Gear 43 screens when just complete whole separating brake process, formd between support 22 and fingertip 31 one it is visible isolate break
Mouthful.Arrester 3 is also realized with conductive major loop and separated.
During closing operation, because in the presence of back-moving spring 52, the spacer pin 76 of pulling buckle 7 is in the inner close fitting lower opening of lower opening 75
75 inwall, the operating physical force of such load cutter is acted directly on plug-in strip 5, plug-in strip 5 is rotated around stop block 43, plug-in strip 5
On contact 51 first be embedded in arrester 3 fingertip 31, realize electrical connection.Plug-in strip 5 continues to rotate, plug-in strip 5 and upper contact head 21
Face is contacted, and realizes the electrical connection of conductive major loop.In the process, work of the meeting of latch hook 62 of lock 6 in back-moving spring 52
With it is lower surround the first bearing pin 61 rotation slip into the lockhole 221 of support 22 so that realize plug-in strip 5 contacted with the face of upper contact head 21 and
Locking, it is ensured that a kind of cable for mounting area arrester of the invention with overhead line all insulation clutch in angle mount, upside-down mounting,
Plug-in strip 5 will not be acted on because of own wt, vibrations and electric power etc., and latch hook 62 is separated with lockhole 221.
A kind of cable for mounting area arrester of the present invention and overhead line all insulation clutch.In "on" position,
High-pressure side electric current is connected conducting with overhead line by upper contact head 21, plug-in strip 5, is insulated with the earth, completes the conveying of electric power.Work as generation
When thunderbolt or switching overvoltage, the arrester 3 that insulation characterisitic is usually presented shows its excellent nonlinear characteristic, and it is internal excellent
Good metal oxide resistance quickly shows to be converted from high resistance to low resistance, and the small increase of voltage can cause electric current to increase
The mutation of big several orders of magnitude, now arrester 3 be mutated by insulation bulk properties conductor 801 characteristic, overvoltage passes through 3 pairs of arrester
The earth discharges, and when the threshold value of voltage landing to resistor disc, then occurs reversals, the small reduction of voltage can cause resistance
It increased dramatically, arrester 3 becomes insulation bulk properties again by conductor characteristics, so as to maintain the normal operating conditions of power system.
A kind of cable for mounting area arrester of the present invention and overhead line all insulation clutch, can be power grid construction
Bringing reduces cost, reduces construction intensity, convenient maintenance inspection and fast searching buried cable trouble point, reduces power failure face
Beyond product, shortening power off time are there is provided system security reliability etc., the generation of ground short circuit can be also reduced.
In a kind of cable for mounting area arrester and overhead line all insulation clutch of the present invention, upper contact head 21 is with
Contact 41 selects high-quality copper busbar, and purity is high, conducts electricity very well, and case hardness is high.Plug-in strip 5 uses cathode copper pultrusion,
Increase intensity and rigid flange are also devised with the both sides of plug-in strip 5, it can be ensured that remain to be reliably connected in the presence of electric power.
The surface of all conductive major loop parts is handled using silver plating process, can effectively reduce contact resistance, is increased antiseptic property, is carried
High power supply reliability.Upper supporting column insulator 2 and lower supporting rod insulator 4 are made by large distance composite material, lightweight, resistant
Ability is strong.Underframe 1 is handled using hot dip galvanizing process, and antiseptic property is good, and service life is long.Pulling buckle 6 and lock 7 are suppressed using cast steel
Shaping, forced position and rotating fulcrum no-float, operational torque is reduced using lever principle, is conducive to plug-in strip 5 to be avenged in frost
Reliable separating brake under hail hazard weather.With reference to the handling characteristics of load cutter, with reference to the mounting means of fuse switch, bottom
The bottom surface of frame 1 is added with certain installation connecting plate 11 for installing gradient.
Second embodiment
The difference of second embodiment and first embodiment is:The top surface of upper supporting column insulator 2 adds covering upper contact head
21 and the upper insulating boot 23 of support 22.Upper insulating boot 23 and support 22 are contour.Upper insulating boot 22 is provided with close to the side of arrester 3
One opening for the progress breaking-closing operating of plug-in strip 5.The top surface of lower supporting rod insulator 4 adds covering stop block 43 and lower contact 41
Lower insulating boot 44, drop bar 42 passes lower insulating boot 44 upwards, plug-in strip 5 in addition to the position contacted with the face of upper contact head 2, all
Insulation sleeve 53 is coated, draw ring 74 passes insulation sleeve 53 upwards, and contact 51 passes insulation sleeve 53 downwards.Pass through above-mentioned technology hand
Section, realizes a kind of cable for mounting area arrester of the present invention and all insulation of overhead line all insulation clutch, it is ensured that
A kind of cable for mounting area arrester of the present invention is entered with overhead line all insulation clutch under moist meteorological condition
Security during row load operation.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
