⑶ temperature display systems: embedded in the low voltage winding through the Pt100 temperature thermistor measured value taken directly to the display of each phase winding temperature (maximum three-phase inspection and display, and recorded its highest temperature) can be up to temperature to 4 ~ 20mA analog output, For transmission to remote (distance up to 1200m) computer protection mode IP20 protective shell is usually used to prevent the diameter greater than 12mm of solid foreign objects and rats, snakes, cats, birds and other small animals from entering, cause a short power outages and other serious failure to provide a safe barrier for the live part. If the transformer shall be installed outdoors, you can choose IP23 protective shell, in addition to the IP20 protection, but also to prevent the vertical angle of 60 ° or less of water droplets into. But IP23 enclosure transformer cooling capacity will drop, should pay attention to the selection of reduced operating capacity.
