Moisture absorbing device for transformer

Abstract

A moisture absorbing device for a transformer belongs to the technical field of moisture absorbing devices for transformers. The technical problem to be solved is to provide a moisture absorbing device for a transformer.The technical scheme adopted for solving the technical problem comprises the following steps: a moisture absorbing box body is included; a movable door is arranged on the front side of the moisture absorbing box body; the outer side wall of the moisture absorbing box body is connected with the movable door through an adjusting buckle; a transparent observation window is also arranged on the movable door. A plastic box is arranged inside the box body of the moisture absorbing box body, the surface of the plastic box is provided with a through hole, and the inside of the plastic box is also provided with a color-changing silica gel; the top of the moisture absorbing box body is provided with a first connecting hole, and the first connecting hole is connected with the flange through a connecting pipe. The bottom of the moisture absorbing box body is provided with a second connecting hole, an oil cup interface is arranged on the outside of the second connecting hole, and the bottom of the oil cup interface is connected with the oil cup. The moisture absorbing device of the invention is installed and applied in related devices in a substation.

Description

technical field [0001] The hygroscopic device for a transformer of the invention belongs to the technical field of transformer hygroscopic devices. Background technique [0002] Existing transformer dehumidifiers are mostly made of glass materials. The silica gel inside the dehumidifier needs to be replaced after absorbing moisture and discoloration. During the replacement process, the dehumidifier needs to be removed from the transformer. Due to reasons such as bolt corrosion and rubber pad adhesion, the replacement process Complicated, it is also easy to cause the body of the dehydrating absorber to be broken and damaged. The sealing effect of the replaced dehydrating absorber may become worse. One replacement requires two skilled workers to cooperate with wrenches, pliers and other tools to operate, and it takes an average of 35 minutes to complete the operation.

[0002] Existing transformer dehumidifiers are mostly made of glass materials. The silica gel inside the dehumidifier needs to be replaced after absorbing moisture and discoloration. During the replacement process, the dehumidifier needs to be removed from the transformer. Due to reasons such as bolt corrosion and rubber pad adhesion, the replacement process Complicated, it is also easy to cause the body of the dehydrating absorber to be broken and damaged. The sealing effect of the replaced dehydrating absorber may become worse. One replacement requires two skilled workers to cooperate with wrenches, pliers and other tools to operate, and it takes an average of 35 minutes to complete the operation. Among them, replacing the silica gel of the dehumidifier is a regular maintenance work, the frequency of replacement is high, and the maintenance workload is heavy

[0003] Due to the long replacement operation time, the moisture in the air may directly enter the transformer oil conservator during the replacement process, and the replaced new silica gel will also be exposed to the moisture for a long time, which will affect the safe operation of the transformer and reduce the service life of the new silica gel; Conditional maintenance regulations Silicone needs to be replaced when two-thirds of the color changes, but according to actual work statistics, it is basically replaced when one-third of the color changes

[0004] On the other hand, during the replacement process, the discolored and undiscolored silica gel poured out are mixed together, and some of the silica gel at the bottom of the dehumidifier is also contaminated with oil and dust, so all of them need to be replaced, and the contaminated old silica gel is dried again It is very difficult to process and utilize, so it can only be thrown away, causing waste of materials and environmental pollution
