Purpose of the development: Bavra The system allows you to switch the load on backup power source for the minimum time to prevent failures of systems management, conservation continuity processes and ensure the stable operation of the electric motors. The main components that provide the possibility of implementing Bavra are fast switching devices, power management, and microprocessor-based relay, receiving information about how to disable the main input and gave the command to connect a backup power source. Especially for systems Bavra been developed vacuum switches BB / TEL-10-31,5 / 2000_Q, which, in co-operation with the control unit CM_1501_01 (4), provides a complete on-time up to 24 ms and the total trip time of 12 ms, which considerably surpasses its competition

Recommended application field: Objects of electricity companies using continuous technological cycles equipped with computer automation, high-voltage electric motors, high-voltage and low-voltage motor drive pumps, including companies specializing in the extraction and processing of oil and gas, metallurgy, water supply, sewerage and so on.

Technical characteristic: 1 Rated voltage vacuum switches BB / TEL-10-31,5 / 2000_Q, 10 kV 2 Rated current vacuum switches BB / TEL-10-31,5 / 2000_Q, VA 2000 3 Rated breaking current vacuum switches BB / TL-10-31,5 / 2000_Q, 31.5 kA 4 Switching resources of vacuum switches BB / TEL-10-31,5 / 2000_Q, cycles IN 30000 5 Time setting of vacuum switches BB / TEL-10-31,5 / 2000_Q, 20 ms 6 Tripping time of vacuum switches BB / TEL-10-31,5 / 2000_Q, 8 ms 7 Time recognition command control unit CM_1501_01 (4), 4 ms 8 Time control relay Bavra SCM21-X, 25 ms 9 Full time switch to the backup power supply of less than 50 ms

Advantages over analogues: The new design of the drive based on the "magnetic latch" provides vacuum switches BB / TEL-10-31,5 / 2000_Q superior performance in operations on and off. Due to its high adaptive capacity BB / TEL-10-31,5 / 2000_Q, it allows for Bavra on the basis of a large range of cells operated switchgear and CSR both domestic and foreign production.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: - increasing the reliability of power supply to consumers, - ensuring continuity of electricity supply to consumers, - increase of residual stresses on the tires of a 6 (10) / 0,4 kV, - reducing the likelihood of failure of computer control systems, - ensure the successful self-starting motor, - the possibility of using the cells operated in switchgear and CSR.

Description of the development:
()
Quick automatic input provision allows for a continuous process, which stops short term is likely to prejudice the final product, process equipment or pose a risk to staff. Applications Colours reduces the number of starts of motors than significantly increases their resources and resource related systems (piping, pumps, etc.). In connection with fast switching operation of Bavra, as a rule, does not lead to the restart of computer control systems, to avoid data loss and to maintain constant control over the managed objects.
