Description
Technical field
The present invention relates to a kind of solder technology.Particularly relate to open-air no civil power occasion and accomplish a kind of field emergency Arc Welding Power of welding.
Background technology
Conventional Arc Welding Power is to lean on the civil power input to accomplish welding.This has just determined do not having under the construction occasion of commercial power supply, is to lean on conventional Arc Welding Power to accomplish welding.But, there is not the field construction of commercial power supply at some, for example job site of long-distance transport pipes etc. is again must can weld just to accomplish construction task.At present, normally adopt diesel engine generator generating, supply with conventional Arc Welding Power and accomplish welding.But diesel engine generator generating supply Arc Welding Power has following shortcoming:
1, voltage instability.Cause conventional Arc Welding Power welding quality unstable.
2, power consumption is bigger.This is because the more power factor (PF) that causes of power conversion link is lower.
3, contaminated environment.Because the waste gas that diesel combustion produces and the noise of diesel engine generator etc. have certain influence to open-air biological environment.
4, cost is high, heavy.Diesel engine generator-conventional Arc Welding Power system, cost is higher, and volume and weight is all bigger, and transportation, construction etc. are inconvenience all.
The solution that adopts special-purpose diesel oil electric welding machine is also arranged.This scheme is that the diesel engine generator and the source of welding current are integrated into an equipment, and the source of welding current wherein is an adaptive diesel engine generator and designing.But also only can avoid the shortcoming of aforesaid " voltage instability causes the welding quality instability ", other shortcoming still exists.
For example, the conventional welding power source system of existing described diesel engine generator is shown in Fig. 1 (a); Existing diesel oil electric welding machine is shown in Fig. 1 (b).
Summary of the invention
Technical problem to be solved by this invention is; Provide a kind of at the energy saving and environment friendly Arc Welding Power that does not reduce under the welding quality prerequisite; Progressively to replace diesel engine generator-conventional Arc Welding Power system, reach the field emergency Arc Welding Power of the green welding target of energy-conserving and environment-protective.
The technical scheme that the present invention adopted is: a kind of field emergency Arc Welding Power; Comprise: the batteries that connects successively, IGBT module and output filter unit; It is electric arc that the output of described output filter unit connects load; Also be provided with control unit, the signal output part of described control unit is through the signal input part of driver module connection IGBT module, and the output of described output filter unit also connects the signal input part of control unit through the Hall voltage current sensor.
The output of described batteries also is connected with low pressure alarming and overcurrent alarm unit; Described low pressure alarming is connected the signal input part of described control unit with the signal output part of overcurrent alarm unit; The signal output part of described control unit also connects charging module, and the output of described charging module connects described batteries.
The signal input part of described control unit also is connected with user-friendly parameter setting and state display module.
The pwm signal of described control unit output inputs to the IGBT module through driver module.
A kind of field emergency Arc Welding Power of the present invention has following beneficial effect:
1, energy-conservation.Because the power conversion link is few, so power factor (PF) is higher.
2, environmental protection.Because what adopt is the clean energy resource storage battery, therefore can not produce waste gas and the noise that diesel combustion produces, help the protection of open-air natural environment.
3, welding quality stable.Because the diesel engine generator generating voltage is unstable, and the design basis of the conventional Arc Welding Power stable mains-supplied that is voltage, so welding quality less stable comparatively speaking.But the field emergency Arc Welding Power adopts the stable batteries of voltage as primary power source, and makes Arc Welding Power according to the storage battery power supply characteristics, so welding quality is more stable relatively.
4, cost is low, volume is little.Because the diesel engine generator volume is often bigger, cause that diesel engine generator-conventional Arc Welding Power system bulk is bigger, and cost is higher.But field emergency Arc Welding Power volume is much smaller than existing open-air welding system.
5, safe.Because the diesel engine generator-a large amount of diesel oil supply of conventional Arc Welding Power system's needs, inflammable diesel oil becomes potential safety hazard, and fail safe is lower.And the field emergency Arc Welding Power, owing to adopt storage battery as primary power source, fail safe is higher.
In sum; The field emergency Arc Welding Power compared with prior art; Have plurality of advantages, the diesel engine generator of can substitute fully that power consumption is big, contaminated environment, welding quality are relatively poor-conventional Arc Welding Power system, social benefit that is produced and economic benefit are all quite considerable.
