Abstract
A flow limiting oil pump with a mutual inductor comprises a flow limiting oil pump and a mutual inductor, wherein the flow limiting oil pump and the mutual inductor are connected through a pipeline. The pipeline is provided with a vent hole and a vent valve, valves are respectively arranged on the pipeline at the two ends of the vent hole, and the height of the vent hole in the pipeline is higher than the height of any one of the valves. The flow limiting oil pump with the mutual inductor has the advantages that firstly, a sampling test and supplement of insulating oil are completed under the condition that power of less-oil devices including the mutual inductor and the like is not cut off, frequency of power cut of the devices is effectively reduced, and power supply reliability is promoted, and secondly, the time of the supplement of the insulating oil is short, and supplement work for a plurality group of mutual inductors can be completed in a short time, and thirdly, the flow limiting oil pump with the mutual inductor is simple, portable and convenient to carry, work occupation space is small, load of a worker working outside for carrying the device is reduced, and the timely supplement of the less-oil devices including the mutual inductors and the like after the sampling of the insulating oil is achieved.
Description
Technical field
The utility model relates to the limit flow oil pump with mutual inductor, is a kind of charged additional device of insulating oil after drawing oil sample for the few oily equipment live of electric power system.
Background technique
In the process of online repairing, after repair based on condition of component work is carried out, for effectively holding equipment state, reduce and have a power failure, take the charging test mode just becoming active demand, but limited owing to filling insulating oil for few oily equipment such as mutual inductors, just be down to low spot through oil level behind several sub-samplings, repairing must have a power failure equipment, otherwise not only can't carry out sampling test, also affect equipment safety operation, so the device that exploitation has the live line oil make-up function guarantees that to instant assurance equipment state power grid operation is significant.
The model utility content
The purpose of this utility model is to address the above problem, and realizes the online live line oil make-up of mutual inductor with a kind of simple in structure, oil pump little, flexible usefulness that is convenient for carrying, takes up room.
The technical solution adopted in the utility model is:
Limit flow oil pump with mutual inductor, comprise limit flow oil pump and mutual inductor, be connected by pipeline between described limit flow oil pump and the mutual inductor, and be provided with exhaust port and outlet valve at described pipeline, pipeline at described exhaust port two ends is respectively equipped with valve, and the pipeline height at described exhaust port place is higher than the height of any one described valve.
The utlity model has following advantages:
1, under few oily equipment live state such as mutual inductor, finishes the insulating oil sampling test and insulating oil replenishes.Effectively minimizing equipment frequency of power cut improves power supply reliability.
2, the used time weak point of supplementary insulation oil can be finished many group mutual inductor repairing work at short notice.
3, simply light, easy to carry, the little heavy burden that has alleviated Portable device when the staff goes out work that takes up room can in time replenish after the apparatus insulated oil sampling of few oil such as mutual inductor.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described limit flow oil pump with mutual inductor of the utility model embodiment.
Embodiment
As shown in Figure 1, the described limit flow oil pump with mutual inductor of the utility model embodiment, be used for being connected with fuel reserve tank 3, comprise limit flow oil pump 2 and mutual inductor 1, be connected by pipeline between described limit flow oil pump 2 and the mutual inductor 1, and be provided with exhaust port and outlet valve 5 at described pipeline, and the pipeline at described exhaust port two ends is respectively equipped with valve 4, and the pipeline height at described exhaust port place is higher than the height of any one described valve 4.
The utlity model has following advantages:
1, under few oily equipment live state such as mutual inductor, finishes the insulating oil sampling test and insulating oil replenishes.Effectively minimizing equipment frequency of power cut improves power supply reliability.
2, the used time weak point of supplementary insulation oil can be finished many group mutual inductor repairing work at short notice.
3, simply light, easy to carry, the little heavy burden that has alleviated Portable device when the staff goes out work that takes up room can in time replenish after the apparatus insulated oil sampling of few oil such as mutual inductor.
