Device for obtaining carrier gas for monitoring oil gases from transformer on site

Abstract

The invention discloses a device for obtaining carrier gas for monitoring oil gases from transformer on site. The carrier gas device comprises a transformer, and is characterized by further comprising a gas filtering module, a miniature reciprocating piston air compressor, a gas drying module, a gas storing module, a control module and a carrier gas regenerating module, wherein a gas inlet port A of the gas filtering module is communicated with a transformer on-site environment through a gas pipe, a gas outlet end hole C of the gas filtering module is connected with a gas inlet port E of the miniature reciprocating piston air compressor through a gas pipe; a gas outlet port N of the gas storing module is connected with a gas inlet end of the monitoring device through a gas pipe. The carrier gas device is simple in structure, stable in performance and low in cost; carrier gas required by a gas monitoring device in transformer oil is made by using air in the transformer on-site environment, thus the maintenance cost and workload for periodically replacing a carrier gas bottle for the gas monitoring device in the transformer oil are reduced, and the sampling monitoring frequency and the monitoring stability of an existing monitoring device are favorably improved. The carrier gas device is suitable for obtaining the carrier gas for monitoring the oil gases from the transformer on site.

Description

technical field [0001] The invention relates to the field of transformer monitoring in smart grids, in particular to a gas-carrying device for taking insulating oil and gas for monitoring on-site from transformers. Background technique [0002] The gas online monitoring technology of transformer insulating oil is to directly use the device installed on the running transformer to detect and analyze the dissolved gas in the insulating oil, so it can obtain the status information of the transformer in real time and provide auxiliary decision-making for the operation and maintenance of the equipment. [0003] The on-line monitoring technology of dissolved gas in transformer insulating oil has been developed for decades, and many companies at home and abroad have introduced many kinds of on-line monitoring devices; and they have been widely used. Among them, most online monitoring devices need to use purified air or high-purity N2 as carrier gas, and consume the dissolved gas in ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned existing monitoring devices meet the online monitoring requirements of gas in oil in the power system to a certain extent, there are still some deficiencies: Carrier gas filled with compressed gas cylinders - pure air will increase the complexity of the monitoring device and increase the maintenance workload

When the carrier gas is insufficient or there is no carrier gas, the monitoring device will not work normally, which will affect the stability of the monitoring device

Periodic replacement will cost money and take human resource costs
