1 COMBIFLEX Mounting and Engineering System for Relay and Control Panels.
2 A building system offering well-engineered flexibility and high performance Build in the protection and security you need The COMBIFLEX mounting and engineering system is a complete concept for engineering of relay and control panels. Based upon this concept, complete panels can easily be built. COMBIFLEX components can provide simple custom logic circuits via auxiliary relays, timers and standard functions. Measuring relays e. g. for currents and voltage provide simple and fast system solutions. In addition, some of the special measuring relays available offer characteristics not available with standard protection terminals. All our products, however, have the advantage of being designed and developed specifically for integration with the COMBIFLEX mounting and engineering system. The COMBIFLEX system offers several advantages. Flexibility Standard mechanical dimensions and connection patterns. Availibility of all standard relay functions. Comfort Connections are based on terminal pins and sockets with ready made conductors. Simple transfer connection Two conductors can be connected to virtually all electrical points, making connection simplicity itself. Personal safety All connection point are insulated for human contact and all routine tests can be made while system is in service and energized, and without changing any connections. COMBIFLEX products The revitalised range covers a wide spectrum of products from measuring relays and time, auxiliary and bistable relays to relay assemblies dimensioned to meet forthcoming engineering requirements in power systems and industrial applications. The full range of new relays is presented on the pages 5-7 of this brochure, and the range of available relays is shown in the Byuer s Guide catalogue. Combitest relay test system Even though modern microprocessor equipment has built-in self-test and monitoring functions, it can be necessary to use an injection test facility. This ensures that all parts of the final assembly and overall system work exactly as intended. The secondary injection test facility can also be used to enable the relay system to receive a simulated or recorded power system event in play-back mode. This permits testing of cases which may have caused confusion or concern in relay operation or lack of operation. Numerical play-back is further facilitated using test system simulation software. 2 ABB Automation
3 Mounting and Engineering System with overall coordination and integration With the introduction of the 500-series protection, monitoring and control equipment, each protection system offers a wide range of internal flexibility. By utilising various combinations of additional COMBIFLEX modular options the same basic product can be used in a wide variety of applications, mounted in 9" racks, panels or walls. be used stand alone in the form of measuring relays for different applications, separate logic circuits as well as comprehensive protective assemblies for a variety of protection purposes. COMBIFLEX is also compatible with components used for testing, connection and designation purposes. COMBIFLEX environment The 500-series represents terminals for line distance, differential, transformer protection as well as bay lever control. These protection terminals are often integrated with separate relays for backup measurement, trip functions or contact replication. The terminals combine easily with COMBIFLEX auxiliary equipment such as test switches, auxiliary tripping relays, lock-out relays and other units in the design of complete protection and control cubicles. The COMBIFLEX range covers products which may A part of the ABB SA Concept The COMBIFLEX system is built for the future: new technology provides new and additional functionality and complements the other microprocessor protective relay and control equipment families, for example the 500-series. The COMBIFLEX system is an integrated part of the overall ABB SA concept for integrated ITsolutions for the power industry. The reliability of the COMBIFLEX system is documented through 25 years of use in many different environments, including nuclear power applications. New Compact Line Protection and Breaker Failure Relays The RAHx/RXHx 4xx-series of numerical products are intended for general power system applications and as back-up to 500-series terminals for all system voltage levels including EHV. The relays are also suitable for retrofit of installations using static or electromechanical designs. Several mounting alternatives are available; 9" racks, panel mounting cases and DIN-rail adapters. Ease of handling is an added benefit as well as the easy integration with all other relays and test switches of COMBIFLEX design. ABB Automation 3
4 Easy to mount, easy to connect and easy to identify Mounting system strong on flexibility Mounting system The COMBIFLEX mounting system for relay equipment has been shaped over decades of practical experience from assembly of complete relay and control systems. The system is based on the 9" rack standard which permits simple combination of products using the same international standard. It offers various ways of building up the relay and control panels. All the minor details of COMBIFLEX integrate perfectly and form well-functioning panel designs. Connection system built for safety Connection system The COMBIFLEX connection system has been used over many decades and has shown itself as a very reliable system, combining flexibility with installation convenience. It is used for wiring panels and rack-mounting assemblies which require dual snap-in terminals for each electrical point. Moreover, the terminals are insulated from human contact, enhancing personnel safety. Safety is further improved by the fact that all the terminals are locked in place. This connection system lends itself to CAD-design as a tool when creating new relay and control systems. Designation system: Not seeing is believing Designation system The COMBIFLEX designation system is part of the invisible mounting and engineering system which nobody sees in everyday work but which would be immediately noticeable if it was missing. The designation system is the backbone of the process as it covers the entire chain from marking of relays and other components on the drawings to defining their connection points in circuit diagrams and connection tables. This system facilitates computer aided design. RHGP, 2, 2H and 4 mounted in 9" panel New Panel Maounting Cases RGHP The new RGHP panel mounting cases enables affordable cut out mounting of indiviual COMBIFLEX modules in panels. Test switches, powersupplies, auxilary relays and measuring relays of all types may thus be flush panel mounted. Any relay type of COMBIFLEX design can thus be mounted and used in existing panels. Mounting in typical switch-board panel cut-outs is more affordable with the new RHGP panel mounting cases. RHGP 4B, och 8 mounted in 9" panel New Retrofit Case for 900-series A version of the size new case RHGP 4B is intended for mounting in the same cut out space as the earlier 900-series relays made by ABB in Switzerland, e.g. the current relays type IKC 9xx, IKT9xx, the voltage relays type UKT9xx and the Rxx9xx-series etc. This is introduced to facilitate retrofit and extensions of earlier installations. 4 ABB Automation
