Description
Technical Field
The utility model belongs to the technical field of the electric power system technique and specifically relates to a butt joint frock for gas insulated metal enclosed switchgear.
Background
The gas insulated metal enclosed switchgear is composed of a breaker, a disconnecting switch, a grounding switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing line terminal and the like, all of the devices or components are enclosed in a metal grounded shell, and SF6 insulating gas with certain pressure is filled in the metal grounded shell, so the gas insulated metal enclosed switchgear is also called as an SF6 totally enclosed combined electrical appliance. The accurate and fast butt joint of each module is a key factor influencing the production efficiency of gas insulated metal enclosed switchgear manufacturers. Therefore, how to butt joint flanges and basin-type insulators with various sizes is an urgent problem to be solved by gas insulated metal-enclosed switchgear manufacturers.
The early flange butt joint tooling only consists of one positioning pin. The main function of the positioning pin is to facilitate the butt joint of the flanges and play a role in guiding. Before docking, a worker needs to mount the positioning pin on one flange of the docking interface, then align the screw hole on the flange of the other module with the positioning pin, and then the other worker forcibly pushes the module into the pin. This process requires at least 2 to 3 workers to engage. Because the butt joint between the modules can involve the insertion of an inner conductor, the installation resistance is large, when the distance between the two flanges is about 10mm, the flanges are difficult to continue to advance manually, the positioning pins are required to be removed, the screw rods are replaced, then the nuts are used, and the nuts are screwed by a spanner for final butt joint. Thus, the installation efficiency is greatly reduced, and the butt joint precision is difficult to guarantee by the butt joint of manpower.
In order to solve the technical problems, chinese patent CN206864968U issued a docking tool for gas insulated metal-enclosed switchgear, which fully utilizes the lever principle and is designed with gears on its backup plate, and can be conveniently switched at any time during the docking process, thereby improving the docking efficiency. However, such a tool still has many disadvantages in use, such as: (1) the use is inconvenient, gear shifting is frequently required in the use process, and the butt joint time is prolonged; (2) the force received by the movable pin under the action of the lever principle is not in the horizontal direction, so that the force is wasted in the butt joint process.
