Description

A quick sampling device for transformer oil

technical field

The utility model relates to a transformer testing device, in particular to a transformer oil rapid sampling device. the

Background technique

During the operation of power transformers, in order to maintain and manage the transformer oil in operation, it is necessary to take oil and gas samples for testing periodically or when there is a latent fault in the equipment. The existing large-scale transformer body oil tank generally has three sampling points: upper, middle and lower. In the actual sampling process, due to the different structures of the sampling heads of various equipment manufacturers, it is often necessary to equip corresponding adapters and connect them in a threaded manner. , one-time sampling is very time-consuming and labor-intensive; and there is a hidden danger of oil leakage. the

Chinese patent CN2497404Y discloses a transformer oil sample valve spiral sampler, one end of the coupling head with a cylindrical cavity is open and the other end is provided with an oil outlet pipe communicating with the cavity, and the inner wall of the coupling head cylinder has energy The internal thread that matches the external thread on the outlet nozzle of the transformer oil sample valve. When in use, unscrew the closing nut on the oil outlet nozzle of the transformer oil sample valve, loosen the oil plug screw, screw the coupling head and the oil outlet nozzle of the oil sample valve, and wait until the air in the cavity and the oil outlet pipe is automatically pushed out, and then insert The head of the sample-containing syringe is inserted into the nozzle of a section of polyvinyl fluoride pipe sleeved with the oil outlet pipe, and the oil will automatically enter the sample-containing syringe. The sampler described in this utility model needs to carry out the operation of thread tightening and unscrewing every time when the sampler takes a sample, which is cumbersome, and it is easy to waste oil when sampling. the
