Digital monitoring and protecting device for transformer

Abstract

The invention discloses a digital monitoring and protecting device for a transformer. The digital monitoring and protecting device is installed on the oil-immersed distribution transformer. The digital monitoring and protecting device comprises an oil level detection mechanism, an oil temperature detection mechanism, an oil pressure detection mechanism and a central control end, wherein the oil level detection mechanism is used for detecting the level of oil in the distribution transformer; the oil temperature detection mechanism is used for detecting temperature of the oil in the distributiontransformer; the oil pressure detection mechanism is used for detecting the pressure of the oil in the distribution transformer; the central control end is electrically connected with the oil level detection mechanism, the oil temperature detection mechanism and the oil pressure detection mechanism so as to collect and display the information of the oil level, the oil temperature and the oil pressure in the distribution transformer. According to the digital monitoring and protecting device, a traditional collection way is changed, and while the accuracy of a traditional monitoring signal of the distribution transformer is improved, the traditional monitoring signal is digitally displayed; all the adopted collection elements are traditional and common in the existing market, and the wholecost is little increased; during the big-data complete coverage period, the digital monitoring and protecting device can be matched with various output control modes at the same time, the practicability of the digital monitoring and protecting device in the future market is greatly improved, the device keeps pace with the times, and development of the period of big data is helped to be accelerated.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer digital monitoring and protection device. Background technique [0002] With the advent of the era of big data, the power industry has also set off an intelligent data cloud platform, including data collection, data analysis, fault alarm, fault protection actions, etc. The basic equipment support of this platform is to set up various equipment at the terminal, including transformers, especially the distribution transformers at the terminal. The number of distribution transformers is huge and the coverage is the widest. Therefore, digital monitoring and protection devices for transformers are designed. is imperative. [0003] Transformer digital monitoring and protection device refers to that some information of the transformer is collected by sensor elements and then transmitted to the integrated device, displayed and recorded in digital form, and ...

Problems solved by technology

[0007] For pressure, there is only a release valve on the top of the oil level pipe. The valve is a pressing structure. When the pressure exceeds the force of the pressing, the valve opens to release the pressure. It is only a mechanical protection and cannot display the pressure value, let alone monitor the pressure. changes, releases, etc.
