Abstract
The utility model relates to a power consumption free servo device for the electric appliance, which is composed of a working power supply, a pneumatic switch, a power supply circuit switch, a main contact control mechanism, and a current detecting circuit. The pneumatic switch is connected with the working power supply, the working power supply is switched in the main contact control mechanism, the current detecting circuit is switched into the alternating current circuit and electrically connected with the main contact control mechanism, and the main contact control mechanism controls the on-ff of the power supply circuit switch. After the electric appliance is shut down, the current decrease of the circuit is detected through the current detecting circuit, the main contact control mechanism is indicated to cut off the power supply circuit switch, and the electric appliance is safely cut off in far distance, simultaneously, the working power supply is also cut off, the purpose that all the components are cut off can be realized, and the electric energy consumption can be saved.
Description
Technical field
The utility model relates to a kind of electric switch controller, more particularly, and particularly a kind of non-power consumption servo apparatus of thorough cut-out appliances power source.
Background technology
Along with science and technology development, electric equipment has entered huge numbers of families.Such as devices such as host computer, display, printer, scanners, can quit work by after the computer operating system shutdown after the use, but these settings this moment still link to each other with power supply, power supply and incomplete cut-off, in fact also be in a kind of servo holding state, cause electric energy in various degree to expend.Computer equipment can make troubles to the user and manually pull out, insert plug because long-term charged standby influences its usability and serviceable life, and lightning protection effect is poor.The design operation inconvenience of the servomechanism installation control of prior art.
The utility model content
The purpose of this utility model is in order to overcome the deficiency that above-mentioned technology exists, and a kind of servomechanism installation of controlling simple, processing ease, making electrical equipment shutdown back no standby power and standby safety hidden danger is provided.
In order to achieve the above object, the utility model mainly adopts this technical scheme: a kind of electric appliance without power consumption servo device, comprise working power, pneumatic switch and power circuit switch, pneumatic switch is electrically connected with working power, also comprises main contacts control gear and current detection circuit, described main contacts control gear cut-in operation power supply, described current detection circuit inserts the mains circuit and the main contacts control gear is electrically connected, the break-make of described main contacts control gear control power circuit switch.
The break-make of the main contacts control power circuit switch of described main contacts control gear.
Compared with prior art, the utility model is owing to be provided with main contacts control gear and current detection circuit, after the electrical equipment shutdown, the electric current that current detection circuit detects circuit diminishes, and indication main contacts control gear deenergization line switching disconnects the remote safety of electrical equipment, simultaneously, working power also disconnects, and reaches the purpose that all components and parts are in off-position fully, saves power consumption.After the electrical equipment shutdown, need not the personnel tracking check circuit and whether disconnect, fully automatically control.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is the circuit theory diagrams of electric control on the working power;
Fig. 3 is the circuit theory diagrams of main contacts control.
Embodiment
Below in conjunction with most preferred embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, servomechanism installation is built in the body of socket, and it is made up of working power 4, power circuit switch 1, pneumatic switch 3, main contacts control gear 2, current detection circuit 5.Electrical equipment 6 inserts 220V civil power work and by being subjected to 1 control of power circuit switch.Working power 4 also inserts the 220V civil power, and it is subjected to pneumatic switch 3 controls, and gives the main contacts control gear 2 power supplies.The break-make of main contacts control gear 2 control power circuit switches 1, thereby the whether energising of control apparatus 6 power supplys.Be connected current detection circuit 5 between line and the main contacts control gear 2, when the current values that detects line changes and is lower than the numerical value of setting, send trigger pip, make 2 actions of main contacts control gear, thus the break-make of control power circuit switch 1.
Principle of work of the present utility model is as follows: at first, press pneumatic switch 3, working power 4 is from the line power taking, and to 2 power supplies of main contacts control gear, main contacts control gear 2 control power circuit switches 1 closure makes electrical equipment 6 energized operate as normal.At this moment, if press pneumatic switch 3 once more, main contacts control gear 2 can repetitive operation.
When closing electrical equipment, the current values on mains-supplied road diminishes, the numerical value that current detection circuit 5 detects electric current changes, if promptly compare when exceeding certain limit with the value of setting, current detection circuit 5 judges that electrical equipment 6 is in off working state, then send the off line signal, main contacts control gear 2 control power circuit switches 1 disconnect, and power circuit disconnects back working power 4 and also disconnects.
In addition, when starting electrical equipment 6, if successfully do not open in the time of setting, the current values that current detection circuit 5 detects the mains-supplied road is lower than setting value, can think that also electrical equipment 6 is in off-mode, thus deenergization.
Shown in 2, after pressing pneumatic switch, the AC portion of working power obtains power supply, and utilizes the normally opened contact of relay R EL1 to keep its power supply.When main electrical appliance quit work reach certain hour after, the main contacts control gear disconnects main contacts, and release relay, and working power is stopped power supply.
As shown in Figure 3, current transformer is received in the main line, is used to detect the electric current of main electrical equipment actual consumption.When electric current less than predetermined value, just can think that main electrical equipment has quit work.Single-chip microcomputer is used to gather the current signal of current transformer, and the control direct current generator just/the reverse turn direct current generator drives the motion of main contacts topworks, realize the closed of main contacts or disconnect.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make many forms, these do not have substantial change and all belong within the protection of the present utility model.
