Problems solved by technology

[0002] The leakage of the rotor of the double-water internal cooling generator is one of the main reasons that endanger the safe operation of the generator. During the operation of the unit, if it is not found in time, it will be shut down and dealt with, which will delay the repair time of the equipment, and it will be one of the most serious failures of the thermal power unit. , it will cause the unit to stop running, and it will cause damage to the main engine, burn the winding or iron core, and damage the main shaft.

Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The technical problem to be solved by the present invention is: how to use the limited field conditions to carry out rapid diagnosis.

[0030] After repeated research, this application can classify the leakage of the double-water internal cooling generator set into three types: generator stator, generator rotor, and generator air cooler. The causes of the three types are different, and the methods to eliminate them are also different.

[0031] How to quickly distinguish and judge whether the water leakage of the generator or the cooling water pipe of the air cooler is leaking at the site, especially under the operating conditions, is very important, and it also points out the direction for the next correct treatment, espec...

Abstract

The invention provides a double water internal cooling generator water leakage detection method and a double water internal cooling generator water leakage detection system. The double water internalcooling generator water leakage detection method comprises the following steps of: testing accumulated water at the bottom part of a double water internal cooling generator; if the accumulated water is judged to be soft water according to a test result of the accumulated water, judging that a generator leaks water; and if the accumulated water is judged to be hard water, judging that an air coolerleaks water, so that whether the generator or a cooling water pipe of the air cooler leaks can be quickly and preliminarily judged. In addition, whether a stator or a rotor of the generator leaks water can be further judged by checking whether the water leakage form of the generator is water dripping or mist.

Description

technical field [0001] The invention relates to a method and system for detecting water leakage of a double-water internal cooling generator. Background technique [0002] The leakage of the rotor of the double-water internal cooling generator is one of the main reasons that endanger the safe operation of the generator. During the operation of the unit, if it is not found in time, it will be shut down and dealt with, which will delay the repair time of the equipment, and it will be one of the most serious failures of the thermal power unit. If it is light, it will cause the unit to stop running, and if it is serious, it will cause damage to the main engine, burn the winding or iron core, and damage the large shaft. Contents of the invention [0003] The object of the present invention is to provide a method and system for detecting water leakage of a double-water internally cooled generator. [0004] In order to solve the above problems, the present invention provides a w...
