DYSRM16-12 inflatable (totally enclosed) ring main unit

Ⅰ.Overview

Dysrm16-12 inflatable SF6 metal enclosed full insulation series ring network switchgear has been listed as a high-tech product in Zhejiang Province through the type test of the national high voltage apparatus test center and the high-tech project of Zhejiang Province. Widely used in 10kV / 6K power distribution system, it is the preferred switch product for power transformation and distribution systems of various users in urban and rural areas.

The switch cabinet is modular unit mode, which can be combined according to different purposes; It consists of fixed unit combination and expandable unit to meet the needs of various substations for flexible use of compact switchgear. Dysrim16-12 inflatable switchgear is a completely sealed system, and all live parts and switches are enclosed in a stainless steel shell. The whole switchgear is not affected by external environmental conditions, which can ensure operation reliability and personal safety, and realize maintenance free. By selecting expandable bus, any combination can be realized to achieve full modularization. The expansion bus is safely insulated and shielded to ensure high reliability and safety. Dysrm16-12 inflatable switchgear can also provide TV automation solution, form the concept of intelligent switch, and minimize the workload of on-site installation and commissioning.

DYSRM16-12 inflatable switchgear is divided into non expandable standard configuration and expandable standard configuration. Because of the combination of full module and half module and its own scalability, it has extremely special flexibility.

Dysrm16-12 inflatable switch complies with GB standard. The design life for operation under indoor conditions (40 ℃) and outdoor conditions (- 50 ℃) is more than 30 years.
