The types of oil transformer protections, from a Chinese custom transformer manufacturer.
The protection equipment of 10kV oil-immersed distribution transformer mainly includes circuit breaker, load switch and fuse.
Circuit breaker also known as switch, in the circuit from the role of connecting and breaking circuit, but it has a strong “arc” ability, so it can not only control the breaking of electrical appliances, and short circuit will automatically trip.
Load switch is developed on the basis of isolating switch, namely knife switch. It has good operation capability and can also cut off load current. It has certain “arc extinguishing” ability, but the “arc extinguishing” ability is not big.
A fuse is also called insurance. It also plays a role in connecting and disconnecting circuits. In its capacity range, has a strong “arc extinguishing” ability, can be used for the protection of electrical equipment.
