HVS-63S is the cost-optimized solution for power plant units of up to 200 MW Innovative breaking chamber The breaking chamber of HVS-63S is based on the highly reliable technology of open-type GCB HVR-63. The breaking chamber includes the double main contacts for double current commutation for higher stability of resistance to ensure the maintenance span of 20 years or 10,000 close-open operations. Featuring the advantage of a hydraulic spring operating mechanism, HMB-1, it uses 50 percent less energy compared to mid-sized GCBs for a more compact design and lower lifecycle costs. Pressure relief device Standard feature in the breaking chamber to improve satefy and availability. Erosion monitoring system The breakthrough application of head-to-head contact system in HVS-63S enables an innovative built-in mechanical solution for a direct measurement and indication of arcing contact erosion. This real-time indication of the remaining time to service enables a timely planning of maintenance and increases the availability and reliability of the plant. The most reliable spring drive HMB-1 CIGRE study (conducted in 2012) on high-voltage circuit breaker failures and defects in service revealed that the availability of the circuit breakers depends primarily on the reliability of the operating mechanism. These results from the study have endorsed the hydro mechanical spring drive as the most reliable operating mechanism for GCB applications. The hydraulic spring operating mechanism combines the advantages of a hydraulic operating mechanism with those of spring energy storage system with higher stability in the full range of the GCB operating temperatures and high consistency of timing during the enitre lifespan for a safe performance. Combined disconnector-earthing switch and earthing switch-starting switch Combination of line disconnector with earthing switch and earthing switch with starting switch by three-positions disconnector allows the use of only one drive per disconnector for the lowest lifecycle cost, simplification of the switchgear and leaner management of the spare parts. Low environmental impact Only 5.1 kg of SF 6 in three poles and a leakage rate lower than 0.1 percent per year. The advanced functions of GMS600 monitoring system, such as SF 6 and temperature monitoring and trending (available on request), facilitates the control of such parameters. Compact design and easy handling HVS-63S is fully assembled and tested at the factory for substantial cost and time saving in installation and commissioning process. Its compact design fits into a standard 20-feet container for easy transportation, handling and storage. Combined with its plug-in system it leads to a simpler and quicker installation on-site. 6 HVS-63S Generator circuit-breaker ABB
