[0046] See also Figure 1 , Figure 2An embodiment of the present application provides a conductive plug for grounding, the conductive plug 11 comprising a plug-in section 111 and a connecting section 112 connected to one end of the plug-in section 111; the plug-in section 111 is used to be plugged into a conductive base 10, and a clamping hole 1113 is provided on the plug-in section 111 for cooperating with a clamping assembly 12 on the conductive base 10, and the connecting section 112 is used to be connected to a grounding end of a grounding wire.
[0047] Exemplarily, the plug section 111 and the connecting section 112 are both bar-shaped structures, and one end of the plug section 111 is connected to one end of the connecting section 112 to roughly form an L-shaped structure. In order to ensure the reliability of the connection, the plug section 111 and the connecting section 112 are an integrally formed structure; in order to ensure the conductive performance, the plug section 111 and the connecting section 112 are made of copper. For example, the plug section 111 and the connecting section 112 are machined from brass.
[0048] The plug-in section 111 is used to connect with the conductive seat 10, and the connecting section 112 is used to connect with the grounding end of the grounding wire. The conductive seat 10 is used to be fixed on the grounding copper bus. Exemplarily, the conductive seat 10 is provided with a slot 101 for inserting the plug-in section 111 and a clamping assembly 12 for pressing the plug-in section 111 in the slot 101, and the plug-in section 111 is provided with a clamping hole 1113 for matching with the clamping assembly 12. After the plug-in section 111 is inserted into the slot 101 of the conductive seat 10, the clamping assembly 12 is controlled and its end is pressed against the clamping hole 1113, and then the plug-in section 111 is pressed into the slot 101 of the conductive seat 10, which not only realizes a reliable connection between the plug-in section 111 and the conductive seat 10, but also plays a limiting role to avoid the plug-in section 111 from being pulled out of the slot 101 during the connection process.
[0049] When the power equipment in the power plant is shut down for maintenance, the conductive plug 11 and the conductive seat 10 provided in the embodiment of the present application can be used to ground the power equipment. The specific grounding process is as follows: Figure 3 , Figure 4 First, the conductive base 10 is fixedly connected to the grounding copper busbar, and the connecting section 112 of the conductive plug 11 is fixedly connected to the grounding end of the grounding wire; then, the plug-in section 111 of the conductive plug 11 is inserted into the slot 101 of the conductive base 10, and the end of the clamping assembly 12 is pressed against the clamping hole 1113 to clamp the plug-in section 111; then, the conductor end of the grounding wire is clamped on the conductor of the power equipment with a grounding wire pliers, thereby realizing reliable grounding of the power equipment.
[0050] When the maintenance of the power equipment in the power plant is completed, the grounding clamp is first removed from the conductor of the power equipment, and then the clamping force on the plug-in section 111 is removed through the clamping assembly 12, and then the plug-in section 111 is pulled out of the slot 101 to separate the conductive plug 11 from the conductive seat 10, thereby realizing the grounding of the power equipment.
[0051] Therefore, the conductive plug 11 provided in the embodiment of the present application is used to be connected to the grounding end of the grounding wire, and is plugged into the conductive base 10 fixed to the grounding copper busbar. The plug-in section 111 of the conductive plug is compressed by the clamping assembly 12 on the conductive base 10, so that the conductive plug 11 and the conductive base 10 are reliably connected together, thereby achieving a firm and reliable connection between the grounding end of the grounding wire and the grounding copper busbar. Compared with directly fixing the grounding end of the grounding wire to the grounding copper busbar with bolts, the risk of the grounding end of the grounding wire becoming loose is reduced, and the reliability of grounding is improved.
[0052] In some embodiments, see Figure 1 , Figure 2 The plug-in section 111 includes a first surface 1111 and a second surface 1112 that are arranged opposite to each other, a pressing hole 1113 runs through the first surface 1111 and the second surface 1112, and an anti-slip pattern 1114 is arranged on the second surface 1112. During operation, the first surface 1111 of the plug-in section 111 is firstly directed toward the pressing assembly 12, and then the plug-in section 111 is inserted into the slot 101 of the conductive seat 10, and then the end of the pressing assembly 12 is pressed against the pressing hole 1113 to press the plug-in section 111 into the slot 101, so that the second surface 1112 of the plug-in section 111 is in close contact with the inner surface of the slot 101, and the anti-slip pattern 1114 arranged on the second surface 1112 increases the friction between the second surface 1112 and the inner surface of the slot 101, thereby improving the reliability of the connection between the conductive plug 11 and the conductive seat 10.
[0053] In some embodiments, see Figure 1 , Figure 2 The plug-in section 111 includes a first side surface 1115 on which a locking groove 1116 is disposed. The plug-in section 111 includes a second side surface 1117 on which a locking groove 1118 is disposed.
[0054] Exemplarily, a locking indexing pin 13 is provided on the conductive seat 10, and the pin head of the locking indexing pin 13 is used to lock with the locking groove 1116; an electromagnetic lock 14 is provided in the conductive seat 10, and the lock head of the electromagnetic lock 14 is used to lock with the locking groove 1118. During operation, when the plug-in section 111 is inserted into the slot 101 of the conductive seat 10 and is pressed by the pressing assembly 12, the pin head of the locking indexing pin 13 is controlled to be inserted into the locking groove 1116, and the lock head of the electromagnetic lock 14 is controlled to be inserted into the locking groove 1118, so as to lock the plug-in section 111, avoid the plug-in section 111 from being pulled out under the action of external force, and further improve the reliability of grounding.
[0055] In some embodiments, see Figure 1 , Figure 2The end surface of the plug section 111 away from the connecting section 112 is an outwardly protruding arc surface. By setting the end surface of the plug section 111 away from the connecting section 112 as an outwardly protruding arc surface, it can play a guiding role, so that the plug section 111 can be quickly inserted into the slot 101 of the conductive seat 10, thereby improving work efficiency.
[0056] The connecting section 112 can be connected to the ground end of the ground wire by welding. Figure 2 , the connecting section 112 has a bolt hole 1121 extending therethrough. Thus, the connecting section 112 can be connected to the grounding end of the grounding wire by means of a bolt. For example, a copper nose is first fixed to the grounding end of the grounding wire, and then a bolt is passed through the copper nose and the bolt hole 1121 on the connecting section 112 in sequence, and then a nut is screwed onto the end of the bolt. After the nut is tightened, the connecting section 112 is firmly connected to the grounding end of the grounding wire. In some embodiments, see Figure 1 , a positioning groove 1122 is provided on the connecting section 112. During operation, the copper nose can be placed in the positioning groove 1122 to limit the copper nose, and then the connecting section 112 and the copper nose are connected together by bolts.
[0057] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
