Abstract
The utility model discloses an elasticizer 24VDC power supply system, connected between a three-phase power supply and an elasticizer control system, comprising a variable pressure stabilizer (100) provided with an input end and an output end, wherein the input end is electrically connected with a three-phase power supply, and the output end is electrically connected with the elasticizer control system. The variable pressure stabilizer can convert three-phase power supply into 24 VDC power supply needed by the system. The technical effects lie in that the maintenance cost is lower, without need of buying components specially from manufacturer, the maintenance is simple, which further lowers the maintenance cost; the operation is stable and reliable, other abnormal lines do not affect the normal operation of the variable pressure stabilizer unless the power supply system is interrupted.
Description
Technical field
The utility model relates to a kind of elasticizer 24VDC electric power system.
Background technology
Please refer to Fig. 1, existing elasticizer 24VDC electric power system, it is connected between 380V three phase mains L1, L2, L3, main circuit of converter S and the elasticizer control system K.Existing elasticizer 24VDC electric power system, it comprises a rectification stepup transformer G2, a lowering and stabilizing blood pressure device G1 and a K switch 107, described rectification stepup transformer G2 has the first input end and first output, and described lowering and stabilizing blood pressure device G1 has second input and second output.The first output electricity of described rectification stepup transformer G2 meets 380V three phase mains L1, L2, L3, so that 380V three phase mains L1, L2, L3 become 550VDC through rectification stepup transformer G2, and by the output of first output.Described main circuit of converter S also exports 550VDC by K switch 107.The second input electricity of described lowering and stabilizing blood pressure device G1 connects first output and the K switch 107 of rectification stepup transformer G2, be duplicate supply (550VDC), so that 550VDC becomes 24VDC through lowering and stabilizing blood pressure device G1, and by the output of second output, the described second output electricity meets elasticizer control system K, so that described elasticizer control system K can obtain 24VDC (24V direct voltage).
This existing elasticizer 24VDC electric power system has following deficiency: 1, G1 is equivalent to duplicate supply (550VDC) power supply, need the 550VDC-24VDC formula of original-pack crust mug(unit of measure) configuration just can reach the DC power supply that this electric pressure requires, the cost height, Buying Cycle is longer, break down and also can only send producer's maintenance, not only maintenance cost height but also maintenance cycle are long, bring very burden to ordinary maintenance; 2, G2 is that the rectification of 380VAC-550VD is boosted, it also is the exclusive accessory of Ba Mage, be difficult to find the rectification stepup transformer of this kind electric pressure on the market, spare part also must be bought from the Ba Mage aspect, the cost height, the Buying Cycle is longer, breaks down and also can only send producer's maintenance, not only maintenance cost height but also maintenance cycle are long, bring very burden to ordinary maintenance; 3, in actual applications; when board is shut down, have stalling current and impact G1 by main circuit of converter S; reduced the useful life of G1; failure rate increases; the job stability variation; and the 24V DC power supply that G1 provided is the core of whole elasticizer, and the G1 elasticizer that in a single day breaks down just can't afford to drive.
The utility model content
The utility model provides a kind of elasticizer 24VDC electric power system, and it has overcome the existing deficiency of elasticizer 24VDC electric power system in the background technology.
The technical scheme that is adopted that the utility model solves its technical problem is:
A kind of elasticizer 24VDC electric power system, it is connected between three phase mains and the elasticizer control system, it comprises a transformation pressurizer (100), described transformation pressurizer (100) has input and output, described transformation pressurizer (100) input electricity connects three phase mains, and described transformation pressurizer (100) output electricity connects the elasticizer control system.
Among one preferred embodiment, described transformation pressurizer (100) is the transformation pressurizer of 380VAC-24VDC.
The technical program is compared with background technology, and it has following advantage:
Transformation pressurizer (100) by a suitable capacity replaces, directly become the required 24VDC power supply of system from three phase mains circuit L1, L2, L3, then can overcome the existing deficiency of background technology, and produce following technique effect: a, maintenance cost is lower, do not need to buy from producer specially, easy to maintenance, maintenance cost is lower; Unless the outage of b power-supply system, other circuit can not have influence on the normal operation of G unusually, and it is more reliable and more stable to work.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the schematic diagram of the elasticizer 24VDC electric power system of background technology.
Fig. 2 has illustrated the schematic diagram of the elasticizer 24VDC electric power system of a preferred embodiment.
Embodiment
Please refer to Fig. 2, a kind of elasticizer 24VDC electric power system, it is connected between 380V three phase mains L1, L2, L3 and the elasticizer control system K.Described elasticizer 24VDC electric power system, it comprises a transformation pressurizer 100, described transformation pressurizer (G) 100 has input and output, described transformation pressurizer 100 input electricity meet 380V three phase mains L1, L2, L3, described transformation pressurizer 100 output electricity meet elasticizer control system K, the voltage stabilizing of 380V three phase mains transformation being become the 24V direct voltage, and elasticizer control system K is powered by described transformation pressurizer 100.
Among the present embodiment, described transformation pressurizer 100 can directly be selected the transformation pressurizer of 380VAC-24VDC for use.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
