Overview:
Since the 1950s, the development of medium-voltage switchgear has gone through the stages of open type, box type, metal enclosed type, etc. There is no problem in meeting the functional use requirements of the equipment, and the products have long been serialized and fully covered. Small size, maintenance-free, highly modular, safe and reliable environmentally friendly gas-insulated ring network switchgear has developed rapidly. It can realize remote monitoring, control and management of the power system distribution network, realize the needs of power grid optimization, power safety, power management, energy saving and consumption reduction: the system can also be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas and commercial office buildings.
DSY-CV-12/T630-20 environmentally friendly gas-insulated ring network switchgear fully introduces advanced production equipment and manufacturing technology to realize localized production, greatly reduce manufacturing costs, shorten delivery cycles, and is well received by users after its launch.
Product Features
-
Complex and integrated products
The inflatable shell of the switchgear is made of high-quality 2.5mm thick stainless steel plate through laser welding, which ensures the airtight reliability of the gas box, high mechanical strength, good corrosion resistance, and the protection level of the inflatable shell reaches IP67: the gas box is equipped with an explosion-proof diaphragm, which can effectively prevent damage to people and equipment caused by excessive air pressure: all conductive parts are enclosed in the gas box, which can not only avoid the influence of external environmental factors, but also improve the operating reliability, making it maintenance-free (or less maintenance) and meeting the requirements of miniaturization.
The main circuit adopts a combination of a three-position switch (connection + isolation + grounding) and a vacuum interrupter. This structure is the most mature configuration method at present, and is particularly suitable for the current power grid operation and maintenance needs. -
Environmental and pollution-free
The insulating medium of the DSY-CV-12/T630-20 environmentally friendly gas-insulated ring network switchgear is zero-grade dry air (purchased from outside) or 99.99% pure N2 in accordance with GB/T8979-2008. Gas leakage will not cause any impact on the external environment, and no recycling treatment is required.
-
Perfect mechanical interlocking
The operation panel of DSY-CV-12/T630-20 environmentally friendly gas-insulated ring network switchgear has perfect five-protection mechanical interlocking function, and all interlocking functions are configured internally. Please follow the operation instructions for operation, which is very convenient to use.
