Description

[0001] The subject of this invention is a flexible multi-wire power supply cable with linear current reception, which ensures safe contact power supply to a mobile electrical receiver moving along a designated route, such as buses (trolleybuses), suspended and cable transport vehicles, loaders in mines, automated systems for crop handling and harvesting in agriculture, self-propelled cranes, gantry cranes, transport vehicles, etc., and is also used in field conditions and temporarily, such as in construction sites or farmland and orchards.

[0002] Commonly used contact-based wired power supply systems for vehicles (e.g., trams, railway engines, trolleybuses, subways) typically use an uninsulated overhead power line from which power is obtained using a pantograph, a tilting pantograph, or, particularly in the case of trolleybuses, a pantograph with a contact shoe. Subway systems often use what is known as a third rail for their power supply. Power supply by rigid conductors predates power supply using flexible power lines. A metal conduit, approximately 20 to 25 cm in diameter with a slit at the bottom, is one of the early forms of overhead power supply systems. Moving vehicles pull on conductors moving within the conduit, which is connected to the conduit via a flexible cable. A bipolar power supply system, typically using two parallel conduits connected to a carrying rope, is also commonly used. This system was developed by Siemens and first appeared at the International Electricity Exposition in Paris in 1881. Rigid conductors were first used in the National Railroad Network in the Baltimore Loop (USA), the downtown line of the Baltimore and Ohio Railroads, and were used briefly after electrification in 1895. Z-shaped metal profiles were used as traction cables, and the motors were equipped with special receivers (later the so-called "third rail" was introduced). Power supply from overhead lines initially had to be quite complex, as seen in Charles J. Van Depoele's system, where electricity was collected using trolleys that circled the line with their side rollers (US Patent Publication US 336453). Although these receivers were quickly superseded by newer and more efficient designs, they are the origin of one of the two American names for streetcar tracks (streetcar).

[0003] The supply of electricity to overhead lines became much simpler after the discovery of the trolley pole (used in 1888 by Frank J. Sprague on the Franklin Street tram line in Richmond) and the contact pole (e.g., the tilting pole (Bügelstromabnehmer, Werner von Siemens, c. 1890)). The pole with contacts did not have to look like a lyre; it could also be rectangular (e.g., used in the Stockholm-Ushholm line, in three-phase lines—a design with an additional frame, which until recently were also used in tram lines in Rome). The trolley pole and contact pole technologies were linked by a common idea—the contact between the pole and the drive line was achieved through the flexible design of the pole itself. However, as already mentioned, both technologies required different types of overhead lines. The invention of the pantograph, dating back to the early 20th century, showed no significant influence on the shape of the overhead line adapted to the contact pole.

[0004] Before being used on trolleybus lines, if the municipal government did not approve the use of power supply tracks for this purpose, such as in Tokyo, Cincinnati, and Havana (two-pole power supply system), bipolar power supply (two overhead lines) was used in some tram track networks. One variation includes power supply without a so-called "neutral" line, such as that used on the Tábor–Bechyně railway line in the Czech Republic. One line operates at +700V, and the other operates at -700V.

[0005] Known solutions improve the safety of overhead power supply and provide the option to use three-phase power without introducing unnecessary complexity to the power supply system configuration. For example, Chinese patent application CN1283493C uses rigid dielectric overhead conductor shielding that covers three sides of the line, with one special pole capable of using four cables to achieve three-phase power supply. German patent applications and utility models DE202014102489U1, DE202014102490U1, DE102014107468A1, DE102014107466A, and DE202016104836U1 disclose various designs of rigid power lines, including semi-enclosed channels in the form of rectangular provile pipes, one side of which is cut along the longitudinal axis of the busbar, or systems of such channels made of dielectric material or metal coated with dielectric material, with rigid busbars placed in such channels in various layouts.

[0006] All of these systems anticipate the use of uninsulated, tensile cables or rigid structures, requiring appropriate load-bearing infrastructure and, for safety reasons, implying the use of low voltages (e.g., trolleybus power systems typically use voltages such as 600V or 750V), which leads to increased losses and investment costs (large cable cross-sections). Adopting a three-phase power supply system (which significantly reduces retrofit losses and simplifies the overall vehicle installation structure) is also very difficult.

[0007] There remains a need in the field, and in field conditions and temporary use scenarios, for new flexible power cables that ensure adequate insulation for use in contact power supply systems for vehicles such as tram tracks, railway engines, trolleybuses, metro cars, and suspended and linear transport carriages.

[0008] Therefore, the object of this invention is to develop a design for a flexible multi-wire power supply cable with linear power reception and ensured insulation for contact power supply systems in various vehicles.

[0009] Therefore, the object of the present invention includes a flexible multi-wire power supply cable with linear current reception, which is provided with a flexible shield made of an elastomer having typical characteristics of an electrical insulator, preferably flexible, characterized in that the wire portion is conductive, i.e., at a circumferential portion of the cross-section, it is molded inside the flexible shield, wherein internal partition strips between them constitute the components of the flexible shield, the outer surface of which transitions to symmetrical shielding strips, the shielding strips together with the internal partition strips forming guide grooves with openings at the bottom, thereby providing space for the non-insulated portion of the conductor.

[0012] The separator is preferably separated into at least two strips along the longitudinal axis, which contact but are not fixed at the outer edge of the shielding strip along the longitudinal axis of the cable, thereby forming two pockets that insulate the conductor.

[0014] A carrier strip made of steel strip or other metal, polymer strip or a mixture thereof, or natural fiber or a mixture thereof, is preferably molded inside the flexible shield and located above the conductor.

[0015] The flexible shield is preferably formed as a strip with a top surface and a bottom surface, which smoothly transitions to the shielding strip. The outer edge of the shielding strip contacts the line parallel to the longitudinal axis of the cable without being fixed, and a longitudinal guide groove is formed between the shielding strip and the conductor to form a pocket for insulating the conductor.

[0016] The bottom surface of the flexible shield is preferably provided with non-through recesses, which are placed uniformly or non-uniformly along the longitudinal axis of the cable, wherein the distance between such recesses is preferably 5mm to 300mm.

[0017] The top surface of the flexible shield is preferably provided with non-through recesses, which are placed uniformly or non-uniformly along the longitudinal axis of the cable, wherein the distance between such recesses is preferably 5mm to 300mm.

[0019] The flexible shield preferably has a fixing strip on its top, and the width of its upper base B is equal to or greater than the width of the lower base b of the strip.

[0020] The carrier rope, made of steel or other metals, polymer fibers or mixtures thereof, or natural fibers or mixtures thereof, is preferably molded inside the fixing strip of the flexible shield.

[0021] The top of the flexible shield is preferably provided with a fixing strip, wherein an opening is provided in the strip on a surface transverse to the longitudinal axis of the cable, wherein the opening is formed as a through opening or a non-through opening.

[0022] The through opening is preferably located in the flexible shield between the top surface and the bottom surface, and the distances between them are equal or different.

[0023] The surface area of ​​the cross-section of the through opening is preferably larger on the bottom side than on the top side.

[0024] Preferably, a comb structure is provided on the top of the flexible shield along the longitudinal axis of the cable.

[0025] The fixing groove is preferably disposed on top of the flexible shield along the longitudinal axis of the cable, and the open outlet edge of its cross section is narrower than the groove edge located deeper in the flexible shield.

[0026] Using the flexible multi-wire power cable with linear power reception according to the invention enables the rapid construction of secure power supply devices for mobile power receivers, including temporary solutions such as trolleybuses, and the use of specialized pantograph trolleys allows for a fundamental simplification of motor transport company infrastructure, as well as the use of significantly higher voltages and three-phase power.
