Voltage transformer fault simulation practical training device

Abstract

The invention relates to a voltage transformer fault simulation practical training device which comprises a low voltage transformer body and a wireless transmitter, a wireless switch control driver and a casing which are matched with the low voltage transformer body in use. An input terminal and an output terminal are arranged on the casing, a primary side fault simulation switch execution circuit is arranged between the input terminal of the casing and the primary side of the voltage transformer body, and a secondary side fault simulation switch execution circuit is arranged between the secondary side of the voltage transformer body and the output terminal of the casing, and the primary side fault simulation switch execution circuit and the secondary side fault simulation switch execution circuit are both electrically connected with the wireless switch control driver. The practical training device can reproduce various onsite faults, and is high in training efficiency and good in onsite consistency.

Description

technical field [0001] The invention relates to a teaching and training device, in particular to a voltage transformer fault simulation training device. Background technique [0002] A voltage transformer (TV) is a sensor for measuring and measuring instruments to obtain primary voltage information, that is, for a metering device, it is very important whether the wiring of the voltage transformer is correct. If there is a wrong wiring, the value of the metered electric energy will change and cannot be normal. Metering, even impossible to measure, will cause damage to instruments and equipment in severe cases; what is more serious is wrong wiring at the transformer, which is likely to cause equipment damage or personal injury or death.

[0002] A voltage transformer (TV) is a sensor for measuring and measuring instruments to obtain primary voltage information, that is, for a metering device, it is very important whether the wiring of the voltage transformer is correct. If there is a wrong wiring, the value of the metered electric energy will change and cannot be normal. Metering, even impossible to measure, will cause damage to instruments and equipment in serious cases; what is more serious is wrong wiring at the transformer, which is likely to cause equipment damage or personal injury accidents

The current training equipment mainly includes real equipment consistent with the actual equipment on site and intelligent simulation training equipment, but these two types of equipment have serious deficiencies in training:

The most obvious shortcomings are that failures cannot be reproduced, it is not convenient to learn the principles, the training efficiency is extremely low, and the lack of comprehensiveness and theoreticalness of professional knowledge

[0004] 2. The existing intelligent simulation training system: the boring and monotonous human-machine interface lacks a sense of reality, the most prominent problem is the poor consistency with the site, and the operation training of installation and wiring cannot be carried out

The trainers cannot fully understand the wiring of the device as a whole, and its internal structure is very different from that of the site, so it cannot arouse the trainers' strong interest in learning, and they cannot actively understand and learn the situation and reasons for the wrong wiring on site
