Problems solved by technology

The working status of the transformer often changes due to different working conditions and tasks, but there is no transformer monitoring equipment installed on the ship at present, which is not conducive to centralized control of the working status of the transformer, which is inconsistent with the current development requirements of informatization and automation. adapt to
At the same time, so many transformers have a heavy workload in daily inspection and maintenance, and it is difficult to find out in time when a fault occurs

Abstract

The invention discloses a method for monitoring a low-voltage distribution transformer for ship. The method comprises: electrical parameters of a primary side and a secondary side of a transformer are collected and on-line detection is carried out on a transformer winding temperature; according to the data, more operating parameters are calculated; the operating parameters are compared with a preset value; and when the operating parameters are lower than or higher than the preset value, the transformer is determined to be abnormal and then warning is carried out. In addition, the invention also provides an apparatus for monitoring a low-voltage distribution transformer for ship. Using the method and apparatus, electrical parameter detection of the primary side and the secondary side of the transformer and on-line detection of the transformer winding temperature can be realized.

Description

technical field [0001] The invention belongs to the field of ship power systems, and in particular relates to a monitoring method and device for a low-voltage distribution transformer used in ships. Background technique [0002] On a ship, it is usually necessary to configure a large number of transformers to convert the power generated by the power generation equipment into an electrical system suitable for each electrical device. Generally, a relatively large ship may need to be equipped with hundreds of transformers. The working status of the transformer often changes due to different working conditions and tasks, but there is no transformer monitoring equipment installed on the ship at present, which is not conducive to centralized control of the working status of the transformer, which is inconsistent with the current development requirements of informatization and automation. adapt. At the same time, so many transformers have a heavy workload in daily inspection and m...
