When it comes to pre-assembled substations it is in fact what we call a box-type substation, which is only not a new name for it. The equipment is a high voltage switch and distribution transformer. In use are prefabricated factory indoor and outdoor compact power distribution equipment lined up in accordance with certain wiring schemes.
Generally it is installed in some relatively moisture-proof, rust-proof, dust-proof, rodent-proof, movable steel structure box, to be mounted substation application sites, in fact it is particularly suitable for urban network construction and transformation, is following the rise of a new substation after the civil substation. Places like mines, factories and enterprises, oil and gas fields and wind power stations that we know are in need of it, and you often see it as well.
Since the pre-installed substation has really replaced the previous kind of civil power distribution room, distribution station, as a new type of power distribution device has been recognized by many people. With the rapid development of our country's social economy, our electricity business and the process of urban development are also proceeding at a rapid pace, in which case the overall electrical load is increasing and the supply of land resources in the city is also relatively tight.
This has led to an increasing number of problems with civil engineering substations, which have been solved by pre-installed substations. This is because it offers new ideas, both in terms of the design and construction of the entire substation, and its workload has been greatly improved. According to the current situation, the development trend of this equipment will always be very good.
High voltage / low voltage pre-installed substations, according to the design and user requirements, pre-installed substations are generally divided into three rooms: high voltage room, transformer room and low voltage room. High voltage room: can be designed and installed with high voltage inlet cabinets, high voltage metering cabinets, high voltage PT cabinets and high voltage outlet cabinets. Transformer room: dry type transformers and oil type transformers can be installed. Low-voltage room: low-voltage inlet cabinets, reactive power compensation cabinets, feeder cabinets, double power switching cabinets, contact cabinets, etc. can be designed and installed.
The high voltage cabinets all meet the national standard five-proof requirements. The high voltage room is equipped with functions such as opening the door and lighting up. The transformer room has the functions of automatically starting the fan to dissipate heat when the temperature is too high, opening the outer door to light up, and opening the inner network door to trip the corresponding transformer high-voltage side circuit breaker. The low-voltage room is equipped with functions such as opening the door and lighting up, automatic switching of each feeder and power supply hand and reactive power compensation as required by the design.
The high-voltage/low-voltage pre-assembled substation has all the internal wiring required for the high-voltage room, transformer room and low-voltage room completed and qualified before leaving the factory. The user only needs to install the HV/LV pre-assembled substation in the corresponding installation position, connect the protective earthing line, connect the HV inlet and outlet lines, LV inlet and outlet circuits, set the user's protection settings and complete the overall test before powering up and running. The high and low voltage rooms can be designed and installed with air conditioning according to demand.
High-voltage/low-voltage pre-installed substation, reduce space, small size, easy to install, low cost, easy to replace the use of location.
