As the ornament of the space environment, the courtyard lamp can be said to be very beautiful. The day as a simple and unique ornament, at night with its light to create a beautiful night scene. But if we do not pay attention to some details when using, it is easy to cause the courtyard lights to have problems.

There are two kinds of common faults in courtyard lamps: one is high resistance fault, the other is low resistance fault. The so-called high resistance Fault, that is, the cable is burnt, the meter measurement resistance is larger, or interphase or to appear insulation decline, but there is a certain resistance; the so-called low resistance Fault, that is, the wire short or to the ground completely short, the current increase, transmission occurrence tripping phenomenon. These two kinds of faults and their frequent occurrence pose a threat to the normal use of the courtyard lights. Therefore, we must pay attention to the reasons and countermeasures.

Main reason of courtyard lamp malfunction

1. Poor construction quality
Because the construction quality caused by the fault accounted for a larger proportion. Main performance: First, the depth of the cable trench is not enough, the sand-covered brick is not carried out according to the standard construction; second, the production and installation of the aisle pipe does not meet the requirements, the two sides did not make the mouth of a cough, the third is the laying of cable on the ground dragged away; four is the basis of the embedded pipe not according to the standard construction, mainly embedded tube is meticulous, coupled with a certain curvature, It is very difficult to wear cable, at the bottom of the base there is a "dead bend" situation; Five is the line nose crimping and insulation wrap thickness is not enough, after a long time running will be short circuit

2. Material does not pass through
From the failure situation in recent years, the low quality of materials also has a great deal of factors. The main performance is: wire containing less aluminum, the wire is relatively hard, thin insulation layer. This situation has been more prevalent in recent years.

3. The quality of supporting works is not perfect
Courtyard Light cables are generally laid on the sidewalk. The pavement construction quality is poor, the ground sinks, the cable force deformation, resulting in cable armored. Especially in the Northeast region in the cold zone, the arrival of winter, so that the cable and soil form a whole, once the ground subsidence, will be in the base of the courtyard lamp is pulled, and the summer rain, will be in the base of the root burn.

4. Unreasonable design
On the one hand, the city courtyard lamp is closely related to the citizen's life, its operation influence the party and the government's image directly, must through the education enhances the maintenance personnel to the courtyard lamp maintenance work understanding, enhances the sense of responsibility. On the other hand, with the speeding up of the city courtyard lamp, the application of the new technology will require the maintenance personnel to renew the professional knowledge and adapt to the work.

Protection measures

1. Strengthening training for maintenance personnel
On the one hand, the city courtyard lamp is closely related to the citizen's life, its operation influence the party and the government's image directly, must through the education enhances the maintenance personnel to the courtyard lamp maintenance work understanding, enhances the sense of responsibility. On the other hand, with the speeding up of the city courtyard lamp, the application of the new technology will require the maintenance personnel to renew the professional knowledge and adapt to the work.

2. Expediting the renovation of maintenance equipment
The expansion of the city, the number of courtyard lights and the increase in service area, so that the workload of maintenance staff increased, in the case of no increase in personnel, it is necessary to continuously improve and update the maintenance equipment, improve work efficiency.

3. Implementation of maintenance target responsibility system
On the basis of the management area of the garden lamp, the implementation of the maintenance responsibility system is based on the fixed person, position and responsibility, to do regular patrol, regular maintenance, and find out who is responsible for the problem.

4. Strengthening law enforcement and investigation
On the one hand, speeding up the establishment of normative documents in the management of garden lights, to create conditions for administration according to law; On the other hand, the joint urban Management departments to increase the enforcement of courtyard lights, serious investigation and destruction of courtyard lights facilities, to ensure that the courtyard lights facilities normal operation.
