HMC-1 and HMC-2 operating mechanisms Designed for reliable switching
HMC-1 and HMC-2 for optimized performance HMC-1 and HMC-2 are the latest members of the new HMC family of operating mechanisms. They use the same well-proven operating principle as their predecessors HMB, but are based, like the HMC-4, on the latest technology for highest reliability. They are an ideal replacement for existing HMB-1 and HMB-2 mechanisms.
Applications Operating mechanisms are a key component of high voltage circuit-breakers. They find their application in live tank breakers, dead tank breakers, generator circuit-breakers and gas-insulated switchgear.
Adaptation and time to market The general design of HMC allows for superior adaptability compared to other types of operating mechanism principles. Leading to the shortest time-to-market; guaranteed also by compatibility with all HMB-1 and HMB-2 applications.
Innovation and reliability Our experience is based on: – 30 years of design and manufacturing – more than 110,000 operating mechanisms produced – more than 100 different product applications
The features of HMC-1 and HMC-2 – Highest switching reliability by using new design principles like – cylinder made from gray cast iron – new robust valve technology – wiper protected sealing systems – gearless pump unit – integrated close-interlocking with damage-free design – Lowest life-cycle cost due to – being maintenance-free for 10,000 CO-operations – easily accessible and exchangeable modules – Shortest time-to-market due to – simple and easy adaptation to all circuit-breaker types – nearly identical travel curve as HMB, allowing alternative operating mechanisms test according to IEC62271-100 – Highest power density on market for most compact design of equipment – Suitable for circuit-breaker applications up to 245 kV
The development of the HMC mechanisms is based on ABB‘s long history of operating mechanisms and past history with HMB. This experience has been used for many innovative solutions and resulted in patented new technologies. As a result end users and manufacturers of high voltage equipment can expect the highest switching reliability available. Life cycle cost HMC-1 and HMC-2 are compact and reliable operating mechanisms, designed with easily accessible modules. Due to their advanced design they are free of scheduled maintenance for 10,000 CO-operations – resulting in the lowest life cycle cost possible.

One-fits-all concept The one-fits-all concept of HMC-1 and HMC-2 is covering all installation orientations with one design. This means that all applications, either vertical or horizontal, can be served. To adapt to different energy demands only the number of springs is varied. The diversity of mechanisms at the customer is kept to the lowest and allows an efficient inventory management.

Basic technical data for the variants of HMC. Other data, defining secondary technology, are customer specific and part of the customization process of the operating mechanism. Easy plug-and-play of customer-specific components, like coils or motor, guarantees late-customization at the switchgear manufacturer’s site. Therefore lead-times can be reduced to a minimum.
