A method and device for early warning of abnormal operation of substation equipment

Abstract

The invention discloses an abnormal operation early warning apparatus of transformer substation equipment. The abnormal operation early warning apparatus comprises a transformer enclosure wall with the back surface connected with a back plate by virtue of a plurality of connecting pieces, the connecting pieces are connected with the back plate and / or the transformer enclosure wall by virtue of a guide plate arranged on the back surface of the transformer enclosure wall and / or on the front surface of the back plate, the back plate is connected with the transformer enclosure wall by virtue of the connecting pieces to form coolant clearances, and a plurality of temperature sensors and flow rate sensors are arranged on the surface of the back plate in the coolant clearances. For the traditional transformer structure form, the cooling mechanism is directly arranged on the transformer enclosure wall to directly cool the transformer, the cooling effect is guaranteed; the guide plate is arranged on the transformer enclosure wall, and a connecting hole is formed in the guide plate, so that no dead corner is guaranteed during the entire cooling process, the service life of the transformer is prolonged, the working efficiency of the transformer is guaranteed; only the back plate is provided with a plurality of sensors, the monitoring and early warning for the transformer can be realized; and moreover, the abnormal operation early warning apparatus is stable, reliable and worthy of being popularized and used.

Description

technical field [0001] The invention relates to the technical field of safe operation of substation equipment, in particular to an early warning method and device for abnormal operation of substation equipment. Background technique [0002] With the continuous development of society, people's demand for electricity is also increasing, especially in summer and winter during the peak period of electricity consumption every year, transformers are often overloaded, and most transformers generate a lot of heat due to overloading, which cannot be timely The leakage causes the transformer to stop working or the transformer is damaged, and even causes the transformer to explode, which not only seriously affects the production and life of the people, but also causes damage to the power equipment and causes losses to the country. The reasons are analyzed: [0003] When the transformer is running, the heat generated by the loss of the winding and core must be dissipated in time to avoi...

Problems solved by technology

However, because the device uses water as the medium, and the specific heat capacity of water is small, it is easy to cause excessive pressure due to boiling water, resulting in water leakage or air leakage, increasing potential safety hazards, and because it is not designed to deal with safety monitoring method, not only is not conducive to the stability of the transformer in the substation, but also increases the input of staff and equipment
