Abstract

The invention relates to the technical field of isolating switches, and discloses a single-grounding high-voltage isolation switch of a power system. The single-grounding high-voltage isolation switchcomprises supporting legs, a base is fixedly connected to the upper portions of the supporting legs, and a gear rotating rod is movably sleeved with the middle of the base; a first rack is connectedto the back face of the upper portion of the gear rotating rod in an engaged manner, the front face of the gear rotating rod is in engaged connection with a second rack, and the upper portion of the middle of the first rack is fixedly connected with a first jacket. According to the single-grounding high-voltage isolation switch for the power system, the upper parts of a knife switch I and a knifeswitch II are sealed by a protective baffle, so that the phenomenon of corrosion to the knife switch I and the knife switch II can be reduced in rainy days. Meanwhile, a supporting column jacket is arranged at the lower part of a spring I, so that during use, a buffering effect can be achieved through the supporting column jacket, when the protective baffle is subjected to external pressure, the buffering effect can be achieved, and the phenomenon that the protective baffle is damaged is reduced.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a single-ground high-voltage isolating switch in a power system. Background technique [0002] High-voltage isolating switch is an important switching device in the electrical system of power plants and substations. It needs to be used in conjunction with high-voltage circuit breakers. The isolating switch is suitable for indoor devices with three-phase AC 50Hz and rated voltage of 12KV. It is used for the voltage and load of high-voltage equipment Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work, and to isolate voltage. It cannot be used to cut off, input load current and break short-circuit current. For this reason, a single-ground high-voltage disconnector for power systems has been developed, but there are certain problems in the existing single-ground high-voltage disconnectors for power systems. T...
