Difference Between The Air Switchgear And RMU

After a long period of production and research and development, the power supply equipment has gradually formed a ring network cabinet, which can ensure the safety and reliability of power supply. Among them, the gas-insulated ring main unit has received a lot of praise and vigorous promotion in the market as soon as it was inquired into the market. So what is the difference between this air switchgear and the ordinary rmu?

1. The main difference between the two types of RMU

The main body of the air switchgear is quite different from the ordinary ring network cabinet. The inflatable ring network cabinet is mainly an indoor AC high-voltage gas-insulated and metal-enclosed switchgear. Combination of sulfur fluoride compartments; while the main ring main unit is a group of power transmission and distribution equipment installed in a metal or non-metal insulating cabinet.

2. Differences in the characteristics of the two types of ring network cabinets

The characteristics of moderately priced air switchgear and ordinary ring network cabinets are also very different. The inflatable ring network cabinets use sensing technology and have high-tech protection relays and assembly solutions, which can adapt to more scenarios. However, the common ring network cabinet uses load switches and fuses, and the shape and structure are very simple.

3. Differences between the two types of ring network cabinets in usage scenarios

Inflatable RMUs with guaranteed quality are generally suitable for small secondary substations, box-type substations, large shopping malls, industrial and mining enterprises, etc. in power systems, and also have very good applications in airports or railways and other scenarios; The ordinary ring network cabinet is mainly used in urban residential quarters, high-rise buildings and various factories and enterprises.

From the above content, the difference between the air switchgear and the ordinary ring network cabinet can be clearly distinguished. The two have great differences in overall structure and performance, and there are also obvious differences in usage scenarios. Therefore, it can be considered that if the usage scenario has very high requirements for power supply, this inflatable ring network cabinet can be used; if there is no such high requirement for power supply requirements, then ordinary ring network cabinets can be used.
