Why do we need substation?

The substation is suitable for mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution rooms and power distribution stations, and becomes a new type of complete set of power distribution devices.

What are the substations of the high-voltage power distribution device structure?

There are two types of cable entry methods: terminal type and ring network type; from the perspective of cable entry, it can be divided into: overhead cable entry from the top of the box (this method is often used in traditional box changes) and the use of high-voltage cable trenches. Underground access and exit, this is a more common method used in modern design.

There are many SF6 series load switches that use SF6 gas as the arc extinguishing medium, and their cost is higher than that of the FN-10 series high-voltage load switches. This kind of switch structure has fuse, no fuse, grounding switch, etc., but it is generally equipped with a live display; the operating mechanism is generally manual, and there are also electric operations. With a fuse, when the circuit has a short-circuit fault, it can automatically cut off the switch to protect the circuit, transformers, switches and other equipment.

There are also vacuum switches that use vacuum as the arc extinguishing medium. This type of switch can be used alone or with a fuse, and can also be used in series with the SF6 series load switch, but this will increase the cost, if the user has no special This is not required to be used.

What are the advantages of Compact substation?

Due to the selection of advanced equipment, especially the operation of oil-free equipment, compact substation fundamentally solves the problem of equipment leakage in conventional substations. Substations can be overhauled under condition, reducing maintenance workload and saving operation and maintenance costs each year.

What are the advantages of using Compact substation?

Compact substation is a kind of outdoor power supply equipment: Compact substation includes high-voltage incoming and outgoing lines, metering devices, transformers, low-voltage incoming lines, and low-voltage power distribution outgoing lines.

Advantage:

(1) It covers a small area and is suitable for installation in general urban load-intensive areas, rural areas, residential quarters, parks, etc. It is conducive to high-voltage extension, reduces the power supply radius of low-voltage lines, and reduces line losses.

(2) Reduce the basic cost of civil construction; it can produce in factory, shorten the on-site construction cycle, with less investment, and obvious results.

(3) Small size, light weight, easy to install and move.

After knowing so much about it, do you have a deeper understanding of Compact substations? Compact substation is very common in our daily life. Zhejiang Zhegui Electric Co. has been established for over ten years. As the most competitive manufacturer in China, they will devote their selves to producing the most competitive products for their clients.
