[0043] Figure 1 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 can include, for example, one or more distribution lines, cables, and / or any other mechanism for transmitting power. The power distribution system 100 can be, for example, an electrical grid, an electrical system, or a multi-phase electrical network that provides power to commercial and / or residential customers. The power distribution system 100 can have an operating voltage of, for example, at least 1 kilovolt (kV), up to 34.5 kV, up to 38 kV, up to 69 kV, or 69 kV or more. The power distribution system 100 is an alternating current (AC) electrical network and can operate, for example, at a fundamental frequency of 50 to 60 hertz (Hz).

[0044] The power distribution system 100 includes a switchgear 110. The device 110 includes a main body 120 that encloses a switch 112. The switch 112 is any type of device capable of interrupting power to the electrical load 102. The switch 112 can have a voltage rating of, for example, between 15 kV and 38 kV, between 15 kV and 30 kV, a voltage greater than 15 kV, 15 kV, or 29.2 kV. The switch 112 can have a continuous current rating of, for example, between 100 amperes (A) and 600 A, or between 100 and 200 A. The switch 112 is capable of interrupting a fault current of, for example, 1 kA to 10 kA, 1 kA to 4 kA, 1 kA to 7 kA, or 6.3 kA. The switch 112 can be, for example, a switch capable of being repeatedly opened and closed, 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 being repeatedly opened and closed, such as a fuse, can be used as the switch 112. In embodiments where the switch 112 is a vacuum interrupter or other switch capable of being repeatedly opened and closed, the device 110 is a recloser and can be a single-phase solid dielectric recloser.

[0045] The switch 112 includes associated components 113. In embodiments where the switch 112 is a vacuum interrupter and the device 110 is a recloser, the associated components 113 can include actuating devices to cause opening and closing of contacts of the vacuum interrupter 112, and electronics for controlling these actuating devices and for communicating with a remote station 199. The remote station 199 can be, for example, a remote control or a remote laptop or other computing device.

[0046] The body 120 is physically connected or mounted to the mounting structure 140. Specifically, the body 120 is mechanically connected to the lower portion 141 of the mounting structure 140 by the first mounting assembly 150, and the body 120 is mechanically connected to the upper portion 142 of the mounting structure 140 by the second mounting assembly 170. The first and second mounting assemblies 150, 170 provide a variety of mounting options and increase the usability of the device 110. For example, the first and second mounting assemblies 150, 170 allow the body 120 to be mounted to a variety of different types of mounting structures, such as an insulated mounting bracket that can be a fuse cutout, a cutout without a fuse, or a visible disconnect mounting bracket. This allows standardization of the end user's inventory and installation procedures, and improves the ease of use and efficiency of the device 110.

[0047] The switch 112 is electrically connected to the first and second terminals 122, 124 via electrical connections 129. In embodiments where the switch 112 is a vacuum interrupter, the electrical connections 129 include actuators and operating rods that open and close the electrical contacts of the switch 112. The first and second terminals 122, 124 are made of an electrically conductive material, such as copper, a copper alloy, or any other metallic material. The body 120 is a three-dimensional object that extends from the first end 126 to the second end 128. In Figure 1 In the illustrated example, the second terminal 124 extends from the second end 128 of the body 120, and the first terminal 122 extends from the first end 126 of the body 120. The second terminal 124 can extend through a second opening in the body 120, and the first terminal 122 can extend through a first opening in the body 120. The body 120 is made of an electrically insulating material, such as a ceramic, a robust polymer, or any other suitable electrically insulating material. The body can or can not include an insulating baffle.

[0048] In the illustrated example, the second terminal 124 is electrically connected to the power source 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 source 101.

[0049] The electrical load 102 is any device or equipment that utilizes electrical power, and can include electrical equipment that receives and transmits or distributes electrical power to other equipment in the electrical distribution system 100. The electrical load 102 can include, for example, transformers, switching equipment, energy storage systems, computers and communications equipment; lighting, heating and air conditioning; motors and electrical machinery in manufacturing facilities; and / or appliances and systems in residential buildings. The power source 101 is any source of electrical power, such as a power plant that generates electrical power from fossil fuels or from thermal energy or substation. The power source 101 can include one or more distributed energy sources, such as a solar power system that includes an array of photovoltaic (PV) devices that convert sunlight into electrical power or a wind-based energy system. More than one power source can supply power to the electrical distribution system 100, and more than one type of power source can supply power to the electrical distribution system 100.

[0050] Under normal and expected operating conditions, the switch 112 is closed. Current flows through the switch 112 and is delivered to the electrical load 102. In the presence of a fault condition (e.g., current and / or voltage that exceeds safe operating parameters of the electrical load 102), the switch 112 opens to interrupt power to the electrical load 102. In embodiments where the switch 112 is a recloser, the switch 112 can close and reopen multiple times before locking and remaining open to attempt to clear the fault.

[0051] Reference Figure 2 , Figure 3 , Figures 4A to 4G and Figures 5A to 5F Various embodiments of the first mounting assembly 150 and the second mounting assembly 170 will be discussed below. Figures 6 to 8 Various embodiments of a switching device having a dual mounting or universal mounting system are shown in FIGS.

[0052] Figure 2 is a side view block diagram of a device 210. The device 210 is an embodiment of the device 110 Figure 1 The device 210 includes a body 220 that encloses the switch 112. The switch 112 is electrically connected to a source terminal 224 that extends from a second end 228 of the body 220, and is electrically connected to a load terminal 222 proximate a first end 226 of the body 220. The source terminal 224 is configured to be electrically connected to a source (such as the power source 101 of FIG. 1) that provides electrical power to the device 210. The load terminal 222 is configured to be electrically connected to a load (such as the electrical load 102 of FIG. 1) that receives electrical power from the device 210. Figure 1 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.

[0053] 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.

[0054] 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 of a single continuous insulating material piece, 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.

[0055] 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.

[0056] 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 2In the example shown, the load terminal 222 is a ring assembly having a circular cross-section in the X-Y plane. The ring assembly includes threaded openings or holes 223, any of which can receive the threaded terminal connection end 254 of the first connection portion 251.

[0057] The load terminal 222 can include six openings 223, each spaced apart from one another by a spacing of, for example, about 60 degrees. Other configurations of the ring assembly are possible. For example, the ring assembly can include more or less than six openings 223. The openings 223 can be spaced apart in any configuration suitable for the present application. For example, the openings 223 can be non-uniformly spaced apart.

[0058] The first connection plate 252 is attached to the second end 255 of the first connection portion 251. The first connection plate 252 is perpendicular to the first connection portion 251, and the first connection portion 251 is attached to the first connection plate 252 at or near the center of the first connection plate 252. In the example shown, the first connection plate 252 is a circular plate having a diameter of about 1.5 inches. Figure 2 In the example shown, the body 220 extends in the Z direction, and when the first connection portion 251 is connected to the load terminal 222, the first connection portion 251 extends in the Y direction, and the first connection plate 252 extends in the Z direction. The first connection plate 252 and the first connection portion 251 can be two pieces that are permanently attached to one another by, for example, welding, brazing, or soldering. In some embodiments, the first connection plate 252 and the first connection portion 251 are formed from a single piece.

[0059] The second connection plate 253 is a plate-like structure attached to the second connection portion 256. The first and second connection plates have respective surfaces 265 and 266 that are substantially flat and extend in the X-Z plane. An end 257 of the second connection portion 256 is attached to an end region 258 of the second connection plate 253. The second connection portion 256 extends from the end region 258 at an angle 259. The angle 259 is less than 90 degrees (°). The second connection plate 253 and the second connection portion 256 can be formed from separate pieces that are permanently joined, or the second connection plate 253 and the second connection portion 256 can be formed from a single piece of material.

[0060] To join the load terminal 222 to the lower portion 241 of the circuit breaker 240, the threaded terminal connection end 254 of the first connection portion 251 is threaded into one of the openings 223 in the load terminal 222. The first and second connection plates 252 and 253 are positioned with their respective surfaces 265 and 266 facing one another. The plates 252 and 253 are mounted to one another by fasteners 264, such as screws.

[0061] The second connecting portion 256 extends away from the surface 266. The second connecting portion 256 includes an opening 260 (shown in dashed lines), and the lower portion 241 includes an opening 246 (shown in dashed lines). The opening 260 aligns with the opening 246 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. A fastener 262 passes through the opening 246 and the opening 260 to connect the second connecting portion 256 to the lower portion 241. The fastener 262 can include a screw that passes through the opening 246 and the opening 260, and is secured by a nut.

[0062] Referring also to FIG. 3, Figure 3 a first mounting assembly 350 is shown. The first mounting assembly 350 is another embodiment of the first mounting assembly 250. The first mounting assembly 350 can be used with the main 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 portions than the first mounting assembly 250. Thus, the first mounting assembly 350 can be easier to manufacture than the first mounting assembly 250.

[0063] The first connecting portion 351 includes a threaded end portion 354 (shown in shading) that is configured to connect to one of the threaded openings 223 in the load terminal 222. The second connecting portion 352 connects to an end 355 of the first connecting portion 351. The end 355 is opposite the end portion 354. The second connecting portion 352 extends perpendicularly to the first connecting portion 351 to an end 358. The third connecting portion 353 meets the second connecting portion 352 at the end 358. The third connecting portion 353 extends at an angle 359 relative to the second connecting portion 352. The angle 359 is less than 90°. When the threaded end portion 354 is connected to one of the threaded openings 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 the fastener 262 through the opening 360 and the opening 246 and securing the fastener 262.

[0064] Referring again to FIG. 3, Figure 2 Regardless of which embodiment 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 main body 220. Neither the first mounting assembly 250 nor the first mounting assembly 350 allows the main body 220 to rotate or otherwise move relative to the circuit breaker 240 in the Y-Z plane.

[0065] The second mounting assembly 270 includes a one-piece connecting portion 271. The connecting portion 271 includes a first region 272 and a second region 273 that is angled relative to the first region 272. The first region 272 and the second region 273 are substantially planar pieces. The angle between the first region 272 and the second region 273 is greater than 90°. The first region 272 includes an opening 276 that receives the source terminal 224. The second region 273 includes an opening 275, and the upper portion 242 includes an opening 247. When the connecting 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 is aligned with the opening 275. A fastener 249 passes through the opening 275 and the opening 275 to secure the connecting 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.

[0066] After the body 220 is attached to the circuit breaker 240 with the first mounting assembly 250 (or 350) and the second mounting assembly 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 assembly 250 (or 350) and the second mounting assembly 270 hold the body 220 in a fixed position in the circuit breaker 240 so that the body 220 does not move relative to the circuit breaker.

[0067] Figure 4A And Figure 4B is a side view of the device 410. The device 410 is another embodiment of the device 110 Figure 1 ) of FIG. 1. Figure 4A The device 410 is shown in a locked state. Figure 4B The device 410 is shown in a released state.

[0068] The device 410 includes the body 220, the load terminal 222, the source terminal 224, and the circuit breaker 240. The source terminal 224 is connected to a post structure 425. The post structure 425 extends into and out of the page. Figure 4A And Figure 4B The device 410 includes a first mounting assembly 450 and a second mounting assembly 470. The mounting assemblies 450 and 470 mount the body 220 to the circuit breaker 240.

[0069] The 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 can be made of a relatively thin piece of metal. Figures 4C to 4EVarious aspects of the mounting assembly 450 are shown. Figure 4C is a side view of the connecting portion 451. Figure 4D is a view of the connecting portion 451 in the X-Y plane. Figure 4E is a perspective view of the release lever 453.

[0070] The 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 a pivot point 483. The arm 457 is rotatable about the pivot point 483 in the Y-Z plane. The release lever 453 also includes a lever 456 at the second end 459. The lever 456 extends perpendicular to the arm 457.

[0071] The connecting portion 451 is a rigid piece that connects to the lower portion 241 of the circuit breaker 240. The connecting portion 451 includes an opening 460. The fastener 262 passes through the opening 460 and an opening 246 (located on the circuit breaker 240) to secure the connecting portion 451 to the lower portion 241 of the circuit breaker 240.

[0072] The spring-loaded cam keeper 452 is attached to the connecting portion 451 by a fastener 464. The spring-loaded cam keeper 452 includes a hook portion 454. Reference is also made to Figure 4D The connecting portion 451 and the hook portion 454 are substantially U-shaped in the X-Y plane such that there is an open central region 462 in the connecting portion 451.

[0073] Reference is also made to Figure 4F and Figure 4G The second mounting assembly 470 includes a pivot body 471. Figure 4F A cross-sectional view of the pivot body 471 in the Y-Z plane is shown. Figure 4G A side view of the pivot body 471 in the X-Y plane is shown. In Figure 4G the hidden lines are shown in a dashed line style. The pivot body 471 includes a first portion 475, a second portion 476, and a recess 477 between the first portion 475 and the second portion 476.

[0074] A hole 474 extends from a 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.

[0075] The slot 479 Figure 4G) provides an opening through the first portion 475 to the recess 477. The slot 479 and the recess 477 are sized to receive and secure the source terminal 224 and the stem structure 425, respectively. The source terminal 224 and the stem structure 425 are moved along the arrow 485( Figure 4F ) and into the recess 477 and the slot 479. Figure 4G The source terminal 224 in the slot 479 and the stem structure 425 in the recess 477 are shown.

[0076] Referring again to Figure 4A When the body 220 is attached to the interrupter 240, the stem 456 of the release lever 453 engages the outside of the hook portion 454, and the arm 457 is in the open area 462( Figure 4D ). To release the body 220 from the interrupter 240, the release lever 453 is rotated about the pivot point 483 until the stem 456 clears the hook portion 454. Referring again to Figure 4F and Figure 4G When the first end 226 of the body 220 is not connected to the interrupter 240, the stem structure 425 is rotated in the recess 477 (of the second mounting assembly 270) and the load terminal 222 and the body 220 are rotated or pivoted in the Y-Z plane so that the first end 226 of the body 220 is away from the interrupter 240. Figure 4B This condition is shown. By pressing the body 220 at the push point 488, the body 220 can be pressed back into the interrupter 240 so that the release lever 453 again engages the hook portion 454. The push point 488 can be configured to engage with a live operating lever so that an operator can push the body 220 into the interrupter 240 from a safe and / or convenient position.

[0077] Thus, the mounting assemblies 450 and 470 allow the first end 226 of the body 220 to swing away from the lower portion 241 of the interrupter 240 while the source terminal 224 remains attached to the upper portion 242 of the interrupter 240. The mounting assemblies 450 and 470 can improve the overall efficiency and ease of use of the device 410. For example, the body 220 can be more easily installed into the interrupter 240 with a live operating lever because the live operating lever is pushed below the center of gravity of the body 220. In addition, the mounting assemblies 450 and 470 can be used as part of a retrofit to adapt a device that was originally intended to be stem-mounted into a device that can be mounted to an interrupter.

[0078] Figure 5A A side view of the device 510 in the locked condition. Figure 5Bis in a released state. Device 510 is another embodiment of device 410. Device 510 includes body 220, terminals 222 and 224, and stem structure 425. Device 510 also includes first mounting assembly 550 and second mounting assembly 570, and connecting portion 551 connected to one of the openings 223 on load terminal 222. First mounting assembly 550 and second mounting assembly 570 connect body 220 to insulated mounting structure 540. When first mounting assembly 550 is locked ( Figure 5A ), end 555 of connecting portion 551 is secured in loop region 557 by release mechanism 553. When first mounting assembly 550 is released (as shown in Figure 5B ), stem structure 425 and body 220 are rotated in the Y-Z plane, and first end 226 of body 220 swings away from insulated mounting structure 540.

[0079] Figure 5C and Figure 5D are front and side views, respectively, of second mounting assembly 570. Figure 5E shows first mounting assembly 550 in a locked position. Figure 5F shows first mounting assembly 550 in a released position. Second mounting assembly 570 includes connecting portion 571 extending from first end 572 to curved end 573. First end 572 is attached to upper portion 542 of insulated mounting structure 540. First end 572 can be attached to upper portion 542 with, for example, bolts or other fasteners. Connecting portion 571 extends from first end 572 and curves or tilts slightly downward (in the -Z direction) and then curves upward (in the Z direction) to curved end 573. Connecting portion 571 is a track with an open central region 574. Terminal 424 fits in open region 574, and curved end 573 holds stem structure 425. When first mounting assembly 550 is released, stem structure 425 is held by curved end 573, and stem structure 425 and body 220 are rotated in the Y-Z plane.

[0080] Referring to Figure 5E , first mounting assembly 550 includes loop region 557, friction track 552, and release mechanism 553. Loop region 557 forms a semicircular opening at lower portion 541 of insulated mounting structure 540. In the locked position ( Figure 5A and Figure 5E ), release mechanism 553 holds end 555 of connecting portion 551 in loop region 557. Release mechanism 553 holds end 555 in the locked state ( Figure 5A and Figure 5E ), and releases end 555 in the released state ( Figure 5B and Figure 5F). The release mechanism 553 can be, for example, a latch or a hinged retainer that, in the locked state, engages the tip 555 such that the tip 555 is held in the loop region 557. The release mechanism 553, in the released state, moves out of the way of the tip 555 to allow the tip 555 to move along the friction track 552 and out of the loop region 557.

[0081] After the release mechanism 553 becomes the released state, as the lever structure 425 and the body 220 rotate in the Y-Z plane, the tip 555 moves along the friction track 552. The friction track 552 inhibits or prevents movement of the tip 555 (and thus also 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 inadvertently swinging back to the locked position. Thus, the friction track 552 also protects the switch 112 and the components 113 from electrical shock and damage. Furthermore, in the event of a power outage, the friction track 552 allows the body 220 to swing back to the locked position, which can be advantageous for safety reasons. Figure 5A and Figure 5B In the embodiment shown in FIGS. 15-17, the device 510 can fall onto the connecting portion 571 and will land on the friction track 552. Thus, Figure 5A and Figure 5B The configuration shown in FIGS. 15-17 improves the efficiency of installation and replacement of the device 510.

[0082] Any of the mounting assemblies 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 described above can be used to connect a switch device, such as a single-phase recloser to an insulated mounting bracket. Furthermore, any of the mounting assemblies 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 described above can be used with a switch device that is configured to be connected to a utility structure or an insulated mounting bracket. A utility structure is a large structure in an electrical power distribution system that is typically intended to be permanent. Examples of utility structures include wooden utility poles, any other type of large pole, or a concrete structure.

[0083] Referring to FIGS. 18-20, any of the mounting assemblies 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 described above can be used with a switch device 610 or 620 as shown in Figure 6 and Figure 7 FIGS. 18-20. Any of the mounting assemblies 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 described above can be used with a switch device 610 or 620 as shown in Figure 6 FIGS. 18-20. Any of the mounting assemblies 150 and 170, 250 (or 350) and 270, 450 and 470, or 550 and 570 described above can be used with a switch device 610 or 620 as shown in Figure 7The 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] The first end 694 is connected to the mechanical interface 689 by a temporary but secure attachment mechanism 696. The mechanism 696 is secure enough to fix the rigid support 693 to the mechanical interface 689. In addition, the attachment mechanism 696 also allows the rigid support 693 to be removed from the mechanical interface 689 without damaging the mechanical interface 689, the box 680, or the rigid support 693. The attachment mechanism 696 can be, for example, a screw and a corresponding hole, a block or a post and a corresponding opening, or any other mechanical fastener. The attachment mechanism 696 allows the rigid support 693 to be repeatedly attached to the box 680 and removed from the box, for example, along the path L.

[0089] This configuration allows the switch device 610 to be easily converted from a switch device that can be installed to an insulated mounting bracket (with the mounting assemblies 150 and 170, 250 (or 350)) and 270, 450 and 470, or 550 and 570) and a switch device that can be installed to a utility structure. Thus, the availability of the switch device 610 is enhanced, and the end user realizes cost and time savings.

[0090] Figure 7 is a side view of the switch device 710. The switch 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 electrically insulating material. An insulating baffle 721 extends outwardly from an exterior surface of the housing 720. The first end 726 is attached to the load terminal 222, and a terminal 724 extends through the second end 728. The housing encloses a switch (not shown but similar to the switch 112). The switch is electrically connected to the terminal 724 and the terminal 722. Figure 7 is a side view of the switch device 710. The switch 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 electrically insulating material. An insulating baffle 721 extends outwardly from an exterior surface of the housing 720. The first end 726 is attached to the load terminal 222, and a terminal 724 extends through the second end 728. The housing encloses a switch (not shown but similar to the switch 112). The switch is electrically connected to the terminal 724 and the terminal 722.

[0091] The switch device 710 includes a box 780 coupled to the load terminal 222. The box 780 is not grounded. The box 780 includes a mechanical interface 789 configured to attach the box 780 to a utility structure. The mechanical interface 789 is connected to a rigid support 793. The rigid support 793 extends from a first end 794 to a second end 795. Because the box 780 is not grounded, the rigid support 793 is made of electrically insulating material and can include an insulating baffle. The rigid support 793 is any electrically insulating rigid body capable of supporting the switch device 710 and fixing the switch device to a utility structure.

[0092] The first end 794 is connected to the mechanical interface 789 by a temporary but secure attachment mechanism 796 that is strong enough to secure the rigid support 793 to the mechanical interface 789. In addition, the attachment mechanism 796 also allows the rigid support 793 to be removed from the mechanical interface 789 without damaging the mechanical interface 789, the box 780, or the rigid support 793. The attachment mechanism 796 can be, for example, a screw and a corresponding hole, a block or a post and a corresponding opening, or any other mechanical fastener. The attachment mechanism 796 allows the rigid support 793 to be repeatedly attached to the box 780 and removed from the box, for example, along the path L.

[0093] This configuration allows the switchgear 710 to be easily converted from a switchgear that can be installed to an insulated mounting bracket (with mounting assemblies 150 and 170, 250 (or 350)) and 270, 450 and 470, or 550 and 570) and a switchgear that can be installed to a utility structure. Thus, the availability of the switchgear 710 is enhanced, and the end user realizes cost and time savings.

[0094] The mechanical interfaces 689 and 789 are examples of interfaces, and other types of interfaces can be used. See, for example, Figure 8 For example, the interface can be a connecting band 899 that wraps around the box. Other implementations are possible. For example, the interface can be a bracket that partially encloses the box or is mounted to three sides or two sides of the box. As another example, Figure 2 The implementation shown includes mounting assemblies 250 and 270 that secure the device 210 to the disconnector 240 in a fixed manner so that the device 210 does not move relative to the disconnector 240. However, other implementations are possible. For example, the second mounting assembly 270 can be replaced with a second mounting assembly 470 or a second mounting assembly 570 so that the second end 228 of the body can move relative to the disconnector or other support structure. Such a configuration can be easier to install into a disconnector and can be used as a retrofit kit to adapt a pole-mounted design to fit into a disconnector.

[0095] In implementations where the body 120 or 220 is intended for connection to an insulated mounting bracket that allows the body to fall off, the body 120 or 220 can be implemented without an insulating baffle. An insulated mounting bracket that allows a body or switchgear to fall off can be referred to as a visible disconnect mounting bracket.

[0096] Any of the switchgears described above can be configured to be installed to a utility structure or an insulated mounting bracket. See, for example, Figure 9 The insulated mounting bracket can be a conventional disconnector mounting. Figure 9A switch device 610 is shown mounted to a conventional circuit breaker mounting 940. The circuit breaker mounting 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.

[0097] A second electrical terminal 624 is connected to the upper portion 942 of the circuit breaker mounting 940 by a mounting assembly 970 and to the lower portion 941 by a mounting assembly 950. The mounting assembly 970 is any type of mechanism that allows the second electrical terminal 624 to be released from the upper portion 942 so that the switch device 610 is detached from the circuit breaker mounting 940. The mounting assembly 950 is any type of mechanism that includes a pivot 951 that enables the switch device to swing about an arc in the Y-Z plane. The mounting assembly 950 and / or the mounting assembly 970 can have aspects of the mounting assemblies described above, or can be assemblies known in the art.

[0098] Figures 10A to 10E Various views of a switch device 1010 are shown. The switch device 1010 can be mounted to more than one type of structure in a high power electrical power distribution system 100 Figure 1 ). For example, the switch device 1010 can be mounted to a utility pole (such as shown in Figure 10A and Figure 10B ) or to a crossarm (such as shown in Figures 10C to 10E ). Figure 10A is a front exterior view of the switch device 1010 mounted to a utility pole 1095. Figure 10B is a side exterior view of the switch device 1010 mounted to a utility pole 1095. Figure 10C is a front exterior view of the switch device 1010 mounted to a crossarm 1097. Figure 10D is a rear perspective view of the switch device 1010 mounted to a crossarm 1097. Figure 10E is a side exterior view of the switch device 1010 mounted to a crossarm 1097.

[0099] Referring to Figure 10A and Figure 10B , the switch device 1010 includes a tank 1080. The tank 1080 is a live or ungrounded tank. The switch device 1010 is a single-phase recloser that includes an interrupting mechanism, such as a vacuum interrupter, a switch device, or a fault interrupter; a current transformer; and an embedded controller. The recloser also includes support accessories and associated equipment, such as a power supply, and can also include other components and equipment, such as a communications interface and a measurement device other than a current transformer. The embedded controller can be in communication with a remote station, such as a Figure 1the remote station 199) communication. The interrupt mechanism can include, for example, actuators, mechanisms, levers, and current switches, and can also include additional associated devices and components. The various components of the interrupt mechanism are not shown in Figures 10A to 10D shown.

[0100] The switch device 1010 also includes bodies 1020a, 1020b, and 1020c. The interrupt mechanism can be located in the body 1020a or the body 1020c. In other words, in some embodiments, the interrupt mechanism is located in the body 1020c, and in some embodiments, the interrupt mechanism is located in the body 1020a. The embedded controller and the current transformer can be located in the box 1080. The current transformer can be enclosed in the body 1020a or the body 1020c, depending on where the interrupt mechanism is located. The current transformer can be paired with the interrupt mechanism in either the body 1020a or the body 1020c, or can be placed around the conductors in either of the bodies 1020a or 1020c that does not contain the interrupt mechanism. The embedded controller can be located in the box 1080. The body 1020b can contain actuators and mechanisms. Some or all of the actuators and mechanisms can be located in the body 1020b or the box 1080.

[0101] Other embodiments are also possible. For example, the interrupt mechanism can be located in the body 1020b, and some of the actuators and mechanisms can be located in the body 1020a or 1020c. In addition, in embodiments where the interrupt mechanism and the current transformer are located in the body 1020a or the body 1020c, the body 1020b can also be used for voltage sensing or power harvesting. For example, one or more high impedance resistors can be embedded in the body 1020b to facilitate voltage sensing and / or power harvesting.

[0102] The switch device 1010 also includes a freeze shield 1091 mounted on the outside of the box 1080. The freeze shield includes a manually operated handle and a second handle (not shown) for a hot line tag.

[0103] Each of the bodies 1020a, 1020b, 1020c is a three-dimensional body made of an electrically insulating material. For example, the bodies 1020a, 1020b, 1020c can be made of a ceramic or a polymer. The body 1020b extends from the box 1080 in the Z-direction to a mounting location 1084b that extends from the body 1020b. The mounting location 1084b is connected to a mounting bracket 1086A. The mounting bracket 1086A is an L-shaped mounting bracket that is mounted to a utility pole 1095 with a fastening device 1086B (e.g., a bolt, a peg, or a screw). When the mounting bracket 1086A is connected to the utility pole 1095, the switch device 1010 is mounted to the utility pole 1095. The body 1020a extends from the box 1080 in the Y-direction to a source / load connection point 1087a, and the body 1020c extends from the box 1080 in the -Y-direction to a source / load connection point 1087c. Each of the bodies 1020a, 1020b, 1020c includes a radially outwardly extending baffle 1045.

[0104] The switch device 1010 also includes an open / closed indicator 1082. The open / closed indicator 1082 is coupled to the interrupting mechanism / assembly / 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 switch device 1010 is mounted on the utility pole 1095, the open / closed indicator 1082 is on the underside or bottom side of the box 1080. This orientation enhances the visibility of the open / closed indicator 1082 for an operator observing the switch device 1010 from below.

[0105] Referring to Figure 10C , Figure 10D and Figure 10E , the switch device 1010 is shown mounted to a cross arm 1097. The cross arm 1097 is mounted to another structure in the power distribution system 100, such as a utility pole. In the example shown in 10C, Figure 10D and Figure 10E , the cross arm 1097 extends along the X-direction (into and out of the page in Figure 10C , and is attached to a utility pole 1095 that extends along the Z-direction. The cross arm 1097 is a solid, rod-like structure with a rectangular or square cross-section.

[0106] A mounting bracket 1086C is used to mount the switchgear 1010 to the crossarm. The mounting bracket 1086C is attached to the mounting location 1084b. When attached to the mounting location 1084b, the mounting bracket 1086C extends in the Z direction. The mounting bracket 1086C includes a base portion 1067a, an intermediate portion 1067b, and a top portion 1067c. The base portion 1067a is connected to the mounting location 1084b. The base portion 1067a can have, for example, an opening that accepts the mounting location 1084b, such that the mounting location 1084b is secured to the base portion 1067a with, for example, a nut. The intermediate portion 1067b is connected to the base portion 1067a. In the example shown, the intermediate portion 1067b is a plurality of rods or bolts. The top portion 1067c is a substantially flat piece that extends in the X-Y plane and is connected to the intermediate portion 1067b. The top portion 1067c is connected to the intermediate portion 1067b. When engaged together, the base portion, the intermediate portion 1067b, and the top portion 1067c enclose the crossarm 1097, such that the switchgear 1010 is mounted to the crossarm 1097. Other embodiments are possible. For example, the intermediate portion 1067b and the top portion 1067c can be a single piece that is configured to connect to the base portion 1067a and to enclose and secure the crossarm 1097.
