What does the protection level of dry type transformer IP00 mean?

1. IP protection level: indicates the dustproof and moisture-proof characteristic level of electrical equipment, which is composed of IP and two digits.

IP is the prefix of "ingress protection", and the number indicates the level of protection.

2. IP30:

Dustproof level: prevent the intrusion of solid foreign objects with a diameter larger than that;

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

3. IP50

Dustproof level: Prevent foreign objects and dust.

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

Level definition. IP stands for Ingress ProtectionIEC IP protection level is an important criterion for the safety protection of electrical equipment. The IP rating system, which provides a way to classify products according to the degree of dust, water and collision resistance of electrical equipment and packaging, is recognized by most European countries, drafted by the International Electro Technical Commission (IEC) and published in IED529 (BS EN 60529:).

1992).

The first digit indicates the level of protection against the ingress of solid matter such as particles. 4--- means to prevent the intrusion of solid foreign objects larger than the diameter.

The second digit indicates the degree of containment against moisture and water intrusion, and the higher the number, the higher the level of protection. 0--- indicates that there is no special protection reference against water or moisture.

According to GB 4208-2008 "Enclosure Protection Rating (IP**)".

The second characteristic digit in IP** stands for waterproofing and is specified as follows:

1. Definitions. IP protection level: indicates the dust and moisture resistance characteristic level of electrical equipment, which consists of IP and two-digit delay numbers.

IP is the prefix of "Ingress Protection", and the number indicates the level of protection.

The first digit: indicates the level of the electrical equipment's ability to prevent the intrusion of foreign objects, the highest level is 6;

The second digit: indicates the degree of containment of electrical hail equipment against moisture and water intrusion, and the highest level is 8.

2. IP30:

Dustproof level: prevent the intrusion of solid foreign objects with a diameter larger than that;

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

3. IP50

Dustproof level: Prevent foreign objects and dust. That is, it completely prevents the intrusion of foreign objects, and has a certain dust-proof performance, but does not completely prevent the incursion of dust, and the amount of dust intrusion will not affect the safe operation of electrical equipment;

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

The enclosure protection level (IP**) is to classify the product according to its dustproof, anti-foreign intrusion, waterproof, and moisture-proof characteristics. The foreign objects referred to here, including tools and human fingers, should not touch the live part of the lamp to avoid electric shock. It is generally composed of two numbers, the first number indicates the level of dust protection and prevention of foreign objects intrusion of the product; The second number indicates how tightly the product is sealed against moisture and water intrusion.

The higher the number, the higher the level of protection. For example, an example of an enclosure protection rating (IP**) is as follows:

IPXX, dust resistance rating (the first X denotes).

0: No protection.

1: Prevent the intrusion of large solids.

2: Prevents the ingress of medium-sized solids.

3: Prevent small solids from entering and intruding.

4: Prevent the entry of solids larger than 1mm.

5: Prevent harmful dust accumulation.

6: Completely prevent dust from entering.

Waterproof rating (indicated by the second x).

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect 3: Water or rain has no effect from the corner of 60 degrees to the shell.

4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment in the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

The standards for enclosure protection (IP**) are:

1) International protection and waterproof test standards drafted by IEC (International Electrotechnical Commission): IEC 529 598;2) GB 700 86;3) GB 4208, etc.

Enclosure Rating (IP**) Laboratory:

At present, the laboratories that can carry out IP level tests mainly include Suzhou Electrical Appliance Research Institute, Environmental Reliability and Electromagnetic Compatibility Test Center, Aerospace Environmental Reliability Test and Testing Center, etc.

It is the protection level, the front position is dustproof, and the back is waterproof.

To put it simply, the higher the number of dustproof and waterproof levels of the product, the higher the protection level.
