Breakdown strength testing Machine/Withstand voltage tester/e test device/Dielectric strength tester ASTM D149
Scope of use
Mainly applicable to solid insulating materials such as: plastic, film, resin, mica, ceramics, glass, insulating paint and other media at power frequency voltage or DC voltage breakdown strength and voltage resistance time test. The instrument adopts computer control, through man-machine dialogue, complete the power frequency voltage breakdown of the insulating medium, power frequency voltage withstand test.
Main functions:
1. The test curve can be dynamically drawn during the test, and the test curve can be superimposed and contrasted with a variety of colors.
2, the test data can be edited and modified, flexible application;
3, test conditions and test results and other data can be automatically stored;
4, the test report format is flexible, suitable for different needs of different users;
5. The validity of curve data in a group of tests can be artificially selected;
6. Test result data can be imported into EXECL,WORD document editing;
7, the overcurrent protection device has enough sensitivity to ensure that the sample breakdown in 0.1S cut off the power supply;
8, the durability of the instrument operation: the instrument can be continuously operated and used, and there is no need to stop regularly to protect the instrument.
9, the software can set the administrator and each user's own parameters and report storage permissions.

Equipment safety protection functions: 1, the equipment should be installed with a separate protective ground wire, mainly to reduce the strong electromagnetic interference generated around the sample breakdown. It can also avoid controlling the computer out of control. 2, DC test discharge alarm function: when the equipment completes the DC test, when the test door is opened, the equipment will automatically alarm, until the discharge device on the equipment is discharged, the alarm will automatically cancel. 3, with the addition of the test manual discharge device, with the host for integration, when the DC test process suddenly power off, can use manual discharge rod for discharge, to ensure the personal safety of the test personnel. 4, the circuit of the test equipment is equipped with a number of protection measures, mainly: overcurrent protection, voltage loss protection, leakage protection, short circuit protection, DC test discharge protection.
Products comply with:
GB/T1695-2005 vulcanized rubber power frequency voltage breakdown strength and withstand voltage strength test GB/T 1408-2006 Test method for electrical strength of insulating materials GB/T3333 power frequency voltage breakdown test method HG/T 3330 insulating paint film breakdown strength determination GB12656 capacitor paper frequency voltage breakdown test method and ASTM D149 standard requirements.
