A silica gel drying device for transformer maintenance-free moisture absorber

Abstract

Disclosed in the present invention is a silica gel drying apparatus for a no-maintenance dehumidifier of a transformer, comprising a silica gel tank body and a device body. A dividing panel is provided horizontally crossing an interior central portion of the device body, the dividing panel splitting the interior portion of the device body into a material storage compartment and a drying chamber. A bottom portion of the side of the material storage compartment near to the silica gel tank body is connected to the silica gel tank body at a material drop port thereof by means of a material output pipe one. A hollowed-out panel is provided horizontally crossing an interior lower portion of the drying chamber, and the side of the hollowed-out panel near to the silica gel tank body is in communicated connection with the silica gel tank body by means of a material inlet channel. A heating panel is provided blow the hollowed-out panel, a plurality of fan heaters are mounted below the heating panel and in an interior lower portion of the drying chamber, and an agitation apparatus is provided at a central position above the hollowed-out panel. The agitation apparatus comprises a fixed panel two, and fixed panel two is fixed at an interior upper portion of the drying chamber. Drying uniformity is thus increased, the use effect is improved, and the transformer is prevented from being impacted.

[0002] The transformer is a very important electrical device in the power system. If the moisture absorber connected to the oil conservator does not filter out the moisture in the air thoroughly, it will easily cause the accumulation of moisture in the capsule of the oil conservator. When oil leakage occurs in the capsule of the oil conservator, it will serious equipment failure

The transformer is one of the important factors that determine whether the power system can safely supply power; the transformer respirator is a key component that determines the performance of the transformer, and its performance will directly affect the technical performance of the transformer. Since the transformer respirator is always in work, Under long-term use, there will inevitably be moisture saturation of silica gel or silica gel failure. During operation, water enters the transformer body, which may cause transformer oil to be polluted, oil to deteriorate, etc., and in severe cases, it will cause equipment operation failure. Therefore , timely replacement of degraded silica gel is conducive to the safe operation of the transformer and ensures the reliability of power supply

[0003] At present, for transformers, replacing the silica gel of the moisture absorber is a regular maintenance work. The desiccant must be visually inspected at regular intervals, and the failed desiccant must be replaced frequently. The cost of these tasks is considerable. , and if the waste after replacement is not handled properly, it will further cause environmental pollution, and most of the existing ones are directly carried out in the silica gel tank, and the water vapor existing in the drying and heating process of the silica gel will enter the inside of the transformer, bringing the transformer Hidden dangers, according to the drying device described in the Chinese authorized patent CN206271512U, the silica gel desiccant is replaced by connecting the drying equipment on the outside, but when the recovered silica gel desiccant is dried, the silica gel desiccant accumulated inside The phenomenon of uneven drying makes some silica gel desiccants still have moisture, and when these desiccants are transported into the silica gel tank for operation, it will still bring hidden dangers to the transformer
