Installation environmental requirements for dry type cast resin transformers

In the power industry, dry type cast resin transformers are widely used and have great influence. Transformers used in various large enterprises, factories, hospitals, campuses and other important places are basically dry-type transformers. Dry-type transformers rely on air convection for cooling, and are generally used in some lighting and electronic circuits. In the power system, general steam turbine transformers, boiler transformers, ash removal transformers, dust removal transformers, desulfurization transformers, etc. are all dry-type transformers, and dry-type transformers are widely used in large and medium cities, accounting for about 15%~ 20% or so.

When installing dry type cast resin transformers, there are many key points to pay attention to to prevent unnecessary faults or accidents during the installation process. After the transformer is installed, the installation personnel must wear safety helmets correctly when entering the construction site, and it is forbidden to enter the construction site after drinking. When the transformer equipment is being transported, the vehicle should be securely sealed with brown ropes to prevent people and goods from being in the same vehicle. The construction equipment used by the construction personnel must be inspected and qualified, otherwise it cannot be used. After the transformer installation is completed, the doors and windows of the power distribution room must be closed and locked.

Dry type cast resins are commonly used transformer equipment, and their safe use is very important. Therefore, dry-type transformers have very high requirements for their operating environment. The specific requirements of dry-type transformers for the operating environment are as follows:

1.0~40 ℃, relative humidity 80%.

2. Altitude: no more than 2500 meters.

3. Protect from rain, humidity, high temperature, high heat or direct sunlight. There should be a distance of not less than 40cm between its cooling vents and surrounding objects.

4. Avoid working in places with more corrosive liquids, or gases, dust, conductive fibers or metal fines.

5. Prevent operation in vibration or electromagnetic disturbance places.

6. Prevent long-term upside-down storage and transportation, and can not be severely impacted.
