Abstract
The utility model discloses an insulating plate with the adjustable thickness for a power transformer, and relates to the technical field of transformers. The insulating plate comprises an iron core which is arranged in an iron core cylinder. Insulating layers are arranged between the iron core and the inner wall of the iron core cylinder, and the insulating layers comprise the first insulating layer and the second insulating layer. The first insulating layer and the second insulating layer are sequentially arranged from the iron core to the inner wall of the iron core cylinder, an extrusion plate is arranged on one side of the second insulating layer, a fastening plate is arranged on one side of the extrusion plate, and the fastening plate is connected with the extrusion plate through a screw. Due to the arrangement of the extrusion plate, the iron core can not shake in the iron core cylinder, the insulating plate is suitable for various types, a piece of insulting paper can not be easily disengaged, and the safety performance of the insulating plate is improved.
Description
Technical field
The utility model relates to the transformer technology field, is specifically related to thickness adjustable type insulation board for a kind of power transformer.
Background technology
Power transformer is a kind of static electric equipment, is to become the equipment of the another kind of or voltage (electric current) that several numerical value is different that frequency is identical for the alternating voltage by a certain numerical value (electric current).When a winding passes to alternating current, just produce the magnetic flux of alternation, the magnetic flux of alternation, by the effect of iron core magnetic conduction, just induces AC electromotive force in secondary winding.The height of secondary induced electromotive force is relevant with the number of a secondary winding number of turn, and voltage swing is directly proportional to the number of turn.Main Function is electric energy transmitting, and therefore, rated capacity is its major parameter.Rated capacity is the habitual value of a performance power, and it is the size that characterizes electric energy transmitting, with kVA or MVA, means, when transformer is applied to rated voltage, according to it, determines the rated current that is no more than temperature limit under rated condition.The iron core apparatus of power transformer, in an iron core cylinder, is provided with insulating barrier between iron core and iron core barrel, and traditional insulating barrier formation is single, easily comes off.
The utility model content
Technical problem to be solved in the utility model is to provide thickness adjustable type insulation board for power transformer a kind of easy for installation, simple in structure.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Thickness adjustable type insulation board for a kind of power transformer, comprise the iron core be arranged in the iron core cylinder, be provided with insulating barrier between described iron core and iron core cylinder inwall, described insulating barrier comprises the first insulating barrier and the second insulating barrier set gradually to iron core cylinder inwall by iron core, described the second insulating barrier one side is provided with stripper plate, described stripper plate one side is provided with binding, and described binding is connected with stripper plate by screw.
Described stripper plate at least is provided with one.
Described the first insulating barrier is insulating paper.
Described the second insulating barrier is insulation board.
The beneficial effects of the utility model are: the utility model, by the setting of stripper plate, can be applicable to various models so that iron core can not rock in the iron core cylinder, and the insulating paper difficult drop-off, has improved the device security performance.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
