Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present invention clearer, the device for detecting the opening and closing state of the knife switch of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] see Figure 1 to Figure 3 , the present invention provides a switch state detection device 100 . The switch opening and closing state detection device 100 is used to detect the opening and closing state of the knife switch body in the knife switch equipment. It can be understood that the knife switch device here refers to GIS (GAS INSULATED SWITCHGEAR, gas insulated fully enclosed combined electrical appliance). The GIS knife gate is an existing structure, and details will not be repeated here. ...

Abstract

The invention provides a detection device for the opening and closing state of a knife switch, which includes: an installation housing; a touch component that can be in contact with the knife switch body; a sensing component that can be movably and flexibly connected to the touch component, and can The component moves to the sensing position or resets to the initial position; when the touch component drives the sensing component to move to the sensing position, the sensing component remains at the sensing position, and the touch component can be moved relative to the sensing component continue to move to a predetermined position; and a detection component is arranged in the installation housing and can detect the sensing component at the sensing position to determine the state of the knife switch body. Due to the flexible connection between the sensing component and the touch component, the touch component can continue to move relative to the sensing component, so that the sensing component can still correspond to the detection component, and the state of the knife switch body will not change, so that accurate detection of the state of the knife switch body can be realized.

Description

technical field [0001] The invention relates to the technical field of substation auxiliary devices, in particular to a detection device for the opening and closing state of a knife switch. Background technique [0002] In power production and use, GIS (GAS insulated SWITCHGEAR, gas-insulated metal-enclosed switchgear) type switch is a common device. The opening and closing control of the GIS knife switch is generally carried out by the knife switch control box. During work, the knife switch control box starts the motor in the knife switch control box after receiving the remote electrical signal, and drives the switch input rod of the GIS knife switch to rotate after passing through the transmission system, so as to operate the GIS knife switch to complete the opening or closing action. After the knife switch control box is operated, it immediately feeds back the electrical signal of the position of its operating mechanism, that is, the primary feedback signal of the openin...
