Abstract

The invention provides a temperature monitoring system, comprising a measurement module, a reading module and a receiving processing module. The measurement module, the reading module and the receiving processing module are connected in sequence. The measurement module is connected with the reading module through utilization of a lead wire. The receiving processing module is connected with a terminal. The measurement module is equipped with a measurement assembly. The measurement assembly is fixed on a measurement target. According to the system, temperature of each monitoring point of rotor magnetic yokes in a hot padding process can be rapidly and effectively detected, whether all heating plates are in heating states or not can be rapidly and effectively detected, monitoring measurementefficiency can be greatly improved, and hot padding mounting quality of the rotor magnetic yokes can be ensured.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a temperature monitoring system and a heating pad process. Background technique [0002] The yoke is an integral part of the magnetic circuit of the generator motor, and it is also a structural part of the fixed magnetic pole; the yoke can be divided into fan-shaped laminated yoke and thick ring plate yoke according to the composition form; according to the cooperation between the yoke and the rotor bracket (main shaft) According to the form, it can be divided into shrink-fit yoke and floating yoke. [0003] The rotor yoke is subjected to centrifugal force during operation, and radial deformation will occur. The shrink-fit yoke means that the yoke is heated to expand it, and a gap is created between the main key of the rotor bracket and the yoke, and a gasket is added to the gap. After cooling down, the yoke shrinks and forms an interference that will make the magnet The yoke form...
