Description
Technical Field
The utility model relates to a transformer stores up oil tank technical field, concretely relates to transformer is with improving structure of storing up oil tank antithetical couplet pipe.
Background
In the operation process of the power transformer, the volume of oil can expand with heat and contract with cold along with the change of temperature and load, so that the capsule type oil conservator meets the requirement of the power transformer in daily operation. The capsule type oil conservator mainly comprises a breathing capsule, and can isolate dry air from transformer oil and prevent oil deterioration caused by air contact. And the integrity and safety of the capsule cannot be checked by human judgment in daily operation. Along with the development of equipment, the appearance of the capsule leakage detection device fills the gap of monitoring the capsule of the transformer oil conservator. For the safe operation of the capsule leakage detection device, a reasonable pipeline and correct operation successfully become a problem to be solved by transformer designers.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an improved structure of oil conservator union pipe for transformer.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an improved structure of an oil conservator connecting pipe for a transformer comprises a breathing pipe, a sealing valve, an exhaust valve, a three-way valve, an oil injection valve, an oil conservator and an oil conservator capsule arranged in the oil conservator; wherein,
the one end and the oil conservator capsule intercommunication of respiratory tube, the other end and three way valve's first port intercommunication, three way valve's second port and third port communicate with air vent valve and sealing valve respectively, and sealing valve and oil conservator intercommunication, and sealing valve sets up at the oil conservator top, and the oil conservator top still communicates there is capsule leak hunting device, annotates oil valve and oil conservator intercommunication.
The utility model discloses a further improvement lies in, and sealing valve and exhaust valve all upwards set up perpendicularly.
The utility model discloses a further improvement lies in, still include capsule leak hunting device with protecting the frame, its setting is under capsule leak hunting device.
The utility model discloses a further improvement lies in, still include the manometer with the respiratory tube intercommunication.
The utility model discloses further improvement lies in, and the oiling valve setting is in the bottom of storing up the oil tank.
The utility model discloses further improvement lies in, and the bottom of storing up the oil tank is provided with the landing leg.
The utility model discloses have following advantage:
the utility model provides a pair of transformer is with improvement structure of oil conservator allies oneself with pipe combines supporting operation requirement, can effectually get rid of the residual gas in the transformer oil conservator, through the real running state that embodies the transformer oil conservator of capsule leak hunting device, has realized the alarming function of capsule leak hunting device when the oil conservator capsule is damaged and the oil conservator cabinet body seepage, has avoided because gaseous row of oiling in-process causes false alarm as far as possible. Through the mutual cooperation of sealing valve and air discharge valve, the residual gas in the oil conservator in the conventional oiling process of discharge that can the very big degree to fine maintenance stores up the holistic gas tightness of oil conservator.
Furthermore, the situation that residual gas cannot be exhausted due to the design that the outlet of the vertical upward sealing valve and the vertical upward exhaust valve faces downwards is avoided, and the residual gas in the oil conservator and in the pipeline is exhausted by utilizing the natural law that air floats upwards in transformer oil.
Further, capsule leak hunting device is with protecting frame setting under capsule leak hunting device, prevents that the oil conservator capsule from blockking up the installing port of capsule leak hunting device because of the expansion.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-pressure gauge, 2-sealing valve, 3-exhaust valve, 4-three-way valve, 5-oil injection valve, 6-capsule leakage detection device, 7-protective frame for capsule leakage detection device, and 8-oil conservator capsule.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to an improved structure of a transformer oil conservator union pipe, which comprises a breathing pipe, a sealing valve 2, an exhaust valve 3, a three-way valve 4, an oil injection valve 5, an oil conservator and an oil conservator capsule 8 arranged in the oil conservator; wherein, the one end and the oil conservator capsule 8 intercommunication of respiratory tube, the other end and three way valve 4's first port intercommunication, three way valve 4's second port and third port communicate with air vent valve 3 and sealing valve 2 respectively, and sealing valve 2 and oil conservator intercommunication, and sealing valve 2 sets up at the oil conservator top, and the oil conservator top still communicates there is capsule leak hunting device 6, and oiling valve 5 and oil conservator intercommunication.
Furthermore, the utility model discloses still include capsule leak hunting device with protecting frame 7, it sets up under capsule leak hunting device 6, still include the manometer 1 with the breathing tube intercommunication.
When the device works, the tightness of the oil conservator and the connecting pipe is firstly checked to ensure that no leakage exists. Then opening valves at a sealing valve 2, an exhaust valve 3, a three-way valve 4 and an oil injection valve 5, installing a pressure gauge 1 at a breathing pipe, injecting oil from the oil injection valve 5 to a normal oil level, closing the oil injection valve 5, vacuumizing from the exhaust valve 3, closing the exhaust valve 3 and the three-way valve 4 after reaching a specified vacuum degree, installing a cover plate with an air release plug at the exhaust valve 3, slowly opening the valve at the pressure gauge, and slowly introducing atmosphere into an oil storage cabinet capsule 8 to slowly expand the oil storage cabinet capsule 8 to fill the cavity of the whole oil storage cabinet; observing the oil level condition in the capsule leakage detecting device 6 after the oil conservator capsule 8 is completely vacuumed; if the oil is not full, pressurizing at the pressure gauge 1, opening a vent plug at the top end of the capsule leakage detection device 6, discharging residual gas of the oil storage cabinet from the top of the capsule leakage detection device 6 until the vent plug continuously bursts the oil, and closing the vent plug; then opening the air release plug at the upper part of the exhaust valve 3, discharging residual gas until oil continuously emerges from the air release plug, and closing the air release plug; then the sealing valve 2 is closed, then the exhaust valve 3 is closed, and finally the external pressure is removed.
