Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, in particular to a lightning protection device for a DC transmission control cabinet. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical equipment and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment.

[0003] According to a DC transmission control cabinet lightning protection device disclosed on the patent website (authorization publication number: CN 209881405U), "The present utility model discloses a DC transmission control cabinet lightning protection device, comprising a support tube and a DC transmission control cabinet body. A protective box is fixedly mounted at the end of the support tube. A screw is provided inside the support tube. The top end of the screw passes through the protective box and extends to the outside of the top end of the protective box and is fixedly connected to a handwheel for rotating the screw. A ratchet located inside the protective box is fixedly provided on the outer surface of the screw. A fixing mechanism for fixing the screw is provided on the inner wall on the right side of the protective box. The fixing mechanism consists of a limit rod, a handle, a limit block and a spring. The limit block is fixedly mounted on the outer surface of the limit rod, and the spring is arranged on the outer surface of the limit rod. The utility model drives the screw to rotate by rotating the handwheel, and the screw drives the connecting block to rise or fall, thereby adjusting the height of the lightning receptor. In addition, the lightning protection device can adjust the lightning protection range of the lightning receptor according to actual conditions, and the ratchet is fixed by providing a limit rod."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of the utility model, the handle is first pulled outward to separate the limit rod from the ratchet, and then the handwheel is turned to drive the screw rod to rotate through the handwheel, and the connecting block is driven to rise or fall through the screw rod, so as to adjust according to the actual position of the lightning rod. During actual use, the mounting plate hole position of the device is fixed, resulting in the inability to meet the installation and use requirements of different DC transmission control cabinets. At the same time, the placement position of the grounding down conductor of the device is only fixedly connected to the lightning rod, resulting in the interface fusing and other loosening during long-term use and the lightning induction process, thereby causing accidents. Therefore, it is necessary to improve a DC transmission control cabinet lightning protection device to solve the above problems. Utility Model Content
