1. Product introduction:
1.1 Product name and model:24kV Pad mounted primary metering cabinet PMY9-24, JLSZXW9-24 combined transformer
1.2 Product overview:
The metering cabinet is for outdoor cabinet type one-piece three-phase primary metering unit , inside has assembled a combination of three independent voltage transformer and current transformer, voltage transformers are made up of three-phase Y-Y star connection, current transformers can be 2pcs or 3pcs optional configuration, cabinet adopts zinc steel, stainless steel or aluminum alloy etc, cabinet surface spraying protection layer resistant to acid and alkali corrosion , prevent the UV irradiation, suitable for outdoor underground cable connected to the public power system. The metering cabinet has installed complete measuring meter box or interval, instrument transformers’ secondary lead all converge in meter box, equipped with test terminal blocks and electric meter installation space, can be configured as required when using electric meter or the user configuration of watt-hour meter can access, suitable for high voltage equipment in urban power distribution network line 24 kV and below for electric energy metering, current and voltage measurements.

1. The metering cabinet adopts the overall housing-shaped box design and is divided into three internal compartments, including medium-voltage cable connection room, medium-voltage instrument transformer room and metering meter box room. The compact and beautiful housing design does not affect the greening and landscape, and the outdoor floor installation is convenient and quick;
2. The metering unit shall assemble the instrument transformer and the meter box as a whole, preset the alarm signal of the door switch sensor, the lock seal and the ingenious door opening and closing linkage structure. Only after the medium-voltage cable room is opened, then anti-electricity-stealing design of meter box room can be opened.
3. The cabinet body is made of corrosion-resistant stainless steel or low carbon steel of the same performance. It is designed to be weather-proof, and the surface is coated with anticorrosive paint powder layer,acid and alkali resistance, UV resistance.
4. The internal MV combined instrument transformer is encapsulated and poured with epoxy resin solid, the surface is fully screened and touchable, and can be closely fitted with the external box. The compact size is only half that of the air insulation metering box, free of oil and gas and free of maintenance, meeting the requirements of safe operation and environmental protection;
5. The primary connection adopts separable sealing connection. The primary connection bushing have two connection types ( 200A bushing well insert+200A connector and 600A interface bushing+600A connector) according to standard IEEE STD 386.
