Description

Self-adaptation looped netowrk cabinet with rain-proof snow function

Technical Field

The invention relates to the field of ring main units, in particular to a self-adaptive ring main unit with rain and snow prevention function.

Background

The ring main unit is a group of electric equipment which is arranged in a metal or nonmetal insulating cabinet body or is made into an assembled interval ring main power supply unit, and the core part of the ring main unit adopts a load switch and a fuse, so that the ring main unit has the advantages of simple structure, small volume, low price, capability of improving power supply parameters and performance, power supply safety and the like. The transformer substation is widely applied to distribution stations and box-type substations of load centers of urban residential districts, high-rise buildings, large public buildings, factory enterprises and the like.

The ring network is a ring distribution network, namely a power supply main line forms a closed ring, a power supply supplies power to the ring main line, and the power is distributed outwards from the main line through a high-voltage switch all the way. This has the advantage that each power distribution branch can take power from both its left and right side rails. When the left main line fails, the left main line is continuously supplied with power from the right main line, and when the right main line fails, the right main line is continuously supplied with power from the left main line, so that the utility of the total power supply is similar to that of the two-way power supply, although the total power supply is one-way power supply, and the reliability of the power supply is improved.

The looped netowrk cabinet arranges outdoor usually, generally speaking, rainwater erosion can cause serious threat to each electrical apparatus in the looped netowrk cabinet, consequently to the looped netowrk cabinet, each electrical apparatus of its inside can accumulate a large amount of heats at the in-process of work, these heats in case can't normally give off will cause the electrical apparatus long time to work under high temperature, very easily influence the life of electrical apparatus, consequently to the looped netowrk cabinet, need lay the thermovent and carry out supplementary heat dissipation to electrical apparatus in the looped netowrk cabinet, and these louvres provide convenience for the erosion of rainwater again, influence the normal use of looped netowrk cabinet.
