Abstract
The utility model relates to an electric appliance detection device and particularly relates to a top oil extraction tool for a casing pipe. The top oil extraction tool comprises a connector, a soft tube, an oil extraction container, a gas cylinder and a guide tube which are arranged on the casing pipe. According to the top oil extraction tool, dry air or high-purity nitrogen is utilized for replacing air in a normal environment to contact with an oil sample in the casing pipe, so that an oil product is prevented from being damped, and the detection accuracy of the oil sample in the casing pipe is improved; the sealing in an oil extraction process can be guaranteed, so that the exposing time of the casing pipe is greatly shortened, the external moisture can be effectively prevented from being diffused into the casing pipe, and the security coefficient of the operation of the casing pipe is improved; a traditional operation manner is changed, i.e., a conventional extraction manner is changed to be an extrusion manner, so that the time is saved, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of electrical device pick-up unit, is specifically related to a kind of sleeve pipe top and gets oily frock.
Background technology
Sleeve pipe is as the important component part of electrical equipment, and its running status is very large on power grid security impact.At present, detecting the method that its running status adopts is to have a power failure to draw oil sample to carry out chromatography component analysis, yet seldom, its normal water cut is often below 10ppm for sleeve pipe oil mass.For getting the product of hydraulic fluid port on sleeve pipe top, generally adopt the open oil of getting, while getting oil, utilize syringe to extract sleeve pipe occipitalia oil sample, now outside air can enter rapidly sleeve pipe, the negative pressure producing while supplementing oil pumping, makes oil product be subject to the impact of external environment, causes detecting data and occurs deviation; When utilizing syringe to get oil, the running time of every phase is generally at 15-20 minute, and sleeve pipe open-assembly time is long, can cause extraneous moisture diffusion to enter, and makes internal wetted, affects its serviceable life.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy and simple to handle and can prevent that the sleeve pipe top that extraneous moisture enters from getting oily frock.
For solving above technical matters, the utility model adopts following technical scheme: the utility model comprises connector, flexible pipe, oil recovery container, gas cylinder and the conduit being arranged on sleeve pipe;
Described connector is provided with axially extending bore, blind hole and connecting hole, and described axially extending bore center line is parallel with described connector center line; Described connecting hole is located at connector rear end, and its center line is vertical with axially extending bore center line; The parallel axially extending bore upper end of being located at of described blind hole, and pass through mutually with connecting hole; Described flexible pipe one end is in axially extending bore immersion sleeve pipe in fluid, and the other end is communicated with oil recovery container; Described conduit one end is communicated with connecting hole, and the other end is communicated with gas cylinder.
Described connector front end is provided with external thread, and is threaded connection with sleeve pipe.
The utility model also comprises valve, and described valve is located on conduit.
Good effect of the present utility model is as follows: the air that the utility model utilizes dry air or high pure nitrogen to replace conventional environment contacts with sleeve pipe oil sample, has reduced oil product and has made moist, and has improved the accuracy that sleeve pipe oil sample detects; The utility model can guarantee to get the sealing in oily process, has greatly reduced the time that sleeve pipe exposes, and can effectively stop extraneous moisture diffusion and enter inside pipe casing, has improved the safety coefficient of sleeve pipe operation; The utility model has changed traditional mode of operation, by extraction-type in the past, changes to extrusion type, has saved the time, improves the efficiency of work.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model connector partly cuts open structural representation;
In the drawings: 1, sleeve pipe, 2 flexible pipes, 3 gas cylinders, 4 conduits, 5 valves, 6 connectors, 7 axially extending bores, 8 blind holes, 9 connecting holes, 10 oil recovery containers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises connector 6, flexible pipe 2, oil recovery container 10, gas cylinder 3 and the conduit 4 being arranged on sleeve pipe 1; Described connector 6 is provided with axially extending bore 7, blind hole 8 and connecting hole 9, and described axially extending bore 7 center lines are parallel with described connector 6 center lines; Described connecting hole 9 is located at connector 6 rear ends, and its center line is vertical with axially extending bore 7 center lines; Parallel axially extending bore 7 upper ends of being located at of described blind hole 8, and pass through mutually with connecting hole 9; Described flexible pipe 2 one end are in axially extending bore 7 immersion sleeve pipes 1 in fluid, and the other end is communicated with oil recovery container 10; Described conduit 4 one end are communicated with connecting hole 9, and the other end is communicated with gas cylinder 3.Described connector 6 front ends are provided with external thread, and are threaded connection with sleeve pipe 1.The utility model also comprises valve 5, and described valve 5 is located on conduit 4.
The utility model is provided with flexible pipe 2 and 4 two pipelines of conduit, and conduit 4 connects gas cylinder 3, and the interior punching of gas cylinder 3 has high pure nitrogen or dry air; The oil level below that the utility model flexible pipe 2 extend into sleeve pipe 1 inside through axially extending bore 7 is for deriving fluid to the container 3 that recovers the oil.
While using the utility model, open the switch of gas cylinder 3, it is inner that the nitrogen in gas cylinder 3 enters sleeve pipe 1 headrest by conduit 4, and the pressure more than inner pasta of sleeve pipe 1 headrest is raise, and fluid is pressed out in oil recovery container 10 by flexible pipe 2.
The utility model substitutes syringe in the past and extracts mode, has reduced the time that in sleeve pipe 1, fluid exposes, and the utility model connector 6 can be manufactured according to the oily interface specification of getting of sleeve pipe 1, makes the utility model can be suitable for the oily interface of getting of multiple sleeve pipe 1.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the utility model principle and spirit, it having been done, within all should being contemplated as falling with claim protection domain of the present utility model.
