Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance operation equipment, in particular to a high-voltage outdoor cable grounding wire hanging ring. Background Art

[0002] Currently, when many 10kV distribution line equipment requires power outages for maintenance, ground wires are typically installed at the terminals of 10kV outdoor overhead line cables for safety reasons. Because these terminals are typically high, installing and removing the ground wires from these terminals typically requires the use of a streetlight truck. Furthermore, workers must stand on the truck to ensure that the ground wire's insulator contacts the lead wire at a 90-degree angle, ensuring proper installation and removal. However, due to environmental and locational constraints, many power towers are inaccessible to streetlight trucks, forcing workers to climb the towers to perform the installation. When installing and removing high-voltage ground wires from a tower, workers must stand a considerable distance from the pole and extend their hands far outward to install and remove a set of ground wires. This makes installation and removal very difficult, and the resulting lack of strength makes it difficult to tighten the wires, resulting in poor contact. This method of attaching and removing ground wires is not only time-consuming and labor-intensive, but also severely impacts work efficiency and quality. Summary of the Invention

[0024] To facilitate understanding of the present invention, the present invention will be described more fully below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Example 1:

[0027] See also Figure 1 and Figure 2 , which is an embodiment of the present invention, a high-voltage outdoor cable grounding wire hanging ring 100 is used to connect a first cable 70, a second cable 80 and a grounding wire 90; the high-voltage outdoor cable grounding wire hanging ring 100 includes a mounting member 10 and a fastener 20; the high-voltage outdoor cable grounding wire hanging ring 100 of the present invention connects the first cable 70, the second cable 80 and the mounting member 10 through the fastener 20, and then connects the grounding wire 90 to the mounting member 10 to achieve the installation of the grounding wire 90.

[0028] like Figure 1 and Figure 2As shown, in this 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 to connect the first cable 70 and the second cable 80; optionally, the fixing portion 11 abuts against the joint of the first cable 70 or the second cable 80 to ensure an effective contact area; the fixing portion 11 is provided with a through hole (not marked in the figure). In order to prevent accidental injury during operation, the end of the fixing portion 11 away from the supporting portion 12 is arc-shaped; the first cable 70 and the second cable 80 are both 10kV cables. The supporting portion 12 is used to shorten the distance between the junction of the first cable 70 and the second cable 80 and the operator in order to install the grounding wire 90; the hanging portion 13 is used to connect the grounding wire 90; the hanging portion 13 is a closed loop to prevent the grounding wire 90 from slipping. Optionally, the angle between the fixing portion 11 and the supporting portion 12 is 60 degrees to 120 degrees; further, the angle between the fixing portion 11 and the supporting portion 12 is 90 degrees, ensuring that the insulating rod of the grounding wire 90 is perpendicular to the junction of the first cable 70 and the second cable 80, so as to ensure the installation effect of the grounding wire 90. In one embodiment, the hanging portion 13 is a circular ring, which effectively prevents tip discharge. In other embodiments, the hanging portion 13 is a triangle, a rectangle, etc. In order to ensure the conductive effect, the fixing portion 11, the supporting portion 12 and the hanging portion 13 are all made of copper. Optionally, the fixing portion 11, the supporting portion 12 and the hanging portion 13 are all made of red copper, which has good electrical conductivity, thermal conductivity, corrosion resistance, plasticity and weldability, is easy to produce and process, and is suitable for outdoor environments and has a long service life. In order to ensure a firm connection, the fixing portion 11, the supporting portion 12 and the hanging portion 13 are integrally formed.

[0029] 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 a through-hole in the fixing portion 11 and, in conjunction with a nut, secures the fixing portion 11, the first cable 70, and the second cable 80. The combination of the through-hole and the bolt significantly reduces contact resistance, improving the electrical conductivity of the fixing portion 11. If the cable heats up and the fault is not promptly corrected, continued operation with power to the cable can lead to insulation thermal breakdown, causing a phase-to-phase short circuit and tripping, which can seriously cause a fire. Therefore, the fastener 20 is made of a memory alloy. When the fastener 20 reaches its transformation temperature, it becomes thinner and shorter. When the junction of the first and second cables 70, 80 overheats and reaches the transformation temperature of the fastener 20, the fastener 20 deforms due to the heat, separating the first and second cables 70, 80, and the mounting member 10, thereby disconnecting the power supply and protecting the equipment and the operator. Optionally, the fastener 20 is made of a copper-zinc alloy. In other embodiments, the fastener 20 is made of a copper-aluminum-nickel alloy, a copper-molybdenum-nickel alloy, a copper-gold-zinc alloy, or the like.

[0030] The high-voltage outdoor cable grounding wire hanging ring 100 also includes a control mechanism (not shown), which includes a current sensor, an alarm, and a controller. The current sensor is built into the fixing portion 11 and is used to measure the current flowing through the first and second cables 70 and 80. The alarm is built into the controller and is connected to the current sensor and alarm signals respectively. The controller is used to control the operation of the current sensor and the alarm. Optionally, the alarm is a buzzer. When the current sensor measures that the current flowing through the first and second cables 70 and 80 is greater than a set value, the alarm sounds, promptly alerting the operator. Furthermore, the control mechanism also includes a thermometer. The thermometer is built into the fixing portion 11 and is used to measure the temperature at the junction of the first and second cables 70 and 80. The controller is connected to the thermometer and alarm signals respectively. The controller is used to control the operation of the thermometer. When the thermometer measures that the temperature at the junction of the first and second cables 70 and 80 is greater than a set value, the alarm sounds, promptly alerting the operator.

[0031] During use, the first cable 70, the second cable 80, and the fixing portion 11 of the mounting member 10 are connected by the fastener 20, and then the grounding wire 90 is connected to the hanging portion 13 to achieve the installation of the grounding wire 90. Therefore, when installing and removing the grounding wire 90, the operator does not need to move his upper body far away from the pole or extend his hands far outward to install and remove a set of grounding wires. The grounding wire can be easily installed and removed while standing on the pole tower, which greatly improves work efficiency, reduces the difficulty of installation and removal, saves installation and removal time and economic costs, reduces safety risks, greatly reduces the probability of poor contact problems caused by failure to tighten screws, and enhances the stability and firmness of the structure.

[0032] The high-voltage outdoor cable grounding wire hanging ring 100 of the present invention connects the first cable 70, the second cable 80, and the mounting member 10 via the fastener 20, and then connects the grounding wire 90 to the hanging portion 13 to achieve the installation of the grounding wire 90. The high-voltage outdoor cable grounding wire hanging ring 100 is easy to operate, shortens operation time, improves operation efficiency, and enhances safety.

[0033] Example 2:

[0034] See also Figure 3 and Figure 4 , another embodiment of the present invention is a high-voltage outdoor cable grounding wire hanging ring 100a. This embodiment is similar to the high-voltage outdoor cable grounding wire hanging ring 100 of the previous embodiment, except that the hanging portion 13a of this embodiment is slidably mounted on the support portion 12a to adjust the distance between the hanging portion 13a and the fixed portion 11a. Optionally, the hanging portion 13a and the support portion 12a are connected by threads.

[0035] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0036] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
