An appropriate number of oil injection branch pipes enter the oil injection tank through flanges.
Each group of branch pipes can be connected to the product through appropriate pipelines to facilitate qualified insulating oil to enter the product.
The oil injection system is equipped with a turbine flow meter, which is used to preset the total oil injection amount of each branch. When the preset oil injection amount is reached, the oil inlet valve closes.
Each branch is also equipped with a manual stainless steel control valve to control the oil injection flow, thereby controlling the oil injection speed.
The high-end control system uses Siemens PLC as the main control unit, and the operating system can realize automatic control of vacuuming and oil filling during the process.
Including temperature overheating alarm prompts, automatic gas cutoff protection, alarm prompts, etc.
The equipment is a single door with vacuum and oil filling functions, and the maximum weight can reach 30T in one operation.
Under vacuum conditions, a single oil filling valve can be used to achieve automatic quantitative oil filling or manual oil filling.
The operation of the equipment is controlled by buttons on the control panel, including door switches, vacuuming, manual/automatic oil filling, etc., and is equipped with complete safety protection devices.
