Cut-off device for separating or connecting two parts of an electric circuit, including a voltage transformer

分离或连接包括电压变换器的电路的两部分的断路器装置

Abstract

公开了一种用于分离或连接电路的两个部分(2,3)的断路器装置,所述电路包括具有绕组(32)的电压变换器(2),所述断路器装置适于呈现打开位置或闭合位置。它包括:一对电触头(123,121),包括移动触头(123)和固定触头(121),所述固定触头弹性安装以与变换器的连接元件(33)形成接触;伸缩式引导装置(10),引导装置具有固定部分(122)和可移动滑动部分(125),所述固定部分(122)相对于所述固定电触头(121)固定,所述可移动滑动部分承载移动电触头(123);以及控制装置(100),所述控制装置用于在断路器装置处于其闭合位置时使伸缩式引导装置(10)保持伸展状态,或在断路器装置处于其打开位置时使伸缩式引导装置保持缩回状态。所述成对的电触头(121,123)、伸缩式引导装置(10)和控制装置一起构成独立的子组件,以借助于固定装置(6)机械地装配到变换器。该断路器装置适用于变电站。
The device for cutting is used to separate or connect two portions (2, 3) of an electrical circuit, which comprises a transformer with a winding (32), and the device for cutting is adapted to take an open position or a closed position. The device comprises at least a pair of electrical contacts (123, 121) with a movable contact (123) and a fixed contact (121), the transformer via an element of connection (33) is contacted with the fixed contact by an elastic installation; a telescopic guiding device (10) having a fixed portion (122) and a sliding movable portion (125), and the fixed portion (122) is fixed relative to the fixed contact (121), and the movable portion supports the movable contact (123); a control device (100) for maintaining the telescopic guiding device (10) in extension when the cutting device is in a closed position, or the for maintaining the telescopic guiding device in retraction when the cutting device is in an open position. The pair of electrical contacts (121, 123), the telescopic guiding device (10) and the control device form an independent sub-component, for being assembled onto the transformer mechanically by means of the fixed device (6).
