Description

Technical Field

[0001] The present application relates to the technical field of high-altitude operations on power lines, and in particular to an automatic short-circuiting device for a conductor shield and a conductor short-circuiting method. Background Art

[0002] At present, in the field of power engineering, with the continuous expansion of the scale of power grids and the growing demand for power transmission, the layout of conductors has become more and more complex and diverse. Especially in some high-voltage transmission lines, the method of splitting conductors within phases is often used to increase transmission capacity and improve transmission efficiency. However, this structure also brings a series of technical problems.

[0003] During normal operation, due to factors such as manufacturing process, installation errors, and operating environment, there may be an imbalance in the current load between the split conductors in the phase. This will cause the bolts of the drain plate to gradually loosen under long-term unbalanced force, which will in turn cause unequal potentials between the conductors. The existence of potential difference will cause abnormal current flow between the conductors, generating additional heat, which will not only accelerate equipment aging and reduce equipment service life, but may also affect the stability of power supply and even cause power outages, posing a serious threat to the safe and reliable operation of the power system.

[0004] When facing ice and snow disasters, it is necessary to melt the ice on the conductors. If the split conductors in the phase cannot be effectively short-circuited, the melting current cannot be evenly distributed on the conductors, which will cause overcurrent in some conductors, thereby causing ablation and damaging the conductors, seriously affecting the normal operation of the transmission line, causing huge economic losses and social impacts.

Specifically, the first flat belt channel 312 connects the shield head and the flat belt sleeve, and realizes clamping and guiding.

[0051] Preferably, see Figures 4 to 6 The middle connecting member 32 is composed of a plurality of shield sections 321, and the plurality of shield sections 321 are connected in pairs to form a second flat belt channel 322 for the guide rail component 10 to pass through. The shield section 321 is also provided with a connecting plate body 323, and the connecting plate body 323 is used to fix the wire connecting member 40 relative to the shield section 321.

[0052] Preferably, multiple shield segments 321 are hingedly connected via a set pin seat 34, and the head connector 31 is hinged to the shield segment 321 at the end, that is, the shield head and the shield segment 321 are connected via the set pin seat 34, and the tail connector 33 is hinged to the shield segment 321 at the other end, and the tail connector 33 is specifically a shield seat, and the shield seat is also provided with a pin seat 34, so that the shield seat and the shield segment 321 are hinged via the set pin seat 34; the hinge points between the shield segments 321, the hinge points between the shield segments 321, and the hinge points between the shield segments 321 and the head connector 31 and the tail connector 33 are all provided with a rotation space greater than the first angle, and the first angle is preferably 180 degrees, so as to facilitate the shield segment 321 to complete the rotation, for example Figure 8 shown.

[0053] Preferably, the shield section 321 and the shield seat are both aluminum parts, the connecting plate 323 is specifically an adhesive plate, and then the wire connector 40 is bonded to the connecting plate 323, and the flat copper wire is bonded to the side of the shield section 321, and the extension direction of the wire connector 40 is consistent with the extension direction of the connection of multiple shield sections 321.

As the conductor shield automatic short-circuiting device 1 gradually climbs and moves, the flat copper soft wire gradually fits the conductor A3 and the conductor B4 as a whole to complete the short-circuit.

[0056] Furthermore, the present application also provides a method for short-circuiting a conductor 2, which is applicable to any one of the above-mentioned conductor shield automatic short-circuiting devices 1, and the method for short-circuiting a conductor 2 includes:

[0057] Step S100: using a projectile device to throw the guide rail component 10 onto the wire 5 to be short-circuited, so as to form a channel between the ground 7 and the wire 2;

[0058] Step S200: connecting the driving mechanism 20 to the shield assembly 30 and making the shield assembly 30 and the guide rail component 10 interlocked;

[0060] Step S400: the shield assembly 30 guides the conductor connector 40 to establish a conductive channel between the conductors 2 that are split and arranged in each phase to achieve a short-circuit connection.

[0061] See Fig. 9 The conductor 2 is specifically a four-phase split conductor 2.

At E, the conductor shield automatic short-circuiting device 1 moves to a position where the flat copper wire can be short-circuited, and the flat copper wire is gradually laid on the conductor 2 for short-circuiting, and then the transition occurs at F, where the conductor shield automatic short-circuiting device 1 completes the short-circuiting operation of the four split conductors 2 in the phase. Fig. 9 A, B, C, D, E, and F are status scenes that are performed in sequence and have a chronological order.

[0062] Further preferably, the wire 2 short-circuiting method can also be applied to the short-circuiting connection between the wires 2 arranged between the phases outside the phase, see Fig.10 The conductor 2 short-circuiting method also includes: before step S300, it includes: connecting multiple conductor shield automatic short-circuiting devices 1 on the conductor 2 set between phases outside the phase with a short-circuiting conductor 5; after the electrical test, the conductor shield automatic short-circuiting device 1 located at one end is grounded to the grounding wire 6, and at the same time, multiple conductor shield automatic short-circuiting devices 1 are controlled to climb to perform short-circuiting connection of the conductor 2 split in the phase.

The specific operation is to hang the grounding wire 6 and the shorting wire 5 set at intervals, and then climb up to make a short-circuit connection, so as to realize the automatic hanging of the shorting grounding wire 6. It should be noted that the electricity must be tested before hanging the ground to prevent the occurrence of malicious misoperation accidents.

At the same time, the driving motor 25 is also provided with a driving motor mounting base plate 254 and a driving motor transition flange plate 255 to further improve the connection stability between the driving motor 25 and the body of the driving mechanism 20, and to prevent the driving mechanism 20 from shaking during the lifting process.

[0066] Furthermore, since the conductor connector 40 and the conductor 2 split in the phase are overlapped, the first width set by the guide rail component 10 is matched with the setting parameters of the conductor shield automatic short-circuiting device 1 to determine the flow area of ​​the conductor connector 40 and the conductor 2 split in the phase. Therefore, in a specific use method, the preferred setting parameters of the conductor shield automatic short-circuiting device 1 and the first width of the flat belt selected under a specific working condition are provided. The setting parameters are preferably: conductor 2LGJ-630 / 45, cross-sectional area 630 square millimeters, diameter 33.6mm, line density 2.06kg / m. The phase spacing of conductor 2 is considered as 15m. The ice melting current is 3000 amperes. The pressing force is 3kN, and the flow capacity is 1.5A / square millimeter. Consider the crimping of 20 square centimeters (40*50).

[0067] Preferably, the climbing drive calculation of the drive mechanism 20: the three-phase vertical climbing drag weight is 30 meters of wire 2 and the weight of three climbing mechanisms (considering 12kg for each) totaling 96kg, and each load is 32kg. The design climbing speed is 18 meters / minute (0.3m / s). Climbing power consumption: 96 watts. Therefore, a DC 24V120-watt worm gear reduction motor is selected. The mating drive gear has 1.5 modules and 20 teeth, an outer diameter of 33mm, and a gear speed of 173 rpm. Wire clamping drive calculation: In order to ensure the overcurrent capacity and protect the wire 2, the maximum clamping force is designed to be 4kN, so the driving force of the gear rack is 4kN. The gear rack is designed to be 1.5 modules and 14 teeth. The outer diameter is 24mm and the pitch circle is 21mm. Its torque is: 42Nm. A DC 24V120-watt worm gear reduction motor is selected, and the gear speed is 18 rpm.
