Abstract
Description
Technical Field
[0001] The present invention relates to a switchboard system and its applicable busbar configuration, bridge switch and power distribution device; in particular, it relates to a switchboard system with a busbar configuration arranged outside a chassis. Background Art
[0002] The switchboard system uses copper bars or copper busbars to connect the power input end or the inside of the switchboard chassis. However, there are many restrictions on the use of copper bars or copper busbars. For example, the copper bars and copper busbars are insulated with air. In the high-voltage power distribution environment, the traditional switchboard system requires a large space requirement. In response to the required space requirements, a larger chassis is required, which increases the cost of the chassis. In addition, the large space requirement also means that the power transmission path is lengthened, which indirectly increases the cost of copper required for power transmission. The lengthening of the power transmission path will also cause power loss during power transmission and generate waste heat. This makes the placement space and ambient temperature of the switchboard system have considerable restrictions.
[0003] On the other hand, the connection is made through copper bars or copper bars, because copper bars or copper bars need to be bent and stretched through processing, so the power transmission path of the distribution board system is mostly customized. In other words, because copper bars or copper bars need to be processed and set, the subsequent expandability is poor. If you want to extend or change the configuration, you can only replace the original copper bars or copper bars to achieve the purpose of adjustment or expansion. In addition, the exposed copper bars or copper bars are in a high-voltage construction environment. For construction safety, it is necessary to cut off the power before construction expansion or daily maintenance. However, for high-efficiency factories, the loss of production capacity caused by power outages will be difficult to estimate.
[0004] Therefore, how to reduce the space or material cost required for the switchboard system and improve the scalability of the switchboard system as well as the convenience or safety of construction or maintenance will be a major focus of research in this field. Summary of the invention

[0016] The present invention provides a bus configuration for a switchboard system, including a first bus disposed outside a chassis of the switchboard system and coupled to a first power supply, and a second bus disposed outside the chassis. The first bus has a first setting portion, and a first setting hole corresponding to the first setting portion is provided on a wall of the chassis.

Good insulation safety also means that the required installation space can be greatly reduced, thereby reducing the required material cost and space cost. In terms of heat dissipation, since the first bus and the second bus are arranged outside the chassis, the heat energy generated by the power transmission power consumption can be effectively dissipated through the first bus and the second bus, and will not accumulate in the chassis of the switchboard system, thereby improving safety. On the other hand, the bus also has good expandability, and more than two buses can be connected through a bridge. And the bridge can also be used as a circuit breaker, so that the power transmission can set breakpoints to improve safety. BRIEF DESCRIPTION OF THE DRAWINGS

On the contrary, these names are used as a convenient way to distinguish two or more elements or element instances in this article. Therefore, it should be understood that the names "first", "second" and the like in the claims do not necessarily correspond to the same names in the written description. In addition, it should be understood that the reference to the first and second elements does not mean that only two elements can be used or that the first element must be before the second element. "Including", "including", "having", "containing" and the like used in this article are all open terms, that is, they mean including but not limited to.
[0057] The term "coupled" is used herein to refer to 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.
[0058] In the present invention, the words "exemplary" and "for example" are used to mean "used 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 present invention. The terms "approximately" and "substantially" as used herein with respect to a specified value or characteristic are intended to mean within a certain value (for example, 10%) of the specified value or characteristic.
[0059] Please refer to Figures 1A to 1C , Figures 1A to 1C The switchboard system 100 of the present invention includes a chassis 110, a bus arrangement 120 disposed outside the chassis 110, a first bridge switch 131 disposed inside the chassis 110, and a first power distribution device 141. The bus arrangement includes a first bus 121 and a second bus 122. The first bus 121 is coupled to a first power supply PW1. The first power distribution device 141 is configured to be disposed on the second bus 122. The first bridge switch 131 is configured to bridge the first bus 121 and the second bus 122.
[0060] Specifically, the chassis 110 can be made of any conventional material, such as but not limited to an iron box, a wooden box, or a plastic box. The chassis 110 has a storage space inside and a door for opening or closing the storage space. In this embodiment, the chassis 110 includes a switch box 111 at the top and a distribution box 112 at the bottom, wherein the first bridge switch 131 is disposed in the switch box 111 and the first distribution device 141 is disposed in the distribution box 112. However, Figure 1C The examples are merely examples and are not intended to limit the present invention. The chassis 110 of the present invention may also be composed of a single accommodating space or a plurality of accommodating spaces. The size of the chassis 110 may be determined, for example, based on the first power distribution device 141 and the first bridge switch 131 disposed inside. Because the bus configuration 120 responsible for external power transmission is disposed outside the chassis 110, the volume required for the chassis 110 can be greatly reduced. The manufacturing cost required for the chassis 110 is effectively reduced, and even the hidden costs such as transportation, assembly, and maintenance.
[0061] like Figure 1CAs shown, the bus configuration 120 includes a first bus 121 disposed outside the chassis 110 of the distribution board system 100 and coupled to the first power supply PW1, and a second bus 122 disposed outside the chassis 110. The first bus 121 has a first setting portion 1211, and a first setting hole 1101 corresponding to the first setting portion 1211 is provided on the box wall of the chassis 110. The second bus 122 has a second setting portion 1221 and a third setting portion, and a second setting hole 1102 corresponding to the second setting portion 1221 and a third setting hole corresponding to the third setting portion are provided on the box wall of the chassis 110 (due to the simplification of the drawing, it is not shown in the figure, please refer to the first setting portion 1211 and the first setting hole 1101). The first setting portion 1211 and the second setting portion 1221 are disposed opposite to each other and are configured for the setting of a bridge switch. The third setting portion is configured for the setting of a power distribution device. It should be noted that, Figure 1C The first and second arrangement portions 1211 and 1221 are merely examples and are not intended to limit the combination pattern of the first busbar 121 or the second busbar 122. For example, the first and second arrangement portions 1211 and 1221 may be configured for conventional busbar connection / arrangement methods such as insertion, screw locking, or pressing.
[0062] Specifically, the first busbar 121 and / or the second busbar 122 are preferably cast busbars or armored busbars with insulating shells. And the conductor sheets inside the first busbar 121 and / or the second busbar 122 are preferably filled with insulating resin to increase waterproof, dustproof or explosion-proof properties. In addition, the first busbar 121 and / or the second busbar 122 may have a thermally conductive material (e.g., thermally conductive glue or thermally conductive sheet) or a thermally conductive filling material (e.g., inorganic silicon powder or sand powder) inside, and may have a heat dissipation structure (e.g., heat dissipation fins) outside. Through the heat dissipation configuration inside and / or outside the first busbar 121 and / or the second busbar 122, the heat dissipation effect of the first busbar 121 and / or the second busbar 122 can be increased to avoid danger caused by excessive waste heat generated when transmitting high-power power.
[0063] Please refer to the layout of the bus arrangement 120 of the first bus 121 and the second bus 122. Figure 2, the bus configuration 120 is arranged outside the chassis 110 of the distribution board system 100 and preferably outside the back side of the chassis 110 (i.e., the side opposite to the chassis door), but not limited thereto. The first power supply PW1 is, for example, a transformer station or a power supply end in a factory area. After the first bus 121 receives power from the first power supply, it is transmitted to the second bus 122 through the first bridge switch 131. It should be noted that the first bridge switch 131 is arranged in the chassis 110, and is inserted into the first bus 121 and the second bus 122 through the first setting hole 1101 and the second setting hole 1102. Therefore, the first bridge switch 131 can be removably set on the first bus 121 and the second bus 122 in the chassis 110. The specific manner in which the first setting portion 1211 of the first busbar 121 and the second setting portion 1221 of the second busbar 122 are relatively set can be based on the size of the first bridge switch 131 as the basis for the spacing between the first setting portion 1211 and the second setting portion 1221. In other words, a spacing is reserved between the first busbar 121 and the second busbar 122 for the first bridge switch 131 to be inserted. In one embodiment, the first setting portion 1211 of the first busbar 121 and the second setting portion 1221 of the second busbar 122 are preferably located on the back of the switch box 111 in the chassis 110, so that the first bridge switch 131 has an independent setting space, and when the first bridge switch 131 is to be replaced or controlled, the switch box 111 can be opened to operate, thereby reducing the risk of accidental electric shock or other risks, but the effect is not limited to this.
[0064] On the other hand, the first bridge switch 131 includes a first plug-in end 1311 configured to be set on the first bus 121, a second plug-in end 1312 configured to be set on the second bus 122, and a switch portion 1313 coupling the first plug-in end 1311 and the second plug-in end 1312. The switch portion 1313 is used to control the conduction of the first plug-in end 1311 and the second plug-in end 1312. Specifically, the first plug-in end 1311 and the second plug-in end 1312 of the first bridge switch 131 can have corresponding plug-in interfaces according to the corresponding first setting portion 1211 and the second setting portion 1221. The switch portion 1313 of the first bridge switch 131 can switch between passage and disconnection. When the switch portion 1313 is passage, the first plug-in end 1311 and the second plug-in end 1312 will be electrically conductive. When the switch portion 1313 is disconnected, there will be no conduction between the first plug-in end 1311 and the second plug-in end 1312. Generally speaking, the first bridge switch 131 can also be used as a circuit breaker. For example, the type of the first bridge switch 131 can be selected from a molded case circuit breaker (MCCB), an air circuit breaker (ACB) or other circuit breakers or switches with existing breaking mechanisms. By connecting the first bus 121 and the second bus 122 through the first bridge switch 131, the first line protection function can be achieved. And when the first bus 121 or the second bus 122 has multiple sets of bridge switches in parallel, independent disconnection can also be performed. However, in the architecture of the present invention, the first bus 121 can also be directly coupled to the second bus 122 without being isolated by the first bridge switch 131. It should be noted that, Figure 2 The horizontal arrangement of the bus configuration 120 shown in the figure is only an example and is not intended to limit the present invention. In the present invention, the first bus 121 and the second bus 122 can be arranged horizontally, vertically or diagonally. The layout of the first bus 121 and the second bus 122 can be adjusted according to the setting environment, the power supply direction or other existing configuration considerations.
[0065] The second bus bar 122 preferably extends to the distribution box 112 and has a third installation portion for the first distribution device 141 to be inserted. In this way, the first distribution device 141 can be installed in the distribution box 112. For details, please refer to Figure 3A and Figure 3B, the first power distribution device 141 includes a third plug-in terminal configured to be set on the second bus 122 and a power distribution structure. Specifically, the second bus 122 can have a third setting portion, and the first power distribution device 141 can be set on the third setting portion of the second bus 122 via the third plug-in terminal. The third plug-in terminal and the third setting portion can be, for example, a connection means for a conventional bus. The power distribution structure is coupled to the third plug-in terminal. When the first power distribution device 141 is set on the second bus 122 and the first bridge switch 131 is turned on, the power of the first power supply PW1 can be transmitted to the power distribution structure. The power distribution structure can be, for example, as follows Figure 3A The connection line structure is shown or Figure 3B The structure of a power distribution strip is shown. In the embodiment of the connecting line structure, the device E requiring power can be coupled via a power transmission line. It should be noted that the power transmission line can be fixedly or detachably coupled to the third plug-in terminal (for example, through connection means such as a plug and a socket), and the power transmission line can be connected to a single device or multiple devices according to parameters such as power demand and power. On the other hand, in the embodiment of the power distribution strip structure, the power distribution strip structure can be configured to provide multiple branching devices 151 to lead out power and transmit it to the device E after being plugged in. It should be noted that the present invention is not limited to the number of power distribution devices. In other words, the second bus 122 can provide multiple plug-in positions for multiple power distribution devices to be plugged in, and in the embodiment of multiple power distribution devices, it is not limited to the type of power distribution devices. Figure 3A and Figure 3B The power distribution structures in the illustrated embodiments may be implemented separately or in combination.
[0066] In one embodiment, please refer to Figure 4 , the first power distribution device 141 may also include a main control switch 1411. For example, the primary side of the main control switch 1411 may be coupled to the third plug-in terminal 1412, and the secondary side of the main control switch may be coupled to the power distribution structure 1413. Specifically, the primary side of the main control switch 1411 is the side of the power input, which may be coupled to the second bus 122 through the third plug-in terminal 1412 and receive power from the first power supply PW1. After the main control switch 1411 performs circuit-breaking protection, the power distribution structure 1413 coupled to the secondary side of the main control switch 1411 (i.e., the side coupled to the load) is used for power distribution. In this way, an extra layer of protection may be provided to the first power distribution device 141, and when there are multiple power distribution devices, the main control switches of the power distribution devices may control the power distribution devices, thereby achieving the purpose of independent operation. However, the power distribution device of the present invention is not limited to the main control switch, and the power transmission control may also be switched only through the first bridge device.
[0067] The copper bus or copper bar connected to the power supply in the conventional switchboard system 100 is replaced by the first bus 121 and the second bus 122 arranged outside the chassis 110. Compared with the copper bus or copper bar, the first bus 121 and the second bus 122 can have better insulation because they adopt armored or die-cast bus, and do not require a large space for air insulation. Therefore, the occupied volume can be reduced, and the better insulation can also provide a safe construction environment, and can be installed or removed without cutting off the power supply. In addition, the conductor volume / length required for the bus is relatively small, so the material cost can be saved and the power loss on the power transmission path can be reduced. On the other hand, the bus also has good expandability, and more than two buses can be connected through a bridge. And the bridge can also be used as a circuit breaker, so that the power transmission can set a breakpoint to improve safety. The bus configuration installed outside the chassis also has a good heat dissipation effect, preventing heat from accumulating inside the chassis and causing risks in the power usage environment. It can also reduce the operating costs of constantly monitoring the temperature of the distribution board.
[0068] In one embodiment, please refer to Figure 5 The switchboard system 100 may further include a third busbar 123 disposed outside the chassis 110 and a second bridge switch 132 disposed inside the chassis 110. The third busbar 123 is coupled to the second power supply PW2. The second bridge switch 132 is configured to bridge the third busbar 123 and the second busbar 122.
[0069] Specifically, the third bus 123 coupled to the second power supply PW2 can be connected to the first bus 121 coupled to the first power supply PW1 as a dual-circuit parallel power supply. For example, when the first bridge switch 131 turns on the first bus 121 and the second bus 122 and the second bridge switch 132 is disconnected, the first power distribution device 141 will receive power from the first power supply PW1. When the power supply of the first power distribution device 141 is to be switched, the second bridge switch 132 can be set as a passage to turn on the second bus 122 and the third bus 123, and the first bridge switch 131 can be turned off. At this time, the first power distribution device 141 will receive power from the second power supply PW2. In this way, when one of the first power supply PW1 or the second power supply PW2 is abnormal or needs to be interrupted, the power supply of the first power distribution device 141 can be quickly switched to avoid the loss of interruption of factory machine operation due to the need to wait too long.
[0070] In one embodiment, please refer to Fig. 6A , Figure 6B and Figure 7The switchboard system 100 further includes a third bus 123 disposed outside the chassis 110, a fourth bus 124 disposed outside the chassis 110, a second bridge switch 132 disposed inside the chassis 110, and a third bridge switch 133 disposed inside the chassis 110. The third bus 123 is coupled to the second power supply PW2. The second bridge switch 132 is configured to bridge the third bus 123 and the fourth bus 124. The third bridge switch 133 is configured to bridge the second bus 122 to the third bus 123 or the fourth bus 124. It should be noted that Fig. 6A and Figure 6B The second busbar 122 and the fourth busbar 124 in the busbar configuration 120 are partially connected to each other, which can increase the structural strength and integrity. However, the layout of the internal conductors in the busbar configuration 120 is shown in FIG. Figure 7 .
[0071] Specifically, the third bus 123 coupled to the second power supply PW2 can be connected to the first bus 121 coupled to the first power supply PW1 as a dual-circuit parallel power supply, and coupled to the remaining power distribution devices (for example, the second power distribution device 142) through the fourth bus 124. It can be achieved that the first power supply PW1 can provide power to the first power distribution device 141 via the first bus 121 and the second bus 122 (through the first bridge switch 131 being turned on), and at the same time, the second power supply PW2 can provide power to the second power distribution device 142 via the third bus 123 and the fourth bus 124 (through the second bridge switch 132 being turned on). In this way, a dual-circuit dual power supply architecture is achieved. It should be noted that in the above dual power supply condition, the third bridge switch 133 is in an open circuit state to prevent the first power supply PW1 and the second power supply PW2 from short-circuiting each other.
[0072] When it is necessary to switch the dual-circuit parallel power supply, the second bus 122 can be bridged to the fourth bus 124 through the third bridge switch 133. For example, when the first power distribution device 141 is required to receive power from the second power supply PW2, the third bridge switch 133 is set to a passage so that the second bus 122 and the third bus 123 are connected to each other, the second bridge switch 132 is also set to a passage so that the third bus 123 and the fourth bus 124 are connected to each other, and the first bridge switch 131 is set to an open circuit so that the first bus 121 and the second bus 122 are not connected to each other. On the other hand, when the second power distribution device 142 is required to receive power from the first power supply PW1, the third bridge switch 133 is set as a passage to make the second bus 122 and the fourth bus 124 conduct to each other, and the first bridge switch 131 is also set as a passage to make the first bus 121 and the second bus 122 conduct to each other, and the second bridge switch 132 is set to be disconnected to make the third bus 123 and the fourth bus 124 not conduct to each other. Through the above-mentioned bus configuration 120, the first power supply PW1 and the second power supply PW2 can be independently powered and can support each other. And the bus configuration 120 is set outside the chassis 110, which can effectively reduce the volume required for the chassis 110 and the length of the transmission line. When expansion is required, it is only necessary to appropriately extend or transfer the bus, and there will be no problem of difficulty in adjustment when the traditional copper bus or copper bar configuration is encountered.
[0073] In this embodiment, the number of the first power distribution devices 141 or the second power distribution devices 142 is not limited. Figure 8 , the second bus 122 can extend (and preferably be bent and extended) in the chassis 110 (for example, the distribution board box 112), and have a plurality of third setting parts for the plurality of first distribution devices 141 to be plugged in. On the other hand, the fourth bus 124 can also have a plurality of setting parts for the plurality of second distribution devices 142 to be plugged in. It should be noted that the number of the third setting parts of the second bus 122 can be greater than or equal to the number of the first distribution devices 141. Specifically, more third setting parts can be used as reserve setting parts to make the setting of the first distribution device 141 more flexible and elastic.
[0074] Based on the above bus configuration (i.e., the first bus, the second bus, the third bus, and the fourth bus) set outside the chassis and combined with a bridge switch, a dual-circuit parallel power supply application can be achieved. In addition, the bus configuration set outside the chassis can save volume due to its better insulation and heat dissipation. In addition, compared with copper busbars, the expansion and change of the bus are more flexible. When a bridge switch or a power distribution device is inserted into the bus configuration, a non-stop power setting (hot plug) can be achieved due to higher safety.
