Phase-shifting filter transformer

Abstract

The invention discloses a phase-shifting filter transformer which comprises a base and a transformer body, T-shaped blocks are fixedly connected to the positions, close to the left side and the right side, of the outer surface of the upper end of the base at equal intervals, the transformer body is arranged on the outer surface of the upper end of the base, and a fixing mechanism is fixedly connected to the outer surface of the lower end of the transformer body; a bottom plate is fixedly connected to the outer surface of the lower end of the transformer body, and a fixing groove is formed in the position, close to the center, of the outer surface of the lower end of the bottom plate, the transformer can be carried without a lifting device during installation, so that the cost budget is reduced, meanwhile, the transformer can be conveniently matched with fixing devices with different intervals, the practicability of the transformer is improved, meanwhile, the transformer can be protected, accumulation of rain and snow can be effectively prevented, the safety and stability of the transformer are improved, the device can be ventilated when used in summer, the problem of circuit damage caused by internal overheating is solved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of transformer devices, in particular to a phase-shifting filter transformer. Background technique [0002] During the power supply process of the transformer, factors affecting the power quality of the system such as surges, instantaneous currents, and high-order harmonics often occur in the line; when the transformer is used in an inductive load, the inductive load is often affected by eddy currents and high-order harmonic components. impact, resulting in a large amount of power loss. The phase-shifting filter transformer can significantly improve the three-phase unbalance, improve the power factor and the utilization rate of electric energy, and is widely used in fields with high energy consumption such as steelmaking, textile, chemical industry, and machinery. [0003] Because steelmaking, textile, chemical industry, machinery and other fields generally require large transformers, there are the followin...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the large size of the transformer, when the transformer is installed and transported, it needs to be installed with a crane and a lifting device, which not only wastes resources but also increases the installation cost, making the installation not convenient enough; and for the existing different specifications When the transformer is installed, since the distance between the fixed crossbars on the base is fixed, it cannot be applied to transformers of different sizes, which makes the versatility poor and reduces the practicability of the device;

[0005] 2. Due to the large size of the transformer, a large amount of ice and snow will accumulate on the top of the transformer when it encounters rainy and snowy weather for a long time, which will easily cause damage to the transformer and increase the maintenance cost
