Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a primary and secondary fusion ring network cabinet. Background Art

[0002] A ring main unit is an electrical device installed in a cabinet and made into an assembled interval ring main unit. The primary and secondary integrated ring main unit integrates the functions of the primary and secondary sides to achieve multiple functions such as power distribution, protection, control and measurement. The primary and secondary integrated ring main unit is installed indoors or outdoors and is widely used in places with relatively high power supply reliability.

[0003] When the primary and secondary integrated ring network cabinet is installed outdoors and it rains outdoors, the cabinet exchanges air with the outside world through the air vents, so that the air flow can drive rainwater into the cabinet through the air vents. The long-term accumulation of rainwater may cause damage to the electrical components inside the cabinet, making it difficult for the electrical components to perform basic functions and causing certain losses.

[0004] For example, in a primary and secondary integrated ring network cabinet disclosed in Chinese patent CN220291394U, when it rains, the limiting structure does not restrict heavy objects, so that the heavy objects can smoothly drive the rain shield to cover the heat dissipation holes, making it difficult for rainwater to enter the cabinet through the heat dissipation holes, allowing the electrical components inside the cabinet to work normally, and blocking the opening of the limiting groove on the shielding plate, making it difficult for external sand and debris to enter the limiting groove through the perforations, so that the debris will not accumulate in the limiting groove, thereby affecting the sliding of the limiting bar in the limiting groove.

[0005] However, during the use of the device, dust will accumulate inside the heat dissipation holes, causing blockage of the heat dissipation holes and affecting the heat dissipation effect of the primary and secondary fusion ring network cabinet.

[0006] For this reason, we urgently need to provide a primary and secondary integrated ring main unit. Utility Model Content

[0007] The purpose of the utility model is to provide a primary-secondary fused ring network cabinet to solve the problem in the above background technology that dust accumulates inside the heat dissipation holes during use, causing blockage of the heat dissipation holes and affecting the heat dissipation effect of the primary-secondary fused ring network cabinet.
