Description
Technical field
The invention belongs to emergency repairing device field, particularly relate to a kind of Portable suspension assembling system for compact combination formula high-tension switch gear.
Background technology
High-tension switch gear is generally divided into air insulated switch equipment (AIS), Cubicle Gas-Insulated Switchgear (GIS, Gas Insulated Substation).In the later stage nineties 20th century, there is a kind of compact combination formula high-tension switch gear (HGIS) in the world.This equipment complex advantage of open type and enclosed switchgear, high voltage device height is integrated, make high-tension switch gear compacter.
Compared with open type switchgear, HGIS(Hybrid Gas Insulated Switchgear, Mixed gas insulation switch) circuit breaker, isolating/grounding switch, CT(current transformer), PT(voltage transformer), lightning arrester etc. is integrated into a module, greatly save floor area, improve equipment dependability; Compared with GIS device, eliminate enclosed bus, greatly save expense.
Visible, HGIS is a kind of high-voltage switch equipment between GIS and AIS.The structure of HGIS is substantially identical with GIS, but it does not comprise bus equipment.Its advantage is that bus is not loaded on SF6 air chamber, and expose, thus wiring is clear, succinct, compact, and serviceability is high.In other words.HGIS product have employed a large amount of up-to-date technologys, makes it structurally have compact, miniaturization, tie cable quantity is few and floor area is little feature, performance has the feature that reliability is high, maintenance is few.
Accordingly, bring charged Distance geometry access path can not meet field activity requirement thus, cause field failure equipment to lift by crane service work to be had a strong impact on, usually require to close on interval in upkeep operation process and accompany and stop, partial circuit crane does not have the problems such as parking space.
For lifting or the maintenance of HGIS equipment, at present domestic generally adopt scaffold erecting, lifting that large-scale crane mode is carried out HGIS equipment.
Adopt that traditional scaffolding erecting is wasted time and energy, man-hour is longer, overhaul efficiency is low, dismounting is still needed after having overhauled, often cause interval power off time long, in partial separation loop, passageway is narrower, because space, place is little, spacing distance is near, large-scale crane is parked without place, is lifted the difficulty that operates, and large-scale crane is difficult to park or suspension arm of crane cannot stretch, and the air wire etc. that easily touching band electrical distance is less cannot realize the quick unloading of malfunction equipment and maintenance.
In real work, for reducing the power off time at interval, equipment place, the examine and replace time of trouble unit must be short as far as possible, therefore need the unloading process of trouble unit must be quick as far as possible and easy, because the space, place of existing substation is little, equipment interval distance is near, large-scale crane is parked without place, lift the difficulty that operates, carry out unloading in the urgent need to a kind of hanging apparatus and change HGIS trouble unit (insulator, current transformer, CB, mechanism etc.) with convenient for maintaining and maintenance, this kind of hanging apparatus must can adapt to the narrow and small working environment of existing substation, need to meet detachably simultaneously, assemblnig requirement, to facilitate baby truck, each for this device loose mail is transported to destination or returns to guard station.
