Embodiment Construction

[0024] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0025] Such as figure 1 Schematic diagram of the application of the isolating switch with decoupling in the GW7 type isolating switch, the isolating switch includes the isolating switch body 7, the output shaft 2, the decoupling device 8, and the operating mechanism box 1.

[0026] Such as Figure 2 to Figure 6 The isolating switch with decoupling function is shown, the isolating switch includes an operating mechanism box 1 and an operating mechanism, and the operating mechanism is arranged in the operating mechanism box; the output end of the operating mechanism is connected to There is an output shaft 2 and the output shaft 2 vertically protrudes from the top of the operating mechanism box 1;

[0027] The slot support plate 3 has an L-shaped structure, and the slot supp...

Abstract

The invention relates to an isolating switch with the decoupling function. The isolating switch is characterized in that the isolating switch comprises a clamping groove supporting plate, an operatingbox clamping plate, an operating handle mounting hoop and an operating handle. The isolating switch is suitable for independently overhauling the working condition of an isolating switch electric mechanism; when a mechanism is disconnected from a vertical rod, a decoupling device of the isolating switch can lock the vertical rod, and thereby the isolating switch is effectively prevented from breaking away from the switching-on or switching-off position under the reasonable impact action of gravity, wind pressure and vibration or under the condition that an operating system connecting rod is accidentally impacted in the process of debugging an electric mechanism, the position reliability of the isolating switch is improved, and further the stability of a power system is improved. The decoupling device is advantaged in that the decoupling device is simple in structure and convenient to operate, the decoupling device is suitable for common isolating switches with output shaft rotation angles of 90 degrees, 135 degrees and 180 degrees, the decoupling device is designed in a modular mode, space and cost can be saved, and a reliability problem can be solved.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to an isolating switch with a decoupling function. Background technique [0002] For the sake of safety, during maintenance, the high-voltage isolating switch or grounding switch should be temporarily locked in the closing or opening position mechanically, and the isolating switch can be reliably maintained without disengaging the mechanism from the vertical link during maintenance. In the closing or opening position, when maintaining the testing mechanism, in order to test the opening and closing performance of the mechanism separately, the mechanism will be disengaged from the vertical connecting rod. Under the action of impact, there is a risk of leaving the closed or open position. [0003] At present, among the high-voltage isolating switches on the market, some of the isolating switch bodies are designed with a structure of "over dead point" in the closing position...
