication module installation space are reserved in the box, and the meter box door switch, proximity sensor, data debugging port, conversion switch, and door lock seal structure are reserved. To prevent electricity theft .

3.3 The meter box body is made of corrosion-resistant alloy aluminum or low-carbon steel hot-dip galvanized, and the sealing design is weatherproof, acid and alkali corrosion resistant, and UV resistant.

3.4 The medium voltage combined transformer is insulated with epoxy resin solid encapsulation, the surface is dirt-resistant, UV-resistant, has excellent dielectric and mechanical properties, no oil, no gas, and maintenance free, meeting the requirements of safe operation and environmental protection

3.5 The CT of the medium voltage combined transformer can be configured double transformation ratios, and it is convenient to set the conversion switch to change the transformation ratio. 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 is connected with NEMA contact strips and wiring clamps. The wiring terminals of the corresponding area can be configured according to requirements, and lightning arresters can be selected as required.
