背景技术Background technique

One end is connected to one end of the magnetic trip switch, the other end of the magnetic trip switch and the main pole T2 of the triac and one end of the power supply circuit of the electrical equipment form a closed loop.
所述的待机断电电路包括变压器、两个稳压二极管、电阻R1、电阻R2、二极管D1、二极管D2、电解电容C1、电解电容C2和场效应管，所述的变压器的初级线圈串联接入用电设备的供电电路的另一端中，变压器的次级线圈与电阻R1并联，在电阻R1的两端并联两个反向串联的稳压二极管；所述的电阻R1的一端与二极管D1的阳极和二极管D2的阳极同时连接，二极管D1的阴极与电解电容C2的一端连接后同时与场效应管的源极连接；二极管D2的阴极分别与电阻R2的一端和电解电容C1的一端同时连接后与场效应管的栅极连接；电阻R1的另一端与电阻R2的另一端、电解电容C1的另一端和电解电容C2的另一端同时连接后与磁力脱扣开关电路的负输入端连接；并且磁力脱扣开关电路的正输入端与场效应管的漏极连接。如此设置，如图1所示，由于长时间工作且工作电流变化的设备在工作时电流时高时低，电流低时与该用电设备待机时的电流几乎没有差别，因此长时间工作且工作电流变化的设备不能根据电流的变化来判断该用电设备是否处于待机状态，但是由于该设备在工作时电流低时的时间不会持续很久，当设备进入待状态后，工作电流才会长时间保持低电流状态。因此本实用新型的长时间工作且工作电流变化的设备的待机断电节能电路是这样实现的：The standby power-off circuit includes a transformer, two zener diodes, a resistor R1, a resistor R2, a diode D1, a diode D2, an electrolytic capacitor C1, an electrolytic capacitor C2 and a field effect transistor, and the primary coil of the transformer is connected in series In the other end of the power supply circuit of the electrical equipment, the secondary coil of the transformer is connected in parallel with the resistor R1, and two Zener diodes in reverse series are connected in parallel at both ends of the resistor R1; one end of the resistor R1 is connected with the anode of the diode D1. It is connected with the anode of the diode D2 at the same time, the cathode of the diode D1 is connected with one end of the electrolytic capacitor C2 and then connected with the source of the FET; the cathode of the diode D2 is connected with one end of the resistor R2 and one end of the electrolytic capacitor C1 at the same time. The gate of the field effect transistor is connected; the other end of the resistor R1 is connected with the other end of the resistor R2, the other end of the electrolytic capacitor C1 and the other end of the electrolytic capacitor C2 at the same time and then connected to the negative input of the magnetic trip switch circuit; and the magnetic force The positive input terminal of the trip switch circuit is connected with the drain of the field effect transistor. In this way, as shown in Figure 1, because the device that works for a long time and the working current changes, the current is high and sometimes low during operation, and there is almost no difference between the current when the current is low and the current of the electrical equipment when it is in standby, so it works for a long time and works. A device with a changing current cannot judge whether the electrical device is in the standby state according to the change in the current, but because the device does not last for a long time when the current is low during operation, when the device enters the standby state, the working current will only last for a long time. maintain a low current state. Therefore, the standby power-off energy-saving circuit of the equipment that works for a long time and the working current changes of the present invention is realized as follows:
将该待机断电节能电路串联接入到长时间工作且工作电流变化的用电设备的供电电路中，打开磁力脱扣开关(若用电设备的启动电流大于额定电流，需在供电电路中并联一只大容量开关，先开启大容量开关，启动完成后再打开磁力脱扣开关)，使设备通电，供电电流通过变压器输出经电阻R1后，在电阻R1的两端产生电压，此电压经过两个两个反向串联的稳压二极管箝压后，由二极管D1和二极管D2分别给电解电容C1和电解电容C2充电。此时，无论设备的工作电流如何变化，电解电容C1的电压下降只能通过其对电阻R2的放电实现，因此只要保证电解电容C1和电阻R2的放电速率不大于一定的速率，电解电容C1就可以使变压器得到不断的电量补充。当供电电流过小时，电解电容C1和电阻R2的放电速率大于一定的速率，则该待机断电节能电路开始进入延时断电过程，延时时间由电阻R2和电解电容C1的数值参数决定。并且由于电解电容C2在P型效应管的截止作用下，只能通过型场效应管的S-D之间漏电。当供电电流长时间过小时(即用电设备进入待机状态)，电解电容C1和电解电容C2得不到及时的电量补充，此时电解电容C2两端的电压下降速度大大低于电解电容C1两端电压的下降速度，两者的电压差而将开启场效应管，场效应管提供电解电容C2对光电耦合双向可控硅驱动器放电，触发双向晶闸管，双向晶闸管触发后使磁力脱扣工作，带动开关复位，此时供电电路被切断。Connect the standby power-off energy-saving circuit in series to the power supply circuit of the electrical equipment that works for a long time and the working current changes, and turn on the magnetic trip switch (if the starting current of the electrical equipment is greater than the rated current, it needs to be connected in parallel in the power supply circuit A large-capacity switch, first turn on the large-capacity switch, and then turn on the magnetic trip switch after the startup is completed), so that the equipment is energized, the power supply current is output through the transformer through the resistor R1, and a voltage is generated at both ends of the resistor R1. After being clamped by two Zener diodes connected in reverse series, the electrolytic capacitor C1 and the electrolytic capacitor C2 are charged by the diode D1 and the diode D2 respectively. At this time, no matter how the operating current of the device changes, the voltage drop of the electrolytic capacitor C1 can only be realized by the discharge of the resistor R2. Therefore, as long as the discharge rate of the electrolytic capacitor C1 and the resistor R2 is not greater than a certain rate, the electrolytic capacitor C1 will The transformer can be continuously replenished with electricity. When the power supply current is too small, the discharge rate of the electrolytic capacitor C1 and the resistor R2 is greater than a certain rate, and the standby power-off energy-saving circuit starts to enter the delay power-off process. The delay time is determined by the numerical parameters of the resistor R2 and the electrolytic capacitor C1. And because the electrolytic capacitor C2 is under the cut-off action of the P-type effect transistor, it can only leak electricity between the S-D of the type FET. When the power supply current is too small for a long time (that is, the electrical equipment enters the standby state), the electrolytic capacitor C1 and the electrolytic capacitor C2 cannot be replenished in time. At this time, the voltage drop across the electrolytic capacitor C2 is much lower than that across the electrolytic capacitor C1. The falling speed of the voltage, the difference between the two voltages will turn on the field effect transistor. The field effect transistor provides the electrolytic capacitor C2 to discharge the photoelectric coupling triac driver, triggering the triac. After the triac is triggered, the magnetic tripping works and drives the switch. reset, the power supply circuit is cut off at this time.
