Electric strength test device
Electric strength test device is designed and manufactured according to IEC 60065, GB8898 and UL1310 standards, a thin layer of insulating material for electric strength test.
Dielectric strength test device support part with reference to Figure 6 of the design, integral structure, 304 slab material processed. To improve the performance of the insulation board anti-creepage surface of brushed polished part from the backplane edge of the bracket the minimum distance of> 35mm, designed to meet 2000 meters above sea level 12 KV strength test requirements.
The device works: the beginning of the initial voltage U applied in the test material. Not more than half of the specified voltage value Ut, and then quickly test voltage is increased to full value and keep the value of the voltage 1min. Measured after 1min Insulation resistance not less than the specified value, and during the electric strength test, no flashover or breakdown, that the materials meet the requirements.

Installation of
A. ??? Operating Environment: Humidity: 18-32 ° C, Humidity: 50% -70% RH is appropriate.
Two. ??? Need to install a stable level of insulation on the table.
3. ??? Adjustment of four supporting legs, the instrument at the state level.
Use of the device:
A. ??? Will be the test sample placed between two metal poles.
Two. ??? Connected to pressure test the device, adjusting the corresponding value of the test voltage and leakage current.
3. ??? After the passage of the voltage test, insulation resistance value of the need to test materials, its value can not be less than the specified value.
