A zps phase-shifting rectifier transformer

Abstract

The invention provides a ZPS-type phase shift rectifier transformer which comprises an oil tank, transformer oil, a base, a low-voltage sleeve, supporting strips, a high-voltage sleeve, a tap switch, an expansion tank, an explosion-proof pipe, an oil level gauge, a cooling oil channel and a winding. The winding comprises an iron core, a low-voltage coil including a main winding and a phase shift winding and a high-voltage coil, the low-voltage coil 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, the oil tank is full of transformer oil, the iron core is arranged in the oil tank, a tank cover is arranged at the top of the oil tank and is in sealed connection with the oil tank, the low-voltage sleeve, the high-voltage sleeve, the tap switch, the expansion tank and the oil level gauge are arranged on the tank cover, the low-voltage coil is connected with the low-voltage sleeve on the tank cover, the high-voltage coil is connected to the tap switch on the tank cover and then is connected with the high-voltage sleeve, an epoxy lining cylinder and a plurality of supporting strips are arranged in the low-voltage sleeve, the supporting strips are arranged between the cooling oil channel and the epoxy lining cylinder, and the supporting strips are arranged between the epoxy lining cylinder and the low-voltage coil.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a ZPS 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 t...
