ZPSC-type phase shift rectifier transformer

Abstract

The invention provides a ZPSC-type phase shift rectifier transformer which comprises a transformer base, an upper clamp part, a lower clamp part, supporting strip, a cooling air channel, a cooling fan and a winding. The winding comprises an iron core, a low-voltage coil including a main winding and a phase shift winding, an epoxy resin cylinder and a high-voltage coil, the low-voltage coil, the epoxy resin cylinder and the high-voltage coil are sequentially arranged on the outer side of the iron core, the low-voltage coil and the high-voltage coil can be wound according to relevant required sizes during winding, and both the upper clamp part and the lower clamp part are provided with reinforcing plates. The ZPSC-type phase shift rectifier transformer is characterized by also comprising a low-voltage coil outgoing head, wherein the low-voltage coil outgoing head is an 8-shaped woven outgoing head, and the low-voltage coil is arranged in the low-voltage coil outgoing head. The ZPSC-type phase shift rectifier transformer is convenient to use and easy to process, has the advantages of being low in temperature rise, low in partial discharge level, low in loss, strong in overload capacity and the like and can be manufactured in a unique structural form according to the transformer size demand of a customer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a ZPSC type phase-shifting rectifier transformer. Background technique [0002] Phase-shifting rectifier transformer is a kind of rectifier transformer. It is not only a kind of important factory and mine electrical equipment, but also can be used as a precision instrument in measuring room and laboratory. [0003] The rectifier transformer is the power transformer of the rectifier equipment. The characteristic of the rectifier is that the primary side inputs AC, and the secondary side outputs DC after rectifying the original. Converter is the general term for the three working modes of rectification, countercurrent and frequency conversion, and rectification is the most widely used one. A transformer used as a rectifier power supply is called a rectifier transformer. Most of the rectified DC power supplies used in industry are obtained from the AC grid through rectifier ...
