Compact substation is a compact complete set of power distribution device that combines high-voltage switchgear, distribution transformer, low-voltage switchgear, electric energy metering equipment and reactive power compensation device in one or several boxes according to a certain wiring scheme. To get more information about the substation, please read the following part, we are going to introduce the substation from some new aspects.
Where is the scope of use of Compact substation?
What is the operation process of the substation?
What aspects should be paid attention to in the operation of substation isolation switch?
Where is the scope of use of Compact substation?
The first type is mainly used in urban residential quarters and streets during peak electricity consumption periods. When we need to increase the voltage, we need to use our equipment Compact substation.
The second type is mainly used for temporary power supply. For example, in construction sites, in the case of existing buildings, we need to renovate electrical equipment. Compact substation is often used in field operations, such as construction sites, docks, airports, and so on.
What is the operation process of the substation?
The type of box type substation can be divided into ordinary type and compact type Ordinary box type substation includes zbw type and XWB type, while compact box type substation includes zb1-336 type and Ge box type substation The 10kV power distribution device of box type substation does not use circuit breaker. The commonly used ones are fn5-10 or fn7-10 load switch plus fuse and ring network power supply device, and are connected to the high-voltage end of the transformer from the adjacent overhead line The incoming line can be cable or overhead insulated line, which can be selected arbitrarily according to the service environment and different purposes As a public box type substation, the low-voltage outgoing line of the box type substation depends on the transformer capacity, generally no more than 4 circuits, no more than 6 circuits at most, or one circuit of total outgoing line can be used for branch power supply to the adjacent distribution room As a box type substation for independent users, primary circuit power supply can be adopted.
What aspects should be paid attention to in the operation of substation isolation switch?
- Observe whether the porcelain bottle supported by the substationisolation switch is clean, complete, free from cracks, breakage, and discharge traces.
- Observe whether the mechanical interlocking device is complete and reliable.
- Check that there should be no overheating, no discoloration, no oxidation, no breakage, etc. in the lead connections.
- When the isolating switch is stuck, do not use strong pull to avoid the isolating switch from damaging or damaging the grounding interlocking device.
With the development of technology, substations are constantly improving themselves. In the long time, substation will be a must in the industrial procuction. To meet these growing demands, Zhejiang Kunji Electric Co. has various Compact substations and they are all more effective, reliable, and consistent.
