It includes knife switch, fuse, auxiliary relay, ac contactor, time relay, condenser, electric welding and contact. Time relay and auxiliary relay mutually support, and the operating condition of in good time supervision electric welding is according to the operating condition of electric welding, ac contactor will be in time automatic switching power. In the time will welding, only need according to normal welding operation, welding rod and weldment short circuit once, but switch on just makes welding machine entering normal operating conditions, time relay when stopping to weld 1 export the instruction of stopping power supply behind the 60s, ac contactor will break off working power supply in good time.
Description
Technical field
The utility model belongs to energy-saving safety controller, specifically a kind of energy-saving safety controller of electric welding machine.
Background technology
Very big at ore deposit brand-name computer repair shop monthly welding processing task amount, the oepration at full load the most everyday of multiple stage electric welding machine.Electric welding machine in use, due to welding personnel want butt-welding fitting to be adjusted, scarfing cinder or temporarily change factors such as doing other work, cause electric welding machine to be usually in no-load standby state.Cause substantial amounts of electric energy to waste during no-load running, add production cost.Additionally, secondary side output voltage is about 60～70V during electric welder no-load, non-security voltage, accidentally touch exposed band point metal during operation and be easy for causing the generation of electric shock accidents, there is potential safety hazard.
To this end, for above safety problem, through repeatedly inquiring into, design and putting into practice, design completes energy-saving safety controller of electric welding machine.
Summary of the invention
For the deficiency overcoming prior art to exist, the utility model provides a kind of energy-saving safety controller of electric welding machine reasonable in design.
The utility model realizes above-mentioned purpose by the following technical solutions:
A kind of energy-saving safety controller of electric welding machine, it includes knife switch, fuse, auxiliary reclay, A.C. contactor, the time relay, capacitor, electric welding machine and contact.
Described electric welding machine to power supply by connection, the circuit between electric welding machine and power supply is connected and has knife switch；A wherein circuit between described knife switch and electric welding machine is provided with contact and has a capacitor with this contact shunt；Auxiliary reclay and A.C. contactor it is parallel with on circuit between described capacitor and knife switch；It is connected to contact on described auxiliary reclay and A.C. contactor；Described auxiliary reclay and the parallel circuit of A.C. contactor are provided with fuse；Described electric welding machine is provided with the time relay；Three contacts in circuit are respectively the node of A.C. contactor, auxiliary reclay and the time relay.
The described time relay cooperates with auxiliary reclay, and the in good time duty monitoring electric welding machine, according to the duty of electric welding machine；Described A.C. contactor is by auto switching electric source in time.When time to be welded, only need to operate by normal weld, welding rod and weldment short circuit are once, so that it may switch on power, and make welding machine enter normal operating conditions；The described time relay exports, after the 1-60s when stopping welding, instruction of stopping power supply, and A.C. contactor will disconnect working power in good time.
The utility model uses technique scheme to have the advantages that
The utility model can achieve over the operation of 1-60 second welding, automatically cuts off welding machine primary side power supply, reduces the welding machine no-load running time, and no-load saving rate is up to more than 98%.Sensitivity is adjustable, is suitable for varying environment and the operation of different model electric welding machine.Automatically cutting off electric welding machine primary power source during no-load saving, secondary idle load voltage is less than 36V, it is to avoid the generation of operating personnel's accidental shock accident.The potential safety hazard that operator is likely to result in injury is especially thoroughly solved from technological layer.In implementation process, obtain good effect, there is reasonable generalization.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is described further.
A kind of energy-saving safety controller of electric welding machine as shown in Figure 1, it includes that knife switch 1, fuse 2, auxiliary reclay 3, A.C. contactor 4, the time relay 5, capacitor 6, electric welding machine 7 and three contacts, three described contacts are respectively the first contact 83, the 81, second contact the 82, the 3rd, contact.
Described electric welding machine 7 to power supply by connection, the circuit between electric welding machine 7 and power supply is connected and has knife switch 1；A wherein circuit between described knife switch 1 and electric welding machine 7 is provided with the first contact 81 and is parallel with a capacitor 6 with the first contact 81；Auxiliary reclay 3 and A.C. contactor 4 it is parallel with on circuit between described capacitor 6 and knife switch 1；The second contact 82 and the 3rd contact 83 it is connected on described auxiliary reclay 3 and A.C. contactor 4；Described auxiliary reclay 3 and the parallel circuit of A.C. contactor 4 are provided with fuse 2；Described electric welding machine 7 is provided with the time relay 5；Described the 81, second contact, the first contact 82 and the 3rd contact 83 are respectively A.C. contactor 4, auxiliary reclay 3 and the node of the time relay 5.
Close knife switch, and auxiliary reclay obtains electric, then node the 3rd closing of contact of auxiliary reclay；A.C. contactor is energized, then node first closing of contact of A.C. contactor, makes electric welding machine obtain electric；The time relay is energized, then node second contact of the time relay obtains electric time delay disconnection.
When the electric welding machine not used time, between time relay delay arrival time, then node second contact of the time relay disconnects；Auxiliary reclay power-off, then node the 3rd contact of auxiliary reclay disconnects；A.C. contactor power-off, then node first contact of A.C. contactor disconnects；Capacitor turns on electric welding machine, have the electric current of smile hold time relay work.Second short circuit when soldered, the time relay does not has electricity, then the time relay node Guan Bi, electric welding machine again electric.
After installing this controller additional, the floating voltage of electric welding machine secondary output is generally not more than 36V, belong to essential safety voltage, even if operator directly touches welding machine secondary side exposed charged metal body and also do not results in electric shock injury, thoroughly solve the potential safety hazard that operator is likely to result in injury from technological layer.
