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