Intelligent distribution transformer integrated test and fault determination test handcart

Abstract

The invention discloses an intelligent distribution transformer integrated test and fault determination test handcart. The handcart comprises a housing, wheels and a handle, wherein the housing is an anti-high-magnetic-interference housing, the housing is internally provided with an integrated controller, an integrated wiring unit, an environment control detection unit and a safety control protection unit, the integrated controller is respectively connected with the environment control detection unit, the safety control protection unit and the integrated wiring unit and is connected with a central control PC, and each external-end wiring port of the integrated wiring unit is arranged at the side wall of the housing. The intelligent distribution transformer integrated test and fault determination test handcart realizes a modular design and greatly reduces the test time and the labor cost; and concentrated and simple equipment control is realized, a power equipment preventative test management system is designed, completed and configured, and unified data management and diagnosis analysis are also realized.

Description

technical field [0001] The invention relates to the technical field of transformer intelligent testing, in particular to an intelligent distribution transformer comprehensive test and fault discrimination test trolley, which is suitable for routine tests of 10kV and above voltage distribution transformers and electrical main equipment, and fault cause discrimination of faulty transformers and comprehensive diagnosis. technical background [0002] At present, in the power systems of some relatively developed countries in foreign countries, most of the transformer tests use the power test platform. In the domestic power system, only some test instruments with single test items and simple functions are used, such as power cable withstand voltage testers. Or simply fix the test instruments on the vehicle to form a mobile high-voltage test room. It can be considered that portable hand-push distribution transformer comprehensive test and fault discrimination test equipment that ...

Problems solved by technology

[0005] In view of the large number of distribution network transformers, the difficulty of detection and the impact on the reliability of power supply, and the heavy test work, it is proposed to use a trolley-type distribution transformer comprehensive test and fault diagnosis comprehensive test device for the operation of the distribution network transformer and the test requirements at different stages. In this way, the efficiency, level and quality of the electrical test can be comprehensively improved, the heavy workload of instrument handling during the test can be reduced, and the flexibility and mobility of the on-site test work can be improved. It can accurately judge whether the working status of the equipment is normal, discover equipment defects and hidden dangers in time, greatly improve the reliability of transformer operation and the level of technical management, and provide a basis for realizing the status detection of equipment
