Abstract
The invention provides a no-load energy-saving method of a three-phase DC electric welding machine. Electrical elements installed in the circuit of the DC electric welding machine include a normally open button switch SB1, an AC contactor KM, an overvoltage relay KV, a time relay KT and a normally closed button switch SB2; the normally open button switch SB1 is used for closing the control circuit of the electric welding machine so that the AC contactor KM is powered on to work; the AC contactor KM is used for controlling on and off of the primary coil of the transformer circuit BX of the electric welding machine; the overvoltage relay KV is connected in parallel to the secondary side of the transformer circuit BX of the electric welding machine and used for controlling on and off of the time relay KT. The no-load energy-saving method of the three-phase DC electric welding machine has the beneficial effect of saving energy when the electric welding machine is no-load.
Description
Technical field
The present invention relates to a kind of three-phase dc electric welder no-load power-economizing method, belong to field of mechanical technique.
Background technology
Existing three-phase dc electric welding machine is still powered to electric welder transformer during stopping weldering, and waste of energy is serious.How can when electric welding machine not being carried out the large change of overall structure, reducing the situation of waste of energy, is the problem that the present invention will study.
Summary of the invention
The invention provides a kind of three-phase dc electric welder no-load power-economizing method, when electric welder no-load, energy-conservation beneficial effect can be played.
For solving above technical problem, the invention provides following technical scheme: a kind of three-phase dc electric welder no-load power-economizing method, the electric original paper installed in dc welding machine circuit comprises making button switch S B1, A.C. contactor KM, overvoltage relay KV, time relay KT, dynamic circuit breaker press button SB2, making button switch S B1 starts control circuit of electric welding machine, makes A.C. contactor KM obtain electric work; A.C. contactor KM is for controlling the break-make of electric welder transformer circuit BX primary coil; Overvoltage relay KV is connected in parallel on the secondary of electric welder transformer circuit BX, for the break-make of control time relay K T; Time relay KT is for regulating the electric welder no-load duration; Dynamic circuit breaker press button SB2 makes A.C. contactor KM dead electricity quit work, for immediately closing electric welder control, during work, press making button switch S B1, contactor KM adhesive, electric welder transformer circuit BX primary coil obtains electric, and electric welding machine is started working, and normally carries out weld job, now voltage is lower, overvoltage relay KV disconnects, and time relay KT quits work, and welding process is carried out continuously; When suspending weld job, overvoltage relay KV obtains electric adhesive under floating voltage, and time relay KT is energized, and time delay process starts, and is no more than the setting time of time relay KT in interval idle time, and welding is carried out continuously; The idle time of electric welding machine exceedes setting time, and the normally-closed contact of time relay KT disconnects, and contactor KM power-off is discharged, thus closes electric welding machine input power.
Further, close electric welding machine input power immediately by pressing dynamic circuit breaker press button SB2 at any time, making button switch S B1, dynamic circuit breaker press button SB2 are arranged on electric welding machine guidance panel or are arranged on electric arc welding clamp WP.
This three-phase dc electric welder no-load power-economizing method that the present invention relates to, rational in infrastructure, method is simple, the feature of stable work in work, it wastes and is only about 1/10 of usual products, saves production cost 30%, therefore, the application of this technology has good economic benefit, realizes product industrialization, meets the Times ' Demand of environmental protection.
