Detailed description of the invention
In order to the technical characteristic of the present invention, purpose and effect are more clearly understood from, now compare accompanying drawing
Describe the detailed description of the invention of the present invention in detail.
As it is shown in figure 1, be an enforcement of nuclear power plant reactor of the present invention protection system test analog systems
Example, including actuator drivers 11, simulates normally closed drive circuit 12, test bypass circuit 13, test
Result display circuit 14 and power supply 15.This power supply 15 is actuator drivers 11, it is normally closed to simulate
Drive circuit 12, test bypass circuit 13 and test result display circuit 14 are powered.Particularly, power supply
15 power for actuator drivers 11 by simulating normally closed drive circuit 12, thus keep actuator
Driver 11 is in power supply state.It should be understood that this actuator drivers 11 can be execution machine
Structure drives relay, is powered by maintenance, it is ensured that actuator drives relay to be in obtain electricity condition, keeps away
Exempt from the misoperation in downstream.
This test bypass circuit 13 includes test switch.The normally closed driving of simulation is cut off by triggering test switch
Circuit 12 drives the power supply of relay for actuator；And power supply 15 by test bypass circuit 13 is
Actuator drives relay to power, and is powered for test result display circuit 14 by power supply 15, passes through
The power failure state of normally closed drive circuit 12 is simulated in test result display circuit 14 display.
Please referring back to Fig. 2, it is an enforcement of nuclear power plant reactor of the present invention protection system test analog systems

As in figure 2 it is shown, actuator drives relay to be chronically at electriferous state.Normal operation
Under, the 48V DC source of nuclear safety system or equipment passes through the second resistance R2 and normally closed output relay UR
Normally closed contact to actuator drive relay XR power, ammeter branch road and the first resistance R1 in parallel
Branch road is all off.When safety signal arrives, normally closed output relay UR excitation, normally closed contact breaks
Opening, corresponding actuator drives relay XR loss of excitation, and actuator is by action.When test switch CC closes
Close, when stimulus injects, the normally closed same excitation of output relay UR, normally closed contact disconnects, but 48V
DC source the first resistance R1 in parallel props up road direction actuator and drives relay XR to power, it is ensured that right
Answering actuator to drive relay XR also at excited state, actuator keeps original state to be failure to actuate.This
Time, ammeter MA loop connects but is designated as zero, represent normally closed output relay UR excitation, normally closed connects
Point disconnects, and safety signal action is normal.But during this time, if set state really changes, need
Corresponding test execution mechanism action, and actuator is akinesia, because the first resistance of parallel connection
Safety signal is masked by R1 branch road, is greatly improved test putting forward nuclear safety level to unit
Rise.
