Problems solved by technology

A longer replacement time will bring more air into the transformer oil, affecting the insulation performance of the transformer oil
The existing equipment results in a long replacement time of silica gel, and the air that has not been filtered by the silica gel of the dehumidifier directly enters the body of the main transformer, thereby causing the silica gel to be damp and discolored. This is also a technical problem that needs to be solved in the development of a new dehumidifier device.

Embodiment Construction

[0010] like figure 1 As shown, a quickly replaceable oil conservator moisture absorber device includes a breathing tube 2 connected to the oil conservator 1, and the breathing tube 2 is connected to the moisture absorber 61 through a flange 3 and a valve 41 in sequence. A second channel communicating with the breathing tube 2 is provided between the flange 3 and the valve 41 , the valve 41 is movably connected to the moisture absorber 61 , and the second channel includes the valve 42 and the moisture absorber 62 connected to each other.

[0011] A clamping mechanism 51 is provided between the valve 41 and the moisture absorber 61 . A locking mechanism 52 is provided between the second channel valve 42 and the moisture absorber 62 . When the silica gel of the respirator 61 is damp and needs to be replaced, the spare small-sized moisture absorber 62 is installed on the interface of the clamping mechanism 52, the valve 42 is opened, and the moisture absorber B starts to run; the...

Abstract

The invention discloses a quick replaceable oil storage cabinet moisture absorber device, which comprises a breathing pipe which is connected with an oil storage cabinet, wherein the breathing pipe is connected with a moisture absorber through a flange and a valve in sequence; a second passage which is communicated with the breathing pipe is arranged between the flange and the valve; and the valve is movably connected with the moisture absorber. On the premise of guaranteeing breathing capacity of the moisture absorber, the oil storage cabinet is guaranteed to be kept in a normal breathing state when breather silica gel is moisturized, and heavy gas production is not stopped, so that safe and reliable running of a transformer is guaranteed; by opening and closing a vacuum valve, the moisture absorber is put in or withdrawn through a tool-free cutting ferrule quick joint; one person can manually convey to replace the breather silica gel; and thus, the device is convenient and fast, a large amount of time and maintenance cost are saved, and the working efficiency is effectively increased.

Description

technical field [0001] The invention relates to the technical field of moisture absorbers for oil storage tanks in transformers, in particular to a rapidly replaceable moisture absorber device for oil storage tanks. Background technique [0002] In the power system, the application of dehumidifiers for transformer oil conservator at home and abroad has not been paid attention to at present, and they are all straight-through working methods. These working methods do not take into account the environment in which equipment is used in various places, but simply use some screws and some rubber pads. The moisture absorber is connected to the transformer combination, so it is prone to problems. For example, the silica gel in the dehumidifier has a short lifespan and takes a long time to replace the silica gel, which affects the safety of the power supply. In the past, when replacing the silica gel, four screws on the dehumidifier had to be loosened, and only two people could compl...
