Abstract
The utility model discloses a kind of high voltage isolator, and this high voltage isolator comprises base, is fixed on two insulation columns on base, be separately fixed on two insulation columns into and out of line terminals, and for the disconnecting link between two-terminal; Described disconnecting link to be hinged on outlet terminal and to form the rotational structure being radius for the center of circle with itself length with the pin joint on outlet terminal, thus the contact realizing disconnecting link and input terminal be separated, reach the object of circuit communication or disconnection; Described disconnecting link comprises two metallic conduction sheets in yi word pattern structure, thus forms yi word pattern disconnecting link structure.Described in the utility modelly all adopting " one " word structure into and out of line terminals and disconnecting link, making electric current constant from entering out maintenance direction, electric-field intensity distribution is even, and it is stable that insulation property improve, loop resistance reduces, electric power direction is conducive to switch.
Description
Technical field
The utility model relates to a kind of high voltage isolator, divides belong to outdoor AC high-voltage technical field by International Patent Classification (IPC) (IPC).
Background technology
In electric power system, high voltage isolator is a kind of indispensable visual plant.When the work such as interruption maintenance, renewal of the equipment, increase-volume, load switching, Power convert need be carried out in certain line loop of power circuit or certain section of loop, in order to not affect the normal power supply in other loops, must be had a power failure isolation, reached the object of safe construction, and this just needs isolation to realize.The isolating switch run in current power system is due to design or manufacture, and also there is many defects, as blade and fixed contact loose contact, such that switch generates heat seriously, malfunction; Electric current changes repeatedly from entering outgoing direction, and make the skewness of electric field, insulation breakdown happens occasionally; Electrodynamic direction is also the problem such as stable being unfavorable for switch, and need the unit being engaged in switch designs and manufacture to constantly bring forth new ideas, making great efforts exploration can better isolating switch.
For this reason, inventor is organizing research staff to carry out studying and improving always, and successfully have developed 12kV isolating switch GW9A-12/630-20 outdoor AC high-voltage isolating switch of new generation.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of high voltage isolator, it all adopts " one " word structure into and out of line terminals and disconnecting link, make electric current constant from entering out maintenance direction, electric-field intensity distribution is even, and insulation property raising, loop resistance reduction, electric power direction are conducive to the stable of switch.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high voltage isolator, this high voltage isolator comprises base, is fixed on two insulation columns on base, be separately fixed on two insulation columns into and out of line terminals, and for the disconnecting link between two-terminal; Described disconnecting link to be hinged on outlet terminal and to form the rotational structure being radius for the center of circle with itself length with the pin joint on outlet terminal, thus the contact realizing disconnecting link and input terminal be separated, reach the object of circuit communication or disconnection; Described disconnecting link comprises two metallic conduction sheets in yi word pattern structure, thus forms yi word pattern disconnecting link structure.
Further, described two metallic conduction sheets be arranged in parallel, and are connected by metal connecting piece, thus form disconnecting link structure.
Further, the outside of described each metallic conduction sheet all offers groove, forms the metal sheet that outer surface caves in.
Further, described recess sidewall and its plane perpendicular.
Further, the bottom surface of described groove offers the bar shaped depression that transverse and longitudinal is interspersed, described each sidewall of bar shaped depression and the plane perpendicular of this depression are arranged.
Further, the described metallic conductor being in-line shape into and out of line terminals.
Further, be describedly a red copper section bar lamellar body in yi word pattern into and out of line terminals, described red copper section bar lamellar body locks respectively on two insulation columns.
Further, described red copper section bar lamellar body its be surface light gliding mass.
Compared with prior art, advantage of the present utility model:
1, described in the utility modelly all adopting " one " word structure into and out of line terminals and disconnecting link, making electric current constant from entering out maintenance direction, electric-field intensity distribution is even, and it is stable that insulation property improve, loop resistance reduces, electric power direction is conducive to switch;
2, this novel also in disconnecting link any piece of metal conducting strip outer surface on offer groove, and the setting perpendicular to the ground of the sidewall of groove, form the disconnecting link structure of red copper section bar, then through mould, salient point is gone out at contact two ends, make the mechanical performance of blade, electric conductivity obtains large increase.
