Description
Technical Field
[0001] The present invention relates to the technical field of ring network cabinets, in particular to an outdoor water-proof ring network cabinet. Background Art
[0002] Ring main unit is a group of electrical transmission and distribution equipment installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core parts use load switches and fuses. It has the advantages of simple structure, small size, low price, and can improve power supply parameters and performance as well as power supply safety.
[0003] Ring main units are used in urban distribution networks, industrial distribution networks and rural distribution networks. Urban distribution network ring main units are mainly used in urban residential areas, commercial areas and other areas with high requirements for power quality and reliability. Industrial distribution networks are mainly used in industrial fields such as factories and mines. Rural distribution ring main units require equipment to be wind-resistant, lightning-resistant, waterproof and moisture-proof.
[0004] A ring network refers to a circular distribution network, where the power supply trunk forms a closed ring. The power supply feeds this ring trunk, and then distributes power to the outside through high-voltage switches. The advantage of this is that each distribution branch can draw power from both the trunk to its left and the trunk to its right. When the left trunk fails, it continues to receive power from the right trunk, and when the right trunk fails, it continues to receive power from the left trunk. In this way, although the total power supply is single-circuit, each distribution branch benefits from dual-circuit power supply, thereby improving the reliability of power supply.
[0005] The so-called "ring network cabinet" means that each distribution branch is equipped with a switch cabinet (outgoing line switch cabinet). The busbar of this switch cabinet is also part of the ring trunk line. That is to say, the ring trunk line is composed of the busbars of each outgoing line cabinet connected together. Each outgoing line cabinet is called a "ring network cabinet". In fact, if you take out a ring network cabinet alone, you cannot see the meaning of "ring network".
[0006] The rated current of these ring network cabinets is not large, so the high-voltage switch of the ring network cabinet generally does not use a complex circuit breaker but a simple high-voltage load switch with a high-voltage fuse. In other words, the high-voltage switch in the ring network cabinet is generally a load switch. The ring network cabinet uses the load switch to operate the normal current and the fuse to cut off the short-circuit current. The combination of the two replaces the circuit breaker. Of course, this can only be limited to a certain capacity.
[0007] Such switchgear can also be used in non-ring network distribution systems. With the widespread application of this type of switchgear, the term "ring network cabinet" has jumped out of the scope of ring network distribution and generally refers to high-voltage switchgear with load switches as the main switches.
[0008] The ring main unit is an electrical equipment of the ring network power supply unit that is environmentally friendly, fully insulated, fully enclosed, easy to operate and reliable in operation. All conductive parts in the switch are installed in a sealed stainless steel gas box. The gas box uses dry air as the main insulation body. The main switch adopts vacuum arc extinguishing and the disconnector adopts a three-position structure. It is equipped with the State Grid Power Internet of Things system, which can realize the deep integration of primary and secondary equipment, namely "intelligent primary equipment, networking of secondary equipment, unmanned operation and maintenance management" and "health management" of the entire life cycle of distribution equipment, truly establishing an "unmanned and manned" power digital ecology.
[0009] At present, the existing ring network cabinets are unable to perform multiple safety protection measures when in use. At the same time, improvements are needed to address the problem of water immersion. When the water level is high, height adjustment is required to prevent the ring network cabinet from being affected. Summary of the Invention
