[0090] The first embodiment is a preferred example of the basic embodiment. In the first embodiment, the working principle is: under the excitation of the electromagnetic excitation mechanism, the magnetic force acts on the permanent magnet or ferromagnet formed by the magnetic pole arrangement and the desired movement direction which are easier to realize the movement effect through the yoke and the ferromagnet, The moving magnet is driven to translate along the up and down direction of the paper, thereby driving the moving conductor to translate together. Such as figure 2 As shown, the moving conductor contacts the first electrode, so that an electrical connection is formed between the first electrode, the moving conductor and the second electrode. Such as image 3 As shown, the moving conductor is separated from the first electrode, so that the electrical connection between the first electrode and the second electrode is broken. During the translation process of the mov...

[0092] The second embodiment is a preferred example of the basic embodiment and also a variation example of the first embodiment. In the second embodiment, the working principle is: the moving magnet translates along the left and right directions of the paper. The dotted line therein represents the deformation state of the conductive elastic body when the moving conductor is in contact with the first electrode. Wherein, the number of moving magnets made of permanent magnets is two, and these two moving magnets are arranged and connected on the same moving conductor in a manner that their magnetic axes are in the same direction and parallel (preferably coincident), and these two moving magnets are located at Both sides of the magnetic axis of the electromagnet in the coil of the electromagnetic excitation mechanism, and. When the electromagnetic excitation mechanism is not activated, due to the supporting effect of the conductive elastic body, the movable conductor is separate...

[0094] The third embodiment is a preferred example of the basic embodiment, and is also a variation example of the first embodiment or the second embodiment. In the third embodiment, the working principle is: the moving magnet translates along the left and right directions of the paper. The dotted line therein represents the deformation state of the conductive elastic body when the moving conductor is in contact with the first electrode. A rolling guide part is arranged between the moving magnet and the cavity wall of the vacuum chamber below the moving magnet, so that the required magnetic force for driving the moving magnet is reduced, thereby facilitating fast driving. Wherein, the rolling guide component may be a ball or a slide rail, so as to achieve the effect of reducing movement resistance. Wherein, since the two electromagnetic excitation coils in the electromagnetic excitation mechanism are respectively located on both sides of the moving magnet, the moving magnet c...

Abstract

The invention provides a contact state switching device and method with a fast response. The contact state switching device comprises to-be-connected electrodes, a moving electric conductor, a moving magnet, a vacuum chamber and an electromagnetic excitation mechanism, wherein the electromagnetic excitation can excite the moving magnet; and the moving electric conductor can be in individual contact with different to-be-connected electrodes to form electric connection respectively or can be electrically connected or disconnected with at least one pair of to-be-connected electrodes under the drive of the moving magnet. The contact state switching device and method can be applied to a (vacuum) circuit switch or circuit breaker switch with the fast response. Electromagnetic links all are located at a single side or symmetrical two sides of the outside of the vacuum chamber, so that the quantity of to-be-accommodated components in the vacuum chamber is reduced; the volume of the vacuum chamber can be reduced; and a vacuum environment can be relatively easily formed.

Description

technical field [0001] The invention relates to the technical field of contact control in a vacuum environment, in particular to a fast-response contact state switching device and a high-purity vacuum realization method. Background technique [0002] Vacuum circuit breakers have the advantages of small size, light weight, suitable for frequent operations, and no maintenance for arc extinguishing, and are widely used in distribution networks. Vacuum circuit breaker is an indoor power distribution device in 3-10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations, especially suitable for oil-free, less In places where maintenance and frequent operations are used, circuit breakers can be configured in central cabinets, double-layer cabinets, and fixed cabinets to control and protect high-voltage electrical equipment. The working principle of the vacuum circuit br...
