Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically relating to a novel grounding resistance reduction device for distribution network lines. Background Technology

[0002] Grounding is a technology that uses a conductor to discharge electrical charges above the ground potential to the earth. People and objects are all supported by the earth, which is a good conductor. Generally speaking, the earth's potential is set to zero voltage, also known as the ground potential. Voltages higher than the ground potential, if passing through people or objects, can cause harm to people or damage to objects. Therefore, grounding has become a widely used technology in various aspects of industrial production and daily life, such as lightning protection for buildings and leakage protection for electrical appliance casings.

[0003] Existing grounding resistance reduction devices for distribution network lines can prevent damage from rainwater impact, thus ensuring the safe use of the resistance reduction device. However, in dry areas, the ground needs to be moistened to improve the conductivity of the soil and ensure the normal use of the resistance reduction device. In addition, it is inconvenient to connect multiple grounding blocks together during use, which reduces installation efficiency when multiple devices are required. Utility Model Content
