Description
Technical field
The utility model relates to the oil conservator technical field, especially a kind of big capacity oil-filled transformer vacuum-pumping capsule-type oil conservator.
Background technology
The capsule-type oil conservator utilizes the contraction of oil resistant rubber air bag and expansion to replenish the breathing amount of transformer oil in running.Because the existence of capsule, transformer oil and isolate from outer air, thus effectively stop the external humidification air to enter in the transformer oil, reduce the insulating oil chance of breakdown, make insulating oil in long running time, maintain stronger electrical strength, reduced the oil in the running and be engaged in nursing.Simultaneously, such oil conservator can have the effect of indicating oil level and preventing glossy illumination aging owing to be furnished with charged signal contact pointer type fuel level indicator.
In existing big or middle capacity oil-immersed power transformer structural design, when adopting conventional capsule formula or diaphragm type storage oil cabinet structure, capsule or barrier film can cause breakage because of the negative pressure that is vacuumized generation, thereby can't satisfy with the transformer body and vacuumize the oiling requirement, and transformer can enter the portion of air band in the oil in the oiling process inevitably, owing to high voltage product insulation system complexity, easy formation chokes with resentment in device body built-in electrical insulation spare corner simultaneously.When transformer carried out the high voltage withstand voltage test, these bubbles, air gap easily produced discharge, punch-through under high electric field, and then had influence on the electrical strength of insulating oil and solid insulation, will have influence on the safe operation of transformer when serious.
The utility model content
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that solves above-mentioned existence, a kind of capsule-type oil conservator that can vacuumize with transformer body fuel tank is provided, can prevent that in vacuum capsule is because of being subjected to the negative pressure breakage, can remove simultaneously in the oil comparatively up hill and dale and the inner air content of device body, help improving complete machine insulation electric strength.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of capsule-type oil conservator that vacuumizes, has cabinet, be provided with capsule in the cabinet, cabinet one end is provided with pointer type fuel level indicator, cabinet is provided with oil inlet and outlet and sewage draining exit, be connected with capsule on the cabinet and breathe the dehydrating breather pipeline with dehydrating breather of usefulness, be connected with the ball valve pipeline that is used to vacuumize on the cabinet with vent valve, connect by connection balloon valve between dehydrating breather pipeline and the ball valve pipeline, oil conservator is connected on the transformer, can vacuumizes together oil conservator and body when opening connection balloon valve.
Further, simple for destructing, vent valve is connected on the cabinet by the left tube connector that is arranged on the cabinet, and dehydrating breather is connected on the cabinet by the right tube connector that is arranged on the cabinet.
For the convenience that connects, connection balloon valve is communicated with on vent valve and dehydrating breather by the three-port structure that is connected on left tube connector and the right tube connector.
The turnover of gas for convenience, the breathing seat that connects by the pipe joint that is arranged on the cabinet is installed on the cabinet, breathe the bend pipe that seat has 90 °, the two ends Chinese of bend pipe is connected to flange, and the outside of the flange of one end is welded with the retaining air ring of external diameter less than capsule opening part internal diameter.
For the convenience of oiling, oil inlet and outlet is communicated with the oiling ball valve.
For the sealing property of integral body, the front end of cabinet is provided with panel, and the front end of panel is provided with front shroud, and the cabinet rear end is provided with base plate, and the rear end of base plate is provided with back shroud.
For integrally-built balance, the cabinet lower end is provided with the cabinet pin, and the cabinet pin comprises that the horizontal profile that is welded on the cabinet lower end claims feet of " ten " word and the horizontal support member that is used to connect, and feet and horizontal support member connect by fixture.
Be communicated with transformer for convenience, the cabinet lower end is connected with main connecting line, and main connecting line comprises following bend pipe, butterfly valve, horizontal connecting leg, Buchholz relay, side bend and the vertical bend pipe down of the connection cabinet that connects successively.
The beneficial effects of the utility model are, a kind of capsule-type oil conservator that vacuumizes of the present utility model, solved the problem that original capsule oil conservator can not vacuumize with the transformer body, can effectively remove in the oiling process gas content of oil and device body built-in electrical insulation corner and choke with resentment, improve transformer insulated electric strength.Owing to strengthened oily protection, thereby delayed the ager process of insulating oil and solid insulation, reduced the oil affair nursing work load in the runtime simultaneously.Simultaneously, because adopting, such oil conservator has high low oil level warning contact pointer type fuel level indicator, and can be with the signal is far passed to central control room, be convenient to unattended operation and operation maintenance personnel and in time understand oil conservator internal memory oil mass, thereby guarantee that the transformer ' s type product can long-term safety move, reduced the cost of making, and easy construction.Because the capsule-type oil conservator with respect to expansion of metal formula oil conservator, has under the prerequisite of identical function, the characteristics that have low, the easy replacing of cost to safeguard are so be widely adopted in big or middle capacity transformer.
