Abstract
A vacuum oil filling machine capable of automatically controlling oil level is provided with an oil tank, wherein an oil inlet pipe, a gear pump, an oil outlet pipe, a precision filter and a vacuum pump are sequentially arranged at the top of the oil tank, the oil inlet pipe, the gear pump, the oil outlet pipe and the vacuum pump are communicated with the oil tank, and an oil filling conversion device is arranged between the oil inlet pipe and the gear pump. The vacuum oil filling machine is characterized in that the oil tank is erected on a frame, rolling wheels are arranged at the bottom of the frame, and a liquid level sensor is arranged on the oil inlet pipe and is connected with a magnetic valve of a switch of the oil inlet pipe. When oil in the oil filling machine reaches the position sensed by the liquid lever sensor, the liquid lever sensor controls the magnetic valve of the switch of the oil inlet pipe connected with the liquid lever sensor to be closed, and the purpose of automatic oil level control is achieved.
Description
Technical field
The present invention relates to a kind of vacuum oil-injecting machine, particularly relate to a kind of vacuum oil-injecting machine of automatic control oil level.
Background technology
In the use procedure of high-tension current inductor or voltage transformer out of doors, along with increasing service time and the change in season, the oil level of the insulation oil product in it has decline, needs regular to its oiling.For this small amount of oiling, if adopt existing common oiling equipment oil can be made to contact with air from the pouring orifice oiling bottom current transformer or voltage transformer, easy generation bubble, make the air content in oil, water content increases, thus the class of insulation of oil product is declined, also easily cause insulation fault when bubble enters between mutual inductor coil; And if carry out oiling from the open top of outdoor high-voltage instrument transformer, often need have a power failure, top cover must be removed during operation, extremely bother, and due to operation aloft, without secure support, there is certain risk.
Therefore, be developed vacuum oil-injecting machine to solve the problem, vacuum oil-injecting machine is vacuumized in equipment by vacuum pump, now closes oil circuit, then by oil pump smoothly to its oiling.Now vacuum line is closed in the bubble vacuumized when simultaneously can eliminate oiling, and after oiling puts in place, then vacuumizes and guarantee that the gas in equipment oil and the gas in equipment coil are taken out, and ensure that the insulating properties of insulating oil.
But oiling machine needs artificial supervision in the process of oiling, lose time so very much and manpower and materials.
Summary of the invention
The invention provides a kind of vacuum oil-injecting machine of automatic control oil level, object solves prior art problem, provides a kind of safe and efficient, automatically can control the vacuum oil-injecting machine of oiling oil level.
The present invention deal with problems adopt technical scheme be:
A kind of vacuum oil-injecting machine of automatic control oil level, there is oil tank, the top of oil tank is provided with oil inlet pipe, gear pump, flowline, accurate filter and vacuum pump successively, described oil inlet pipe, gear pump, flowline, vacuum pump are communicated with oil tank respectively, oiling conversion equipment is provided with between described oil inlet pipe and gear pump, it is characterized in that: described tank rack is located on vehicle frame, the bottom of vehicle frame is provided with roller, the pipeline of oil inlet pipe is provided with level sensor, and level sensor is connected with the electromagnetically operated valve of the switch of oil inlet pipe.
Beneficial effect of the present invention: because the present invention is provided with level sensor, when the fluid in oiling machine reaches the position of level sensor induction, level sensor controls the closed electromagnetic valve of the switch of the oil inlet pipe be attached thereto, and realizes the object automatically controlling oil level.
Accompanying drawing explanation

In figure: 1, oil tank; 2, oil inlet pipe; 3, gear pump; 4, flowline; 5, accurate filter; 6, vacuum pump; 7, vehicle frame; 8, roller; 9, level sensor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
A kind of vacuum oil-injecting machine of automatic control oil level as shown in Figure 1, there is oil tank 1, the top of oil tank 1 is provided with oil inlet pipe 2 successively, gear pump 3, flowline 4, accurate filter 5 and vacuum pump 6, described oil inlet pipe 2, gear pump 3, flowline 4, vacuum pump 6 is communicated with oil tank 1 respectively, oiling conversion equipment is provided with between described oil inlet pipe 2 and gear pump 3, described oil tank 1 is erected on vehicle frame 7, the bottom of vehicle frame 7 is provided with roller 8, the pipeline of oil inlet pipe 2 is provided with level sensor 9, level sensor 9 is connected with the electromagnetically operated valve of the switch of oil inlet pipe 2, when the fluid in oiling machine reaches the position of level sensor 9 induction, level sensor 9 controls the closed electromagnetic valve of the switch of the oil inlet pipe 2 be attached thereto, realize the object automatically controlling oil level.
The vacuum oil-injecting machine of the present embodiment is mainly used in oil-filled transformer, and current transformer injects insulating oil, also may be used for the oil injection operation such as 110-550KV transformer, conduit, loaded switch.
The feature of the present embodiment: after first the metal expander top above instrument transformer being extracted into high vacuum with vacuum pump, insulating oil can by oil pipe bottom automatic oiling or by the normal oil level needed for oil pump oiling to equipment.Its advantage be residual gas in the oil-filled equipment gas particularly between coil first dividend take out, equipment refuels, makeup oil convenience, safety, oil are not polluted, and can ensure the original insulation property of equipment, are the instruments that vast power test maintenance department welcomes.
In the process of oiling, first by oil-in 2 and gear pump 3 to oiling in oil tank 1 when the fluid in oil tank 1 reaches the position that level sensor 9 responds to, level sensor 9 controls the closed electromagnetic valve of the switch of the oil inlet pipe 2 be attached thereto, after filling oil, the oil tank 1 filling oil is moved near the equipment needing oiling, by flowline 4 and the equipment connection needing oiling, and by vacuum pump 6, air is extracted out, equipment is made to be in high vacuum state, then the oiling device that flowline 4 is provided with is opened, start oiling in the equipment needing oiling, after the oil level in the equipment needing oiling reaches normal position, vacuumize needing the equipment of oiling, object is taken out by the bubble in equipment, the equipment cavity zone of making is in vacuum state.
For enabling any technical staff in this area realize or use the present invention, above disclosed embodiment is described.To those skilled in the art; The various alter modes of these embodiments are all apparent, and General Principle defined herein also can be applicable to other embodiment on the basis not departing from spirit of the present disclosure and protection range.Therefore, the disclosure is not limited to the embodiment provided herein, but consistent with the widest scope of principle disclosed in the present application and novel features.
