Description

Technical Field

[0001] This invention relates to the field of power maintenance equipment technology, and in particular to a high-voltage outdoor cable grounding wire connection device. Background Technology

[0002] Currently, when many 10kV distribution line equipment requires power outage maintenance, grounding wires are generally installed at the terminals of 10kV outdoor overhead cables. This is a basic measure to ensure the personal safety of maintenance personnel, and the quality of the grounding wire installation directly affects the level of protection for maintenance personnel. Because the terminals of 10kV outdoor cables are generally quite high, installing and removing grounding wires at the terminals usually requires the assistance of a street light truck. However, due to environmental factors, many tower locations are inaccessible to street light trucks, so workers must climb the towers to perform the work. When installing and removing high-voltage grounding wires on the tower, workers must be a considerable distance away from the pole and extend their arms a long way to properly install or remove a set of grounding wires. This is especially true for inclined cables, where stable installation of grounding wires is difficult, and insufficient force can lead to poor contact. This method of installing grounding wires is not only time-consuming and labor-intensive but also seriously affects work efficiency and quality. Summary of the Invention

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0024] Unless otherwise defined, 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 pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] Example 1:

[0026] Please see Figure 1 and Figure 2This invention provides a high-voltage outdoor cable grounding wire connection device 100 according to a first embodiment of the present invention, used to connect a first cable 70, a second cable 80, and a grounding wire 90. The high-voltage outdoor cable grounding wire connection device includes a first connector 10, a second connector 20 connecting the first connector 10, a first fastener 30, and a second fastener 40. The high-voltage outdoor cable grounding wire connection device 100 of the present invention connects the first connector 10 and the first cable 70 through the first fastener 30, connects the second connector 20 and the second cable 80 through the second fastener 40, and then connects the grounding wire 90 to the first connector 10 or the second connector 20 to realize the installation of the grounding wire 90.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the first connector 10 includes a first fixing part 11 and a first support part 12 connected to the first fixing part 11; the first fixing part 11 is used to connect the first cable 70; the second connector 20 includes a second fixing part 21 and a second support part 22 connected to the second fixing part 21; the second fixing part 21 is used to connect the second cable 80; the end of the second support part 22 away from the second fixing part 21 is connected to the first support part 12; optionally, the junction between the second support part 22 and the first support part 12 is an arc-shaped transition to effectively prevent tip discharge; both the first cable 70 and the second cable 80 are 10kV cables. The first connector 10 and the second connector 20 have the same structure, and the first connector is mainly described below. The first fixing part 11 abuts against the connector of the first cable 70, thereby ensuring an effective contact area; optionally, the first fixing part 11 is provided with a through hole (not shown in the figure). To prevent accidental injury during operation, the end of the first fixing part 11 away from the first support part 12 is arc-shaped. The grounding wire 90 is connected to either the first support portion 12 or the second support portion 22; optionally, the grounding wire 90 is connected at the junction of the first support portion 12 and the second support portion 22 to prevent the grounding wire 90 from moving. In one embodiment, the angle between the second support portion 22 and the first support portion 12 is 90 degrees to 150 degrees. An angle of 120 degrees between the second support portion 22 and the first support portion 12 makes operation easier. To ensure conductivity, both the first connector 10 and the second connector 20 are made of copper. Optionally, both the first connector 10 and the second connector 20 are made of pure copper, which has excellent conductivity, thermal conductivity, corrosion resistance, plasticity, and weldability, making it easy to manufacture and process. It is also suitable for outdoor environments and has a long service life. For a secure connection, the first fixing portion 11, the first support portion 12, the second fixing portion 21, and the second support portion 22 are integrally formed.

[0028] In one embodiment, the first fastener 30 is used to connect the first fixing part 11 and the first cable 70; the second fastener 40 is used to connect the second fixing part 21 and the second cable 80. The first fastener 30 and the second fastener 40 have the same structure, and the first fastener 30 is mainly described below. The first fastener 30 is a bolt; the first fastener 30 passes through the through hole of the first fixing part 11, and then, with the help of a nut, fixes the first fixing part 11 and the first cable 70. The fit between the through hole and the bolt greatly reduces the contact resistance, making the conductivity of the first fixing part 11 better. Since the cable generates heat, if the fault is not eliminated in time, the cable will continue to operate continuously after being energized, resulting in insulation thermal breakdown, causing the cable to trip due to a phase-to-phase short circuit, which may even cause a fire. Therefore, the first fastener 30 is made of shape memory alloy material, and when the abnormal temperature of the first fastener 30 is reached, the first fastener 30 becomes thinner and shorter. When the temperature at the junction of the first cable 70 and the second cable 80 overheats and reaches the abnormal temperature of the first fastener 30, the first fastener 30 deforms due to heat, causing the first cable 70 and the first connector 10 to separate, thereby cutting off power and protecting the equipment and operator safety. Optionally, the first fastener 30 is made of a copper-zinc alloy. In other embodiments, the first fastener 30 is made of copper-aluminum-nickel alloy, copper-molybdenum-nickel alloy, copper-gold-zinc alloy, etc.

[0029] This high-voltage outdoor cable grounding wire connection device 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 first fixing part 11. The current sensor is used to measure the current flowing through the first cable 70 and the second cable 80. The alarm is built into the controller. The controller is connected to the current sensor and the alarm 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 cable 70 and the second cable 80 is greater than a set value, the alarm sounds, promptly reminding the operator. Further, the control mechanism also includes a thermometer. The thermometer is built into the first fixing part 11. The thermometer is used to measure the temperature of the first cable 70. The controller is connected to the thermometer and the alarm respectively. The controller is used to control the operation of the thermometer. When the thermometer measures that the temperature of the first cable 70 is greater than a set value, the alarm sounds, promptly reminding the operator.

[0030] In use, the first fixing part 11 and the first cable 70 are connected by the first fastener 30, and the second fixing part 21 and the second cable 80 are connected by the second fastener 40. Then, the grounding wire 90 is connected to the first support part 12 or the second support part 22 to realize the installation of the grounding wire 90. Therefore, when installing and removing the grounding wire 90, the operator does not need to be far away from the pole or extend their hands outwards to install and remove a set of grounding wires. The installation and removal of the grounding wire can be easily completed while standing on the pole, which greatly improves work efficiency, reduces the difficulty of installation and removal, saves time and economic costs, reduces safety risks, greatly reduces the probability of poor contact due to failure to tighten screws, and strengthens the stability and robustness of the structure.

[0031] The high-voltage outdoor cable grounding wire mounting device 100 of the present invention connects the first fixing part 11 and the first cable 70 through the first fastener 30, and the second fixing part 21 and the second cable 80 through the second fastener 40. The grounding wire 90 is then connected to the first support part 12 or the second support part 22 to achieve the installation of the grounding wire 90. This high-voltage outdoor cable grounding wire mounting device 100 is easy to operate, shortens operation time, improves efficiency, and enhances safety.

In one embodiment, the first support portion 12a includes a first sleeve 121a and a first telescopic portion 122a connected to the first sleeve 121a; one end of the first telescopic portion 122a is connected to the first fixing portion 11a; the second support portion 22a includes a second sleeve 221a and a second telescopic portion 222a connected to the second sleeve 221a; the second sleeve 221a is connected to the first sleeve 121a; one end of the second telescopic portion 222a is connected to the second fixing portion 21a.
