Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.
Referring to fig. 1, an online automatic oiling device 15 for a transformer in operation at a low oil level is used for automatically oiling an oil conservator 12, the oil conservator 12 is connected with a body oil level indicator 11 and a gas connecting pipe 13, the gas connecting pipe 13 is connected with a gas relay 14, the automatic oiling device 15 comprises a corrugated oil storage cabinet 1, an oil filling pipeline, an electromagnetic valve 7 and an oiling machine, the electromagnetic valve 7 and the oiling machine are connected to the oil filling pipeline, one end of the oil filling pipeline is connected with an oil outlet of the corrugated oil storage cabinet 1, the other end of the oil filling pipeline is connected with an oil inlet of the oil conservator 12, the electromagnetic valve 7 is installed between the oiling machine and the oil conservator 12, when the body oil level indicator 11 and the gas relay 14 send out oil shortage warning signals, the electromagnetic valve 7 is automatically.
When the body oil level gauge 11 sends an oil level high signal, the oil level of the oil conservator 12 is full, at the moment, the oiling machine stops working, and the oiling process is finished. Install travel switch 2 in the ripple stores up oil tank 1, it is oilless to show ripple oil tank 1 when ripple piece descends and triggers travel switch 2 in the ripple stores up oil tank 1, and the tanker aircraft stop work this moment, and the process of refueling ends.
Specifically, it includes refuel hose one 4, refuel hose two 6 and notes oil pipe 10 to add the oil pipe way, refuel hose one connects ripple and stores up oil tank and tanker aircraft, refuel hose two connection tanker aircraft and solenoid valve, notes oil union coupling solenoid valve and conservator. The oiling machine is a diaphragm pump oiling machine 5. An oil outlet of the corrugated oil conservator 1 is connected with a ball valve I3, a metal connecting pipe 8 is connected between the electromagnetic valve 7 and the oil filling pipe 10, and a ball valve II 9 is connected between the metal connecting pipe 8 and the oil filling pipe 10.
