Problems solved by technology

However, if the resistance value of the resistors connected in parallel is too small, the normal operation of the power system will be affected on the PT opening triangle, and in severe cases, the PT will be burned; in addition, because the frequency of ferromagnetic resonance is often not single, this method is It is difficult to eliminate the resonance of all frequencies; finally, the resonance elimination device in the prior art cannot realize the memory and collection of data

Abstract

The invention discloses a data acquisition module of a resonance elimination device. The data acquisition module comprises an insulating tube, wherein the top end of the insulating tube is provided with an upper aluminum cover; the bottom end of the insulating tube is provided with a lower aluminum cover; an aluminum electric connector is also arranged on the upper aluminum cover; the insulating tube is provided with an insulating sleeve; the resonance elimination device is arranged on the inner side wall of the insulating tube; a data acquisition system is arranged at the central position inthe insulating tube; and a sensor interface in contact with the data acquisition system is arranged on the outer side surface of the data acquisition system. The data acquisition module is simple in structure and convenient to use, frequency resonance can be relatively well eliminated, data acquisition and analysis of the frequency resonance are achieved and the actual operating requirements are met.

Description

technical field [0001] The invention relates to a data acquisition module of a harmonic elimination device, belonging to the technical field of harmonic elimination devices and data acquisition. Background technique [0002] The non-linear resistance harmonic elimination arrester (referred to as the harmonic elimination device) is a non-linear resistance harmonic elimination lightning arrester installed between the neutral point of the electric locomotive transformer and the ground. It is a high-capacity non-linear resistor that can play The function of damping and current limiting can play a good role in limiting the ferromagnetic resonance of voltage transformers. In the power system, due to the matching of the nonlinear inductance of the voltage transformer and the capacitance of the line to the ground, the ferromagnetic resonance overvoltage is caused, which directly threatens the safe operation of the power system. In severe cases, it will cause the explosion of the PT ...
