Technical Field

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

[0002] A ring main unit is an electrical device that is assembled in a cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses. It has the advantages of improving power supply parameters, performance and safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] The ring main unit is equipped with power monitoring equipment for monitoring electricity. Due to factors such as environmental weather, there will be a large amount of water vapor in the cabinet. Under the action of cooling equipment such as air conditioners, the water vapor will condense into water droplets on the power monitoring equipment. These water droplets will corrode the power monitoring equipment under the action of electricity, causing equipment short circuit and affecting the normal operation of the power equipment.

[0004] For example, the primary and secondary integrated ring network cabinet disclosed in Chinese patent CN211701227U is provided with an isolation mechanism to isolate the cabinet from the cable trench, prevent water vapor in the cable trench from entering the cabinet, improve the dryness in the cabinet, and ensure the normal operation of the equipment in the cabinet; a dehumidification mechanism is provided to prevent water vapor in the cabinet from adhering to the power equipment in the cabinet, avoid water vapor corroding the power equipment under the action of electricity, causing damage to the power equipment and affecting the normal operation of the power equipment. At the same time, the dehumidification mechanism can be used repeatedly, has good dehumidification effect, simple structure and easy operation.

[0005] However, the ring main unit does not have a heat dissipation structure inside, so the heat generated by the ring main unit during operation cannot be discharged in time, which may cause the components in the ring main unit to overheat and be damaged.

[0006] For this purpose, we urgently need to provide an integrated primary and secondary fusion ring main unit with heat dissipation function. Utility Model Content
