本实用新型为一种交直流电焊机无空载安全旁路装置，它主要包括发射单元和接收单元，发射单元内设有频率发生器2，频率发生器2的另一端与信号放大器3的一端连接，信号放大器3的另一端与功率放大器4的一端连接，接受单元内设有电源变压器5，电源变压器5的与功率放大器4一端连接，功率放大器4的另一端与信号判别电路7的一端连接，信号判别电路7的另一端与信号放大器3一端连接，其特征在于：发射单元内设有电源开关电路1，电源开关电路与频率发生器2的另一端连接，发射单元内设有信号发射器8，信号发射器8与功率放大器4的另一端连接，所述接受单元内设有信号接收器9，信号接收器9与信号放大器3另一端连接，电源变压器5与功率放大器6之间设有双向晶闸管10，电源变压器5与功率放大器6之间可设有三只双向晶闸管10，所述电源开关电路1由1.5V电源和光敏电阻连接而成，或是由1.5V电源和光敏二极管连接而成。The utility model is a no-load safe bypass device for an AC/DC electric welding machine, which mainly includes a transmitting unit and a receiving unit, the transmitting unit is provided with a
装置采用1.5V钮口电池，使用时间为180天，产品利用光敏电阻和光敏二极管的特性，作为电源开启和截止，用自耦振荡电路，将频率固定在一定范围内，通过发射单元将频率提高250MZ-350MZ，进行发射，有效距离10M以内，通过接收单元将发射单元的发射信号进行鉴定，鉴定后信号进行放大，产生二个信号，分别为高电平和低电平，高电平使双向晶闸管导通，低电平使双向晶闸管截止，发射单元安装在电焊机的焊柄上，接收单元安装在电焊机的电源和变压器之间，像继电器的开启和关闭。The device uses a 1.5V button battery, and the use time is 180 days. The product uses the characteristics of photoresistors and photodiodes to turn on and off the power supply, uses an auto-oscillating circuit to fix the frequency within a certain range, and increases the frequency through the transmitting unit. 250MZ-350MZ, for transmission, the effective distance is within 10M, the transmission signal of the transmission unit is identified by the receiving unit, the signal is amplified after identification, and two signals are generated, which are high level and low level, and the high level makes the bidirectional thyristor Conduction, the low level makes the bidirectional thyristor cut off, the transmitting unit is installed on the welding handle of the electric welding machine, and the receiving unit is installed between the power supply of the electric welding machine and the transformer, like the opening and closing of a relay.
在使用时，手握焊柄，挡住光线，光敏二极管无光通过，电阻极小，电源可以畅通无阻通过，去推动后级自耦振荡电路公司，使得发射单元将高频信号发射(高电平信号)，当放下焊柄时，有光通过，电阻极大，电源基本被切断，通过分路电源，去推动后级自耦振荡电路工作，使得发射电源将高频信号发射出去(低频信号)。When in use, hold the welding handle to block the light, the photodiode passes through without light, the resistance is extremely small, and the power supply can pass through unimpeded, to push the post-stage auto-oscillating circuit company, so that the transmitting unit transmits high-frequency signals (high level Signal), when the welding handle is put down, light passes through, the resistance is extremely large, and the power supply is basically cut off. Through the shunt power supply, the post-stage self-coupling oscillation circuit is driven to work, so that the transmitting power supply emits high-frequency signals (low-frequency signals) .
接收单元电源于380V电压变压为19V，经桥式整流，作接收单元的电路电源，用接收单元将发射单元发射信号进行鉴定、校对后将正确信号进行放大，高电平或低电平，高电平使双向晶闸管导通，低电平使双向晶闸管截止，双向晶闸管耐压1000V，击穿电流40A。The power supply of the receiving unit is transformed from 380V to 19V, and is rectified by bridge to serve as the circuit power supply of the receiving unit. The receiving unit is used to identify and verify the signal transmitted by the transmitting unit, and then amplify the correct signal, high level or low level, The high level makes the bidirectional thyristor turn on, and the low level makes the bidirectional thyristor cut off.
