Long-life ring main unit with multi-stage heat dissipation performance

Abstract

The invention discloses a long-life ring main unit with multi-stage heat dissipation performance. The long-life ring main unit comprises a ring main unit body, wherein ventilation pipelines are fixedly connected to two inner sides of the ring main unit body; air inlet holes are formed in the positions, corresponding to the bottom ventilation pipelines, of the top end of the ring main unit body; top filter screens are embedded into the inner sides of the air inlet holes; cooling fans are fixedly installed on the inner sides of the ventilation pipelines; and air guide openings are formed in the end faces of the two sides of the ventilation pipelines at equal intervals. The ring main unit is scientific and reasonable in structure and safe and convenient to use; a contact area between the ring main unit and air can be increased through aluminum heat dissipation blocks, so heat dissipation capacity is improved; after external air is sucked into the ring main unit body by the cooling fans, cold air is uniformly dispersed into the ring main unit body through the ventilation pipelines and the air inlet hole, so internal components are fully contacted with the air for heat dissipation; and then hot air containing heat is pumped out through the cooling fans, so heat dissipation effect is improved, and the service life of the ring main unit is prolonged.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a long-life ring network cabinet with multi-stage heat dissipation. Background technique [0002] The ring network cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It has the advantages of low price, improved power supply parameters and performance, and power supply security. It is widely used in distribution stations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises, box-type substations, and ring network cabinets. The high-voltage switch is generally a load switch. Such a ring network cabinet can also be used in a power distribution system with a non-ring netwo...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a long-life ring main unit with multi-stage heat dissipation, which can effectively solve the problem that the existing ring main unit proposed in the background technology will be cold during heat dissipation After the air blows into the inside of the ring network cabinet, the cold air will float around and cannot absorb heat evenly, resulting in poor heat dissipation performance of the ring network cabinet, and rapid aging of internal components, which reduces the service life of the ring network cabinet
