Description
Technical field
The present invention relates to transformer equipment field, in particular to a kind of Maintenance-free respirator of for transformer.
Background technique
Transformer is very important electrical equipment in electric system, if the dehydrating breather that oil conservater is connected is in air
Filter moisture is not thorough, and easily causes the accumulation of oil conservater capsule moisture, can be occurred when permeability occurs for oil conservater capsule serious
Equipment fault.Transformer be determine electric system can safe power supply an important factor for one of；And transformer breather is to determine
Determine the critical component of transformer performance, the superiority and inferiority of performance will directly influence the technical performance of transformer.Since transformer exists
Temperature can change at any time in operation, and the oil level of inside transformer is caused to be raised and lowered.And oil conservater is that semiclosed oil conservater is (existing
Transformer mostly uses totally-enclosed oil conservater), in this way since being raised and lowered for pasta can just make inside transformer keep normal pressure
State, (can be understood as breathing) therefore, in order to slow down the degradation speed of transformer oil (i.e. insulating oil) and prevent air to exhausted
The pollution of edge oil installs respirator additional in the exhalation passages of oil.Respirator is also silica gel tank, and transformer breathing passes through silica gel, then
By the oil filtering in the lubricating cup of respirator bottom, the cleaning and drying of air can be ensured substantially.
Since transformer breather is constantly in work, inevitably silica gel moisture absorption is saturated under long-time service
Phenomenon or silica gel failure, in the process of running, have water to enter transformer body, it is possible to and it will lead to transformer oil and be contaminated,
Oil it is rotten etc..It will lead to equipment operation failure when serious.Therefore, replacement in time is carried out to the silica gel of performance deterioration to be conducive to become
Depressor safe operation, guarantees power supply reliability.
For transformer, replacement dehydrating breather silica gel is a regular maintenance work, will be to dry every certain time
Drying prescription is estimated, and often to replace the desiccant of failure, and the cost that these work are spent is very considerable, and right
If the waste after replacement is dealt with improperly, environmental pollution can be further resulted in.
Corresponding research has also been made both at home and abroad to this, realizes and restores purpose free of replacement online, but the equipment done is deposited
Implementing that vapor can be generated in on-line heating reduction process in maintenance-free moisture absorber, is showing that automatic rising, vapor exclude
It is insufficient and the problem of suck vapor in transformer air-breathing；Meanwhile the existing breath device later period is with changing moisture absorption silica gel
It is cumbersome when grain.
In this regard, urgently develop a kind of strong applicability, it is economical and practical prevent vapor from rising in reduction process, water steams
Gas excludes the transformer maintenance-free moisture absorber device that the requirement of hot steam is sucked in insufficient or transformer breathing process.
