Auxiliary mounting device for sulfur hexafluoride switch in electrical cabinet

Abstract

The invention relates to an auxiliary mounting device for a sulfur hexafluoride switch in an electrical cabinet. The auxiliary mounting device comprises a device body, a moving block is arranged at the upper part of the device body, a hydraulic cylinder placing groove is arranged in the middle of the device body, and a penetrating screw rod is arranged in the middle of the moving block; the two ends of the screw rod are rotationally fixed to the moving block through bearings, a nut is arranged on the screw rod, and a supporting column is connected with the upper end of the nut; a fixing ring is hinged to the upper part of the supporting column through a rotary locking button, clamping parts are arranged at the two ends of the fixing ring, and a hand drill motor is fixed to the position, behind the baffle, of the fixing ring; the hand drill motor is connected with the control switch through a wire, the control switch is connected with a lithium battery through a wire, and a hydraulic cylinder is arranged in the hydraulic cylinder placing groove; and the power end of the hydraulic cylinder is fixedly connected with the bottom of the moving block, a supporting screw is horizontally and fixedly arranged at the upper end of the device body, a supporting nut is rotationally arranged outside the supporting screw, and a supporting disc is arranged at one end outside the supporting nut.The auxiliary mounting device has the advantages of being convenient to use, good in auxiliary mounting effect and reasonable in structure.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an auxiliary installation device for a sulfur hexafluoride switch in an electrical cabinet. Background technique [0002] As an inert gas, sulfur hexafluoride is widely used in the power industry. At present, sulfur hexafluoride gas is mainly used in high and medium voltage power equipment. The discharge in the equipment will cause the decomposition of sulfur hexafluoride gas, and its decomposition products are the same as Structural materials are incompatible and play the role of insulation or arc extinguishing. Sulfur hexafluoride gas is placed in the SF6 switch of the electrical cabinet and sealed, which can reduce the safety distance of the switch. Many electrical companies need to use However, due to the small space in the electrical cabinet, manual installation will not only reduce the installation efficiency, but also may damage the sulfur hexafluoride switch,...

[0002] As an inert gas, sulfur hexafluoride is widely used in the power industry. At present, sulfur hexafluoride gas is mainly used in high and medium voltage power equipment. The discharge in the equipment will cause the decomposition of sulfur hexafluoride gas, and its decomposition products are the same as Structural materials are incompatible and play the role of insulation or arc extinguishing. Sulfur hexafluoride gas is placed in the SF6 switch of the electrical cabinet and sealed, which can reduce the safety distance of the switch. Many electrical companies need to use However, due to the small space in the electrical cabinet, manual installation will not only reduce the installation efficiency, but also may damage the sulfur hexafluoride switch, causing air leakage. Sulfur hexafluoride contains certain toxicity and will cause harm to the human body; therefore, it is very necessary to provide an auxiliary installation device for sulfur hexafluoride switches in electrical cabinets that is easy to use, has a good auxiliary installation effect, and has a reasonable structure
