Abstract
The utility model discloses an grounding interlocking mechanism for insulating a switch main shaft and a grounding shaft, and is characterized in that two interlocking turned arms (3) are respectively arranged on a switch rotation shaft (2) and a switch grounding rotation shaft (6), a mounting rack (8) is arranged between the switch rotation shaft (2) and the switch grounding rotation shaft (6) and is provided with two guide fingers (4), and driver plates (5) are arranged on the guide fingers (4). The mechanism can lead the switch main shaft and the grounding shaft to be linked, the switch main shaft (2) and the switch grounding shaft (6) can only be arranged in the simultaneous separated or half-separated and half-closed states for absolutely preventing the accidents caused by mistaken closeness of switches, and the structure is simple and compact.
Description
Technical field
The utility model relates to a kind of isolating switch, and is relevant with grounding shaft interlocking device with the isolating switch main shaft of band ground connection especially.Belong to electrician's equipment technology field.
Background technology
The isolating switch of high pressure belt ground connection is the device of getting in touch of isolating, connect, change electrified body and electric device in the electrical power distribution system under the non-loaded state of circuit, wherein the grounded part of isolating switch is when isolating switch is isolated distribution system, grounded part is connected, make whole distribution system ground connection, thereby absolute guarantee to safeguard or workman's safety during construction.Optionally be with the isolating switch of ground connection now, the main shaft of isolating switch and grounding shaft are normally operated respectively with two cover operating mechanisms.For prevent that isolating switch and earthed switch from closing by mistake, two operating mechanisms of actuating isolating switch main shaft and grounding shaft need add electric interlocking, and structure is very complicated, and effect is not very good yet.
The utility model content
The purpose of this utility model is to design a kind of structure more simply with the isolating switch main shaft and the grounding shaft reciprocal interlocking mechanism of ground connection.
The utility model is achieved in that two interlocking connecting levers is set respectively that between switch rotating shaft on the installing rack and the rotating shaft of switch ground connection two guide fingers are set, guide finger is provided with driver plate in switch rotating shaft and the rotating shaft of switch ground connection.When operating mechanism operation axis actuating connecting lever, main shaft drives the interlocking connecting lever and rotates, when switch spindle has separating brake to turn to closing position, switch spindle interlocking connecting lever and driver plate contact position have k level to turn to peak, driver plate is contacted with the k level of switch grounding shaft interlocking connecting lever, the limit switch grounding shaft rotates, and makes it can not reach closing position, prevents that the isolating switch grounding shaft from closing by mistake.When switch spindle has combined floodgate to turn to the separating brake position, switch spindle interlocking connecting lever and driver plate contact position have peak to turn to k level, driver plate has mobile space between switch grounding shaft interlocking connecting lever and switch grounding shaft interlocking connecting lever, the switch grounding shaft can turn to closing position can not rotate switch spindle.
Band earthing isolator main shaft that the utility model provides and grounding shaft link gear, simple in structure, compact, prevented that definitely switch from closing the accident that produces because of mistake and taking place.
Description of drawings
Fig. 1 is the operating mechanism structural representation of existing band earthing isolator;
Fig. 2 is the structural representation of a utility model band earthing isolator main shaft and an embodiment of ground connection rotating shaft interlocking device;
Fig. 3 is the external form and the syndeton schematic diagram of interlocking connecting lever embodiment illustrated in fig. 2 and driver plate.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Among the figure: 1, operation connecting lever 2, switch spindle 3, interlocking connecting lever 4, guide finger 5, driver plate 6, switch ground connection rotating shaft 7, operating mechanism 8, installing rack
As shown in Figure 2, two interlocking connecting levers 3 are housed respectively in switch rotating shaft 2 and switch ground connection rotating shaft 6, interlocking connecting lever 3 is the ellipticity cam structure, is provided with two guide fingers 4 on the installing rack 8 between switch rotating shaft 2 and switch ground connection rotating shaft 6, and guide finger 4 is provided with driver plate 5.Operation connecting lever 1 is contained in the switch rotating shaft 2, and operating mechanism 7 and operation connecting lever 1 usefulness pin with split pin hole are hinged.When operating mechanism 7 actuatings operation connecting lever 1,1 drive switch rotating shaft 2 of operation connecting lever and the interlocking connecting lever 3 that is contained in the switch rotating shaft 2 rotate, when switch spindle 2 has separating brake to turn to closing position, interlocking connecting lever 3 on the switch spindle 2 has k level to turn to peak with driver plate 5 contact positions, the k level of the interlocking connecting lever 3 on driver plate 5 and the switch grounding shaft 6 is contacted, limit switch grounding shaft 6 rotates, and makes it can not reach closing position, prevents that isolating switch grounding shaft 6 from closing by mistake.When switch spindle 2 turns to the separating brake position by combined floodgate, interlocking connecting lever 3 on the switch spindle 2 has peak to turn to k level with driver plate 5 contact positions, driver plate 5 has mobile space between interlocking connecting lever 3 on the switch grounding shaft 6 and the interlocking connecting lever 3 on the switch grounding shaft 6, switch grounding shaft 6 can turn to closing position, but switch spindle 2 can not be rotated.Like this, switch spindle 2 and switch grounding shaft 6 can only be in time-division or the state that closed in one minute one, prevent misoperation.
Claims (2)
1. isolating switch main shaft and grounding shaft interlocking device with a ground connection, it is characterized in that: two interlocking connecting levers (3) are housed respectively in switch rotating shaft (2) and switch ground connection rotating shaft (6), installing rack (8) is positioned between switch rotating shaft (2) and the switch ground connection rotating shaft (6) and is provided with two guide fingers (4), and guide finger (4) is provided with driver plate (5).
2. a kind of isolating switch main shaft and grounding shaft interlocking device with ground connection according to claim 1, it is characterized in that: described interlocking connecting lever (3) is the ellipticity cam structure.
