Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment protection, and in particular to an outdoor cabinet operation and maintenance protection structure. Background Art

[0002] In power construction, outdoor cabinets are a common carrier of power equipment. Various electrical equipment are installed inside them, and the outdoor cabinet body provides protection and a good operating environment for the internal electrical equipment.

[0003] Under normal operating conditions, the outdoor cabinet is a fully enclosed structure that can effectively resist the adverse effects of severe weather conditions such as high and low temperatures, rain, snow, and dust on the equipment inside the cabinet. However, when it is necessary to operate and repair the equipment inside the cabinet, it is necessary to open the cabinet door for operation. At this time, the equipment inside the cabinet is exposed to the outdoor environment and is in a semi-protected state. Rainwater and dust from the outside are blown into the cabinet by the wind, which has a great impact on the normal operation of the equipment. In severe winter weather, external cold air enters the cabinet, and the optical cable pigtails in the cabinet are very likely to break and be damaged.

[0004] For traditional outdoor cabinets, when the maintenance personnel hold an umbrella to operate in rainy days, one person cannot complete the task alone. Two staff members are required to cooperate, one to hold the umbrella and the other to operate, which takes up human resources; the umbrella cannot completely cover the cabinet door. When there is heavy wind, rain or sand, rain or sand will be blown into the cabinet by the wind, affecting the safety of the equipment; and the umbrella cannot isolate the extremely cold temperature outside. The extremely cold air directly contacts the equipment and optical fiber in the cabinet, which is easy to form condensation. At the same time, the optical fiber is easy to break during operation;

[0005] For traditional outdoor cabinets, the traditional solution also sets up an external awning, but the external awning is heavy, inconvenient to move, and cannot be placed by one person; the storage of the external awning requires additional space, and for outdoor cabinets used in substations and urban public spaces, no additional storage space can be provided; the external awning is placed outdoors for a long time, and the material is prone to aging and rusting, requiring regular maintenance or replacement, which increases costs.

[0006] Traditional solutions also involve increasing the size of the cabinet to allow maintenance personnel to enter the cabinet for operation. Although this can solve the protection problem during operation and maintenance, the increase in cabinet size will significantly increase the cabinet manufacturing cost and the cabinet footprint. When personnel enter the cabinet for operation and maintenance, they also need to close the cabinet door. Once a safety accident occurs, it is inconvenient to open the cabinet door and personnel cannot escape quickly. Moreover, after the cabinet door is closed, if the lock fails, personnel may be accidentally locked in the cabinet. Summary of the invention

[0007] The purpose of the present invention is to solve at least one technical problem in the background technology and to provide an outdoor cabinet operation and maintenance protection structure.
