Abstract
The utility model discloses an air auto-power-off device of an electric welding machine welder. The air auto-power-off device resolves the burning-out phenomenon which is caused by reactive power and long-time power-on when a prior electric welding machine has no load. The utility model has the advantages of simple structure, convenient use, effective reduction of energy consumption, less error rate and the like. The utility model is characterized in that the air auto-power-off device comprises a welding transformer and a controlling switch, one end of the welding transformer is connected with one end of a control transformer in parallel via an alternating current contactor, and the end of the control transformer is also provided with a relay normally-opened contact which forms a return circuit together with the alternating current contactor, the other end of the welding transformer is connected with the other end of the control transformer in parallel via a normally-opened contact of the alternating current contactor, and then is connected with a welding gun, meanwhile, a relay is arranged at the other end of the control transformer.
Description
Technical field
The utility model relates to the control circuit of a kind of rivet welding with electric welding machine, relates in particular to a kind of electric welding machine air auto-power-off device.
Background technology
At present rivet welding can cause the reactive power of circuit excessive with electric welding machine its idle time when long, the waste of energy situation is more serious, and after welding machine works long hours, can produce very big heat, particularly during the broiling summer, welding machine energising for a long time can cause repeatedly welding machine to burn out the accident generation, and what influence was produced normally carries out.
Summary of the invention
The purpose of this utility model is exactly in order to solve reactive power that present electric welding machine produces when the zero load and the burnout phenomenon that causes of energising for a long time, provide a kind of have simple in structure, easy to use, can effectively cut down the consumption of energy, reduce the electric welding machine air auto-power-off device of advantages such as fault rate.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric welding machine air auto-power-off device, it has welding transformer and gauge tap, described welding transformer one end is in parallel with control transformer one end through A.C. contactor, and this end of control transformer also is provided with relay normally open contact, and it and A.C. contactor are formed a loop; The welding transformer other end through the A.C. contactor normally opened contact with connect welding gun after the control transformer other end is in parallel, this end of control transformer is provided with relay simultaneously.
The utility model adopts relay and A.C. contactor that original circuit is transformed, the gauge tap control transformer that closes before welding has, when welding rod contacts with workpiece one, the control transformer Secondary Winding is touched, and auxiliary reclay energising action, its normally opened contact closure, A.C. contactor action, its main contacts closure, electric welding machine are started working.The Secondary Winding of the Secondary Winding of control transformer and welding transformer is in closed state by the main contacts of A.C. contactor when stopping welding, because control transformer is in parallel during with welding machine, so the voltage phase isopolarity of Secondary Winding is identical thereby be added in that voltage on the relay coil equals zero, relay is threaded off and discharge its normally opened contact and open the A.C. contactor outage after by 30 wonderful time-delays, welding machine quits work.
The beneficial effects of the utility model are: improved circuit moment when the operative employee send electricity back, electric welding machine to be in off position, welding rod to contact with workpiece send electric welding machine work, when operating personnel after hours, welding machine no-load running cuts off the power supply after 30 seconds automatically, can effectively save electric energy; Also prolonged simultaneously electric welding machine service life, strengthened the safety utilization of electric power of producing.
