Abstract
The utility model relates to isolating and grounding switches with gas insulation. The isolating switch and the grounding switch are arranged in a metallic housing which is connected with the ground and is filled with insulating gas; the housing which is 't'-shaped is provided with four noses, one nose is used for fixing the static contact of the isolating switch, one corresponding nose along the shaft line direction is used for installing the static contact of the grounding switch, one of the other two noses is used for fixing an operating mechanism, and the other nose is used for supporting an intermediate conductor, the inner part of which is provided with a pair of rack-and-pinion gearing. The movable contact of the isolating switch and the movable contact of the grounding switch are relatively arranged on two end portions of the rack; one operating system can drive the movable contact of the isolating switch and the movable contact of the grounding switch to make the reciprocating motion in the intermediate conductor, accordingly, not only the cost is saved, but also the interlocking connection and the latching connection of the isolating switch and the grounding switch can be conveniently realized, and simultaneously, the occupied space of the elements can be reduced, and the product appearance is beautified.
Description
(1) technical field: the utility model relates to a kind of switch of isolating that can be used in, especially the isolation of using on the gas-insulated sealing electrical equipment and the switch of ground connection with ground connection.
(2) background technology: the isolation of using on known many gas-insulated sealing electrical equipment and the switch of ground connection, form by isolating switch and earthed switch respectively, and electric operating system of each autogamy operates.Also to interlock between them, (when isolating switch closed a floodgate, earthed switch did not allow the mistakenly entering into charged loop of closing a floodgate in locking; When earthed switch closed a floodgate, isolating switch did not allow to close a floodgate and makes energized circuit ground connection), the interlock connection between they are this mechanically implements very difficulty, but also make gas-insulated sealing electrical equipment complex structure, take up room bigger.
(3) summary of the invention: the purpose of this utility model is that isolating switch and earthed switch are combined, and adopts an operating system to operate, and so just is easy to realize the interlocking of isolating switch and earthed switch.And, simplify the structure, reduced cost, dwindled element and occupy the space, make gas-insulated sealing electrical equipment good looking appearanceization.
To achieve these goals, the technical solution of the utility model is to be installed in the insulation gas filled metal shell of a ground connection isolating switch with earthed switch.Hull shape is " ten " font, and four noses are arranged, and a nose is used for fixing the fixed contact of isolating switch, is used to install the fixed contact of earthed switch to a corresponding nose along its axis and with the fixed contact of isolating switch; Two other nose, one is used for fixing operating mechanism, and one is used to support the middle conductor that a pair of rack and pinion drive is equipped with in inside.And on the moving contact of the isolating switch individual both ends that are installed in tooth bar relative, and the dynamic and static contact of isolating switch and the dynamic and static contact of earthed switch are remained on the same axis with the moving contact of earthed switch.Operating system can drive the moving contact of isolating switch and the moving contact of earthed switch moves simultaneously, has so just realized isolating switch and earthed switch interlocking and latching relation mechanically.
The beneficial effect that the utility model reached is to adopt an operating system just can realize the operation of isolating switch and earthed switch, both provided cost savings, the interlocking and the latching relation of isolating switch and earthed switch have been realized again very easily, dwindled element simultaneously and occupied the space, the product appearance of having changed attractive in appearance.

(5) embodiment:
In Fig. 1, isolating switch 2 and earthed switch 3 are installed in the insulation gas filled metal shell 1 of same ground connection.Housing 1 be shaped as " ten " font, it has four noses that are used for fixing connection, one of them nose is used for fixing the fixed contact 5 of isolating switch, is used for fixing the fixed contact 7 of earthed switch to a corresponding nose along its axis and with fixed contact 5; A pair of in addition nose, one is used for fixing 8, one middle conductor 11 that isolating switch moving contact 4 and earthed switch moving contact 6 are housed by insulator 24 fixing internals of operating system.
The motion of isolating switch moving contact 4 and earthed switch moving contact 6 is to realize by a pair of gear 9 tooth bars 10 transmission devices in the middle conductor 11.Gear 9 is installed in the middle conductor 11 by bearing 12, in tooth bar 10, is arc surface (Fig. 3 illustrates) with the band flank of tooth to corresponding one side 14, it and the inner arc surface maintenance sliding contact of middle conductor 11.Respectively there is a guide pad 20,21 at the two ends of tooth bar 10, and isolating switch moving contact 4 and earthed switch moving contact 6 are separately fixed on the guide pad 20,21 by screw 23.
The axis of the axis of gear 9 and pinion 17 is fixedlyed connected an insulating bar 15 between gear 9 and pinion 17 on same center line.
During the isolating switch separating brake, power transmission shaft 13 along C to rotation, and by gear 16,17, insulating bar 15, gear 9 tooth bars 10 drive systems, driving the moving contact 4 of isolating switch 2 and the moving contact 6 of earthed switch moves together, when the fan-shaped gear wheel 16 of power transmission shaft 13 drives turns to position shown in Figure 5, stop operating.Finish the sub-switching operation of isolating switch.At this moment, isolating switch moving contact 4 and earthed switch moving contact 6 move to position shown in Fig. 4.
In Fig. 4, when earthed switch closed a floodgate, power transmission shaft 13, and when making sector gear 16 turn to position shown in Fig. 2 dotted line, stopped operating to being rotated further along C.At this moment, the moving contact 6 of earthed switch 3 moves to position shown in Figure 6.
Otherwise when earthed switch 3 separating brakes or isolating switch 2 closed a floodgate, to backward rotation, step was the same along C for power transmission shaft 13, and direction is opposite.
