Problems solved by technology

[0004] In order to overcome the deficiencies of the background technology, the present invention provides a disconnector with a contact indication function, which mainly solves the problem that the current disconnector has no contact opening and closing indication when the switch is opened or closed, and only uses a transparent cover for contact visualization. The transparent cover is easily blackened by the arc when the product is disconnected, making it impossible to clearly view the status of the contacts

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, the isolating switch with contact indication function includes a housing 1, an operating handle 2 is provided on the housing 1, and a The moving contact 3 linked by the operating handle 2, the housing 1 is provided with a through hole 11, the through hole 11 is equipped with an indicator 4, and the indicator 4 corresponds to the moving contact 3 Setting, the indicator 4 includes a first position where the movable contact 3 is pushed down higher than the surface of the housing 1 when the switch is opened and a second position where the drop is not higher than the surface of the housing 1 when the switch is closed . There is a through hole on the housing, and there is an indicator in the through hole. As shown in the figure, when the moving contact rises, the indicator is pressed against the indicator, and the indicator rises to the surface of the h...

Abstract

The invention relates to an isolation switch having a contact indication function, which mainly solves the problems that a transparent cover is easy to be blackened by an arc during product disconnection and the status of a contact cannot be clearly viewed due to no contact connection / disconnection indication during switching on or switching off of a conventional isolation switch and the transparent cover is only adopted as a visual contact. In the isolation switch having the contact indication function, provided by the invention, an indication element is arranged on a shell and is movably matched, the indication element exceeds the surface of the shell under the ejection of a movable contact during switching off and drops below the surface of the shell during switching on, the status of the contact can be clearly displayed, and the isolation switch is more convenient to use.

Description

technical field [0001] The invention relates to the field of isolating switches, in particular to an isolating switch with a contact indication function. Background technique [0002] When electrical equipment is being maintained, it is necessary to cut off the power supply, separate the maintenance part from the live part, and maintain an effective isolation distance. The knife switch is a switching device used as an isolated power supply. The knife switch that isolates the power supply is also called an isolation switch. The isolation knife switch is generally a no-load on-off device, which can only connect or break "negligible current" (referring to the bus bar with voltage, the capacitive current of the short cable or the current of the voltage transformer). [0003] The current isolating switch has no contact opening and closing indication when opening or closing, and only uses a transparent cover to visualize the contacts. However, the transparent cover is easily bla...
