Abstract
The utility model discloses an oil sampling device of an on-load tap changer oil tank. The oil sampling device is characterized by comprising a flange, an oil outlet pipe and a pipe cap, wherein an overflow hole is formed in the middle of the flange; the oil outlet pipe is in a hollow pipe; one end of the oil outlet pipe is an oil inlet, and the other end of the oil outlet pipe is an oil outlet; the oil inlet end of the oil outlet pipe is located at the overflow hole of the flange and is in fixed sealing connection with the flange; one end of the pipe cap is plugged; and the pipe cap is in sealing connection with the oil outlet end of the oil outlet pipe. When the oil sampling device is used, the pipe cap is taken down, an oil sample container is placed below the oil outlet pipe, and a pull handle is rotated to open the valve for sampling; and after sampling, the operations are performed reversely. The oil sampling device disclosed by the utility model has the advantages of simple structure and convenience in operation.
Description
Technical field
The utility model relates to power transformer to be safeguarded, is a kind of oil sampling device for the on-load voltage regulating switch fuel tank.
Background technology
On-load tap-changer of transformer is the master element that guarantees the power transformer output quality of power supply, for guaranteeing the safe operation of power transformer, needs regular oil sampling to the on-load voltage regulating switch fuel tank to detect.During the oil sampling of existing on-load voltage regulating switch fuel tank, can carry out after need pulling down the flange of on-load voltage regulating switch fuel tank sampling port, both time-consuming was wasted transformer oil again, and very easily caused seal gasket to seal not in place and initiating failure in the installation after sampling.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the shortcoming of prior art, provide that a kind of flange that needn't pull down on-load voltage regulating switch fuel tank sampling port is directly taken a sample, the oil sampling device of simple in structure, easy to operate on-load voltage regulating switch fuel tank.
The scheme of the utility model technical solution problem is: a kind of oil sampling device of on-load voltage regulating switch fuel tank, it is characterized in that: it comprises flange, flowline and pipe cap, flowing hole is set in the middle of the described flange, described flowline is hollow tubular, one end is the oil product entrance, and the other end is the oil product outlet, and the oil product inlet end of flowline places flowing hole place and the flange seal of flange to be connected, described pipe cap one end shutoff, the oil product endpiece of pipe cap and flowline is tightly connected.
The oil sampling device of the utility model on-load voltage regulating switch fuel tank, its sealing is connected on the valve of on-load voltage regulating switch fuel tank sampling port setting, flowline can be to oil sampling when not pulling down flange, pipe cap can be when not taking a sample the shutoff flowline, guarantee cleaning in the flowline, avoid oil product through the flowline water clock.During use, take off pipe cap, the sample container of oil product is placed the flowline below, the rotation handle is opened valve and can be taken a sample, after the sampling, and the reverse rotation handle, valve-off is removed container, sets up pipe cap.Has simple in structure, easy to operate advantage.

Fig. 2 is the oil sampling Unit Installation synoptic diagram of the utility model on-load voltage regulating switch fuel tank;
Fig. 3 looks cross-sectional schematic for the master of embodiment.
Among the figure: 1 flowline, 2 pipe caps, the outlet of 3 oil products, 4 oil product entrances, 5 flanges, 6 valves, 7 handles.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1～Fig. 2, the oil sampling device of the utility model on-load voltage regulating switch fuel tank, it is characterized in that: it comprises flange 5, flowline 1 and pipe cap 2, in the middle of the described flange 5 flowing hole is set, described flowline 1 is hollow tubular, and an end is oil product entrance 4, the other end is oil product outlet 3, the oil product inlet end of flowline 1 places the flowing hole place of flange 5 and flange 5 sealings to be connected, described pipe cap 2 one end shutoff, and pipe cap 2 is tightly connected with the oil product endpiece of flowline 1.
With reference to Fig. 3, in the present embodiment, flowline 1 adopts thread seal to be connected with flange 5, and flowline 1 adopts with pipe cap 2 and is threaded and the built-in sealing gasket sealing of pipe cap.The oil sampling device sealing of on-load voltage regulating switch fuel tank is connected on the valve 6 of on-load voltage regulating switch fuel tank sampling port setting, flowline 1 can be to oil sampling when not pulling down flange 5, pipe cap 2 can be when not taking a sample shutoff flowline 1, guarantee the cleaning inside of flowline 1, avoid oil product through flowline 1 water clock.During use, take off pipe cap 2, the sample container of sample is placed flowline 1 below, rotation handle 7 is opened valve 6 and can be taken a sample, after the sampling, and reverse rotation handle 7, valve-off 6 is removed container, sets up pipe cap 2.
