e²BRAVO Vacuum Circuit Breaker

CHARACTERISTIC
e²BRAVO vacuum circuit breaker is a modern medium-voltage switching apparatus  adapted for use with medium-voltage comprising module switchgears as well as in stationary version as a replacement for old low-oil apparatus. e²BRAVO is available in a wide range of rated voltages (7.2 - 17.5 kV) and in various configurations due to the horizontal and vertical scale and additional deviceequipment. High quality vacuum chambers and reliable operating mechanism ensure the achievement of high switching and mechanical durability at the level of 30000 on-offcycles.

DESIGN

e²BRAVO circuit breaker has been equipped with a stored-energy operating mechanism. Operating system is placed in the middle of the front part of the circuit breaker body. Such an arrangement of the assemble provides very good access to its components and facilitates maintenance and service.

ADVANTAGES OF THE e²BRAVO CIRCUIT BREAKER

APPLICATION

High reliability of the e²BRAVO circuit breakers family combined with their very good electrical parameters make them ideal for applications in the commercial-, industrial-and mining power companies, where above mentioned aspects are essential. e²BRAVO circuit breakers can also be successfully used as a replacement of old low-oil equipment by using special retrofitting designs. The design of retrofit kits ensures fully interchangeability with the previous used  low-oil circuit breakers of the following types: SCI / SCJ, WMPWZ, WMSWP and IO.

The order for KGHM SA, consisted of modernization of withdrawable modules of the RD-1 switchgear. The units have been equipped with e²BRAVO vacuum circuit breakers and a set of interlocking compatible with the modernized bays. Thanks to this, the modernized RD-1 switchgear significantly increased the operational safety and reliability of work. The replacement of withdrawable modules has been made without interfering with the construction and control circuits of the switchgear and with the use of driving, insulating and connecting elements from the modernized element. The exchange could be carried out without the switchgear being switched off, which ensured the continuity of the plant's operation.
