In the field of electrical safety testing, the IEC60065 dielectric strength test device plays a crucial role. This article will take you through its advantages, standards, principles, materials, and structure.

1. What is the dielectric strength test device?

The IEC60065 dielectric strength test device is a professional equipment for electrical safety testing. It mainly conducts anti - electric strength tests on various electrical and electronic devices based on the IEC60065 and UL1310 standard, ensuring that these devices will not cause safety accidents such as electric shock to users due to insulation problems during normal use. It’s applied to test the electric strength of thin-layer insulation material.

2. Structure of the dielectric strength test apparatus

The dielectric strength test apparatus is made of the insulating base, terminals for test voltage, metal frame, 6.8mm/50g test pin and 5mm/100g test pin.

3. Principle

The dielectric strength test instrument applies voltage to the test material, this is to detect the insulation performance of the test material under specific conditions is tested. This device cannot function independently. Instead, operator needs to use it in conjuction with a withstand voltage tester.

4. Operation

First to place the sample between the two metal rods

Second to connect the high-end and low-end of the high-voltage rod of the withstand voltage tester with the red and black terminals of the dielectric strength test device

Third to set the initial voltage: The starting voltage U applied to the test material at the beginning. Not more than half of the specified voltage value Ut‌.

Fourth to increase the voltage: Rapidly increase the test voltage to the full value and maintain it at this voltage value for 1 minute‌.

Fifth to measure the insulation resistance: Measure the insulation resistance after 1 minute. If the insulation resistance is not less than the specified value and no arcing or breakdown occurs during the dielectric strength test, the material is considered to meet the requirements‌.

5. Maintenance

The maintenance of the device is also very important, it needs to regular wiping of the body with cotton wool dipped in alcohol or anti-rust oil, and regular lubrication of the bearing positions.
