Abstract

The invention discloses a combined isolating switch, and relates to the technical field of electrical equipment. Comprising an operating mechanism and a contact switch detachably connected with the operating mechanism. The operating mechanism comprises a first shell and a driving piece arranged in the first shell; the contact switch comprises a second shell and a linkage assembly arranged in the second shell; wherein the first shell is detachably connected with the second shell, and the driving piece is detachably connected with the linkage assembly. The structure of the isolation switch can be simplified, the dismounting form is simplified, and the dismounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a combined isolation switch. Background technique [0002] The strip disconnector is usually used in conjunction with fuses and is used in places with large rated currents. It has two functions of "load breaking" and "isolation", and can add fuses to each pole for "overload and short circuit protection". Make full use of the protection characteristic curve of the fuse to protect the equipment in the cable and line, and provide an obvious disconnection point during maintenance to ensure the personal safety of the staff, and can expand the switchgear of other intelligent systems. The strip disconnector has been widely used due to its advantages of strong breaking capacity, high reliability and small size. [0003] At present, the commonly used strip disconnectors in the market have complex structures and unreasonable structural designs, which lead to difficulties in a...
