Main features of the product
◇Technical description
The SDTKR-12SF6 gas-insulated high-voltage AC metal-enclosed switchgear is installed on a galvanized sheet frame. The switch unit is in the SF6 gas tank, which is made of corrosion-resistant and non-magnetic 3mm thick stainless steel plate.
The SF6 gas tank is a "sealed pressure system" that can operate for 30 years under normal working conditions. The pressure of SF6 gas is 0.15~0.4bar during normal operation. The gas tank is equipped with a pressure release device to ensure that the gas can be released from the bottom or rear when the pressure is too high.
◇Switch unit
The load switch adopts a coaxial rotating double breakpoint method, and kinetic energy operation is performed through the same operating hole and the slide plate. Therefore, the switch can only be in one of the three states of "closing, opening, and grounding" at any time, completely avoiding misoperation.
◇Operating mechanism
The operating mechanism of the switch is installed on the front outside the gas tank. It is treated with special technology to prevent rust, facilitate manual operation and maintenance, and is easy to achieve electric operation.
