Description
Technical field
The present invention relates to a kind of instrument, particularly a kind of new tool that reduces SF6 cyclinder gas residual rate.
Background technique
In recent years, along with the continuous renewal of socioeconomic development and power equipment technology, newly-built electric substation and old transformer station technological transformation sulphur hexafluoride (SF6) electrical equipment came into operation in enormous quantities.Because sulphur hexafluoride (SF6) gas has remarkable electrical insulating property and arc quenching characteristic, in power industry, by the extensive insulating medium as electrical equipments such as switches, to be used, the storage of SF6 gas is to use special cylinder.
When the new GIS equipment of installing, SF6 switch and CT or operational outfit has after Leakage Gas, all need equipment to fill SF6 gas.In gas replenishment process, tend to occur the icing phenomenon of SF6 steel cylinder afterbody.After freezing, can cause the gas in steel cylinder not to be filled into completely among equipment, interior of steel bottle has a large amount of gas residue wherein, has caused very large waste.SF6 gas bottle heating device is that a kind of automatic temperature-adjusting is controlled, the small handcart of external heating electric heating gas cylinder (Φ 220 * 1450) use, and this small handcart is applied to power industry sulphur hexafluoride and by gas cylinder, is filled with the occasion of the equipment such as high-voltage switch gear.When the liquid sulphur hexafluoride in gas cylinder is filled with high-voltage switch gear, sulphur hexafluoride becomes gaseous state from liquid state, absorb amount of heat, if without the continuous additional heat of external heat source to gas cylinder, in gas cylinder, residual most sulphur hexafluoride cannot be discharged, carry out supplemental heat source in the past with petrol burner heating gas cylinder, hot area is inhomogeneous,, also there is potential safety hazard in inefficiency.
Summary of the invention
Object of the present invention will overcome the above problems exactly, a kind of new tool of reduction SF6 cyclinder gas residual rate of removable, adjustable thermostatic heating equipment is provided, when filling SF6 gas, steel cylinder is heated, both can realize device security tonifying Qi fast, can fully use SF6 gas again, reduce volume of rest gas in steel cylinder.
Technological scheme of the present invention is achieved like this: a kind of new tool of the SF6 of reduction cyclinder gas residual rate, is characterized in: it comprises vertical gas cylinder 1 heating small handcart 9, be contained on heating small handcart three groups of heaters of electric control cubicle 8, upper, middle and lower of 9; Heater consists of separating-closing type heater band, at the outer surface of heater band, thermal insulation layer is housed; Temperature probe W is arranged in the heater band of top, and digital display temperature controller is contained in electric control cubicle 8, and controlling Temperature Setting scope is 10-35 ℃; Right flank at top heater band is equipped with a protective switch that plays safety protection effect.
Mode of heating of the present invention is external heating, heating unit adopts stainless steel heating collar, multi-disc heater band is harmonious up and down, gas cylinder to be heated is sandwiched in wherein, gas cylinder is carried out to homogeneous heating, temperature controlling instrument is automatically controlled and is shown heating-up temperature simultaneously, makes gas cylinder be constant at a certain setting temperature, until the sulphur hexafluoride in gas cylinder is all discharged.Fund input is little, and simple structure is easy to use, can be applicable to the inflation of sulphur hexafluoride equipment microthermal climate, the tonifying Qi work of electric substation of electric company.There is no at present same type operating system, as special design production capital drops into larger.Therefore this sulfur hexafluoride gas cylinder heating device has the advantages such as economic, practical, stable, reliable, has very strong actual application value and promotional value.The present invention adopts portablely, and cost is low, easy to use, be easy to carry; Be easy to fast aeration, be convenient to site examining and repairing and maintenance.

Embodiment
From Fig. 1 to Fig. 3: the present invention includes vertical gas cylinder 1 heating small handcart 9, be contained in heating small handcart three groups of heaters of electric control cubicle 8, upper, middle and lower of 9; Heater consists of separating-closing type heater band, at the outer surface of heater band, thermal insulation layer is housed; Temperature probe W is arranged in the heater band of top, and digital display temperature controller is contained in electric control cubicle 8, and controlling Temperature Setting scope is 10-35 ℃; Right flank at top heater band is equipped with a protective switch that plays safety protection effect.
Electric control cubicle comprises safety fuse cutout, power supply indicator, RCCB, ammeter etc., the alternating current ammeter of three 0～10A is housed on panel, indicate respectively each phase current values of three-phase electricity, the indication of running current table is identical, if any ammeter indication, be not inconsistent, whether the heating collar of searching on this circuitry phase works.
When small handcart normally uses, perpendicular to ground, gas cylinder base lies against on ground, driving wheel 7 supplemental support of two Φ 250.During handling gas cylinder, unclamp and screw nut 3, with handle 4, pull open lid, the cylinder neck of a hand steered setting being firmly housed to, the another have gentle hands gas cylinder that gently rolls, makes gas cylinder enter small handcart 9, close the cover completely, tighten and screw nut 3, complete gas cylinder and pack into, can put into operation.Gas cylinder carriage is welded by square tube and pipe; Heating part is comprised of the identical six semicircle heater bands of shape, every two complete heating collars of composition that interlock up and down, and the heating power of every is 1000W, total heating power is 6KW, by temperature controller, according to the temperature setting in advance, is automatically controlled.
Heating-up temperature is set in 35 ℃, when cold conditions just starts, heating drops into (six heater bands are all switched on) simultaneously, be heating with full power, when temperature rises to 35 ℃, heater disconnects, and heater band stops heating, the waste heat of heater band can make temperature keep a period of time, when temperature is during lower than 30 ℃, heating starting, and keep temperature constant at 35 ℃ within the scope of 30 ℃.
Outer surface at heater band is equipped with thermal insulation layer, in case heat loss and cause because of carelessness scald.Electric control part is divided and is concentrated in electric control cubicle; Temp probe is arranged in the heating collar of top, and digital display temperature controller is contained in electric control cubicle, is a kind of digital temperature control instrument, and control and measurement temperature is accurate.Temp probe and temperature controller form thermometry and the control of system.The scope of controlling temperature can be set by the user, and with reference to the scope of controlling temperature, is 10-35 ℃; Right flank at top heater band is equipped with a protective switch, plays safety protection effect, and when gas cylinder to be heated packs into after small handcart, close the cover, only has after lid closes tightly, and protective switch is just closed, and the power supply of all heater bands can be served, and starts Automatic-heating.After sulphur hexafluoride in gas cylinder is all discharged, gas cylinder need unload from small handcart, as long as uncap, protective switch disconnects immediately, and the power supply of all heater bands disconnects, and at this moment can unload safely gas cylinder.
