DESCRIPTION
Description
HXGN-12(FR) box type fixed AC metalclad ring main unit switchgear (referred to as "RMU cabinet"), is a new type of high voltage switchgear produced for urban power grid transformation and construction needs. In the power supply system is also used for breaking load current and short circuit current, suitable for AC 3-10KV, 50HZ distribution system. Widely used in urban power grid construction and transformation projects, industrial and mining enterprises, high-rise buildings and public facilities, as the ring network power supply unit and terminal equipment, plays the power distribution, control and protection of electrical equipment, can also be installed in the pre-installed substation. The ring cabinet is equipped with vacuum load switch and spring operated mechanism, which can be operated manually or electrically. Ground switch and isolation switch with hand knife operating mechanism, the ring network cabinet complete set of strong, small size, no combustion and explosion risk, with reliable "five prevention" function.
The ring main unit cabinet adheres to the GB3906-2006 "Alternating-current metal-enclosed switchgear and controlgear for rated voltages above 3.6 kV and up to and including 40.5 kV", IEC60420 "High-Voltage Alternating Current Switch-Fuse Combinations" standard of the relevant provisions.
