Abstract

The invention discloses a dry type transformer for deepwater and relates to the technical field of transformers. According to the technical scheme, the dry type transformer for the deepwater comprises an iron core body and coil windings and is characterized in that the iron core body is composed of yokes, roll iron cores and screws. The three roll iron cores are vertically arranged on the same horizontal plane, and the connection lines of the center of the end faces of the three roll iron cores form a triangle. The yokes are in a Y shape, and three protruded portions of the yokes form 120-degree included angles in a pairing mode. The two yokes are clamped at the upper ends and the lower ends of the three roll iron cores, and the three screws are used for integrally fixing the three roll iron cores and the two yokes at the two ends respectively. The three roll iron cores are sleeved with the three coil windings respectively, and outgoing lines of all the coil windings are connected with external cables respectively. An insulating layer is arranged on the surface of a transformer body formed by installing the coil windings on the iron core body. The dry type transformer for the deepwater can be placed in a deepwater area to work, electric power is conveyed to the coil windings of the transformer from the water surface through the cables so as to provide applicable electric power for work in the deepwater, and the dry type transformer for the deepwater has the advantages of being small in size, high in conversion efficiency, strong in insulating property, safe and reliable in work and the like.

Description

The deep water dry-type transformer

Technical field

The invention belongs to the transformer technology field, be specifically related to the deep water dry-type transformer.

Background technology

Along with the develop rapidly of national economy, electric power has become the indispensable power source of industry-by-industry, and power transformer also generally is used widely in our daily life.But often need to apply in some special industries the requirement that special transformer meets its applied environment, as long apart from the electric power transport loss for reducing at work as the deep water power device, just need to adopt high-pressure delivery electric power to destination, then transformation is supplied the deep water power device on the spot.And existing transformer technology mostly only adapts to the less demanding occasion of insulation environment, although some so-called full-sealed transformers are arranged, the relative conventional environment of its sealing property is higher with transformer, can not meet the requirement of safe changing voltage in deepwater environment.

Summary of the invention

The objective of the invention is to overcome existing transformer technology and can not adapt to the deficiency the high external pressure environmental work of deep water, provide a kind of insulation property well and have the deep water dry-type transformer than high leakproofness.

For achieving the above object, technical scheme of the present invention comprises iron-core workpiece and coil windings.It is characterized in that: iron-core workpiece is comprised of yoke, volume iron core and screw, and 3 volume iron cores are vertically set on a horizontal plane, and the line of centres of 3 volume iron core end faces is equilateral triangle; The Y-shaped shape of yoke, its 3 lug bosses are in 120 degree angles; 2 yokes are clamped in the two ends up and down of 3 volume iron cores, and respectively 2 yokes at 3 volume iron cores and two ends are fixed as one with 3 screws; 3 groups of coil windings are set on 3 volume iron cores, and the lead-out wire of each coil windings is connected with external cable respectively.The transformer body surface formed after coil windings is installed at iron-core workpiece, and integral sealing is provided with certain thickness insulating barrier.

Described yoke is permeability magnetic material, all is provided with circular hole on 3 lug bosses;

Described volume iron core is to roll with the non-crystaline amorphous metal coiled material, and center is provided with through hole;

Described insulating barrier in the setting of transformer body face seal is integrated poured moulding.

The invention has the beneficial effects as follows: transformer volume iron core system rolls with the non-crystaline amorphous metal coiled material, has good ferromagnetism, has improved the transformer conversion efficiency; Between the three-phase coil winding, be equilateral triangle and distribute, effectively utilize space, in the situation that equal transformer capacity has been dwindled overall volume; At transformer fe core body and the casting insulated layer of coil winding arrangement external overall, coil windings lead-out wire and external cable connecting portion also are sealed in insulating barrier, have improved the reliability of the whole and outside insulation exponential sum work of transformer.

Embodiment

As shown in Figure 6 and Figure 8, the volume iron core 5 of 3 columns is to roll with the non-crystaline amorphous metal coiled material, is provided with through hole 8 at the center of volume iron core 5;

As Fig. 5 and shown in Figure 7,2 yokes 6 are Y-shaped shape all, is to use the magnetic conduction board making, and the center line of 3 lug bosses of yoke 6 is in 120 degree angles, is provided with circular hole on each lug boss;

As shown in Figure 4,3 volume iron cores 5 are clamped between 2 yokes 6, and screw 7 orders are passed circular hole, the through hole 8 on volume iron core 5 and the circular hole on upper yoke 6 on lower yoke 6, and fastening with nut, namely form iron-core workpiece 1.

As shown in Figure 2,3 coil windings 2 are set on 3 volume iron cores 5 of iron-core workpiece 1, and the lead-out wire of coil windings 2 all is connected with cable 4; In the transformer body outside assembled, integral sealing is cast with insulating material, forms insulating barrier 3.

As shown in figures 1 and 3, transformer body, coil windings lead-out wire and cable connecting part all are coated in insulating material, with the external environment condition sealed insulation.

The present invention is to be seated in the deep water service area in the course of work, by cable from the transmit electric power coil windings of deep water dry-type transformer of the water surface, for operation under deep water provides suitable power.
