The electrolytic capacitor C2 plays a role in filtering the high level output by the emitter of the NPN triode Q5.

As shown in fig. 2, in the control circuit and the communication circuit: when the electric equipment is overloaded, the input power supply voltage is overhigh, the input power supply voltage is overlow or the power failure occurs, the relay J2 is electrified to attract the control power supply input end and the normally open contact end of the relay J2 to be closed, because the normally open contact end of the relay J2 is connected with the positive power supply input ends of the relay J1 and the relay J3, the negative power supply input end of the relay J2 is connected with the negative power supply input end of the relay J1, the control power supply input end and the negative power supply input end of the third relay J3 are grounded, at the moment, the control power supply input end and the normally open contact end of the relays J1 and J3 are electrified to be; because the normally open contact end of the relay J1 is connected with the signal input end X of the communication module U through a lead, and the negative power input end and the control power input end of the relay J1 are grounded, when the electric equipment load is too large, the input power voltage is too high, the input power voltage is too low or power failure occurs, the relay J2 is electrified to attract the control power input end and the normally open contact end to be closed, at the moment, the signal input end X of the communication module U is input with a low level trigger signal, so under the action of an internal circuit of the communication module U, the communication module U can automatically send out the pre-stored short message through a mobile network, the content of the short message is 'abnormal electricity utilization of the electric equipment', when the electricity utilization voltage is over high, the electricity utilization voltage is too low or the electricity utilization load is too large in the communication module U, one or more telephone numbers of users and managers needing to be notified receive the short message, the user or the manager can know that the power utilization fault of the power utilization equipment occurs at the first time, so that the user or the manager can arrive at the site at the first time to take countermeasures after receiving the short message. Because the relay J3 controls the power input end and the normally open contact end to be respectively connected with the two power contacts under the leakage experiment button SK of the leakage protector U1 through the leads, the power input end of the electric equipment M is connected with the input power through the leakage protector U1, therefore, when the electric equipment is overloaded, the input power supply voltage is overhigh, the input power supply voltage is overlow or power failure occurs, the relay J2 is electrified to pull the control power supply input end and the normally open contact end of the relay J2 to be closed, the two power contacts under the leakage experiment button SK of the leakage protector are communicated, and then, under the function of the leakage protector U1, the leakage protector U1 trips, the electric equipment M stops using electricity, therefore, the electric equipment is effectively prevented from working under the condition of overhigh or overlow voltage and from being damaged due to the fact that the electric equipment works under the condition of overlarge input power supply load caused by self faults of the electric equipment.
