Solid insulated RMUs are more compact and environmentally safer. They are built as logical choices for consumers using medium voltage distribution systems. So if you want to provide power for up to 24kV substations, solid insulated ring main units will be probably a good option.
The substation is one of the terminal for ring main unit, there are two incoming power lines enter into ring main unit synchronous, one line for supplying user, another line for standby, it make the power supply net into ring circuit to ensure the power supply reliability.
The role of the ring main unit is to improve the reliability of power supply. It is mainly used in AC 11kV/33kV power distribution systems such as industrial and mining, residential, port and high-rise buildings. Because of the small load capacity, the high-voltage circuit is usually controlled by load switch or vacuum contactor. You see:
A ring main unit construction is made up of four parts. The switching room consists of several functional circuits. It includes load switches and ground switches. These are sealed in the busbar and metal housing between them. Three cold welds the shell rolled steel plates. Every functional loop is composed of a ground switch and a load switch.
The ring main unit circuit phase sequence shall be correct. The main grounding sign must be clearly and tightly as well. The ring main unit specification of the components shall follow to the requirements of the specifications of the rmu unit manufacturer.
The ring main unit specification of the components shall follow to the requirements of the specifications of the rmu unit manufacturer. The number shall follow to the electrical wiring drawings; the positions shall be organized according to the order of the upper, lower, left and right of the components.
