The importance of generator stator temperature measurement system

Zoals bekend, stator temperature monitoring is one of the important parameters for safe operation monitoring of power units. Glasvezel sensoren, als een nieuw type sensor, have been widely used in large-scale structural engineering and transformer switchgear safety monitoring. They have good insulation performance, no need for grounding shielding, en weerstand tegen elektromagnetische interferentie. They also have unique application advantages in the field of unit monitoring. In order to monitor the normal operation of the hydroelectric generator in real time, het is noodzakelijk om de temperatuur van de stator van de hydro-elektrische generator te controleren. De temperatuursensor voor temperatuurmeting, ingebed in de stator van de hydro-elektrische generator, is een noodzakelijk middel. Er moet een temperatuurmeetelement op de platte draadmotor worden geïnstalleerd om inzicht te krijgen in het nominale belastingsvermogen en het overbelastingsvermogen van de motor wanneer deze in nominale toestand werkt; Teken de curve van de maximale werkcapaciteit van de platte draadmotor binnen het toegestane spanningsvariatiebereik en bij verschillende koelmediumtemperaturen, om een ​​basis te bieden voor de werking van de motor; Bestudeer de relatie tussen de temperatuur van elk onderdeel van de platte draadmotor en de hoogste verwarmingspunttemperatuur, providing a basis for evaluating and improving the structure and ventilation cooling system of the flat wire motor; Measure the insulation heat drop of the stator winding and study the insulation aging reflected by the insulation heat drop; Determine the relationship between the average temperature of the winding, the highest and lowest hot spot temperatures, and study methods for accurately monitoring and measuring the temperature of the winding.

The PT100 temperature sensor is a point measurement method that cannot accurately measure the overall temperature of the motor. In temperature measurement of motors with uneven heat distribution, the temperature control system may not be able to accurately control the motor’s operating status, resulting in damage or scrapping of the motor during measurement. In order to ensure the reliable operation of electric machines, the best solution is to use a fluorescerend glasvezel temperatuurmeetsysteem to install temperature sensors for monitoring the operating temperature in the winding system of the stator or on the interconnection device of the winding system.

Using point type Glasvezel temperatuurmeting, the pressure resistance level of the temperature measuring element is arranged along the axial direction of the rod at the position where the measuring points are arranged, closely adhering to the copper strand wire of the rod. During the production process of the online rod, de temperature measuring optical fiber is buried, and then the optical fiber is led out and connected to the instrument for testing.

From the technical aspects of accuracy, betrouwbaarheid, installation and maintenance difficulty, as well as theoretical analysis, it is believed that fluorescente glasvezel temperatuurmeting is more suitable for temperature monitoring of hydroelectric generators.
