Description
Technical field
The present invention relates to a kind of method of supplying power to, specifically, be a kind of night electromotor disable after battery to thermal insulation barrel for welding rods method of supplying power to.
Background technology
Overseas project great majority can be used without civil power at Construction Phase, powering only with diesel-driven generator, and on-site generated power machine unlikely keeps 24 hours continuously running, one to be that electromotor continuously runs electromotor for 24 hours unfavorable, two is that electromotor operating cost at night is high, also needs to send someone on duty. The solution of most companies is to be further provided with small generator to solve welding rod constant temperature problem at night at present, ensure 1 to 2 hours the next mornings of welding rod expense, this scheme needs infusion of financial resources to buy electromotor, is also faced with operating cost height at night, problem on duty of need to sending someone.
Chinese patent CN201815818U discloses a kind of heat accumulative welding rod heat preservation bucket on May 4th, 2011, wherein interior intracavity is provided with inner bag, inner bag and staving are provided with heat-insulation layer, inner bag has been embedded in a heat storage, heat storage is internally provided with heat-storing material, heat storage arranged outside has electric heater, and electric heater electrically connects electrical socket and temperature controller. Although after this heat accumulative welding rod heat preservation bucket puts into 5Kg welding rod, the normal welding of welder 4 hours, the temperature of heat-preserving container may remain in more than 70 DEG C, but it is also dependent on electricity consumption, and problem still exists.
Also having people's imagination battery to power to thermal insulation barrel for welding rods, but welding rod constant temperature case required voltage is alternating current 220V, power is also relatively big, minimum also more than 1KW; Electrode dryer voltage is direct current 60V-90V, and power is also little, and the power of 5kg electrode dryer is 54W-120W, it is also difficult to use storage battery power supply.
Therefore the known small generator of Free Region without civil power also exists the problems such as above-mentioned all inconvenience to the mode of welding rod constant temperature insulation at night.
Summary of the invention
The purpose of the present invention, be in that to propose a kind of night economical and practical, easy-operating electromotor disable after battery to thermal insulation barrel for welding rods method of supplying power to.
For achieving the above object, the technical solution of the present invention is:
A kind of battery is to thermal insulation barrel for welding rods method of supplying power to, it is characterised in that comprise the following steps:
A, calculate select set of cells voltage
The various batteries according to 12V, 6V battery 20 hour rate final voltage under different discharge-rates and the relation of discharge time, the voltage selecting set of cells need to more than 60V;
B, calculate battery theoretical value discharge time
6 12V, 120Ah serial battery are adopted to power, supply voltage 72V, the discharge current calculating battery by electrode dryer peak power is 120W �� 72=1.67A, then theoretical value discharge time is 120Ah �� 1.67A=72 hour;
C, determine the depth of discharge of battery system
Being affected by battery pole plates chemical reaction during due to electric discharge, the actual discharge time is less than value of calculation; Time actually used, battery can not discharge by electricity all " zero ", and the capacity that battery can use is less than nominal value, and with the minimizing of battery electric quantity, output voltage also can decline, and depth of discharge is 16.7%��50%.
The battery of the present invention can also be further achieved by the following technical measures to thermal insulation barrel for welding rods method of supplying power to.
Aforesaid method, wherein said battery is maintenance-free battery.
Aforesaid method, wherein said maintenance-free battery is series-fed.
Aforesaid method, wherein said battery is ferric phosphate lithium cell.
After adopting technique scheme, the battery of the present invention has the advantage that to thermal insulation barrel for welding rods method of supplying power to
1, circuit structure is simple;
2, battery charging on daytime, night powers to electrode dryer;
3, put into little, easily operate, solve to remain welding rod constant temperature at night the same day, it is ensured that the next morning, welder had 1-2 hour with amount of electrode until electromotor second day starts on the roasting welding rod of after bake continues, need to reduce engineering cost.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
Referring now to final voltage under different discharge-rates of the battery product of 12V, 6V battery 20 hour rate that Fig. 1, Fig. 1 are the embodiment of the present invention and the graph of a relation of discharge time. As it can be seen, these numerical value described are representative to common lead-acid accumulator. Slightly declining in time it is also seen that battery discharge starts rear voltage, the voltage therefore selecting set of cells need to more than 60V, and the present embodiment adopts 6 12V, 120Ah maintenance-free battery series-feds, supply voltage 72V.
The discharge current calculating battery by thermal insulation barrel for welding rods peak power is 120W �� 72=1.67A. Discharge time is 120Ah �� 1.67A=72 hour. This is only calculated value, because being primarily due to when discharging is affected by battery pole plates chemical reaction, and the actual discharge time is less than value of calculation; Secondly, when storage battery is actually used, battery can not discharge by electricity all " zero ", that is the capacity that battery can use is less than nominal value, minimizing with battery electric quantity, output voltage also can decline, so the actual discharge time is less than 72 hours, the present embodiment only needs battery to power 12 hours in night, therefore meets heat-preservation cylinder and powers needs. It addition, adopt 6 12V, 120Ah maintenance-free battery series-feds to be additionally contemplates that the relation of the life of storage battery and depth of discharge. Within the specific limits, depth of discharge is more big, and the life of storage battery is more short. And the electricity of accumulator (ampere-hour) is more big, power supply capacity is more strong, and the probability of accumulator over-discharge is more little. Therefore when carrying out design of circuit system, through considering, it is suitable that depth of discharge is decided to be 16.7%��50%.
Maintenance-free battery charging on daytime, night powers to electrode dryer. For ensureing that the next morning, welder had 1 to 2 hours welding rod expenses, calculate 20KG welding rod according to scene and can meet demand, therefore set 4 Battery pack groups and power to 4 heat-preservation cylinders respectively. The previous day is electrode dryer unified management After Hours, and electrode dryer is not detained teams and groups. Electrode dryer and residue welding rod must return in time wlding storehouse, and by the unified keeping in wlding storehouse, calorstat residue welding rod in scene and storehouse is respectively charged in 4 heat-preservation cylinders by wlding storehouse, and set of cells is switched to heat-preservation cylinder powers.
Embodiment 2
The present embodiment is except using ferric phosphate lithium cell, and all the other are with embodiment 1.
The present invention has substantive distinguishing features and significant technological progress, the battery of the present invention to thermal insulation barrel for welding rods method of supplying power to by less put into and be easily operated in the way of solve the problem remaining welding rod constant temperature at night the same day, also ensure that the next morning, welder had 1 to 2 hours welding rod expenses until electromotor second day starts on the roasting welding rod of after bake continues, simple in construction is easy to spread.
Above example is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, it is also possible to make various conversion or change. Therefore, all equivalent technical schemes also should belong to scope of the invention, should be limited by each claim.
