Box type transformer (usually referred to as the "box") will be designed in the box shell in the traditional transformer has the advantages of small volume, light weight, low noise, low loss, high reliability, widely used in residential, commercial center, light station, airports, factories and mines, enterprises, hospitals, schools and other places.
Box type transformer is not only transformer, it is equivalent to a small substation, belonging to the distribution station, to provide power to users directly. Including high pressure chamber, a transformer chamber, the low pressure chamber. The high-pressure chamber is the power supply side, is generally 35 thousand or 10 thousand volts into the line, including high voltage bus (High voltage busbar), circuit breaker or fuse, voltage transformer, lightning arrester, transformer room transformer is the main equipment box, low voltage room inside low voltage busbar (Low voltage busbar), the measurement device of low-voltage circuit breaker, arrester, etc., from the low voltage busbar The overhead line is powered to the user.
Protection box type transformer is specially transformer protection, is set in the development of protection, monitoring, control, communication and other functions in one of the high-tech power automation products, constitute the ideal electric appliance unit intelligent box type transformer. The product is built by a more than 20 standard procedures for the protection of the protection of Library analog data and a strong and complete equipment of voltage and current acquisition function (current measurement via CT protection).
We are Box type transformer manufacturer and exporter in China,proving good quality products.
