Abstract

The invention discloses a relay protection tester based on an embedded system, and a checking method for the relay protection tester. The tester comprises the embedded system based on an advanced RISC machine (ARM11), a display screen, keyboard and mouse equipment, a printer, a global positioning system (GPS) positioning device and a global packet radio service (GPRS) communication interface, wherein the embedded system based on the ARM11 is connected with the display screen, the keyboard and mouse equipment, the printer, the GPS positioning device and the GPRS communication interface respectively, controls power through a universal serial bus (USB) or an Ethernet interface and is connected with a relay protection device through an RS232 interface. By the tester and the checking method, experiment current can be calculated; test current output by the relay protection tester can be controlled; after the protection device runs, running data are received by the RS232 interface of a device panel, and a result is compared with a theoretical value; and therefore, correctness of running can be judged. By using the relay protection tester, each main transformer protection checking time can be averagely shortened by 1 hour.

Description

technical field [0001] The invention belongs to the technical field of relay protection, and relates to a test device for contrast ratio braking protection, in particular to a relay protection tester based on an embedded system and a test method thereof. Background technique [0002] Existing inspections of relay protection ratio brakes generally use manual methods, that is, use a general-purpose relay protection tester to simulate fault conditions to set output electrical parameters, monitor the action of protection devices, verify protection functions and customize settings. Check whether it is correct, and then record the inspection results in the commissioning report. [0003] There are some deficiencies in this existing inspection method: [0004] Excessive reliance on the technical capabilities of individual staff members. On-site staff must fully understand the ratio brake inspection function, calculate its action characteristics according to the protection setting ...
