Description

Technical Field

[0001] The utility model relates to the field of electrical testing and grounding operations, and in particular to an intelligent grounding electrical testing system. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Ensuring the safe operation of power facilities is a crucial task in modern power system operation and maintenance. Electrical testing and grounding are crucial for ensuring the safety of workers and the stability of power equipment. Traditional manual testing and grounding procedures are not only time-consuming and labor-intensive, but also pose significant safety risks. This is particularly true for high-altitude work environments, such as transmission line tower inspections. Workers must manually climb the tower carrying a tester and grounding wire. This process is not only inefficient but can also lead to electric shock accidents due to improper operation, seriously threatening the lives of workers.

[0004] At the same time, with the rapid development of the Internet of Things, big data, and intelligent sensing technologies, the intelligent upgrade of power operations and maintenance has become an urgent need for industry development. In recent years, the increasing application of remote monitoring and automation technologies has provided new ideas and technical foundations for solving the challenges of high-altitude electrical testing and grounding operations. Although some rudimentary intelligent monitoring devices have appeared on the market, most of them are limited in function or complex in operation, failing to meet the requirements of efficient, safe, and integrated operations. In particular, they lack real-time data analysis, automatic warnings, and flexibility.

[0005] Currently, there are several existing grounding methods:

[0006] 1. Manually lift the grounding rod and the test rod, and manually stretch the insulating rod to perform the test and grounding operations;

[0007] 2. Mount the grounding device on the drone for grounding.

[0008] However, the above existing grounding methods have the following problems:

[0009] 1. When the line voltage level is high, the use of conventional grounding rods and test rods is cumbersome and time-consuming. They are also heavy and labor-intensive.

[0010] 2. Mounting a grounding device on a drone for grounding and electrical testing requires professional pilots to operate, and its application scope is limited. For example, it is not easy to operate in complex scenarios such as substations with many equipment and lines. Utility Model Content
