Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention three station isolation grounding switch;
Fig. 2 is the vertical view of the embodiment of GIS device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The specific embodiment of three station isolation grounding switchs of the present invention, as shown in Figure 1, three station isolation grounding switchs comprise the isolation fixed contact pedestal 1 that left and right is arranged, grounding static contact seat 6 and the moving contact 5 between isolation fixed contact pedestal 1 and grounding static contact seat 6, moving contact 5 leads slidable fit in movable contact block 3, moving contact 5 has connects position for being communicated with isolation fixed contact pedestal 1 with the isolation of movable contact block 3, ground connection for being communicated with movable contact block 3 and grounding static contact seat 6 connects position and for making movable contact block 3 and the disconnection position that all disconnects between isolation fixed contact pedestal 1 and grounding static contact seat 6, isolation fixed contact pedestal 1, the spring touch finger for contacting with moving contact 5 is respectively equipped with in grounding static contact seat 6 and movable contact block 3.Isolate fixed contact pedestal 1 and movable contact block 3, couple together respectively by dead ring 2 between movable contact block 3 and grounding static contact seat 5, the two ends, left and right of the isolation right-hand member of fixed contact pedestal 1, the left end of grounding static contact seat 6 and movable contact block 3 are respectively equipped with circumferential outward extending flanged structure, and flanged structure is arranged on dead ring 2 by bolt.The right-hand member of grounding static contact seat 6 is fixedly mounted on mounting panel 7, dead ring 2 has the hole passed for moving contact 5, moving contact 5 has threaded central through hole, is spirally connected and is coated with insulation leading screw 4 in central through hole, and the right-hand member of insulation leading screw 4 is connected with the operating mechanism 8 be positioned on the right side of mounting panel 7.Drive insulation leading screw 4 rotates by operating mechanism 8, by the transmission principle of feed screw nut, moving contact 5 is moved in left-right direction, achieves and connects position in isolation, disconnects position and ground connection and connect between position and switch.In order to prevent producing iron filings attachment during moving contact 5 back and forth movement, arranging in the downside of dead ring 2 and Lou considering groove to be worth doing.
During installation, fixed contact pedestal 1, dead ring 2, movable contact block 3, dead ring 2, grounding static contact seat 6 will be isolated and connection will be installed point-blank by bolt successively, then integral installation is on mounting panel 7, makes the electric field at the two ends of dead ring reach balanced through electric Field Calculation.Tri-station isolating switch entirety is pushed in high-tension apparatus, can by the pull-out of tri-station isolating switch entirety during maintenance, convenient and swift safety.
