Overview and Protection Levels of Marine Transformers

Overview of marine transformers:

A marine transformer is a machine that acts on marine electrical equipment, and its degree of use depends on the normal use of the ship. The protection level of marine transformers also came into being. Many marine transformer manufacturers manufacture transformer enclosures according to the protection level. It can also be said that who can Whoever makes a good protection level will be competitive.

The protection level of marine transformers, such as marine transformers (IP20), is followed by the protection level unit, where IP refers to the dustproof and waterproof level of the transformer, 2 refers to the dustproof level, and 0 refers to the waterproof level. The meaning of each level is shown in the table below. :

What is the protection level of marine transformers?

Description of digital protection scope:

0 has special protection against water or moisture.

1 Water droplets invade vertically falling water droplets (such as condensed water) and will not damage the appliance.

2 When tilted at 15 degrees, it can still prevent the intrusion of water droplets. When the appliance is tilted from vertical to 15 degrees, dripping water will not damage the appliance.

3. Prevent the sprayed water from intruding into the rainproof or electrical appliances with an angle of less than 60 degrees from the vertical.

4. Prevent splashing water from invading, and prevent water splashing in all directions from invading the electrical appliance and causing damage.

5. Prevent the intrusion of water spray, and prevent the water from the nozzle flying from all directions from invading the electrical appliance and causing damage.

6 The electrical appliances on the deck can prevent the intrusion of large waves, and can prevent the damage caused by the intrusion of large waves.

7. Soak the appliance in water for a certain time or the water pressure is lower than a certain standard to ensure that it will not be damaged by soaking.

8. Prevent the electrical appliance from sinking under the specified water pressure indefinitely during the sinking process to ensure that it will not be damaged by water immersion.

What is the dustproof rating of marine transformers?

Description of digital protection scope:

0 No special protection for outsiders.

1 Prevent the invasion of solid foreign objects with a diameter greater than 50mm, prevent the human body (such as the palm) from accidentally touching the internal parts of the electrical appliance, and prevent the invasion of large-sized (diameter greater than 50mm) foreign objects.

2 Prevent the intrusion of solid foreign objects with a diameter greater than 12mm, prevent fingers from touching the internal parts of the electrical appliance, and prevent the intrusion of medium-sized (diameter greater than 12.5mm) foreign objects.

3 Prevent the intrusion of solid foreign objects with a diameter greater than 2.5mm, and prevent the intrusion of tools, wires and similar small foreign objects with a diameter or thickness greater than 2.5mm, and contact with the internal parts of the electrical appliance.

4 Prevent the intrusion of solid foreign objects with a diameter greater than 1.0mm Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 1.0mm from invading and contacting the internal parts of the electrical appliance.

5 Prevent foreign objects and dust Completely prevent foreign objects from intrusion, although it cannot completely prevent dust intrusion, the amount of dust intrusion will not affect the normal operation of electrical appliances.

6 Prevent foreign objects and dust completely prevent the intrusion of foreign objects and dust.
