Embodiment Construction

[0043] As described above, the inventors have found that when the circuit breaker of a single branch of the power distribution module in the current power supply system fails and needs to be repaired or replaced, there is often the problem of "one move will affect the whole body", and the total circuit breaker of the system needs to be disconnected. power off. The main reason is that most of the current circuit breakers are installed in a fixed way, and it is inconvenient to disassemble. Only after the entire system is powered off, maintenance personnel can smoothly and safely perform maintenance or replacement operations on the faulty circuit breaker. Apparently, this kind of maintenance method that requires the entire system to be powered off often interrupts the data services provided by the data center to users, thereby causing a lot of inconvenience to people's production and life.

[0044] In order to solve the above problems, the inventor provided a hot-swappable assemb...

Abstract

The invention discloses a hot-plug assembly and a circuit breaking arrangement. The hot-plug assembly comprises a movable part and a fixed part which are electrically connected through an electrical connector. When a circuit breaker works, a contact pin of the electrical connector located in the movable part is correspondingly connected with a base located in the fixed part, and the fixed part breakovers with the circuit breaker inside the movable part. When the circuit breaker fails and needs maintenance and replacement, the movable part can be pulled out from the fixed part, and the circuitbreaker is electrically disconnected from the fixed part. Compared with fixedly installed circuit breakers, the pluggable structure can provide convenience for the maintenance and replacement of devices. An anti-electric shock protection mechanism of the fixed part isolates a first base inside the fixed part, thus electric shock is effectively avoided when maintenance personnel pull out the movable part under the condition that a system is not powered off, and safe hot plug of the circuit breaker is realized. By adopting the hot-plug assembly, the maintenance and replacement of the circuit breaker can be realized under the condition that the system does not need to disconnect a main circuit breaker, and the power supply of other power supply branches is not affected.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a hot-swappable assembly and a circuit breaker used in conjunction with a circuit breaker. Background technique [0002] With the rapid development of Internet technology and its applications, data centers have entered the stage of large-scale construction. People's demand for data acquisition is becoming more and more frequent, which undoubtedly poses a more severe challenge to the power supply system of the data center. When the power supply system fails, it is often necessary to interrupt the power supply for subsequent operation and maintenance. Once the power supply system is interrupted, it will be difficult for the data center to provide continuous data services, which will affect people's normal use. [0003] Specifically, at present, a power supply system usually includes multiple power distribution modules, and a circuit breaker is used in the power distr...
