I&C interface 仪表和控制接口
Mechanical Sketches 机械示意图
The sketches shall show the principal systems where mechanical interfaces exist and show any exceptions to general rules of limits of supply.
该示意图应显示其中存在机械接口的主要系统，并应显示任何有关供货范围总则的例外事项。
All the T&G Package related systems’ mechanical sketches shall be drawn up by T&G Package Bidder during the bidding process according to the following sharing and the information given in this BIS Part 5 Chapter 2.
所有与“T&G包”相关的系统的机械示意图均应由“T&G包投标方”在投标过程中根据下列共享信息和本BIS中第5部分第二章中给出的信息绘制。
The specimen of typical interface identification drawing is shown in Fig M1. This drawing shows the style only.
图M1给出了典型接口标识图的样本。该图仅示出了其样式。
Mechanical Interfaces are schematically indicated in such drawings, while detailed interfaces shall be developed in arrangement layout drawings. All the individual detailed interface information shall be exchanged via interface exchange documents in order to carry out the design and layout.
在这些图纸中仅简要显示了机械接口，而详细的接口应在设备布置图中给出。所有各种接口的详细信息均应通过接口交流文件进行交流，以便进行设计和布置。
NI Supplier shall be responsible for the Plant-wide I&C supply, engineering and design within his scope, including Main Control Room& Other Control Rooms/Area. T&G Supplier shall be responsible for the design and supply of the T&G control and protection systems (detail description refer to section 2.2.1.5 Chapter 2 of Part 5). T&G Supplier shall provide the requirements of control, display, alarm and record of their systems in Main Control Room to NI supplier.
“NI供方”应负责全厂范围I&C供货，其供货范围内的工程设计，包括“主控制室”和“其它控制室/区域”。“T&G供方”应负责T&G控制和保护系统的设计和供货（详细说明参见第5部分第2章的第2.2.1.5节）。“T&G供方”应向NI供方提供“主控制室”中其供货系统的控制、显示、报警和记录的要求。
4.3.2. NI Supplier shall provide interface modules for interfacing with NI (special systems), CI (mainly T&G and related systems) and BOP systems. I&C Supplier shall coordinate with NI&CI designers to determine the quantities and allocation of interface modules for its adequacy and complete the integrated system design. Finally NI supplier should ensure the completeness and correctness for integrated I&C.
“NI供方”应提供用于与NI（专用系统）、CI（主要为T&G和相关系统）和BOP系统进行界面连接的接口模块。“I&C供方”应与NI和CI设计方进行协调，以确定接口模块适当的数量和配置，并完成一体化系统设计。最后，NI供方应确保一体化I&C系统的完整性和正确性。
4.3.3. The limit of supply, both for Level 1 and Level 2 and for Level 0 and Level 1, is at input terminal strips of interface modules supplied by NI supplier. Some vital and significant safety commands, such as turbine trip, shall be hard-wire connected directly from Main Control Room (MCR) to Level 0, the interface is at the input terminal strips of the MCR.
第1层和第2层以及第0层和第1层的供货范围以NI供方提供的接口模块的输入端子板为界。有些关键且意义重大的安全命令，如汽轮机跳闸，应直接从“主控制室（MCR）”硬线连接到第0层，接口在主控制室的输入端子板处。
4.3.4. Whether the interfaces among NI, BCI and T&G are detailed and clarified or not is one of the key factors in accomplishing the project smoothly. Therefore, T&G Supplier shall divide and clarify the interfaces with I&C supplier as detail and clear as possible. Besides written explanations, detailed interface diagrams should also be attached.
NI、BCI和T&G之间的接口是否详细和清楚是顺利完成项目的关键因素之一。因此，“T&G供方”应与I&C供方划分并尽可能详细和清楚地说明接口信息。除书面说明之外，还应附上详细的接口图。
