Description
Technical field
The utility model relates to a kind of oil conservator of transformer, especially relates to a kind of capsule-type barrier film oil conservator.
Background technology
Power transformer is one of important electrical in the electric power system, if it has an accident, not only power department self loss is very large, but also brings very large impact can for the production of power consumer, life, and therefore, the reliability that improves it is very important.Oil conservator is as one of assembly of protection equipment for transformer, and Main Function is to store transformer oil and balance oil conservator internal pressure, makes simultaneously transformer oil and air insulated, prevents the transformer oil oxidation.And transformer oil mainly plays cooling and insulation maintenance when transformer moves, and when transformer oil was very few, the cooling recirculation system of transformer easily caused oil temperature too high with influenced, caused transformer to burn out.
And traditional capsule-type or diaphragm type storage oil cabinet all cause false oil level easily.
Such as capsule type oil storage cabinet, it is that inwall at oil conservator has increased a collapsible bag, and the bottom surface of collapsible bag floats on the oil conservator closely, and making between collapsible bag and the pasta does not have air, has completely cut off contacting of pasta and air.The variation of pasta is passed to the gear rotating mechanism by connecting rod again by placing the buoy strong point on the collapsible bag to move up and down in the oil conservator, and the oil level gauge pointer is rotated, and by the digit position that the oil level gauge pointer refers to, calculates the height of oil level.And oil level is when low, and the collapsible bag surface is fold easily, and during toward the oil conservator oiling, the buoy strong point just is positioned at the fold place of collapsible bag, and this will indicate the oil level to a mistake of pointer, be commonly called as " false oil level ".This " false oil level " will bring serious consequence to transformer, and be foregoing, and the accidents such as transformer burns out easily occur.Simultaneously, the sealing of diaphragm type or capsule type oil storage cabinet is unsatisfactory, air easily from around enter into transformer oil, cause in the transformer oil a part of oxygen of dissolving, airborne oxygen will impel transformer oil and the fiber that is immersed in the oil aging, affect the performance of transformer.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, a kind of good airproof performance is provided and can accurately shows the transformer capsule-type barrier film oil conservator of oil level.
To achieve these goals, the utility model is by the following technical solutions: a kind of transformer capsule-type barrier film oil conservator, comprise cabinet and the collapsible bag of being located at cabinet inside, the bottom of described cabinet is provided with a pouring orifice, and pouring orifice is connected with transformer by petroleum pipeline; Described cabinet is provided with a magnetic force oil meter, this magnetic force oil meter comprises table body, linkage and the buoy strong point, one end of this linkage is in transmission connection with the table body, the other end and the buoy strong point are connected; the buoy strong point places the upper surface of collapsible bag; the middle and lower part at described collapsible bag two ends and the inwall of cabinet are connected, and the bottom of collapsible bag and the bottom of cabinet are connected; The bottom of collapsible bag is provided with an oil fuel tube, and this oil fuel tube passes pouring orifice and is connected with petroleum pipeline; The sidewall of petroleum pipeline is provided with an oil inlet pipe; Described collapsible bag is provided with a steam vent; The top that is positioned at steam vent on the described cabinet is provided with a handle hole.
As preferably, described cabinet is provided with the dehydrating breather connecting leg, effectively removes moisture in the oil conservator.
As preferably, described magnetic force oil meter connects a controller, reports to the police when oil level is surpassed set point or is lower than set point.
As preferably, be connected by flange seal between described oil fuel tube and the petroleum pipeline.
As preferably, described oil inlet pipe is provided with a cubic valve.
The utility model makes collapsible bag become a Fuel Tanking Unit by transformer oil is injected collapsible bag.Before the oiling, by the vent valve on the handle hole operations platoon pore, drain a bag interior air first, carry out again oiling.During oiling, the upper surface of collapsible bag can fully expand because of the increase of oil mass, can not produce fold fully, and the displacement that the buoy strong point is measured is accurately oil level, has effectively avoided the generation of false oil level; And, airborne oxygen no longer with oil in gas exchange mutually, the content of dissolved oxygen descends gradually in the oil, until all run out of, thereby can reach the purpose that stops oily oxidation; Moreover, can also prevent that with the collapsible bag oil storage extraneous moisture, impurity etc. from along with transformer oil is invaded transformer inside, making transformer can keep certain degree of drying; When transformer oil varied with temperature, collapsible bag also can expand thereupon and compress, and had played the effect of breathing.
In sum, the utlity model has following advantage: the utility model is simple in structure, novel, and the accurately oil level of measuring transformer, and better tightness can effectively stop entering of oily oxidation and moisture, has guaranteed the normal operation of transformer.
