Stereoscopic rolling iron core intelligent transformer

Abstract

The invention discloses a stereoscopic rolling iron core intelligent transformer which comprises a stereoscopic rolling iron core transformer and an intelligent control system. The intelligent control system comprises an on-load tap changer, a control circuit and a data collection circuit. The voltage regulating coil tap on the high-voltage side of the stereoscopic rolling iron core transformer is connected with the on-load tap changer, the on-load tap changer is connected with the control circuit, and the control circuit is connected with the data collection circuit. According to the stereoscopic rolling iron core intelligent transformer, the intelligent control system is added to an original stereoscopic rolling iron core transformer, in the intelligent control system, the data collection circuit collects signals, and the control circuit generates control signals according to collected signals to control the action of the on-load tap changer. When the transformer runs, the transformer can be directly adjusted to be connected separately, constant output voltage in a reference range can be supplied by the transformer when a load changes, power consumption is reduced, and electricity consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a three-dimensional wound core intelligent transformer. Background technique [0002] With the development of the power industry and the improvement of the country's agricultural power grid renovation project, the low voltage at the end of the power grid has been generally improved. However, the ensuing problem is that the grid voltage is generally high. At present, the output voltage of the transformer is designed to be 400V according to the standard. However, due to the load fluctuation of the voltage of the grid line and the distance of the line, the output voltage of the transformer is constantly changing. It is a common phenomenon that the voltage rises to 420V. The use of electricity has caused a lot of waste. According to the data recorded by 10 Class D voltage monitoring points in a certain area of ​​Zhejiang Province in two months: the time of ultra-high voltage r...

However, the ensuing problem is that the grid voltage is generally high

At present, the output voltage of the transformer is designed to be 400V according to the standard. However, due to the load fluctuation of the voltage of the grid line and the distance of the line, the output voltage of the transformer is constantly changing. It is a common phenomenon that the voltage rises to 420V. The use of electricity has caused a lot of waste

According to the data recorded by 10 Class D voltage monitoring points in a certain area of ​​Zhejiang Province in two months: the time of ultra-high voltage reaches 50.5%, the time of ultra-low reaches 1.4%, and the qualified time is only 48.1%, especially in the electricity load It is also a common phenomenon that the voltage rises from 380V to 450V during the valley, resulting in increased loss in the power grid and a low pass rate of power supply quality

The power consumption of the enterprise's power transformer and all related equipment increases and the motor is often burned out, reducing the service life of the equipment and increasing maintenance and repair costs
