Definitions
- the invention relates to a method for producing a gas-insulated transmission line.
- Gas-insulated electrical transmission lines are known from the prior art. They comprise an inner conductor which extends inside an outer jacket tube. As an insulating medium between the internal conductor located at high voltage during operation of the transmission line and the ground potential, a suitable gas mixture is used. To avoid or minimize disturbing influences that may be caused by foreign particles inside the jacket tube, a particle trap is usually incorporated in the transmission line. Such foreign particles can enter at ⁇ play, during the manufacturing process in the transmission line. With the help of the particle trap, the foreign particles are caught, for example, in a region of low electric field strength within the transmission line, so that a trouble-free operation of the transmission line is made possible.
- the known transmission line is usually made up of tube segments during manufacture.
- the tube segments form the casing tube in a composite manner. They usually have a length between 1 m and 20 m.
- the assembly of the Rohrsegmen- te carried out for example at the place of installation or the latest, ⁇ direct operation of the transmission line, preferably in a depression for dug in the ground or in a tunnel. Mounting the particulate trap in the power tube is generally a costly process.
- the object of the invention is to specify a method for producing a gas-insulated transmission line which is as cost-effective and reliable as possible.
- the object is achieved in a method according to the invention for producing a gas-insulated transmission line in that a particle trap is displaced into an outer jacket tube along its longitudinal axis and fixed at a predetermined position with respect to the jacket tube and a movable welding robot is displaced along the longitudinal axis of the particle trap and connects the particle trap at predetermined welds with the jacket tube by welding.
- the particle trap is first introduced into the jacket tube, accurately positioned and fixed.
- the particle trap is with ⁇ means of the welding robot, which can move in the tubular casing, connected at points or with longitudinal seam with the jacket tube.
- the welding robot has suitable means to carry out the welding process.
- Welding robot is moved in the casing by being moved by means of an external drive or be moved ⁇ automatically.
- the welding robot is designed to be mobile and has suitable means of transportation such as wheels and / or der- same.
- the particle trap is expediently arranged below the inner conductor in the jacket tube. It is expediently fixed at the bottom of the jacket tube.
- the particle trap is welded selectively or over a short distance with a longitudinal seam with the jacket tube. A distance between see two welds can be 500 mm to 1500 mm.
- An advantage of the method according to the invention is that the particle trap can be flexibly connected to the jacket tube both at the location of the laying of the transmission line and in the manufacturer of the jacket tube. As a result, The cost of manufacturing the entire transmission line can be reduced.
- the attachment of the particle trap in the casing can be carried out largely automated. In this way, the time required and thus the cost of production can also be reduced. At the same time, the reliability of the manufacturing process can be increased by automating the manufacturing process, because errors caused by humans, for example when connecting the particle trap to the jacket tube, can be largely avoided.
- the particle trap preferably has a guide groove along the longitudinal axis, and the welding robot is displaced along the guide groove.
- the guide groove is suitably a recess or recess accessible to a welding head of the welding robot and extending along the particle trap.
- the guide advantageously facilitates the movement of the welding robot.
- the welding robot has its own drive and moves according to a previously defined programming specification in the jacket tube. Accordingly, the movement of the welding robot is controlled by the Program ⁇ minimizing handicap.
- the drive of the welding robot can be, for example, an electric drive.
- the energy for the drive can be provided by means of its own battery supply or via a cable by an external supply.
- the welding robot can be moved by means of an external drive.
- the welding robot can play for examples with a central station, for example by means ei ⁇ nes extendable arm be connected.
- the particle trap is preferably connected to the jacket tube by means of friction stir welding. This process is particularly simple and clean, so that foreign particles can be avoided.
- friction stir welding a welding head of the
- the welding robot has supporting means, which are set up for supporting the welding robot during the welding process.
- the welding robot on supporting arms which are extendable and support the welding robot during welding to an inner wall of the jacket tube.
- the support means give the welding robot the required stability during the welding process.
- the particle trap is not processed with short segments, but over the entire length of a pipe segment in one step.
- the particle trap is therefore introduced over its entire length of between 0.2 m and 15 m, preferably between 5 m and 10 m in the jacket tube, wherein the length of Mantelroh ⁇ res is greater than the length of the particle trap.
- the particle trap is before the welding means of a fixing joint on both sides of the jacket tube fi xed ⁇ .
- the fixing device may comprise a first fixing element and a second fixing element.
- the first Fixierele ⁇ ment will be reasonable arranged at a first end of the casing tube and the two ⁇ te fixing member at a second end of the jacket tube, so that the particulate trap can be fixed on both sides.
- the fixing device may comprise a groove which is an extension of the guide groove of the fixed particle trap forms.
- the fixing device for example both Fi ⁇ xierimplantation, may comprise a movable pedestal, by means of which the fixing device can be moved to the location of laying the transmission line. In the case of particle drops with a length between 0.2 m and 2 m, the welding robot can perform the positioning and fixing with a weld in the center.
- the jacket tube is preferably filled with an insulating gas.
- the insulating gas is suitably a gas mixture.
- the gas mixture may comprise the gas SF6, but preferably the gas mixture is SF6-free.
- the invention further relates to a gas-insulated transmission line with a jacket tube for receiving an inner conductor and at least one particle trap in the jacket tube.
- Such a transmission line is known, for example, from US Pat. No. 3,515,939 A.
- the known transmission line comprises a particle trap which is arranged in the gas-insulated line, that an area of weak field strength part as ⁇ is limited. In this area, the electric field strength is weaker by several orders of magnitude compared to the electric field strength outside the range, so that the foreign particles acting on them are
- the object of the invention is to propose such a transmission ⁇ line, which is as inexpensive to manufacture and reliable in operation.
- the object is achieved according to the invention in an art ⁇ over transmission line by the fact that the particle trap has a length between 0.2 m and 15 m, preferably between 5 m and 10 m, and with the jacket tube by puntipulem
- the length of the particle trap of at least 20 cm reduces the manufacturing costs of the particle trap.
- a further increase in the length of the particle trap permits a further Sen ⁇ effect of the cost of manufacturing the transmission line because it can be mounted in the casing ⁇ pipe in a manufacturing step, a prolonged portion of the particle trap, where it is reduced ⁇ by the logistical costs.
- the selective welding of the particle trap reduces the risk of BeCdi ⁇ supply of the jacket pipe and the particle trap. The same applies to the connection by means of the short weld.
- the particle trap has along its longitudinal axis a guide groove for guiding a welding robot.
- the guide facilitates the automation of the manufacturing process of the transmission ⁇ line. At this cost, the manufacturing cost of the transmission line can be advantageously reduced.
