Abstract
The utility model relates to an outdoor high-voltage vacuum isolation load switch. The utility model is characterized in that a switch transmission joint installed on a switch body is used for the connection and the installation of an intermediate transmission shaft, and an operating mechanism which can be operated manually and electrically is connected to and installed on the other end of the transmission shaft. The utility model has the advantages that the breaking capacity of the load switch is increased, and the load switch can be frequently operated; the utility model is also provided with an obvious visual fracture and is convenient to install. In addition, the utility model can be operated electrically and manually, and the reliability and the flexibility of power supply systems are greatly raised. The utility model is especially suitable for the outdoor 10 kilowatt systems of rural power networks and city power networks and electrified power supply systems for railways.
Description
The utility model belongs to H01H electric switch class technology, particularly relates to a kind of outdoor high-voltage vacuum and isolates on-load switch.
Known 10 kilovolts of outdoor high-voltage on-load switches, most structures of air pressing type or oily medium that adopt are come arc extinguishing, exist deficiency to be, and connecting-disconnecting function is little, and the life-span is short.The on-load switch that also has in addition itself is not with and is isolated outer fracture, can not carry out electric operating, so has influenced using and developing of electric power system.
The outdoor high-voltage vacuum that the big and frequent operation of a kind of connecting-disconnecting function is provided but the purpose of this utility model is to overcome the deficiency in the known technology and has an obvious visual fracture is isolated on-load switch.
The purpose of this utility model is achieved in that
Structure of the present utility model is by the switch drive joint connection intermediate propeller shaft that is equipped with on the Switch main body, the operating mechanism that the other end connection of power transmission shaft both can manually also can be electronic in the middle of it.
The structure of the Switch main body in described the utility model is, the switch drive joint is installed in lower end at underframe, end on the underframe installs the support porcelain vase, right outlet is equipped with in its upper end, at the also hinged vacuum interrupter of upper end that supports porcelain vase, be connected and installed with the line that is flexible coupling between vacuum interrupter and the right outlet, other end connection disconnecting link fixed contact at vacuum interrupter, position on underframe, go back the fitting operation insulator on the vacuum interrupter, the hinged crank that has spring of the other end of operation insulator, hinged four connecting rods that are contained in the underframe of this crank, on the axle of this crank and four rod hinge connections, also be hinged on an end of the switch drive joint that is equipped with the underframe lower end, hinged another of the four connecting rod other ends has the crank of spring, hinged another operation insulator in the other end position of this crank on underframe, the upper end of its operation insulator also is hinged with crank, on the underframe between two operation insulators, install another and support porcelain vase, the upper end of this support porcelain vase is fixed with left outlet after the contact that has engaging lug is housed again, the contiguous block of band spring is housed in left outlet, the hinged crank in upper end of the locational operation insulator of the described underframe other end is installed on the engaging lug that supports the contact that is equipped with the porcelain vase upper end.
Advantage and the good effect that the utlity model has are: owing to adopt the vacuum structure arc extinguishing, the on-load switch connecting-disconnecting function is improved, and can frequent operation, need not more multidimensional and protect.Next is to have to isolate outer fracture, makes to the utlity model has obvious visual fracture, reaches the purpose of safe ready.In the utility model, adopt reliable motor-operating mechanism in addition, both reach can be electronic also can be manual, operation is simple and reliable, improves the reliability of electric power system and the purpose of flexibility greatly.The utility model is specially adapted to the 10 kilowatts of systems in open air and the power system of electric railway of rural power grids, city net.
The utility model has following accompanying drawing:
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The utility model can be installed on the outdoor single-stage electric pole capital.Concrete structure of the present utility model is Switch main body connection intermediate propeller shaft 18, the last out splice going splice 19 on the operating mechanism 20 of the other end connection known configurations again of intermediate propeller shaft.Manually or motor-operating mechanism, by intermediate propeller shaft Switch main body in the utility model is finished and closed, divide action, can realize that motion is concentrated and remote control control.
Switch main body in above-mentioned is concrete to be constituted and is, switch drive joint 9 is installed in the lower end of underframe 8, and Switch main body is by switch drive joint and intermediate propeller shaft 18 connections.End on underframe 8 installs and supports porcelain vase 6, it supports the porcelain vase upper end right outlet 5 is installed, also be hinged with vacuum interrupter 3 at the upper end that supports porcelain vase, to be flexible coupling line 4 two ends respectively with right outlet and vacuum interrupter connection, the other end of vacuum interrupter is installed disconnecting link fixed contact 2, position on underframe, fitting operation insulator 7 on the vacuum interrupter, the hinged crank 16 that has spring of its other end, on hinged four connecting rods 10 that are contained in the underframe of this crank, on the axle of this crank and four rod hinge connections, also be hinged on an end of the switch drive joint 9 that is equipped with the underframe lower end, hinged another of the four connecting rod other ends also has the crank 11 of spring, hinged again another operation insulator 12 in the other end position of this crank on underframe, the also hinged crank 13 in operation insulator 12 upper ends, at two operation insulators 12, install again on the underframe between 7 and support porcelain vase 17, left outlet 1 is equipped with by the contact 15 that has engaging lug in its upper end, refill the contiguous block 14 of band spring on it, the hinged crank 13 in operation insulator 12 upper ends is installed on the engaging lug of contact.
Operation principle of the present utility model is: drive intermediate propeller shaft 18 by operating mechanism 20 and rotate, come opening or closing of control switch body.9 rotations of switch drive joint drive crank 16 during combined floodgate, also make four connecting rods 10 drive cranks 11 simultaneously, and by the contiguous block 14 of operation insulator 12 drive cranks 13 pressing band springs, contiguous block and disconnecting link fixed contact 2 close earlier, close after vacuum interrupter 3 is further again.And vacuum interrupter elder generation breaking current during separating brake is opened behind the disconnecting link fixed contact, and is continued to be opened to obvious visible fracture distance.
