Normally, a standard arc flame leads to carbonization on the material's surface, eventually turning it conductive. The precise time for the arc to extinguish is accurately measured in seconds. With two tungsten electrodes placed at a calculated interval on the sample plate,the arc begins intermittently and progressively shortens until it forms a continuous arc as the current intensifies. The material then faces increasingly severe arc conditions, resulting in eventual failure. Arc resistance is crucial for insulating materials used in high-voltage switches or low-voltage high-current switches, which frequently encounter arcs during operation. Only those materials that exhibit outstanding arc resistance are deemed suitable.In the field of electrical and electronic devices, insulating materials subjected to high-voltage, low-current arc discharges display unique surface damage patterns near the arc. These discharges bring about localized thermal and chemical deterioration and corrosion, ultimately creating a conductive pathway on the material. Upon formation of a conductive channel, the material is considered to have failed the test.The Arc Resistance Tester complies with standards such as GB1411, IEC61621, ASTM C495, and UL746A, rendering it an indispensable tool for conducting simulated safety testing procedures.Meticulously designed to meet stringent standard requirements, the arc resistance tester boasts comprehensive electrical schematics along with high-precision electrodes, ensuring precise and reliable testing results.Product ParametersArc on/off time errorAll program segments are superior±1msVoltage regulator capacity1kVARated test voltage12.5kVMaximum test voltage15kVElectrode pressure on sample(0.5±0.05)NElectrode materialTungsten barsTest voltage accuracy<1.5%Current measurement accuracy<1.5%Distance between electrodes(6.35±0.1)mm(IEC) (6.0±0.1)mm(ASTM)Ambient temperature(23±2)oCAmbient humidity(50±5)%Power supply220V±5% 50Hz 10AProgram segmentArc current mAArc on&off time /sDuration of each program segment/sTotal test time/sIEC 61621ASTM D4951101/8son 7/8s off1/8son 7/8s off60602101/4s on 3/4s off1/4s on 3/4s off601203101/4s on 1/4s off1/4s on 1/4s off60180410Continuous power on60240520Continuous power on60300630Continuous power on60360740Continuous power on60420Note:Ensure all instruments and equipment are properly grounded, maintaining a grounding resistance of ≤4Ω for optimal safety and performance. ,The Supply and Demand parties agree that the supplier will provide all necessary technical specifications, while the demander is tasked with establishing their own grounding system to ensure compliance and safety.Exhibition photos
