[description of drawings
Fig. 1 is a theory structure schematic block diagram of the present utility model.
[specific embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises electric welding main frame, switch, A.C. contactor, overload-alarm module, transformer, temperature protector; Described sound and light alarm module comprises analog-digital converter, single-chip microcomputer, display screen, audible and visible alarm lamp, and described audible and visible alarm lamp, amplifying circuit, analog-digital converter, single-chip microcomputer, display screen are electrically connected; One end of described A.C. contactor is connected with switch, and the other end is connected with temperature protector with transformer respectively, and described transformer is connected with temperature protector, A.C. contactor and analog-digital converter respectively; Described transformer provides power supply for electric welding main frame and single-chip microcomputer.Switch is the locking press button switch.
Described switch passes through the break-make of the work realization of control A.C. contactor to the input power supply of transformer; temperature protector is by surveying the desired temperature of transformer; digital to analog converter is accepted the electric current of transformer output, and magnitude of voltage also converts data signal to and handles the back via single-chip microcomputer and carry out numeral demonstration by display screen.
Single-chip microcomputer can connect a long-range cue emitter, when carrying out sound and light alarm, can also carry out long-range prompting, and receiving system can be the mobile phone or the computer of project supervision side.
Amplifying circuit between audible and visible alarm lamp and the analog-digital converter, purpose are the audio visual effects that strengthens the audible and visible alarm lamp.
During use, the utility model can show by the sound and light alarm lamp whether the transformer of electric welding machine is in running order, when the sound and light alarm lamp starts, shows that electric welding machine is in overheated power-off protection state.
The utility model can intuitively, accurately show actual operating current and operating voltage in electric welding machine work; when temperature protector can reach setting value in the operating temperature of transformer; by the outage of control A.C. contactor; avoid burning out with the protection transformer; by the time when temperature is reduced to the normal working temperature scope of transformer; automatic recovery of power supply makes electric welding machine drop to minimum because of the probability of overheated burning.
It should be noted that when the sound and light alarm lamp of electric welding machine starts, do not need to cut off the electricity supply that when treating that temperature is reduced to the normal working temperature scope of transformer (about 5 minutes), A.C. contactor can automatic recovery of power supply.
Because single-chip microcomputer can also connect a long-range cue emitter, when electric welding machine is in overheated power-off protection state and carries out sound and light alarm, can also carry out the remote information prompting, receiving system can be the mobile phone or the computer of project supervision side.Good looking appearance of the present utility model reads voltage, current value is accurate, and the technical performance of complete machine is perfect, and strong operability is safe, is adapted at applying in all kinds electric welding machine.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
