Secondary coil one end of described electric welding machine links to each other with soldering turret, and an end links to each other with workpiece, and the other end of described workpiece then connects together with ground.
One end of described AC relay links to each other with live wire, and the other end of described AC relay is connected successively with the normally-closed contact of the normally-closed contact of sensitive relay, the time relay, is connected on zero line side at last.
The normally-closed contact of described sensitive relay is in parallel with the normally opened contact of AC relay, is connected the described time relay between soldering turret and circuit ground, and the normally-closed contact of AC relay is connected with the coil of sensitive relay simultaneously, is connected between soldering turret and the circuit ground.
Control end one end of described solid-state relay links to each other with live wire, the other end is connected zero line side by the normally opened contact of AC relay, also be connected with the primary coil of auxiliary transformer at live wire and zero line side, and secondary coil one end of transformer is connected between the coil of the normally-closed contact of relay and sensitive relay by resistor, and the other end then links to each other with circuit ground.
The utlity model has following beneficial effect: the A.C. welder no-load automatic stop battery saving arrangement that the utility model provides has following advantage:
1), automatic powered-down when electric welding machine does not weld, allow electric welding machine that arranged enough cool times, so just prolonged the service life of electric welding machine.
2), with the conducting of solid-state relay with by the power down switch of making electric welding machine, replace the closure and the disconnection of mechanical switch, have contactless and beat, do not have that mechanical noise, Radio frequency interference are little, switching on and shutting down do not produce electric arc, advantage such as the fast and volume of switching speed is little.
3), the equipment self reactive loss seldom, the circuit elements device cost is cheap.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is the utility model structural representation.The utility model comprises master switch 1, electric welding machine 2, soldering turret 3, AC relay 4, it is characterized in that: described battery saving arrangement also comprises solid-state relay 5, and the output series connection of the primary coil of described electric welding machine 2 and solid-state relay 5 is at the live wire and the zero line side of alternating current.
Described electric welding machine 2 secondary coil one end link to each other with soldering turret 3, an end links to each other with workpiece 6, the other end of described workpiece 6 then connects together with ground.
One end of described AC relay 4 links to each other with live wire, and the other end of described AC relay 4 is connected successively with the normally-closed contact of sensitive relay 7, the normally-closed contact of the time relay 8, is connected on zero line side at last.
The normally-closed contact of described sensitive relay 7 is in parallel with the normally opened contact of AC relay 4, is connected the described time relay 8 between path that soldering turret 3 is connected with zero line and ground, and the normally-closed contact of AC relay 4 is connected with the coil of sensitive relay 7 simultaneously.
Control end one end of described solid-state relay 5 links to each other with live wire, one end is connected zero line side by the normally opened contact of AC relay 4, also be connected with the primary coil of auxiliary transformer 10 at live wire and zero line side, and secondary coil one end of transformer is connected between the coil of the normally-closed contact of AC relay 4 and sensitive relay 7 by resistor, and the other end then links to each other with circuit ground.
Be to realize operation principle of the present utility model below
1), start (to be welded)
2), work (welding work pieces)
When needs weld, as long as welding rod and workpiece are collided, sensitive relay 7 this in a flash will dead electricity and with its normally-closed contact closure, AC relay 4 gets electric, the normally opened contact closure of AC relay 4, solid-state relay 5 conductings, electric welding machine 2 is electricly elementary, promptly enters duty.Because the closed self-locking of the normally opened contact of AC relay 4, normally-closed contact disconnects: sensitive relay 7 still can get electric its normally-closed contact that makes and disconnect, and the normally opened contact of AC relay 4 still keeps adhesive.During electric welding machine 2 welding, its secondary voltage is generally less than or equals 35V, does not reach the requirement of the time relay 8 pick-up voltage 60V, the SJ akinesia, and welding job normally goes on always.
3), stop weldering (control is shut down automatically)
When welding rod leaves workpiece, when stopping to weld, electric welding machine 2 secondary voltages are elevated to 60V-80V at once, this voltage is greater than the pick-up voltage of the time relay 8, the time relay 8 adhesives are through certain hour, general adjusting time ratio changes the welding rod time when normally welding long, approximately be that 10-30 disconnected after second, cut off the wire loop of AC relay 4, solid-state relay 5 not conductings of no Continuity signal, at this moment since sensitive relay 7 already electric and in advance with the disconnection of its normally-closed contact, therefore solid-state relay 5 not conductings, electric welding machine 2 is cut off the electricity supply automatically, the normally-closed contact closure of AC relay 4, wait for and working next time that electric welding machine 2 is finished a work period circulation like this.When welding, circuit repeats said process again again.
