Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] If the electronic power transformer is not monitored in real time during operation, it will not be able to be discovered and controlled in time when a situation occurs, causing a greater impact. The parameters of the transformer can be changed by adjusting the number of turns, and the parameters of the transformer can be changed by changing the control parameters of the transformer. , through the way of servo adjustment, the adjustment accuracy is improv...

Abstract

The invention discloses a control method and a control system of an electronic power transformer, which relate to the technical field of electronic power transformers. The control method of the electronic power transformer comprises three steps of presetting a normal parameter value range, carrying out real-time monitoring on using parameters of a high-voltage transformer and making reactions, candiscover problems timely, take corresponding measures and remind the staff. The control system of the electronic power transformer comprises an AC power source, wherein an output end of the AC powersource is connected with an input end of a relay by means of a lead wire, an output end of the relay is connected with an input end of a voltage regulator by means of a lead wire, an output end of thevoltage regulator is connected with an input end of the high-voltage transformer by means of a lead wire, and an output end of the high-voltage transformer is connected with an input end of a rectifier by means of a lead wire. The composition structures are few, the cooperation efficiency among the structures is high, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power transformer control, in particular to a control method and system for an electronic power transformer. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power user distribution; test transformers can withstand voltage (boost) for electrical equipment Test equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems (PT, CT); special-purpose transformers include electric furnace transformers for smelting, welding transformer...
