[0002] Isolating switch (commonly known as "knife switch") generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch. The working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants
[0003] In the actual operation process, due to human subjective factors, it may cause misoperation, resulting in accidents in the power system

The invention discloses an intelligent disconnecting switch, which comprises a mounting base, two binding posts and a closing and opening knife gate, wherein the mounting base is provided with an electromagnet between the two binding posts; an iron core of the electromagnet is vertically arranged upwards; an integrally connected extension part is arranged at the position, corresponding to the iron core of the electromagnet, at the bottom part of the closing and opening knife gate; a spring sleeves between the extension part and the iron core of the electromagnet; and a controller for controlling on or off of the electromagnet is arranged on the mounting base. The intelligent disconnecting switch is simple in structure; and on or off of the electromagnet is controlled through the controller, so that the closing and opening knife gate is driven to carry out closing and opening actions; a misoperation caused by artificial subjective factors is avoided; and safe operation of a power system is ensured. Furthermore, the controller can carry out a field operation without an operator by wirelessly receiving a remote control instruction, so that time and cost are saved.
Description
technical field [0001] The invention relates to the field of isolating switches, in particular to an intelligent isolating switch. Background technique [0002] Isolating switch (commonly known as "knife switch") generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch. The working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. [0003] In the actual operation process, due to human subjective factors, misoperation may be caused, resulting in accidents in the power system. Contents of the invention [0004] The object of the present invention is to provide an intelligent isolating switch in order to overcome the defects and deficiencies in the prior art. [0005] Technical scheme of the present ...
