1. Product introduction
LHJG series of power grid foreign body laser removal instrument is specially designed for the rapid removal of foreign bodies in exposed power grid. It provides an ideal high-efficiency remote laser foreign body removal instrument for maintaining the safety of power grid and high-speed railway lines.
LHJG series power grid foreign body laser removal instrument using fiber laser as the light source, the use of air-cooled, compact structure design, its electro-optical conversion efficiency is higher than 35%, and maintenance-free operation and other characteristics, cost-effective, far superior to other types of the same power laser. It adopts the international standard optical fiber QBH output head, the wireless controller controls the laser, and the focusing machine vision amplification system is adopted, and the clearing distance can reach 300m.
 

2. Precautions for product transportation

The output fiber of a laser is a very sensitive and critical component. When the laser is installed, transported, packaged, and worked, the bending radius of the output fiber must be no less than 30cm, otherwise the laser will be easily damaged. At the same time, the tail and root of the laser output fiber should also be careful not to bend, otherwise the laser will be damaged. If the laser needs to be returned to the factory, it is recommended to use the original packaging materials. If there is no original packaging material, the laser body and the output optical isolator need to be packaged with suitable soft materials to avoid transportation vibration damage to the laser.

B. Precautions for battery transportation:

The battery transportation needs to do a good job of filling, anti-collision and other measures to avoid the battery by violent collision or vibration;

② The battery can not be charged immediately after the battery is discharged from the outdoor high temperature or at high temperature, and it can be charged after the battery temperature is cooled to room temperature;

When the battery is stored, it can be placed in a dry and safe room (low temperature storage will not damage the battery, but the battery temperature should be increased when using), and it should be placed in the shadow as much as possible when using outdoors to avoid direct sunlight. The battery temperature is too high.

3.4. Introduction to the aiming system The tablet computer can enter the parameters that can be set by the aiming system through wireless connection:

(1) Set the PTZ speed;

(2) Set the laser power;

(3) Set the automatic cutting start point and end point;

(4) set up electronic fence. By setting the speed of the gimbal, the gimbal can be moved accurately to lock the target accurately. Through the "photo" and "video" function can record the scene.

3.6. Electrical connection distributor components mainly include batteries, laser power lines, etc. as shown in Figure 6. The battery mainly supplies power to the laser; the function of the laser control panel is to control the switch of the laser; the laser power line is connected to the 48V power output end;

3.7. Function and Use of Laser Control Box After the laser is powered on, turn the emergency switch to confirm whether it is normal. The key switch mainly controls the turning on and off of the laser. When the key is turned to ON, the POWER lamp is on. When the laser is emitted, the EMISSION lamp is on. When the laser is turned off, the EMISSION lamp is off. If the laser needs to be stopped in an emergency, the red emergency switch can be used. Figure 8:

9. After opening the main chassis cover, take out the laser gun head and install the laser gun head on the pan-tilt bracket, then take out the DC line and the spiral line, connect them to the interface between the gun head and the pan-tilt respectively, and finally take down the protective cover of the laser gun head.

10. After completing the 5.9 steps, you can turn on the tablet, connect the wifi transmitted by the camera, and turn on the aiming system.

11, through the tablet computer direction touch key control pan-tilt rotation, aiming at the target. as shown in Figure 10.

14. The method of turning off the laser is to turn off the laser light output button on the flat panel control panel first, then turn the key switch of the laser control box to the OFF position (as shown in Figure 13), and finally turn the air switch at the lower right corner of the protection box to the down position (as shown in Figure 14) to complete the laser equipment turning off.

15. Put the laser output head, tablet computer, chargers and connecting wires into the designated packing box.

16. The removal of foreign objects in the laser power grid is completed.

4. Precautions

a Power-on sequence: close the air switch at the lower right corner of the protective box, and then turn on the key switch. The mobile power supply is a special power supply for the laser cleaner, and cannot be used for other high-power electrical appliances.

B. During the operation of the power grid foreign matter laser remover, it shall be cut back and forth along the joint surface of the foreign matter and the wire. If it is unavoidable to act on the wire, it is forbidden to act on a certain point on the wire continuously for a long time.

c. It is strictly forbidden to directly apply laser to power equipment with insulating layer such as insulators during foreign matter treatment.

D when the steel strand (such as ground) surface corrosion or damage, will greatly improve the absorption rate of the laser beam, such as foreign matter in the process of laser inevitably to sweep to the steel strand (such as ground), should immediately turn off the laser.

5. Common fault handling methods

1. The main inspection and solution of the laser without light:

a. Check whether the emergency stop switch of the laser is closed;

B. Check whether the laser key switch is normal;

c. Check whether the air switch of the laser is normal.

2. The main reasons for the reduction of laser power and treatment measures:

a. Check whether the power supply is stable and whether the current reaches the rated working current;

B. Check whether the protective mirror surface of the laser gun head is polluted. If there is any pollution, wipe it gently with mirror paper or with mirror cloth dipped in anhydrous ethanol, and do not scratch the mirror film layer;

C. Check whether other optical lenses of the whole equipment are polluted, such as laser focusing lens;

D. confirm whether the laser has been used for more than 20000 hours, such as the use of more than 20000 hours of power attenuation is a normal power loss.
