Solid Insulation Material Electrical Strength Testing Machine
IEC60243-1 Lab Teter
Compliance with standards:
Meets the requirements of GB1408.1, IEC60243-1 "Test Methods for
Electrical Strength of Solid Insulation Materials - Tests at Power
Frequency", GB1408.2, IEC60243-2 "Test Methods for Electrical
Strength of Solid Insulation Materials - Corresponding DC Voltage
Test" GB/T1695-2005 "Determination of Power Frequency Breakdown
Voltage and Withstand Voltage of Vulcanized Rubber" GB/T3333
GB12656 and ASTM D149 test standards.
Scope of application:
Mainly applicable to solid insulation materials such as plastics,
films, resins, mica, ceramics, silicone, glass, insulation paints,
etc., for measuring breakdown strength and withstand time at power
frequency (48-62Hz) or corresponding DC voltage in air or liquid
media. Suitable for continuous and uniform voltage boosting or
step-by-step voltage boosting, apply AC/DC voltage to the sample
until breakdown, measure the breakdown voltage value, and calculate
the breakdown strength of the sample; Using a rapid voltage boost
method, raise the voltage to the specified value and maintain it
for a certain period of time until the sample does not break down.
Set the specified value at this time as the withstand voltage value
of the sample.
Usage:
Take out the discharge rod, straighten the telescopic rod, insert
the other end of the grounding clip into the metal probe hole of
the discharge rod, and then clamp the grounding clip onto the
instrument grounding terminal A or B. Hold the insulated handle as
far away from the instrument housing as possible, stand up, bend
forward slightly, open the glass door of the test box, and use the
metal probe to touch the output voltage equalizing ball of the
high-voltage transformer, the electrode on the sample, and the
high-voltage end of the capacitor one by one. (If necessary, after
the discharge is completed, use a multimeter in AC voltage mode
(AC20V) to test that the voltage between the electrode and the
human body is less than 36V, indicating that the residual voltage
has been completely discharged.)
Attention: Before taking out the sample after each experiment, it
is necessary to fully discharge it in advance. During discharge,
the contact residence time at each discharge point should exceed 2
seconds.
Safety instructions:
1. The equipment needs to be equipped with a separate protective
grounding wire. Grounding protection is mainly used to reduce the
strong electromagnetic interference caused by the breakdown of the
sample to the surrounding area. It can also prevent the computer
from losing control.
2. The circuit of the experimental equipment is equipped with
multiple protection measures, mainly including overcurrent
protection, voltage loss protection, leakage protection, short
circuit protection, DC test discharge alarm, etc.
3. Grounding requirements: Separate grounding is required, and the
grounding should comply with national standards. The metal rod
should be buried at least 1.5 meters deep underground.
4. The circuit of the experimental equipment is equipped with
multiple protection measures, mainly including overcurrent
protection, voltage loss protection, leakage protection, short
circuit protection, DC test discharge alarm, etc.
