Description
Technical field
The present invention relates to a kind of energy saver, specifically relate to a kind of energy saver of electric welding machine.
Background technology
A.C. welder is one of a kind of indispensable soldering appliance at construction site, but in the underground project dug underground uses such as subway, heating pipeline, electric power tunnel and people's air defense of reality, because the main material in the construction is a large amount of work such as reinforcing bar bow member, net sheet and metallic conduit welding, all there is every day tens electric welding machine to work simultaneously, in electric welding work, from weld one weld seam to welding next during to weld seam, often to do a lot of auxiliary work.At this moment electric welding machine just is in the no-load running state, still has no-load current to flow through in the elementary winding of electric welder transformer, and the workman has a meal or comes off duty and forgets and turn off power supply sometimes.Like this, just waste many electric energy.Idle time of electric welding machine even surpassed the operating time, its open circuit loss is generally about about 200w.This has not only wasted many electric energy, also can reduce the power factor of electrical network, even can cause personal electric shock casualty accident.
Because electric welding machine is the big equipment of power consumption, electric welding machine is energy-conservation can to bring considerable economic profit to enterprise, but also can alleviate power tense.And present most electric welding machine energy saver is all from improving the angle of power factor, and the effect of this raising is limited.
Summary of the invention
The purpose of this invention is to provide the high electric welding machine energy saver of a kind of energy-saving efficiency.
For achieving the above object, the present invention is by the following technical solutions:
The present invention is provided with power switch on the electrode holder of electric welding machine, power switch is connected in series with power supply, wireless transmitter module successively; On the welding machine of electric welding machine, wireless receiving module is set, wireless transmitter module and wireless receiving module wireless connections; Described wireless receiving module is connected with relay, and the relay normally open linked switch is connected on the welding machine electric power line.
Described wireless receiving module passes through mu balanced circuit, filter circuit and transformers connected in parallel at welding machine electric power line two ends.
Described relay also is provided with relay normally open contact, and relay normally open contact is connected in parallel on welding machine electric power line two ends.
Adopt the present invention of technique scheme, simple in structure, as long as components and parts are welded on the patch bay, and need not to use printed circuit board, can success.As long as turn off the power switch on the welding clamp handle conveniently, can realize the power save circuit of cutting off the power supply.And in practical operation, obtained good electricity-saving effect.Be characterized in: low in energy consumption, easy to operate, action is simple and direct, sensitive reliable, practical.This circuit is obtained good electricity-saving effect through using.By every day every welding machine save the several years electricity and calculate, several tens electric welding machines will be saved more than the degree electricity up to ten thousand in 1 year, the electric power energy that the unit's of can be saving is a large amount of, and can improve the power factor etc. of system when most of electric welding machine is stopped using.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present invention.
The specific embodiment
As shown in the figure, the present invention is provided with power switch K3 on the electrode holder of electric welding machine, and power switch K3 is connected in series with power supply VCC, wireless transmitter module 1 successively.Wireless receiving module 2 is set, wireless transmitter module 1 and wireless receiving module 2 wireless connections on the welding machine of electric welding machine.Wherein, wireless transmitter module and wireless receiving module are technology well known to those of ordinary skill in the art.
Above-mentioned wireless receiving module 2 is connected with relay J, and relay normally open linked switch K2 is connected on the welding machine electric power line.In addition, for prolonging the reaction time between relay J and the relay normally open linked switch K2, relay J also is provided with relay normally open contact K1, and relay normally open contact K1 is connected in parallel on welding machine electric power line two ends.Like this, when relay J get electric after, relay normally open contact K1 is at first closed, after the elapsed time postponed, relay normally open linked switch K2 got electric closure.
Need to prove that also wireless receiving module 2 is connected in parallel on welding machine electric power line two ends by mu balanced circuit, filter circuit and transformer T.Wherein, mu balanced circuit adopts three-terminal voltage-stabilizing chips W Y, and the model of three-terminal voltage-stabilizing chips W Y is 7812, and filter circuit adopts current rectifying and wave filtering circuit D and capacitor C.
Operation principle of the present invention is:
The 380V civil power changes 12V voltage into by transformer T, and this 12 voltage gives wireless receiving module 2 power supplies through the filtering of current rectifying and wave filtering circuit D and capacitor C, the pressure stabilization function of process three-terminal voltage-stabilizing chips W Y.
When the welder need weld, closure was positioned at the power switch K3 on the electrode holder 3, and after circuit was connected, power supply VCC gave wireless transmitter module 1 power supply, and wireless transmitter module 1 is started working and sent a signal to wireless receiving module 2.When wireless receiving module 2 is started working, make relay J get electric work, afterwards relay normally open contact K1 at first electric closure, postpone a period of time after relay normally open linked switch K2 get electric closure, welding machine 4 must be established beginning work by cable like this.
When the welder did not need electric welding machine work, the welder disconnected power switch K3 on the electrode holder 3, and this moment, wireless transmitter module 1 was not worked, so wireless receiving module 2 is not worked yet, relay must not be electric, and welding machine is not worked.
