The effective way of equipment and grid stability.In distribution uninterrupted operation 4 class, 33 projects, insulating bar working system operation is included
Project 9, covers 3 intermediate items, and accounting is larger.The feelings of aerial lift device with insulated arm can not be applied road is narrow, working space is insufficient etc.
It can be used under condition and step on bar or insulated platform using the progress operation of insulating bar working system, there is irreplaceability.
According to《State Grid Corporation of China's electric power safety producting rule》Regulation, the effective insulated lengths of insulating bar are more than 0.7 meter.Root
According to《State Grid Corporation of China's electric power safety producting rule》Regulation, human body are more than 0.4 meter away from adjacent electrical body.
Insulating bar working system refers to operating personnel and safe distance as defined in surrounding electrical body and grounding body holding, by exhausted
The operation that edge Work tool carries out.Ratchet spanner can conveniently and efficiently dismantle or installation bolt, screw, nut and other screw threads are tight
Hold bolt etc., be in work it is essential, using frequent a kind of instrument.
The mode for being currently used in the jacketed cylinder in insulating bar top fulfils assignment, and limitation is larger and less efficient.Sleeve
The ground potential box spanner placed parallel to insulating bar, can only assemble and disassemble vertical direction bolt, and higher to user's force requirements；
The ground potential box socket set that sleeve is placed perpendicular to insulating bar, the then larger displacement in insulating bar end are only capable of twisting less
Screw, and horizontal direction bolt can only be dismounted.Time-consuming and laborious and operating efficiency is low in the case of two kinds, it is therefore necessary to develops
A kind of new, flexible and convenient to use ratchet spanner uses for insulating bar working system power distribution live-wire.
The content of the invention
In order to solve problem above, the present invention provides insulating bar working system novel ratchet spanner, the tool construction is compact,
Design rigorous, execute-in-place is simple, efficiently.
Technical scheme is as follows：Insulating bar working system novel ratchet spanner, including top are provided with ratchet mechanism
Spanner, the center of the ratchet mechanism is provided with muff joint, and rotary arm coaxial package is described in the outside of ratchet mechanism

Technical solution of the present invention further includes：The bottom of the spanner is provided with deflecting structure.
Technical solution of the present invention further includes：The deflecting structure includes the plum blossom connector installed in spanner bottom, the plum
Flower connector is connected by bolt with connecting rod.
Technical solution of the present invention further includes：The plum blossom connector is porous plum blossom connector, there is folder between each plum blossom hole
Angle.
Technical solution of the present invention further includes：The deflecting structure includes the directive wheel installed in spanner lower end, the guiding
Wheel coordinates with insulating cord.
Technical solution of the present invention further includes：The directive wheel is oriented to wheel for epoxy resin.
Technical solution of the present invention further includes：The both sides at the ratchet mechanism center are mounted on muff joint.
Beneficial effects of the present invention are：The present invention provides insulating bar working system novel ratchet spanner, new tool uses
Ratchet mechanism, rotary arm is added on the premise of bolt torque is ensured, has innovated leverage, flexibly compact, side
Just, vertical drawing can complete the fastening work of bolt etc. during operation, breach conventional spanner and arduously twist or need significantly laterally
It is the defects of mobile, time saving and energy saving, effectively increase the work efficiency that insulating bar working system carries out livewire work.
Novel ratchet spanner can not only complete Conventional insulation bar working system operation, to wire clamp common in summer peak meeting,
The defect elimination work of bolt looseness fever etc. has more advantage, improves the efficiency of power distribution network defect elimination, has ensured the peace of distribution network operation
Entirely；Assembly and disassembly bolt has been started from horizontal displacement mode or has twisted transformation of the pattern to vertical drawing pattern, has been considerably improved
Livewire work efficiency.
The instrument can also generate heat, in the case of conducting wire easy fracture in wire clamp at the same time, be used in aerial lift device with insulated arm operation, long distance
From defect elimination is carried out, operational security is improved, is had wide range of applications.
Novel ratchet spanner, reduces on-site personnel powered time for carrying out operation in highfield, reduces work
The working strength of industry personnel, improves work efficiency；And in the defect elimination operations such as wire clamp fever, bolt looseness, the fever such as conducting wire
Easy fracture, new tool, which does not have to close contact, can complete defect elimination operation, further ensure personnel's job safety.
By electrical test and mechanical test, result of the test meets electric power safety code, and security reliability is high, meets powered
Job safety required distance.The instrument is formed using the livewire work combinations of materials such as common insulating cord, insulating bar that work, and is made
Of low cost, flexibility is strong, is applicable in scene extensively, has high promotional value.
