Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of signboard, concretely is a transformer substation maintenance signboard. BACKGROUND

[0002] In the daily maintenance and overhauling of transformer substations, maintenance signboards are important equipment for ensuring the safety of operating personnel. The existing transformer substation maintenance signboards usually adopt a simple pole type structure, are supported by a base, and have warning signs installed on the top for reminding relevant personnel of safety matters and operating states. Such signboards play an indispensable role in the daily operation and maintenance of power systems and are basic facilities for ensuring the normative and safety of maintenance operations.

[0003] However, the transformer substation maintenance signboards on the market have many deficiencies. First, the connection mode between the signboard and the support structure is single, and simple bolt fixation or welding is usually adopted, which is prone to loosening and tilting, affecting the service life. Second, the traditional signboard is inconvenient to replace, and the fixed structure needs to be repeatedly disassembled and assembled, which not only consumes time and effort but also easily damages the fixed parts. Third, the existing signboards are mostly designed on one side, and the information display is limited, which is insufficient in function under the demand of multi-directional warning. In addition, the stability of the traditional signboard is poor, and it is prone to falling in bad weather, which not only affects normal use but also has safety hazards. These problems seriously restrict the efficiency and safety of maintenance operations in actual application.

[0004] Therefore, there is an urgent need for a transformer substation maintenance signboard with stable structure, convenient installation, good information display effect and anti-falling function to improve the safety and efficiency of transformer substation maintenance operations and meet the growing safety maintenance needs of power systems.
