Research On 110kV And Below Transformer On-site Calibration Institutional Operation Vehicle

Transformer is widely used by the power plant and power grid, power and power supply company, power supply companies and users of the settlement, which as part of the electric energy metering device, played a very important role. High voltage transformer and large current transformer belongs to the installation of equipment, it must be calibration on-site. Because of the high voltage and distribution environment, puts forward the acid test to the safety of the verification and the handling workload of the verification equipment. Therefore, developed a integrated type transformer metrological and calibration vehicle on-site is quite necessary.Many unsafe factors and the heavy workload were existed about calibration of transformer on-site, comprehensive compared several methods the calibration of the transformer on-site, the transformer metrological and calibration vehicle on-site was introduce in this paper. It is a vehicle for the carrier, digital processor was used the central control management unit, through professional vehicle modified, and advanced testing equipment constitutes flow of metrological calibration lab.The author participated in the whole process of development, which include the project research, design, installation and debugging. The project approved by zhejiang sci-tech novelty search Advisory Association testing and got appraisal committee experts praise, it says that the comprehensive technology of the project is a domestic leading level, has broad application prospect.
