The real-time monitoring system of the electrified detachable collector device of the generator

Abstract

The invention discloses a real-time monitoring system for an electrified detachable current collecting device of a generator. The real-time monitoring system comprises a brush box, a brush holder anda brush holder handle, wherein the brush holder handle is fixedly connected with the brush box; a carbon brush is arranged in the brush box; the real-time monitoring system is characterized in that atemperature sensor is arranged at the position, close to the carbon brush, on the brush box; a current sensor is arranged at a brush braid of the carbon brush; a wireless data processing device is arranged on the brush holder handle; the temperature sensor and the current sensor are connected with the wireless data processing device through data lines; and the wireless data processing device is connected with an external wireless data receiving device through a wireless signal. According to the real-time monitoring system for the electrified detachable current collecting device of the generator, fixation and removal are carried out by adopting a pure mechanical mode; the structure is more stable; the carbon brush is pushed by using a constant-pressure spring, so that the contact of the carbon brush and a collecting ring is better; and the real-time monitoring system also has the function of monitoring the temperature of the carbon brush and the current online.

Description

technical field

[0001] The invention relates to a generator equipment, in particular to a real-time monitoring system for a generator with electrified detachable current collector. Background technique

[0002] Existing brush holder assemblies mainly include ordinary brush holders and brush holders that can be detachable under charging. When the generator is running, the excitation current is transmitted to the brush holder through the conductive ring of the brush holder, and then transferred to the brush box, carbon brush, and finally to the generator collector ring through the brush holder. Since the collector ring of the generator is a high-speed rotating part and the brush holder assembly is a stationary part, the carbon brushes in the brush holder assembly are in contact with the surface of the collector ring, which causes friction and gradually wears the carbon brushes. After the carbon brush is worn to a certain extent, the carbon brush needs to be replaced. When us...
