The vacuum oil injection machine is characterized in that the oil tank is erected on a frame, the constant-temperature control box is arranged on the frame and wraps the oil tank, a control panel is arranged on the outside of the constant-temperature control box, and a temperature gauge, a temperature controller and a switch are arranged on the control panel. The vacuum oil injection machine has the advantages that the constant-temperature control box is arranged on the outside of the oil tank, the temperature of oil in the oil tank can be adjusted according to change of the external environmental temperature, the oil in the oil tank can keep at the constant temperature, and the problem that an existing oil tank is blocked due to excessively low temperature of existing oil and decrease of flow rate of the existing oil or danger coefficients are greatly increased in oil injection processes due to excessively high temperature of the existing oil can be solved.
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 with insulating box.
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, due to the restriction by external condition, the oil liquid temperature stored in the fuel reserve tank of vacuum oil-injecting machine can be low or high by the exception running of ambient temperature or machine, when oil liquid temperature is too low, during oiling, the flow velocity of fluid reduces, also can blocking pipe time serious, when oil liquid temperature is too high, can there is certain danger again in oiling.
Summary of the invention
The invention provides a kind of vacuum oil-injecting machine with insulating box, object solves prior art problem, provides a kind of safe and efficient, and can keep the vacuum oil-injecting machine of constant temperature.
The present invention deal with problems adopt technical scheme be:
A kind of vacuum oil-injecting machine with insulating box, 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 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, 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.
Beneficial effect of the present invention: because oil tank peripheral hardware of the present invention has constant temperature control box can regulate the temperature of oil tank inner fluid according to the change of ambient temperature, the fluid in oil tank is made to keep a stationary temperature, do not cause the temperature of fluid too low, flows decrease blocking oil tank, or the too high danger coefficient of oil filling flow process that makes of the temperature of fluid improves greatly.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
A kind of vacuum oil-injecting machine with insulating box 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 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, 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, the temperature in insulating box is controlled by temperature controller, oil tank peripheral hardware has constant temperature control box can regulate the temperature of oil tank inner fluid according to the change of ambient temperature, the fluid in oil tank is made to keep a stationary temperature, do not cause the temperature of fluid too low, flows decrease blocking oil tank, or the too high danger coefficient of oil filling flow process that makes of the temperature of fluid improves greatly.
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, oil tank 1 is filled 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, again to needing the equipment of oiling to vacuumize, object is taken out by the bubble in equipment, the equipment cavity zone of making is in vacuum state, when the temperature of external environment reduces, the fluid viscosity stored in oil tank 1 increases, the mobility of fluid is reduced, reduce the operating efficiency of oiling machine, the drain pipe of oiling machine is easily blocked by tough fluid simultaneously, circulate not smooth, the radiator valve 8 be now set in outside oil tank 1 controls to start working by control panel 9, the oil liquid temperature stored in oil tank 1 is raised, viscosity reduces, circulate smooth and easy, improve the operating efficiency of oiling machine, when oil liquid temperature because oiling machine fault or the excessive rising of oil liquid pressure make, radiator valve 8 is controlled by control panel 9, make radiator valve 8 control to reduce the temperature of fluid, reduce the potential safety hazard caused because oil liquid temperature is too high, ensure the personal safety of workman in the process of operation.
