The invention discloses a mechanical interlocking device for high voltage facilities. The mechanical interlocking device comprises a box body, a lock disk and a limiting mechanism are arranged in the box body, the limiting mechanism comprises a transmission shaft with one end being vertically inserted in the box body, the end inserted in the box body of the transmission shaft is provided with a limiting gear, the limiting gear is provided with a first groove and a second groove, and one end stretching out from the box body of the transmission shaft is provided with a limiting rod; and the lock disk comprises a bottom plate, a limiting slide rail parallel to the bottom plate is arranged on the bottom plate, a first limiting opening and a second limiting opening are formed in the limiting slide rail, and a first fixed slide rail, a second fixed slide rail and a third fixed slide rail parallel to the limiting slide rail are further arranged on the bottom plate. The invention aims at providing a mechanical interlocking device for safely opening and closing the high voltage facilities so as to prevent various misoperations of the high voltage facilities caused in operation or maintenance processes and improve the safety performance of the equipment. The mechanical interlocking device disclosed by the invention realizes the safe opening and closing of the high voltage facilities by means of the mechanical interlocking of an interlocking mechanism, so that the use is simple and convenient, and the operation is safe and reliable.
Description
technical field [0001] The invention relates to the technical field of interlocking mechanisms, in particular to a mechanical interlocking device for high-voltage facilities, which is used to realize the safe opening and closing of high-voltage facilities. Background technique [0002] During the operation or maintenance of high-voltage equipment, various mistakes and errors are prone to occur. In order to ensure the safety of personnel and equipment, all high-voltage electrical equipment that may cause misoperation should be equipped with an anti-mistake device. , Prevent charged from hanging (closing) the grounding wire (grounding switch), prevent power transmission with the grounding wire, and prevent strayed into the charged interval. The current high-voltage and dangerous devices are mainly guaranteed by dangerous nameplates and various rules and regulations to prevent various mistakes and mistakes. [0003] To this end, we have designed a mechanical interlock device ...
