Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] Such as figure 1 , 4 As shown, a transformer respirator online monitor includes a single-chip microcomputer acquisition system, and the single-chip microcomputer acquisition system collects the data of the oil level gauge and the gas measuring element respectively, and stores the data in the data storage system, and the data in the data storage system It can be uploaded to the PC through the data transmission system, and can also be displayed through the data display system. The above-mentioned modules are powered by the power management module. The gas measuring element is installed inside the pipeline between the respirator and the explosion-proof pipe. The explosion-proof The pipe is connected to the oil level gauge, the oil level gauge is connected to the gas relay, and the gas relay is connected to the on-load voltage regulating body.

Abstract

The invention discloses a transformer and respirator online monitor and an operating method thereof. The transformer and respirator online monitor comprises a photoelectric speed sensor, a single-chip microcomputer acquiring system, a data storage system, a data transmission system and a PC (personal computer) which are sequentially connected. A data display system is serially connected between the data storage system and the PC. A power management module supplies power to various systems. The photoelectric speed sensor is installed in a pipe between a respirator and an anti-explosion pipe, the anti-explosion pipe is connected with an oil level meter connected with a gas relay, and the gas relay is connected with an on-load voltage regulator. The transformer and respirator online monitor has the advantages that relation between air flow in a respirator and fluctuated numerical values is displayed in real time, false oil level can be judged, and difficulty in daily maintenance is reduced.

Description

technical field [0001] The invention relates to an on-line monitoring instrument for a transformer respirator and a working method thereof. Background technique [0002] At present, there are a lot of research work on the online monitoring of transformers at home and abroad. The monitoring of respirator breathing conditions is blank, and the breathing conditions of respirators are judged entirely by personnel observation. When the normal temperature changes little, the breathing condition of the respirator is very weak. It is difficult to judge the breathing condition purely by personnel observation. Oil level, but can not judge whether the respirator is not breathing, it is likely to cause the failure to judge the normal operation of the transformer, so that the transformer defect cannot be found in time. This also increases the difficulty of daily maintenance of respirators. [0003] In the prior art, the defects of the automatic alarm device for transformer respirator a...
