Specific embodiment
To describe technology contents of the invention, structural feature in detail, purpose and effect being realized, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, a kind of gas-insulated switch external member of the invention, including upper cover plate 5, ejection sleeve pipe 1, nut 6, conduction
Bar 8, connection busbar 7, the connection busbar 7, nut 6, conducting rod 8 are located at upper cover plate lower section；
The connection busbar 7 is connected and fixes with the switch bus of gas-insulated switch, and the connection busbar includes through hole,
The conducting rod 8 is passed through from through hole, and nut 6 is used to conducting rod 8 is pre-fixed in connection busbar 7, nut and conducting rod
Limiting section is located at respectively the upper and lower sides of connection busbar, and the connecting portion of conducting rod is upwardly extended through nut, and the elongated through hole cuts
Face is more than the section of conducting rod 8.Gas-insulated switch inside has the switch bus being powered, and in some specific embodiments, leads to
Cross connection busbar and electric power is oriented into conducting rod, ejection sleeve pipe is oriented to by conducting rod and is outwards transmitted, in our embodiment, such as
Shown in figure, conducting rod is passed through from through hole and contacted with busbar is connected, then outwards transmits electric power with ejection casing-contact.
In the embodiment shown in fig. 1, the ejection sleeve pipe 1 includes support set 4, embedded division, and the support set 4 is located at embedding
Enter portion top, the lower surface of support set 4 is with upper cover plate 5 against the embedded division is connected through the upper cover plate 5 of casing with conducting rod 8.
By above-mentioned setting, because elongated through hole section is more than conducting rod section, but the diagonal-size of conducting rod neck square-section is big
In the minor axis dimension in elongated hole section；, in the case of nut and conducting rod in advance locking, conducting rod can be remained able in horizontal plane
Be finely adjusted position, thus reached can leading joint sealing, then conducting rod position is finely adjusted from the opening of upper cover plate it is right
In, then tightening nut, assembling ejection sleeve pipe, the production technology of gas-insulated switch is improved, different from first filling in prior art
With upper cover plate, sealed ejection sleeve pipe is relatively fixed with upper cover plate, then the step of carry out joint sealing, technical scheme causes spiral shell
Mother will not be affected with the position of conducting rod due to follow-up joint sealing formality, and be solved in prior art due to accumulative mistake
Difference is present, and the problem that the non-adjustable ejection sleeve pipe for causing in conducting rod position cannot be aligned when assembling with ejection sleeve pipe.
In order to preferably produce to gas-insulated switch, at least bending downwards on one side of our upper cover plate is used as side
Right plate in plate, such as Fig. 1 and, parallel to paper, unshowned front side plate and rear side plate can be designed to one
It is overall but so higher to the difficulty and required precision of panel beating bending, in some preferred schemes, only by upper cover plate and right side
Side plate design be integrated i.e. " 7 " font, so in process of production, eliminate without the need for being cut and at least a step welding
Step, saves the energy, workman's man-hour.Only need only to do one piece of larger sheet metal, then sheet material is bent into bending equipment
Orthogonal upper cover plate and side plate.Because without first assembling upper cover plate, sealed ejection sleeve pipe is relatively fixed with upper cover plate,
Joint sealing is carried out again, and gas-insulated switch case of the present invention directly can reposition conducting rod by first joint sealing, and assembling ejection sleeve pipe is being improved
Also the sealing property of switch-box can be improved while efficiency, the effect for improving a whole set of products security has also been reached simultaneously.
We additionally provide the adjusting process at a kind of quick positioning conducting rod center and ejection cannula center, as shown in Fig. 2
Locking fixture 9 is inserted in the middle part of positioning tool 10, and locking fixture 9 is embedded into upper cover plate by positioning tool 10, under locking fixture 9
Bottom is provided with six square grooves, and six square grooves coordinate with nut 6, and outside operable locking fixture 9 is locking conducting rod and nut and be connected
Busbar.So as to ensure that the concentricity of conducting rod and perforate, then use locking fixture locking nut, it becomes possible to reach from outside adjustment
The effect that conducting rod center is aligned with ejection cannula center.
It is non-slip from external locking locking nut in order to ensure, in a further embodiment, the conducting rod
With the equal-height position of through hole after actual installation, that is, preset the rectangular cross-section of equal-height position (neck can be referred to as), the neck section
Width less than through hole minimum spacing, catercorner length more than through hole minimum spacing, through hole could be arranged to square, rectangular
Shape etc., when locking fixture locking nut, the neck of conducting rod can when rotated be defined the free degree, cutting yet with neck
Face still has the corresponding free degree still less than through hole section in planar movement, does not still affect outside installation.
Described also to include positioning pressuring plate 3 in other further embodiments shown in Fig. 1, the positioning pressuring plate is used
Fix with casing in sleeve pipe will be ejected.Sleeve pipe pressing plate is the sheet material that shape is adapted to support set, and sleeve pipe is ejected in actual applications
Generally triplets, the pressing plate between multiple sleeve pipes can be solid by fixing devices such as screws with integrated design as one block of sheet material
It is scheduled on casing.Above-mentioned design causes ejection sleeve pipe more firm, difficult for drop-off.
Preferably, the material of the nut is brass.Because above-mentioned design is reduced between connection busbar and conducting rod
Contact area, the material of the two contact site needs the electric conductivity more strengthened, but nut needs pre-assembled, repositioning etc. to walk
Suddenly, the well again wear-resisting material of conductance is needed in practical application, therefore fine copper is inapplicable as nut material, here from resistance to
The higher brass of grit is the most suitable.
In further embodiment, upper cover plate is also preset with the stud of pressing plate fixation, will after ejection sleeve pipe is installed
Support set 4 is enclosed within stud, covers sleeve pipe pressing plate 3, lock by panel nut 2 by ejection sleeve pipe tightly be fixed on casing
On.Preferably solve the assembly problem of ejection sleeve pipe.
In some other specific embodiment, the inner side of the embedded division also includes internal thread, and the conducting rod includes outer
Screw thread, is additionally provided with pad between embedded division and conducting rod.Pad can increase some conducting rods and ejection sleeve pipe embedded division it
Between electrical contact pressure, so as to strengthen electric conductivity.The material of pad can be selected as 1mm thick cold-rolled steel sheet 65Mn.
In the specific embodiment shown in Fig. 1, the connection busbar 7 is " Contraband " font, connects lower end and the switch of busbar
Bus connects, and upper end is provided with through hole.Contraband shape enables to connect busbar in upper surface setting through hole, while for assembling,
The debugging space of next prepackage conducting rod is stayed below upper surface, workpeople's assembling is more suitable for.Certainly, in order to realize
Purpose is stated, being designed to the similar scheme such as C-shaped, " 7 " font is all possible, and by such scheme the assembling of the present invention is improve
Efficiency.
Embodiments of the invention are the foregoing is only, the scope of patent protection of the present invention, every utilization is not thereby limited
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
