Title:
DIRECT-CURRENT CIRCUIT BREAKER HANDCART AND DIRECT-CURRENT SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/087757
Kind Code:
A1
Abstract:
A direct-current circuit breaker handcart (01) and a direct-current switch device (02). The direct-current circuit breaker handcart (01) comprises a support frame (10), a current-carrying element (30), a current-converting element (40), a repulsion assembly (33) and an energy absorption element (50). The support frame (10) comprises a support surface (20), and the current-carrying element is located on the support surface (20) and comprises a main circuit breaker (31) and an auxiliary circuit breaker (32), which are electrically connected to each other. The current-converting element (40) is located on the support surface (20) and is electrically connected to the current-carrying element (30), and comprises a current-converting capacitor (41), a current-converting inductor (43), a current-converting switch assembly (44) and a current-converting capacitor charger (42), which are electrically connected to one another. The repulsion assembly (33) is configured to control the on/off of the main circuit breaker (31). The energy absorption element (50) is located on the support surface (20) and is electrically connected to the current-carrying element (30) and the current-converting element (40). Integrating main components in a direct-current cabinet onto one direct-current handcart facilitates the assembly, transport, repair and maintenance of multiple components in the direct-current cabinet, thereby effectively improving the control convenience and safety performance of the direct-current cabinet.
