Abstract
The utility model belongs to the technical field of high pressure electrical equipment, specific is GIS's manual isolator, touch finger, gear, movable contact seat, rack, moving contact, the assembly of stationary contact seat, uide bushing, switching conductor, insulator, manually operation mechanism, insulating axle and the assembly of benzvalene form insulator conductor including shell, spring. Characterized by through manually operation, drives the rack and pinion motion, near and let the moving contact carry out branch closing operation to the state that makes things convenient for the withstand voltage and normal work of GIS changes. The beneficial effects are that: can realize that the on -the -spot withstand voltage test of GIS combined electrical apparatus does not dismantle arrester or voltage transformer repeatedly, volume that reduces site work and to the harm of insulator can not influence electric property and mechanical properties such as the sealing up of insulator, intensity to ensure GIS's wholeness ability. While is than electronic isolator's cost greatly reduced.
Description
Technical field
The utility model relates to a kind of high-voltage electrical equipment technical field, specifically a kind of Manual isolation switch for GIS.
Background technology
GIS is also known as Cubicle Gas-Insulated Switchgear, and it is directly linked to together by elements such as circuit breaker, isolating switch, earthed switches, and be all enclosed in the metal shell of ground connection, fills using the SF6 gas of certain pressure as insulation and arc-extinguishing medium in shell.Many advantages such as GIS is little with its floor space, and reliability is high, installation period is short, are particularly suitable for the transformer substation in city in land used anxiety, transformer station of enterprise, and hydroelectric station, mountain area and the serious area of filth use.Because needing to do flash test after GIS in-site installation, and lightning arrester or voltage transformer can not bear high pressure, so at present this series products when withstand voltage test state, if the isolating switch of not configure dedicated on front side of lightning arrester or voltage transformer, must pull down before test, reinstall after test, a series of repeated works such as scene of causing need repeat to vacuumize SF6 closed air chamber, inflate, moisture solution, leak detection, and before lightning arrester or voltage transformer, increase electric isolating switch cost can be caused to roll up.National grid required because increasing isolation fracture before lightning arrester or voltage transformer from 2014, facilitated field test, for meeting this requirement, devised this kind of Manual isolation switch.
Utility model content
The purpose of this utility model is to provide a kind of simple and reasonable for structure, at resistance to pressure condition without the need to dismantling lightning arrester or voltage transformer, guarantees GIS stable performance, reliably GIS Manual isolation switch.
The technical solution adopted in the utility model is:
The Manual isolation switch of GIS, comprises shell, spring touch finger, gear, moving contact seat, tooth bar, moving contact, static contact seat assembling, fairlead, switching conductor, insulator, manual-operating mechanism, shaft insulation, the assembling of disc insulator conductor etc.When GIS normal operating condition, manual-operating mechanism operates, transmitting gear band carry-over bar and moving contact, makes moving contact insert in static contact seat, forms conduction and connect.When GIS carries out withstand voltage, manual-operating mechanism operates, and transmitting gear band carry-over bar and moving contact, make moving contact leave moving contact seat, forms SF6 clearance for insulation, to isolate lightning arrester and voltage transformer when GIS is withstand voltage, avoids bearing voltage effect.
Concrete, described Manual isolation switch adopts manually.
Concrete, described Manual isolation switch adopts gear driven tooth bar and moving contact structure.
The beneficial effects of the utility model are: manually disconnecting switch operation, reduce on-the-spot withstand voltage complexity, improve the reliability of product quality.And Manual isolation switch is simple to operate, reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, concrete explanation is done to the utility model.

During assembling, first static contact seat assembling 7 is secured by bolts in disc insulator conductor assembling 13, forms fixed contact general assembly.
Two, be bolted on insulator 10 by switching conductor 9, the opposite side of switching conductor 9 is connected with moving contact seat 4 by bolt; Spring touch finger 2 is put into the groove of moving contact seat 4, fairlead 8 is put into the groove of moving contact seat 4; Tooth bar 5 is secured by bolts in moving contact 6, forms moving contact assembling; Moving contact assembling is inserted in moving contact seat 4, spring touch finger 2 and fairlead 8 is assembled with moving contact and contacts, then put into gear 3 at moving contact seat 4 and coordinate with the gear 3 that moving contact assembles, then complete the installation of shaft insulation 12 in turn.Constitute moving contact general assembly.
Three, the insulator 10 of moving contact general assembly part is connected with shell 1 by bolt, then fixed contact general assembly is connected with shell 1 by bolt, again manual-operating mechanism 11 and shaft insulation 12 are coordinated, and be secured by bolts on shell 1, namely complete the Manual isolation switch assembling of GIS.
When manual-operating mechanism 11 operates clockwise, by shaft insulation 12 transmitting gear 3, then make tooth bar 5 move, tooth bar 5 drives moving contact 6 to do rectilinear motion, inserts in static contact seat assembling 7, forms galvanic circle, complete connection layout during GIS normal operating condition.
When manual-operating mechanism 11 operates counterclockwise, by shaft insulation 12 transmitting gear 3, then make tooth bar 5 counter motion, tooth bar 5 drives moving contact 6 to do separating brake rectilinear motion, the moving contact 6 making insertion static contact seat assemble 7 leaves, and forms clearance for insulation, can complete the withstand voltage of GIS.
Concrete, described Manual isolation switch adopts manually.
Concrete, described Manual isolation switch adopts gear driven tooth bar and moving contact structure.
The utility model is not limited to above-mentioned execution mode, anyone should learn make under enlightenment of the present utility model with the utility model, there is identical or close technical scheme, all fall within protection range of the present utility model.
