Embodiment 1

[0073] In the prior art, the opening and closing indicating device and the isolating switch are set separately, but as the operating time of the opening and closing indicating device increases, the transmission mechanism between it and the operating mechanism may be broken or severely worn. The coordination between the opening and closing indicating equipment and the operating mechanism is reduced, and the opening and closing indicating equipment cannot accurately indicate the opening and closing of the isolating switch, which leads to short circuits or major safety accidents, and the safety is not high. In the isolating switch provided by the present invention, the static contact assembly is provided with an indicating cylinder, and the indicating cylinder is provided with a red ribbon and a green ribbon, and the moving conductive rod in the moving contact assembly pushes the indicating cylinder to move forward. When the outer observation window on the isolating switch housing...

specific Embodiment 2

[0095] The main difference between it and Embodiment 1 is that in Embodiment 1, a red color band and a green color band are arranged on the front and rear borders of the indicating part, and the red color band indicates closing, and the green color band indicates opening. In this embodiment, other two-color ribbons of different colors from those in Embodiment 1 are arranged on the front and back of the indicator portion.

specific Embodiment 3

[0097] The main difference between it and Embodiment 1 is that in Embodiment 1, the return pressure spring is arranged in the cavity of the indicating part of the indicating cylinder. In this implementation, an annular boss is provided on the outer peripheral surface of the front side of the indicating cylinder, and the reset compression spring is set outside the indicating cylinder. Push the rear end of the hole so that when the isolating switch is turned off, the pushing indicator cylinder moves from back to front. Since the return compression spring is set outside the indicator cylinder, the aperture of the guide hole needs to be enlarged accordingly.

Abstract

The invention relates to a static contact assembly and an isolating switch. The static contact assembly comprises: a static end conductive seat, which is used for installing the static contact assembly on a housing of the isolating switch; a static end contact finger, which is conductively mounted at the front end of the static end conductive seat; an indicating cylinder, which is assembled on the static end conductive seat in a guiding and moving manner along a front-back direction, wherein the front end of the indicating cylinder is a pushing end which is used for pushing a moving contact inserted into a static end jack to move backwards so as to correspond to the closing stroke of the isolating switch; a resetting pressure spring, which is arranged in the indicating cylinder and is used for pushing the indicating cylinder to move forwards when the moving contact retreats from the static end jack, wherein the indicating cylinder is provided with a closing indication mark and an opening indication mark; and an inner observation hole, which is used for observing the closing indication mark and the opening indication mark, wherein the closing indication mark and the opening indication mark are arranged at set positions, so only the closing indication mark can be seen through the inner observation hole when the isolating switch is closed in place.

Description

technical field [0001] The invention relates to a static contact assembly and an isolating switch. Background technique [0002] GIS equipment plays an extremely important role in the process of high-voltage electricity transportation, and the isolating switch in GIS equipment is an important part of GIS equipment. Whether the opening and closing between the moving contact and the static contact is in place determines The circuit on and off of the whole GIS equipment, as disclosed in the Chinese invention patent application with the application publication number CN111799123A in the prior art, discloses a static contact assembly and a disconnector using the static contact assembly, including a moving contact assembly and a static contact assembly. The contact assembly, the static contact assembly is provided with a static contact seat, the static contact seat is fixedly installed with the housing of the isolating switch through the pot insulator, the arc contact is installed...
