Embodiment Construction

[0017] In the following, the technical features of the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] A low-voltage power supply system fault diagnosis training device, such as figure 1 As shown, it is composed of three-phase isolation transformer 1, three-phase circuit breaker 2, simulated fault terminal 3, simulated load 4, switch 5, grounding plate 6, simulated grounding resistor 7 and other components, and the components are connected by connecting wires.

[0019] The three-phase circuit breaker 2 is an air circuit breaker with short circuit, overload and leakage protection.

[0020] The simulated fault terminal 3 is a set of adjustable resistors with a resistance value ranging from 100Ω-∝, which can be switched arbitrarily during use according to the requirements of the training content.

[0021] The simulated load 4 is three groups of electromagnetic coils with adjustable impedance values, and...

Description

technical field [0001] The invention relates to the technical field of electrician teaching and training, in particular to a low-voltage power supply system fault diagnosis training device. Background technique [0002] In the field of electrician teaching and training technology, especially the teaching of power supply system fault analysis, due to the lack of corresponding training devices to reproduce the phenomena and parameters before and after fault repair, it can only be completed by means of logical analysis and inference based on theory. The theoretical basis and practical experience requirements of students and trainees are relatively high, the teaching is difficult, and the teaching process is relatively boring. Therefore, this kind of teaching is difficult and inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-voltage power supply system fault diagnosis training device, a functional el...
