Description
Technical field
It is a kind of diversification can be carried out by way of intelligent management specifically the present invention relates to a kind of transformer
The oil-filled transformer and its monitoring system and monitoring method of monitoring.
Background technology
Oil-filled transformer is that transformer core and winding are dipped in transformer oil, by transformer oil come cooler body
A kind of oil cooled transformer equipment.The device body of oil-filled transformer is built in fuel tank, the oil mass of fuel tank internal, temperature, wet
The many factors such as degree, air content can all impact to the state of iron core and winding.
In ongoing operations, in order to ensure safely and efficiently electricity consumption, extend the service life of oil-filled transformer, electric power work
Making personnel needs often detection oil-filled transformer, is worked with carrying out conventional maintenance management.Thus, oil-filled transformer is entered
Row walkaround inspection becomes a key job, and related operating personnel is also required to the record of progress related data making an inspection tour simultaneously.
In current concrete operations, the operational management of transformer is mainly or by artificial mode, and some are local, such as rural street
Road, the tour dynamics for transformer is not strong, and this maintenance management for transformer is unfavorable.
In this modern management society, our way to manage is also intended to intelligentized management mode step by step.
But in transformer industry, intelligentized management mode is also also in exploration and experimental stage, substantial amounts of popularization and application.
