Embodiment 1

[0019] A generator failure detection method, characterized in that, comprising the following steps:

[0020] (1) Start the generator, detect whether the generator continues to run within the first predetermined time, if so, end; if otherwise, perform step (2);

[0021] (2) Determine the cause of the startup failure, and take measures according to the reason.

[0022] Described step (2) specifically comprises the following steps:

[0023] a. Judging whether the DC oil injection pump can be started and whether the DC oil injection pump can be stopped, if so, go to step d; otherwise, go to step b;

[0024] b. Detect whether the fuse is disconnected, if yes, switch the spare fuse, and end; otherwise, go to step c;

[0025] c. Detect the voltage difference between the two ends of the contactor auxiliary contact, judge whether the voltage difference is greater than the preset first voltage, if so, switch the backup contactor, and end; otherwise, go to step d;

[0026] d. Judging ...

Abstract

The invention discloses a method for detecting a generator startup failure. The method comprises: (1) startup the generator to detect whether the generator is continuously running during a first preset time, and if yes, ending; if no, performing step (2); (2) determining the reason of the startup failure, and making a treating measure according to the reason. The method for detecting the generatorstartup failure can monitor the startup condition of the generator in real time, and automatically analyzes the reason immediately when the startup failure occurs, and provides a solution in timely and rapidly, thereby ensuring the reliability of the power supply to the greatest extent.

Description

technical field [0001] The invention relates to the field of generators, in particular to a method for detecting failure to start a generator. Background technique [0002] Electricity is an indispensable basis for industrial production and people's daily life. Therefore, the safe and stable operation of generators is the prerequisite for ensuring electric power. However, due to the large number of electric parts in the generator, the generator cannot be started normally due to the problems of the parts themselves and the cooperation between them. [0003] In the prior art, although there is an alarm for generator startup failure, there is no effective detection method for startup failure. Contents of the invention [0004] Therefore, in view of the above-mentioned problems, the present invention provides a kind of generator start failure detection method, it is characterized in that, comprises the following steps: [0005] (1) Start the generator, detect whether the gen...
