China's first sensor-type high-voltage energy meter runs well

Zibo meter insurance transformer research institute developed indoor, outdoor sensor-type high-voltage energy meter, after a few months of network operation, after several thunderstorms baptism of running status is good. The table utilizes non-traditional transformers as high-voltage current, voltage conversion equipment, voltage, current sampling with independent intellectual property rights of the VIV technology and penetrating sensing technology. Compared with the existing power measurement device has many advantages:

1. Energy-saving effect is obvious: cost-effective, the table with the existing high-voltage energy metering devices compared to the amount of electricity saved every 5 years can be replaced by a product.

2. Improve the quality of power supply: due to the sensor-type high-voltage energy meter using non-traditional transformers instead of electromagnetic transformers, improve the existing electrical performance of the power measurement device, phase-to-phase to withstand the frequency voltage ability to enhance the device does not show inductive, do not participate in the resonance, anti-resonance ability, phase-to-phase frequency voltage of 28KV can be a long period of continuous operation.

3. Good measurement performance: high-voltage energy meter of high-voltage current, voltage conversion equipment and power measurement unit for the overall design, matching good measurement performance, wide load characteristics, before using the overall calibration of the product, accurate measurement, improve the impartiality of high-voltage energy measurement.

4. Save electricity investment: simple installation, space-saving, small size, light weight. Save copper, silicon steel sheet effect is remarkable.

5. Promote scientific and technological progress, adapt to power system automation: conducive to the promotion and application of non-traditional transformer high-voltage current and voltage conversion equipment. High-voltage energy meter to replace the current high-voltage energy measurement devices, high-voltage voltage, current conversion equipment and metering units to unify the overall design and manufacture, and promote scientific and technological progress in the electrical instrumentation industry.

August 21 Shandong Power Group Corporation, senior engineer, consultant of the National Standardization Technical Committee of Electrical Instrumentation, power industry, electrical measurement standardization of hormone committee consultant member Zhang Chunhui came to our company, a field visit to the network operation of the sensor-type high-voltage energy meter, high-voltage energy meter calibration site. And gave a high evaluation, on the sensor-type high-voltage energy meter and its traceability technology and our technical staff for discussion, at the same time for our future research and development of new products put forward guiding suggestions.
