Abstract
The invention discloses a vacuum circuit breaker which includes a vacuum arc-extinguishing chamber, a transverse beam and a crank arm box. The vacuum circuit breaker is characterized in that the vacuum arc-extinguishing chamber is connected with the crank arm box through the transverse beam, the inside of the vacuum arc-extinguishing chamber is provided with a fixed contact, a moving contact, a driving mechanism, a control module and an arrester, the moving contact is connected with the driving mechanism which is connected with the control module, the arrester is arranged between the fixed contact and the moving contact in an electrical connection mode, and an insulation mechanism is arranged on the contact portion of the driving mechanism and the control module. The vacuum circuit breaker has the advantages of being compact in structure, being convenient and fast in operation during the using process, convenient to install and highly reliable. Besides, the safety and the stability of the vacuum circuit breaker are greatly improved due to the arrangement of the arrester and insulating ceramics, the service life of the vacuum circuit breaker is prolonged, the working efficiency is improved and costs are reduced.
