Installation environment: it is installed in a place without fire, explosion hazard, serious pollution, chemical corrosion and violent vibration.
If the above conditions are exceeded, it can be negotiated with the company.
It has small volume and compact structure, and the floor area is only about 1 / 3-1 / 5 of the floor area of domestic European box transformer of the same capacity. It has a fully sealed and fully insulated structure without insulation distance, which is safe and reliable.
The transformer has excellent performance and adopts S11 transformer with low loss, low noise and strong overload capacity.
The product is divided into three parts: main voltage separation chamber, low-voltage chamber and transformer. It is generally arranged in "product" type and "target" type. It can realize high and low voltage measurement
The high-voltage side adopts V-type or T-type load switch and two-stage fuse protection, which can be used for both ring network and terminal, and the power supply mode is flexible and reliable.
The high voltage chamber is equipped with oil level gauge, pressure gauge, pressure relief valve, oil drain valve and other components to monitor the operation of the transformer. The high voltage incoming line adopts cable plug and can be equipped with zinc oxide arrester.
Meet various low-voltage feed out requirements, and add low-voltage metering, shunt outgoing line and capacitance compensation according to user requirements.
The transformer adopts corrugated fins for heat dissipation. After special process treatment, it has strong anti-corrosion ability. The shell can be made of cold wheel plate, stainless steel and other plates.
