[0030] detailed description

[0031] The invention includes a host computer (generally a computer), a control machine, a housing, a mutual inductor located in the housing, and a number of analog wiring terminals located outside the housing.

[0032] Such as figure 1 As shown: the upper computer and the control machine are connected through the RS232 serial port, and each terminal is connected to the wiring socket of the control machine main board. The shell simulates a real voltage transformer shell, and the voltage transformer is arranged inside the shell.

[0033] The detailed introduction is given below.

[0034] 1. Voltage transformer

[0035] The voltage transformer in the shell is composed of a primary winding, a secondary winding, an iron core and insulation that are mutually insulated. Its working principle is basically the same as that of a transformer. When a voltage U1 is applied to the primary winding, a magnetic flux φ is generated in the core. According to the law of e...

Abstract

The invention provides a standard voltage transformer simulator which includes an upper computer, a control machine, a shell, a voltage transformer disposed in the shell, and a plurality of simulation wiring terminals disposed outside the shell, wherein the upper computer and the control machine are connected in a communication mode, and the control machine is connected with the simulation wiring terminals. According to the standard voltage transformer simulator, real-time simulation is carried out by the use of a computer to simulate the on-site working condition to the greatest extent, and under the condition that the appearance and functions of equipment are completely simulative, the input and output voltages are small, and reliable security guarantee can be provided for students in standard voltage transformer training examination under safe working voltage.

Description

technical field [0001] The invention relates to the field of electric energy transformers, in particular to a standard voltage transformer simulator. Background technique [0002] At present, domestic electric energy measurement and verification personnel have high mobility, slow knowledge update, uneven professional knowledge and work level, relatively few interdisciplinary talents, and few technicians who have mastered the on-site verification technology of transformers, which affects the normal detection work, mainly Because the training equipment is lagging behind, most of the training methods currently focus on theoretical training, demonstration experiments, written examinations, and on-site training, all of which have great limitations and the training efficiency is very low. [0003] Moreover, in the training in the actual environment, because the electric energy metering equipment has high voltage and high current, it will cause potential safety hazards to people an...
