Replacing method of silica gel applicable to transformer respirator

Abstract

The invention discloses a method for replacing silica gel suitable for a transformer respirator, which includes the following steps: A: Use a wrench to loosen the screws of the respirator and the breathing catheter, remove the respirator, wrap a dry towel around the breathing catheter, and then wrap the plastic Wrap the dry towel with the film, and fix the plastic film, dry towel, and breathing tube with rubber bands; B: Remove the oil cup and tie rod bolts at the bottom of the respirator in sequence with a screw pen and a wrench, then wet the bottom of the respirator with water, and then Use a blower to dry the connection between the bottom of the respirator and the flange, and rotate and remove the flange while blowing; C: Then remove the long screw rod and fixing flange of the respirator, open the silicone tank of the respirator, and put the inner silicone Take it out, apply alcohol on the inner wall of the silicone tank, and dry the inner wall of the silicone tank with a hair dryer; D: Put new silicone into the silicone tank, and put the fixed flange, long screw, flange, tie rod bolt, oil cup, screw and Silicone tank installed.

Description

technical field [0001] The invention relates to the technical field of transformer maintenance, in particular to a method for replacing silica gel suitable for transformer respirators. Background technique [0002] Glass jars, connecting pipes, oil seal cups, isolation nets, silica gel and transformer oil make up the respirator of the transformer. Silica gel is mainly contained in the glass tank of the respirator. When the oil temperature of the transformer drops, the volume of the oil tank shrinks, and some gas will be sucked in. The silica gel can dehumidify and absorb the gas sucked into the respirator. The transformer oil is contained in the oil seal cup, which can isolate the silica gel from the atmosphere, so that only the air entering the transformer oil conservator can pass through the silica gel, thereby prolonging the service life of the silica gel. When dry, the silica gel is mostly blue, and when it absorbs moisture, the silica gel gradually turns pink. When th...
