Garden lights are very beautiful, but if you do not pay attention to some details, it is very simple to present the problem.

First, common problems

   There are two kinds of common problems: one is high resistance problems; The other is low resistance. The so-called high resistance fault, that is, the cable is burned, the outer measurement resistance is larger, or the insulation is reduced between phases or to the ground, but there is a certain resistance value; The so-called low resistance fault, that is, the wire is short or completely short to the ground, the current increases, and the power supply shows trip scene. These two problems and their frequent appearance threaten the normal use of garden lights. Therefore, it is necessary to pay sufficient attention to find out the elements and countermeasures.

Two, the main elements of the courtyard lamp fault

   1. Poor construction quality

The proportion of defects caused by construction quality is larger. The main performance: first, the depth of the cable trench is not good, and the sand cover brick is not constructed according to the specifications; Second, the manufacture and device of the aisle tube do not meet the request, the two ends are not made according to the specification of cough mouth; Three is to lay the cable on the ground dragging; Fourth, the embedded pipe at the bottom of the foundation is not constructed according to the requirements of the code. The main reason is that the embedded pipe is too thin, coupled with certain bending, it is appropriate to wear the cable, and the situation of “dead bending” at the bottom of the foundation; Five is the line nose crimping and insulation wrapping thickness is not good, after long-term operation will phase short circuit.

2. The data is not qualified

From the problems dealt with in recent years, the low quality of data also has a lot of factors. The main performance is: wire containing less aluminum, wire is relatively hard, thin insulation layer. This situation is relatively widespread in recent years.The quality of supporting engineering is not excellentPatio light cables are usually laid on sidewalks. Sidewalk construction quality is poor, the ground subsidence, the cable deformation, resulting in cable armor. In particular, the northeast region is in the alpine zone. The arrival of winter will make the cable and soil form a whole. Once the ground is settled, it will be pulled at the bottom of the garden lamp base, and it will be burned at the base when there is much rain in summer.

4 The planning is improper

One is overload. With the continuous development of urban construction, garden lights continue to extend. When building new garden lights, it is usually connected to which circuit is close to the garden lights. In addition, the advertising industry has developed rapidly in recent years, and the advertising load is also connected to the garden lights, which makes the load of the garden lights too large, the cable overheating, the wire nose overheating, the insulation reduction, the ground short circuit and other conditions. On the other hand, the light pole planning only thinks about its own condition, ignoring the space of the cable head. The cable head is wrapped well in the future, most of them can not even close the door, sometimes the cable length is not good, and the joint manufacturing does not fit the request, which is also the element of the fault.

Three, protection measures

1. Strengthen the training of repair personnel

On the one hand, urban garden lights are closely related to people’s lives, and its operation directly affects the image of the Party and the government. It is necessary to improve the knowledge of garden lights repair operation and enhance the sense of responsibility through teaching. On the other hand, with the acceleration of the technological progress of urban garden lights and the extensive application of new technologies, repairmen are required to constantly update their professional knowledge and adapt to the operation requirements.

2. Accelerate the update of repair equipment

With the expansion of the city, the addition of the number of garden lights and service areas, the amount of repair personnel has been greatly increased. Without the addition of personnel, it is necessary to constantly improve and update the repair equipment to improve the operation efficiency.

3. Implement repair target responsibility system

On the basis of demarcating the handling area of courtyard lights, the repair responsibility system should be implemented layer by layer to determine the personnel, posts and responsibilities. Regular inspection and repair should be done, and the responsibilities should be found where there are problems.

4. Strengthen legal investigation

On the one hand, accelerate the formulation of normative documents for the management of garden lights, to create conditions for the management of the law; On the other hand, the joint urban management department intensified the law on yard lights, seriously investigated and dealt with the practice of damaging yard lights and equipment to ensure the normal operation of yard lights and equipment.

maintenance

1. Do not hang items on the lamp, such as drying quilts.

2, frequent switching, will greatly reduce its service life, so the use of lamps and lanterns to reduce the switch;

3. When the lampshade is found skewed in use or cleaning, it should be proofread accordingly to adhere to the beauty;

4. When adjusting the lamp shade, pay attention to prevent the tripod support in the lamp from reflecting the shadow when the light is on;

5. According to the light source parameters provided by the sign, replace the aging lamp tube in time. When it is found that the lamp tube is red at both ends, the lamp tube is black or there is black shadow, and the lamp tube is not bright, the lamp tube should be replaced in time to prevent the ballast from burning out and other unsafe scenes.

clean

1, the scene of courtyard lighting is usually more dust, cleaning with wet cloth to scrub, action adhere to the same direction, do not rub back and forth, the intensity should be moderate, especially for the chandelier, wall lamp to be gentle.

2, cleaning the interior of the lighting, cleaning the bulb, the first to turn off the light, scrubbing can be removed separately from the bulb scrub. If cleaning is done directly on the lamp, do not rotate the bulb clockwise to prevent the lamp cap from being too tight and peeling off.
