JLS-6、10、35 High voltage electrical energymeasuring box
This type of electrical energy metering box is designed for use in outdoor 10 kV, 50 Hz AC power systems for the metering of active and reactive energy. The product's performance complies with the requirements of standards GB17201, GB1207, and GB1208. This product primarily consists of two components: a combined instrument transformer unit and a watt-hour meter box. The combined instrument transformer unit comprises two single-phase voltage transformers and two current transformers. It utilizes No. 25 transformer oil as the insulating medium, and both the primary and secondary terminals are mounted on the front panel using porcelain bushings. The watt-hour meter box is mounted on the side of the combined instrument transformer unit and houses one active energy meter and one reactive energy meter.
Description JLS-6 / JLS-10 / JLS-35 High Voltage Electrical Energy Measuring Box is designed for power systems of 6kV, 10kV, and 35kV. It is used for accurate energy metering in medium-voltage networks by integrating current transformers (CT) and voltage transformers (VT) in a single metering unit. The product ensures reliable measurement performance and is widely used in power distribution and energy management systems.
Structural Features The metering box adopts an integrated CT and VT combination structure with a compact and sealed design, ensuring safe and stable operation. It features high measurement accuracy, strong insulation performance, and excellent resistance to environmental conditions such as moisture, dust, and temperature variations, making it suitable for long-term outdoor use.
Applications 1.6kV / 10kV / 35kV power distribution systems 2.Industrial and commercial energy metering 3.Substations and switchgear systems 4.Power grid monitoring and energy management 5.Outdoor metering and billing systems
