compact substation design

farady compact substation also known as the outdoor sets of substation, also known as modular substation, it was developed in the 1960s and 1970s in Europe and America and other Western countries launched a new transformer substation outdoor sets of equipment, because it is a combination flexible, easy to transport, migration, ease of installation, short construction period, low operating cost, pollution-free, maintenance-free advantages, by the world electricity workers seriously. Into the mid-1990s, the country began to appear simple box-type substation, and has been developing rapidly. electrical substation set up in two ways: one transformer exposed, another will press is installed in a closed compartment, farady 33kv substation using the second wiring, transformer installed in a closed compartment transformer.

Various types of power distribution equipment

Mother of the cabinet: When a system has two power line, and two spare each other, you need to master two power buses were Unicom, China Unicom two bus called the mother of the switchgear cabinet, pay attention: mother of the cabinet and the two line counters at the same time closing the general prohibition
Combined capacitance compensation cabinet: reactive power compensation, improve power quality, reduce losses, while providing data distribution operation. Transformer cabinet installed a 50kva power transformer, electric transformer that is supplied electric transformer substation. Liter cabinet: High-voltage switchgear with low voltage cabinet because different clearances that are greater than the high-pressure cabinet low voltage cabinet, in order to ensure the gap, so to add one such promotion cabinet (some lift cabinet is also fitted with isolation switch)Outgoing cabinet: power output from this cabinet, generally has a breaking, isolation and various protection functions (over-current, speed off, overvoltage, undervoltage, zero sequence, differential, stall, etc., can be configured according to the device to be protected ).
