Description
Technical field
The utility model is related to a kind of deicer for power transmission line, more particularly to a kind of ultra-high-tension power transmission line explosion deicing dress
Put.
Background technology
Ultra-high-tension power transmission line plays vital effect in power network, and the continuation and stability for its transmission of electricity have
Higher requirement.In recent years, year phase in the Spring Festival of serious freezing disaster, particularly 2008 often occurs in south China the greater part
Between the freezing disaster that occurs, cause the provinces such as Hunan, Jiangxi, Guizhou, Hubei, Guangxi, Zhejiang, Anhui power supply major network department or
All interrupt.What current freezing disaster was caused, which have a power failure on a large scale, brings huge loss to national economy, and its main cause is each province
City's main high voltage transmission line of electricity can not be loaded beyond the ice covering thickness of design standard, so that transmission line of electricity weight increases, finally
Forget about it high voltage power transmission bar, tower formation power failure.Ultra-high-tension power transmission line is big all in the severe field of geographical environment, repairing simultaneously
Work is difficult to rapid deployment, and existing deicing equipment is difficult to use.And traditional artificial deicing is typically that operator station stands in
The mode of the enterprising pedestrian's work deicing of transmission line of electricity moving trolley, artificial deicing not only inefficiency but also exists and gets an electric shock and fall
Potential safety hazard.Ice covering thickness is more difficult to carry out by way of artificial deicing clearly compared with macroportion particularly at tuyere position
Reason.Except the de-icing of power transmission lines method that artificial deicing is commonly used at present mainly has heavy current pulse ice-melting method (electro-heat deicing), machinery
Force vibration deicing.It is steel-cored aluminium strand, the wire electricity material and conductivity properties and heat of itself because high voltage transmission line is generally used
Hold, to make wire keep the temperature of higher ice-melt to be not easy very much, and high current electric heating ice-melting method power consumption is huge, to hair
Electric side and power transmission line also have the infringement that can not ignore.Big span, which is deiced, can cause power transmission line to jump and wave;Additionally, due to twisted wire
Power transmission line resistance thermal resistance difference and the difference of extraneous meteorological condition that material inequality is caused so that local ice-melt less effective.Machine
Tool power deicing larger current pulse ice-melt has its relatively good advantage, but conventional mode is by motor-driven rotation impeller
Carry out deicing, it is not easy to remove the ice cube between cable strand, so cause driving wheel securely to catch cable, and then influence whole
The advance of individual deicer.Runner deicing, less efficient, the continuation of the journey to battery pack are driven additionally, due to being powered by battery
Capability Requirement is higher.
Several deicing modes easily freeze for air port etc. above and the deicing effect of the larger position of icing thickness is more bad.
Utility model content
The purpose of this utility model is to provide one kind rapidly and efficiently, reduces labor intensity and be particularly suitable for use in air port etc. easily
Freeze and the ultra-high-tension power transmission line explosion deicer at the thicker position of icing.
This ultra-high-tension power transmission line explosion deicer that the utility model is provided, the device includes insulating wrapped pipe and set
The electric cap and safety explosive of wall disposed within, insulating wrapped pipe axial direction two ends are provided with capping, and insulating wrapped pipe includes card and is
Multiple stress breaches are equipped with the upper lid and lower casing of one, upper lid and lower casing;Detonating primer, upper lid and lower casing seif-citing rate breach
The card and position of place's fracture and upper lid and lower casing burst apart because of impulsive force and the rupture of transmission line of electricity overlying ice sheet is come off.
Come off for the ease of power of assembling and be hit, make the Shang Gai identical with lower shell structure, be semi-circular tube, semi-circular tube
Circumferential direction one end end be provided with ball bumps, the other end be provided with corresponding groove, upper lid and lower casing by ball bumps with it is recessed
Groove clamping is integrated.
Further, it is the breach along the upper lid and the lower casing radial arrangement to make the stress breach.
In order to improve the reliability of explosion, the demolition set is set to include electric cap and safety explosive, demolition set has many
It is individual to be respectively arranged at the stress breach position.
In order to avoid high voltage cable is impaired, make to be provided with protective case at correspondence demolition set position on the insulating wrapped pipe,
Prevent explosive forces from damaging high voltage cable.
Further, had from the electric cap for grand No. 1 electric detonator of core.
In order to avoid the insulating wrapped pipe or icing that come off connect adjacent two cable, make the spacing of the stress breach little
In 2000mm.
As the alternative solution of connection, it is semi-circular tube to make the upper lid and lower casing, and the lower surface of upper lid is provided with projection,
The upper surface of lower casing is provided with corresponding groove;Or the lower surface of upper lid is provided with groove, the upper surface of lower casing is provided with corresponding
It is raised.
During practice, according to weather forecast, when weather forecast shows that this area will have drop sleet weather, by this practicality
It is new to be installed on the high voltage cable that mountain pass is located windward, when icing reaches certain thickness, by track walker's remote-controlled detonation, ignite
Afterwards at upper lid and the equal seif-citing rate breach of lower casing the link position of fracture and upper lid and lower casing burst apart because of the impulsive force of blast make it is defeated
The rupture of electric line overlying ice sheet comes off, and realizes deicing, rapidly and efficiently, labor intensity is low for ice detachment, and effectively solves wind
The problem of mouth etc. easily freezes and is difficult to deicing at the thicker position of icing.
