The invention relates to a solid insulation fully closed combined electrical apparatus, comprising a main switch, an isolating switch, a bus, an isolating mechanism, a V-shaped spring mechanism and a fuse protector, the isolating mechanism is connected with the fuse protector by a conducting rod, wherein, a pressing plate is arranged on the side plate of the isolating mechanism, one end of the pressing plate is contacted with one end of a poking plate, the other end of the pressing plate is hung above the striker of the fuse protector, the other end of the poking plate is matched with one end of the descending switch of the V-shaped spring mechanism, one end of a crank arm is arranged on the driving shaft of the V-shaped spring mechanism, the other end of the crank arm is connected with one end of the connecting rod, the other end of the connecting end is connected with one end of an interlocking plate, a fixing point on the interlocking plate is fixed on the isolating mechanism, the isolating mechanism operation hole of the isolating mechanism is covered by the interlocking plate after the other end of the interlocking plate is rotated around the fixing point thereof. The solid insulation fully closed combined electrical apparatus is a solid insulation fully closed combined electrical apparatus with protective measures, mis-operation of operating personnel is avoided, thereby protecting the safety of equipment and operating personnel to the maximum extent.
Description
technical field [0001] The invention belongs to products in the field of high-tech transformation of traditional industries, and relates to a solid-insulation fully-enclosed combined electrical appliance used in high-voltage power distribution equipment. Background technique [0002] Solid-insulated fully-enclosed combined electrical equipment is a switchgear used to break and close line loads. Combined electrical appliances should meet the requirements of reliable operation and flexible work, and economic conditions must also be considered. At present, there are many defects of gas-insulated combined electrical appliances (large volume, inconvenient installation, inconvenient wiring of fuses placed horizontally, relatively large contact distance in oil-free insulation technology, and the risk of gas leakage in gas insulation). The interlocking structure of gas-insulated combined electrical appliances is complex, unstable and laborious to operate. Contents of the inventio...
