Product introduction
Rated voltage of electromagnetic coil:
1. The electromagnetic coil should work normally within the range of rated voltage (110% ~ 85%) V;
2. When the rated voltage is alternating current, it is expressed by Arabic numeral value of the letter AC suffix voltage value, and the alternating frequency is indicated; When the rated voltage is DC, it is expressed by the Arabic numeral value of the letter DC suffix voltage value.
Electromagnetic coil resistance:
1. Unless otherwise specified, the resistance value of the coil is 20℃;
2. The resistance should be within the tolerance range: 5% (when the standard resistance is less than 1000 Ω) or 7% (when the standard resistance is ≥1000 Ω).
The number of turns of electromagnetic coil shall meet the specified requirements, and the tolerance of turns shall be as follows:
Number of turns of electromagnetic coil: 0~300, corresponding number of turns tolerance: 0
Number of turns of electromagnetic coil: > 300~500, corresponding number of turns tolerance: 3 turns.
Number of turns of electromagnetic coil: > 500~20000, corresponding number of turns tolerance: 0.6%
Number of turns of electromagnetic coil: > 20,000 ~ 60,000, corresponding number of turns tolerance: 1.5%.
The number of turns of the electromagnetic coil can be measured by a coil number tester.
Test method of turn-to-turn withstand voltage: Take a reference coil and another coil as the coil to be tested, and apply a specified impulse voltage wave between the terminals of the two coils or between the lead wires at the head and tail for 1 s to 3 s. Compare the similarities and differences between the two attenuated oscillation waveforms, and the product difference should be less than 20% compared with the reference waveform.
Regulation of impulse voltage wave in turn-to-turn withstand voltage test;
Rated voltage U<60 power frequency withstand voltage and turn-to-turn withstand voltage test voltage ≥1000.
Rated voltage 60≤U<300 power frequency withstand voltage and turn-to-turn withstand voltage test voltage ≥2000.
Rated voltage 300≤U<600, power frequency withstand voltage and turn-to-turn withstand voltage test voltage ≥2500.
