Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, and in particular to a three-dimensional drag chain type water-cooled cable. Background Technology
[0002] In the current electrical market, most cables for high-current (AC or DC) transmission are water-cooled cables. Water-cooled cables are particularly useful for AC transmission, especially for medium-frequency high-current transmission. Commonly used water-cooled cables include those without spring cores and those with spring cores. Water-cooled cables with spring cores were developed specifically for high-current, medium-frequency AC transmission. However, for high-frequency (above 1000Hz) medium-frequency current transmission, water-cooled cables with spring cores are somewhat inadequate or inefficient.
[0003] Given the severe heat generation and reduced cable cross-sectional utilization of water-cooled cables under high frequency and high current conditions, a three-dimensional drag chain water-cooled cable is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a three-dimensional drag chain water-cooled cable.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A three-dimensional drag chain water-cooled cable includes a carbon-free insulating tubing. Both ends of the carbon-free insulating tubing are fitted with water-cooling components. The water-cooling components consist of a copper cable head, a current and cable head fixing ring, a clamp, a flexible hose connector, an elbow, a threaded connector, and a reducing connector. The copper cable head is fitted inside the carbon-free insulating tubing, and the connection between the carbon-free insulating tubing and the copper cable head is externally locked and fixed by a clamp.
[0007] In the above scheme, the copper cable head and the carbon-free insulating hose are locked with clamps, which are firm and have good sealing performance. This can effectively prevent coolant leakage and the intrusion of external environment such as coolant and dust. The components of the water-cooled assembly are connected by standardized thread or pipe connections, which are convenient to install, reliable to seal, and easy to maintain and replace.
[0008] The copper cable head is connected to a reducing connector, and the reducing connector, threaded connector, elbow and flexible hose connector are connected in sequence.
[0009] The carbon-free insulating tubing is internally encased in a three-dimensional drag chain.
[0010] Preferably, the three-dimensional cable chain is provided with multiple cable threading grooves, and copper cable strands are threaded through the cable threading grooves.
[0011] In the above scheme, the copper cable strands are distributed in multiple cable troughs of the three-dimensional cable chain, which increases the heat dissipation surface area, improves the contact of internal coolant, and facilitates heat dissipation. The current and cable head fixing rings ensure that each strand of the copper cable forms a stable, low-resistance electrical connection with the copper cable head, reduces contact resistance heating points, and ensures the stability and efficiency of high current transmission.
[0012] Preferably, the copper cable strands are fixedly connected to the copper cable head via current and cable head retaining ring.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The copper cable head and carbon-free insulating hose are locked with clamps, which are firm and have good sealing performance. This can effectively prevent coolant leakage and external environment such as coolant and dust from entering. The components of the water-cooled assembly are connected by standardized thread or pipe connections, which are convenient to install, reliable to seal, and easy to maintain and replace.
[0015] 2. The copper cable strands are distributed in multiple cable trays of the three-dimensional cable chain, which increases the heat dissipation surface area, improves the contact of internal coolant, and facilitates heat dissipation. The current and cable head fixing rings ensure that each strand of the copper cable forms a stable, low-resistance electrical connection with the copper cable head, reduces contact resistance and heating points, and ensures the stability and efficiency of high current transmission.
[0016] In summary, the three-dimensional cable carrier water-cooled cable divides the originally tightly packed cable into multiple zones using a three-dimensional cable carrier, significantly reducing the skin effect caused by AC current. This increases the cross-sectional utilization of the cable and reduces heat generation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, referring to Figure 1-3 A three-dimensional drag chain water-cooled cable includes a carbon-free insulating tube 3. Both ends of the carbon-free insulating tube 3 are fitted with water-cooling components. The water-cooling components consist of a copper cable head 1, a current and cable head fixing ring 5, a clamp 6, a hose connector 7, an elbow 8, a threaded connector 9, and a reducing connector 10. The copper cable head 1 is fitted inside the carbon-free insulating tube 3, and the connection between the carbon-free insulating tube 3 and the copper cable head 1 is externally locked and fixed by the clamp 6.
[0023] The copper cable head 1 and the carbon-free insulating hose 3 are locked together with clamps 6, which ensures a firm connection and good sealing, effectively preventing coolant leakage and the intrusion of external environment such as coolant and dust. All components of the water-cooled assembly are connected by standardized threaded or pipe connections, which makes installation convenient, sealing reliable, and maintenance and replacement easy.
[0024] The end of the copper cable head 1 is connected to the reducing connector 10, and the reducing connector 10, the threaded connector 9, the elbow 8 and the flexible hose connector 7 are connected in sequence.
[0025] The carbon-free insulating tubing 3 is internally encased with a three-dimensional drag chain 4.
[0026] The three-dimensional cable chain 4 is equipped with multiple cable threading grooves, and copper cable strands 2 are threaded through the cable threading grooves.
[0027] The copper cable strands 2 are distributed in multiple cable slots of the three-dimensional cable chain 4, which increases the heat dissipation surface area, improves the contact of internal coolant, and facilitates heat dissipation. The current and cable head fixing ring 5 ensure that each strand of the copper cable strand 2 forms a stable, low-resistance electrical connection with the copper cable head 1, reduces contact resistance and heating points, and ensures the stability and efficiency of high current transmission.
[0028] The copper cable strand 2 is fixedly connected to the copper cable head 1 through the current and the cable head fixing ring 5.
[0029] The copper cable head 1 is used to connect two high-current end faces, and is tightly connected with bolts for stable and reliable connection.
[0030] Copper cable strand 2 is used for the conduction of large currents in water-cooled cables.
[0031] Carbon-free insulating tubing 3 is used to form a water flow channel, cool the cable, and provide insulation protection for the water-cooled cable.
[0032] The three-dimensional cable chain 4 is used to isolate the stranded cables so that they do not get squeezed together due to mutual attraction, and to support the insulating tubing so that it is not easily flattened and thus reduces the cross-section of the water flow.
[0033] The current and cable head retaining ring 5 is used to securely fix the cable strands to the cable head and ensure stable conductivity.
[0034] Clamp 6 is used to seal the cooling water in the insulating hose and to bear the weight of the water-cooled cable.
[0035] Hose connector 7 is used to connect the inlet and outlet cooling water of the water-cooled cable.
[0036] Elbow 8 is convenient for connecting cooling water.
[0037] Threaded connector 9 is used to connect elbow 8.
[0038] Reducer 10 is used to change the diameter of the connector.
[0039] With the copper cable strand 2 separated by the three-dimensional drag chain 4, the skin effect of AC current is largely avoided, thereby greatly increasing the utilization rate of the cable strand cross-section and reducing the heat generation of the cable itself. Consequently, when transmitting the same power current, the cable cross-section can be reduced, which means that the cost of water-cooled cable is reduced, and the amount of cooling water is reduced, which means that heat loss is reduced, conductivity is increased, and the overall electrical efficiency of the equipment is increased.
[0040] Working principle: The copper cable head 1 and the carbon-free insulating tubing 3 are locked together by clamps 6. The copper cable strands 2 are distributed in multiple cable slots of the three-dimensional cable chain 4, which increases the heat dissipation surface area, improves the contact of the internal coolant, and facilitates heat dissipation. The current and the cable head fixing ring 5 ensure that each strand of the copper cable strand 2 forms a stable and low-resistance electrical connection with the copper cable head 1, reduces contact resistance and heating points, and ensures the stability and efficiency of high current transmission.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
