Better to know to a 630 kva mini substation

A 630 kva mini substation is also called a 630 kva compact substation, which is an excellent solution to support electrical energy for manufacturing company, residential community, and central business district. Each of 630 mini substation is designed to fit electricity demand and working environment from terminal users.

For example, it needs a higher fire protection and corrosion protection in a chemical plant than a residential area. In this case, the substation shell will be made by galvanized sheet rather than composite materials. Meanwhile, factory electricity has larger demands on inductive load than residential electricity, such as electric motor, CNC production equipment, and product inspection equipment. The factory will need soft starter or frequency converter in their 630 kva mini substation. In additional, the industrial electricity needs more stable power to supply because of the heavy load units.

Conso Electrical Science and Technology Co., Ltd mainly produce gas insulated switchgear and air insulated switchgear, 10 kv to 35 kv distribution transformer and compact substation, and vacuum circuit breaker.

In Conso Electrical, each 630 kva mini substation is designed according to the SLD and technical requirement document from terminal users. Since 2006, Conso Electrical has collected 630 kva mini substation designing solutions from business cooperation with clients. The company will produce and supply each 630 kva mini substation with full respect.

What is a 630 kva mini substation?

The 630 kva mini substation is an electrical facility, which includes a 630 kva distribution transformer, and electrical panels. The electrical panels could have the function of receiving and feeding power, measuring and metering energy used, protecting and monitoring electricity. In addition, the 630 kva is the total capacity that the compact substation could supply.

To meet the demand of grid miniaturization construction, the substation is designed as a tighter dimension, which is convenient to install in densely populated areas, such as downtown, and CBD. Even though a 630 kva pad mounted transformer has a tighter designing than a 630 kva mini substation, the 630 kva pad mounted transformer is oil immersed mostly.

What is the voltage of a 630 kva mini substation?

The input and output voltage is alternative according to the local power grid. Generally, Conso Electrical could produce 10 kv to 35 kv 630 kva mini substation. In a 35/0.4 kv 630 kva compact substation, the gas insulated switchgear is suggested on the primary side as the dimension is close to a 10 kv KYN28-12 type switchgear. Ever more, the dimension of a KYN61-40.5 switchgear is 1400*2600*2800 (MM), which is inconvenient to suffer oversea shipment.

In addition, the container shell is also suggested to a 630 kva mini substation. Although the material costs is higher than regular materials, the costs can be saved from shipping. It is because the dimension of a 630 kva mini substation is about 2300*4500*2500 (MM), which needs a frame container to load.

How much power is in a 630 kva mini substation?

Obviously, It could supply 630 kva total power in a 630 kva mini substation. However, some part of power, which is called reactive power, is used to control the quality of electricity. Normally, more than 90% of total power will be used as energy conversion. Thus, it is about 567 kW power could a 630 kva mini substation actually supply.

In addition, it will hurt the designing service life that a 630 kva mini substation is full load all the time. 50% to 80% load rate is a reasonable range.

How much kvar needs in a 630 kva mini substation?

The reactive power compensation unit could increase the power rate for AC circuit in the range of 0.9 to 1.0. Meanwhile, it could reduce electricity consumption and maintain voltage level. Inductive loads, such as electricity motor, will increase the occupation of reactive power in the AC circuit.

Generally, it suggests 30% of transformer rated capacity in a 630 kva mini substation that is an appropriate rate to apply in the reactive power compensation unit.

How many secondary outgoing circuit needs in a 630 kva mini substation?

The number of output circuit depends on the working environment from terminal user side. Probably, the rate current of 630 A 400 A 225 A and 125 A molded case circuit breaker will be installed in the control panel. Meanwhile, it needs about 3 ways of spare circuits in the 630 kva mini substation. In this case, it probably will install 6 to 8 ways of output circuit on the secondary voltage side of a 630 kva mini substation.

In additional, it might need to take TMY-3*(80*6), TMY-1*(50*5), and TMY-1*(40*4) as main busbar, neutral busbar, and PE busbar in a 630 kva mini substation, respectively.

What is the price of a 630 kva compact substation?

Take a YB27-10/0.4-S11-630 compact substation as an example,The manufacturing costs is about $13100 to $25000. the following factors impact costs significantly: shell material, branded components, and transformer material costs.
