Description
Technical field
The utility model relates to a kind of respirator for transformer, belong to transformer technology field.
Background technique
Transformer is very important electrical equipment in electric system, in operation with the variation of temperature and load, is become
Oil level will be raised and lowered inside depressor, safe accessory of the oil conservater as transformer, using full-closed structure, in pasta
So that inside transformer is kept normal pressure state when being raised and lowered, to prevent transformer oil in oil conservater or capsule from sealing top
Air is directly contacted with atmosphere, is slowed down the degradation speed of transformer oil and is prevented pollution of the air to insulating oil, in oil conservater
Air is connected by respirator with outside air, if be not thorough to the filter moisture in air, easily causes conservator capsule
The aggregation of interior moisture, once breakage occurs in capsule will cause serious influence to transformer, conventional transformer respirator is to pass through
Whether the discoloration of routine observation silica gel reaches regulatory requirements discoloration to 2/3 to judge whether silica gel fails to be replaced, and deposits
In following problems:
1) discoloration silica gel contains toxic chemicals, and fractional unit does not have in Unified Set discarded discoloration silica gel at present
, there is very big environmental pollution hidden danger in reason.
2) oil sealing cup prevents dust from entering by bottom oil collection box, but need to periodically be cleaned, and will block up as cleaning is not thorough
Respiration channel is filled in, transformer station high-voltage side bus failure is caused；Silica gel does not carry out periodic replacement, and to may cause silica gel water suction supersaturation final broken
It splits, the powder of rupture, which agrees that respirator hole can be will lead to be blocked, to be clogged, and there are security risks；
3) silica gel replacement quality is affected by personnel's technical ability, and what silica gel replaced criterion support is artificially to judge, judges to mark
Quasi- related with operation maintenance personnel technical ability, silica gel replaces same process complexity, need to be in the case where the good air humidity of weather conditions is small
It carries out, determines that the size, model and last time of the respirator replace the silica gel time before replacing, calculate time interval, it is preliminary to judge
Dampness reason；Be ready to before work discoloration silica gel, rubber sealing ring pad, transformer oil, with model respirator and construction tool；Work
It holds work ticket before work successfully, deactivates Transformer Heavy Gas protection in short-term to traffic department's application, prevent (the oil of air-flow in replacement process
Stream) it springs up and causes grave gas protection act；Oil sealing cup is cleaned and changed oil, all sealing rings by exertin require more
It changes.The whole series replacement quality and operation maintenance personnel operative skill are closely related, and existing respirator is mostly detachable organic glass volume
The silica gel tank of silica gel tank and non-dismounting type, wherein the respirator of detachable needs operations staff to more during replacing silica gel
Change of current journey and the requirement of the tense-lax degree of screw are relatively high, otherwise easily cause the damage of organic glass, and entire replacement process expends
Time is long, and respirator part junction poor sealing is also resulted in when the number of replacement is more, makes moisture without silica gel
Filtering, is directly entered in installation for transformer, may cause transformer oil dampness；Although the respirator of non-dismounting type is avoided that disassembly
The unfavorable factor of formula respirator, but during replacing silica gel, since the tank mouth for pouring into silica gel is smaller, silica gel is caused to spill
It falls, pollutes environment.
4) as the demand of electric power increases year by year, the transformer of more enlarged will come into operation, larger at the same time
Transformer just will use more large-scale respirator (weight of desiccant and the oil mass of transformer for be positively correlated).If using more
Bulky respirator, replacement also will be bothered more；If respirator size do not change so also will at double increase replacement
The number of silica gel；
5) since the installation of some transformers silica gel tank is excessively high, replacement silica gel needs to carry out power failure maintenance, will also increase and stop
Electric number finally can also reduce the service life of transformer.
