SVIT隔离车适用于在以空气为绝缘的户内可抽出式开关柜中，以供主回路无载荷换接、以及对被检修的主母线、断路器等电气设备与带电线路进行电气隔离之用。
将开关柜的上下触头直接相连，利用断路器形式的极柱和触头来连接隔离的母线可以避免受到环境的影响，非常安全和可靠。在进线/出线柜中它将主母线和馈线连接起来，在母联柜中，它连接了两段母线系统。
隔离车可以代替断路器使用在UniGear系列开关设备中，在发散式网络中完成进线/出线柜之间的连接，这种连接方式需采用双开关柜结构，每台开关柜均为母联形式，第一台配断路器，第二台配隔离车。

Five features of Industria1″ DCS system:
1. All-round integrated control system, integrating DCS & PLC & Field Bus;
2. Using RISC SuperScalar high-speed CPU, with super performance;
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
