Product Detail

Overview

NG7-40.5 series SF6 gas-insulated switchgear is a new generation of miniaturized products designed and manufactured by IEC 62271-200.

It has a variety of combinations and can be flexibly extended, which not only meets the requirements of power distribution, but also meets the needs of various secondary distribution application for flexible compact switchgear. It is widely used in public power grids, utilities, rail transit, new energy E-house, solar farm, wind farm, data center and other new energy fields.

The NG7 series switchgear employs a full-seal structure scheme and modular design. All live parts are placed in the sealed shell, which makes them free from the impact of external environment and ensures the requirements of high reliability and security. Additionally, automation solutions can be configured to realize intelligent control.

What are the basic knowledge points about transformer bushings?
1. Functions of Transformer BushingsThe core function of transformer bushings is to lead the coil leads out to the external environment. They serve both as insulating components between the leads and the oil tank and as fixing devices for the leads.During the operation of a transformer, bushings continuously carry load currents and, in the event of an external short circuit, withstand short-circuit currents. Therefore, transformer bushings must meet the following requirements:Possess specified e

Development Direction of Intelligent Monitoring for Surge Arresters in the Internet of Things Era
1. Current Status and Shortcomings of Online MonitorsCurrently, online monitors are the most commonly used tools for surge arrester monitoring. While they can detect potential defects, they have significant limitations: manual on - site data recording is required, precluding real - time monitoring; and post - collection data analysis adds to operational complexity. IoT - based intelligent monitoring overcomes these issues—collected data is uploaded via the IoT to processing platforms, and
