Abstract
The utility model relates to an indoor high-voltage isolating switch used for high-voltage power transmission. The utility model is characterized in that the root part of a main switch of the indoor high-voltage isolating switch is rotatablely connected with a contact at an output end through a shaft pin, and the middle part of a frame is longitudinally arranged on a main shaft. A position corresponding to the three-phase main switch is fixedly provided with three crank arms, every phase crank arm is connected to the middle part of the main switch through an insulated pull rod and the crank arms are rotatablely connected through the shaft pin. In addition, a three-phase grounding contact is arranged on a switch cabinet body, and the position of the three-phase grounding contact corresponds to the position of a branch switch of the main switch. The utility model has the advantages of compact structure and reasonable, simple operation and high safety and reliability.
Description
The utility model relates to a kind of indoor high-voltage isolating switch that is used for high voltage power transmission and transforming.
At present, the employed indoor high-voltage isolating switch that is used for isolation circuit breakers and bus of indoor high-voltage switch cubicle generally comprises a cover operator lock and a cover ground connection disconnecting link, when elements such as maintenance circuit breaker, the operator lock disconnects, ground connection disconnecting link closure, make element reliable grounds such as segregate circuit breaker, guarantee maintenance safety.Owing to used operator lock and ground connection disconnecting link two cover disconnecting links, make the whole isolated volume of switch bigger, take space in the switch cubicle.Simultaneously, because disconnection operator lock and closed ground connection disconnecting link needed for two steps finished, increased the difficulty of locking, and misoperation easily takes place, security reliability is low.
The purpose of this utility model provides a kind of compact conformation, reasonable, indoor high-voltage isolating switch simple to operate, safe and reliable.
The technical solution of the utility model is, this indoor high-voltage isolating switch comprises that being installed in the defeated end of a three-phase on the framework goes into and three-phase output end, each phase input is installed on the framework by an insulating sleeve by a busbar, and through the framework both sides, each phase output terminal is installed in framework one side by a contact by a post insulator, it is characterized in that, one pair of operator lock is arranged between each phase input and the output, connect by the pivot pin rotation between operator lock root and the above-mentioned contact, in described frame mid portion a main shaft is installed vertically also, fixed-site corresponding with three-phase operator lock on main shaft has three connecting levers, each phase connecting lever is connected to operator lock middle part by an insulated tension pole, described insulated tension pole rotates by pivot pin respectively with connecting lever and operator lock and connects, the actuating main shaft rotates, the branch of the lock of can realizing operating, close a floodgate.In addition, also have the three-phase grounding contact to be installed on the cabinet of switch cubicle, its position is corresponding with the separating brake position of above-mentioned operator lock, when the lock of promptly operating is in the separating brake position, is combined on the grounding contact, the element ground connection such as circuit breaker that make output and connect with output.
The utility model has the advantages that, because branch, combined floodgate and the ground connection of isolating switch are all finished by a cover operator lock, omitted the ground connection disconnecting link, not only reduced the volume of isolating switch, make its compact conformation, reasonable, and, separating brake and ground connection one finishes generation misoperation easy and simple to handle and difficult because going on foot.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, each phase input of this indoor high-voltage isolating switch is installed on the framework 3 by an insulating sleeve 2 by a busbar 1, and through framework 3 both sides, each phase output terminal is installed in framework 3 one sides by a contact 4 by a post insulator 5, it is characterized in that, one pair of operator lock 6 is arranged between each phase input and the output, connect by pivot pin 7 rotations between operator lock root and the above-mentioned contact 4, in described frame mid portion a main shaft 8 is installed vertically also, fixed-site corresponding with three-phase operator lock 6 on main shaft has three connecting levers 9, each phase connecting lever is connected to the middle part of operator lock 6 by an insulated tension pole 10, described insulated tension pole 10 rotates by pivot pin 7 respectively with connecting lever 9 and operator lock 6 and connects, the actuating main shaft rotates, the branch of the lock of can realizing operating, close a floodgate.In addition, also have three-phase grounding contact 11 to be installed on the cabinet 12 of switch cubicle, its position is corresponding with the separating brake position of above-mentioned operator lock 6, when the lock 6 of promptly operating is in the separating brake position, be combined on the grounding contact 11 the element ground connection such as circuit breaker that make output and connect with output.
