Abstract
The utility model relates to a socket with a monitor type automatic on-off supply unit. One plug bush of the socket is connected with the input terminal of a current transformer, the other terminal of the current transformer is connected with a commutation filtering circuit which is connected with a switching circuit, and the switching circuit is connected with a relay which can control the power signal of a subordinate electric appliance or an instrument. The utility model can overcome the problem that opening and closing the electric appliance or the instrument one by one in use bring a lot of inconvenience, and can avoid the harm from the opened electric appliance or the opened instrument; the utility model has the advantages of convenient operation, less time and high safety.
Description
The utility model is a kind of socket of switching electricity automatically.
Along with the development of society, one group of electrical equipment or the matching used situation of instrument are more and more general, as computer and its peripheral hardware.When people open or close electrical equipment or instrument; must electrical equipment or instrument on the same group be opened or closed one by one; safer also will pull up plug or the switch on the socket cut out; not only lost time but also certain electrical equipment or instrument had taken place easily and forgotten the situation of closing; if the electrical equipment of being forgotten to close lacks the function of self-protection, very likely lead to fire or cause the damage of electrical equipment (or instrument).
The purpose of this utility model provides a kind of main electrical equipment (or instrument) in one group of matching used electrical equipment (or instrument) and connects, other subordinate electrical equipment all can be switched on, when last was closed in the main electrical equipment (or instrument), other electrical equipment (or instrument) is the socket that has monitor-type auto switching supply unit of outage all.
The utility model comprises socket, a sleeve at the socket interpolation block links to each other with the input of current transformer, the other end of current transformer links to each other with a current rectifying and wave filtering circuit, current rectifying and wave filtering circuit links to each other with a switching circuit, and the relay that switching circuit and can be controlled subordinate electrical equipment (or instrument) power supply signal links to each other.
The utility model is used for one group of electrical equipment or the supporting use of instrument, and after one or several electrical equipment (being called main electrical equipment or instrument) of opening earlier or closing earlier opened or cuts out, remaining electrical equipment or instrument (being called subordinate electrical equipment or instrument) can switch on or disconnect automatically.The utility model has been avoided variety of issue and inconvenience that each electrical equipment or instrument open and close are one by one brought, saves time, and can avoid owing to forget the fire that powered-down causes and the infringement of electrical equipment or instrument.
Fig. 1 is the utility model embodiment circuit diagram.
Embodiment:
The utility model comprises socket, a sleeve 1 on the socket links to each other with the input of current transformer 2, the output of current transformer 2 links to each other with an end of a current rectifying and wave filtering circuit, current rectifying and wave filtering circuit comprises a rectifier bridge 3 that plays detection effect of being made up of four diodes, one end of resistance 4, electric capacity 5, voltage stabilizing didoe 6, resistance 7, rectifier bridge 3 links to each other with an end of resistance 4, the other end of resistance 4 links to each other with an end of electric capacity 5, voltage stabilizing didoe 6, resistance 7 respectively, and the other end of rectifier bridge 3 links to each other with the other end of electric capacity 5, voltage stabilizing didoe 6, resistance 7.The other end of current rectifying and wave filtering circuit links to each other with an end of a switching circuit, switching circuit comprises that 8 and rectifier bridges 9 that play rectified action of a VMOS pipe are composed in series, and the relay 10 that an end of rectifier bridge 9 and can be controlled subordinate electrical equipment or instrument power source signal links to each other.After the energized 11, when socket 1 (promptly main electrical equipment or instrument) is inserted in load, load current is by instrument transformer and produce induced voltage, through rectifier bridge 3 rectifications, resistance 4, electric capacity 5 filtered direct voltages are added on the VMOS pipe 8, after main electrical equipment (or instrument) is opened, when load current surpasses certain value, VMOS manages conducting, the node of relay 10 is by adhesive, be connected on the electrical equipment energising on the back socket 12, when the node disconnection of load (main electrical equipment or instrument) relay 10 when closing, the subordinate electrical equipment or the instrument that are connected on the back all cut off the power supply.
Claims (1)
