在八分邮票出售机中,原找币电路“找3”是由“找1”和“找2”两只找币电磁铁同时打币来完成的。每只电磁铁的吸动电流为1A左右。两只电磁铁同时打币时,电路中瞬间动作总电流可达2A左右。这样大的电流在电源变压器内引起的压降较大,使整流输出电压降低,造成打币舌的打币力量不足。为了提高打币舌的打币力量,在找币电路上我们作了 In the eight stamps sales machine, the original find coins circuit “find 3 ” is “find 1 ” and “find 2 ” two to find the coin solenoid while playing the money to complete. The suction current of each electromagnet is about 1A. Two electromagnets at the same time playing currency, the circuit instantaneous total current up to 2A. Such a large current in the power transformer caused by the pressure drop larger, so that the rectified output voltage is reduced, resulting in playing the currency of the currency’s lack of strength. In order to improve the currency hit the coin strength, we find the circuit in money
