Packaging box for high-voltage vacuum circuit breaker

Abstract

The invention discloses a packaging box for a high-voltage vacuum circuit breaker. The packaging box for the high-voltage vacuum circuit breaker comprises a packaging box, wherein a buffering device is arranged at the bottom of the inner cavity of the packaging box, limiting devices are arranged on the two sides of the inner cavity of the packaging box, clamping plates are arranged on the two sides of the top of the buffering device, a placing frame is arranged at the top of the buffering device and between the two clamping plates, clamping devices are arranged on the two sides of the inner cavity of the placing frame, connecting blocks are fixedly arranged on the tops of the two sides of the inner cavity of the placing frame, and a clamping groove is formed in the top of the connecting block. According to the packaging box for the high-voltage vacuum circuit breaker, the packaging box, the buffering device, the clamping plates, the placing frame, the clamping devices and the connecting blocks a cover plate and a clamping block are arranged, so that the high-voltage vacuum circuit breaker can be buffered and protected when transporting, so that the transportation quality is improved, and meanwhile, the problem that the interior of the packaging box cannot effectively protect the vacuum circuit breaker, the vacuum circuit breaker is prone to damage in the transportation processare solved.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breaker packaging, in particular to a packaging box for a high-voltage vacuum circuit breaker. Background technique [0002] The circuit resistance of the vacuum circuit breaker is the main heat source that affects the temperature rise, and the circuit resistance of the interrupter usually accounts for more than 50% of the circuit resistance of the high-voltage vacuum circuit breaker. The contact resistance of the contact gap is the main component of the circuit resistance of the vacuum interrupter. Partly, because the contact system is sealed in the vacuum interrupter, the heat generated can only be dissipated to the outside through the dynamic and static conductive rods. The vacuum circuit breaker is high in the arc extinguishing medium and the insulation medium of the contact gap after arc extinguishing. It is named after the vacuum, which has the advantages of small size, light weight, ...
