Anti-lightning electric power transformer

Abstract

The invention relates to the technical field of transformer equipment, and discloses an anti-lightning electric power transformer, which includes telegraph poles. The lower part of the front side of the telegraph pole is fixedly equipped with a support frame; a transformer is fixedly installed on the middle part of the upper surface of the support frame and is located between the two telegraph poles; a low-voltage bushing is fixedly installed on one side of the upper surface of the transformer; and a protection switch box is fixedly installed on one side of the telegraph pole, and the protection switch box is electrically connected with the low-voltage bushing. Compared with the prior art, coils are arranged on the side between each two layers of spark gap, the other side corresponding tothe coils is provided with a barrier plate, a passage is formed in a lightning arrester after lightning strike, each coil generates electromagnetism to attract the barrier plate, and the barrier platedirectly divides the arc, thus accelerating the extinction of arc, solving the problem of long-term arc damaging the spark gap and nonlinear resistance, and prolonging the service life of each component in the lightning arrester.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a power electrical transformer with lightning protection. Background technique [0002] A power electrical transformer is a static electrical device used to transform voltage and current to transmit AC power. It is used to convert a certain value of AC voltage and current into another or several different voltages with the same frequency. Current equipment and power transformers are prone to lightning strikes in thunderstorms, which can cause damage to power transformers. This requires a power transformer that can prevent lightning strikes. [0003] Refer to the attached Figure 1-2 , on the outdoor utility pole 1, the support frame 2 is fixedly installed to fix the transformer 3, the low-voltage bushing 4 on the transformer 3 is electrically connected to the protection switch box 5 to control the power on and off of the transformer 3, and the high-voltage bushing o...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a lightning-proof electric power transformer, which has the advantages of preventing rainwater from getting wet and quickly extinguishing the arc, and solves the problem that the straight tube is easy to enter water, and the arc between the spark gaps after the lightning strike will not problem that goes off quickly
