Spark ignition test device for electric blankets under IEC 60335 standard test
Electric blankets are a popular household appliance for keeping warm during the cold season. However, they can also be a potential fire hazard if not used correctly. To ensure their safety, electric blankets undergo a variety of tests, including a spark ignition test.
The spark ignition test is a test that measures the likelihood of an electric blanket catching fire in the presence of a spark. During the test, a small spark is produced near the blanket to see if it catches fire.
If the blanket catches fire, it is deemed to have failed the test and cannot be sold to consumers.
SH9913 electric blanket spark ignition tester according to IEC60335 in the relevant requirements for flexible electric heating appliances, flame resistance test to check whether the flash arc of the charged body caused by the test specimen overheating or burning.
Equipment features and structure: spark ignition test long-snout device is divided into the control box and test bracket two parts, structural components made of stainless steel or brass.
This equipment is a pair of electrodes with an adjustable non-inductive resistor connected in series to a power supply with 10Kv sinusoidal rated output voltage, and then short-circuit the electrodes and adjust the resistor so that through the current is 1ma.
Then the electrodes are short-circuited and the resistor is adjusted so that the current through the electrodes is 1mA, and an arc is generated continuously between the two electrodes, so as to assess whether the test specimen will cause overheating or ignition.
Technical Parameters:
1. power supply: AC220V, 50Hz.
2. electrode: a pair of 3mn copper electrodes, between the distance can be adjusted.
3. the test voltage AC 0 ~ 10kv adjustable; accuracy of 5%.
4. test current 0 ~ 1mA; precision earth 5%.
5. Timing: 1~9min99s.
6. template size: upper and lower template 100X 100X 50mn.
7. digital display.
8. Spark ignition device size: 200X 200X 200m (without heating box).
9. Floor-type pressure-resistant machine device size: 340X 390X 140m, equipment with casters, easy to move.
10. users provide their own high-temperature box.
11. External dimensions:600*500*500mm (Stand not included, stand is placed inside the high)
Through this test, electric blankets can be used with confidence, because they have passed the safety and reliability test. Because they have passed the safety and reliability test.
