Description
Technical field
The present invention relates to electrical generator fields, especially a kind of generator fan failure automatic detection method.
Background technique
Since large-scale generator can generate biggish heat at work, as sharply increasing for heat may result in electricity
Therefore the damage of power component or even the collapse of generator are commonly used blower in the prior art and are come to generator heat-radiation.
But in practical applications, it often will appear the case where blower irregular operating.Maintenance personnel is usually required to enter
High-risk scene checks that this process wastes time also not can guarantee the correct of result.
Summary of the invention
Therefore, in view of the above-mentioned problems, the present invention provides a kind of generator fan failure automatic detection method, feature exists
In, comprising the following steps:
(1) microseismic detection device real-time detection on generator housing is set with the presence or absence of vibration, if there is executing step
Suddenly (2) execute step (1) if there is no circulation；
(2) the microseismic detection device detects that vibration, output enabled instruction are located at the generator body to connected to it
Wind speed measuring device on body；
(3) wind speed measuring device measures real-time wind speed V, if the wind speed V is less than default wind speed threshold value, exports wind
Machine faulting instruction is to master controller；
(4) master controller judges fan trouble type after receiving the fan trouble instruction.
The step (4) specifically comprises the following steps:
A. the protecting circuit in the primary power source circuit of blower described in the main controller controls realizes self-test, if from
Inspection fault-free thens follow the steps e；If self-test is faulty to then follow the steps b；
B. the spare test loop of the main controller controls work so that test fan power insurance whether tripping, if
It is then to determine the fan trouble type for insurance damage；If not, thening follow the steps c；
C. the master controller receives the blower three phase isolated resistance and D.C. resistance resistance value of measurement, described in judgement
Resistance value whether in the reasonable scope, if it is, determining that the fan trouble type is line short；If it is not, then executing step
Rapid d；
D. the master controller receives the voltage difference at each connecting terminal both ends in the blower power circuit of measurement, judgement
Whether the voltage difference is greater than default first voltage numerical value, if it is, determining the fan trouble type for wiring disconnection；Such as
Fruit is no, then alarms, and terminates；
E. the master controller receives the voltage difference at each contactor both ends in the blower power circuit of measurement, judges institute
State whether voltage difference is less than default second voltage numerical value, if it is, determine that the fan trouble type is abnormal for control, if
It is no, then follow the steps f；
F. the master controller receives the motor temperature numerical value of measurement, and detects motor temperature protection act situation, if
The temperature is less than the first temperature threshold, but motor temperature protection has acted, then determines that the fan trouble type is
Temperature protection malfunction；Otherwise, step g is executed；
G. the master controller detects whether persistently to receive the enabled instruction transmitted, if otherwise determining the wind
Machine fault type is communication failure；If it is, terminating.
The present invention is first checked incidental failure by the way that accurately detection ordering and step is arranged, it is not easy to
The failure of generation not only makes the investigation of failure more fully in rear investigation, but also greatly improves the efficiency of malfunction elimination,
Reduce the operating time.
