The invention relates to a high voltage load switch connected by hinged joints. The high voltage load switch comprises a bottom frame, an arc extinguishing chamber, a fuse and a control box, both the arc extinguishing chamber and the fuse are fixed onto the bottom frame through insulators, an isolating switch is arranged on the bottom frame, the inner side of the isolating switch is connected with an insulated pull rod, the insulated pull rod is connected with a spindle at the center of the bottom frame through a rocker, the spindle is connected with the arc extinguishing chamber through a spring transmission mechanism, and joints on the isolating switch and the insulated pull rod are connected by the hinged joints. By the mode, transmission parts are connected by the hinged joints, so that the problem of unbalanced stress is solved, and inharmonious control force is avoided. The service life of the high voltage load switch can be prolonged, abrasion of the high voltage load switch is decreased, and noise in action of the high voltage load switch is reduced.
Description
technical field [0001] The invention relates to the field of electromechanical manufacturing, in particular to a high-voltage load switch connected by a hinged joint. Background technique [0002] The high-voltage load switch adopts the principle of vacuum arc extinguishing, with strong start-up capability, small design volume, convenient installation and maintenance, and simple operation. When the isolating switch is opened, there is a clearly visible disconnection point. The incoming line side and the load side are arranged separately, which can fully meet the requirements of Under the condition that the collector line is not powered off, it is required to replace the fuse or overhaul the transformer and the low-voltage side. However, the frequent opening and closing of the isolating switch will increase the fatigue value of its connection and affect the fatigue strength of its connection section. Moreover, it is difficult for ordinary connection ends to achieve the...
