Problems solved by technology

[0005] In view of the current situation that the existing oil-immersed transformers generally use internal circulation detection for fault gas detection, this detection method actually only uses the concentration of each gas in the oil and the total concentration of combustible gases in the oil as internal faults of the transformer equipment Diagnosis indicators, the problem that the exact concentration values ​​of these gas components cannot be measured separately, the present invention provides a power grid transformer oil safety detection device capable of classifying and targeted detection of samples

Embodiment Construction

[0026] With the rapid development of my country's electric power to large power grids, large units, high capacity and high voltage levels, higher and higher technical requirements are put forward for the real-time grasp of the operation status of transformers in the power grid. From the classification of insulating media, there are oil-immersed transformers and dry-type transformers. Transformers and gas-insulated transformers, although there are defects in oil-immersed transformers, at present, most power transformers still use transformer oil as insulation and cooling medium. The traditional detection method of dissolved gas in transformer oil of oil-immersed transformers is to use gas chromatography. Analyze the fault gas, mainly for the insulating oil or solid insulator at the fault site will decompose small molecule hydrocarbon gas, these gases include hydrogen, carbon monoxide, methane, ethane, ethylene and acetylene, etc. Dissolved gas in transformer oil is monitored. The ...

Abstract

The invention discloses power grid transformer oil safety detection equipment, which comprises a compensation oil storage tank, an oil change mechanism, a distribution mechanism, a heat treatment mechanism, a carrier gas circulation mechanism, a temperature control mechanism, a waste oil recovery mechanism and a gas detection mechanism. An interlayer is arranged in the middle of a cylinder to forman independent driving chamber located on the lower portion and an independent sampling and supplementing oil chamber located on the upper portion. An electric driving mechanism is installed in the driving chamber, a push rod of the electric driving mechanism extends into the sampling and supplementing oil chamber and is provided with a piston, and the piston divides the sampling and supplementing oil chamber into a lower sampling oil chamber and an upper supplementing oil chamber. After sampled oil of the same batch is divided into a plurality of equal parts, emphasized detection is carriedout on different equal parts. Temperature control mechanisms located in different flat grooves can be arranged differently. The purpose of achieving the maximum detection degree is achieved accordingto the separation performance of different gases. Unimpeded butt joint of sampled oil treatment and a carrier gas channel can be achieved. The operability of fault gas detection is improved, and the detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment safety detection, and in particular relates to safety detection equipment for transformer oil applied to power grid transformers. Background technique [0002] At present, the vast majority of power transformers still use transformer oil as insulation and cooling medium. The advantages of oil-immersed transformers are that transformer oil has good insulation performance, good thermal conductivity, and cheap transformer oil; it can solve the problem of large-capacity heat dissipation and high-voltage insulation of transformers. . However, the disadvantage of oil-immersed transformers is that transformer oil is flammable and may burn and explode when encountering flames; transformer oil needs to be checked regularly; oil-immersed transformers have poor sealing performance and should be aged, and serious oil leakage in operating places affects Equipment operates safely while impacting the...
