A Brief Introduction to Box Transformers

2023 07/25

As a complete set of power distribution equipment, box type transformer is an organic combination of transformer, high-voltage voltage control equipment and low-voltage voltage control equipment. The basic principle is to assemble the pressure starting system, armored cables, fully automatic substation system, DC system, and corresponding technical equipment in a specified sequence, and install all components into a specific waterproof, dustproof, and rodent proof fully sealed tempered box structure to form a specific transformer. Box type transformers have been widely used in power engineering construction.

A box transformer is not just a transformer, it is equivalent to a small substation, belonging to a distribution station that directly provides power to users. Including high-voltage room, transformer room, and low-voltage room; The high-voltage chamber is the power supply side, generally 35 kV or 10 kV incoming lines, including the high-voltage bus bar, vacuum circuit breaker or fuse, Voltage transformer, lightning arrester, etc. The transformer chamber is the main equipment of the box transformer, and the low-voltage chamber is equipped with low-voltage bus bar, low-voltage circuit breaker, metering device, lightning arrester, etc., which leads out lines from the low-voltage bus bar to supply power to users.
