Description

TECHNICAL FIELD

[0001] The utility model relates to a bridging switch; in particular to a bridging switch inserted between two busbars. BACKGROUND

[0002] The power distribution panel system uses copper bars or copper strips to connect the input end of the power supply or the internal part of the power distribution panel. However, the use of copper bars or copper strips has many limitations. For example, copper bars and copper strips are insulated from each other by air. In a high-voltage power distribution environment, the traditional power distribution panel system requires a large amount of space. To meet the space requirement, a larger cabinet is needed, which increases the cost of the cabinet. In addition, the large space requirement also means that the power transmission path is lengthened, indirectly increasing the cost of copper required for power transmission. The lengthening of the power transmission path also causes power loss and generates waste heat during power transmission, which greatly limits the placement space and environmental temperature of the power distribution panel system.

[0003] On the other hand, the connection between the copper bars or copper strips is mostly customized because the copper bars or copper strips need to be bent and stretched through processing. In other words, because the copper bars or copper strips need to be processed, the subsequent expandability is not good. If you want to extend or change the configuration, you can only replace the original copper bars or copper strips to achieve the purpose of adjustment or expansion. In addition, in a high-voltage construction environment, for safety reasons, power must be cut off before construction or daily maintenance can be carried out. However, for high-performance factories, the loss of production capacity caused by power cut-off is difficult to estimate.

[0004] Although multiple sets of busbars arranged outside the cabinet can be used to replace the copper strips or copper bars of the power distribution panel system, thereby reducing the required space or material cost of the power distribution panel system and improving the expandability of the power distribution panel 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 needs to be replaced, the prior art cannot provide an effective hot replacement means, and power must be cut off before construction can be carried out.

[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 connecting two or more busbars.

[0006] As can be seen from the above, in the connection between multiple sets of busbars, the prior art still has many problems to be overcome. UTILITY MODEL CONTENT

[0070] Any reference in this text to an element using a designation such as "first," "second," and the like, is generally not limiting, unless otherwise determined by context, as these designations can be used merely as a matter of convenience in any context. Accordingly, it will be understood that the use of "first," "second," and the like, to describe a name in the claims is not necessarily limited to the same name in the written description. Further, it will be understood that a reference to first and second elements does not mean that only two elements can be employed or that a first element must precede a second element. As to the use of "comprise," "comprises," "comprising," "include," "includes," "including," and the like, such terms, which are open-ended, are intended to mean including but not limited to.

[0071] The term "coupled" is used herein to express either a direct or indirect electrical coupling between two structures. For example, in one example of indirect electrical coupling, one structure can be coupled to another structure via a passive element such as a resistor, capacitor, or inductor.

[0072] In the present utility model, the words "exemplary", "for example" are used to mean "serving as an example, instance, or illustration". Any implementation or aspect described herein as "exemplary", "for example" is not necessarily to be construed as preferred or advantageous over other aspects of the present utility model. The terms "about", "approximately" as used herein in relation to a specified value or characteristic are intended to mean within a certain value (e.g., 10%) of the specified value or characteristic.

[0073] According to a preferred embodiment of the present utility model, a bridge switch is provided. The bridge switch includes a first insertion end, a second insertion end, and a switch member. The bridge switch connects two opposite busbars. The two busbars can be quickly turned on or turned off. In addition, the plug-in design can be replaced or adjusted without power off.

[0074] Specifically, please refer to Figure 1A and Figure 1B The bridge switch 10 includes a first insertion end 11 for insertion into a first busbar B1, a second insertion end 13 for insertion into a second busbar B2, and a switch member 12. The first side of the switch member 12 is electrically coupled to the first insertion end 11, and the second side of the switch member 12 is electrically coupled to the second insertion end 13; wherein the switch member 12 includes a switch unit 121 for controlling the electrical conduction between the first side 1201 and the second side 1202.

[0075] The first busbar B1 or the second busbar B2 can be any power transmission busbar, especially for power transmission between plant equipment. For example, the first busbar B1 or the second busbar B2 can be an armored busbar, a molded busbar, or a busbar used around the case of a power distribution system. The present utility model does not limit the type of the first busbar B1 or the second busbar B2.

[0076] The first bus bar B1 or the second bus bar B2 can have parallel arranged conductor pieces with gaps between two adjacent conductor pieces. The first insertion end 11 and the second insertion end 13 can be inserted into the gaps between two adjacent conductor pieces through the insertion slots (B1S, B2S) and disposed in the gaps, thereby electrically coupled with the conductor pieces in the bus bar. Taking the combination between the first insertion end 11 and the first bus bar B1 as an example, the first insertion end 11 can be coupled to the conductor pieces of the first bus bar B1 through the insertion slot B1S and fixed to the conductor pieces of the first bus bar B1 by tightly pressing or fixing structure such as screw (for example, the fixed weight screw 114, 134). For example, the first insertion end 11 can have the fixed weight screw 114, which can adjust the distance between the conductor pieces of the first insertion end 11. When the first insertion end 11 is inserted into the insertion slot B1S, the conductor pieces of the first insertion end 11 are tightly connected with the conductor pieces in the insertion slot B1S by tightening the fixed weight screw 114; when the first insertion end 11 is to be removed, the fixed weight screw 114 can be loosened to loosen the first insertion end 11 from the insertion slot B1S. However, the way of fixing the conductor pieces of the first insertion end 11 to the conductor pieces of the first bus bar B1 is not limited to this. It should be noted that although the first insertion end 11 and the second insertion end 13 are shown as being inserted into the gaps between the conductor pieces of the first bus bar B1 and the second bus bar B2, the first insertion end 11 and the second insertion end 13 can also be inserted into the gaps between the conductor pieces of the first bus bar B1 and the second bus bar B2. Figure 1A The first bus bar B1 and the second bus bar B2 are shown as being arranged in parallel, but the relative position or angle between the first bus bar B1 and the second bus bar B2 is not limited. For example, the first bus bar B1 and the second bus bar B2 can also be arranged at right angles, and the bridge type switch 10 can be inserted into the first bus bar B1 and the second bus bar B2 by changing the arrangement angle of the first insertion end 11 and the second insertion end 13, but it is not limited to this.

[0077] The switch member 12 has a first side 1201 for inputting power and a second side 1202 for outputting 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, and the second side 1202 is then the other end of the input power. The first side 1201 of the switch member 12 and the first insertion end 11 can be electrically coupled by a conductor sheet 111 made of copper, aluminum, silver, or the like. It should be noted that the first insertion end 11 and the second insertion end 13 are only illustrative of their configurations being arranged to be coupled and matched with the first bus bar B1 and the second bus bar B2, and are not limited to the components thereof. For example, the first side 1201 of the switch member 12 can be directly inserted into the first bus bar B1 through the conductor sheet 111. In this case, the portion of the conductor sheet inserted into the first bus bar B1 is the first insertion end 11 of the utility model. On the other hand, the conductor sheet 111 can also be combined with a plug-in conductor sheet 112 arranged to be inserted into the first bus bar B1. In this case, the plug-in conductor sheet 112 is the first insertion end 11 of the utility model. Similarly, the second insertion end 13 can also be defined in the same way.

[0078] Referring to Figure 1C The conductor sheet 111 can also be sealed by a sealing shell 113 to reduce the risk of electric shock or short circuit between circuits caused by the exposure of the conductor sheet 111. Further, the sealing shell 113 can be further filled with a filling solidifying material such as epoxy resin or silicone resin. The filling solidifying material can fill the gap between the conductor sheet 111 and the sealing shell 113 before solidification, and can serve as an insulator and a rigid structure after solidification, so that the conductor sheet 111 is completely sealed in the sealing shell 113. Therefore, the filling solidifying material in the sealing shell 113 can further increase the overall waterproofness, explosion-proofness, and safety.

[0079] The switch member 12 includes a switch unit 121 that switches between a conduction state and a non-conduction state according to a control instruction to control the electrical conduction between the first side 1201 and the second side 1202. The control instruction can be mechanical, such as manually actuating a switch handle, or provided by a structure such as a spring, an electromagnet, or the like to provide a disconnection operation. The control instruction can also be a non-mechanical control instruction such as light, sound, or electricity. When the switch unit 121 is in the conduction state, the first side 1201 and the second side 1202 of the switch member 12 are in conduction with each other. At this time, the power from the first bus bar B1 can be transmitted to the second bus bar B2. Conversely, when the switch unit 121 is in the non-conduction state, the first side 1201 and the second side 1202 are not in conduction with each other. At this time, the first bus bar B1 and the second bus bar B2 cannot be electrically coupled.

[0080] By the above configuration, because the first insertion end 11 and the second insertion end 13 have sufficient safety and leakage prevention, the first insertion end 11 is configured to allow insertion into the first bus bar B1 when the first bus bar B1 is not powered off, and the second insertion end 13 is configured to allow insertion into the second bus bar B2 when the second bus bar B2 is not powered off. In addition, the switch member 12 can also be pre-set to be off to improve safety when installing the bridge switch 10, to avoid the first bus bar B1 and the second bus bar B2 from being short-circuited and other abnormal circuit states caused by operator errors. Therefore, the bridge switch 10 can be installed without being powered off (hot plug).

[0081] In an embodiment, please refer to Figure 2A The switch member 12 further includes a control unit 122 coupled to the switch unit 121 and configured to provide a control instruction CI. The control unit 122 is, for example, a computer, a microprocessor, or an FPGA with computing function. The control unit 122 receives an instruction provided by an operator or detects the current or voltage value flowing through the switch unit 121 to provide the control instruction CI to the switch unit 121, thereby controlling the on or off state of the switch unit 121.

[0082] In an embodiment, please refer to Figure 2B The switch member 12 further includes a communication unit 123 coupled to the switch unit 121 and configured to receive a signal providing the control instruction CI via 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. The communication unit 123 receives a communication signal from a remote device and provides the control instruction CI to the switch unit 121, thereby controlling the on or off state of the switch unit 121.

[0083] The control unit 122 or the communication unit 123 can make the switching of the switch unit 121 more automated and save a lot of manpower. It should be noted that Figure 2A and Figure 2B The embodiments shown in

[0084] In one embodiment, the switch unit 121 can be an air circuit breaker (ACB) or a molded case circuit breaker (MCCB). The appropriate switch unit 121 can be selected according to the amount of current transferred between the first bus bar Bl and the second bus bar B2. For example, when the amount of current is 1600 amperes or less, a molded case circuit breaker can be selected, and when the amount of current is higher, an air circuit breaker can be selected to achieve better breaking effect. In addition, compared to a molded case circuit breaker, an air circuit breaker has the advantage of being operable at a higher current, and because of its breaking principle, an air circuit breaker is easier to set up remote operation or automatic operation control means.

[0085] In one embodiment, referring to Figure 3A and Figure 3B , the bridge switch 10 further comprises a housing 14. The switch member 12 is disposed in the housing 14, and the first insertion end 11 and the second insertion end 13 are disposed outside the housing 14 and on the first face 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. In general, the housing 14 can have a door panel 141, so that the switch member 12 can be conveniently operated. The first face 1401 of the housing 14 has through holes corresponding to the first insertion end 11 and the second insertion end 13, and the through holes can allow the conductor pieces connected to the switch member 12 to pass out of the housing 14 and form or couple the first insertion end 11 and the second insertion end 13. The first face 1401 of the housing 14 is preferably selected from the face of the housing 14 opposite the door panel 141, so that when the bridge switch 10 is disposed on the first bus bar Bl and the second bus bar B2, the switch member 12 can be directly controlled by opening / closing the door panel on the front face, but is not limited thereto.

[0086] In one embodiment, referring to Figure 4The first surface 1401 of the housing 14 has at least one guiding installation structure 142 arranged according to the structure of the first busbar B1 or the second busbar B2. Specifically, the first surface 1401 of the housing 14 is a surface facing the first busbar B1 and / or the second busbar B2. When the bridge switch 10 with the housing 14 is arranged on the first busbar B1 and / or the second busbar B2, the at least one guiding installation structure 142 on the first surface 1401 can assist the installer to install along the contour or structure of the first busbar B1 and / or the second busbar B2. Through the guidance of the at least one guiding installation structure 142, the installer can arrange the bridge switch 10 with the housing 14 at the correct position. Moreover, the at least one guiding installation structure 142 can also have a snap-fit means that can be combined with the first busbar B1 and / or the second busbar B2 separately. Thus, when the bridge switch 10 with the housing 14 is arranged on the first busbar B1 and / or the second busbar B2, the at least one guiding installation structure 142 can provide the stability of the combination. The housing 14 with the guiding installation structure 142 can reduce the risk of the bridge switch 10 being detached from the first busbar B1 and / or the second busbar B2 due to vibration or accidental touch, and provide auxiliary combination force to avoid the problem of instability or loosening of the bridge switch 10 relying only on the combination force of the first insertion end 11 and the second insertion end 13 inserted into the first busbar B1 and / or the second busbar B2. It should be noted that although the at least one guiding installation structure 142 is arranged on the first surface 1401 in the embodiment, the first insertion end 11 and the second insertion end 13 of the utility model can be arranged on the same or different surfaces of the housing 14. When the first insertion end 11 and the second insertion end 13 are arranged on different surfaces, the at least one guiding installation structure 142 can be arranged on any surface of the housing 14 according to the requirement.

[0087] In an embodiment, please refer to Figure 5, the first plug-in end 11 has a first phase power terminal P1, a second phase power terminal P2 and a third phase power terminal P3; wherein the first phase power terminal P1 is coupled to the switch member 12 via a first conductor path 1111, the second phase power terminal P2 is coupled to the switch member 12 via a second conductor path 1112, and the third phase power terminal P3 is coupled to the switch member 12 via a third conductor path 1113. Specifically, the first bus bar B1 can transmit power of the same phase or different phases by adjusting the configuration within the first bus bar B1. Taking a three-phase power supply as an example, the first bus bar B1 can transmit power signals with a phase difference of 120 degrees. The first plug-in end 11 can draw different phase power signals from the first bus bar B1 through the first phase power terminal P1, the second phase power terminal P2 and the third phase power terminal P3. Different phase power signals are transmitted to the switch member 12 through the first conductor path 1111, the second conductor path 1112 and the third conductor path 1113. Similarly, the switch member 12 can control the conduction or interruption of different phase power signals transmitted by the first conductor path 1111, the second conductor path 1112 and the third conductor path 1113 to be transmitted to the second bus bar B2. Through the configuration of the present embodiment, different power supply modes can be provided according to the equipment in the factory building, so that the bridge type switch 10 can correspond to the power supply type without limitation.

[0088] In an embodiment, please refer to Figure 6 The bridge type switch 10 can also include a power meter module 15 coupled to the switch member 12, which is used to present the power data passing through the switch member 12. For example, the power meter module 15 can read the current value, power or other power parameters flowing through the switch member 12 through a current transformer or other existing power parameter reading means. And the measured value can be displayed through a display or other means. In an embodiment, the bridge type switch 10 can also include at least one indicator module 16 coupled to the switch member 12, which is used to indicate whether the switch member 12 receives power from the first bus bar B1 from the first plug-in end 11. The at least one indicator module 16 can be a light, a sound or other existing warning means, thereby providing the operator with the power status of the switch member 12.

[0089] In an embodiment, please refer to Figure 7 The first plug-in end 11 can be provided as a plurality of first plug-in ends 11, and the first bus bar B1 can also be provided with a plurality of first slots to correspond to the plurality of first plug-in ends 11. Similarly, the second plug-in end 13 can also be provided as a plurality of second plug-in ends 13, and the second bus bar B2 can also be provided with a plurality of second slots to correspond to the plurality of second plug-in ends 13. It should be noted that Figure 7The drawing is only an example and is not used to limit the number of the inserted ends and the slots in the embodiment. Through the arrangement, the current capacity that the first inserted end 11 can bear or accept can be correspondingly improved, thereby achieving the purpose of improving the current capacity of the bridging switch 10 (large-capacity bridging switch).

[0090] By connecting two or more bus bars through the bridging switch, two or more bus bars can be quickly and safely connected. The bridging switch can also be used as a circuit breaker or a circuit interruption node, so that the bus bar can set an interruption point or a safety node during power transmission to improve the safety of the overall circuit transmission, and further protect the plant equipment connected by the bus bar.

[0091] The foregoing description of the present application is provided to enable those skilled in the art to make or use the present application. Various modifications to the present application will be apparent to those skilled in the art, and the general principles defined herein can be applied to other variations without departing from the spirit or scope of the present application.
