Detailed Description
In order that the invention may be more fully understood, reference will now be made to the following description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The first embodiment is as follows:
referring to fig. 1 and fig. 2, a high voltage outdoor cable ground wire hanging ring 100 according to an embodiment of the present invention is used for connecting a first cable 70, a second cable 80 and a ground wire 90; the high-voltage outdoor cable grounding wire hanging ring 100 comprises a mounting piece 10 and a fastener 20; the high-voltage outdoor cable grounding wire hanging ring 100 of the invention connects the first cable 70, the second cable 80 and the mounting piece 10 through the fastener 20, and then connects the grounding wire 90 to the mounting piece 10, thus realizing the mounting of the grounding wire 90.
As shown in fig. 1 and 2, in the present embodiment, the mounting member 10 includes a fixing portion 11, a supporting portion 12 connected to the fixing portion 11, and a hanging portion 13 connected to the supporting portion 12; the fixing portion 11 is used for connecting the first cable 70 and the second cable 80; alternatively, the fixing portion 11 abuts against the joint of the first cable 70 or the second cable 80, ensuring an effective contact area; the fixing portion 11 is provided with a through hole (not shown). In order to prevent accidental injury during operation, one end of the fixing part 11, which is far away from the supporting part 12, is arc-shaped; the first cable 70 and the second cable 80 are both 10kV cables. The support portion 12 is used for drawing the joint of the first cable 70 and the second cable 80 to the operator for installing the grounding wire 90; the suspension portion 13 is used for connecting the ground wire 90; the hanging portion 13 is a closed loop to prevent the ground wire 90 from slipping off. Optionally, the included angle between the fixing portion 11 and the supporting portion 12 is 60 degrees to 120 degrees; furthermore, the included angle between the fixing portion 11 and the supporting portion 12 is 90 degrees, so as to ensure that the insulating rod of the ground wire 90 is perpendicular to the joint of the first cable 70 and the second cable 80, thereby ensuring the installation effect of the ground wire 90. In one embodiment, the suspension 13 is a circular ring, which effectively prevents the tip discharge. In other embodiments, the hanging portion 13 is triangular, rectangular, or the like. In order to ensure the conductive effect, the fixing portion 11, the supporting portion 12 and the hanging portion 13 are made of copper. Optionally, the fixing portion 11, the supporting portion 12 and the hanging portion 13 are made of red copper, so that the fixing portion has good electrical conductivity, thermal conductivity, corrosion resistance, plasticity and weldability, is convenient to produce and process, and is suitable for outdoor environment and long in service life. The fixing portion 11, the supporting portion 12 and the hanging portion 13 are integrally formed for firm connection.
In one embodiment, the fastener 20 is used to connect the fixing portion 11, the first cable 70 and the second cable 80. Optionally, the fastener 20 is a bolt; the fastener 20 penetrates through the through hole of the fixing portion 11, and the fixing portion 11, the first cable 70 and the second cable 80 are fixed by matching with the nut, and the through hole and the bolt are matched, so that the contact resistance is greatly reduced, and the electric conductivity of the fixing portion 11 is better. After the cable generates a heating phenomenon, if the fault is not cleared in time, the cable generates an insulation thermal breakdown phenomenon after continuously electrifying operation, so that the inter-phase short circuit trip phenomenon of the cable is caused, and a fire disaster is possibly caused seriously, therefore, the fastening piece 20 is made of the memory alloy material, and when the metamorphosis temperature of the fastening piece 20 is reached, the fastening piece 20 becomes thin and short. When the temperature of the joint of the first cable 70 and the second cable 80 is too high and reaches the transformation temperature of the fastener 20, the fastener 20 is deformed by heat to separate the first cable 70, the second cable 80 and the mounting member 10, so that the power is cut off and the safety of equipment and operators is protected. Alternatively, the fastener 20 is made of copper-zinc alloy. In other embodiments, the fastener 20 is made of copper-aluminum-nickel alloy, copper-molybdenum-nickel alloy, copper-gold-zinc alloy, or the like.

Optionally, the alarm is a buzzer. When the current sensor measures that the current flowing through the first cable 70 and the second cable 80 is larger than a set value, the alarm gives an alarm to remind an operator in time. Further, the control mechanism also comprises a temperature detector; the thermometer is arranged in the fixed part 11; the thermometer is used for measuring the temperature of the joint of the first cable 70 and the second cable 80; the controller is respectively in signal connection with the temperature detector and the alarm; the controller is used for controlling the operation of the temperature detector. When the temperature of the joint of the first cable 70 and the second cable 80 measured by the temperature detector is greater than a set value, the alarm gives an alarm to remind an operator in time.
In use, the first cable 70, the second cable 80, and the fixing portion 11 of the mounting device 10 are connected by the fastener 20, and the ground wire 90 is connected to the suspension portion 13, thereby mounting the ground wire 90. Therefore, when the grounding wire 90 is assembled and disassembled, the part on the body of an operator can be assembled and disassembled without a long distance from the rod and without a long distance from the hand to the outside, the assembly and disassembly of the grounding wire can be easily completed by standing on a tower, the working efficiency is greatly improved, the difficulty of the assembly and disassembly is reduced, the assembly and disassembly time cost and the economic cost are saved, the safety risk is reduced, the probability of the problem of poor contact caused by the fact that the screw cannot be screwed down is greatly reduced, and the stable firmness of the structure is enhanced.
The high-voltage outdoor cable grounding wire hanging ring 100 of the invention connects the first cable 70, the second cable 80 and the mounting piece 10 through the fastener 20, and then connects the grounding wire 90 to the hanging part 13, thereby realizing the mounting of the grounding wire 90.
