A Transformer Core Group Used in Substations for Fast Assembling and Fixing

Abstract

The invention relates to the technical field of substations, and discloses a transformer core set for substations that can be fast assembled and fixed, including a base plate and a base plate that is movably overlapped on the base plate, and a groove is opened on the base plate, and the groove located in the base plate The top is fixed with a spring sleeve, and the upper part of the spring sleeve is plugged with an inverted T-shaped pressure bar. In the present invention, during the downward movement of the bottom plate, the two push rod pairs at the bottom of the bottom plate cooperate with the moving ports on the swing arm to squeeze the swing arm. At this time, the swing arm drives the side pillar to rotate through the second pin shaft. The three sets of arc-shaped clamps on the two side pillars are clamped and fixed on the iron core group to ensure the stability of the iron core group. The threaded screw is rotated through the first pin shaft and clamped on the other side pillar The rotating butterfly nut fits closely with the side struts in the clamping slots to ensure the stability of the two side struts, and the operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a transformer iron core set for substations that can be assembled and fixed quickly. Background technique [0002] At present, the power transformer is a kind of static electrical equipment, which is used to change the AC voltage of a certain value into another voltage with the same frequency or several voltages with different values. The alternating magnetic flux, through the magnetic conduction of the iron core, induces the AC electromotive force in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns, and its main function is to transmit electric energy. Therefore, the rated capacity is its main parameter, and the rated capacity is a customary expression of power. Value, which characterizes the size of the transmitte...

Problems solved by technology

The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns, and its main function is to transmit electric energy. Therefore, the rated capacity is its main parameter, and the rated capacity is a customary expression of power. Value, which characterizes the size of the transmitted electric energy, expressed in kVA or MVA, when the rated voltage is applied to the transformer, according to it to determine the rated current that does not exceed the temperature rise limit under specified conditions, the iron core of the power transformer is installed in an iron In the core barrel, there is an insulating layer between the iron core and the iron core barrel wall, but the electromotive force generated by the transformer iron core group that is quickly combined and fixed in the traditional substation will interfere with each other, affecting the normal use of the equipment, and the heat dissipation effect is poor, easy to Causes internal heat to be too high, causing the device to be easily damaged

[0004] The iron core group in the prior art needs to be assembled with steel plates and bolts step by step during the installation process, which not only takes time and effort, but also causes a waste of labor
