Description
Technical field
A kind of quick detachable easy-to-maintain isolation switch contact rain cover device is the utility model is related to, belongs to technical field.
Background technology
GW4 type disconnecting switch, is a kind of double-column horizontal rotation type disconnecting switch, and the quality of contact part directly affects conduction
The performance in circuit, contact part generally have the parts such as fingertip, spring, to ensure its reliable electric conductivity and good work
State is, it is necessary to install rain cover additional.The function of rain cover, is exactly rain-proof as its name suggests.
GW4 types disconnecting switch manufacturer is different at present, and form is also different, the rain cover one of old type tube disconnecting switch
As be aluminum, full-closed structure, is sleeved on conducting rod, is fixed with 2 support pin screws.Its major defect has at following 4 points.
1st, oxide, etching conductive bar are produced.Rain cover is fine aluminium, and conducting rod is fine copper, both are nested together, and can be produced
Side effect, because as copper and aluminium are linked together with simple mechanical means, particularly in humidity and environment containing salinity
(always containing certain moisture and a small amount of soluble inorganic salt in air), this butt joint of copper, aluminium is equivalent to be immersed in electrolysis
A pair of electrodes in liquid, will form potential difference (equivalent to 1.68V primary batteries).Under Galvanic interaction, aluminium can soon lose
Betatopic and be corroded so that electrical connector is slowly relaxed, cause contact resistance to increase.When flowing through electric current, connector hair
Heat, temperature rise can also cause the plastic deformation of aluminium in itself, more increase the contact resistance of junction portion.Such vicious circle,
Untill joint area is burnt.Substantial amounts of oxide can be also generated in rain cover and conducting rod contact portion, when serious, can be made
Both combine together, corrode contact site, substantially reduce conductive copper bar current capacity.
2nd, dismounting is difficult.When contact part seriously generates heat or needs disassembling overhaul, after just rain cover must be removed
It can carry out.On the one hand, zinc-plated 6mm support pin screws, do not tear open any more, after can only mostly removing by force already after exposing to the weather in outdoor
In addition perforate, tapping again, it is difficult to restore；On the other hand, the oxide of generation is seriously accumulated, and is even struck and is also torn open not with hammer
Get off, finally can only cut rain cover with cutting machine, also add the cost input of spare unit part.
3rd, the repair time is extended.It is whole on the premise of rain cover is not destroyed, complete due to rain cover it is difficult to remove
The substantial amounts of time, will certainly be wasted in the dismounting of rain cover by conducting rod Disintegration overhaul.
4th, it is unfavorable for maintenance repair.Periodicmaintenance light maintenance for disconnecting switch, since rain cover is fixed, one
As can not possibly be removed, can only be cleaned, examination and maintenance to exposing the part of visible range, do not reached comprehensive inspection
Repair maintenance effects.
Existing isolation switch contact rain cover device design feature is：1st, rain cover；2nd, fixed screw.Rain cover remove with
Afterwards, the parts of the inside could be carried out maintenance.
Another rain cover device design feature is：1st, rain cover；2 fixing bolts；3 fixture blocks.Screw is zinc-plated material, cruelly
It is difficult to pull down to be exposed at outdoor basic serious corrosion, i.e., can pull down, be also impossible in regular maintenance after removing to inside zero
Component inspection, therefore it is not easy to regular maintenance.
Utility model content
Designed the purpose of this utility model is to overcome above problem it is a kind of it is easily disassembled, convenient to overhaul, prevent
The rain cover of etching conductive bar.
Existing isolation switch contact rain cover device design feature is：1st, rain cover material is generally aluminum products, and surface is done
Simple spray painting processing, for a long time in solar exposure and erosion by wind and rain, accelerates its aging, produces substantial amounts of oxide, etching conductive
Bar；2nd, it can not fold and be unfavorable for overhauling contact 3, installation and removal more trouble, it is necessary to conducting rod be pulled down, then be inserted in and led
Electric pole, is unfavorable for overhauling, increases workload；4th, fixation is extremely simple, is only fixed by two normal screws, fixed not firm easy
Loosen, screw easily gets rusty, and adds dismounting difficulty.
For the disadvantages described above of the prior art, the utility model is the special equipment for isolation switch contact.The rain-proof
Cover material uses polytetrafluoroethylene (PTFE), increases its anti-aging and corrosion resistant ability, greatly improves its service life.And increase
Hinge function, can be more than 90 degree of foldings, easy access contact, greatly improves the convenience of work, reduce work
Amount.It is extremely simple convenient to install, and without dismantling conducting rod, directly fixed pedestal is installed on conducting rod.Consolidated using hinge type
Determine method, fixation is not easy to loosen or loosens.
In order to solve the above technical problems, the utility model provides a kind of quick detachable easy-to-maintain isolation switch contact rain cover
Device, it is characterised in that including conducting rod, fixed pedestal, rain cover, the conducting rod, the rain cover are arranged at described solid
Determine the right side of pedestal, the left end of the conducting rod is connected with the fixed pedestal, and the rain cover nesting is arranged at described
The outside of conducting rod, the left end of the rain cover are connected with the fixed pedestal.
As a kind of preferred embodiment, loose-leaf, fixed pedestal are provided with by hinge between fixed pedestal and rain cover
It is rotatablely connected by loose-leaf and rain cover.
