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 a power grid transformer oil safety detection device, which includes 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 an air detection mechanism. The layer thus forms an independent driving chamber located at the lower part and an independent sampling and replenishing chamber located at the upper part. An electric drive mechanism is installed in the driving chamber. The push rod of the electric driving mechanism extends into the sampling and replenishing chamber and a piston is installed. The oil chamber is separated into the lower sampling oil chamber and the upper compensating oil chamber. The present invention can focus on the detection of different equal parts after the same batch of sampling oil is divided into multiple equal parts, and can have different settings for the temperature control mechanism located in different flat tanks, aiming at the above-mentioned different gases The performance of separation makes it possible to achieve the maximum degree of detection. The sampling process and the carrier gas channel can realize unimpeded docking, improve the operability of fault gas detection, and improve the detection accuracy.

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...
