Abstract
The utility model mainly discloses an energy-saving controller based on a single chip microcomputer. The energy-saving controller comprises the single chip microcomputer, an optical coupler and an output relay, wherein the optical coupler of a direct current circuit connected with a welding machine is connected with the single chip microcomputer, and the output relay is connected at a control end of the single chip microcomputer, and simultaneously connected to a contactor of the welding machine. The energy-saving controller can timely shut down a main power supply when a three-phase direct current welding machine does not work so as to achieve the aim of saving energy, and can timely switch on the main power supply when welding operation is on so as to ensure normal welding.
Description
Technical field
The utility model relates to a kind of energy-saving controller, and is relevant especially for a kind of SCM Based energy-saving controller of three-phase direct current-direct current (AC-DC) welding.
Background technology
At present, the welding machine energy-saving controller of selling on the market, based on the control AC welding set, and the repacking of controller need install contactor, control electronic box or outside microswitch additional, and still blank in this field of three-phase dc welding machine energy-saving controller.
With ZX5-1000 direct current gouge welding machine is example, and welding machine because continue in power supply the welding machine primary circuit, records about welding machine no-load current 9-12A this moment, according to power when not using
Calculate P=380 * 12 * 1.732 * 0.86=6792.21W, when this welding machine is unloaded so per hour with 6.8 kilowatts of power consumptions.Suppose that gouge started shooting 20 hours every day, but may being to use 5 minutes when carrying out the gouge operation, reality stopped 5 minutes or stopped the longer time, because the workman generally can be when not coming off duty switch welding machine back and forth, the one, trouble two is to waste time, gouge just has at least 10 hours no-load running time so, and 10h * 6.8kw=68kw calculates by average 1 yuan of the electricity charge/degree, at least every day, every gouge can be wasted 68 yuan of electricity charge, wasted very serious.
Gained to sum up, the average gouge working time generally can not surpass 50% of the on time, and the no-load ratio of welding machine is 50% at least just so.So the utility model is exactly the real work machine time of effectively controlling welding machine, reaches energy-conservation purpose.
The utility model content
The purpose of this utility model is to provide a kind of SCM Based energy-saving controller, can in time close primary power when the three-phase dc welding machine is not worked, and to reach energy-conservation purpose, can in time connect primary power when weld job is arranged, and guarantees normally welding.
To achieve these goals, solution of the present utility model is:
A kind of SCM Based energy-saving controller, comprising will be by single-chip microcomputer, photo-coupler, output relay; The DC circuit photo-coupler that connects welding machine links to each other with single-chip microcomputer, and output relay is connected the control end of single-chip microcomputer, receives the welding machine contactor simultaneously.
It is the single-chip microcomputer power supply that described single-chip microcomputer becomes the 5V power supply by the AC6-24V of welding machine internal control transformer control power supply through the mu balanced circuit rectifying and wave-filtering.
Described single-chip microcomputer inside is provided with time block, and the detected welding machine AC signal of photo-coupler starts time block, the break-make of time block control output relay.
After adopting such scheme, the utility model can become welding signal with the alternating current-direct current signal transition of three-phase dc welding machine, detects and send to single-chip microcomputer by photo-coupler, produces control signal by single-chip microcomputer, the work of the closed and disconnected control welding machine of output relay.So just welding machine in time may cut out primary power when the zero load, to reach energy-conservation purpose, effectively energy-conservation up to 50%.
Single-chip microcomputer power supply simultaneously of the present utility model does not need to increase additional power supply directly by the power supply of welding machine internal control power supply, and simple in structure, power supply is stable, and cost is low.And module when setting in single-chip microcomputer, in setting-up time, do not detect the welding machine working signal like this, just close primary power, prevent the error operation, make control have more intellectuality.In addition, adopt Single-chip Controlling can change internal processes at any time to reach different welding machine control purposes, control flexibly.
Description of drawings
Fig. 1 is the circuit diagram of the utility model preferred embodiment.
Embodiment
In conjunction with the accompanying drawings, the utility model is described in further details.
A kind of SCM Based energy-saving controller, comprising will be by single-chip microcomputer 1, photo-coupler 2, mu balanced circuit 3, output relay 4.
Single-chip microcomputer 1 is picked out by the control power supply of welding machine internal control transformer, carries out rectifying and wave-filtering through mu balanced circuit 3, AC6-24V is controlled power source transition become the 5V DC voltage, is single-chip microcomputer 1 power supply.
Photo-coupler 2 is external to the DC circuit of welding machine, and the output terminal of photo-coupler 2 connects single-chip microcomputer 1.Output relay 4 is connected the control end of single-chip microcomputer 1, and output relay 4 is received the contactor of welding machine simultaneously, passes through the pin 1 of interface CON6 and the contactor of pin 2 outer welders in the present embodiment.
Single-chip microcomputer 1 has or not welding current according to the control program operation that writes by photo-coupler 2 detections during the utility model work, if there is welding current will make output relay 4 keep output.In the present embodiment, single-chip microcomputer 1 inner setting has time block, if in the time range of setting 10 seconds to 300 seconds, will not turn-off output relay 4 if detect welding current.When weld job again, welding rod detects welding signal as long as contact by photo-coupler 2 with workpiece, single-chip microcomputer 1 output signal is connected output relay 4, because single-chip microcomputer 1 reaction velocity is 2us, so can not feel to have delay phenomenon, welding rod can carry out weld job as long as contact with workpiece.
