The Working Principle Of Box Type Substation

Aug 24, 2017


Box type substation (referred to as box change) is a kind of high voltage switch equipment distribution transformer, low voltage switch equipment, energy metering equipment and reactive power compensation device integrated automation system, communication, telecontrol, Box Type Transformer Substation metering, capacitance compensation and DC power supply and other electrical units Combined into one or several boxes within the compact sets of power distribution devices. It is suitable for use in rated voltage 10 / 0.4KV3 phase switching systems, Box Type Transformer Substation as a route and for the distribution of electrical energy.

Box-type substation works:

Mainly by the multi-loop high voltage switch system, armored bus, installed in a moisture, rust, dust, rodent, fire, security, heat insulation, full block, can move the steel structure of the box, full block operation. Box-type substation shell to take steel or alloy plate, with double top cover, good insulation. Box Type Transformer Substation Shell and skeleton all through the anti-corrosion treatment, with a long time to make some of the premise of outdoor (complete sets of equipment). Shape and color can be coordinated with the environment. Box Type Transformer Substation Installation is convenient, in the box-type substation under the foundation of the cable room, and in the low-pressure room with holes into the cable room to work.

From the volume point of view, the European-style box for the internal installation of conventional switchgear and transformers, the product is larger. American box change due to take a smaller body size (meter box). Box to high pressure side to take the load switch plus current limiting fuse maintenance. When the 1-phase fuse is blown, Box Type Transformer Substation the load switch 3 is opened at the same time with the striker of the fuse to prevent the phase loss operation. The request load switch has the ability to cut the transfer current. Low-voltage side to take the load switch plus current limiting fuse maintenance, the US box to change the high side of the fuse to maintain, Box Type Transformer Substation and the load switch only switching from switching and cutting off the high-voltage load current function, the capacity is small. When the high side of the side of a fuse fuse, low voltage side of the voltage drop, molded case automatic air switch undervoltage maintenance or over-current maintenance will work, low-voltage operation will not produce.

From the product cost, European-style box into the high cost. Box Type Transformer Substation From the product price reduction space, the US box also has a larger price reduction space, the US box can change the high-pressure parts from the transformer tank moved to the tank, the use of high-pressure room space.

Box-type substation shell to take steel or alloy plate, with double top cover, good insulation. Shell and skeleton all through the anti-corrosion treatment, with a long time to make some of the premise of outdoor (complete sets of equipment). Shape and color can be coordinated with the environment. Box Type Transformer Substation Installation is convenient, in the box-type substation under the foundation with a cable room, Box Type Transformer Substation and in the low-pressure room with human holes can enter the cable room to work. From the volume point of view, the European-style box for the internal installation of conventional switchgear and transformers, the product is larger. American box change due to take a smaller body size (meter box). Box to high pressure side to take the load switch plus current limiting fuse maintenance.
