The vacuum oil injection machine is characterized in that the oil tank is supported on a frame, the top of the oil tank is provided with a pressure controller, the pressure controller is connected with an inner cavity of the oil tank and connected with the alarm device, a high- and low-pressure control unit is arranged in the pressure controller. The pressure controller and the alarm device are arranged on the top of the oil tank, so that when the pressure is lower than the set minimal pressure or higher than the set maximum pressure, the alarm device can send an alarm to prompt operators of breakdown of the oil injection machine and demands for overhauling, and safety potential hazards are eliminated.
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 pressure warning unit.
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, vacuum oil-injecting machine pressure need artificial Real-Time Monitoring, manually slightly monitoring is omitted and is just likely caused industrial accident.
Summary of the invention
The utility model provides a kind of vacuum oil-injecting machine with pressure warning unit, and object is to solve prior art problem, provides a kind of safe and efficient, the vacuum oil-injecting machine that automatic monitoring measuring pressure is reported to the police.
The utility model deal with problems adopt technical scheme be:
A kind of vacuum oil-injecting machine with pressure warning unit, 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, 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, the top of oil tank is provided with pressure controller, pressure controller is communicated with the inner chamber of oil tank, and pressure controller connects warning device.
In described pressure controller, be provided with high pressure and low voltage control unit.
The beneficial effects of the utility model: because oil tank of the present utility model top is provided with pressure controller and warning device, when the pressure in oil tank lower than set minimum pressure or pressure higher than set maximum pressure time, warning device warning reminding staff oiling machine fault, need maintenance, get rid of potential safety hazard.

In figure: 1, oil tank; 2, oil inlet pipe; 3, gear pump; 4, flowline; 5, accurate filter; 6, vacuum pump; 7, vehicle frame; 8, pressure controller; 9, warning device.
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 pressure warning unit 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, 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, the top of oil tank 1 is provided with pressure controller 8, pressure controller 8 is communicated with oil tank inner chamber, pressure controller 8 connects warning device 9, in described pressure controller 8, be provided with high pressure and low voltage control unit, when pressure lower than set minimum pressure or pressure higher than set maximum pressure time, pressure controller 8 is by the switch opens of warning device 9, warning device 9 warning reminding staff oiling machine faults, need maintenance, get rid of potential safety hazard.
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, when the low pressure alarm device 9 that the pressure in oil tank 1 is set lower than the interior low voltage control of pressure controller 8 unit is reported to the police, the high pressure alarm device 9 of setting higher than pressure controller 8 inner high voltage control units when the pressure in oil tank 1 also starts to report to the police, warning device 9 warning reminding staff oiling machine faults, need maintenance, get rid of potential safety hazard.
For making any technical staff in this area realize or to use the utility model, above disclosed embodiment is described.To those skilled in the art; The various alter modes of these embodiment are all apparent, and General Principle defined herein also can be applicable to other embodiment on the basis that does not depart from spirit of the present disclosure and protection range.Therefore, the embodiment that the disclosure is not limited to provide herein, but consistent with the widest scope of the disclosed principle of the application and novel features.
