Ring main unit with high adaptability

Abstract

The invention discloses a ring main unit with high adaptability, belonging to the technical field of ring main units. The ring main unit with high adaptability comprises a cabinet body and a fixed plate. According to the ring main unit with high adaptability, a motor is started, the motor drives a heat dissipation fan to extract external air, and a filter screen can filter the air about to enter the body of the ring main unit; the air enters the body of the ring main unit, can flow in a curve shape in the body of the ring main unit through fixing strips and wind blocking strips and makes full contact with ta he fixing plate and electronic components to absorb heat; and then the air having absorbed the heat is discharged out of the body of the ring main unit through an air inlet hole. Meanwhile, a water pump is started, the water pump pumps and inputs cooling liquid cooled by cooling fins in a heat dissipation box into the heat absorption box to absorb the heat in the body of the ring main unit, and then the cooling liquid flows into the heat dissipation box and is cooled through the cooling fins. The heat of the body of the ring main unit can be fully dissipated through the above two efficient heat dissipation modes, so the body of the ring main unit can still work normally in a hot environment.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a ring network cabinet with strong adaptability. Background technique [0002] Ring network cabinet is a group of high-voltage switchgear installed in steel metal cabinets or electrical equipment made of assembled spaced ring network power supply units. The advantages of improving power supply parameters and performance and power supply safety, etc., ring network refers to a ring-shaped distribution network, that is, the power supply trunk forms a closed ring, and the power supply supplies power to the ring trunk line, and from the trunk line, it is distributed all the way through the high-voltage switch. The advantage of this is that each distribution branch can take power from its left main line and its right main line. When the left main line fails, it continues to receive power from the right main line. Power is supplied, and when the right main fails, it conti...

AI Technical Summary

Problems solved by technology

[0002]Ring main unit is a set of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval type ring network power supply unit. Its core part is a load switch And fuses, which have the advantages of simple structure, small size, low price, can improve power supply parameters and performance, and power supply security. The power supply is distributed from the main line through the high-voltage switch one by one. The advantage of this is that each power distribution branch can get power from its left main line and its right main line. If the left main fails, it continues to receive power from the right main, and when the right main fails, it continues to receive power from the left main, so that although the main power supply is single, the From the point of view of each power distribution branch, it can get benefits similar to dual-circuit power supply, thereby improving the reliability of power supply. However, the existing ring main unit works for a long time in a hot area, and the internal electronic components are easily damaged. Damaged or even burned due to high temperature, the existing ring main unit generally uses natural heat dissipation or a single cooling fan for heat dissipation, which is far from enough in hotter areas, and the ring main unit needs to be used frequently during use. For inspection and maintenance, and the electronic components in the existing ring network cabinet are generally installed on the rear inner wall, so that the staff almost have to drill into the cabinet during inspection and maintenance, which is very inconvenient
