technical field

The utility model relates to the electrical field, in particular to a mechanism and a device for supporting a hot-swappable circuit breaker, and more particularly to the device used in the field of logistics for supporting the hot-swappable circuit breaker.

Background technique

In the field of logistics, especially in the airport logistics system, it is necessary to minimize the impact of the power supply failure or maintenance requirements of its subsystems on the operation of the logistics line during operation. Traditional drawer-type or fixed partition power supply cabinets can meet the above requirements, but their volume and weight are too large, and the protection level is difficult to meet the requirements for on-site installation and use in airport logistics. Under this premise, realizing the hot-swap function of the subsystem power supply switch (that is, the circuit breaker) in the non-standard power supply cabinet can meet the above-mentioned requirements at the same time.

The circuit breaker can be electrically connected to the bus bar and powered by the bus bar. A non-hot-swappable power supply solution used in existing non-standard power supply cabinets, where the circuit breaker can be electrically connected to the busbar through a busbar adapter. In the above solution, the circuit breaker is fixedly connected to the bus adapter, which cannot realize the hot swap function.

On the other hand, the circuit breaker can realize the hot-swap function through a matching circuit breaker base with a circuit breaker plug-in structure. In this case, the main switch can not be cut off, and the circuit breaker can be inserted and pulled out while ensuring the normal power supply of other subsystem circuits, so as to realize functions such as replacing the faulty circuit breaker.

Changing the above non-hot-swappable power supply scheme to a hot-swappable power supply scheme, and connecting the supporting circuit breaker base to the above-mentioned busbar adapter is a feasible solution to realize the hot-swappable function. However, in practical applications, different manufacturers produce various circuit breakers and supporting bases, which have interfaces of different specifications, and it is difficult to adapt to different busbar adapter products.

Utility model content

An object of the present utility model is to provide a circuit breaker base assembly and a circuit breaker hot plug device, which can effectively solve the problem of matching the circuit breaker and its supporting base with the busbar adapter product. Another object of the present utility model is to provide a circuit breaker base assembly and a circuit breaker hot plug device, which have a simple structure, low cost and convenient installation.

In order to achieve the above object, the utility model proposes a circuit breaker base assembly, including: a base, which has a first installation side and a circuit breaker insertion side, the first installation side is inserted into the circuit breaker The sides are opposite sides of the base, and the base includes: a plug-in interface with a pluggable structure, which is arranged on the plug-in side of the circuit breaker, and is configured so that the base can connect with a The circuit breaker is electrically connected; at least two first connection holes, which are arranged on the first installation side; at least two first connection pieces; a mounting plate, which includes: at least two base connection holes, which are connected to the The positions of the first connecting holes correspond to each other, and it is configured to pass through the connecting holes of the base and the first connecting holes through the first connecting member to connect and fix the mounting plate on the base. Side: at least two adapter connection holes, which are configured so that the circuit breaker base assembly can be connected and fixed to a busbar adapter through the adapter connection holes through a connecting piece.

In the above-mentioned way, the above-mentioned circuit breaker base assembly is composed of the circuit breaker base matched with the circuit breaker and the installation plate that acts as a connection conversion, which can solve the problem of circuit breaker when converting the non-hot-swappable power supply solution to the hot-swappable power supply solution. It is simple and flexible, low cost and easy to install.

In another exemplary embodiment, the circuit breaker base assembly further includes expansion bolts embedded in the at least two base connection holes; wherein, the first connection hole runs through the base, and its two sides The openings are respectively on the first installation side and the circuit breaker insertion side, and the first connecting member is a screw, which is configured to be screwed into the first connection hole and the circuit breaker insertion side sequentially. The expansion bolts are used to connect and fix the installation plate on the first installation side of the base.

In the above embodiment, the expansion bolt has a bolt connection hole coaxial with the base connection hole along its axis. In this case, the mounting plate can be connected and fixed on the first connecting part of the base through the first connecting member passing through the first connecting hole and the bolt connecting hole sequentially from the connecting side of the circuit breaker. mounting side. Due to the existence of expansion bolts, the fixing stroke of the first connecting piece, that is, the screw, is extended, and the contact area between the mounting plate and the first connecting piece is indirectly increased, so that the contact area between the base and the mounting plate The connection is fixed more firmly. In order to prevent misplugging or falling off, when the circuit breaker is plugged and pulled out on the circuit breaker base, a relatively large force is required to pull the circuit breaker out of the circuit breaker base. With the above implementation manner, the base of the circuit breaker can be more firmly connected to the installation plate, so that the hot swapping function can be realized more reliably.

In another exemplary embodiment, the adapter connection hole is an elongated hole.

Generally speaking, the external busbar adapter also has connection holes corresponding to the adapter connection holes on the mounting plate, so that the circuit breaker base assembly can be connected and fixed to the busbar adapter through a connecting piece .

At the same time, due to the first connecting piece and the mounting plate, they are not charged under working conditions. In the case that the mounting plate is a metal plate, if a leakage occurs to make it electrified, it will adversely affect the normal operation of the circuit breaker or even make it unable to work normally. In the manner described above, the excess charge on the mounting board can be released through the ground, thereby eliminating the effect of leakage and ensuring the normal operation of the circuit breaker.
