Fig. 1 is the structural representation of this utility model embodiment common box type isolating transformer。
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
The problem that this utility model embodiment increases erecting bed floor space for isolating transformer of the prior art, it is proposed to a kind of common box type isolating transformer, reduces the overall volume of transformator, saves the floor space of transformator erecting bed。
Fig. 1 is the structural representation of this utility model embodiment common box type isolating transformer。Refer to Fig. 1, the common box type isolating transformer that this utility model embodiment provides, including: a kind of common box type isolating transformer, including: transformer-cabinet 10, at least two single-phase transformer device body 20 and auxiliary transformer device body 30, described at least two single-phase transformer device body 20 and described auxiliary transformer device body 30 are installed in described transformer-cabinet 10, each single-phase transformer device body 20 includes a primary side winding and a pair vice-side winding, the primary side winding of described at least two single-phase transformer device body 20 is drawn after parallel connection in described transformer tank body, the vice-side winding of described at least two single-phase transformer device body 20 and described auxiliary transformer winding are individually drawn respectively in described transformer-cabinet 10。
The common box type isolating transformer that this utility model embodiment provides, by described at least two single-phase transformer device body 20 and described auxiliary transformer device body 30 are installed in described transformer-cabinet 10, the primary side winding of described at least two single-phase transformer device body 20 is drawn after parallel connection in described transformer tank body, the vice-side winding of described at least two single-phase transformer device body 20 and described auxiliary transformer winding are individually drawn respectively in described transformer-cabinet 10, it is achieved that the multiple winding of transformer secondary and an independent power supply mode assisting winding。During use, described independent auxiliary transformer is used as starting。The common box type isolating transformer that this utility model embodiment provides, by being installed in same transformer tank body by multiple transformer bodies, reduces the overall volume of transformator, saves the floor space of transformator erecting bed；Decrease the material cost of transformator simultaneously；Again, draw after being achieved that parallel connection due to the primary side winding of multiple transformators in transformer tank body, it is not necessary to be connected in parallel transformer tank is external, thus the cabling further reduced outside casing connects the space taken。
