The switch comprises a separated static contact assembly, a mobile contact base assembly, a grounding static contact assembly; the mobile contact base assembly can be respectively cooperated with separated static contact assembly and the grounding static contact assembly via the fins which are arranged on the transmission shaft. The utility model achieves the mechanical lockage and assures the reliable and precise operation which radically solves the error operations. The utility model is not only electrically operated, but also can be operated by man power via a handle; the manufacturing cost is low and the installation and modulation is convenient.
Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances, is specifically related to a kind of three-station isolating/grounding switch that is used for High-Voltage Electrical Appliances.
Background technology
The isolating/grounding switch that is used for High-Voltage Electrical Appliances of domestic production at present mostly is two stations, promptly only establish combined floodgate, two positions of separating brake, in order to ensure personal safety, can only realize fool proof logic blocking on electric, but electrical interlock exists certain problem as artificial misoperation, electric wire virtual connection and the adhesion of secondary component contact etc.
The utility model content
The purpose of this utility model is the defective that exists at above prior art, provide a kind of simple in structure, volume is little, the realizing of reliable operation closed a floodgate, the three-station isolating/grounding switch that is used for High-Voltage Electrical Appliances of separating brake, three kinds of functions of ground connection.
Realize that the above-mentioned purpose technical scheme is:
The utility model comprises the assembling of isolation fixed contact, the assembling of movable contact headstock, the assembling of ground connection fixed contact, and the assembling of movable contact headstock can match with the assembling of isolation fixed contact, the assembling of ground connection fixed contact respectively by the blade that is contained on its power transmission shaft.
The utility model structure has realized mechanical interlocking, guarantees reliably operation accurately, has fundamentally solved misoperation.Both but electric operating also can carry out dependent manual operation by handle, and its low cost of manufacture, Installation and Debugging are conveniently.

Embodiment
As shown in Figure 1 and Figure 2, the utility model is used for the three-station isolating/grounding switch of High-Voltage Electrical Appliances, comprise isolation fixed contact assembling 1, movable contact headstock assembling 2, ground connection fixed contact assembling 3, movable contact headstock assembling 2 can match with isolation fixed contact assembling 1, ground connection fixed contact assembling 3 respectively by the blade 12 that is contained on its power transmission shaft 13.This switch is by the rotation of outer distribution pneumatic operating mechanism, drive the power transmission shaft 13 of movable contact headstock assembling 2, thereby drive blade 12 clockwise or be rotated counterclockwise respectively with isolate fixed contact assembling 1, ground connection fixed contact assembling 3 matches, and realizes branch, the function of closing a floodgate.
It is identical with the structure of ground connection fixed contact assembling 3 to isolate fixed contact assembling 1 shown in Fig. 1, sees Fig. 3, Fig. 4, comprises shielding part 4, first fingertip 5, first 6, first spring 7, pin 8, second 9, second spring 10; 28 first fingertips 5 are divided two groups equally and are placed between shielding part 4 inside grooves, and 14 every group first fingertips 5 connect together by first 6, connect together by pin 8, second spring 10 between two group of first fingertip 5.Connect together by second 9 between two shielding parts 4.
The structure of the headstock of movable contact shown in Fig. 1 assembling (2) is seen Fig. 5, Fig. 6, comprises conductor 11, blade 12, power transmission shaft 13, fingertip seat 14, the 3rd spring 15, second fingertip 16; Blade 12 is fixed between conductor 11 inside grooves by power transmission shaft 13, two fingertip seats 14, is provided with 27 second fingertips 16 and corresponding the 3rd spring 15 in the endoporus that each fingertip seat 14 upper edge circumferential edge distributes.
Operation principle of the present utility model: the divide-shut brake of (one) tri-station isolating switch: when blade 12 mediates, after motor-operating mechanism is received and is isolated the closing operation order, the motor-operating mechanism main shaft turns clockwise 270 ° and drives blades 12 by the power transmission shafts (13) that connect and turn clockwise 90 °, isolates fixed contacts assembling 1 and realizes the isolating switch closing operation thereby blade 12 inserts.Otherwise then realize the sub-switching operation of isolating switch.The divide-shut brake of (two) three station earthed switches: when blade 12 mediates, after motor-operating mechanism is received the contact of earth operational order, the rotation of motor-operating mechanism spindle axis counterclockwise drives blade 12 by the power transmission shaft 13 that connects for 270 ° and is rotated counterclockwise 90 °, is grounded the switch closing operation thereby blade 12 inserts ground connection fixed contact assembling 3.Otherwise then be grounded the sub-switching operation of switch.
