SSR-12 Environment protection gas insulatedring network switchgear
★Circuit breaker mechanism
The precision transmission mechanism with reclosing function is connected by V-shaped key. The shaft support of the transmission system adopts a large number of rolling bearing design schemes, which are flexible in rotation and high in transmission efficiency, so as to ensure the mechanical life of the product more than 10000 times. The electrical components are pre designed and can be installed and maintained at any time.
★Isolation mechanism
Single spring double operating shaft design, built-in reliable closing, opening, grounding limit interlock device, ensure that closing and opening have no obvious overshoot. The mechanical life of the product is more than 10000 times, and the electrical components are pre designed, which can be installed and maintained at any time.
★Arc extinguishing device/disconnector
The closing and opening device with cam structure is adopted, and the dimension of over stroke and full stroke is accurate, and the production compatibility is strong. The insulation side plate adopts SMC molding process, with accurate size and high insulation strength. Three position design is adopted for closing, opening and grounding of disconnector, which is safe and reliable.

★Three position disconnector
The disconnector is designed with three positions to prevent misoperation. High performance disc spring ensures the stability of contact pressure and is conducive to the design of contact with closing shape, thus ensuring the reliability of grounding closing.
★Three position isolation mechanism
The three position isolation mechanism with quick closing function is designed with single spring and two independent operating shafts to avoid misoperation.
The core unit module can be sold separately, and all parameters have been adjusted in place before delivery, so customers do not need to debug again.
The customer only needs to install the core unit module in the cabinet for set completion.
Our company provides customers with a full range of cabinet drawings, secondary schematic diagrams, product manuals, promotional materials, technical consulting and other services for free.
