Description

The automatic reminiscences of powering

Technical field

The utility model relates to power system restoration power supply reminiscences, is suitable for power autonomous production user, particularly domestic consumer.

Background technology

At present because power shortages, often have a power failure, so that many production users and domestic consumer are power autonomous, with the solution need for electricity, but also bring some problems, power as power system restoration, if in time do not realize, just can not in time close power autonomously, cause economic waste, and generator continues discharging waste gas, noise continues contaminated environment, for this reason, no matter whether at night all will be careful every now and then daytime has restored electricity, make the user very awkward during power failure, the user who has has selected electric bell for use, electric light is as reminding indication, its weak point is: need during power failure manually electric bell or electric light to be connected circuit, when having restored electricity, after the prompting, need the people that they are disconnected, if have a power failure again, forgotten electric bell or electric light are connected circuit again, then lost the power supply reminding effect.

Summary of the invention

The purpose of this utility model is to solve above-mentioned weak point, and the automatic reminiscences that can remind automatically when restoring electricity and can stop automatically reminding is provided,

The purpose of this utility model can reach by following technical solution: the utility model is powered, and automatic reminiscences comprises sample circuit, delay time electrical equipment, control circuit, alert circuit, sample circuit connects control circuit, delay circuit, delay circuit output connects control circuit, control circuit connects alert circuit, and the city is electrically connected sample circuit, control circuit, alert circuit.

Sample circuit is by resistance R ₁, R ₂, diode D ₃, stabilivolt DZ1, capacitor C ₂Form, civil power is through resistance R ₁Step-down is by diode D ₃Rectification, C ₂Filtering, R ₂Input time delay circuit after current limliting, the DZ1 voltage stabilizing, delay circuit comprises by integrated circuit (IC) 1, resistance R ₃, R ₄, capacitor C ₃, C ₄Vibration, the frequency dividing circuit formed, the signal after the time-delay is from the Q end output of integrated circuit (IC) 1, through the diode D of serial connection ₄, resistance R ₆To control circuit, control circuit is by controllable silicon SCR, capacitor C ₁, diode D ₁, D ₂, relay J forms J, SCR, D ₂Be concatenated into loop, D with civil power ₁Coils from parallel connection of coils with J.

Alert circuit 4 comprises alert circuit 5, external light alert circuit 6, the contact K of relay J _1-1, K _1-2Be serially connected in respectively on external light alert circuit 6, the sound alert circuit 5.

The utility model advantage: can remind automatically during service restoration and can stop automatically reminding.
