Abstract

The invention discloses a method for changing the polarity of a generator excitation bus, which comprises the steps as follows: S101, dismounting the old DC excitation bus; S102, mounting a new DC excitation bus; S103, mounting the excitation bus in a cabinet; S104, testing the excitation bus. Compared with the best prior art, the method is simple in direction change and easy to operate, can satisfy the demand for the direction change of the excitation bus in a short time and has no special requirement on downtime of a unit; the direction change function of the excitation bus is provided with mutual latch-up, so that other abnormal conditions are not generated during the direction change process, and more importantly, the bottom of the bus extends downwards, and besides, other sizes are not changed, and the overall excitation bus keeps attractive.

Description

technical field [0001] The invention belongs to the technical field of generator manufacturing, and in particular relates to a method for changing the polarity of an excitation bus bar of a generator. Background technique [0002] Because the current passes through the contact surface of the carbon brush and the slip ring, and the direct conduction part is constantly changing, the current density is very high, which makes some points very high temperature; and due to the high temperature of the arc, the pole surfaces on both sides will be partially melted, If it falls off, the metal will turn into metal vapor, and the structure of the carbon brush will loosen and fall off due to oxidation and corrosion. This is the performance of electrical wear. However, the wear situation is different with different polarities. ) The surface is locally scorched and evaporates "metal vapor", which causes the surface of the anode to be damaged, which is called "anode evaporation"; the cathod...
