Description
Technical field
The utility model relates to transformer equipment auxiliary implement, is specifically related to a kind of transformer self-healing dehydrating breather.
Background technology
Moisture absorber of transformer is a kind of glass container that the humectant material such as discolour silica gel are housed, and plays impurity and moisture in filtered air, to keep the clean and dielectric strength of transformer oil, prevents a kind of device of transformer insulated oil degradation.
Traditional dehydrating breather uses disposable allochroic silica gel to carry out moisture absorption to the gas of turnover installation for transformer, needs artificially to change silica gel to keep the moisture absorbing of dehydrating breather after silica gel water absorption is saturated.While changing silica gel, dehydrating breather need be taken off from transformer, pour out old silica gel, pack new silica gel into.Changing frequently silica gel not only wastes time and energy, and has increased the operating cost of transformer, but also can because of dismounting dehydrating breather, affect the continuity of air cleaning, then affects transformer operational reliability; If the silica gel after replacing is dealt with improperly, also can cause environmental pollution.
Utility model content
The purpose of this utility model has been to provide a kind of for the self-healing dehydrating breather on transformer, it has solved the problem that existing dehydrating breather needs often to change hygroscopic agent, employing is heated and is removed moisture the hygroscopic agent making moist, and simple in structure, it is time saving and energy saving to operate, can improve transformer operational reliability can be for the transformer economy of different capacitance grade, carry out moisture absorption dehumidifying effectively, safely, has feature applied widely.
The technical scheme that realizes the utility model object is:
A kind of transformer self-healing dehydrating breather, comprise glass infuser, glass infuser upper end arranges upper flange and is connected with transformer flange-interface, glass infuser lower end arranges lower flange and is connected with air inlet cavity with water outlet, unlike the prior art: in glass infuser, be provided with filtering net cylinder, the inwall of filtering net cylinder and glass infuser has certain gap, the center of filtering net cylinder is provided with and connects on glass infuser, the filtering net cylinder main shaft of lower flange, on filtering net cylinder main shaft, be fixed with the carbon fiber heating net of annular array, in carbon fiber heating net, be provided with temperature sensor, during use, in filtering net cylinder, fill hygroscopic agent, the bottom of glass infuser is fixed with LOAD CELLS, in water outlet and air inlet cavity, be provided with heating core, glass infuser is provided with controller outward and is connected with upper flange, is provided with the embedded microprocessor controller unit that adopts technical grade in controller, described carbon fiber heating net, temperature sensor, LOAD CELLS and heating core are connected respectively wire and are connected with controller.
Between the upper and lower flange of described glass infuser, be also provided with screw pull bar and be fixedly connected with, screw pull bar is located at the gap of glass infuser and filtering net cylinder.
Gap at glass infuser and filtering net cylinder is also provided with wire-passing tube, and wire is connected with controller through wire-passing tube.
In described water outlet and air inlet cavity, be filled with ceramic particle, increased the length that air enters, can the airborne dust of filtering, replace the lubricating cup of traditional dehydrating breather.In water outlet and air inlet cavity, be provided with heating core, by controller, automatically controlled, object is to solve that severe cold area condensed water freezes and the problem that causes spiracle to be stopped up.
Described glass infuser adopts quartz material, can bear the high temperature of 1000 ℃, has extraordinary cold-and-heat resistent cataclysm ability.
Described controller is prior art, adopts the embedded microprocessor of technical grade, applies online heating, drying reduction technique, and controller adopts in the course of the work weighs and two kinds of modes that function combines of timing.
When the utility model is installed, by upper flange and transformer, join, gas circuit during transformer expiration is identical when air-breathing.In the process of breathing at transformer, LOAD CELLS is measured the weight of hygroscopic agent in glass infuser in real time, and measurement result is reached on controller, when the weight of hygroscopic agent surpasses set point, show that hygroscopic agent again can not absorb moisture, this Time Controller just can start the heating of carbon fiber heating net.From the water vapour of hygroscopic agent evaporation, from water outlet and air inlet cavity, discharge, by the operation conditions of temperature sensor monitors carbon fiber heating net, thereby realize hygroscopic agent circular regeneration, use simultaneously, reach the object of self-healing.
Compared with the existing technology, tool has the following advantages the utility model:
1. adopt the carbon fiber heating net of annular array, can to hygroscopic agent, heat equably from top to bottom;
2. set LOAD CELLS, can Real-Time Monitoring glass infuser in the weight of hygroscopic agent, without artificial on-the-spot tour, time saving and energy saving, avoid the adverse effect because artificially error in judgement is brought power transformer;
When hygroscopic agent is saturated without artificial replacing, as long as control carbon fiber heating net on-line heating, can make hygroscopic agent regeneration, solved the problem that wastes time and energy existing because of frequent replacing hygroscopic agent, reduced the operating cost of transformer, avoid complete machine dismounting, thereby guaranteed the continuity of air cleaning, improved transformer operational reliability;
4. avoid producing too much discarded hygroscopic agent pollution on the environment;
5. the utility model is simple in structure, economical and practical, has feature applied widely, realizes the self-healing moisture-absorption characteristics of moisture absorber of transformer.
