Abstract
The utility model discloses a tertiary winding continuous voltage adjusting rectifier transformer, which is formed by a main transformer body and a string transformer body. The main transformer body is combined with the string transformer body via a valve-side low voltage winding by means of an 8-shaped coil structure, the valve-side low voltage winding is composed of a valve-side low voltage star-joint winding and a valve-side low voltage angle-joint winding, a line-side high voltage winding is a primary winding, and the valve-side low voltage winding is a secondary winding. The rectifier transformer is characterized in that a tertiary winding is formed by a fine-tuning winding, a coarse-tuning winding and a string-transforming primary winding, the fine-tuning winding is connected in series with the coarse-tuning winding via a fine-tuning winding contact, and the fine-tuning winding and the coarse-tuning winding supply power to the string-transforming primary winding. The rectifier transformer has the advantage of being capable of realizing continuous voltage adjustment demand in large scale by adopting a tertiary winding voltage adjusting manner without power disconnection, and realizing single unit 12 phase output without a no-load inverted step switch.
Description
Technical field
The utility model relates to rectifier transformer, especially relates to a kind of tertiary winding continuous voltage adjustment rectifier transformer.
Background technology
Large rectifier transformer has a kind of tertiary winding pressure adjusting structure usually at present.Because the electrolysis tank capacity of aluminum electrolysis industry has reached more than 250,000 tons at present, therefore require rectifier transformer separate unit capacity generally all more than 100,000 kVA, and electric pressure is generally two kinds of 220kV, 330kV, the valve side requires separate unit 12 to export mutually.Tertiary winding voltage regulating rectifier transformer (separate unit 12 phases) has the advantages that the separate unit structural capacity is little, in light weight, loss is little with respect to the step-down self coupling rectifier transformer or the formula rectifier transformer that falls progressively.The structural capacity of tertiary winding voltage regulating rectifier transformer is 75% of the formula rectifier transformer structural capacity that falls progressively.If the pressure regulation claimed range is big, as: transfer to 100% since 0, commonly used must be with no-load to fall section could to realize the range of regulation requirement, but be with no-load rectifier transformer section under power-off condition, could realize pressure regulation, can't satisfy under the situation of not cutting off the power supply and realize continuous voltage regulating.
Summary of the invention
The purpose of this utility model is to provide a kind of tertiary winding continuous voltage adjustment rectifier transformer, and it can be under the situation of not cutting off the power supply realizes the continuous voltage regulating requirement on a large scale, realizes that separate unit 12 export mutually, and need not no-load falls a section switch.
The purpose of this utility model is achieved in that the utility model becomes the device body by main transformer device body and string and forms, main transformer device body and string become the device body and adopt 8 word line coil structures to combine by valve side low pressure winding, valve side low pressure winding connects winding by valve side low pressure star and valve side low pressure corner connection winding constitutes, net side high pressure winding is first winding, valve side low pressure winding is second winding, feature is the fine tuning winding, coarse adjustment winding and string become a winding and constitute the tertiary winding, fine tuning winding and coarse adjustment winding are cascaded by fine tuning winding contact, and fine tuning winding and coarse adjustment winding become a winding power supply for string jointly.
The utlity model has and under the situation of not cutting off the power supply, to adopt tertiary winding voltage regulating mode to realize on a large scale that continuous voltage regulating requires, realizes that separate unit 12 export mutually and need not no-load fall the advantage of section switch.
