Description

TECHNICAL FIELD

[0001] The utility model relates to the energy storage technical field, and specifically points to an insulating column with vibration isolation device. BACKGROUND

[0002] At present, in the energy storage field, the insulating column is widely used in the high voltage box and the busbar cabinet. Its role is not only to support the copper bar, the electric appliance and other key components, to ensure the order and safety of circuit layout, but also to effectively isolate the potential short circuit risk in the electrical system through its excellent insulation performance. Usually, the insulating column is provided with internal threads at both ends for installation and fixation, one end is connected to the mounting panel, and the other end is connected to the copper bar or the electric appliance.

[0003] The existing insulating column mainly has two problems: firstly, in the structure strength direction, the force transmission direction is almost all transmission, and there is no buffering mechanism, which may cause the impact force to be directly transmitted to the connected components under extreme working conditions such as short circuit or overload, increasing the risk of damage; secondly, for long-distance transportation or application in the environment such as ship where vibration is frequent, the insulating column and the copper bar supported thereby are often in a low cycle fatigue state, and long-term accumulation of micro-vibration may cause material fatigue, thereby accelerating the damage of the insulating column and the copper bar, and affecting the stable operation of the entire electrical system. SUMMARY

[0004] In order to overcome the above technical defects, the purpose of the utility model is to provide an insulating column with vibration isolation device, which solves the problem of poor shock resistance of the insulating column.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An insulating column with vibration isolation device, characterized in that it comprises:

[0007] A column body, the top of the column body is provided with a groove;

[0008] A clamping assembly is installed in the groove and clamped with the column body in the groove; the bottom of the clamping assembly is provided with a receiving groove;

[0009] A vibration isolation device is installed in the receiving groove, and the two ends of the vibration isolation device are respectively in abutment with the clamping assembly and the column body.

[0010] As a preferred solution, the outer surface of the clamping assembly is provided with a flange; the top of the column is provided with clamping blocks protruding into the groove, and the clamping slots are formed between adjacent clamping blocks; the distance between the flange and the top surface of the clamping assembly is consistent with the height of the clamping blocks. The flange is used in cooperation with the clamping slots and clamping blocks, and after the flange is pressed into the groove through the clamping slots, the clamping assembly is clamped with the column by rotating the clamping assembly until the flange is located below the clamping blocks. The clamping assembly can be clamped inside the column through the arrangement of the flange, clamping slots and clamping blocks, so as to stabilize the vibration isolation device on the top of the column and play its buffering role.

[0011] Further, the flanges are uniformly distributed on the outer surface of the clamping assembly. The uniform arrangement of the flanges can uniformly distribute the stress between the clamping assembly and the column, and enhance the structural stability of the entire assembly.

[0012] As a preferred solution, the top surface of the clamping block is flush with the top surface of the column.

[0013] As a preferred solution, the height of the clamping assembly is less than the height of the groove. After the assembly of the insulating column, the clamping assembly will be subjected to an upward thrust of the vibration isolation device, and the clamping assembly will be clamped in the groove due to the limiting action of the clamping blocks. At this time, the top surface of the clamping assembly is flush with the top surface of the clamping blocks and the column. The height of the clamping assembly is set to be less than the height of the groove, so as to leave a certain space between the bottom surface of the clamping assembly and the bottom of the column groove, thereby providing a buffering space for the vibration isolation device.

[0014] As a preferred solution, the accommodating groove is an annular groove, and a center column is arranged in the center part of the annular groove.

[0015] As a preferred solution, the vibration isolation device is a rubber pad or a spring.

[0016] Further, the vibration isolation device is a spring, and the spring is sleeved on the center column or fixedly installed around the center column. The vibration isolation device is arranged to buffer the force from the vertical direction on the insulating column, so as to reduce the influence of vibration on the quality and safety of the electrical appliance.

[0017] Further, a screw hole is arranged at the center of the top of the clamping assembly for connecting with the electrical appliance through a bolt; and a screw hole is arranged at the center of the bottom of the column for connecting with the mounting panel through a bolt. The screw holes arranged at the centers of the clamping assembly and the column can ensure that the insulating column is uniformly stressed during use, and the connection of the insulating column with the electrical appliance and the mounting panel through the screw holes of the bolts can ensure the stability of the electrical appliance. The screw hole at the center of the top end of the clamping assembly can be deep into the center column, and the center column can ensure the stability of the threaded connection of the screw hole and the bolt.

[0018] As a preferred embodiment, the insulating pillar is made of BMC material. Bulk molding compound (BMC) has excellent insulation properties, aging resistance, and mechanical properties such as tensile, flexural, and impact strength. Using it as a material for insulating pillars can effectively improve the mechanical properties and fatigue resistance of the insulating pillars.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention adds a vibration isolation device in the vertical direction of the insulating column, solving the problem of poor seismic performance and reducing vibration stress during transportation. By using the insulating column of this invention, the weight of the copper busbar can be reduced while ensuring its current carrying capacity. The insulating column material in this invention is BMC, which has high plasticity and can be shaped as needed. In summary, the insulating column of this invention has high overall vibration resistance and fatigue strength, and can be used in various specifications of high-voltage boxes, combiner cabinets, etc. Attached Figure Description
