Abstract
The utility model relates to a power supply cabinet for high-power flash butt welding machines, comprising a cabinet body, wherein the cabinet body is provided with a three-phase high-power voltage regulator to be connected with a high-voltage transformer; the voltage regulator is connected with a transformer the output end of which leads to an electric welding machine. By integrating a three-phase high-power voltage regulator and a transformer into the cabinet body 10, the utility model takes advantage of the principle of voltage regulation and three-to-single phase inversion technologies to transform the extremely unbalanced load into extremely balanced load, which can reduce line losses and effectively balance the grid load; therefore, the utility model guarantees the voltage needed for welding and can further improve the welding quality.
Description
Technical field
The utility model relates to a kind of power cabinet, is meant a kind of power cabinet of high-power flash butt welder especially.
Background technology
At present, high-power flash butt welder is generally the two-phase power supply, and it is a kind of utmost point unbalanced load for electric power system.As shown in Figure 1, the high-power flash welder 1 of tradition is when butt welding, directly be connected with high-tension transformer 2, it is when butt welding, can cause line drop big greatly because of electric current, so that slag inclusion can appear in weld bond and bubble produces, thereby make the welding failure, therefore, it is real in necessary that industry need be provided by a kind of power cabinet of high-power flash butt welder that provides.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide a kind of power cabinet of high-power flash butt welder, and it can balanced network load, and institute must voltage when having ensured welding, thereby improve welding quality.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of power cabinet of high-power flash butt welder comprises a cabinet, and this cabinet is equipped with a three-phase high-power voltage stabilizer for the high-tension transformer connection, and this voltage-stablizer is electrically connected the transformer that an output is exported to electric welding machine.
The advantage of the utility model is to take voltage stabilizing and the single-phase technology of three phase transformations, and utmost point unbalanced load is become utmost point balanced load, has lowered line loss, balanced effectively network load, and institute's palpus voltage further improves welding quality when having ensured welding.
Description of drawings
Fig. 1 is the prior art schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
As shown in Figure 2, a kind of power cabinet of high-power flash butt welder, comprise a cabinet 10, this cabinet 10 is equipped with a three-phase high-power voltage stabilizer 20, the supplying power for input end net mesohigh transformer 40 of this voltage-stablizer 20 connects, and this voltage-stablizer 20 is electrically connected a transformer 30, so that the burning voltage of this transformer 30 to be provided; The output of this transformer 30 is electrically connected to supply with electric welding machine 50.Its operation principle is: connect high-tension transformer 40, flow to transformer 30 after voltage-stablizer 20 of the present utility model is handled, this transformer 30 is transformed into the single-phase operating voltage of exporting to butt welding machine 50 with three-phase.
The utility model design focal point is to utilize three-phase high-power voltage stabilizer 20 and transformer 30 to gather in cabinet 10, wherein by taking voltage stabilizing and the single-phase know-why of three phase transformations, utmost point unbalanced load is become utmost point balanced load, lowered line loss, balanced effectively network load, institute's palpus voltage when having ensured welding has been created advantage for improving welding quality.
The above, it only is the preferred embodiment of the power cabinet of the high-power flash butt welder of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
