The invention discloses a portable relay protection fixed value setting simulation training device. A control circuit and a storage battery are arranged in a shell. The shell comprises an upper shell body and a lower shell body. A liquid crystal display screen, a control keyboard and an ISP download interface are arranged on a front panel of the upper shell body. A touch screen, a JTAG download interface and a charging interface are arranged on a front panel of the lower shell body. The control circuit comprises a signal chip microcomputer circuit, a JTAG interface circuit, a power circuit, a microcontroller U1, an ISP interface circuit and a touch screen driving circuit. The microcontroller U1 is connected with a plurality of keys of the control keyboard and further connected with an external crystal oscillator circuit and a reset circuit. The portable relay protection fixed value setting simulation training device has the advantages that the problem that special training rooms need to be built when fixed value setting training is conducted on staff in the prior art is solved, relay protection fixed value setting training can be conveniently conducted on the staff, the cost is low, and human and material resources are saved.
Description
technical field [0001] The invention relates to a portable relay protection fixed value setting simulation training device. Background technique [0002] With the rapid development of science and technology, the application of relay protectors in substations is becoming more and more extensive. It not only protects the safety of the equipment itself, but also ensures the normal production. Therefore, it is very important to do a good job in the setting of relay protection to ensure the safety of equipment and the normal operation of production. [0003] Relay protection devices (including safety automatic devices) are the most basic, important and effective means to ensure the safety of power equipment and the stability of power systems. The correct actions of relay protection devices have saved and guaranteed the safe and stable operation of the power system countless times. However, this is also a double-edged sword. Once the relay protection device operates incorrectly,...
