Description

Technical Field

[0001] The utility model relates to the technical field of packing cases, and particularly relates to a packing case structure for a high and towering coupling capacitor. Background Art

[0002] With the increase of power demand, the scale of the power grid in China is also continuously increasing, and the power grid construction in high altitude and high pollution areas has developed rapidly; at the same time, higher requirements are put forward for the safety and stability of power equipment in these areas.

[0003] Coupling Capacitor (abbreviated as CC): is a capacitor used to transmit signals in the power network, mainly used in power frequency high-voltage and ultra-high-voltage AC transmission lines to achieve purposes such as carrier, communication, measurement, control, protection, and extraction of electric energy. The coupling capacitor can be applied to AC and DC transmission systems, and can also be used as the high-voltage coupling part of a capacitive voltage transformer. Generally, the coupling capacitor uses the bushing as the outer shell of the capacitor. For coupling capacitors in high pollution and high altitude areas, it is necessary to increase the height and creepage distance of the bushing to improve the insulation strength of the capacitor. After the height of the product shell is increased, that is, a high and towering coupling capacitor, the height generally exceeds two meters, and the diameter is only 400 - 500 mm. At the same time, to prevent the internal core of the capacitor from loosening and the components from being displaced, resulting in changes in the electrical performance of the product, it must be vertically packaged and transported. In the prior art, a separately packaged wooden packing case is used, which includes a wooden base, a wooden box body, a cover plate, and other necessary fixing parts. The capacitor to be packaged is fixed on the wooden base through bolts, then the wooden box body is sleeved outside the capacitor, and the bottom is fixed to the wooden base by nails. Finally, the cover plate is fixed on the top of the wooden box body. To prevent the capacitor from tipping over, a cross-shaped support is arranged at the top inside the box, and the hole in the middle of the cross-shaped support is sleeved on the top cover of the capacitor; while using a separately packaged wooden packing case, when the height of the assembled capacitor is too high, the length and width dimensions of the packing case remain unchanged, and the height increases, which will cause the center of gravity of the packing case to be too high and the bottom to be unstable during storage, transportation, and handling, resulting in tipping over; similar accidents occur frequently because the bottom area of the packing case is too small and the height is too high. However, when increasing the cross-sectional area of the packing case, it will lead to an increase in the cost of the packing case and transportation cost; in addition, the wooden base of the packing case is not suitable for fixing the capacitor by bolt assembly; due to the low hardness of the wood, after the capacitor shakes frequently, the wood is compressed, the assembly bolts are loosened, and finally the capacitor topples inside the packing case. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a packaging box structure for a tall coupling capacitor to overcome the problems existing in the prior art. The present utility model can pack multiple capacitors in the same packaging box, which can increase the bottom area of the packaging box, thereby preventing the packaging box from tipping over; each component of the packaging box is processed by using profiled steel and welding, and finally assembled and fixed by bolts, which improves the durability and reliability of the packaging box; the bottom and top of the product are fixed to the packaging box by bolts, further improving the stability of the product; the packaging box structure of the present utility model is stable and can effectively improve the packaging quality of the product, especially having a significant improvement effect on the transportation environment with long distances and harsh road conditions.

[0005] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0006] A packaging box structure for a tall coupling capacitor, including a base. The base includes a plurality of longitudinal support beams arranged at the bottom, and a plurality of transverse support beams are installed on the plurality of longitudinal support beams. Outer limit angle steels are respectively arranged at both ends of the two outermost longitudinal support beams, and lifting rings are also fixed on the two outermost longitudinal support beams; a coupling capacitor is arranged on the base, a guardrail is installed outside the coupling capacitor, the bottom of the guardrail is fixed on the base, and a top pressing plate is installed at the top of the guardrail;

[0007] Further, a plurality of bottom mounting holes are arranged on the transverse support beam;

[0008] Further, the coupling capacitor is fixed on the bottom mounting holes of the transverse support beam by double nuts or lock nuts;

[0009] Further, a plurality of base connection holes are arranged on the outer limit angle steel, and a plurality of guardrail connection holes are arranged at the bottom of the guardrail;

[0010] Further, the guardrail is fixed by a connecting member that mates the guardrail connection holes with the base connection holes of the outer limit angle steel;

[0011] Further, the guardrail includes a plurality of longitudinally and transversely arranged beams that are staggered;

[0012] Further, a plurality of top mounting holes are arranged at the top of the guardrail, and a plurality of side holes are arranged on the top pressing plate;

[0013] Further, the top pressing plate is fixed by a connecting member that mates the side holes with the top mounting holes of the guardrail;

[0014] Further, a middle hole is arranged on the top pressing plate, and a reserved hole is arranged at the top of the coupling capacitor;

[0015] Further, the coupling capacitor is fixed by a connecting member that mates the reserved hole with the middle hole of the top pressing plate.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The utility model provides a packaging box structure for a high-rise coupling capacitor. A base formed by several longitudinal support beams and transverse support beams arranged at the bottom forms a stable support structure, which can effectively support and protect the internal high-rise coupling capacitor, enhance the overall stability and load-bearing capacity of the packaging box, and ensure the safety of the capacitor during transportation and storage; a lifting ring is arranged on the outermost longitudinal support beam of the base, so that the entire packaging box can be lifted and moved smoothly and safely during hoisting, greatly improving the transportation efficiency, and at the same time reducing the operation difficulty and labor cost; a guardrail is installed outside the coupling capacitor, and a top pressing plate is arranged at the top of the guardrail to form an overall protection system, which can not only effectively prevent the capacitor from shaking and colliding during transportation, but also prevent direct damage to the capacitor caused by external factors, further improving the protection effect of the capacitor; the reasonable structural design enables the packaging box to make full use of the internal space, provides sufficient installation and fixing space for the high-rise coupling capacitor, and avoids transportation risks caused by insufficient space; the packaging box structure of the utility model is generally used for multiple capacitors of the same specification. When multiple capacitors are packaged in one box, the material cost and transportation cost of the packaging box can be reduced, and the bottom area of the packaging box can be increased through multi-section packaging, avoiding the tipping of the product due to too high center of gravity.

[0018] Furthermore, by arranging bottom mounting holes on the transverse support beam and fixing the coupling capacitor on the transverse support beam, the use of double nuts or lock nuts can significantly increase the fixing force on the coupling capacitor. The lock nut can effectively prevent loosening through its special locking mechanism, while the double nut enhances the fixing effect by adding an additional nut. Both can significantly improve the stability of the capacitor during transportation and storage and prevent the bolts from loosening due to vibration during long-distance transportation.

[0019] Furthermore, by arranging base connection holes on the outer limit angle steel and arranging guardrail connection holes at the bottom of the guardrail, and then using these connection holes to firmly fix the guardrail on the base, this design significantly enhances the overall stability of the packaging box, ensuring that even when encountering bumps or vibrations during transportation, the guardrail can closely fit around the coupling capacitor to prevent it from shifting or being damaged; the firm fixation of the guardrail not only protects the coupling capacitor from external impacts and damages, but also improves the safety of the operator during loading, unloading and transportation.

[0020] Furthermore, by setting up a guardrail structure with staggered vertical and horizontal beams, the overall rigidity and stability of the guardrail can be significantly enhanced. The mesh or frame structure can effectively disperse external impact forces, preventing deformation or damage caused by excessive single-point stress.

[0021] Furthermore, through the cooperation of the top mounting holes and the side holes, the top pressing plate can be firmly and tightly fixed on the top of the guardrail, not only enhancing the structural strength of the top of the packaging box, but also ensuring the stability of the entire packaging box during transportation; the tight connection between the top pressing plate and the guardrail forms a complete protection system, which can comprehensively protect the tall coupling capacitor from external impacts and damages. Even if the packaging box encounters bumps or vibrations during transportation, the top pressing plate can effectively prevent the capacitor from being impacted.

[0022] Furthermore, in addition to fixing the coupling capacitor on the base, it is also fixed through the middle hole of the top pressing plate and the reserved hole of the coupling capacitor, realizing double fixation, significantly improving the stability of the coupling capacitor in the packaging box, and preventing it from shifting or being damaged due to vibration or impact during transportation.
