Description
Technical field
The present invention relates to livewire work fields more particularly to a kind of 10KV outlet cables that are applied to make with overhead transmission line overlap joint
The rod-type arc-extinction device of industry.
Background technology
At present, as the steady progress that country integrally builds, the development of all trades and professions and normal operation are all be unable to do without to electricity
The demand of power, therefore the demand of the guarantee and power grid security to electric power is constantly enhancing, and in the world-class distribution of current construction
Under the overall situation of net, livewire work is particularly important.
Since in city power distribution circuit, pure cable and pure overhead line circuit are less, in order to avoid traffic road junction, important build
It builds or design planning needs, most joint line power supply mode using cable and overhead line, therefore, electrification tears open, takes leap
Cable accounts for daily livewire work larger specific gravity with the work of overhead transmission line joining seam.
When carrying out 10KV outlet cables with overhead transmission line lap works, since the 10kV overhead transmission lines overlapped are in just
Normal working condition, as electriferous state, and the 10kV cables that need to generally overlap, length are longer, capacitance is larger, therefore is overlapping
When due to overhead transmission line electrification and cable capacitance is larger, if not taking ancillary method that can generate great capacitance during overlap joint
Electric current so as to phenomenon of arc discharge occur, has threatened the safety of livewire work operating personnel.Therefore extinguishing arc can be used in sessions
Device, it is therefore an objective to reduce the operation electric current for setting up bypass.
Traditional arc-extinction device can totally be divided into following several under the prior art：Straight hook type Simple hook, manually control disappear
Arc device (is restricted) including manual operation, and insulating bar is unidirectionally fastenedly connected insulating bar and other ancillary equipments, specifically such as
Under：
1. U-shaped structure is presented in straight hook type Simple hook overall construction, and straight hook overall length is longer at back bending, this straight hook
Its overall flexibility of structures shape is insufficient, when carrying out livewire work, the comparatively dense especially top cable space if conducting wire is arranged
Need to will just be linked up with when insufficient, in operating process it is laterally disposed could complete to connect work with conducting wire, but because hook and with rear portion it is whole
Body operating lever is integrated type, so just need to be horizontal by whole device, cause greatly operating difficulties；
2. control arc arrester (restricting including manual operation) manually, is roughly divided into three parts：Closing insulation explosion chamber, simple list
The manual disconnecting link of knife and manual operation drawstring.Entire jumper part-structure is simple, and external label the folding condition of disconnecting link, but sees
Less than the real working condition of internal disconnecting link, determined so all needing to open equipment using the preceding correctness to ensure operation every time
Disconnecting link initial position, increases workload, considerably increases the working time, and jumper outer logo is very under dark surrounds
Hardly possible identification, indirect cause safety to decline, threaten the safety of operating personnel.
3. insulating bar, generally stainless steel, top is rigid connection with hook connection mode, is had no any slow
Flushing device, no buffering leeway, causes entire connection system with meeting certain mechanical strength but exist in actual mechanical process
It overexerts and so that conducting wire generates bounce or swings, cause phase spacing insufficient, there are some potential safety problemss, such as a whole set of
Tool by long-term use, if insulating bar is detached with upper hook because of external environmental factor in the course of work, it will cause
There is greatly security risk in safety accident.
4. unidirectional be fastenedly connected insulating bar, a whole set of arc-extinction device across cable connection ear with being in direct contact device.It is unidirectional tight
Be solidly connected insulating bar connection by adjusting connection hub cone tightness in a conventional manner clamping cables connecting ear homalocephalus or
There is apparent deficiency in the connecting portion on transition bracket, this mode, the range that on the one hand it is applicable in is according to old-fashioned cable
Model, which is set in, has significant limitation today that cable power transmission mode develops rapidly, secondly it can only one direction clamping cables draw
Line can not accomplish all position locked, and there is the hidden danger that cable comes off from side, greatly compromise the safety of operating personnel
Property.And jointing position excessively simply leads to that contact area is relatively small between cable tail and arc-extinction device, directly leads
Current-carrying capacity is caused to reduce, while increases the contact resistance of device and cable tail junction, it is existing that fever is will appear in the course of work
As when external environmental condition is not suitable for, there are serious security risks.
In conclusion arc-extinction device old under the prior art existing serious design defect on hardware facility, with
Tentatively to appear during past distribution uninterrupted operation, serious security risk is will appear after being restricted by environmental factor,
And the versatility of operating efficiency and device in itself is seriously affected since traditional handicraft is coarse.
