Description
Technical field
This utility model relates to A.C. welder, specifically a kind of A.C. welder energy-saving control circuit.
Background technology
A.C. welder is the soldering appliance that industrial and mining establishment are conventional.When using A.C. welder to carry out weld job, by
In the impact (such as workman needs put workpiece or be busy with other affairs) of various factors, workman is not often closing power supply
In the case of stop weld job temporarily, cause A.C. welder to be in Light Condition.Zero load is there is yet with A.C. welder
The feature that loss is big, power factor is low, once A.C. welder is in Light Condition, certainly will cause huge waste of energy, by
This is greatly improved the operating cost of enterprise.Based on this, it is necessary to invent a kind of brand-new A.C. welder energy-saving control circuit, with
Solve A.C. welder and be in the problem that Light Condition causes huge waste of energy.
Summary of the invention
This utility model is in, in order to solve A.C. welder, the problem that Light Condition causes huge waste of energy, it is provided that
A kind of A.C. welder energy-saving control circuit.
This utility model adopts the following technical scheme that realization:
A kind of A.C. welder energy-saving control circuit, including air-break, catalyst, the first transformator, the second transformation
Device, commutator, three terminal regulator, TWH8778 high speed electronic switch, microswitch, resistance, the first electric capacity, the second electric capacity, the 3rd
Electric capacity；
Wherein, two inputs of the first transformator pass sequentially through the normally opened main contact of catalyst, air-break respectively
It is connected with two ac power input ends；Two inputs of the second transformator by air-break respectively with two alternating currents
Source input connects；Two outfans of the second transformator are connected with two inputs of commutator respectively；Commutator the most defeated
Go out end to be connected with the input of three terminal regulator；The outfan of three terminal regulator and the input of TWH8778 high speed electronic switch
Connect；The outfan of TWH8778 high speed electronic switch is connected with the negative output terminal of commutator by the coil of catalyst；
One end of microswitch is connected with the triggering end of TWH8778 high speed electronic switch, and the other end passes through resistance and three ends
The outfan of manostat connects；The two ends of the first electric capacity are connected with positive output end and the negative output terminal of commutator respectively；Second electricity
The two ends held are connected with the outfan of three terminal regulator and the negative output terminal of commutator respectively；The two ends of the 3rd electric capacity respectively with
The negative output terminal triggering end and commutator of TWH8778 high speed electronic switch connects.
During work, an outfan of the first transformator is connected with the main circuit of A.C. welder, and another exports termination
Ground.Microswitch is installed at the welding clamp handle of A.C. welder.Specific works process is as follows: first, and close air-break,
Alternating current power supply becomes DC source successively after the second transformator, commutator carry out blood pressure lowering, rectification.Then, DC source is through three
End manostat sends into TWH8778 high speed electronic switch after carrying out voltage stabilizing.Carry out when workman holds the welding clamp handle of A.C. welder
During weld job, microswitch is touched by hands and closes.Now, DC source triggers TWH8778 height after resistance carries out blood pressure lowering
Speed electrical switch, TWH8778 high speed electronic switch thus turns on, the coil of catalyst thus electric, the normally opened master of catalyst is tactile
Head thus closes, and alternating current power supply thus sends into the first transformator, and sends into A.C. welder after the first transformator carries out blood pressure lowering
Main circuit, A.C. welder is thus energized and starts working.Stop when workman unclamps the welding clamp handle of A.C. welder temporarily
During weld job, microswitch disconnects automatically.Now, TWH8778 high speed electronic switch ends, and the coil of catalyst thus loses
Electricity, the normally opened main contact of catalyst thereby turns off, and A.C. welder thus power-off also quits work.In above process, first
The effect of electric capacity and the second electric capacity is to be filtered DC source.The effect of the 3rd electric capacity is to prevent because of microswitch shake
The power supply causing A.C. welder is unstable.Based on said process, a kind of A.C. welder Energy Saving Control described in the utility model
Circuit is based on brand-new circuit theory, and use that output is big, fast response time, there is stabilization function TWH8778 high
Speed electrical switch controls element as core, it is achieved that when workman stops weld job temporarily, A.C. welder automatically powers off also
Quit work, the most thoroughly prevent A.C. welder to be in Light Condition, thus thoroughly prevent because A.C. welder is in
Light Condition and cause huge waste of energy, and then significantly reduce the operating cost of enterprise.
This utility model is rational in infrastructure, it is ingenious to design, and efficiently solves A.C. welder and is in Light Condition and causes huge
The problem of waste of energy, it is adaptable to A.C. welder.
