Description

Technical Field

[0001] The utility model relates to the field of confluence equipment, in particular to a protective structure and a confluence cabinet. Background Art

[0002] In order to improve the heat dissipation effect, the combiner cabinet usually has openings on both sides of the cabinet for ventilation and heat dissipation. However, when it rains, rainwater can easily enter the cabinet through the air inlet and heat dissipation port, affecting the components inside the cabinet.

[0003] In order to prevent rain or water vapor from entering the cabinet, dust filters and dust filters need to be installed on the fresh air inlet and heat dissipation outlet, and the dust filters and dust filters need to be replaced regularly.

[0004] Due to the high voltage in the combiner cabinet, when replacing the dust filter and dust filter cotton, the electrical components in the combiner cabinet may be touched, thus causing safety hazards. Although locking the blinds can prevent unauthorized personnel from touching the blinds, on the one hand, there are still safety hazards when the staff replaces them, and on the other hand, locking increases the relevant costs and makes the dust filter and dust filter cotton procedures more cumbersome.

[0005] How to reduce the risk of electric shock and improve the replacement efficiency of dust filters and dust filter cotton is an urgent problem to be solved. Utility Model Content
