Abstract
An indoor high pressure isolating switch comprises a chassis, wherein three phases of input ends and three phases of output ends are installed on the chassis, wherein each phase input end is provided with a static contact with a wire connecting socket, is fixed on a post porcelain bottle, and is installed on one side of the chassis, each phase output end is provided with a dynamic contact, a slot is arranged on a dynamic contact seat and the chassis with the dynamic contact seat, a pair of contact knives are arranged between each phase input end and each phase output end, the contact knives and a hinged base are rotatablely connected through a pin shaft, a control shaft is longitudinally installed on the middle portion of the chassis, the control shaft is respectively connected with three pairs of contacts knives through an insulating connecting rod, and a sealing aluminum plate is fixedly arranged on the slot. After the sealing aluminum plate is additionally arranged on the slot, the whole chassis is located in the insulating state, after the switch is installed, spacing rooms are mutually separated leftwards and rightwards, and the protection level is improved.
Description
[technical field]
The utility model belongs to a kind of components and parts of high-tension power transmission and transformation equipment, is specifically related to a kind of indoor high-voltage isolating switch that is used for the high voltage power transmission and transforming field.
[background technology]
The structure of existing indoor high-voltage isolating switch comprises a underframe, and three-phase input end and three-phase output end have been installed on the underframe, and each phase input has the fixed contact of a band junction block, is fixed on the support insulator and is installed in underframe one side.The hinged seat of on fixed contact and terminal block, also having used bolt.Each phase output terminal has a moving contact, and moving contact and busbar are by being bolted on the sleeve pipe; One pair of contact knife is arranged between each phase input and the output, and contact knife rotates by pivot pin with hinged seat and connects; Underframe middle part also vertically is equipped with a Control Shaft, and Control Shaft links to each other with the three-phase contact knife by insulated tension pole respectively, the control switch branch, closes.
The problem that prior art exists is: after isolating switch is installed, except underframe, support insulator and sleeve pipe, directly communicate between the compartment of the left and right sides on the underframe, occur misoperation when the maintainer overhauls easily and enter charged interval, therefore do not reach requirement of shelter, if user oneself adds dividing plate in the isolating switch bottom, and is very inconvenient again, particularly between wall bushing bent plate slit, can not directly seal again with steel plate, otherwise, easily produce eddy current, make the isolating switch cisco unity malfunction.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide the novel indoor high-voltage isolating switch of a kind of structure, and this switch not only is closed state between the compartment, and can not produce eddy current problem, has satisfied the High-Voltage Electrical Appliances requirement of shelter.
Adopted following technical scheme for achieving the above object, this indoor high-voltage isolating switch comprises underframe, and three-phase input end and three-phase output end have been installed on the underframe, each phase input has the fixed contact of a band junction block, is fixed on the support insulator and is installed in underframe one side; Each phase output terminal has a moving contact, has a groove on the underframe between movable contact headstock and the movable contact headstock; One pair of contact knife is arranged between each phase input and the output, and contact knife rotates by pivot pin with hinged seat and connects; The underframe middle part vertically is equipped with a Control Shaft, and Control Shaft links to each other with Third Mate's contact knife respectively by insulated tension pole, it is characterized in that: fixedly installed aluminium sheet sealing together on the described groove.
Aforesaid a kind of indoor high-voltage isolating switch is characterized in that: the underframe between fixed contact and the moving contact is provided with the seal isolation plate.
Beneficial effect: compared with prior art, the utility model had both made this groove be in isolation by after setting up the sealing aluminium sheet on the groove between movable contact headstock and the movable contact headstock, prevented operative employee's misoperation, had reached the effect that does not produce eddy current again; After setting up the seal isolation plate on the underframe between fixed contact and the moving contact, make whole underframe all be in isolation, after switch is installed, isolate mutually about between the compartment, improved degree of protection.
Following structure accompanying drawing is further described the utility model by embodiment.
[description of drawings]
Fig. 1 is for facing structural representation.
Fig. 2 is the left view of Fig. 1.
Among the figure: Control Shaft 1, fixed contact 2, underframe bent plate 3, groove 4, iron plate 5, movable contact headstock 6, underframe 7, busbar 8, sleeve pipe 9, support insulator 10, contact knife 11, insulated tension pole 12, moving contact 13.
[embodiment]
The GN27-40.5KV isolating switch is a kind of rated voltage 40.5V that is applicable to, product in the electric power system of interchange 50Hz, the usefulness of dividing, closing circuit is being arranged under the voltage immunization with gD DNA vaccine, can be supporting with high-tension switch cabinet, adapted CS6-2 operating mechanism, the design of employing reinforced insulation can be satisfied under the II level polluted place condition and use.
Referring to Fig. 1, and in conjunction with Fig. 2.This isolating switch is the boundary with underframe 7, and lower rear has been installed sleeve pipe 9 respectively.The place ahead is with sleeve pipe 9 corresponding three movable contact headstocks 6, three fixed contacts 2 of movable contact headstock 6 tops installation installed.Insulated tension pole 12 is arranged between the dynamic and static contact, and 12 actions of Control Shaft 1 control insulated tension pole divide, close a floodgate.The channel seal that was communicated about will be original by iron plate on the underframe 7 between the dynamic and static contact is separated, the groove 4 aluminium sheet sealed separation between three movable contact headstocks 6.
