Definitions

  • the utility model relates to electrical engineering and, in particular, to three-phase load switches.
  • load breakers are designed for switching rated currents and at the same time must be resistant to through short-circuit currents.
  • a high-voltage vacuum load switch containing in each phase support insulators, a vacuum arcing chamber, a mechanism for opening its contacts, the main movable and fixed contacts, which disconnects the movable contact, and the movable contacts are interconnected, as well as a shaft with a lever system transmitting rotational movement from the drive;
  • a vacuum arcing chamber is mounted on the main fixed contact by means of an insulating stand attached by the upper end by means of a screw connection to the guide cylinder, and the lower end by the main fixed contact attached to the support insulator;
  • the fixed contacts of the arcing chamber are connected by a current lead to the main fixed contacts, RU 2247439 Cl.
  • the disadvantage of the prototype is the large distance between the enclosures of adjacent arcing chambers, which should be in this device at a voltage of 10 kV of at least 135 mm in accordance with the “Electrical Installation Rules)), Ministry of Energy of the Russian Federation, 2003, section IV, chapter 4.2. At a shorter distance, breakdown is possible. The above circumstance determines the significant dimensions of the circuit breaker in accordance with RU 2247439 Cl.
  • a significant disadvantage of the prototype is the lack of reliability due to the fact that the arcing chamber due to the insufficiently rigid cantilever during interaction of the contact roller with the main movable contact oscillates in the direction of the longitudinal axis; this causes a concentration of stresses at the point of attachment of the current lead to the fixed contact of the arcing chamber, resulting in an increase in the transition resistance between them and a significant increase in temperature at the point of attachment of the lead. As a result, the conductor can melt, and the arcing chamber will not fulfill its function.
  • the objective of this utility model is to increase the reliability of the device and reduce its size.
  • a vacuum arrester in which fixed and movable contacts with a mechanism for opening them are placed, the arrester is equipped with a shell of rigid insulating material, at the same time two symmetrical side racks are made while side racks are attached to the support insulator; shell with side struts can be made of cycloaliphatic epoxy.
  • FIG. 1 is a front view; in FIG. 2 - top view; in FIG. 3 - fragment I in FIG. 1 on an enlarged scale; in FIG. 4 is a view A in FIG. 2.
  • the high-voltage vacuum load switch contains in each of the three phases two supporting insulators 1 and 2 and a vacuum arcing chamber 3, in which the fixed 4 and movable 5 contacts with the mechanism 6 for their opening are placed; the main movable contact 7 is pivotally connected to a current lead 8 fixed to the support insulator 2, to which a voltage is supplied from the source.

  • Mobile contact 5 is provided contact roller 11.
  • the fixed contact 4 is connected by a current lead 12 to the main fixed contact 9.
  • the arcing chamber 3 is provided with a shell 13 of rigid insulating material, at the same time two symmetrical side posts 14 are made, which are attached to the supporting insulator 1.
  • Shell 13 with side posts 14 can be made, for example, from textolite, however, it is preferable to make from cycloaliphatic epoxy resin, in particular, isophorondiamine or diaminodicyclohexylmethane; these resins are not hygroscopic in contrast to the PCB, which increases the service life of the shell 13 with racks 14.
  • cycloaliphatic epoxy resin in particular, isophorondiamine or diaminodicyclohexylmethane; these resins are not hygroscopic in contrast to the PCB, which increases the service life of the shell 13 with racks 14.
  • the main movable contact 7 is driven by a shaft 15 provided with a drive 16 and connected to the contact 7 through a system of articulated levers.
  • the high-voltage switch is disconnected in the reverse sequence. Due to the fact that the arcing chamber 3 is surrounded by a shell 13 made of insulating material, the distance between the bodies of adjacent arcing chambers is reduced to 100 mm at a voltage of 10 kV without the risk of breakdown, which significantly reduces the dimensions of the circuit breaker.

Abstract

L'invention concerne le domaine de l'électrotechnique, en particulier, des interrupteurs à coupure de charge triphasés. L'interrupteur à coupure de charge s'opérant dans le vide pour haute tension comprend, dans chaque phase, un isolant de base, une chambre d'extinction d'arc sous vide dans laquelle sont placés des contacts fixes et amovibles pourvus d'un mécanisme d'ouverture. La chambre d'extinction d'arc est pourvue d'une enveloppe conçue dans un matériau isolant rigide et de deux montants latéraux symétriques solidaires à l'enveloppe et fixés à l'isolant de base. L'enveloppe aux montants latéraux peut être réalisée dans une résine époxy cycloaliphatique. Cette invention permet d'accroître sensiblement la fiabilité du dispositif et de réduire ses dimensions.
