[background technology]
At present; Safely and steadily run in order to ensure transformer, need usually regularly transformer oil to be carried out the analysis of each item physical and chemical index, because the oil sample that in analytic process, extracts requires very high; Existing tool implementation not the collection under the vacuum state, cause really data to react accurately.Because this work requires very high to the oil sample of taking; Gather oil sample and should avoid the duration that contacts with atmosphere as much as possible; Should reduce as far as possible and sneak into too much " being harmful to " gas in the oil, so that warranty test result's accuracy, when existing instrument is taken a sample; Sometimes be to survey an accurate numerical value to need repeatedly round transformer station scene to test the laboratory with oiling; Not only take a lot of work, time-consuming, the effort, also can cause simultaneously moving the correct judgement that whether can normally move equipment, thereby influence the safe and stable operation of transformer equipment with the maintainer.
[summary of the invention]
In order to overcome the deficiency in the background technology; The utility model discloses a kind of vacuum oil sample collector of transformer; The vacuum oil sample collector of said transformer has utilized the principle of syringe; Through the only import but no export of retaining valve B and the only export but no import of retaining valve A, utilize circular jacking block to-and-fro movement just with the oil sample of transformer not ingress of air directly send into container, prevented the purpose of oil sample contact atmosphere effectively.
In order to realize said goal of the invention, the utility model adopts following technical scheme:
A kind of vacuum oil sample collector of transformer comprises body, retaining valve B, rubber ring, connecting link, retaining valve A, bonnet, handle, pipe and container, is provided with connector at the front end of body; Retaining valve B is arranged in the gross porosity of connector, and the front end of connecting link is provided with circular jacking block, and rubber ring is socketed in the outer rim of jacking block; Be provided with retaining valve A in the through hole of connecting link; Cavity wall in the jacking block of said connecting link and the body closely cooperates, and connects bonnet at the rear portion of body, is connected with an end of handle after the perforation that postoperculum was provided with after connecting link passed; The other end at handle is provided with pipe, the external container of pipe; Wherein retaining valve B is an only import but no export, and retaining valve A is an only export but no import; Through hole in the connecting link, form oil sample path by the cavity in the body to container with screw and pipe in the handle.
The vacuum oil sample collector of described transformer, the rear end outer wall of body is provided with external thread, is provided with internal thread, said external thread and the wire connection of wire connection internal thread in the front inner wall of bonnet.
The vacuum oil sample collector of described transformer is set to the end gross porosity in the connector of body front end, cavity one side is set to pore.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
The vacuum oil sample collector of said transformer has utilized the principle of syringe; Through the retaining valve B of only import but no export is set in connector; The retaining valve A of only export but no import is set in the connecting link front end through hole that leads to container; Under the drive of handle circular jacking block to-and-fro movement just with connector attend oil sample that the pipeline of UNICOM's transformer extracts not ingress of air directly send into container, realized the vacuum drawn of oil sample, prevented the purpose of oil sample contact atmosphere effectively; The utility model is simple in structure, especially is fit to the transformer oil sample and gathers used.
