BDH-20KV arc resistance tester

1、 Characteristics and selection functions of arc resistance tester:

1. The experiment can be automatically conducted according to the table below and display the various experimental processes.

Note: With the continuous updates of national standard versions, we will provide program chips that comply with the new versions of national standards to ensure that users' software is constantly upgraded.

2. Arc on-off time error: less than ± 10ms.

3. A new electrode holder has been designed in accordance with the requirements of IEC 61621-1997. This new electrode holder can adjust the electrode to sample pressure to 0.5 ± 0.05N, and can align the two electrodes; The distance and angle between electrodes can be adjusted to ensure that all parameters meet the standard requirements.

4. Can automatically run continuous arc tests of 10, 20, 30, and 40mA.

2、 Characteristics and Selection of Arc Resistance Tester, Main Scope of Application

This testing machine is mainly suitable for testing the arc resistance performance of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulation oil, insulation paint, cardboard and other media;

The arc resistance testing machine is computer-controlled, and the test curve can be observed online during the testing process; The automatic storage of test conditions and test results data, as well as the ability to access, display, and print the arc resistance of materials, refers to the phenomenon where, when an arc discharge occurs near the surface of a solid insulating material, a carbonized conductive path is formed on the surface of the sample due to heat, chemical decomposition, or erosion, resulting in the loss of insulation performance.

3、 Usage standard:

The BDH-20KV arc resistance tester is designed and manufactured according to GB 1411-78 "Solid Electrical Insulation Materials High Voltage Small Current Intermittent Arc Resistance Test Method", IEC 61621 and AST D495, and complies with JEC 149, UL 746A and other test methods.

This instrument applies 12500V voltage and 10-40mA power frequency arc current continuously from the gap to two tungsten rod electrodes 6.35mm apart, subjecting the surface of the sample to gradually harsh arc conditions, thereby finely distinguishing the material's arc resistance. The evaluation result is the total time from arc generation to material damage.

It is widely used in the evaluation of arc resistance performance of insulation materials such as plastics, resin adhesives, and insulating paints for electrical purposes in industries such as motors, appliances, and household appliances.

The BDH-20KV arc resistance tester has added a new program developed in accordance with IEC 61621-1997 in order to adapt to the upcoming new national standard (equivalent to IEC 61621-1997). It can be used for both current national standards and can operate according to new national standards and IEC standards.
