Arc Ignition Fire Testing Equipment High Current For Insulation Materials

IEC 60950-1 High Current Arc Ignition Testing Machine for Insulation Materials

Product Overview:

According to the IEC 60950-1:2001 "security of information technology equipment" and UL746A, IEC60947.1: 1999 and other standards stipulated safety simulation test project. The high-current ignition arc ignition tester adopts two electrodes, and according to a certain current (33A) and power factor (COSφ0.5), according to a certain arc striking speed (254mm/s) and repetition frequency (40 times/min), Repeatedly arcing 200 times on the surface of the test object, and igniting to evaluate the high current arc ignition performance of the sample.

Test description: Insulation materials or other parts of solid combustible materials that easily spread flames inside electrical and electronic equipment may ignite due to proximity to or contact with arcs, causing electrical fires and endangering the reliable operation of equipment and personal safety.

Complies with the standards:

In accordance with IEC 60950-1:2001, BS EN 60950-1::2001, BS 7002:2001, GB 4943-2001 "Safety of Information Technology Equipment" and UL746A, IEC60947.1:1999, GB/T14048.1 -2000, IEC730.1:1993, GB14536.1-1998 and other standards.

Scope of application:

It is mainly applicable to the arc-resistance performance test of electric and electronic products, household appliances and their materials. Simulating the electricity between different live parts or between live parts and grounded metal parts may cause leakage on the insulator. To measure and evaluate the arc-resistance of the insulator at the specified voltage.

Test description:

The high current arc ignition pilot tester is a two-electrode using the specified size and different materials (static electrode - copper and electric pole - stainless steel), at a specific current (33A) and power factor (COS φ0.5), press A certain arc striking speed (254mm/s) and repetition rate (40 times/min) were repeated on the surface of the test specimen 200 times. No igniting was used to evaluate the high-current arc ignition resistance of the specimen (HAI) ). The smaller the level number, the more difficult it is to burn the material.
