Title:
HOT PLUGGABLE ASSEMBLY USED IN COOPERATION WITH CIRCUIT BREAKER AND CIRCUIT-BREAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/125256
Kind Code:
A1
Abstract:
Disclosed are a hot pluggable assembly and a circuit-breaking device. The hot pluggable assembly comprises a movable part and a fixed part electrically connected to each other through an electrical connector. When a circuit breaker works, insertion pins (12a, 12c), located on the movable part, of the electrical connector are respectively connected to bases (12b, 12d), located on the fixed part, of the electrical connector, and the fixed part communicates with the circuit breaker inside the movable part. When the circuit breaker breaks down and needs to be maintained and replaced, the movable part can be pulled out of the fixed part, and the circuit breaker is electrically disconnected from the fixed part. Compared with a fixedly mounted circuit breaker, the pluggable structure can facilitate the maintenance and replacement of a device. An electric shock protection mechanism of the fixed part isolates a first base inside the fixed part, electric shock can be effectively prevented when maintenance personnel pull out the movable part under the condition where the system is not powered off, and safe hot plug in and out of the circuit breaker is realized. By using the hot pluggable assembly, maintenance and replacement of the circuit breaker can be realized under the condition where the system does not need to disconnect a total circuit breaker, and the power supply of other power supply branches is not affected.
