[0044] Figure 1 This is a block diagram of a high-power power distribution system 100. The power distribution system 100 delivers power from a power source 101 to an electrical load 102 via a distribution path 106. The distribution path 106 may include, for example, one or more distribution lines, cables, and / or any other means for transmitting power. The power distribution system 100 may be, for example, a power grid, an electrical system, or a multiphase electrical network that provides power to commercial and / or residential customers. The power distribution system 100 may have an operating voltage, for example, at least 1 kV, up to 34.5 kV, up to 38 kV, up to 69 kV, or 69 kV or higher. The power distribution system 100 is an alternating current (AC) electrical network and may operate at a base frequency of, for example, 50 Hz to 60 Hz.

[0045] The power distribution system 100 includes a switching device 110. Device 110 includes a body 120 encapsulating a switch 112. Switch 112 is any type of device capable of interrupting power supply to an electrical load 102. The rated voltage of switch 112 can be, for example, between 15kV and 38kV, between 15kV and 30kV, greater than 15kV, 15kV, or 29.2kV. The rated continuous current of switch 112 can be, for example, between 100 amperes (A) and 600A, or between 100 and 200A. Switch 112 is capable of interrupting fault currents, for example, 1kA to 10kA, 1kA to 4kA, 1kA to 7kA, or 6.3kA. Switch 112 can be, for example, a switch capable of repeated opening and closing, such as a vacuum interrupter or a solid-state device. Other types of devices capable of interrupting and conducting current but not necessarily capable of repeated opening and closing, such as fuses, can be used as switch 112. In embodiments where switch 112 is a vacuum interrupter or other switch capable of being repeatedly opened and closed, device 110 is a recloser and may be a single-phase solid dielectric recloser.

[0046] Switch 112 includes an associated component 113. In embodiments where switch 112 is a vacuum interrupter and device 110 is a recloser, the associated component 113 may include actuating devices to cause the contacts of vacuum interrupter 112 to open and close, and includes electronics for controlling these actuating devices and for communicating with remote station 199. Remote station 199 may be, for example, a remote control or a remote laptop computer or other computing device.

[0047] The main body 120 is physically connected to or mounted to the mounting structure 140. Specifically, the main body 120 is mechanically connected to the lower portion 141 of the mounting structure 140 via a first mounting assembly 150, and the main body 120 is mechanically connected to the upper portion 142 of the mounting structure 140 via a second mounting assembly 170. The first mounting assembly 150 and the second mounting assembly 170 provide a variety of mounting options and increase the usability of the device 110. For example, the first mounting assembly 150 and the second mounting assembly 170 allow the main body 120 to be mounted to various types of mounting structures, such as insulated mounting brackets, which may be fuse interrupters, fuse-less interrupters, or visible disconnect mounting brackets. This allows for standardization of end-user inventory and installation procedures and improves the ease of use and efficiency of the device 110.

[0048] Switch 112 is electrically connected to a first terminal 122 and a second terminal 124 via an electrical connection 129. In an embodiment where switch 112 is a vacuum interrupter, the electrical connection 129 includes an actuator and an operating lever for opening and closing the electrical contacts of switch 112. The first terminal 122 and the second terminal 124 are made of a conductive material, such as copper, a copper alloy, or any other metallic material. The body 120 is a three-dimensional object extending from a first end 126 to a second end 128. Figure 1 In the example, a second terminal 124 extends from a second end 128 of the body 120, and a first terminal 122 extends from a first end 126 of the body 120. The second terminal 124 may extend through a second opening in the body 120, and the first terminal 122 may extend through a first opening in the body 120. The body 120 is made of an electrically insulating material, such as ceramic, a robust polymer, or any other suitable electrically insulating material. The body may or may not include an insulating baffle.

[0049] In the example shown, the second terminal 124 is electrically connected to the power supply 101, and the first terminal 122 is electrically connected to the electrical load 102. However, in other embodiments, the second terminal 124 is electrically connected to the electrical load 102, and the first terminal 122 is electrically connected to the power supply 101.

[0050] Electrical load 102 is any device or equipment that utilizes electricity, and may include electrical equipment that receives and transmits or distributes electricity to other equipment in the power distribution system 100. Electrical load 102 may include, for example, transformers, switching equipment, energy storage systems, computer and communication equipment; lighting, heating and air conditioning; motors and electrical mechanisms in manufacturing facilities; and / or electrical appliances and systems in residential buildings. Power source 101 is any source of electricity, such as a power plant that generates electricity from fossil fuels or from thermal energy or a transformer. Power source 101 may include one or more distributed energy sources, such as a solar energy system comprising an array of photovoltaic (PV) devices that convert sunlight into electricity or a wind-based energy system. More than one power source may supply power to the power distribution system 100, and more than one type of power source may supply power to the power distribution system 100.

[0051] Under normal and desired operating conditions, switch 112 is closed. Current flows through switch 112 and is delivered to electrical load 102. In the presence of fault conditions (e.g., current and / or voltage exceeding the safe operating parameters of electrical load 102), switch 112 opens to interrupt the power supply to electrical load 102. In embodiments where switch 112 is a recloser, switch 112 may be closed and reopened multiple times before locking and holding open in an attempt to clear the fault.

[0052] refer to Figure 2 , Figure 3 , Figures 4A to 4G and Figures 5A to 5F Various implementations of the first mounting component 150 and the second mounting component 170 will be discussed below. Figures 6 to 8 Various embodiments of switchgear with dual-mount or universal mounting systems are shown.

[0053] Figure 2 This is a side block view of device 210. Device 210 is a derivative of device 110. Figure 1 The device 210 includes a body 220 encapsulating a switch 112. The switch 112 is electrically connected to a source terminal 224 extending from a second end 228 of the body 220 and to a load terminal 222 near a first end 226 of the body 220. The source terminal 224 is configured to be electrically connected to a source (such as...) Figure 1 The power supply 101). Load terminal 222 is configured to be electrically connected to a load (such as...). Figure 1 The electrical load 102). The body 220 is a three-dimensional object and may be, for example, substantially cylindrical in shape. The body 220 includes a plurality of insulating baffles 221, each extending outward from an outer surface 227 in the XY plane. The body 220 includes a base 280 (or housing 280) at a first end 226. The base 280 is attached to an operating handle 281. The operating handle 281 is coupled to a switch 112 and allows the switch to be manually turned on or off from outside the body 220.

[0054] The main body 220 is mounted to the circuit breaker 240 via the first mounting component 250 and the second mounting component 270, which will be discussed further below.

[0055] exist Figure 2 In the example, the circuit breaker 240 is a circuit breaker having a substantially U-shape or C-shape in the YZ plane. The circuit breaker 240 is made of an electrically insulating material. For example, the circuit breaker 240 may be made of ceramic or an insulating polymer. The circuit breaker 240 includes an upper portion 242 and a lower portion 241. An intermediate portion 243 extends between the upper portion 242 and the lower portion 241. An insulating baffle 245 extends vertically from the intermediate portion 243. The intermediate portion 243, the upper portion 242, and the lower portion 241 are joined together or made from a single continuous piece of insulating material, such that the circuit breaker 240 is a monolithic piece (e.g., ceramic with a metal insert or a polymer overlaid on metal or glass fiber). The circuit breaker 240 also includes a mounting mechanism 244 extending along the Y direction from the intermediate portion 243. The mounting mechanism 244 allows the circuit breaker 240 to be attached to a separate structure, such as a utility pole or crossarm.

[0056] The first mounting assembly 250 connects the load terminal 222 to the lower portion 241 of the circuit breaker 240. The second mounting assembly 270 connects the source terminal 224 to the upper portion 242 of the circuit breaker 240. The first and second mounting assemblies 250 rigidly attach the body 220 to the circuit breaker 240, preventing movement of the body 220 relative to the circuit breaker 240. The body 220 will not detach from the circuit breaker 240. Therefore, the relatively complex connection points that traditionally allow the body to detach from the circuit breaker are unnecessary. This results in lower cost and a simpler design. Furthermore, this rigid connection ensures good electrical contact at terminals 222 and 224. Additionally, the rigid mounting assemblies 250 and 270 can be used in retrofit kits to adapt a rod-mount design to the circuit breaker 240. Figures 6 to 8 An example of a pole-mounted design is shown in the figure.

[0057] The first mounting assembly 250 includes a first connecting portion 251, a first connecting plate 252, a second connecting plate 253, and a second connecting portion 256. The first connecting portion 251 is connected to the load terminal 222. Figure 2 In the example, load terminal 222 is a ring assembly having a circular cross-section in the XY plane. The ring assembly includes threaded openings or holes 223, either of which can receive the threaded terminal connection end 254 of the first connection portion 251.

[0058] The load terminal 222 may include six openings 223, each spaced apart from the others by, for example, about 60 degrees. Other configurations of the ring assembly are also possible. For example, the ring assembly may include more or fewer than six openings 223. The openings 223 may be adapted to be spaced apart in any configuration of this application. For example, the openings 223 may be unevenly spaced.

[0059] A first connecting plate 252 is attached to the second end 255 of the first connecting portion 251. The first connecting plate 252 is perpendicular to the first connecting portion 251, and the first connecting portion 251 is attached to the first connecting plate 252 at or near the center of the first connecting plate 252. Figure 2 In the example shown, the body 220 extends along the Z direction, and when the first connecting portion 251 is connected to the load terminal 222, the first connecting portion 251 extends along the Y direction, and the first connecting plate 252 extends along the Z direction. The first connecting plate 252 and the first connecting portion 251 may be two pieces permanently attached to each other by, for example, fusion, brazing, or welding. In some embodiments, the first connecting plate 252 and the first connecting portion 251 are formed from a single piece.

[0060] The second connecting plate 253 is a plate-like structure attached to the second connecting portion 256. The first and second connecting plates have substantially flat surfaces 265 and 266 extending in the XZ plane. The end portion 257 of the second connecting portion 256 is attached to the end region 258 of the second connecting plate 253. The second connecting portion 256 extends from the end region 258 at an angle 259. The angle 259 is less than 90 degrees (°). The second connecting plate 253 and the second connecting portion 256 may be formed from permanently joined separate pieces, or the second connecting plate 253 and the second connecting portion 256 may be formed from a single piece of material.

[0061] To engage the load terminal 222 to the lower portion 241 of the circuit breaker 240, the threaded terminal connection end 254 of the first connecting portion 251 is screwed into one of the openings 223 in the load terminal 222. The first connecting plate 252 and the second connecting plate 253 are positioned with their respective surfaces 265 and 266 facing each other. The plates 252 and 253 are mounted to each other by fasteners 264 (such as screws).

[0062] The second connecting portion 256 extends away from surface 266. The second connecting portion 256 includes an opening 260 (shown in dashed lines), and the lower portion 241 also includes an opening 246 (shown in dashed lines). When the first connecting portion 251 is connected to the load terminal 222 and the first connecting plate 252 is connected to the second connecting plate 253, the opening 260 aligns with the opening 246. A fastener 262 passes through the openings 246 and 260 to connect the second connecting portion 256 to the lower portion 241. The fastener 262 may include a screw passing through the openings 246 and 260 and is secured by a nut.

[0063] Also refer to Figure 3 The diagram illustrates a first mounting assembly 350. The first mounting assembly 350 is another embodiment of the first mounting assembly 250. The first mounting assembly 350 can be used with the body 220 in place of the first mounting assembly 250. The first mounting assembly 350 includes a first connecting portion 351, a second connecting portion 352, and a third connecting portion 353. The first mounting assembly 350 is a single piece and includes fewer parts than the first mounting assembly 250. Therefore, the first mounting assembly 350 is easier to manufacture than the first mounting assembly 250.

[0064] The first connecting portion 351 includes a threaded end portion 354 (shown in shaded area) configured to connect to an opening in a threaded opening 223 in the load terminal 222. A second connecting portion 352 connects to an end 355 of the first connecting portion 351. End 355 is opposite to end portion 354. The second connecting portion 352 extends perpendicularly to the first connecting portion 351 to an end 358. A third connecting portion 353 engages with the second connecting portion 352 at end 358. The third connecting portion 353 extends relative to the second connecting portion 352 at an angle 359. Angle 359 is less than 90°. When the threaded end portion 354 is connected to the threaded opening in the load terminal 222, the first connecting portion 351 extends in the Y direction, and the second connecting portion 352 extends in the Z direction. The third portion 353 includes an opening 360. The third portion 353 is attached to the lower portion 241 by passing a fastener 262 through and securing the fastener 262 to the openings 360 and 246.

[0065] Refer again Figure 2 Regardless of which implementation of the first mounting assembly is used, both the first mounting assembly 250 and the first mounting assembly 350 rigidly secure the lower portion 241 of the circuit breaker 240 to the body 220. Neither the first mounting assembly 250 nor the first mounting assembly 350 permits the body 220 to rotate in the YZ plane or otherwise move relative to the circuit breaker 240.

[0066] The second mounting assembly 270 includes a one-piece connection portion 271. The connection portion 271 includes a first region 272 and a second region 273 angled relative to the first region 272. The first region 272 and the second region 273 are substantially flat. The angle between the first region and the second region 273 is greater than 90°. The first region 272 includes an opening 276 for receiving a source terminal 224. The second region 273 includes an opening 275, and the upper portion 242 includes an opening 247. When the connection portion 271 is attached to the source terminal 224, and the first mounting assembly 250 connects the load terminal 222 to the lower portion 241 of the circuit breaker 240, the opening 247 aligns with the opening 275. A fastener 249 passes through the openings 275 and 275 to secure the connection portion 271 to the upper portion 242 of the circuit breaker 240. Thus, the second mounting assembly 270 physically attaches the second end 228 of the body 220 to the upper portion 242 of the circuit breaker 240.

[0067] After the body 220 is attached to the circuit breaker 240 using the first mounting component 250 (or 350) and the second mounting component 270, the body 220 remains attached to the circuit breaker 240 until the fasteners 249 and 262 are intentionally removed. In other words, the first mounting component 250 (or 350) and the second mounting component 270 hold the body 220 in a fixed position within the circuit breaker 240, preventing the body 220 from moving relative to the circuit breaker.

[0068] Figure 4A and Figure 4B This is a side block view of device 410. Device 410 is a derivative of device 110. Figure 1 Another implementation of ). Figure 4A The device 410 is shown in a locked state. Figure 4B The device 410 is shown in the released state.

[0069] Device 410 includes a main body 220, a load terminal 222, a source terminal 224, and a circuit breaker 240. The source terminal 224 is connected to a rod structure 425. The rod structure 425 extends into and out of... Figure 4A and Figure 4B The page in the document. Device 410 includes a first mounting assembly 450 and a second mounting assembly 470. Mounting assemblies 450 and 470 mount the body 220 to the circuit breaker 240.

[0070] Mounting assembly 450 includes a connecting portion 451, a spring-loaded cam retainer 452, and a release lever 453. The connecting portion 451 and the release lever 453 are made of a rigid material, such as metal or a strong plastic. The spring-loaded cam retainer 452 is made of a strong but flexible material. For example, the spring-loaded cam retainer 452 may be made of a relatively thin metal piece. Figures 4C to 4E Various aspects of the mounting component 450 are shown. Figure 4C This is a side view of the connecting part 451. Figure 4D This is a view of the connecting part 451 in the XY plane. Figure 4E Perspective view of release lever 453.

[0071] Release lever 453 includes an arm 457 extending from a first end 458 to a second end 459. Figure 4E The first end 458 is mounted to the base 280 at pivot point 483. The arm 457 is rotatable about pivot point 483 in the YZ plane. The release lever 453 also includes a lever 456 at the second end 459. The lever 456 extends perpendicular to the arm 457.

[0072] The connecting portion 451 is a rigid member connected to the lower portion 241 of the circuit breaker 240. The connecting portion 451 includes an opening 460. Fasteners 262 pass through the openings 460 and 246 (located on the circuit breaker 240) to secure the connecting portion 451 to the lower portion 241 of the circuit breaker 240.

[0073] A spring-loaded cam retainer 452 is attached to the connecting portion 451 by a fastener 464. The spring-loaded cam retainer 452 includes a hook portion 454. See also... Figure 4D The connecting portion 451 and the hook portion 454 are substantially U-shaped in the XY plane, such that there is an open central region 462 in the connecting portion 451.

[0074] Also refer to Figure 4F and Figure 4G The second mounting component 470 includes a pivot body 471. Figure 4F A cross-sectional view of the pivot body 471 in the YZ plane is shown. Figure 4G A side view of the pivot body 471 in the XY plane is shown. Figure 4G In the diagram, the hidden lines are shown in a dashed pattern. The pivot body 471 includes a first portion 475, a second portion 476, and a groove 477 between the first portion 475 and the second portion 476.

[0075] A hole 474 extends from the side 478 into the second portion 476 of the pivot body 471. The hole 474 is aligned with the opening 247 of the upper portion 242 of the circuit breaker 240. The pivot body 471 is secured to the upper portion 242 by passing a bolt or screw through the opening 247 in the upper portion 242 of the circuit breaker 240 and into the hole 474.

[0076] Slot 479 ( Figure 4G An opening is provided through the first portion 475 to the recess 477. The slot 479 and recess 477 are sized to receive and secure the source terminal 224 and the rod structure 425, respectively. The source terminal 224 and rod structure 425 are aligned along arrow 485 (…). Figure 4F Move and place it into groove 477 and slot 479. Figure 4G The source terminal 224 in slot 479 and the rod structure 425 in groove 477 are shown.

[0077] Refer again Figure 4A When the body 220 is attached to the circuit breaker 240, the rod 456 of the release lever 453 engages the outside of the hook portion 454, and the arm 457 is located in the open area 462. Figure 4D In order to release the main body 220 from the circuit breaker 240, the release lever 453 is rotated about the pivot point 483 until the lever 456 clears the hook portion 454. See again. Figure 4F and Figure 4G When the first end 226 of the body 220 is not connected to the circuit breaker 240, the rod structure 425 rotates in the groove 477 (of the second mounting assembly 270), and the load terminal 222 and the body 220 rotate or pivot in the YZ plane, so that the first end 226 of the body 220 moves away from the circuit breaker 240. Figure 4B This condition is illustrated. By pressing the body 220 at push point 488, the body 220 can be pushed back into the circuit breaker 240, causing the release lever 453 to re-engage the hook portion 454. Push point 488 can be configured to engage with a live operating lever, allowing the operator to push the body 220 into the circuit breaker 240 from a safe and / or convenient position.

[0078] Therefore, mounting assemblies 450 and 470 allow the first end 226 of the body 220 to swing away from the lower portion 241 of the circuit breaker 240, while the source terminal 224 remains attached to the upper portion 242 of the circuit breaker 240. Mounting assemblies 450 and 470 improve the overall efficiency and ease of use of the device 410. For example, the body 220 can be more easily mounted into the circuit breaker 240 using a live operating lever, as the live operating lever is pushed below the center of gravity of the body 220. Furthermore, mounting assemblies 450 and 470 can be used as part of a retrofit to adapt a device originally designed for lever mounting to a device capable of being mounted into a circuit breaker.

[0079] Figure 5A A side view of the device 510 in the locked state. Figure 5B This is a side view of device 510 in the released state. Device 510 is another embodiment of device 410. Device 510 includes a body 220, terminals 222 and 224, and a rod structure 425. Device 510 also includes a first mounting assembly 550 and a second mounting assembly 570, and a connection portion 551 that connects to an opening in an opening 223 on the load terminal 222. The first mounting assembly 550 and the second mounting assembly 570 connect the body 220 to the insulating mounting structure 540. When the first mounting assembly 550 is locked ( Figure 5A The end 555 of the connecting portion 551 is secured in the loop region 557 by a release mechanism 553. When the first mounting assembly 550 is released (such as...), Figure 5B As shown), the rod structure 425 and the body 220 rotate in the YZ plane, and the first end 226 of the body 220 swings away from the insulating mounting structure 540.

[0080] Figure 5C and Figure 5D These are the front view and side view of the second mounting component 570, respectively. Figure 5E The first mounting component 550 is shown in the locked position. Figure 5FA first mounting assembly 550 in the released position is shown. A second mounting assembly 570 includes a connecting portion 571 extending from a first end 572 to a bent end 573. The first end 572 is attached to an upper portion 542 of an insulating mounting structure 540. The first end 572 can be attached to the upper portion 542 using, for example, bolts or other fasteners. The connecting portion 571 extends from the first end 572 and bends or tilts slightly downward (along the -Z direction) and then bends upward (along the Z direction) to the bent end 573. The connecting portion 571 is a track having an open central region 574. A terminal 424 is fitted in the open region 574, and the bent end 573 holds the rod structure 425. When the first mounting assembly 550 is released, the rod structure 425 is held by the bent end 573, and the rod structure 425 and the body 220 rotate in the YZ plane.

[0081] refer to Figure 5E The first mounting assembly 550 includes a loop region 557, a friction track 552, and a release mechanism 553. The loop region 557 forms a semi-circular opening at the lower portion 541 of the insulating mounting structure 540. In the locked position ( Figure 5A and Figure 5E In the circuit, release mechanism 553 holds end 555 of connection portion 551 within loop region 557. Release mechanism 553 holds end 555 in the locked state. Figure 5A and Figure 5E ), and releases the end 555 in the release state ( Figure 5B and Figure 5F The release mechanism 553 may be, for example, a latch or a hinged retainer, which engages the end 555 in the locked state such that the end 555 is held in the loop region 557. In the released state, the release mechanism 553 moves out of the path of the end 555 to allow the end 555 to move along the friction track 552 and out of the loop region 557.

[0082] After the release mechanism 553 is in the released state, as the lever structure 425 and the body 220 rotate in the YZ plane, the end 555 moves along the friction track 552. The friction track 552 inhibits or prevents the movement of the end 555 (and therefore also prevents the movement of the body 220). By preventing this movement, the friction track 552 eliminates or reduces the possibility of overshoot. Furthermore, by preventing this movement, the friction track also eliminates or reduces the possibility of the body 220 unintentionally swinging back to the locked position. Therefore, the friction track 552 also protects the switch 112 and component 113 from electric shock and damage. Furthermore, in Figure 5A and Figure 5B In the illustrated embodiment, the device 510 can fall onto the connecting portion 571 and will land on the friction track 552. Therefore, Figure 5A and Figure 5BThe configuration shown improves the efficiency of installing and replacing device 510.

[0083] Any of the aforementioned mounting components 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 can be used to connect switchgear, such as connecting a single-phase recloser to an insulated mounting bracket. Furthermore, any of the aforementioned mounting components 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 can be used with switchgear configured to connect to utility structures or insulated mounting brackets. Utility structures are large structures in an electrical distribution system that are typically intended to be permanent. Examples of utility structures include wooden utility poles, any other type of large pole, or concrete structures.

[0084] refer to Figure 6 and Figure 7 Any of the above mounting components 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 can be used with Figure 6 The switch device 610 shown or Figure 7 The switchgear 710 shown is used together. Specifically, any of the aforementioned mounting components 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 can be used to connect switchgear 610 or switchgear 710 to an insulating mounting bracket. This insulating mounting bracket can be a fuse interrupter mounting bracket. As described below, switchgear 610 and 710 can also be attached to utility structures. Therefore, switchgear 610 and 710 have dual mounting or universal mounting capabilities.

[0085] Figure 6 A side view of the switchgear 610 is shown. The switchgear 610 includes a grounding box 680 or a base 680. The switchgear 610 includes an upper housing 620A and a lower housing 620B. The upper housing 620A and the lower housing 620B are three-dimensional objects made of electrically insulating material. The upper housing 620A and the lower housing 620B include insulating baffles 621 extending radially outward from the bodies 620A and 620B. The baffles 621 are used to increase the withstand voltage of the switchgear 610, enabling the switchgear 610 to withstand faults while maintaining its installation on a utility structure.

[0086] The upper housing 620A extends along the Z direction from the first end 626A to the second end 628A. A second electrical terminal 624 extends through the second end 628A of the upper housing 620A. A load terminal 222 is attached to the first end 626A. The load terminal 222 and the second electrical terminal 624 are electrically connected to a switch (not shown) inside the upper housing 620A. This switch is similar to the switch 112 described above.

[0087] The lower housing 620B extends along the Z direction from the first end 626B to the second end 628B. The second end 628B is mounted to the load terminal 222. The first end 626B is mounted to the enclosure 680. The lower housing 620B provides electrical isolation between the load terminal 222 and the enclosure 680, and the enclosure 680 is a grounded enclosure.

[0088] Box 680 includes a mechanical interface 689 configured to attach box 680 to a utility structure. Figure 6 In the example shown, mechanical interface 689 is a connection point on the outer surface 691. Mechanical interface 689 connects to rigid support 693. Rigid support 693 extends from a first end 694 to a second end 695. Rigid support 693 is any rigid body capable of supporting the switching device 610 and securing it to the utility structure. Because the housing 680 is grounded, the rigid support can be made of a conductive material. For example, rigid support 693 can be a steel bracket or a bracket made of another metallic material. Rigid support 693 can be made of an electrically insulating material, such as a robust polymer that may or may not include an insulating baffle.

[0089] The first end 694 is connected to the mechanical interface 689 via a temporary but robust attachment mechanism 696. Mechanism 696 is robust enough to secure the rigid support 693 to the mechanical interface 689. Furthermore, attachment mechanism 696 allows the rigid support 693 to be removed from the mechanical interface 689 without damaging the mechanical interface 689, the housing 680, or the rigid support 693. Attachment mechanism 696 can be, for example, a screw and corresponding hole, a block or post and corresponding opening, or any other mechanical fastener. Attachment mechanism 696 allows the rigid support 693 to be repeatedly attached to and removed from the housing 680, for example, along path L.

[0090] This configuration allows the switchgear 610 to be easily converted into a switchgear that can be mounted on insulating mounting brackets (with mounting assemblies 150 and 170, 250 (or 350)) and 270, 450 and 470, or 550 and 570) and a switchgear that can be mounted on utility structures. Therefore, the usability of the switchgear 610 is enhanced, and end users achieve cost and time savings.

[0091] Figure 7 This is a side view of the switching device 710. The switching device 710 includes a housing 720 extending from a first end 726 to a second end 728. The housing 720 is a three-dimensional body made of an electrically insulating material. An insulating baffle 721 extends outwardly from the outer surface of the housing 720. The first end 726 is attached to a load terminal 222, and a terminal 724 extends through the second end 728. The housing encloses the switch (…). Figure 7(Not shown, but similar to switch 112). This switch is electrically connected to terminals 724 and 722.

[0092] The switchgear 710 includes a housing 780 coupled to a load terminal 222. The housing 780 is not grounded. The housing 780 includes a mechanical interface 789 configured to attach the housing 780 to a utility structure. The mechanical interface 789 connects to a rigid support 793. The rigid support 793 extends from a first end 794 to a second end 795. Because the housing 780 is not grounded, the rigid support 793 is made of an electrically insulating material and may include insulating baffles. The rigid support 793 is any electrically insulating rigid body capable of supporting the switchgear 710 and securing it to the utility structure.

[0093] The first end 794 is connected to the mechanical interface 789 via a temporary but robust attachment mechanism 796, which is strong enough to secure the rigid support 793 to the mechanical interface 789. Furthermore, the attachment mechanism 796 allows the rigid support 793 to be removed from the mechanical interface 789 without damaging the mechanical interface 789, the housing 780, or the rigid support 793. The attachment mechanism 796 can be, for example, a screw and corresponding hole, a block or post and corresponding opening, or any other mechanical fastener. The attachment mechanism 796 allows the rigid support 793 to be repeatedly attached to and removed from the housing 780, for example, along path L.

[0094] This configuration allows the switchgear 710 to be easily converted into switchgear that can be mounted on insulating mounting brackets (with mounting assemblies 150 and 170, 250 (or 350)) and 270, 450 and 470, or 550 and 570) and switchgear that can be mounted on utility structures. Therefore, the usability of the switchgear 710 is enhanced, and end users achieve cost and time savings.

[0095] Mechanical interfaces 689 and 789 are examples of interfaces, and other types of interfaces can be used. (See also: [link to reference]). Figure 8 For example, the interface could be a connecting strap 899 that surrounds the box. Other implementations are also possible. For example, the interface could be a bracket that partially surrounds the box or is mounted to three or two sides of the box. As another example, Figure 2The illustrated embodiment includes mounting components 250 and 270 that securely fasten device 210 to circuit breaker 240, preventing device 210 from moving relative to circuit breaker 240. However, other embodiments are possible. For example, second mounting component 270 can be replaced with second mounting component 470 or second mounting component 570, allowing the second end 228 of the body to move relative to the circuit breaker or other support structure. Such configurations are easier to install into circuit breakers and can be used as retrofit kits to accommodate rod-mount designs, thus adapting to circuit breakers.

[0096] In embodiments where body 120 or 220 is intended for connection only to an insulating mounting bracket that allows the body to detach, body 120 or 220 may be implemented without an insulating baffle. The insulating mounting bracket that allows the body or switching device to detach may be referred to as a visible disconnect mounting bracket.

[0097] Any of the above-described switching devices can be configured for installation on utility structures or insulated mounting brackets. (See reference) Figure 9 This insulating mounting bracket can be used as a conventional circuit breaker mounting component. Figure 9 A switching device 610 is shown mounted to a conventional circuit breaker mount 940. The circuit breaker mount 940 is substantially C-shaped and includes a lower portion 941 and an upper portion 942. A connecting portion 943 extends between the lower portion 941 and the upper portion 942. An insulating baffle 945 extends radially outward from the connecting portion 943.

[0098] The second electrical terminal 624 is connected to the upper portion 942 of the circuit breaker mount 940 via mounting assembly 970 and to the lower portion 941 via mounting assembly 950. Mounting assembly 970 is any type of mechanism that allows the second electrical terminal 624 to be released from the upper portion 942, such that the switching device 610 is detached from the circuit breaker mount 940. Mounting assembly 950 is any type of mechanism including a pivot 951 that allows the switching device to swing about an arc in the YZ plane. Mounting assembly 950 and / or mounting assembly 970 may have various aspects of the mounting assemblies described above, or may be components known in the art.

[0099] Figures 10A to 10E Various views of the switchgear 1010 are shown. The switchgear 1010 can be installed in a high-power power distribution system 100. Figure 1 More than one type of structure in ) . For example, switch device 1010 can be installed on a utility pole (such as Figure 10A and Figure 10B (as shown) or mounted to the crossarm (such as Figures 10C to 10E (As shown). Figure 10A A front external view of the switchgear 1010 installed on the utility pole 1095. Figure 10B External side view of the switchgear 1010 installed on the utility pole 1095. Figure 10C A front external view of the switch device 1010 installed on the cross arm 1097. Figure 10D Rear perspective view of the switchgear 1010 mounted on the cross arm 1097. Figure 10E External side view of the switchgear 1010 mounted on the cross arm 1097.

[0100] refer to Figure 10A and Figure 10B The switchgear 1010 includes a housing 1080. The housing 1080 is either energized or ungrounded. The switchgear 1010 is a single-phase recloser, which includes an interruption mechanism, such as a vacuum interrupter, switching device, or fault interrupter; a current transformer; and an embedded controller. The recloser also includes supporting accessories and associated devices, such as a power supply, and may also include other components and devices, such as a communication interface and measuring devices other than the current transformer. The embedded controller can communicate with remote stations (such as...) Figure 1 The remote station (199) communicates. The interrupt mechanism may include, for example, actuators, mechanisms, operating levers, and current exchange, and may also include additional associated devices and components. The various components of the interrupt mechanism are not listed in... Figures 10A to 10D As shown.

[0101] The switching device 1010 also includes bodies 1020a, 1020b, and 1020c. An interrupting mechanism may be located in body 1020a or body 1020c. In other words, in some embodiments, the interrupting mechanism is located in body 1020c, and in some embodiments, the interrupting mechanism is located in body 1020a. An embedded controller and a current transformer may be located in housing 1080. The current transformer may be encapsulated in body 1020a or body 1020c, depending on the location of the interrupting mechanism. The current transformer may be paired with the interrupting mechanism in body 1020a or body 1020c, or may be placed around conductors in either body 1020a or body 1020c that does not contain an interrupting mechanism. The embedded controller may be located in housing 1080. Body 1020b may contain actuators and mechanisms. Some or all of the actuators and mechanisms may be located in body 1020b or housing 1080.

[0102] Other implementations are also possible. For example, the interruption mechanism may be located in body 1020b, and some actuators and mechanisms may be located in body 1020a or 1020c. Furthermore, in embodiments where the interruption mechanism and current transformer are located in body 1020a or body 1020c, body 1020b may also be used for voltage sensing or power harvesting. For example, one or more high-impedance resistors may be embedded in body 1020b to facilitate voltage sensing and / or power harvesting.

[0103] The switching device 1010 also includes a freeze protection cover 1091 mounted on the outside of the housing 1080. The freeze protection cover includes a manual operating handle and a second handle (not shown) for the hot wire tag.

[0104] Each body 1020a, 1020b, 1020c is a three-dimensional body made of an electrically insulating material. For example, bodies 1020a, 1020b, 1020c may be made of ceramic or polymer. Body 1020b extends along the Z-direction from housing 1080 to mounting position 1084b, which extends from body 1020b. Mounting position 1084b is connected to mounting bracket 1086A. Mounting bracket 1086A is an L-shaped mounting bracket, which is mounted to pole 1095 using fastening device 1086B (e.g., bolts, nails, or screws). When mounting bracket 1086A is connected to pole 1095, switchgear 1010 is mounted to pole 1095. Body 1020a extends along the Y-direction from housing 1080 to source / load connection point 1087a, and body 1020c extends along the -Y-direction from housing 1080 to source / load connection point 1087c. Each of the main bodies 1020a, 1020b, and 1020c includes a radially outwardly extending baffle 1045.

[0105] The switchgear 1010 also includes an on / off indicator 1082. The on / off indicator 1082 is coupled to the interrupting mechanism / mechanism / actuator assembly and provides a visible indication of whether the interrupting mechanism is open (the contacts of the interrupting mechanism are separate) or closed (the contacts of the interrupting mechanism are in physical contact). When the switchgear 1010 is mounted on the pole 1095, the on / off indicator 1082 is located on the underside or bottom side of the housing 1080. This orientation enhances the visibility of the on / off indicator 1082 for an operator viewing the switchgear 1010 from below.

[0106] refer to Figure 10C , Figure 10D and Figure 10E The switchgear 1010 is shown mounted to a crossarm 1097. The crossarm 1097 is mounted to another structure in the power distribution system 100, such as a utility pole. In 10C, Figure 10D and Figure 10E In the example shown, the cross arm 1097 is along the X direction (in and out). Figure 10C The crossarm 1097 extends from the page in the diagram and is attached to the utility pole 1095 extending along the Z direction. The crossarm 1097 is a solid rod-shaped structure with a rectangular or square cross-section.

[0107] Mounting bracket 1086C is used to mount the switching device 1010 to the cross arm. Mounting bracket 1086C is attached to mounting position 1084b. When attached to mounting position 1084b, mounting bracket 1086C extends in the Z direction. Mounting bracket 1086C includes a base portion 1067a, a middle portion 1067b, and a top portion 1067c. Base portion 1067a is connected to mounting position 1084b. Base portion 1067a may have an opening, for example, to receive mounting position 1084b, such that mounting position 1084b is secured to base portion 1067a by, for example, a nut. Middle portion 1067b is connected to base portion 1067a. In the example shown, middle portion 1067b is multiple rods or multiple bolts. Top portion 1067c is a substantially flat piece extending in the XY plane and connected to middle portion 1067b. Top portion 1067c is connected to middle portion 1067b. When joined together, a portion of the base portion, the middle portion 1067b, and the top portion 1067c surround the cross arm 1097, such that the switching device 1010 is mounted to the cross arm 1097. Other embodiments are also possible. For example, the middle portion 1067b and the top portion 1067c may be configured to connect to the base portion 1067a and to a single piece that surrounds and secures the cross arm 1097.

[0108] refer to Figure 10D The figure is a rear perspective view of the switching device 1010. The housing 1080 also includes a baffle 1045D located on the side of the housing 1080 opposite to the antifreeze cover 1091. For example, the baffle 1045D can be used to provide a visible indication that the housing 1080 is energized.

[0109] In summary, the switchgear 1010 can be mounted to the utility pole 1095 or the crossarm 1097. Mounting bracket 1086A is connected to mounting position 1084b to mount the switchgear 1010 to the utility pole 1095. Mounting bracket 1086C is connected to mounting position 1084b to mount the switchgear 1010 to the crossarm 1097.

[0110] All other features are within the scope of the claims. For example, L-shaped mounting bracket 1086A and clamp mounting bracket 1086C are provided as examples of mounting assemblies that can be used to mount the switch device 1010 into a high-power power distribution system. Other forms of mounting assemblies may be used.
