Problems solved by technology

[0003] In the process of grounding the existing transmission line, the grounding state is not detected, and the transmission line is directly buried in the ground. Long-term soil erosion and the tension of the transmission line may easily cause the incomplete grounding of the transmission line, thus affecting the operation of the transmission line. safety

Abstract

The invention discloses a power transmission line grounding state intelligent sensing device. The device comprises a base, a sleeve is fixedly installed in the middle of the top end of the base, a sleeve rod is sleeved with the sleeve, a grounding ring is fixedly installed at the top end of the sleeve rod, a connecting wire is wound around and connected to the surface of the grounding ring, and aground pile is fixedly installed at the bottom end of the sleeve rod. The ground pile is connected with the center of the base in a penetrating mode, lifting mechanisms are fixedly arranged on the twosides of the sleeve, an alarm lamp is fixedly installed at the corner of one side of the top end of the base, a ground fault sensor is fixedly installed in the middle of one side of the top end of the base, and a display screen is fixedly installed on one side of the base. According to the invention, through the installed grounding fault sensor, whether the power transmission line is grounded ornot can be conveniently detected, the detected data is processed through the PLC and is distinguished through different colors of the alarm lamp, and the grounding of the power transmission line is ensured.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to an intelligent sensing device for the grounding state of a power transmission line. 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 form, transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and are erected on the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. [0003] In the process of grounding the existing transmission line, the grounding state is not detected, and the transmission line is directly b...
