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...

The invention discloses a hot plug assembly and a circuit breaker. The hot plug assembly includes a movable part and a fixed part which can be electrically connected to each other through an electric connector. When the circuit breaker is working, the pins of the electrical connector located on the movable part are correspondingly connected to the base located on the fixed part, and the fixed part is connected to the circuit breaker inside the movable part. When the circuit breaker fails and needs to be repaired and replaced, the movable part can be pulled out from the fixed part, and the circuit breaker is electrically disconnected from the fixed part. Compared with the fixed installation circuit breaker, the pluggable structure can facilitate the maintenance and replacement of components. The anti-shock protection mechanism of the fixed part isolates the first base inside the fixed part, effectively avoiding electric shock when maintenance personnel pull out the movable part when the system is not powered off, and realizes safe hot swapping of the circuit breaker. The hot-swappable assembly can realize maintenance and replacement of the circuit breaker without disconnecting the main circuit breaker in the system without affecting the power supply of other power supply branches.
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...
