The vacuum oil filling machine is characterized in that the oil tank is arranged on a frame, the thermostat is arranged on the frame, wrapped outside the oil tank and externally provided with a control panel, and a thermometer, a temperature controller and a switch are arranged on the control panel. The thermostat is arranged outside the oil tank, so that temperature of oil in the oil tank can be adjusted according to changes of temperature of outside environment, the oil in the oil tank is enabled to be maintained at a constant temperature, and the circumstance that the oil tank is blocked caused by reduction of flowing speed of the oil due to over-low temperature of the oil, or danger coefficient of the oil filling process is greatly increased due to overhigh temperature of the oil is avoided.
Description
Technical field
The utility model relates to a kind of vacuum oil-injecting machine, relates in particular to a kind of vacuum oil-injecting machine with insulating box.
Background technology
In the use procedure of high-tension current inductor or voltage transformer, along with the variation in service time increase and season, the oil level of the insulation oil product in it has decline, needs regularly to its oiling out of doors.For this small amount of oiling, if adopt existing common oiling equipment from the pouring orifice oiling meeting of current transformer or voltage transformer bottom, oil to be contacted with air, easily produce bubble, make the air content in oil, water content increases, thereby the class of insulation of oil product is declined, go back and 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 to have a power failure, when operation, must remove top cover, very trouble, and due to operation aloft, without secure support, has certain risk.
Therefore, developed at present vacuum oil-injecting machine to address the above problem, vacuum oil-injecting machine to vacuumizing in equipment, is now closed oil circuit by vacuum pump, then passes through oil pump smoothly to its oiling.Now vacuum line is closed in and vacuumizes the bubble that simultaneously can eliminate while oiling, and after oiling puts in place, then the gas vacuumizing in gas and the equipment coil of guaranteeing in equipment oil taken out, and has guaranteed the insulating properties of insulating oil.
But, owing to being subject to the restriction of external condition, the oil liquid temperature storing in the fuel reserve tank of vacuum oil-injecting machine can be subject to the abnormal running of ambient temperature or machine low or high, when oil liquid temperature too low, when oiling, the flow velocity of fluid reduces, also can blocking pipe when serious, in the time that oil liquid temperature is too high, can there is again certain danger in oiling.
Summary of the invention
The utility model provides a kind of vacuum oil-injecting machine with insulating box, and object is to solve prior art problem, provides a kind of safe and efficient, and can keep the vacuum oil-injecting machine of constant temperature.
The utility model deal with problems adopt technical scheme be:
A kind of vacuum oil-injecting machine with insulating box, there is oil tank, the napex of oil tank is provided with oil inlet pipe, gear pump, flowline, accurate filter and vacuum pump successively, described gear pump, flowline, vacuum pump are communicated with oil tank respectively, between described oil inlet pipe and gear pump, be provided with oiling conversion equipment, it is characterized in that: described tank rack is located on vehicle frame, and vehicle frame is provided with constant temperature control box, and constant temperature control box is wrapped in outside oil tank.
The housing of described constant temperature control box is provided with control panel, and control panel is provided with thermometer, temperature controller and switch.
The beneficial effects of the utility model: can regulate according to the variation of ambient temperature the temperature of oil tank inner fluid because oil tank peripheral hardware of the present utility model has constant temperature control box, make the fluid in oil tank keep a stationary temperature, do not cause the temperature of fluid too low, the flow velocity obstruction oil tank that slows down, or the excess Temperature of fluid improves the danger coefficient of oil filling flow process greatly.

In figure: 1, oil tank; 2, oil inlet pipe; 3, gear pump; 4, flowline; 5, accurate filter; 6, vacuum pump; 7, vehicle frame; 8, constant temperature control box; 9, control panel.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of vacuum oil-injecting machine with insulating box as shown in Figure 1, there is oil tank 1, the napex 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 gear pump 3, flowline 4, vacuum pump 6 is communicated with oil tank 1 respectively, between described oil inlet pipe 2 and gear pump 3, be provided with oiling conversion equipment, described oil tank 1 is erected on vehicle frame 7, vehicle frame 7 is provided with constant temperature control box 8, constant temperature control box 8 is wrapped in outside oil tank 1, the housing of described constant temperature control box 8 is provided with control panel 9, control panel 9 is provided with thermometer, temperature controller and switch, control the temperature in insulating box by temperature controller, oil tank peripheral hardware has constant temperature control box can regulate according to the variation of ambient temperature the temperature of oil tank inner fluid, make the fluid in oil tank keep a stationary temperature, do not cause the temperature of fluid too low, the flow velocity obstruction oil tank that slows down, or the excess Temperature of fluid improves the danger coefficient of oil filling flow process greatly.
The vacuum oil-injecting machine of the present embodiment is mainly used in to oil-filled transformer, and current transformer injects insulating oil, also can be for oiling operations such as 110-550KV transformer, conduit, loaded switchs.
The feature of the present embodiment: first with vacuum pump, the metal expander top above instrument transformer is extracted into after high vacuum, insulating oil can arrive the required normal oil level of equipment by oil pipe bottom automatic oiling or by oil pump oiling.Its advantage be residual gas in oil-filled equipment particularly the gas between coil first dividend take out, equipment refuels, makeup oil convenience, safety, oil are not polluted, and the original insulation property of energy assurance equipment are that vast power test overhauls the instrument that department welcomes.
In the process of oiling, first by oil-in 2 and gear pump 3, oil tank 1 is filled to oil, move near the equipment that needs oiling filling oily oil tank 1, by flowline 4 and the equipment connection that needs oiling, and by vacuum pump 6, air is extracted out, make equipment in high vacuum state, then open the oiling device that flowline 4 is provided with, start to needing oiling in the equipment of oiling, when the oil level in the equipment that needs oiling reaches behind normal position, again the equipment that needs oiling is vacuumized, object is that the bubble in equipment is taken out, make equipment cavity zone in vacuum state, in the time that the temperature of external environment reduces, the fluid viscosity of oil tank 1 interior storage increases, the mobility of fluid is reduced, reduce the operating efficiency of oiling machine, the drain pipe of oiling machine is easily stopped up by tough fluid simultaneously, circulate not smooth, the radiator valve 8 being now set in outside oil tank 1 is controlled and is started working by control panel 9, the oil liquid temperature of oil tank 1 interior storage is raise, viscosity reduces, circulate smooth and easy, improve the operating efficiency of oiling machine, when oil liquid temperature is because oiling machine fault or the excessive rising of oil liquid pressure make, control radiator valve 8 by control panel 9, make radiator valve 8 control the temperature that reduces fluid, reduce the potential safety hazard causing because oil liquid temperature is too high, ensure the personal safety of workman in the process of operation.
