Description

Technical Field

[0001] This utility model relates to the field of power transmission and distribution equipment technology, and in particular to a multifunctional three-phase common-box current diversion device. Background Technology

[0002] Currently, commercially available three-phase common-enclosure GIS equipment still has certain limitations in terms of current transmission redirection. Some products can only achieve three-phase common-enclosure current transmission redirection in a single direction, resulting in relatively limited functionality and failing to meet the needs of flexible switching between multiple circuits and directions in complex power systems. Other products can achieve three-phase common-enclosure current transmission redirection in multiple directions, but their structures generally suffer from a large number of components, leading to a large overall device size, complex manufacturing processes, and difficulties in achieving standardized and modular production. Furthermore, these devices are incompatible with other GIS functional components, resulting in insufficient functional expandability, thus limiting the optimization of the overall layout of GIS equipment and the improvement of resource utilization efficiency during application. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional three-phase common-box current diversion device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multifunctional three-phase common-box current diversion device, including a first port, a second port, a third port and a fourth port, all of which can be used as input or output terminals of the three-phase common-box current. Conductor connectors are provided at the first port, the second port, and the third port to enable electrical connection between the port and the internal conductor. Current adapters, located between ports, are used to redirect and distribute input current to other ports; A switching conductor is used to control the connection or disconnection of three-phase common-box current during current transmission. The current can be input from any port and distributed to the other three ports via the current adapter.

[0005] According to the above technical solution, the switching conductor is used to switch between input current and output current.

[0006] According to the above technical solution, the current adapter is located in the middle position between the first port, the second port, the third port and the fourth port.

[0007] According to the above technical solution, the conductor connectors are identical structural components, used to achieve a unified configuration in multiple ports.

[0008] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, by setting conductor connectors, current adapters, and switching conductors, realizes multi-directional transmission and on / off control of three-phase common-box current between four ports. The first, second, and third ports all use conductor connectors with the same structure, which not only reduces the types and number of components but also facilitates standardized production. The current adapters are used to achieve intermediate current redirection between ports, while the switching conductors are used to control the current connection or disconnection, thereby simplifying the overall layout, reducing material consumption, and improving the versatility and scalability of the device.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example: Reference Figure 1 A multifunctional three-phase common-box current diversion device is disclosed. The device includes four ports and conductor components connected to them, which are used to realize multi-directional transmission and on / off control of three-phase current.

[0013] In this system, port 1, port 2, port 3, and port 4 serve as input or output ports for the three-phase common-box current circuit, respectively. Any one of the four ports can be used as an input terminal, while the other three ports serve as output terminals, enabling multi-directional current transmission. For example, when current is input through port 1, it can be transmitted to port 2, port 3, and port 4 via an internal transfer structure; similarly, when port 2 is the input terminal, the current can be distributed to port 1, port 3, and port 4, and so on.

[0014] The first port 1, the second port 2, and the third port 3 are all equipped with conductor connectors 5, which are used to achieve a reliable electrical connection between the port and the internal conductors. The current adapter 6 acts as an intermediate deflector, allowing the input current to be diverted or redirected to the target port according to functional requirements. The switching conductor 7 not only transmits current but also functions to connect or disconnect the current, thereby controlling the direction of current flow.

[0015] Furthermore, in the main conductive circuit, ports 1 to 4 can be connected to GIS functional components such as disconnecting switches, grounding switches, cable terminals, bushings, current transformers, and circuit breakers, respectively; in the non-main conductive circuit, they can be connected to GIS functional components such as fast grounding switches, maintenance grounding switches, voltage transformers, and surge arresters, so as to realize extended functions such as current measurement, protection, and isolation.

[0016] With the above structure, this utility model can achieve multi-directional transmission and on / off control of three-phase current while keeping the number of parts small and the structure simple, and has the ability to connect various GIS functional components, thereby improving the versatility and standardization of the device.
