Product Introduction
SCB10 Dry-Type Power Transformer This series of transformers incorporates European dry-type transformer technology to ensure that the products meet strict fire prevention, waterproof and environmental protection standards.
This series optimizes the interlayer voltage and capacitance distribution by improving the high-voltage coil structure, enhancing the ability to resist atmospheric overvoltage and operating overvoltage, and improving the electric field distribution. This series of transformers is an ideal choice for power distribution systems and is often used in subways, shipbuilding, mining, chemicals, power companies, densely populated buildings and other environments with strict safety requirements.

The protection measures for dry-type transformers mainly include the following:
Transformer door travel switch: This switch has 4, each set of normally closed contacts is connected in parallel. When the transformer door is closed, the normally closed contacts are disconnected and there is no electrical signal input for comprehensive protection. If any door is opened, the normally closed contacts are reset and there is an electrical signal input for comprehensive protection. It can be set to alarm or trip the high-voltage cabinet after the door is opened.
Transformer door electromagnetic lock: Used to prevent people from electric shock. When the transformer is powered on, the electromagnetic lock is energized. At this time, the door cannot be opened with the handle and needs to be opened with a special key.
Temperature protection: It is realized through temperature sensors, thermostats and cooling fans. The temperature sensor detects the winding temperature, the thermostat sets the high temperature alarm and over-temperature trip value, and the cooling fan starts cooling when the temperature reaches the set value.
