Abstract
The utility model discloses a no-load energy saving device for an electric welding machine. The utility model is composed of a contactor, a timing relay and a voltage doubling rectification circuit. A wire package pack and a normally closed contact of the contactor are connected with the voltage doubling rectification circuit. A normally closed contact of the timing relay and the voltage doubling rectification circuit are connected in series and are assembled with a power supply to form a return circuit. Capacitance is connected between the contacts of the contactor in parallel. After a leading wire of an output terminal of the electric welding machine and the normally closed contact and a normally opened contact of the contactor are respectively connected with an adjustable resistance in series, the one output terminals of the electric welding machine and the contactor are connected in parallel and are connected with the timing relay; thus, a return circuit is formed. When the utility model is used for the electric welding machine of no load, the utility model has the advantages of electricity saving, safe work and low manufacture cost.
Description
What the utility model related to is a kind of electric welder no-load electricity-saving appliance.
At present, people are to more and more attention of electric welder no-load power consumption, taked several different methods to address this problem, what have adorns a primary source switch on soldering turret, because of the voltage height, easily get an electric shock dangerous, the pure electronic circuit that manufacturing that has and electric welding machine join is made this circuit cost height, complex circuit, inconvenient maintenance; What have makes to trigger power supply with the small transformers step-down, and service life is short, and effect is undesirable.
It is low that the purpose of this utility model is to provide a kind of electric welding machine to consume energy when zero load, the electricity-saving appliance of safe ready.
The purpose of this utility model is to realize like this, a circuit of forming by contactor, electrotimer, voltage doubling rectifing circuit in the power input setting of electric welding machine, line bag, normally-closed contact on the contactor link to each other with voltage doubling rectifing circuit, normally-closed contact on the electrotimer and voltage multiplying rectifier are connected in series and form an electric capacity in parallel between contact on loop, the contactor with power supply, and the output lead-in wire of electric welding machine and the normally-closed contact of contactor and normally opened contact are connected separately and be connected to form the loop to exporting an end and electrotimer side by side behind the adjustable resistance.
Good effect of the present utility model is embodied in this electricity-saving appliance and economizes electric energy in the electric welder no-load time, and safe ready is reliable in use, and is highly sensitive, contacts with ground wire as long as mention soldering turret, and the starting electric welding machine carries out work; Electrotimer disconnects when stopping using, and the line bag can not be worked, and contacts of contactor separately stops power supply to electric welding machine, and this electricity-saving appliance is the good equipment that a kind of power saving is safe and reliable, cost is low.
The utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a line map of the present utility model.
As can be seen from Figure 1, the line bag 4 on the contactor, normally closed melting point 5 link to each other with voltage doubling rectifing circuit 3, and the normally-closed contact 6 on the electrotimer is connected in series with voltage doubling rectifing circuit 3 and forms loop, 1 the parallel connection-electric capacity in the contact on the contactor; The normally-closed contact 8 of the output of electric welding machine T lead-in wire and contactor 1 and the normally opened contact 9 output one end in parallel formation loop that links to each other with the contact 2 of electrotimer of connecting separately behind the adjustable resistance.The power turn-on switch, power supply provides desirable starting current to start working through electric capacity and voltage multiplying rectifier to the line bag 4 on the contactor, impel normally closed interlock 5,8 disconnect, contact 1,9 adhesives, give the electric welding machine powered operation, if when quitting work, electrotimer regularly disconnects, make the normally-closed contact 6 on the relay 2 disconnect, can not provide starting current to line bag 4, normally-closed contact 5,8 restore to the original state, contact 1,9 disconnect, electric welding machine T quits work, and impels contact 2 adhesives on the electrotimer because of contact 1 electric capacity in parallel produces little electric current again, when the starting electric welding machine, with the discharge of joining of soldering turret and ground wire, electrotimer upper contact head 2 disconnects, and contact 6 adhesives simultaneously make electric welding machine work again.
