NYS-12 Solid-Insulated Ring Main Unit Switchgear from China Suppliers - Eco-Friendly Factory Solutions for Power Distribution
Overview
NYS-12 solid insulated ring network switchgear is a new generation of environmentally friendly composite insulation ring network cabinet developed by our company. It is a fully sealed power supply unit with all live parts. The components and switches are fully sealed in an epoxy plastic shell, and there is no SF6 gas in the shell. The entire switch device is not affected by the external environment, ensuring operational reliability and personal safety, and is maintenance-free.
The solid insulation ring network cabinet consists of three types of switches, namely V unit (circuit breaker unit), C unit (load switch unit), and F unit (combination electrical unit). Each unit can be used alone or expanded freely. Its structure is divided into an intelligent control instrument room, an operating mechanism, and a primary part.
Intelligent Control
The instrument room can be equipped with a microcomputer protection (controller) for advanced power grid management.
APG Gel Process
The primary part completely seals the disconnector and the arc extinguishing chamber in epoxy resin with a special busbar connector.
Advanced Arc Chamber
Employs copper-chromium contact material, R-type longitudinal magnetic field contact, and complete one-time sealing process.
Compared with previous systems (which utilized copper-aluminum contact material, cup-shaped longitudinal magnetic field contact structures, and incomplete one-time sealing processes), the short-circuit current breaking capacity, stability, electrical life, temperature rise, and insulation level of this arc extinguishing chamber are significantly improved.
The operating mechanism adopts a spring-operated mechanism integrated with the switch, meaning the spring-operated mechanism of the isolating switch and the main switch is integrated. This design easily realizes interlocking, uses fewer parts, reduces unnecessary transmission links, provides high reliability, and can realize electric operation according to user needs.
