Description
Technical field
The utility model relates to transformer, is the transformer secondary iron core of electricity economizer for three phase balance system specifically.
Background technology
Three-phase equilibrium power-saving technique is the special winding utilizing " balance controls transformation system ", interconnection each other, by compensating mutually iron core magnetic flux, keep the consistent of magnetic potential between each phase to greatest extent, thus maintenance three-phase equilibrium, reduction neutral line current is central principle, other power-saving technique integrated balanced type system saving electricity technology.
The transformer of electricity economizer for three phase balance system is the power equipment of the voltage and current of another system by the alternating voltage of a system and current conversion by electromagnetic induction, it is made up of iron core and cover two or more windings thereon, winding is generally wrapped on skeleton, is then enclosed within iron core by skeleton.But existing fabrication of iron core cost is higher, characteristic of magnetization is good not.
Utility model content
For above-mentioned technical problem, the utility model provides that a kind of cost is lower, the transformer secondary iron core of the good electricity economizer for three phase balance system of characteristic of magnetization.
The technical scheme in the invention for solving the above technical problem is: the transformer secondary iron core of electricity economizer for three phase balance system, comprising three can the column iron core of coiling and the crossbeam iron core being connected these three column iron core two ends respectively, described in each, crossbeam iron core is provided with epoxy plate according to this side view on coil one side, is coated with cornerite bar in the corner of epoxy plate and crossbeam iron core.
As preferably, the centre of the length direction of epoxy plate is provided with insulation strip.
As preferably, column iron core described in each comprises the core body of the stacked formation of several piece bar shaped silicon steel sheet, is coated with an insulating paper in core body both sides respectively according to silicon steel sheet shape, has an iron plate in each insulating paper arranged outside.
As preferably, described in each, a through hole has been opened in silicon steel sheet one end, and every three blocks of silicon steel sheets build up one group, and the through hole alignment of silicon steel sheet one end of same group, one end and the other end intersecting of array silicon steel sheet form described core body.
As preferably, the hole of described through hole alignment is opened at iron plate two ends described in each respectively.
As can be known from the above technical solutions, the utility model, by arranging epoxy plate, cornerite bar and insulation strip, substantially increases insulation effect, thus effectively improves the characteristic of magnetization of secondary iron core; Column iron core of the present utility model is stacked by several pieces silicon steel sheets, and a through hole has been opened in each silicon steel sheet one end, not only can reduce noise during work, and cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optimal way of the utility model;
Fig. 2 is column iron core cross-sectional schematic of the present utility model.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, the utility model is described in further detail:
The transformer secondary iron core of electricity economizer for three phase balance system, it comprises three can the column iron core 1 of coiling and the crossbeam iron core 2 being connected these three column iron core one two ends respectively, described in each, crossbeam iron core is provided with epoxy plate 3 according to this side view on coil one side, is coated with cornerite bar 4 in the corner of epoxy plate and crossbeam iron core; Epoxy plate and cornerite bar can play good insulation effect, effectively improve the characteristic of magnetization of characteristic; In order to improve insulation effect further, the centre of the length direction of epoxy plate is provided with insulation strip 5.
As preferably, column iron core 1 described in each comprises the core body 11 of the stacked formation of several piece bar shaped silicon steel sheet, is coated with an insulating paper 12 in core body both sides respectively according to silicon steel sheet shape, has an iron plate 13 in each insulating paper arranged outside; The utility model silicon steel sheet is laminated into core body, and its characteristic of magnetization is better, can ensure that iron core is stable, insulation simultaneously, improve the security performance of transformer by insulating paper and iron plate.
In the utility model, a through hole 14 has been opened in silicon steel sheet one end described in each, every three blocks of silicon steel sheets build up one group, the through hole alignment of silicon steel sheet one end of same group, and one end and the other end intersecting of array silicon steel sheet form described core body, and open porose 6 at the correspondence position of iron plate, when mounted, the through hole of this Kong Yingyu silicon steel sheet is corresponding, so not only can reduce noise during work, and structure is simple, cost is lower, ensures the characteristic of magnetization of core body.
When making transformer, first one end of three column iron cores one crossbeam iron core being connected, then coiling on column iron core, then connecting another crossbeam iron core at three column iron core other ends, be so just made into secondary iron core.
Above-mentioned execution mode is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill of relevant technical field, when not departing from the utility model spirit and scope, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present utility model.
