Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] In order to solve the problem that in existing nuclear power plants, when a unit or an adjacent unit is shut down, the steam converter cannot generate steam, and auxiliary steam needs to be produced through an auxiliary boiler system, which increases costs, and the auxiliary steam systems of different nuclear power plants on the same base cannot be shared, resulting in waste of resources, the utility model provides a set of auxiliary steam networked pipeline system, which is suitable for different nuclear power plants on the same base, and the auxiliary steam distribution systems of two different nuclear power plants on the same base can be used as backup for each other, which can reduce costs and avoid waste of resources.
[0039] Figure 1 A structural diagram of an auxiliary steam networking pipeline system according to an embodiment of the present invention is shown.
[0040] Specifically, Figure 1 As shown, the auxiliary steam networked pipeline system includes: a networked pipeline 100 arranged between the first nuclear power plant and the second nuclear power plant for transmitting auxiliary steam, a first pipeline network monitoring system arranged on one side of the first nuclear power plant, and a second pipeline network monitoring system arranged on one side of the second nuclear power plant.
[0041] The first pipe network monitoring system includes: a first parameter monitoring module 105 , a first control switch 101 and a first control module 107 ; the second pipe network monitoring system includes: a second parameter monitoring module 205 , a second control switch 201 and a second control module 207 .
[0042] In this embodiment, the first parameter monitoring module 105 is set on the networked pipeline 100, and is used to monitor the parameters of the auxiliary steam supplied from the first nuclear power plant to the second nuclear power plant and collect the parameters to obtain the first monitoring parameters. Optionally, in this embodiment, the first parameter monitoring module 105 includes: a first pressure monitoring unit; the first monitoring parameter includes: a first pressure monitoring signal. Among them, the first pressure monitoring unit is connected to the first control module 107, and is used to monitor the pressure of the networked pipeline 100 for supplying auxiliary steam from the first nuclear power plant to the second nuclear power plant, and generate a first pressure monitoring signal according to the pressure of the networked pipeline 100, and send the first pressure monitoring signal to the first control module 107.
[0043] In this embodiment, the first control switch 101 is provided on the networked pipeline 100, and is used to be opened or closed according to the first switch control signal output by the first control module 107. Specifically, when the first switch control signal is an open signal, the first control switch 101 is opened; when the first switch control signal is an off signal, the first control switch 101 is closed. Optionally, in the embodiment of the utility model, the first control switch 101 can be an electric isolation valve.
[0044] In this embodiment, the first control module 107 is connected to the first parameter monitoring module 105 and the first control switch 101 respectively, and is used to output a first switch control signal according to the first monitoring parameter. Optionally, the first control module 107 can be a control chip, such as the first control module 107 can use an existing conventional single-chip microcomputer. It should be noted that the present utility model only uses the existing functions of the single-chip microcomputer and does not improve its program.
[0045] Specifically, the first pressure monitoring unit can be a pressure set value sensor. The first pressure monitoring signal output by the pressure set value sensor is a logic signal of 0 or 1. By setting the pressure set value sensor, when the first nuclear power plant transmits auxiliary steam to the second nuclear power plant through the networked pipeline 100, the pressure set value sensor can monitor the pressure of the networked pipeline 100; when the pressure in the networked pipeline 100 is greater than the pressure set value, the first pressure monitoring signal output by the pressure set value sensor is 0; when the pressure in the networked pipeline 100 reaches the pressure set value, the first pressure monitoring signal output by the pressure set value sensor changes from 0 to 1. Therefore, when the first control module 107 receives the first pressure monitoring signal output by the pressure set value sensor changes from 0 to 1, it outputs a close signal, and at this time, the first control switch 101 is closed. The pressure of the networked pipeline 100 is monitored by the pressure set value sensor. When a sudden drop in the pressure of the networked pipeline 100 is detected, it is considered that the system may have problems such as leakage or pipe breakage. At this time, the first control module 107 outputs a close signal to control the first control switch 101 to close, which can avoid the impact on another nuclear power plant. It should be noted that, in the embodiment of the utility model, the control process of the first control module 107 on the first control switch 101 can refer to the prior art, for example, can refer to the existing patent document (201610246138.9).

By setting the first flow monitoring analog sensor 102, remote monitoring of the flow in the networked pipeline 100 can be achieved. Among them, the first steam flow data is the real-time flow measurement value of the networked pipeline 100.

[0053] In this embodiment, the second control switch 201 is provided on the networked pipeline 100, and is used to be opened or closed according to the second switch control signal output by the second control module 207.

It should be noted that the utility model only uses the existing functions of the single-chip microcomputer and does not improve its program.
[0055] Specifically, the second pressure monitoring unit can be a pressure set value sensor. The second pressure monitoring signal output by the pressure set value sensor is a logic signal of 0 or 1. By setting the pressure set value sensor, when the second nuclear power plant transmits auxiliary steam to the first nuclear power plant through the networked pipeline 100, the pressure set value sensor can monitor the pressure of the networked pipeline 100; when the pressure in the networked pipeline 100 is greater than the pressure set value, the second pressure monitoring signal output by the pressure set value sensor is 0; when the pressure in the networked pipeline 100 reaches the pressure set value, the second pressure monitoring signal output by the pressure set value sensor changes from 0 to 1. Therefore, when the second control module 207 receives the second pressure monitoring signal output by the pressure set value sensor changes from 0 to 1, it outputs a close signal, and at this time, the second control switch 201 is closed. The pressure of the networked pipeline 100 is monitored by the pressure set value sensor. When a sudden drop in the pressure of the networked pipeline 100 is detected, it is considered that the system may have problems such as leakage or pipe breakage. At this time, the second control module 207 outputs a close signal to control the second control switch 201 to close, which can avoid the impact on another nuclear power plant. It should be noted that, in the embodiment of the utility model, the control process of the second control module 207 on the second control switch 201 can refer to the prior art, for example, can refer to the existing patent document (201610246138.9).
