Abstract
The utility model discloses an extension structure of an insulating oil sampling valve of a converter transformer. In the structure, an adapter is arranged on the insulating oil sampling valve of the converter transformer and connected with an extension pipe to a position easy to sample on the side surface of the converter transformer, and the outlet of the extension pipe is provided with a new sampling valve and a plug. The structure ensures that a special tool is not needed while sampling so as to be more convenient for sampling compared with an original sampling valve; and a sampling procedure is reduced on the site; and the special tool is not needed to connect a glass needle cylinder, left oil stains are fewer, and the structure is convenient to clean, thereby the working time is saved, and the working efficiency is improved.
Description
Technical field
The utility model belongs to power equipment maintenance technology field, especially relates to a kind of converter power transformer insulating oil sampling valve door extending structure.
Background technology
Converter power transformer is the large-scale oil-filled equipment in the electric system, built-in electrical insulation oil has effects such as insulation, heat radiation, and the analysis of insulating oil oil chromatography is easy to find the converter power transformer internal fault, as discharging, making moist, so very important to the regular oil chromatography analysis of converter power transformer.Converter power transformer all has special-purpose sample cock, two valves (top sample cock, bottom sample cock) or three valves (top sample cock, middle part sample cock, bottom sample cock) are generally arranged, and all sample cocks all concentrates on a position.
Noise is bigger during the converter power transformer operation, generally at the converter power transformer upside and the outside BOX-IN is installed during the current conversion station design and construction, and converter power transformer and BOX-IN space is very little.In case the insulating oil sampling valve door concentrates on outside the converter power transformer, comparatively difficult when then the insulating oil sampling is carried out at the scene, be unfavorable for operation, and on-the-spot greasy dirt is difficult to handle after the sampling, the misleading personnel of patrolling and examining think sample cock seepage oil.
Converter power transformer generally all is equipped with patrols and examines passage, and the part converter power transformer is patrolled and examined passage and just in time is placed in insulating oil sampling valve door top, also comparatively difficult when the insulating oil sampling is carried out at the scene, is unfavorable for operation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of insulating oil sampling operation simple, and the converter power transformer converter power transformer insulating oil sampling valve door extending structure of greasy dirt is on every side reduced in the sampling back.
The technical solution of the utility model is achieved in that a kind of converter power transformer insulating oil sampling valve door extending structure, it is characterized in that: an adapter is installed on the former sample cock of converter power transformer insulating oil, adapter connects a prolongation and manages the position that the converter power transformer side is easy to take a sample, and establishes new sample cock and plug in prolongation pipe exit.
For rainproof, help equipment control, prevent new sample cock by maloperation, on new sample cock, install a glass rain cover additional.
The utlity model has following advantage: the sample position spaciousness, sampling is convenient, the new sample cock oil-out internal diameter and the glass syringe glass draught animals of taking a sample directly can be provided with consistently, need not to use specific purpose tool during sampling, simple to operate, and the more former sample cock of new sample cock operation is convenient.The sampling operation has been reduced at the scene, need not to use specific purpose tool so that connect the glass syringe, and it is few and be convenient to cleaning to leave over greasy dirt, has saved the working time, has improved work efficiency.

Fig. 2 is the utility model converter power transformer insulating oil sampling valve door extending structure synoptic diagram.
Embodiment
As depicted in figs. 1 and 2, a kind of converter power transformer insulating oil sampling valve door extending structure, it is that an adapter 2 is installed on the former sample cock 1 of converter power transformer insulating oil, adapter 2 connects one and prolongs pipe 3 positions that are easy to take a sample to the converter power transformer side, establishes new sample cock 4 and plug 5 in prolongation pipe exit.For rainproof, help equipment control, prevent new sample cock 4 by maloperation, on new sample cock 4, installing a glass rain cover 6 additional.
Claims (2)
1. converter power transformer insulating oil sampling valve door extending structure, it is characterized in that: go up at the former sample cock of converter power transformer insulating oil (1) adapter (2) is installed, adapter (2) connects one and prolongs the position that pipe (3) is easy to take a sample to the converter power transformer side, establishes new sample cock (4) and plug (5) in prolongation pipe (3) exit.
2. according to the described converter power transformer insulating oil sampling valve of claim 1 door extending structure, it is characterized in that: on new sample cock (4), install a glass rain cover (6) additional.
