Abstract

The utility model discloses a novel T-shaped wiring dry-type transformer with two amorphous alloy cores and belongs to the technical field of design and manufacture of transformers. The transformer adopts the amorphous alloy core design and has high output efficiency and constant power, so that operation of a device is increased. By adopting a double-frame independent amorphous alloy core structure, mutual interference between a power grid and the transformer structure is effectively reduced. A coil adopts a vacuum casting process, has high mechanical strength and strong anti-short circuit ability, and is convenient to maintain. By adopting the high-permeability amorphous alloy cores, loss generated by coil circumfluence is effectively compensated. High-and-low-voltage windings of the transformer are both square windings. The transformer can ensure the operation efficiency of the device, save energy, and simplify design and a processing technique; and the transformer is mainly used in a high-voltage electric power system.

Description

A kind of novel pair of amorphous alloy core T type wiring dry-type transformer
Technical field
The utility model discloses a kind of novel pair of amorphous alloy core T type wiring dry-type transformer, belongs to design of transformer manufacturing technology field.
Background technology
Transformer core is made up of silicon steel sheet, and in order to reduce the heating loss in the iron core, unshakable in one's determination is that the silicon steel sheet closed assembly of 0.23-0.5mm forms by thickness.The silicon content of the silicon steel sheet that transformer is used is than higher.The two sides of silicon steel sheet all is coated with insulating varnish, can be that the silicon steel sheet that is stacked insulate each other like this, and the thickness of insulating varnish has only several microns.Silicon steel sheet is one of key material of making by transformer, and its performance is directly connected to performance and the physical dimension of transformer.The silicon steel sheet that uses unshakable in one's determination has hot rolled silicon steel sheet DR315-50, DR290-50 and cold-reduced silicon sheet etc., the former poor performance, and specific loss is big; Latter's performance is good, and specific loss is little, and by low loss transformer is adopted, low loss transformer is selected the grain orientation cold-reduced silicon sheet of high-quality for use.At present, hot rolled silicon steel sheet is made in the transformer newly and is not used, but still has use in the old transformer.Middle-size and small-size power transformer generally adopts the cold-rolled orientation silicon steel sheet, model 30Q130-35Q165, or cold rolling high magnetic conduction orientation silicon steel sheet, model 27QG100-35QG135; And the silicon steel sheet that distribution transformer adopts also adopts the cold rolling non-orientation silicon steel sheet except above-mentioned two kinds, and model has 35W230-50W350.
T type wiring transformer is a kind of transformer of special purpose, has two kinds of functions of transformer and phase changer.It can become three phase network in the two-phase electrical network, in the place of large capacity single phase load, can improve the degree of unbalance of three phase network.In recent years, the transformer of this wiring is adopted as electroslag furnace, the power transformer of large capacity single phase loads such as core main frequency furnace, resistance furnace is arranged for domestic many productions and R﹠D institution.
Traditional T type wiring transformer ordinary silicon steel disc that adopts unshakable in one's determination, operational efficiency is low, and energy consumption is big, and most of singlecore that adopts, and the design technology difficulty is bigger.
Summary of the invention
At above-mentioned defective and deficiency, the utility model is introduced a kind of novel pair of amorphous alloy core T type wiring dry-type transformer.This structure has broken through the shortcoming that general T type wiring transformer efficient is low, energy consumption is big, design technology is complicated.Can improve equipment operating efficiency, energy savings, simplified design and processing.
Content of the present utility model mainly comprises:
(1). the amorphous alloy core design;
(2). two frame independence amorphous alloy core structures;
(3). coil adopts vacuum pouring technology;
(4). adopt high magnetic conduction amorphous alloy core.
The beneficial effects of the utility model are: described transformer adopting amorphous alloy core design, transformer delivery efficiency are than higher, and power invariability, equipment move and improve; Adopt two frame independence amorphous alloy core structures, effectively reduce electrical network interfering with each other transformer device structure itself; Coil adopts vacuum pouring technology, the mechanical strength height, and anti-short circuit capability is strong, and is easy to maintenance; Adopt high magnetic conduction amorphous alloy core, effectively compensation is because the loss that the coil loop miscarriage is given birth to.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the transformer device structure schematic diagram.
Fig. 2 is the key wiring diagram of T type wiring transformer.
Among Fig. 1, (1) T position transformer coil; (2) return yoke iron core; (3) conjugation iron core; (4) status of a sovereign transformer coil.
Among Fig. 2, A, B, C are former edge joint line terminals, U CBBe the voltage between the BC phase, U CABe the voltage between the AC phase, U ABBe the voltage between the AB phase, U AxBe the voltage between the secondary a phase, U ByBe the voltage between the b phase, N 1Be the former limit number of turn, N 2Be the secondary number of turn.
Embodiment
The two frame independence core constructions of transformer adopting described in the utility model, as shown in Figure 1, be divided into two transformers up and down: (1) is T position transformer, and (4) are status of a sovereign transformer.Two transformers have conjugate moiety.
The amorphous alloy material that adopts unshakable in one's determination.Amorphous alloy material is a kind of new energy-saving material, and it mainly is to be alloy with metals such as iron, nickel, cobalt, chromium and manganese, and adds nonmetalloids such as a spot of boron, carbon, silicon, phosphorus and make, and it has good ferromagnetism.The processing technology complexity of amorphous alloy material, material is hard and crisp, be difficult to shear, so iron core all adopts rectangle structure, and the high-low pressure winding of transformer also adopts rectangle structure accordingly, as shown in Figure 1.Transformer coil adopts the winding with the vacuum pouring explained hereafter, and the product that this mode is produced is difficult for entrapped air, the quality height, and unshakable in one's determination and winding cools off by the cross-ventilation mode.
Fig. 2 is the key wiring diagram of T type wiring transformer.The single-phase transformer that two Daeporis are logical, the used lead of their primary winding is the same, and one the number of turn is N 1, and possess centre tap is arranged, another number of turn is The used lead of their secondary coil too, and the number of turn is N 2These two transformers are coupled together by Fig. 2, and primary winding is received on the three phase mains, and two secondary coils will produce the biphase equilibrium voltage of 90 ° of phase differences.For the sake of clarity, we cry status of a sovereign transformer last (the primary winding number of turn are N 1), another is T position transformer, and (the primary winding number of turn is ).
