Description

Technical Field

[0001] The present application relates to the technical field of electric power maintenance, and in particular to a storage bag for a grounding wire. Background Art

[0002] Pumped storage, also known as energy storage power generation, utilizes electricity generated during periods of low power load to pump water to an upper reservoir. During peak periods, the stored water is then released to a lower reservoir for power generation. This technology converts excess power during periods of low power load into high-value energy during periods of high power load. It is suitable for frequency and phase modulation, can be used to stabilize the power system's frequency and voltage, and is suitable for emergency standby. It can also improve the efficiency of thermal and nuclear power plants within the power system.

[0019] During routine maintenance of pumped storage power stations, isolation measures need to be implemented. During the maintenance of electrical equipment, grounding wires need to be installed. Grounding wires are usually stored or transferred in storage bags. However, existing storage bags make the conductors and branches of the grounding wires prone to entanglement and knotting, which makes it extremely inconvenient to disassemble and assemble the grounding wires, increases the workload of personnel, and easily causes damage to the grounding wires. Therefore, a simpler and more efficient storage bag for grounding wires is urgently needed.

[0020] Below, through specific embodiments and combined Figures 1 to 3 The technical solution of this application is further described in detail.

[0021] In some embodiments of the present application, a storage bag for a ground wire is provided, such as Figures 1 to 3 As shown, the grounding wire includes a grounding terminal 1-1, a conductor 1-2 and multiple branches 1-3 connected in sequence, and each branch 1-3 is connected to an insulating rod 1-4; the storage bag includes a rectangular bag body 2, and the bag body 2 includes a first surface and a second surface opposite to each other; the first surface is provided with multiple rod clips 2-1, multi-strand wire clips 2-2, single-strand wire clips 2-3 and end clips 2-4, each of the rod clips 2-1 is used to clamp one of the insulating rods 1-4, the multi-strand wire clips 2-2 are used to clamp the intersection of the multiple branches 1-3, the single-strand wire clips 2-3 are used to clamp the conductor 1-2, and the end clips 2-4 are used to clamp the grounding terminal 1-1; a first Velcro hook surface 2-5 is provided on each of the opposite sides along the length direction; the second surface is provided with a full-surface first Velcro fur surface; the bag body 2 has a first state of full expansion and a second state of winding, and one of the first Velcro hook surfaces 2-5 in the second state is bonded to the first Velcro fur surface.

[0022] like Figures 1 to 3 As shown in the figure, the L direction is the length direction of the bag body 2, and the W direction is the width direction of the bag body 2.

[0023] The grounding wire is, for example, a 10kV transformer grounding wire. Figure 1 As shown, for example, it includes three insulating rods 1-4, three branch lines 1-3, a conductor 1-2, and a grounding terminal 1-1. Insulating rods 1-4 are 0.5 meters long, and both branch lines 1-3 and conductor 1-2 are copper wires. Branch line 1-3 is 1 meter long, and conductor 1-2 is 2 meters long. The grounding wire works by connecting the three phases of the maintenance equipment to the ground through a three-phase short-circuit grounding wire to achieve equipotentiality, preventing the risk of sudden power outages.

[0024] The bag body 2 is, for example, a rectangular canvas of 110 cm * 70 cm. The rod clip 2-1, the multi-strand wire clip 2-2, and the single-strand wire clip 2-3 are, for example, plastic or rubber C-shaped clips, and the end clip 2-4 is, for example, a metal C-shaped clip, all of which are fixed to the bag body 2, for example, by sewing, riveting, etc.; by arranging the rod clip 2-1, the multi-strand wire clip 2-2, the single-strand wire clip 2-3, and the end clip 2-4 to be respectively clamped with corresponding parts of the ground wire, the ground wire can be firmly installed in the storage bag to avoid entanglement or knotting; Figure 1 As shown, when the storage bag is in the first state, the ground wire can be detachable.

[0025] like Figure 1 As shown, the two short sides of the first side of the bag body 2 are respectively provided with a first Velcro hook surface 2-5, and the entire second side of the bag body 2 is provided with a first Velcro fur surface, and the first Velcro fur surface can be the same size as the second side; Figure 3 As shown, the bag body 2 is rolled up so that the first Velcro hook surface 2-5 is bonded to any position of the first Velcro fleece surface, so that the storage bag is in the second state, which is approximately cylindrical in shape, convenient for transfer, and has a strong protective effect; two first Velcro hook surfaces 2-5 are provided, so that no matter whether it is rolled in a clockwise direction or a counterclockwise direction, it can be ensured that one first Velcro hook surface 2-5 is bonded to the first Velcro fleece surface.

[0026] The storage bag for the grounding wire has a simple structure, is convenient for disassembling and assembling the grounding wire, has high efficiency, strong stability and good safety.

[0027] This grounding cable storage bag is compact and lightweight, making it easy to carry and suitable for various scenarios. It avoids the tangling and knotting that can occur with traditional storage bags before use, improving work efficiency. The bag's flattened design effectively prevents friction between the grounding cable and the ground during installation and removal, reducing wear and extending the cable's service life. When installing the grounding cable, terminal card 2-4 can also be equipped with a voice module. When grounding terminal 1-1 is removed, a voice message is triggered, playing instructions for installing the grounding cable, reminding the operator and preventing any misoperation.

[0028] In some embodiments, as Figure 1 As shown, the first surface is provided with multiple groups of single-strand line cards at intervals along the width direction, and each group of single-strand line cards includes multiple single-strand line cards 2-3 arranged at intervals along the length direction, and each of the single-strand line cards 2-3 is respectively clamped to a section of the wire 1-2 so that the wire 1-2 is arranged in a serpentine shape.

[0029] like Figure 1 As shown, the single-strand line cards 2-3 are arranged in groups, so that the wires 1-2 can be connected to the single-strand line cards 2-3 along a serpentine arrangement, thereby avoiding entanglement of the wires 1-2 and greatly improving space utilization.

[0030] In some embodiments, as Figure 1 As shown, there are three rod cards 2-1, located in the middle of the left side of the first surface; the single-strand line cards 2-3 include two groups, each group includes three single-strand line cards 2-3, located in the lower middle part of the right side of the first surface; there are two multi-strand line cards 2-2, located in the middle of the bottom end of the first surface; there is one end card 2-4, located at the top right side of the first surface. Figure 1 As shown, while ensuring the stability of the grounding wire, the space utilization of the bag body 2 can be greatly improved, making the storage bag lighter.

[0031] In some embodiments, as Figure 2 As shown, the first surface is provided with a whole second Velcro surface, and the rod card 2-1, the multi-strand wire card 2-2, the single-strand wire card 2-3 and the end card 2-4 are all located on the side of the second Velcro surface away from the first surface; the second surface is provided with a second Velcro hook surface 2-6 on both sides opposite to each other along the length direction, and one of the second Velcro hook surfaces 2-6 in the second state is bonded to the second Velcro surface.

[0032] like Figure 2 As shown, a second Velcro hook surface 2-6 is respectively provided on the two short sides of the second surface, and the second Velcro hook surface 2-6 can be the same as the first Velcro hook surface 2-5; a second Velcro fleece surface is provided on the entire first surface of the bag body 2, and the second Velcro fleece surface can be the same size as the first surface; in this way, after the bag body 2 is rolled up, not only can a first Velcro hook surface 2-5 on the first surface be bonded to the first Velcro fleece surface on the second surface, but at the same time, a second Velcro hook surface 2-6 on the second surface can also be bonded to the second Velcro fleece surface on the first surface, thereby further improving the stability of the storage bag.

[0033] In some embodiments, as Figure 3 As shown, a handle 2-7 is connected to the middle of the second surface to facilitate the transfer of the storage bag.

[0034] In some embodiments, the storage bag needs to be flattened when installing or removing the ground wire.

[0035] When installing the grounding wire, remove the grounding terminal 1-1 from the terminal card 2-4, remove the conductor 1-2 from the single-strand wire card 2-3, connect the grounding terminal 1-1 to the equipment grounding pile, then remove the three branches 1-3 from the multi-strand wire card 2-2, remove the insulating rod 1-4 from the rod card 2-1, and connect the insulating rod 1-4 to the maintenance equipment to complete the grounding isolation.

[0036] When removing the grounding wire, first remove the three insulating rods 1-4 on the maintenance equipment, then remove the grounding terminal 1-1 from the grounding pile. At this time, you need to flatten the storage bag, first install the insulating rods 1-4 on the rod clamp 2-1, straighten the branch line 1-3 along the three insulating rods 1-4, and clamp the intersection of the three branch lines 1-3 on the multi-strand wire clamp 2-2, and clamp the subsequent wire 1-2 along the serpentine direction on the single-strand wire clamp 2-3, and finally clamp the grounding terminal 1-1 on the terminal clamp 2-4.

[0037] The front and back sides of the bag body 2 are both fleece-faced, and when rolled up, it can be rolled up from either side of the device, and the Velcro hooks on the front and back sides can be attached to any position of the Velcro fleece. The storage bag can also be placed in a rigid bucket for easy carrying and movement.
