Description

Technical field:

[0001] The utility model relates to an oil circuit connector, in particular to an oil circuit connector with multiple sampling ports. Background technology:

[0002] In the power industry, in order to ensure the normal operation of large oil-filled electrical equipment (such as transformers), it is necessary to monitor the dissolved gas content of the insulating oil inside, the micro-water content in the oil and other indicators. To achieve this monitoring purpose, the chromatograph host needs to be connected to the oil-filled electrical equipment to facilitate the extraction of the insulating oil for sampling and analysis. However, most oil-filled electrical equipment currently has only one oil circuit connection interface. When other sampling and analysis equipment needs to be added, one oil circuit connection interface cannot achieve this work. Utility model content:

[0003] The technical problem to be solved by the utility model is to provide a multi-sampling port oil circuit connector, which not only realizes the multi-sampling port sampling of oil-filled electrical equipment, but also is convenient and quick to operate.

[0004] The technical solution of this utility model:

[0005] A multi-sampling port oil circuit connector comprises a pipe body, two connecting flanges, N switch valves and N sampling port connecting joints; the two connecting flanges are respectively installed at two ports of the pipe body, and the two connecting flanges can be used to connect with oil-filled electrical equipment and a chromatographic analyzer host respectively; N oil outlets are arranged on the side of the pipe body, the inlets of the N switch valves are respectively connected with the N oil outlets, and the N sampling port connecting joints are respectively installed at the outlets of the N switch valves; N is a natural number greater than or equal to 1.

[0006] N is 2, and the two oil outlets are located on both sides of the tube body.

[0007] An annular sealing groove is provided on the outer end surface of the connecting flange, the annular sealing groove surrounds the outside of the port of the pipe body, and a sealing ring is installed in the annular sealing groove; a bolt mounting through hole is provided on the surface of the connecting flange; the connecting flange is fixed by bolts in the bolt mounting through hole, and the annular sealing groove cooperates with the sealing ring to achieve sealing of the connecting flange to prevent leakage of insulating oil.

[0008] In actual application, the number of oil outlets can be determined according to needs, and the switch valve on each oil outlet independently controls the on and off of the oil outlet.

[0009] Beneficial effects of the utility model:

[0010] The two connecting flanges at both ends of the tube body of the utility model can be connected to the oil-filled electrical equipment and the mainframe of the chromatograph analyzer respectively. At the same time, a plurality of oil outlets are provided on the side of the tube body. The oil outlets are provided with switch valves. A sampling port connecting joint is installed at the outlet of the switch valve, which can be used to connect with other equipment. The utility model can not only meet the monitoring of the oil-filled electrical equipment by the chromatograph analyzer, but also when new equipment needs to be installed to monitor the oil-filled electrical equipment, the sampling oil inlet of the new equipment can be directly connected to the sampling port connecting joint of the utility model through a catheter, which not only realizes the sampling of multiple sampling ports of the oil-filled electrical equipment, but also is convenient and quick to operate.
