Abstract

A transformer oil feeding-draining switching apparatus is characterized in that a group of oil-feeding pipes and a group of oil-draining pipes are respectively adopted; wherein, one group of the oil pipes comprises two oil-feeding pipes and the other group comprises two oil-draining pipes; furthermore, two ends of one oil-feeding pipe are respectively communicated with a transformer port and an oil-draining port of an oil filter; two ends of the other oil-feeding pipe are respectively communicated with an oil tank port and an oil feeding port of the oil filter. Two ends of one oil-draining pipe are respectively communicated with a transformer port and the oil-feeding port of the oil filter, and the two ends of the other oil-draining pipe are respectively communicated with an oil tank port and the oil-draining port of the oil filter. Simultaneously, a control valve is arranged on each of the oil-feeding pipes and the oil-draining pipes. Therefore, the opening and closing of the corresponding control valve during the switching process can conveniently open or close the oil-feeding work channel and the oil-draining work channel without pulling and inserting the oil pipe. The switching apparatus not only can avoid leakage during the whole oil feeding-draining switching process, but also has easy operation process and high work efficiency, and the labor intensity of workers can be largely reduced.

Description

A kind of transformer notes, the oil stream switching device shifter of draining the oil

Technical field

The utility model relates to the switching device shifter that a kind of controlling liquid flows to, particularly a kind of transformer notes, the oil stream switching device shifter of draining the oil.

Background technology

Normally used oil-filled transformer, when maintenance need row, put transformer oil or the defective need of transformer oil are annotated in transformer, when draining the oil, all need oil to be carried out purified treatment by oil filter, and existing oil filter, no matter be plate oil-filter or vacuum oil-filter, because of the unicity of its oil strain machine oil flow path direction, the switching that transformer is annotated, drained the oil also must lean on the oil pipe that is connected between artificial plug transformer and the oil filter to realize.Not only operation is more loaded down with trivial details, has prolonged the activity duration, has caused the inconvenience of work, and the remaining pressure of oil filter also can make ducted oil leakage when operation, has both caused waste, has polluted environment again.

The utility model content

The utility model is the deficiency that exists in the above-mentioned background technology, provide a kind of easy and simple to handle, high efficiency can thoroughly be avoided transformer notes, the oil leakage phenomenon of draining the oil, and need not the transformer notes that the plug oil pipe can be finished notes, the stream oil of draining the oil switches, the oily stream switching device shifter of draining the oil.

Its concrete solution is: adopt the oiling and the two groups of oil pipes of draining the oil, wherein one group of oil pipe is made of two oil fuel tubes, and another group oil pipe is made of two drain lines, and, the two ends of one oil fuel tube are exported oily interface with transformer interface and oil filter respectively and are communicated with, and the two ends of another oil fuel tube are communicated with fuel tank interface and oil filter oil-feed interface respectively.And wherein the two ends of a drain line are communicated with transformer interface and oil filter oil-feed interface respectively, and the two ends of another drain line are exported oily interface with fuel tank interface and oil filter respectively and are communicated with.Simultaneously, be provided with control valve on each oil fuel tube and the drain line.Make it annotate, drain the oil when switching, only need change state that opens and closes that each group goes up control valve (that is: close wherein control valve on one group of oil pipe, and open the control valve on another group oil pipe) can realize.

The utility model adopts its two groups of oil pipes that are provided with control valve to realize the transformer notes, the switching of draining the oil, make and in handoff procedure, do not need the plug oil pipe, only by opening, close the control corresponding valve and can open or close the oiling service aisle and the service aisle of draining the oil easily, successfully finish notes, the operation of draining the oil, thereby effectively overcome in the prior art because of pulling out, the draining phenomenon that slotting oil pipe causes, whole notes have been realized, drain the oil ne-leakage in the handoff procedure, both avoided raw-material waste, stopped oil product again to people's injury and to the pollution of operating environment, simultaneously, operation also makes working strength of workers alleviate greatly when increasing work efficiency greatly easily.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

In the accompanying drawing, what control valve 3,10,2,11 adopted is break valve, they are connected to oil fuel tube 5,9, on the drain line 4,8, one end of drain line 4 and an end of oil fuel tube 5 all are communicated with transformer interface 1, one end of oil fuel tube 9 and an end of drain line 8 all are communicated with fuel tank interface 12, and the other end of the other end of oil fuel tube 5 and drain line 8 exports oily interface 6 with oil filter and be communicated with, and the other end of the other end of oil fuel tube 9 and drain line 4 is communicated with oil filter oil-feed interface 7.

When implementing the oiling operation, answer opening controlling valve 3,10, simultaneously, closed control valve 2,11, during oiling, transformer oil in the fuel tank can be by oil filter oil-feed interface 7 to oil filter after fuel tank interface 12 is flowed through oil fuel tube 9, and the transformer oil after oil filter purifies again through oil filter export oily interface 6 by oil fuel tube 5 by transformer interface 1 injection transformer; When transformer need be implemented to drain the oil operation, closed control valve 3,10, opening controlling valve 2,11 can make the transformer oil in the transformer be delivered to oil filter through drain line 4, is input in the fuel tank through drain line 8 after purifying by oil filter again.

Claims (1)

1, a kind of transformer is annotated, the oil of draining the oil flows switching device shifter, it is characterized in that adopting oiling and drain the oil two groups of oil pipes, wherein one group of oil pipe is by oil fuel tube (5), (9) constitute, and another group oil pipe is by drain line (4), (8) constitute, and, the two ends of oil fuel tube (5) are exported oily interface (6) with transformer interface (1) and oil filter respectively and are communicated with, the two ends of another oil fuel tube (9) are communicated with fuel tank interface (12) and oil filter oil-feed interface (7) respectively, and the two ends of drain line (4) are communicated with transformer interface (1) and oil filter oil-feed interface (7) respectively, the two ends of another drain line (8) are exported oily interface (6) with fuel tank interface (12) and oil filter respectively and are communicated with, simultaneously, oil fuel tube (5), (9) and drain line (4), (8) be respectively arranged with control valve (3) on, (10, (2), (11).
