Abstract
The utility model relates to a three-phase and multi-gear voltage regulator, belongs to the technical field of power line voltage regulation, and adopts the technical scheme that a three-phase auto-transformer and short circuit switches (4) are included; a main winding (1) of the three-phase auto-transformer is connected in series with a secondary winding (2); a plurality of pigtails (3) are led out of each phase of the secondary winding; three pigtails led out of the three-phase secondary winding form a set of pigtails connected with one short circuit switch; and a plurality of sets of pigtails led out of the three-phase secondary winding are connected with a plurality of short circuit switches. The three-phase and multi-gear voltage regulator can realize multi-gear voltage regulation, can turn down or up the power line voltage according to the voltage fluctuation range and production requirements so as to meet the production requirements of a factory, has the advantages of reasonable structure, convenience in use, automatic multi-gear voltage regulation and the like, and can automatically turn up the voltage when the factory voltage is low. Therefore, normal production can be ensured.
Description
Technical field:
The utility model relates to a kind of three-phase and keeps off voltage regulator more, belongs to supply power voltage regulation technology field.
Background technology:
At present, common voltage regulator can not divide the class pressure regulation as required, when supply power voltage is higher than rated value or is lower than rated value, can only carry out the primary voltage adjustment, very inconvenient, when mains ripple is big, can not satisfy the plant produced needs, particularly when factory's voltage is low,, will influence production if can not heighten voltage.
The utility model content:
The utility model purpose provides a kind of three-phase and keeps off voltage regulator more, can carry out many retainings to supply power voltage and reconcile, and comes regulation voltage according to the fluctuation of voltage, satisfies and produces needs, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
A kind of three-phase keeps off voltage regulator more, comprise three-phase single-circuit transformer, shorting switch, three single-circuit transformers get main winding cross-under auxiliary winding, on the auxiliary winding of each phase, draw several taps, three taps that the three-phase auxiliary winding is drawn are one group of tap, connect a shorting switch, the some groups of taps that the three-phase auxiliary winding is drawn connect several shorting switchs.
Said tap group number is arbitrarily, determines the corresponding retaining range of regulation of each group tap as required.
Said shorting switch is a contacts of contactor.
The beneficial effects of the utility model: adopt the utility model, can realize the pressure regulation of many retainings, turn down or the high jump supply power voltage according to scope range of the fluctuation of voltage and production needs, satisfy the plant produced needs, have rational in infrastructure, easy to use, automatic characteristics such as many retainings pressure regulation, when factory's voltage is low, can heighten voltage automatically, guarantee to produce and normally carry out.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Among the figure: main winding 1, auxiliary winding 2, tap 3, shorting switch 4.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of three-phase keeps off voltage regulator more, comprise three-phase single-circuit transformer, shorting switch 4, three single-circuit transformers get main winding 1 serial connection auxiliary winding 2, on the auxiliary winding of each phase, draw several taps 3, three taps that the three-phase auxiliary winding is drawn are one group of tap, connect a shorting switch, the some groups of taps that the three-phase auxiliary winding is drawn connect several shorting switchs.
Present embodiment uses four shorting switchs for to draw four taps on auxiliary winding, is divided into four retainings and carries out the voltage conciliation; For ease of explanation, the shorting switch sequence number that auxiliary winding is drawn the tap connection from top to bottom is followed successively by four, three, two, one, and when needs boosted, the shorting switch four that the nethermost tap of auxiliary winding connects was opened shorting switch three closures; Further boost if desired, shorting switch two, one closure, voltage can rise to predetermined value.When the needs step-down, shorting switch one is opened, shorting switch two closures; If desired further, closed successively shorting switch three, four, voltage is reduced to desired value.
Claims (2)
1. a three-phase keeps off voltage regulator more, it is characterized in that comprising three-phase single-circuit transformer, shorting switch (4), three single-circuit transformers get main winding (1) serial connection auxiliary winding (2), on the auxiliary winding of each phase, draw several taps (3), three taps that the three-phase auxiliary winding is drawn are one group of tap, connect a shorting switch, the some groups of taps that the three-phase auxiliary winding is drawn connect several shorting switchs.
2. keep off voltage regulator according to the described three-phase of claim 1 more, it is characterized in that said shorting switch is a contacts of contactor.
