Description
Technical field
The utility model relates to the dehydrating breather of transformer oil storage, is specially a kind of maintenance-free moisture absorber.
Background technology
Moisture absorption silica gel is applied to the filtration of transformer oil storage upper vent hole as air humidity filtering material, the moisture in main filtering air and dust.Adopt discolour silica gel to judge whether hygroscopic material lost efficacy by eye-observation, the way in past is, find the silica gel variable color of 1/3, the silica gel that will again more renew, inefficacy silica gel can only do waste treatment.
MR company for the problems referred to above Germany have developed a kind of device by on-line heating mode automatic reduction inefficacy silica gel, called after maintenance-free moisture absorber, it adopts principle to be that the method that after using filtered through silica gel, air humidity detects judges whether silica gel lost efficacy, if humidity is excessive, think that silica gel lost efficacy, start heater and thermal dehydration is carried out to silica gel, with the object reaching silica gel recycling and turn waste into wealth.There is following Railway Project in the maintenance-free moisture absorber of MR company, 1, judging that silica gel lost efficacy by Humidity Detection is a kind of determination methods indirectly, exist and identify inaccurate problem, when if outside air humidity is little, even if its humidity is also very little after the filtered through silica gel lost efficacy, equipment thinks that silica gel is effective thus, a kind of mistake that Here it is.2, transformer oil storage air vent hole air inlet and to give vent to anger be real-time change along with expanding with heat and contract with cold of oil, and expanding with heat and contract with cold of oil is along with transformer load is in change, irregularly follows.This will also exist silica gel just when thermal dehydration wet-hot steam be inhaled into the possibility of transformer oil storage, threaten further the reliability service of transformer.3, the air inlet outlet gas part of maintenance-free moisture absorber have employed sintered metal mesh version, play the effect of filtered air dust, but breathing state cannot be observed, be configured with lubricating cup below former traditional type dehydrating breather, have bubble when expiration and air-breathing and occur, transformer user can observe this phenomenon, be beneficial to and judge that whether oil conservator air vent hole is unimpeded, because once air vent hole blocking, Buchholz relay malfunction can be caused, and then there is transformer power failure phenomenon.
For solving the two problems that MR maintenance-free moisture absorber exists, COMEN company of Italy also have developed a kind of weighing principle that adopts and judges the double hose maintenance-free moisture absorber whether silica gel lost efficacy, COMEN company has given up and has identified by Humidity Detection the method whether silica gel lost efficacy, the substitute is the principle that after using silica gel moisture absorption, weight increases, whether moisture absorption is saturated to use LOAD CELLS to distinguish silica gel, opens heater further and carries out dehydration regeneration to it.In order to avoid the wet-hot steam in heating process is inhaled into transformer, what they adopted is the double pipe structure of the using and the reserved, by electromagnetically operated valve automatic switching mode, guarantees that the air be inhaled into is dry, to reach really non-maintaining object.Statistical analysis after user uses, also there is Railway Project in the maintenance-free moisture absorber of COMEN company, 1, the certainty of measurement of LOAD CELLS is limited to ambient temperature and comes from self vibrations when transformer runs, weight change after silica gel moisture absorption is micro-grade, and silica gel judges whether that by weighing the saturated principle of moisture absorption is only limitted to laboratory environment.2, when the maintenance-free moisture absorber of twin-tube type structure applies to capacity larger transformer, volume is too huge, is unfavorable for design and installation.3, remain breathing state cannot observe.
