Abstract

The utility model relates to a transformer, in particular to a dry-type transformer for single-phase 10kV and 20kV mutual conversion. The transformer comprises an iron core, wherein a winding is wound on the iron core. The transformer is characterized in that the winding is divided into a low-voltage winding and a high-voltage winding, wherein switching between serial connection and parallel connection of the low-voltage winding and the high-voltage winding is realized through a connecting plate; the iron core is of a rectangular structure and is formed by coiling an amorphous alloy belt; the low-voltage winding is formed by winding a foil; and the high-voltage winding is made from a vacuum casting resin. Therefore, the transformer has the beneficial effects of high overload ability, high short circuit resistance, low no-load loss and resource saving.

Description

A kind of single-phase 10kV and 20kV change dry-type transformer each other
(1) technical field
The utility model relates to a kind of transformer, and particularly a kind of single-phase 10kV and 20kV change dry-type transformer each other.

Present stage, China's residential electricity consumption circuit major part is the 10kV circuit, and in order to reduce line loss and to improve transmission power, the 20kV circuit is optimized selection.Our existing transformer is 10kV, and the 10kV transformer original if circuit is upgraded to 20kV will be changed, and cause the significant wastage of resource.
(3) summary of the invention
The utility model provides a kind of single-phase 10kV and 20kV to change dry-type transformer each other in order to remedy the shortcoming of prior art.
The utility model is realized through following technical scheme:
A kind of single-phase 10kV and 20kV change dry-type transformer each other, comprise iron core, are wound with winding on the iron core, it is characterized in that: said winding is divided into low pressure winding and high pressure winding, and high pressure winding and low pressure winding are realized series connection and parallelly connected switching through connecting plate; Said iron core is a rectangular configuration, and adopts amorphous alloy strips to roll to form; Said low pressure winding be paper tinsel around the mode coiling, the high pressure winding is the vacuum pouring resin.
Therefore, the beneficial effect of the utility model is: this single-phase 10kV and 20kV change dry-type transformer each other, and overload capacity is strong, and anti-short circuit capability is strong, and no-load loss is low, economizes on resources.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the general arrangement schematic of the utility model.
Accompanying drawing 2 is the 10kV connection principle sketch map of the utility model.
Accompanying drawing 3 is the 20kV connection principle sketch map of the utility model.
Among the figure, 1 iron core, 2 windings, 3 number of turn A, 4 number of turn B, 5 number of turn C, 6 number of turn D.
(5) embodiment
Use this utility model, this embodiment comprises iron core 1, is wound with winding 2 on the iron core 1, and it is characterized in that: said winding 2 is divided into low pressure winding and high pressure winding, and high pressure winding and low pressure winding are realized series connection and parallelly connected switching through connecting plate; Said unshakable in one's determination 1 is rectangular configuration, and adopts amorphous alloy strips to roll to form; Said low pressure winding be paper tinsel around the mode coiling, the high pressure winding is the vacuum pouring resin.
Adopt the single-phase 10kV and the 20kV of the utility model to change dry-type transformer each other, number of turn A3 is parallelly connected with number of turn B4, and number of turn C5 is parallelly connected with number of turn D6; Wire glass increases by 1 times, and the number of turn is 1/2 (number of turn A3+B4+C5+D6), is used for the 10kV circuit; Connection principle shown in accompanying drawing 2, when number of turn A3 with after number of turn B4, number of turn C5, number of turn D6 connect, when the number of turn is parallel connection 2 times; Wire glass is 0.5 times of parallel connection, is applied to the 20kV circuit, and elementary diagram is as shown in Figure 3.Therefore, the beneficial effect of the utility model is: this single-phase 10kV and 20kV change dry-type transformer each other, and overload capacity is strong, and anti-short circuit capability is strong, and no-load loss is low, economizes on resources.
