Abstract

The invention discloses an intelligent power grid transformer substation relay protection tester with good heat dissipation. The tester comprises a shell. An internal circuit is arranged in the shell. A front panel of the shell is provided with a LED display screen (1), sixteen paths of simulation signal output ports (2) and a button (3). A left panel of the shell is provided with four pairs of switching value input ports A (4), eight pairs of switching value output ports (5), an Ethernet interface (7), a circular heat dissipation window (8), a power supply interface (9) and a power switch (10). A right panel of the shell is provided with four pairs of switching value input ports B (11), twelve paths of optical network ports (12) and twelve paths of optical serial ports (13). The internal circuit comprises a central processor, a digital signal processor, a digital-analog conversion circuit, a second-order filter circuit, a power supply circuit, a first network card and a second network card. The left panel is provided with the circular heat dissipation window and a rear panel is provided with a heat dissipation window in a shutter shape. A good heat dissipation effect is possessed.

Description

technical field [0001] The invention relates to the technical field of substation relay protection testers, in particular to a smart grid substation relay protection tester with good heat dissipation. Background technique [0002] With the rapid development of the power industry, the requirements for the substation relay protection tester, which is an important test tool used to ensure the safe and reliable operation of the power system, are also getting higher and higher. The substation relay protection tester will generate a lot of heat during work. If the heat cannot be dissipated in time, the temperature of the tester will rise, which will affect the normal operation of the components inside the tester, resulting in inaccurate test results. . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a smart grid substation relay protection tester with good heat dissipation, which has good heat...
