The jump heap threshold value of adjusting jumps heap alarm if so, lighting the jump heap alarm indicator of the tach signal processing module to check
Function；
When being switched to removal of load threshold testing state, detect whether current main pump revolving speed is more than that the removal of load threshold value adjusting is opened
Removal of load threshold value adjusted is closed, if so, the removal of load alarm indicator of the tach signal processing module is lighted, to check
Removal of load alarm function.
9. the detection method of nuclear power station main pump tach signal processing module as claimed in claim 4, which is characterized in that described three
The swept frequency range of the customizable modification of kind fixed frequency, the incremental frequency sweep mode and frequency sweep mode of successively decreasing is customizable to be modified.
10. a kind of detection method for realizing nuclear power station main pump tach signal processing module as described in any one of claim 1 to 9
System, which is characterized in that the system comprises:
Connection unit, for connecting power supply line and test wire jumper, to be connected to the self-test unit of tach signal processing module；And
Self-test unit realizes booting the instruction self-test, fixed rotating speed of the tach signal processing module for switching regulating switch
Self-test, frequency sweep mode self-test, channel self-test and threshold value self-test.
