[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0030] The cable assembly provided in the present application can be applied to power systems such as solar energy, etc. It can be applied to, but not limited to, the secondary side connection of current transformers in photovoltaic power stations.
[0031] In one embodiment, reference Figure 1 A cable assembly includes a cable 100 and a conversion device 200. At least one end of the conversion device 200 is connected to the cable 100. That is, the conversion device 200 can be connected to the cable 100 at one end, at two ends, or at multiple ends. This application has no limitation on this.
[0032] The cable 100 is used to transmit power or information from one place to another, and includes a phase line 110 and a ground line 120 for conducting electricity. In the same cable 100, the number of ground lines 120 is usually one or more, and the number of phase lines 110 is usually two or more, but it can also be one. The phase line 110 and the ground line 120 are both wrapped with an insulating layer 130. The insulating layer 130 can insulate and isolate each phase line 110 and between the phase line 110 and the ground line 120.
[0033] In addition, the insulating layer 130 of the cable 100 may be wrapped with a shielding layer (or armor layer) and an outer sheath layer. The shielding layer can reduce the impact of external electromagnetic fields on the power supply or communication lines, and the armor layer protects the cable from being damaged by external mechanical forces, corroded by chemical gases, etc. The outer sheath layer can play a role in insulation protection.
[0034] refer to Figure 2, the conversion device 200 includes a rotating part 210. The rotating part 210 can rotate and includes a conductive sheet 211. When the rotating part 210 is in the general position, each phase line 110 and the ground line 120 are disconnected. When the rotating part 210 rotates to the predetermined position, the conductive sheet 211 short-circuits each phase line 110 and the ground line 120. At this time, each electrical device can be safely repaired (maintained, replaced, tested, etc.). The general position refers to other positions other than the predetermined position.
[0035] Therefore, when using the power system using the cable assembly of the present application to repair the electrical equipment, it is only necessary to rotate the rotating component 210. Therefore, the cable assembly of the present application can greatly simplify the maintenance process of the power system, thereby improving the maintenance efficiency.
[0036] In one embodiment, reference Figure 1 , the conversion device 200 also includes a connector assembly 220. The connector assembly 220 includes a first connector 221 and a second connector 222. The second connector 222 can be plugged with the first connector 221. Specifically, the first connector 221 can be set as a socket and the second connector 222 can be set as a plug, or the first connector 221 can be set as a plug and the second connector 222 can be set as a socket, etc.
[0037] The rotating component 210 is disposed on the first connector 221. The first connector 221 can be connected to the cable 100, or can be disposed on an electrical device. When it is disposed on an electrical device, the second connector 222 can be connected to the cable 100. Of course, the first connector 221 and the second connector 222 of the connector assembly 220 can also be connected to two different cables 100 respectively.
[0038] refer to Figure 2 , a phase plug 220a and a ground plug 220b are provided on the first connector 221 (or the second connector 222). The phase plug 220a is electrically connected to the corresponding phase line 110, thereby providing power or information transmission for the phase line. The ground plug 220b is electrically connected to the ground wire 120, thereby enabling the ground wire 120 to be connected to the corresponding ground terminal, thereby performing grounding protection. Each phase plug 220a and ground plug 220b may be provided with a mark such as a number or letter, thereby facilitating wiring and maintenance.
[0039] Specifically, the phase plug 220a and the ground plug 220b may be configured as conductive pins, or the phase plug 220a and the ground plug 220b may be configured as conductive pins.
[0040] The first connector 221 is plugged into the second connector 222, and when the rotating component 210 rotates to a predetermined position, the conductive sheet 211 of the rotating component 210 connects the phase line plug 220a and the ground plug 220b, thereby short-circuiting the phase lines 110 and the ground lines 120 of the cables 100 used in the power system.
[0041] At the same time, this embodiment greatly simplifies the wiring and disassembly process of the cable 100 by providing the connector assembly 220. The wiring process only requires plugging the first connector 221 of the connector assembly 220 with the second connector 222, and the wiring removal process only requires unplugging the first connector 221 of the connector assembly 220 from the second connector 222. Therefore, this embodiment can effectively improve the wiring and wiring removal efficiency. In addition, the connector assembly 220 can effectively improve the electrical connection reliability of the power system.
[0042] Of course, in the embodiment of the present application, the configuration of the rotating component 210 may also be different from the above-mentioned configuration. For example, the conversion device 200 may also not include the connector assembly 220, which may be an electrical connector that is fixedly connected between two cables 100 or that is fixedly connected between the cable 100 and the electrical device. In this case, the rotating component 210 is not disposed on the connector assembly 220 that is movably connected, but is disposed on a fixedly connected electrical connector.
[0043] In one embodiment, continue to refer to Figure 2 The conversion device 200 further includes a connector assembly 220. Meanwhile, the rotating component 210 further includes a conductive cylinder 212. The conductive cylinder 212 is used to be sleeved on the grounding plug 220b, and then electrically connected to the ground wire 120.
[0044] It should be noted that the conductive cylinder 212 can be always sleeved on the grounding plug 220b, in which case the rotating component 210 and the grounding plug 220b can be both provided on the same first connector 221. Alternatively, the conductive cylinder 212 can also be sleeved on the grounding plug 220b when the first connector 221 and the second connector 222 are plugged in and matched, in which case the rotating component 210 can be provided on the first connector 221, and the grounding plug 220b can be provided on the second connector 222.
[0045] The conductive sheet 211 is connected to the conductive cylinder 212, and can be electrically connected to the ground plug 220b through the conductive cylinder 212. At this time, when the rotating component 210 rotates to a predetermined position, the short circuit between the phase line 110 and the ground line 120 can be simply and effectively achieved by simply connecting the other end of the conductive sheet 211 to the phase line plug 220a.
[0046] Specifically, refer to Figure 2, the same cable 100 can be provided with three phase lines 110 and one ground line 120. That is, the cable 100 is a three-phase four-wire cable. The corresponding connector assembly 220 is provided with three phase line plugs 220a and one ground plug 220b. At this time, a conductive cylinder 212 sleeved on the ground plug 220b and three conductive sheets 211 connected to the conductive cylinder 212 are provided.
[0047] Alternatively, refer to Figure 3 , the same cable 100 can be provided with two phase lines 110 and two ground lines 120. That is, the cable 100 is a two-phase four-wire cable. The corresponding connector assembly 220 is provided with two phase line plugs 220a and two grounding plugs 220b. Each phase line plug 220a corresponds to a grounding plug 220b to form a plug combination, and each plug combination is insulated and isolated by an insulating partition 223 on the connector assembly 220. At this time, two conductive cylinders 212 can be provided to be respectively sleeved on the two grounding plugs 220b, and each conductive cylinder 212 is connected to a conductive sheet 211.
[0048] Alternatively, refer to Figure 4 , the same cable 100 can be provided with three phase lines 110 and three ground lines 120. That is, the cable 100 is a three-phase six-wire cable. The corresponding connector assembly 220 is provided with three phase line plugs 220a and three grounding plugs 220b. Each phase line plug 220a corresponds to a grounding plug 220b to form a plug combination, and each plug combination is insulated and isolated by an insulating partition 223 on the connector assembly 220. At this time, three conductive cylinders 212 can be provided and respectively sleeved on the three grounding plugs 220b, and each conductive cylinder 212 is connected to a conductive sheet 211.
[0049] In addition, reference Figure 1 In order to facilitate rotation, the rotating component 210 may further include an insulating portion 213, which is disposed on the first connector 221, and the conductive cylinder 212 is fixed on the insulating portion 213, so that the conductive cylinder 212 and the conductive sheet 211 can be rotated together by manually rotating the insulating portion 213. Furthermore, a plurality of protrusions 2131 may be provided on the surface of the insulating portion 213 to increase friction and facilitate hand-held rotation.
[0050] Of course, in other embodiments of the present application, the arrangement of the conductive sheet 211 may be different from the above-mentioned manner. For example, the conductive cylinder 212 connected to the conductive sheet 211 is sleeved on each phase line plug 220a. At this time, when the rotating component 210 rotates to a predetermined position, the other end of the conductive sheet 211 connected to each conductive cylinder 212 is connected to the ground plug 220b.
[0051] In one embodiment, reference Figure 1 The first connector 221 is a socket, and the second connector 222 is a plug. The first connector 221 is provided with an elastic member 220c, and the second connector 222 is provided with a limiting hole 220d. When the first connector 221 and the second connector 222 are plugged together, the elastic member 220c and the limiting hole 220d are snap-fitted, thereby effectively preventing the connection between the first connector 221 and the first connector 221 from being dislocated or falling off due to external force, thereby ensuring the electrical connection stability of the connector assembly 220.
[0052] Of course, when the first connector 221 is a socket and the second connector 222 is a plug, in order to ensure the electrical connection stability of the connector assembly 220, a limiting hole 220d can be provided on the first connector 221 and an elastic member 220c can be provided on the second connector 222. When the first connector 221 and the second connector 222 are plugged in, the elastic member 220c snaps into place with the limiting hole 220d.
[0053] In one embodiment, the conversion device 200 further includes a tightening component 230, which is rotatably connected to the second connector 222. The outer wall of the tightening component 230 is provided with an external thread. The first connector 221 includes a shielding portion 2211, and the inner wall of the shielding portion 2211 is provided with an internal thread adapted to the external thread.
[0054] After the first connector 221 and the second connector 222 are plugged into each other, the tightening component 230 is rotated so that the internal thread and the external thread cooperate with each other, thereby effectively preventing the connection between the first connector 221 and the first connector 221 from being dislocated or falling off due to external force, thereby ensuring the electrical connection stability of the connector assembly 220.
[0055] In one embodiment, continue to refer to Figure 1 , the conversion device 200 further includes a fixing component 240. The fixing component 240 is connected to the first connector 221 and is used to fix the first connector 221. At this time, the first connector 221 is fixed in position, which is more conducive to the stability and safety of the electrical connection. Specifically, the fixing component 240 may be provided with a fixing hole 241, and then the fixing hole 241 may be matched with a connecting piece such as a screw to fix the fixing component 240.
[0056] In one embodiment, a short circuit mark 221a is provided on the first connector 221. An alignment structure 210a is provided on the rotating component 210. When the rotating component 210 rotates until the alignment structure 210a is aligned with the short circuit mark 221a, the phase line 110 and the ground line 120 are short-circuited.
[0057] Meanwhile, in this embodiment, a disconnection mark 221 b is also provided on the first connector 221. When the rotating component 210 rotates until the alignment structure 210 a is aligned with the disconnection mark 221 b, the phase line 110 and the ground line 120 are disconnected.
[0058] In this embodiment, a clear short circuit mark 221a and an open circuit mark 221b are provided on the first connector 221, so that the rotation mode of the rotating component 210 can be standardized, thereby facilitating accurate setting of the circuit in different situations, thereby ensuring the reliability of the circuit connection and the safety of electricity use.
[0059] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
