1. Performance and uses of power transformers:1. A step-up transformer can be used to increase the terminal voltage of the generator to tens of thousands or hundreds of thousands of volts to reduce the transmission current and reduce the energy loss on the transmission line without increasing the wi
Power transformer installation(1) Equipment and material preparationThe transformer should be equipped with a nameplate. The nameplate should indicate the name of the manufacturer, technical data such as rated capacity, primary and secondary rated capacity, primary and secondary rated voltage, curre
When dealing with transformer short-circuit accidents in daily operations, it is necessary to find out the essence of the problem through inspection and testing. When the transformer suffers a sudden short circuit, both the high and low voltage sides will be subject to a large short circuit current.
Advantages and disadvantages of dry-type transformers and oil-immersed transformersIn terms of price, dry change is more expensive than oil change.In terms of capacity, large-capacity oils produce more oil than dry ones.Dry transformers need to be used in complex buildings (basements, floors, roofs,
1. Main protection1. Main protection is a protection that meets system stability and equipment safety requirements and can selectively remove protected equipment and line faults as quickly as possible.2. The main protection of the transformer is differential protection and gas protection.1) Differen
