NSRM gas insulated enclosed metal switchgear products are widely used in 10-35kV distribution systems and are the preferred switch products for various urban and rural users' power transformation and distribution systems.

The switchgear adopts a modular unit mode, which can be combined according to different purposes; There are two main types of fixed unit combinations and expandable units, which meet the flexible use needs of various substations for compact switchgear.

NSRM gas insulated enclosed metal switchgear is a completely sealed system, with its charged components and switches enclosed within a stainless steel body. The entire switch device is not affected by external environmental conditions, ensuring operational reliability and personal safety. And it has achieved maintenance free operation. By selecting expandable busbars, any combination can be achieved to achieve full modularity. The expansion of busbar safety insulation and shielding ensures reliability and safety.

NSRM gas insulated enclosed metal switchgear can also provide TV based automation solutions, forming the concept of intelligent switches and minimizing on-site installation and commissioning workload.

NSRM gas insulated enclosed metal switchgear is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full and half modules and self scalability, it has extremely special flexibility.

NSRM gas insulated enclosed metal switchgear complies with GB standards. The design lifespan for operation under indoor conditions (20 ° C) exceeds 30 years.

Feature:

1. Technical description

The NSRM gas insulated enclosed metal switchgear is installed on a galvanized sheet frame, with the switch unit inside an SF6 gas box made of corrosion-resistant and non-magnetic 3mm thick stainless steel plate. SF6 gas tank is a "sealed pressure system" that can operate for 30 years under normal working conditions. The pressure of SF6 gas during normal operation is 0.15-0.4 bar. The gas box is equipped with a pressure release device to ensure that gas can be released from the bottom or rear when the pressure is too high.

2. Switching unit

The load switch adopts a coaxial rotating double break method, which cooperates with the sliding plate through the same operating hole for kinetic operation. Therefore, the switch can only be in one of the three states of "closing, opening, and grounding" at any time, completely avoiding misoperation.

3. Operating mechanism

The operating mechanism of the switch is installed at the front of the air box and has undergone special processing to prevent rust and corrosion. It is convenient for manual operation and maintenance and easy to achieve electric operatio
