Description
Technical field
This practicality relates to power transmission and distribution switchgear technical field, is specifically related to a kind of isolating switch.
Background technology
GN30 series indoor high-voltage rotary separation switch, be useful in the usefulness of doing to divide, close circuit under the non-loaded situation and isolating ground connection as voltage is arranged in the network of rated voltage 12kV, three-phase alternating current 50Hz, it is one of main devices that is used in the box fixing metal sealing switch equipment of XGN2-12.Rotary indoor high-voltage isolating switch is a kind of novel isolating switch that rotates the contact knife formula, and primary structure is to be total on upper and lower two planes at the end at three-phase, fixes two groups of insulators and contact, by the rotation contact knife, thus the divide-shut brake of realization switch.Its current-carrying part mainly is made up of contact knife and contact, and rotation contact knife copper coin parallel by two and that leave the gap is formed, and the root outside of two copper coins is respectively equipped with spring, is provided with screw rod and passes spring and copper coin, and spring is pressed on outside the root of two copper coins.Copper coin passes sleeve pipe and is fixed on the sleeve pipe, and porcelain bushing is fixed in the rotating shaft.The rotating shaft two ends during work, drive sleeve pipe by the rotating shaft rotation and make arcuate movement in spindle nose is shelved on the axis hole of framework both sides frame, cause to expose at the movable touch knife at sleeve pipe two ends to realize moving with combined floodgate or the separating brake of fixed contact.The weak point that this rotary separation switch exists in actual applications is: its minute sum velocity be to decide by the manpower size, its operating physical force is big, it is unreliable to move, instability, shaking phenomenon can appear in its contact.In addition, the root of the two copper coins outside is respectively equipped with spring, because spring body length is long, when design, owing to will consider its insulation distance, the distance between the sleeve pipe is big, makes the overall structure of product big, and volume is big, and structure is not compact, is unfavorable for the miniaturization of product.
The utility model content
Of the present utility model in order to solve above-mentioned the deficiencies in the prior art, a kind of rotary indoor high-voltage isolating switch is provided, its first purpose is to realize the function of quick divide-shut brake, promotes processing safety, reduces labor intensity of operating personnel; Its second purpose is the distance that can reduce between the sleeve pipe, and the overall structure that reduces product is big, guarantees the miniaturization production of product.
A kind of rotary indoor high-voltage isolating switch of the utility model, comprise sleeve pipe, insulator, framework, movable touch knife, fixed contact and be installed in rotating shaft on the framework, rotating shaft is in the spindle nose at both ends is installed in the axis hole of frame of framework, it is characterized in that being provided with the spring mounting panel on the frame top of framework, be connected with connecting lever on the spindle nose of rotating shaft, be connected with spring strut on the connecting lever, be provided with spring between spring strut and the spring mounting panel.
Install the divide-shut brake spring additional at the isolating switch framework, by the operating grip isolating switch rotating shaft that turns clockwise, after spring is crossed mid point, rapidly isolating switch is got to the separating brake position by spring pressure; When sub-gate position, be rotated counterclockwise the isolating switch rotating shaft by operating grip, after spring is crossed mid point, rapidly isolating switch is got to closing position by spring pressure.When isolating switch closed branch and puts in place, because the pressure of spring, its contact did not have and rocks.Its minute, sum velocity was fast, and operating personnel are laborsaving, reliable in action, stable.
During concrete enforcement, movable touch knife comprises two parallel busbars, and the root outside of two busbars is respectively equipped with the dish spring, is provided with screw rod and passes dish spring and busbar, and the dish spring is pressed on the root outside of two busbars.
The dish spring is disk spring, and it is shaped as circular cone dish shape, and is different with conventional springs, and its special effect is arranged on the function, and main feature is, load is big, and stroke is short, and requisite space is little, is used in combination conveniently, and maintenance changes the outfit easily, the economic security height.The utility model changes to the dish spring to the spring on the prior art constructions, and its size reduces greatly, and like this, the distance between each sleeve pipe of design can reduce, and makes the structure of product compacter, is conducive to the miniaturization production of product.
The beneficial effects of the utility model are: the utility model improves prior art, realizes the function of quick divide-shut brake, promotes processing safety, reduces labor intensity of operating personnel, and structure is compacter simultaneously, and volume is littler, better effects if.
