Test Device
Product Information For IK Pendulum And Vertical Impact Test
Device:
Standard: IEC60068-2-75:1997” Environment testing for electric and
electronic products Part2: Test methods Test Eh: Hammer tests IDT”
IEC62262:2002 "Degrees of protection provided by enclosures for
electrical equipment against external mechanical impacts (IK code)"
Sample: Electric vehicle charging pile
Test purpose: It is used for the mechanical strength test of
electric vehicle charging piles used for charging vehicles, and is
also used for the mechanical strength verification of metal sheets
such as transformer cabinets and non-metallic electric energy
metering cabinets
Test principle: According to the test Eha: pendulum, the impact
element is freely released at a certain height through a 1-meter
pendulum tube, and hits the sample at the lowest point in the
vertical direction, and through the conversion of gravitational
potential energy to kinetic energy, the purpose of impact testing
on the sample is achieved.
According to the test Ehc: vertical drop hammer, the impact element
is released freely at a certain height, falls vertically in a
static state, hits the sample, and through the conversion of
gravitational potential energy to kinetic energy, the purpose of
impact testing on the sample is achieved.
Structure For IK Pendulum And Vertical Impact Test Device:
1. The trolley structure is adopted, the mounting bracket seat can
be adjusted up and down, and the impact angle can be adjusted to
match the height requirements of charging piles of different sizes
and different impact points of charging piles
2. The motor is used to drive the lifting, which is easy to operate
3. Both pendulum and vertical impact are released by electromagnet
4. The pendulum has the function of anti-secondary impact
