1200A 17.5kV Pole Mounted Metering Unit JLSZXW8-17.5 3VT

OMA-17.5 (JLSZXW8-17.5)

Overhead pole mounted primary metering unit

1. PRODUCT INTRODUCTION

1.1 Product type name and model:17.5kV Overhead pole mounted primary metering unit, JLSZXW8-17.5 Combined Transformer

1.2 INTRODUCTION

This type metering box for outdoor dry-type three-phase primary metering unit, combined by three single phase transformers medium voltage measuring transformer assembly, each combination of single-phase combined CT&VT contains 1 set of CT coil and 1 set of VT coil, adopting alicyclic epoxy resin (CEP) vacuum pouring solid encapsulation, Cyclic epoxy resin (CEP) vacuum casting solid encapsulation, with excellent insulation performance and hydrophobicity, the surface is resistant to acid and alkali corrosion, pollution, and UV. It’s suitable for outdoor overhead line is connected to the public power system installation. The meter box is equipped with a meter box under the installation base of the metering box. The high and low voltage integrated anti-theft design is fast and easy to install. It is suitable for electrical energy metering, current and voltage measurement in urban and rural power distribution network lines with a maximum voltage of 17.5kV and below.

1.3 General parameters

1. The 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.

2. Main features:

1.1 The 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

1.2 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

1.3 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

1.4 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

1.5 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

1.6 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
