Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0028] The invention provides a small current isolating switch. Compared with the existing PT isolating switch and its operating mechanism, the cost can be greatly reduced, the structure is compact, the operating force is small, no additional operating mechanism is needed, and the realization method is simple. Embodiments of the present invention will be further described below in conjunction with the accompanying drawing...

Abstract

An isolating switch comprises a static end assembly, a movable end assembly, a connecting rod assembly and a driving assembly thereof. The movable end assembly comprises an isolation knife, and the driving assembly drives the connecting rod assembly to move so as to drive the isolation knife to rotate, thereby achieving the switching-on and switching-off of the isolation switch. Compared with an existing PT disconnecting switch and an operating mechanism thereof, the PT disconnecting switch has the advantages that the cost can be greatly reduced, the structure is compact, the operating force is small, an additional operating mechanism is not needed, and the implementation mode is simple.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to an isolating switch. Background technique [0002] The existing PT isolating switches are all in the form of traditional knife gates. Both the static knife and the moving knife are processed by copper bars, which are large in size, high in cost, and have a large operating force. And its closing and splitting drives are all realized by a special operating mechanism, and the operating mechanism has many parts, complex design, high cost, and takes up a lot of space. Contents of the invention [0003] The purpose of the present invention is to provide an isolating switch to solve the problems in the prior art that the PT isolating switch is large in size, high in cost and additionally equipped with an operating mechanism. [0004] The invention provides an isolating switch, which includes a static end assembly, a moving end assembly, a connecting rod assembly and a d...
