IP protection level is a standard for
evaluating the protective performance of electronic equipment. IP stands for
"International Protection", which is the international protection
level. The IP protection level is composed of two numbers, the first number
represents the protection level for solid substances, and the second number
represents the protection level for liquid substances. By testing the IP
protection level of electronic equipment, one can understand its protection
ability against solid and liquid substances, in order to determine its scope of
use and working environment.
IP protection level detection is the process of
placing equipment in a specific testing device, simulating the required
protection level of the equipment, conducting a certain period of testing, and
determining its protection level against solid and liquid substances by
observing the performance of the equipment during the testing process. After
the test is completed, assign the corresponding IP protection level to the
equipment based on the test results.
IP protection level testing for new energy vehicle on-board power supplies, including dustproof and waterproof tests.
The purpose of both waterproof and dustproof tests is to verify whether the DUT casing protection level meets the specification requirements. The judgment standard for dust prevention test is that there is no obvious dust deposition inside the shell after the test, which means the test is considered qualified.
The judgment standard for waterproof
testing is to check whether the water sensitive sticker has changed color, and to
check the water ingress situation of the shell. If there is water ingress, it
should not be enough to affect the normal operation of the equipment or damage
safety; Water does not accumulate on insulation components that may cause
leakage marks along the creepage distance; Water does not enter live parts or
windings that are not allowed to operate in a damp state; Water does not
accumulate near the cable head or enter the cable. After the test, open the
cover to check for water ingress. (If requested by the customer, perform
voltage withstand testing and insulation testing.)
