Description

Low-voltage remote-control voltage regulator

The utility model belongs to voltage adjuster, is a kind of improvement about common low pressure remote-controlled system configuration.

The remote control voltage regulator that uses both at home and abroad has the wireless remotecontrol voltage regulator at present, infrared remote control voltage regulator, the silicon-controlled voltage regulation system of band remote-control box, bulb or Remote controlling system for electric appliances etc.Bulb or Remote controlling system for electric appliances are a kind of common low pressure remote-controlled systems, generally are made up of regulator and remote control switch, as shown in Figure 1, introduce the bulb or the Remote controlling system for electric appliances of the U.S. for the electronic circuit encyclopedia.It adopts the structure of bidirectional triode thyristor, transformer, control utmost point adjustable resistance, electrical appliance socket and switch, feeder line.The principle of this bulb or Remote controlling system for electric appliances is: civil power is added to the two ends of transformer and bidirectional triode thyristor control utmost point adjustable resistance branch road and bidirectional triode thyristor by electrical appliance, when the remote control switch that is positioned at the secondary side of transformer low voltage does not close, has only very little no-load current on primary coil and the adjustable resistance.The pressure drop of this electric current on adjustable resistance is not enough to trigger bidirectional triode thyristor, so not conducting, electrical appliance is not worked, when remote control switch closes, transformer secondary output short circuit, the saturation current of its primary coil make the pressure drop on the control utmost point adjustable resistance meet or exceed the bidirectional triode thyristor trigger voltage, the controllable silicon conducting, electrical appliance powers up work, and at this moment transformer is bordering on and does not work.Change the adjustable resistance resistance, can carry out the voltage adjustment.Because the remote control switch of this class bulb or Remote controlling system for electric appliances and adjustable resistance are lived apart in the both sides of transformer, thereby have following shortcoming: (1) has only a kind of remote control of on-off mode, can not carry out Regulation Control at a distance; (2) can not connect with the controller of various ways such as acoustic control, light-operated, time control, function singleness, (3) control utmost point adjustable resistance connects civil power in electrical appliance one side, and pressure regulation was both dangerous, and was inconvenient again.

At the shortcoming of above remote control system, the purpose of this utility model is that a kind of improved low pressure remote-controlled voltage regulator will be provided.It not only can realize the remote control of switch and pressure regulation, directly control, but also can connect with the various control device easily, realizes multifunction remote-control, has characteristics such as easy to use, the scope of application is big, safety.

The utility model is finished as follows: on transformer low voltage is secondary and a socket, having by the plug feeder line that matches with it can switch, the remote controller of Regulation Control.Display, remote-control box that control piece, light-emitting diode and the dropping resistor that this remote controller is made of a switch and the adjustable device series connection of resistance constitutes are formed.When the control of remote controller switch did not close, the electric current on the transformer was very little, and controllable silicon ends, and electrical appliance is not worked, and light-emitting diode is bright; When above-mentioned switch closed, big electric current was flowed through on primary coil and the control utmost point adjustable resistance, the controllable silicon conducting that is triggered, thus civil power is added on the electrical appliance, and light-emitting diode goes out.Here, the light and shade of light-emitting diode can directly indicate the state of a control of control piece.Change the adjustable device resistance of resistance in the control piece, promptly change the size of transformer load, can change the size of current of flow through primary coil and adjustable resistance.When a certain point voltage value reaches the controllable silicon trigger voltage in the voltage waveform on adjustable resistance, the controllable silicon conducting that is triggered.Therefore the adjustable device resistance of resistance can directly influence the silicon controlled angle of flow in the control piece, thereby plays the pressure regulation effect.When needs are controlled by other controllers such as acoustic control, light-operated, time controls, as long as just can at the plug of other controllers of socket place changing-over.In addition, transformer secondary output by above-mentioned socket another contact pin and socket contact pin two ends and connect with remote controller in same control piece and display so that disconnect with being connected of remote controller after can directly carry out the control of switch and pressure regulation.

The advantage of this low pressure remote-controlled voltage regulator is: (1) can realize remote control or directly control to switch and pressure regulation, satisfies user's instructions for use; (2) can connect with various control devices such as light, sound, time controls, the scope of application is wide; (3) the equal and mains isolation of control element, under low pressure operation is safe and reliable; (4) utilize plug connector, dismounting, changing-over are rapid, easy to use.
