Description

TECHNICAL FIELD

[0001] The present invention relates to a bridge switch; in particular, the present invention relates to a bridge switch inserted between two busbars. BACKGROUND

[0002] Power distribution systems use copper bars or copper busbars to connect the power input or the power distribution cabinet. However, the use of copper bars or copper busbars has many limitations. For example, copper bars and copper busbars are insulated from each other by air. In a high-voltage power distribution environment, the traditional power distribution system requires a large amount of space. To meet the space requirement, a larger cabinet is needed, which increases the cost of the cabinet. Moreover, the large space requirement means that the power transmission path is long, which indirectly increases the cost of copper needed for power transmission. The long power transmission path also causes power loss and generates waste heat, which limits the placement space and the ambient temperature of the power distribution system.

[0003] On the other hand, the connection by copper bars or copper busbars is mostly customized because copper bars or copper busbars need to be bent and stretched by processing. In other words, because copper bars or copper busbars need to be processed, the subsequent expandability is poor. If you want to extend or change the configuration, you can only replace the original copper bars or copper busbars to achieve the purpose of adjustment or expansion. In addition, exposed copper bars or copper busbars in a high-voltage construction environment must be de-energized before construction or routine maintenance for safety reasons. However, for a high-performance factory, the loss of production capacity caused by de-energization is difficult to estimate.

[0004] Although multiple sets of busbars arranged outside the cabinet can be used to replace the copper bars or copper busbars of the power distribution system, thereby reducing the required space or material cost of the power distribution system and improving the expandability of the power distribution system. However, the connection and management between multiple sets of busbars will become a subsequent problem. For example, if another busbar is directly connected to directly electrically connect multiple sets of busbars, the power supply between multiple sets of busbars cannot be controlled, and when a circuit breaker or an instantaneous high-current pulse occurs, the rear-end circuit cannot be protected. On the other hand, when there is a fault or a replacement is needed, the prior art cannot provide an effective hot replacement method, and the construction must be performed after de-energization.

[0005] On the other hand, the insertion device (PIU) of the prior art is used for power transmission between the busbar and the factory equipment. The prior art does not provide a quick connection device for more than two busbars.

[0006] As described above, the prior art still has many problems to overcome in the connection between multiple sets of busbars. SUMMARY

[0007] Therefore, the present application proposes a bridge switch to effectively solve the problems encountered by the prior art.

[0008] More particularly, one of the objects of the present application is to provide a bridge switch that can be connected between two busbars and can control the conduction between the busbars.

[0070] Any reference to elements referred to herein by names such as “first,” “second,” etc., does not generally limit the number or order of these elements. Rather, these names are used herein as a convenient way to distinguish two or more elements or instances of elements. Therefore, it should be understood that the names “first,” “second,” etc., in the claims do not necessarily correspond to the same names in the written description. Furthermore, it should be understood that references to first and second elements do not imply that only two elements can be used or that the first element must precede the second element. The terms “comprising,” “including,” “having,” “containing,” etc., as used herein are open-ended, meaning that they include but are not limited to.

[0071] The term “coupled” is used in this document to refer to a direct or indirect electrical coupling between two structures. For example, in one example of indirect electrical coupling, one structure may be coupled to another structure via a passive element such as a resistor, capacitor, or inductor.

[0072] In this invention, the terms "exemplary" and "for example" are used to mean "serving as an example, instance, or illustration." Any implementation or aspect described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other aspects of the invention. As used herein with respect to specified values ​​or characteristics, the terms "about" and "approximately" are intended to mean within a certain value (e.g., 10%) of the specified value or characteristic.

[0073] A preferred embodiment of the present invention is a bridging switch. The bridging switch includes a first insertion terminal, a second insertion terminal, and a switching component. The bridging switch connects two opposing buses, allowing the two buses to be quickly switched on or off. Furthermore, the insertion design allows for replacement or adjustment of the buses without interrupting power.

[0074] Specifically, please refer to Figure 1A and Figure 1B The bridging switch 10 includes a first insertion terminal 11 for insertion into a first busbar B1, a second insertion terminal 13 for insertion into a second busbar B2, and a switching member 12. A first side of the switching member 12 is electrically coupled to the first insertion terminal 11, and a second side of the switching member 12 is electrically coupled to the second insertion terminal 13. The switching member 12 includes a switching unit 121, which controls the electrical connection between the first side 1201 and the second side 1202.

[0075] The first bus B1 or the second bus B2 can be any bus for transmitting power, particularly for power transmission between equipment rooms in a factory. For example, the first bus B1 or the second bus B2 can be an armored bus, a molded bus, or a bus used around the enclosure of a switchboard system. This invention does not limit the type of the first bus B1 or the second bus B2.

[0076] The first bus B1 or the second bus B2 may have parallel-arranged conductor plates with a gap between two adjacent conductor plates. The first insertion end 11 and the second insertion end 13 can extend into and be positioned in the gap between two adjacent conductor plates through slots (B1S, B2S), thereby electrically coupling with the conductor plates within the bus. Taking the connection between the first insertion end 11 and the first bus B1 as an example, the first insertion end 11 can be coupled to the conductor plate of the first bus B1 via slot B1S, and fixed to the conductor plate of the first bus B1 by tightly pressing it against the conductor plate or by a fixing structure such as screws (e.g., set screws 114, 134). For example, the first insertion end 11 may have a set screw 114, which can adjust the spacing between the conductor plates of the first insertion end 11. When the first insertion end 11 is inserted into the slot B1S, the conductor piece on the first insertion end 11 is tightly connected to the conductor piece inside the slot B1S by tightening the set screw 114; when the first insertion end 11 needs to be removed, the set screw 114 can be loosened to release the first insertion end 11 from the slot B1S. However, the method by which the conductor piece on the first insertion end 11 is fixed to the conductor piece of the first busbar B1 is not limited to this. It should be noted that, although Figure 1A The first busbar B1 and the second busbar B2 are arranged in parallel, but the present invention is not limited to the relative position or angle between the first busbar B1 and the second busbar B2. For example, the first busbar B1 and the second busbar B2 can also be arranged at right angles. The bridge switch 10 can be inserted into the first busbar B1 and the second busbar B2 by changing the setting angle of the first insertion end 11 and the second insertion end 13, but it is not limited thereto.

[0077] The switching component 12 has a first side 1201 for input power and a second side 1202 for output power. It should be noted that the first side 1201 and the second side 1202 are only relative concepts corresponding to the input or output of power, respectively. The first side 1201 can also serve as one end of the output power, in which case the second side 1202 is one end of the input power. The first side 1201 of the switching component 12 and the first insertion terminal 11 can be electrically coupled through a conductor 111 made of copper, aluminum, or silver. It should be noted that the first insertion terminal 11 and the second insertion terminal 13 are only used to illustrate that their configuration is set to be able to couple and cooperate with the first bus B1 and the second bus B2, and are not intended to limit their component composition. For example, the first side 1201 of the switching component 12 can be directly inserted into the first bus B1 through a conductor 111. In this case, the portion of the conductor 111 inserted into the first bus B1 is the first insertion terminal 11 of this invention. On the other hand, the conductor piece 111 can also be combined with the plug conductor piece 112, which is configured to be inserted into the first busbar B1. The plug conductor piece 112 is inserted into the first busbar B1, and in this case, the plug conductor piece 112 is the first insertion end 11 of the present invention. Similarly, the second insertion end 13 can also be defined in the same way.

[0078] Reference Figure 1C The conductor sheet 111 can also be sealed by the sealing shell 113, thereby reducing the risk of electric shock to personnel or short circuits caused by exposed conductor sheet 111. Furthermore, the sealing shell 113 can be further filled with a curing filler, such as epoxy resin or silicone resin. Before curing, the curing filler can fill the gap between the conductor sheet 111 and the sealing shell 113, and after curing, it can act as an insulator and a rigid structure, completely sealing the conductor sheet 111 within the sealing shell 113. Therefore, the curing filler within the sealing shell 113 can further increase the overall waterproofness, explosion-proof performance, and safety.

[0079] The switching component 12 includes a switching unit 121, which switches between an on state and a non-on state according to a control command to control the electrical connection between the first side 1201 and the second side 1202. The control command can be mechanical, such as by manually moving a switch handle, or by using a spring, electromagnet, or other structure to provide a disconnection operation. The control command can also be non-mechanical, such as light, sound, or electricity. When the switching unit 121 is in the on state, the first side 1201 and the second side 1202 of the switching component 12 are electrically connected. At this time, power from the first bus B1 can be transmitted to the second bus B2. Conversely, when the switching unit 121 is in the non-on state, the first side 1201 and the second side 1202 are not electrically connected. At this time, the first bus B1 and the second bus B2 cannot be electrically coupled.

[0080] With the above configuration, because the first insertion terminal 11 and the second insertion terminal 13 have sufficient safety and leakage protection, the first insertion terminal 11 is configured to allow insertion into the first busbar B1 when it is not de-energized, and the second insertion terminal 13 is configured to allow insertion into the second busbar B2 when it is not de-energized. Furthermore, the switch component 12 can be preset to break the circuit to improve safety when installing the bridge switch 10, preventing operator error from causing short circuits or other abnormal circuit conditions between the first busbar B1 and the second busbar B2. Therefore, the bridge switch 10 can be installed without interrupting power (hot-swappable).

[0081] In one embodiment, please refer to Figure 2A The switching component 12 also includes a control unit 122, which is coupled to the switching unit 121 and provides control commands CI. The control unit 122 is, for example, a computer, microprocessor, or FPGA with computing capabilities. By receiving instructions from the operator or by detecting the current or voltage value flowing through the switching unit 121, the control command CI is provided to the switching unit 121, thereby controlling the on or off state of the switching unit 121.

[0082] In one embodiment, please refer to Figure 2B The switching component 12 also includes a communication unit 123, which is coupled to the switching unit 121 and receives signals providing control commands CI via a wireless transmission WC. The communication unit 123 is, for example, a module of a wireless remote communication means such as a Bluetooth receiver, an infrared receiver, or a wireless network receiver. After receiving a communication signal from a remote location, the communication unit 123 can provide control commands CI to the switching unit 121, thereby controlling the on or off state of the switching unit 121.

[0083] The switching of the switching unit 121 can be made more automated and save a lot of manpower by using the control unit 122 or the communication unit 123. It should be noted that... Figure 2A and Figure 2B The embodiments shown can be implemented individually or in combination. On the other hand, the control unit 122 or the communication unit 123 does not necessarily need to be housed within the housing of the switch member 12. For example, the control unit 122 can be a computer or a central control console connected to the switch unit 121 via a transmission line and providing control commands CI, but is not limited thereto.

[0084] In one embodiment, the switching unit 121 can be an air circuit breaker (ACB) or a molded case circuit breaker (MCCB). A suitable switching unit 121 can be selected based on the amount of current transmitted between the first bus B1 and the second bus B2. For example, when the current is below 1600 amperes, a molded case circuit breaker can be used, while when the current is higher, an air circuit breaker can be used to achieve better breaking performance. Furthermore, compared to molded case circuit breakers, air circuit breakers not only have the advantage of being able to operate at higher currents, but their breaking principle also makes it easier to set up remote or automatic control mechanisms.

[0085] In one embodiment, please refer to Figure 3A and Figure 3B The bridged switch 10 also includes a housing 14. A switch member 12 is disposed within the housing 14, and a first insertion end 11 and a second insertion end 13 are disposed outside the housing 14 and on a first surface 1401 of the housing 14. The housing 14 can accommodate the switch member 12, and the first insertion end 11 and the second insertion end 13 protrude from the housing 14. Generally, the housing 14 may have a door panel 141, thus facilitating operation of the switch member 12. The first surface 1401 of the housing 14 has through holes corresponding to the first insertion end 11 and the second insertion end 13, through which a conductor piece connected to the switch member 12 can pass through the housing 14 and form or couple to the first insertion end 11 and the second insertion end 13. The first side 1401 of the housing 14 is preferably selected from the side of the housing 14 opposite to the door panel 141, so that when the bridged switch 10 is installed on the first busbar B1 and the second busbar B2, the switch member 12 can be directly operated by opening / closing the door panel located on the front, but is not limited thereto.

[0086] In one embodiment, please refer to Figure 4The first surface 1401 of the housing 14 has at least one guide mounting structure 142 configured according to the structure of the first bus B1 or the second bus B2. Specifically, the first surface 1401 of the housing 14 faces the first bus B1 and / or the second bus B2. When the bridged switch 10 is disposed on the first bus B1 and / or the second bus B2, the at least one guide mounting structure 142 on the first surface 1401 can assist the installer in installing along the contour or structure of the first bus B1 and / or the second bus B2. Guided by the at least one guide mounting structure 142, the installer can position the bridged switch 10 with housing 14 in the correct position. Furthermore, at least one guide mounting structure 142 may also have a locking means that can be detachably engaged with the first bus B1 and / or the second bus B2. Thus, when the bridged switch 10 with housing 14 is disposed on the first bus B1 and / or the second bus B2, the at least one guide mounting structure 142 can provide engagement stability. The housing 14 with guide mounting structure 142 can reduce the risk of the bridged switch 10 disengaging from the first bus B1 and / or the second bus B2 due to vibration or accidental contact, and provides auxiliary engagement force, preventing instability or loosening caused by the bridged switch 10 relying solely on the engagement force of the first insertion end 11 and the second insertion end 13 when inserted into the first bus B1 and / or the second bus B2. It should be noted that although in this embodiment, at least one guide mounting structure 142 is disposed on the first surface 1401, the first insertion end 11 and the second insertion end 13 of the present invention can be disposed on the same or different surfaces of the housing 14. When the first insertion end 11 and the second insertion end 13 are disposed on different surfaces, at least one guide mounting structure 142 can be adjusted and disposed on any surface of the housing 14 as required.

[0087] In one embodiment, please refer to Figure 5The first insertion terminal 11 has a first-phase power supply terminal P1, a second-phase power supply terminal P2, and a third-phase power supply terminal P3; wherein the first-phase power supply terminal P1 is coupled to the switching member 12 via a first conductor path 1111, the second-phase power supply terminal P2 is coupled to the switching member 12 via a second conductor path 1112, and the third-phase power supply terminal P3 is coupled to the switching member 12 via a third conductor path 1113. Specifically, the first busbar B1 can transmit power signals of the same or different phases by adjusting the configuration within the first busbar B1. Taking a three-phase power supply as an example, the first busbar B1 can transmit power signals with a phase difference of 120 degrees. The first insertion terminal 11 can lead out power signals of different phases from the first busbar B1 through the first-phase power supply terminal P1, the second-phase power supply terminal P2, and the third-phase power supply terminal P3. The power signals of different phases are transmitted to the switching member 12 through the first conductor path 1111, the second conductor path 1112, and the third conductor path 1113. Similarly, the switching component 12 can control the conduction or disconnection of power signals of different phases transmitted from the first conductor path 1111, the second conductor path 1112, and the third conductor path 1113, so as to transmit them to the second bus B2. Through the configuration of this embodiment, different power supply methods can be provided according to the plant equipment, so that the bridge switch 10 can be used with any type of power supply.

[0088] In one embodiment, please refer to Figure 6 The bridging switch 10 may further include a meter module 15 coupled to the switching member 12, which displays electrical data flowing through the switching member 12. For example, the meter module 15 may read the current value, power, or other power parameters flowing through the switching member 12 using a current meter or other existing power parameter reading means. The measured values ​​may be displayed on a display or other means. In one embodiment, the bridging switch 10 may further include at least one indicator module 16 coupled to the switching member 12, which indicates whether the switching member 12 receives power from the first busbar B1 from the first insertion terminal 11. The at least one indicator module 16 may be a light, sound, or other existing warning means, thereby providing the operator with information about the power status of the switching member 12.

[0089] In one embodiment, please refer to Figure 7 The first insertion terminal 11 can be configured as multiple first insertion terminals 11, and the first bus B1 can also be configured with multiple first slots to correspond to the multiple first insertion terminals 11. Similarly, the second insertion terminal 13 can also be configured as multiple second insertion terminals 13, and the second bus B2 can also be configured with multiple second slots to correspond to the multiple second insertion terminals 13. It should be noted that... Figure 7The illustration is merely an example and is not intended to limit the number of insertion terminals and slots in this embodiment. With this arrangement, the amount of current that the first insertion terminal 11 can withstand or accept can be increased accordingly, thereby achieving the purpose of increasing the current capacity of the bridged switch 10 (high-capacity bridged switch).

[0090] By connecting two or more busbars using a bridging switch, two or more busbars can be connected quickly and safely. Furthermore, the bridging switch can also function as a circuit breaker or circuit interruption point, allowing the busbar to be configured with interruption or safety points during power transmission to improve the overall safety of the circuit transmission and further protect the plant equipment connected to the busbar.

[0091] The prior description of the invention is provided to enable those skilled in the art to make or implement the invention. Various modifications to the invention will be apparent to those skilled in the art, and the general principles defined herein can be applied to other variations or embodiments can be implemented in combination with or independently without departing from the spirit or scope of the invention.
