Description

The invention relates to a high-voltage circuit breaker for one pole and its use, with interrupter units which are connected in series and are connected to one another in a mechanically stable manner. The interrupter units are arranged on at least one carrier.

A high-voltage circuit breaker, in particular for switching voltages of up to 1200 kV and/or currents of up to a few hundred amperes, is e.g. B. from the DE 196 01 053 C1 known. The outdoor high-voltage circuit breaker comprises two interrupter units for one pole, each of which is arranged in a composite insulator housing. The two interrupter units are connected in series and arranged along a common longitudinal axis together with the associated composite insulator housings. The two composite insulator housings, each with an interrupter unit, are arranged on a pole column or a support and connected to one another via a deflection gear. The high voltage outdoor circuit breaker has a T-shape with two arms, each arm including a breaker unit.

Gas-insulated interrupter units, in particular with a rated current contact and with an arcing contact as switching contacts, are used to switch high voltages and currents. The composite insulator housings, in which an interrupter unit is located, are filled with a switching and/or insulating gas, in particular SF ₆ . For good electrical insulation between switch contacts, and across open switch contacts, the pressure of the switching and/or insulating gas in the composite insulator housing is one bar or greater. The composite insulator housings are gas-tight, with good gas insulation. The gas insulation must be stable over the long term, in particular for more than 30 years. The switching gases such. B. SF ₆ , are environmentally harmful, particularly harmful to the climate and a leakage rate of less than 0.1% must be guaranteed for the composite insulator housing with interrupter unit long-term stability.

In order to avoid climate-damaging switching and/or insulating gases, vacuum tubes in particular are used as interrupter units. Vacuum tubes are designed to switch voltages up to several 10 kV. In the case of high switching capacities, in particular switching voltages well in excess of 100 kV, several vacuum tubes are connected in series. The vacuum tubes can be provided directly with a weatherproof insulation, or they can be arranged in a composite insulator housing. The number of interrupter units connected in series and arranged one behind the other, and thus the maximum power or voltage to be switched, is limited by the mechanical properties of the high-voltage circuit breaker. environmental influences such as B. wind, can lead to high mechanical stresses on the arms of a T-shaped high-voltage circuit breaker.

With an increasing number of breaker units arranged in series, the length of the arms increases and mechanical components such as e.g. B. the pole column, the deflection gear and connecting elements must be reinforced to ensure long-term high reliability and mechanical stability of the high-voltage circuit breaker. This entails high costs, increased material costs and/or shorter maintenance intervals. As the length of the arms of a T-shaped high-voltage circuit breaker increases, the mechanical stress increases sharply, particularly at the ends of the arms facing away from the pole column, and further lengthening of the arms for higher voltage levels may be impossible. With an increasing length of the arms of a T-shaped high-voltage circuit breaker, the area occupied by the High-voltage circuit breaker too, resulting in higher costs.

CH 483 106 A discloses a high voltage circuit breaker according to the preamble of claim 1.

The object of the present invention is to provide a high-voltage single-pole circuit breaker and its use which avoid the problems described above. In particular, the task is to specify a simple, compact and inexpensive high-voltage circuit breaker which is mechanically stable and environmentally friendly and has a long service life, and which can be designed for high voltage levels.

The specified object is achieved according to the invention by a high-voltage circuit breaker for one pole with the features according to patent claim 1 and/or by using the high-voltage circuit breaker according to patent claim 11 . Advantageous refinements of the high-voltage circuit breaker according to the invention for one pole and its use are specified in the dependent claims. Subjects of the main claims can be combined with one another and with features of the subclaims and features of the subclaims with one another.

A high-voltage circuit breaker for one pole according to the invention comprises interrupter units which are connected in series and are connected to one another in a mechanically stable manner. The interrupter units are arranged on at least one carrier. The interrupter units are arranged on different axes.

By arranging several interrupter units on different axes, more interrupter units can be arranged compactly in the smallest of spaces. The interrupter units can be placed closer to a point, particularly the intersection of the axes, mechanical support at that point resulting in a mechanically stable, compact, high voltage circuit breaker for high voltage levels. It more than just two interrupter units can be stably arranged, which means that when connected in series, the voltages to be switched increase compared to high-voltage circuit breakers of the prior art.

The interrupter units may comprise vacuum tubes and/or gas-filled circuit breakers, particularly with rated and arcing contacts, particularly in an outdoor switchgear. The total switching voltage of the high-voltage circuit breaker can be increased due to the higher possible number of interrupter units connected in series, in particular with interrupter units having a maximum switching voltage. Especially with vacuum tubes, which only with switching voltages of z. B. are to be manufactured in large numbers up to 35 kV, an inventive arrangement of the interrupter units can not only one axis behind the other, but on different axes z. B. equidistant from each other along a circumference, allow an increase in the total switching voltage of the high-voltage circuit breaker. In the case of gas-filled circuit breakers, in particular with rated and arcing contacts, the arrangement of the interrupter units according to the invention can enable high switching voltages of up to 1200 kV and higher.

The interrupter units can be arranged in one plane, in particular in a plane essentially parallel to the ground. This enables a compact, cost-effective construction of a high-voltage circuit breaker according to the invention, which is mechanically stable and can be designed for high voltage levels. When using vacuum tubes without environmentally harmful switching gases such. B. SF ₆ , and / or when using gas-filled or gas-insulated circuit breakers, especially with nominal and arcing contacts, z. B. using clean air for lower switching voltages of a few 100 kV in particular, a durable, environmentally friendly high-voltage circuit breaker for high voltage levels can be produced. The arrangement of Interrupter units in one plane allows good insulation from the ground with sufficient clearance, ie the ground potential and/or the floor surface on which the high-voltage circuit breaker is installed or in which the high-voltage circuit breaker is anchored in the foundation. A support frame with insulation for the high-voltage circuit breaker can be designed with a minimum height, since all interrupter units can be arranged at the minimum height or at the minimum distance from the ground for the voltage level to be switched. A risk for maintenance personnel in particular at the level of the foundation due to electrical flashovers can be avoided or reduced.

At least two interrupter units can be arranged on a common longitudinal axis. Different longitudinal axes can be included, which intersect at one point, in particular with an angle between the longitudinal axes of 90 degrees. As a result, a large number of interrupter units can be connected in series, with good electrical insulation between the interrupter units in areas which are not electrically conductive due to the wiring. In particular, with an arrangement of four interrupter units on two axes which form an angle of 90 degrees, e.g. B. arranged with a support frame with insulation in the middle at the intersection, for a mechanically stable arrangement even under adverse environmental influences such. B. in a storm, the interrupter units can be well electrically insulated from each other due to the distance in areas that are not electrically connected via the wiring. For example, the axes may form a cross and the breaker units may be equally spaced along the axes, with adjacent breaker units on different axes being spaced equal to the spacing of breaker units on a common axis.

The interrupter units can be arranged in such a way that the longitudinal axes of the interrupter units are star-shaped, in particular with a common point of intersection, and/or that the longitudinal axes of the interrupter units are arranged on a cross. At a common intersection of the axes z. B. in the shape of a star or a cross, a maximum number of interrupter units can be arranged on a circumference in a plane with, in particular, the same distance from one another. This results in a particularly compact, cost-effective construction, in particular with a support frame with insulation arranged at the common point of intersection, for high mechanical stability, with a large number of interrupter units, i. H. high possible switching voltage, and good insulation of the interrupter units from each other by the ambient air in areas that are not electrically connected.

The interrupter units can be connected in series using electrical cables and/or busbars made of copper and/or aluminum.

The electrical cables and/or busbars are arranged in at least one connection housing between interrupter units, the connection housing being arranged at free ends of the interrupter units and having no mechanically supporting function for the interrupter units. The insulation of the electrical cables and/or busbars via connection housings prevents electrical flashovers and enables a compact arrangement of the interrupter units with series connection. In particular, interrupter units and electrical cables and/or rails can be electrically insulated from the outside by insulators, which means that small spatial distances between the interrupter units and electrical cables and/or rails are possible when the voltages and/or currents to be switched are high.

The high-voltage circuit breaker according to the invention can comprise exactly one support, in particular in the form of a column and/or standing upright. The wearer can Having a post insulator or a plurality of post insulators, in particular connected via flanges, post insulators in particular comprising ceramics, silicone and/or composite materials. The carrier can include a base housing, in particular made of metal. The carrier can also include a support structure, in particular made of metal. As a result, high mechanical stability is possible with little effort or expense and with good electrical insulation of the interrupter units from the subsoil or foundation.

The interrupter units arranged on the at least one carrier can be mechanically fastened to the carrier and/or to a gear housing which is arranged on the carrier, in particular directly and/or via insulating bodies and/or connecting housings and/or housings of the interrupter units, in which the interrupter units are arranged. As a result, good mechanical stability of the high-voltage circuit breaker can be achieved with good electrical insulation of the interrupter units from one another and from the background in areas in which the interrupter units are not electrically connected in series.

A drive can be included, in particular arranged laterally on the carrier, and/or elements of a kinematic chain can be included, in particular deflection gears and/or shift rods, for transmitting a drive movement from the drive to the interrupter units for in particular simultaneous switching of the interrupter units. When switching, kinetic energy can be provided simply, inexpensively and reliably via the drive, which is transmitted via the elements of the kinematic chain to movable contact pieces of the switching contacts of the interrupter units.

Insulating devices, in particular insulators and/or post insulators, can be insulated with an insulating gas, in particular Be filled with clean air, in particular with a pressure in the range of the ambient pressure of the high-voltage circuit breaker. When using an insulating gas such. B. Clean Air, good electrical insulation can be achieved, especially without harmful environmental influences such. B. damage to the climate. When using a pressure in the range of the pressure of the ambient air, the seals are less stressed, remain tight over the long term and can be designed easily and inexpensively.

A use according to the invention of the high-voltage circuit breaker for one pole includes the use in an outdoor switching device, in particular in an outdoor switching device with three poles. This makes switching z. B. consumers, power grids and / or power generators possible at high voltage levels of z. B. up to 1200 kV and more, and in particular for three phases or with three poles.

The advantages of the use according to the invention of the high-voltage circuit breaker according to claim 11 are analogous to the previously described advantages of the high-voltage circuit breaker according to the invention for one pole according to claim 1 and vice versa.
