Intelligent High Voltage Switch

Product Overview

Intelligent high-voltage switch is a new type of high-voltage electrical equipment with independent intellectual property rights, integrating high-voltage switch with various functional modules. In addition to all the functions of the original high-voltage switch, it has increased the functions of bidirectional metering, prepayment, freezing of data, event logging, fault localization, and open connection with the main station. It is adapted to the large-scale construction and transformation of distribution networks, and is the preferred product for the lean management of distribution lines.

Intellectual Property Rights

"ZL201210084903.3 Embedded power metering method and extended application method for high-voltage electrical switchgear" is the core invention patent and 11 other subsidiary patents.

Product Features

1、Satisfy the distribution network simultaneous line loss management, realize "three remote".

2. Adopting new type voltage and current sensor sampling device to ensure the reliability of high-voltage data collection.

3、Measurement and measurement, protection signals are independent, do not interfere with each other, to meet the requirements of measurement certification and type test.

4, follow the industry-related measurement, protection, control and other protocol agreements and their filing documents.

5、Measurement error of the overall verification, than the traditional high-voltage energy metering device accuracy of two levels.
