Specific embodiment

It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality The feature applied in example can be combined with each other.

Many details are explained in the following description in order to fully understand the utility model, still, this is practical Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below The limitation of the specific embodiment of specification.

Embodiment 1, the utility model release the construction of 10kV integration pole type transformer platform for country, it is desirable that using a kind of The problem of bus totally-enclosed, prefabricated without metal shell, devises a kind of prefabricated bus of pole type transformer as shown in Figure 1, including The casting insulated body 1 of bus, is provided with bus as shown in Figure 2 whole 2 in the casting insulated body 1 of bus, and bus whole 2 includes simultaneously Four phase copper bars 3 being arranged in the casting insulated body 1 of bus are arranged, it is naked for can be seen that the both ends of four phase copper bars 3 in conjunction with Fig. 1 and Fig. 2 It is exposed at the outside of the casting insulated body 1 of bus, passes through airspace, top exposed part between the bus-bars conductor of exposed part It is connected perpendicular to the casting insulated body 1 of bus with transformer, bottom end exposed part is parallel to the casting insulated body 1 of bus and extends to JP cabinet The inside of top cover；For the ease of more clearly illustrating bus whole 2, as shown in figure 3, the explosive view of bus whole 2 is provided, The primary structure of bus whole 2 is four phase copper bars 3, is that two symmetrically arranged intermediate copper bars 31 and two are symmetrical arranged respectively Edge copper bar 32, be provided with insulation board 4, it is preferable to use epoxy resins insulation plate between four copper bars；The utility model is maximum The characteristics of be that the shape of bus entirety is realized by bending and welding, do not need to be bolted, can utmostly reduce Space is specifically such as exactly the bottom end of four phase copper bars 3, that is, the exposed part parallel with the casting insulated body 1 of bus, only needs According to physical length situation, vertical bending twice is carried out to the bottom of four phase copper bars 3 respectively, effect as shown in Figure 3 can be realized Fruit, and the part that top is vertical with the casting insulated body 1 of bus, Cong Tuzhong also it is clear that the top of intermediate copper bar 31 into The top of 1 vertical bending of row, edge copper bar 32 carries out 3 vertical bendings, then respectively in the top planes weldering of four copper bars Its direction can be changed in the copper bar for connecting one block of identical material, makes its top perpendicular to the casting insulated body 1 of bus, in this way Design only just increases the distance between phase and phase copper bar by bending and welding, while not needing bolt and being attached, not only Components are saved, space is also ad save.

By glass tape 5 (in figure for ease of description, four phase copper bars 3 and the insulation board 4 for being used to be spaced are bundled Glass tape 5 illustrates only part), form bus whole 2, then by bus whole 2 and nut fastener 6 be placed into together as It is poured in prefabricated bus mold shown in Fig. 4 with epoxy resin, obtains the casting insulated body 1 of bus, it is casting insulated to bus It after body 1 is fixed-type, is taken out from mold, obtains i.e. a kind of prefabricated bus of pole type transformer of the utility model, the utility model It is integrally formed by poured with epoxy resin, no metal shell, good airproof performance is small in size, corrosion-resistant, and does not have to maintenance, mentions significantly The convenience of height installation and the safety used.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this The protection scope of type technical solution.
