In December 2020, ruidaneng replaced respirators for 750kV substation in Bayingol Mongolian Autonomous Prefecture, Xinjiang. The installation engineers of Ruidaneng did not fear the severe cold and quickly replaced the new respirator. Minimize the impact of respirator replacement on the substation. Relevant personnel were trained.
Since the silica gel filter element of the traditional moisture absorber shall be replaced in time after water absorption is saturated, otherwise the moisture absorber will be blocked, which will endanger the safe operation of the transformer. Therefore, the maintenance team shall regularly check whether the silica gel is saturated and discolored and replace it if necessary. This leads to a large maintenance workload. The new maintenance free dehumidifier can sense the water absorption saturation of the filter element through the sensor and start the heating function to ensure that the filter element is in a good water absorption state for a long time. Reduce maintenance workload.
