Description

Technical Field

[0001] The utility model belongs to the technical field of electric power safety equipment, in particular to an insulation line grounding device. Background Art

[0002] Insulated conductors are evenly and tightly coated with a non-conductive material, such as resin, plastic, silicone rubber, or PVC, to form an insulating layer that prevents contact between the conductor and the outside world, potentially causing leakage, short circuits, and electric shock. Insulated conductors offer high safety and are commonly used in high-voltage transmission lines.

[0003] During the inspection and maintenance of high-voltage transmission lines, insulated cables must be grounded to ensure the safety of workers. Current methods of grounding insulated conductors require first removing the insulation sheath from the conductor, then clamping a grounding clamp onto the exposed core of the conductor. However, the exposed core has low tensile strength and is prone to breakage due to metal fatigue at the ends, seriously impacting power transmission.

[0004] The utility model patent application number CN201220288935.0 discloses a grounding connection device, which simultaneously tightly connects the exposed core section of the cable and the cable insulation sleeves at both ends of the exposed core of the cable, thereby improving the tensile strength of the cable and extending the service life of the cable. However, when in use, this patent requires workers to climb the pole when the cable is energized and complete the installation of the device at a height, which increases the construction risk for workers and has poor construction safety. In addition, high-voltage transmission lines are often long, and multiple grounding devices need to be installed on the cable when grounding, which will greatly increase the probability of workers accidentally touching the live line, making it difficult to ensure the personal safety of workers. Therefore, there is an urgent need to provide a grounding device that can solve the above problems. Utility Model Content
