The high-voltage metering box is a device used for the measurement of high-voltage electrical energy, particularly suitable for users of medium- and small-sized transformers. It can accurately and comprehensively measure active and reactive electrical energy. The product design is ingenious and rational, the structure is compact, aesthetically pleasing, and all parts are well-sealed, making it highly resistant to theft of electrical energy.
High-voltage metering boxes are typically composed of voltage transformers and current transformers, and are categorized into three-phase three-wire metering boxes and three-phase four-wire metering boxes. A three-phase three-wire meter box consists of two single-phase voltage and current transformers, while a three-phase four-wire meter box comprises three single-phase voltage and current transformer units. These transformers are housed within the box, with both primary and secondary output lines fitted with porcelain insulating sleeves on the panel. An electric meter is mounted on the outer surface for metering purposes.
In addition, high-voltage metering boxes have the following characteristics:
1 High precision: capable of accurately measuring active and reactive power in high-voltage transmission lines, making it suitable for applications requiring precise measurement of electrical energy consumption.
2 Lightweight: Compared to traditional oil-immersed metering boxes, it is lighter in weight, making it easier to install and transport.
3 Easy installation: The design of the structure is rational, and special tools and skills are not required for installation. It can be conveniently installed on existing high-voltage transmission lines.
4 Strong anti-theft capabilities: The casing is tightly sealed, making it difficult to be tampered with, thereby effectively preventing instances of theft.
5. The configuration of the instrument box forms a complete metering device: The high-voltage metering box can be used in conjunction with the instrument box to create a complete electrical energy metering system, facilitating management and monitoring.
In summary, high-voltage metering boxes are precise devices for measuring electrical energy, suitable for a wide range of applications involving high-voltage electrical energy measurement.
