Dry type transformer for deepwater

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

technical field [0001] The invention belongs to the technical field of transformers, in particular to dry-type transformers for deep water. Background technique [0002] With the rapid development of the national economy, electricity has become an indispensable source of power for various industries, and power transformers are widely used in our daily life. However, in some special industries, it is often necessary to use special transformers to meet the requirements of their application environments. For example, in order to reduce the loss of long-distance power transmission in deep water power devices, it is necessary to use high voltage to transmit power to the destination, and then transform the voltage supply locally. Deep water power device. Most of the existing transformer technologies are only suitable for occasions where the insulation environment is not high. Although there are some so-called fully sealed transformers, whose sealing performance is higher than tha...
