Along tower body straight down, contact protection completely in falling type protective cover, effectively prevent the invasion and attack of sleet and snow ice to conductor.
Falling type protective cover has also carried out grounding design simultaneously, after opening a sluice gate in place, you can carries out effective grounding, effectively eliminates the sense of ground wire
Answer voltage.
Electric control system is the electrical connection of finishing device, includes control cabinet, dc source, power line, signal wire, lock
Line cabinet etc., after control cabinet is connected with power supply, power line, signal wire joint, you can be manipulated by case and realize upper box-like ground wire
The combined floodgate of ice-melt automatic connection device is with opening a sluice gate.
In transmission mechanism include with auto-lock function turbine worm decelerator make in-place closing after folding conductor all the time
Keep thrust rating；In-place closing control is carried out by switching force；Voltage isolation design has also been carried out simultaneously and power transmission shaft is flexible
Structure design.
Wherein, folding conductor one end is arranged on the ring flange of transmission mechanism output end, and is connected with ground wire, the other end
Adjustable contact is devised, is connected after combined floodgate with upper box-like electricity getting device, so as to realize docking for wire and ground wire.
Upper box-like electricity getting device uses some（It is consistent with wire jumper quantity）Independent hinge type wire clamp hold with a firm grip wire obtain electricity
Stream, by electricity getting device protective cover bottom plate, electric current is guided on fingertip.Upper box-like electricity getting device also contemplates uneven of wire icing
The factors such as power, windage yaw cause correct combined floodgate design when fingertip, contact generation locus deviation, and rainwater refrigerated environment is not
The fingertip protection Design of combined floodgate effect and excessively stream effect should be influenceed.
The effect of folding conductor is：During ice-melt, the connection with upper box-like electricity getting device and ground wire is completed, so as to ensure ground wire
Electric current is obtained from bundle conductor.After ice-melt terminates, upper box-like ground wire deicing automatic connection device is in and opens a sluice gate state in place, folding
Conductor straight down, contact is placed in falling type protective cover and protected along tower body.
In addition, upper box-like ground wire deicing automatic connection device have also been devised manual closing operation prediction scheme.When control cabinet failure, work
Make personnel Ke Dengta at transmission mechanism, open motor shield, take out crank and carry out manual closing operation with opening a sluice gate.This scheme is dress
The successful combined floodgate put provides the guarantee for carrying out a step with opening a sluice gate.
After opening a sluice gate in place, falling type protective cover carries out rain-and-snow protective to folding conductor end contact, and it is arranged on tower body
On the platform in outside, it is placed in below transmission mechanism.
Electric control system is responsible for the combined floodgate of device with opening a sluice gate.Power line, signal wire are protected from transmission mechanism, falling type
Cover is led under tower along steel tower, and is fixed by special clip.When not in use usually, power line, signal wire, which are packed up, is put into
Steel tower is protected in the locking wire cabinet at first cross-arm on ground.
The upper box-like ground wire deicing automatic connection device of the present invention, for the design feature of galianconism cross-arm, to steel tower or connects
Line apparatus is improved design.When ground wire needs ice-melt, staff realizes docking for ground wire and wire, that is, obtains bundle conductor
Upper electric current is simultaneously transmitted on ground wire.
When needing to carry out ground wire deicing, staff removes power line, letter in the locking wire cabinet at the cross-arm of steel tower first
Under number wire terminal to tower, and the control cabinet of electric control system is connected to power supply together, you can in bottom of towe operation control box pair
Device is closed a floodgate, and transmission mechanism drives folding conductor to be rotated up beating box-like electricity getting device upwards, and realization is led, between ground wire
Connection.Now, it can be powered and carry out ice-melt.
After ice-melt terminates, device is opened a sluice gate in bottom of towe operation control box, transmission mechanism drives folding conductor downward
Rotate, folding conductor contact enters in falling type protective cover, opens a sluice gate to stop acting in place afterwards, you can carry out rain-and-snow protective, together
When be grounded.
Because box-like ground wire deicing automatic connection device is specially designed for the steel tower of installation on this, during installation,
The installation of each part is respectively provided with selectivity.During installation, transmission mechanism is arranged on by tower body side by transmission mechanism special fixture
On the platform put up in advance.Folding conductor is hung at transmission mechanism, by bolt by its output end with transmission mechanism
Ring flange is connected, and decelerator protective cover is arranged on into decelerator periphery., will after the heavy punch piece for removing jumper suspension wire clamp both sides
Upper box-like electricity getting device is installed on jumper suspension wire clamp, and some hinge type wire clamps is held with a firm grip split conductor, is guaranteed effectively
Obtain ice melting current on bundle conductor.
It is flat below tower body side, transmission mechanism by special stand and fixture when falling type protective cover is installed
On platform.Power line, signal wire are arranged under tower from device by special fixing-line device, and joint is attached, protected, so
The debugging that laggard luggage is put.During debugging, transmission mechanism position is finely adjusted according to the situation of in-place closing, ensures to touch when closing a floodgate
Head, the correct combined floodgate of fingertip, while ensure that the two offset deviation remains to effectively coordinate in scope of design.According to opening a sluice gate in place
When, protection situation of the folding conductor contact in falling type protective cover, the position of falling type protective cover is finely adjusted, ensured
Effective sleet and snow ice of folding conductor contact is protected, and ensures to design the validity of safeguard procedures in the range of offset deviation.
After each part is debugged, positioning is fixed to each part according to design requirement with regulation fixture.
When ground wire needs ice-melt, staff carries control cabinet and power supply under tower, the lock at the cross-arm of steel tower first
Removed in line cabinet under power line, signal wire joint to tower, and be connected to the control cabinet of electric control system together with power supply.According to
Field working conditions selection operation pattern, then presses " combined floodgate " button, and drive mechanism drives folding conductor from falling type protective cover
In produce upwards beat upwards box-like electricity getting device.After the contact of folding conductor docks in place with the fingertip of upper box-like electricity getting device, close
In place, motor stopping acts lock.Can now be powered ice-melt.
After ice-melt terminates, staff presses " opening a sluice gate " button, and drive mechanism drives folding conductor to rotate down disengaging
Upper box-like electricity getting device, when reaching falling type protective cover, promote revolving door to rotate and close the door, stop afterwards close to switch, motor in place
Stop is made.Now, folding conductor contact covers in falling type protective cover completely, exempts sleet invasion and attack.
