Method and device for monitoring displacement of iron core in transformer

Abstract

The invention discloses a method and device for monitoring the displacement of an iron core in a transformer. The method comprises: receiving displacement information used for indicating the displacement degree of the iron core in the transformer and sent from a displacement sensor; receiving vibration information used for indicating the amplitude of the vibration of the transformer and sent from an impact recorder; and determining the actual displacement of the iron core in the transformer according to the displacement information and the vibration information and generating a determined result, wherein the determined result comprises that the iron core is displaced or the iron core is not displaced. The monitoring device is produced on the basis of the above method. The method and the device have advantages of reasonable design, convenient use, accurate monitored results, and low false alarm rate, save a plenty of maintenance cost for manufacturers, and achieve great economic benefit.

Description

technical field [0001] The invention relates to a transformer, and in particular provides a monitoring method and a monitoring device for iron core displacement in a transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. Usually, the transformer is transported to the construction site after it is assembled by the manufacturer. However, during the transportation, the transformer will be shocked and vibrated due to uneven road surface, undulating changes, engine vibration, bad tires, sudden braking, rear-end collision, etc., resulting in Different degrees of displacement of the iron core inside the transformer will bring major safety hazards to the transformer in the future operation. [0003] In the past, in order to monitor the displacement of the iron core inside the transformer, the vibration generated during the transp...
