Specific embodiment
Referring to Fig. 1, the inventor of the utility model is in order to preferably managing the technical solution of the utility model
Solution, is described in detail below by specifically embodiment, and with reference to attached drawing：
A kind of switchgear operation tool set of the utility model, including universal handle 1 and operates switchgear
The connector 2 of all models, universal handle 1 include the handle body 11 set gradually, pars contractilis 12, swing transition piece 13 and connector
Socket 14.The wherein first end of handle body 11, i.e., the first end of universal handle 1, equipped with along 1 diametric(al) of handle body
The operation rod through-hole 111 of body 1 is extended through the handle, the operation lever insertion operation rod through-hole 111 of insulation is rotated by the operation lever
Universal handle 1, it is more laborsaving when being operated to switchgear.When can be also prevented simultaneously with crank Operation switch cabinet, insulating glove
The problem of being wound with crank.The radial outside of handle body 1 should not be socketed tubular part to increase handle body 11
Torsion.
The first end of pars contractilis 12 is co-axially inserted the second end of handle body 11, on the outer circle wall of handle body 11
Equipped with axial direction and axial parallel, the sliding slot 112 of kidney ellipsoid of handle body 11, radially connected handle body 11 is equipped in sliding slot 112
With pars contractilis 12, can in the sliding slot 112 sliding and the fixed buckle 113 in any position in sliding slot 112, such design,
Ensure that the scalability of universal handle 1, thus can according to the distance between high-tension switch cabinet crank handle hole and ground,
The length that pars contractilis 12 stretches out handle body 11 is adjusted, convenient for operation maintenance personnel execute-in-place.
The energy storage hole 121 of the regular hexagon parallel with operation rod through-hole 111 is additionally provided on pars contractilis 12.
It is connected between the second end of pars contractilis 12 and the first end for swinging transition piece 13 by the first axis pin 15, makes pendulum
Moving part 13 can be swung in the range of ± 90 degree.First axis pin 15 is parallel with operation rod through-hole 111.Swing transition piece 13
It is connected between the second end and connector socket 14 by the second axis pin 16, connector socket 14 is enable to be carried out in the range of ± 90 degree
It swings.Second axis pin 16 and the 15 orthogonal setting of the first axis pin.The effect of connector socket 14 is to block to carry out switchgear
The connector 2 of operation.
The purpose so designed is：
First, instead of crank, switchgear is operated by the connector 2 that can be detachably connected with connector socket 14
The connector 2 of all models can be assorted once and universal handle 1 is loaded in a tool box, and connector 2 live can in real time be replaced,
It prevents the generation of tape error crank, reduces the grid switching operation time.
Second, connector 2 can realize steering, and the convenient narrow space in switchgear implements operation.It prevents from passing through rotation
When crank operates switchgear, stress point in same axle center, does not cause the generation for rocking deflection or even de- handle, extends switch
The service life of electrical equipment in cabinet.
Universal handle 1 and connector 2 reach the 40Cr steel one-pass moldings of HRC 28-32 using hardness by quenching treatment
It is made.Universal handle 1 uses ergonomic designs, and operation is comfortable and is Lengthened moment arm type, and more laborsaving, wide usage is stronger.
The spring bayonet socket that the use of connector socket 14 and connector 2 is located at 14 top of connector socket is fixed, between connector socket 14 and connector 2
It is firm to contact.The quick-replaceable of connector 2, and meet the operation of polytypic switchgear.
Be divided into three classes earthing switch blade connector, energy storage connector and the case of connector 2 becomes operation connector.
The axial both ends of connector 2 are respectively and 14 fixed retaining mechanism connecting pin 21 of connector socket and operating side 22.
Since the cross sectional shape of the spring bayonet socket on connector socket 14 is regular hexagon, no matter connector 2 is ground connection lock
Knife connector, energy storage connector or case become operation connector, and retaining mechanism connecting pin 21 is all the regular hexagonal prism coaxial with connector 2, prevent
The only rotation in connector socket 14 of connector 2.
No matter connector 2, which is earthing switch blade connector, energy storage connector or case, becomes operation connector, and the shape of operating side 22 is necessary
With handcart on switchgear or disconnecting switch or the form fit of grounding switch operating position, operating side 22 can be same with connector 2
The cross sectional shape of the column or blind hole of axis, column or blind hole can be circle, regular hexagon, kidney ellipsoid etc..It can also grasp simultaneously
Make to process groove, step surface etc. on the end face at end 22, so that connector 2 can be with handcart and disconnecting switch, the operation of grounding switch
The form fit at position.
A kind of switchgear operation tool set of the utility model is equipped with replaceable connector 2 by universal handle 1 and is applicable in
Property it is quite extensive, wide usage is very high, disclosure satisfy that most switchgears, handcart operation.Secondly because universal handle 1 uses
By quenching treatment, the 40Cr steel one-pass moldings that hardness reaches HRC 28-32 are made, and chromium plating process is passed through on surface, therefore
Good mechanical performance, and with flexible extension bar, extended type operation stick, suitable for different occasion requirements.This practicality simultaneously
A kind of new switchgear operation tool set has enough mechanical strengths, can be widely applied to switch-cabinet grounding plug-in strip point
Conjunction, handcart operation and killer switch stored energy operation etc..Production efficiency is effectively improved, avoids security incident, is met
The lean of enterprise, efficient management requirement, generate good economic and social benefit.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this practicality is new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all fall in the Claims scope of the utility model.
