Scope:
Glow wire tester suitable for lighting equipment, electric and electronic products, and its group of low-voltage electrical appliances, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instrumentation, information technology equipment, electrical business equipment, electrical fittings and accessories piece parts, production and quality control departments, also applies to the insulation, plastic or other solid combustible materials industry;
Standard:
Glow-wire test IEC60695-2-10: 2000 to IEC60695-2-13: 2000 "Glowing / Hotline, the basic test methods, the glow-wire test device and general test procedures" and GB4706.1 and GB/T5169, UL746A IEC829 , DIN695, VDE0471 standards require the use of flame ignition source simulation project;
Basic principles:
Glow Wire Tester provisions the material (Ø4 Ni80/Cr20) and the shape of the electric wire with a large current is heated to the test temperature (550 ° C to 960 ℃) 1min after a prescribed pressure (1.0N) vertical scalding the test 30s, depending on whether the test items and bedding material from the fuel or holding burning time determination of electric and electronic equipment finished fire risk; ignitability determination of solid insulating materials and other solid combustible materials, ignition temperature (GWIT), flammable and combustible Index (GWFI);
Main features:
1. Glow Wire Tester test chamber part and control part of the integrated design, easy on-site installation and commissioning. Test chamber shell and important parts made of stainless steel, smoke, gas corrosion resistance; purpose of using the regulator manual adjustment of energy-efficient test current to achieve precise control of temperature; time, temperature, digital display, the observation is convenient and reliable to use.
2 with a purity of 99.8% and a thickness of 0.06mm, the side length of 2mm square silver on the glow-wire at the top of the upper surface of the temperature measurement system calibration temperature of 960 ° C, heartburn hot filament to the silver melt, the temperature is 960 ℃ ± 15 ℃. Test the temperature of the glow-wire thermocouple, armored metal sleeve at least 1050 ° C the temperature capability. Using suction fit relay to control the depth of the glow-wire burned into the sample and has a regulatory function, with 7mm stainless steel measuring gauge, accurate and efficient. 4. Imports thermocouple and temperature control accurate.Thermocouple accessories dedicated thermocouple connector, plug and replace convenient. Contact with a wire measured items, equipment continue to supply 2S within the sample car returned to cut off the current, to ensure that the test accurately.6 with mesh adapter sample holder, convenient clamping profiled and small test sample. Lighting using standard explosion-proof lamps, to ensure that the experiment does not communicate with the outside world, in line with standard experimental requirements. Time using imported relays and counters, and other components of domestic brand-name.
