Distribution transformer supervision system

Abstract

The invention discloses a distribution transformer supervision system, which comprises a distribution transformer body, a label writing unit for testing the distribution transformer body, a direct-current resistance transformation ratio testing unit, a performance testing unit and a partial discharge testing unit, and is characterized in that monitoring photographing equipment is arranged in each of the label writing unit, the direct-current resistance transformation ratio testing unit, the performance testing unit and the partial discharge testing unit; according to the scheme, the NFC label is additionally arranged on the surface of the distribution transformer body, and the NFC label is scanned through a mobile phone or special scanning equipment, so that a manufacturer, logistics information, an experiment report, an experiment record and a picture of each detection link of the distribution transformer body can be inquired at any time; the production, detection, sales, warehousing, ex-warehouse, logistics and other links of the distribution transformer body are all monitored and managed, so that the phenomena of production with a label, counterfeiting of an experimental report and the like can be fundamentally avoided, the sampling inspection number of the transformer can be reduced by the state grid company, and the purposes of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention relates to the field of distribution transformers, more specifically, to a distribution transformer supervision system. Background technique [0002] At present, there are some problems in the distribution transformer market. For example, in order to win the bid at the lowest price in the bidding of the State Grid, transformer manufacturers outsource production orders to small enterprises for OEM production in order to reduce production costs, resulting in poor performance and quality of distribution transformers. There is no guarantee; because the State Grid Corporation does not trust the quality of the products, it can only adopt the method of increasing the intensity of random inspections, thus wasting a lot of manpower and material resources. [0003] At the same time, the entry threshold of the distribution transformer market is relatively low, the third-party testing industry market is chaotic, and the authenticity of the test equip...

Problems solved by technology

[0002] At present, there are some problems in the distribution transformer market. For example, in order to win the bid at the lowest price in the bidding of the State Grid, transformer manufacturers outsource production orders to small enterprises for OEM production in order to reduce production costs, resulting in poor performance and quality of distribution transformers. There is no guarantee; the State Grid Corporation also has no choice but to increase the intensity of random inspections because of distrust of the quality of the products, thus wasting a lot of manpower and material resources

[0003] At the same time, the entry threshold of the distribution transformer market is relatively low, the third-party testing industry market is chaotic, and the authenticity of the test equipment inspection report and transformer type report cannot be guaranteed, which affects the fair competition among transformer manufacturers and is not conducive to the healthy development of the industry. Long-term development
