The present invention discloses a pedestal used for a novel high-voltage disconnecting switch. The pedestal comprises a top plate, the installing threaded rods are all fixedly connected at the four corners of the top of the top plate, and the fixing supporting legs are all fixedly connected at the four corners of the bottom of the top plate. The sliding rods are all fixedly connected at the bottoms at the left and right sides of the fixing supporting legs, the sides of the sliding rods far away from the fixing supporting legs are fixedly connected with the fixing baffles, the moving blocks areconnected on the surfaces of the sliding rods slidably, and the first springs are in cup joint on the surfaces of the sliding rods and between the fixing baffles and the moving blocks. According to the present invention, by arranging the sliding rods, the fixing baffles, the moving blocks, the first springs, a connecting slat, a supporting rod, a supporting plate, a connecting block, a sliding rail, a limiting baffle, a sliding block, an elastic belt, a moving rod, an installing plate, a second spring, a limiting spring and a fixing pile, the anti-interference capability of the pedestal usedfor the novel high-voltage disconnecting switch is provided, the separation of the disconnecting switch from an overhauling point is avoided, a maintenance accident is avoided, and the circuit maintenance work is conducive.
Description
technical field [0001] The invention relates to the technical field of high-voltage electrical appliances, in particular to a novel base for a high-voltage isolating switch. Background technique [0002] The isolating switch is a switching device mainly used for isolating power supply, switching operation, connecting and cutting off small current circuits, and has no arc extinguishing function. When the isolating switch is in the sub-position, there is an insulation distance between the contacts and Obvious disconnection sign, when in the closing position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. The disconnector can be divided into outdoor disconnector and indoor high voltage isolation switch. Switch, outdoor isolating switch refers to the isolating switch that can withstand the effects of wind, rain, snow, pollution, condensation, ice and thick frost, and is suitable ...
