Abstract

The invention discloses a safety protection platform for testing transmission line parameters, which comprises a line parameter tester, a first head end safety switching device, a second head end safety switching device, a first opposite end safety switching device, a second opposite end safety switching device and a PC, wherein the first head end safety switching device and the second head end safety switching device are both connected with the head end of a tested line and used for collecting real-time induced voltage of the line; the first head end safety switching device and the second head end safety switching device are both connected with the line parameter tester through RS485 serial port cables and used for transmitting collected line real-time induced voltage data to the line parameter tester and receiving test switching instructions sent by the line parameter tester. The safety protection platform is ingenious in concept, avoids the personal electric shock risk caused by induction electricity and lightning in the testing process from the technical aspect, avoids the safety risk caused by illegal operation and misoperation of operators, and achieves the whole-process intelligent testing.

Description

technical field [0001] The invention relates to the technical field of transmission line parameter testing, in particular to a transmission line parameter testing safety protection platform. Background technique [0002] The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. In the 1880s, DC transmission was first successfully realized. However, because the voltage of DC transmission was difficult to continue to incre...
