Current transformer fault simulation training device

Abstract

The invention relates to a fault simulating training device of a current transformer. The device comprises a low-voltage current transformer body equipped with a tap, a wireless transmitter that is used in match, a wireless switch control driver and a housing; a fault simulating switch executing circuit, which is electrically connected with a wireless switch control driver, is arranged between a secondary side of the current transformer body and an output wiring terminal of the housing; a remote control transmitter is used for transmitting a fault control signal input by an operator to the wireless switch control driver by a wireless mode; the wireless switch control driver is used for receiving the fault control signal of the remote control transmitter; the control fault simulation switch executing circuit realizes transformation ratio switching simulation of the current transformer body, polarity adding and reducing switching simulation, exceeding impedance and normal impedance switching simulation, connection and disconnection switching simulation of the secondary side. With the adoption of the fault simulating training device of the current transformer, various site faults can be reproduced, the training efficiency is high, and the consistency with the site is high.

Description

technical field [0001] The invention relates to a teaching and training device, in particular to a current transformer fault simulation training device. Background technique [0002] The current transformer (TA) is a sensor for measuring and measuring instruments to obtain primary current information. That is to say, for the metering device, it is very important whether the wiring of the current 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] The current transformer (TA) is a sensor for measuring and measuring instruments to obtain primary current information. That is to say, for the metering device, it is very important whether the wiring of the current 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
