The JLSGK-12 (7.2) prepaid high voltage meter box is a state-of-the-art integrated solution for high-voltage metering and load control in three-phase power systems. Exclusively designed for outdoor installation, this robust device combines advanced metering technology with industry-leading safety features to meet the evolving demands of modern power distribution networks. By integrating essential components into a single compact unit, it simplifies installation, reduces wiring complexity, and delivers accurate energy measurement with enhanced load management capabilities. Its durable construction ensures reliable performance in the harshest environmental conditions, making it the ideal choice for power utilities and commercial users seeking efficient, secure, and cost-effective energy management solutions.
Engineered to withstand extreme environmental conditions, the outdoor high voltage metering box operates flawlessly across a wide temperature range and altitude tolerance. Its weather-resistant enclosure provides superior protection against dust, rain, snow, and UV radiation, ensuring consistent performance in both urban and rural locations. This rugged design minimizes maintenance requirements and extends service life, even in the most challenging climates.
The three-phase high voltage meter box integrates all essential components into a single unit, including a high-voltage vacuum circuit breaker, current transformer, voltage transformer, and control meter box. This innovative integrated design eliminates the need for separate components and complex wiring, significantly reducing installation time and costs. The voltage transformer features a special winding that powers the switch's opening and closing mechanism, eliminating the requirement for external power sources.
Adopting a reliable V-V wiring method for the voltage transformer, the device ensures accurate voltage measurement and stable system performance. The current transformer can be configured with a double ratio structure, allowing it to adapt to different load conditions and enhancing its versatility across various applications. This flexible configuration makes it compatible with most standard three-phase high-voltage power systems.
Addressing critical security concerns, the anti-theft high voltage meter features a unique design that separates the meter control box from the combination switch. All internal wiring uses metal armored cable, which is highly resistant to tampering and theft. This comprehensive security system protects valuable equipment and ensures the integrity of energy measurement data, preventing revenue loss for power utilities.
