Outdoor garden lights often fail

There are two common faults: one is a high impedance fault; the other is a low impedance failure. The so-called high-resistance fault, that is, the cable is blown, the meter measures is large, or the two-phase or ground is insulated, but there is a certain resistance value; the so-called low-resistance fault, that is, the wire is short or completely short, so that the current increases, the power transmission has a trip phenomenon. These two types of failures and their frequent use of the garden lamps have pose a threat. Therefore, it is necessary to pay full attention to the causes and countermeasures.

Problem

1. Poor construction quality

The scale proportion caused by construction quality is large. Main performance: First, the cable depth is not enough, the package sand bricks did not construct according to standards; the second is that the channel tube production is not required, and the two ends are not produced according to standards; the third is that when the fourth pre-buried paved the cable tube According to the standard requirements, it is mainly because the Pre-Buried pipe is too thin, plus a certain degree of bending, it is difficult to wear a cable, and there is a foundation of the "dead bend"; the head crimping and insulation cover are not thick enough, and after a long period of operation, the phrases are short-circuited.

2. The material did not fall off

From the perspective of the failure of processing in recent years, the quality of the material is also low. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulating layer is thin. In recent years, this situation is more common.

3. The quality of support project is not too difficult

Garden lighting cables are generally laid on the sidewalk. The road is poor, the ground is sailed, and the cable is deformed, resulting in cable armor. In particular, the northeast of my country is in a very cold zone, and the arrival of winter has enabled the cable to form a whole. Once the ground is trap, it will tighten the bottom of the garden. In the summer, the rain is too much, it will be blown at the base.

4. This design is unreasonable

On the one hand, it overloads. With the continuous development of urban construction, the landscape lights are also extended. When the lanterns have been built, which loop light is close to, which loop receives, in recent years, the advertising industry has developed rapidly, and the advertising load is also connected to the courtyard. For the lamp, the park is too large, the cable is overheating, the line nose is overheating, the insulation is lowered, the ground short circuit; on the other hand, the design of the lamp post "only considers the conditions, ignoring the space cable header, the cable header, most of the doors are not closed, sometimes, the length of the cable is insufficient, and the joint production cannot meet the needs, this is the reason for failure.

Landscape lighting protection

1. Strengthen training for maintenance personnel

On the one hand, urban landscape lights are closely related to the people 's lives. Its operation directly affects the party's image and the government. It is necessary to raise the awareness of the maintenance of landscapes and enhance the sense of responsibility. On the other hand, with the accelerated advancement of urban landscape lighting technology, the wide use of new technology, requires maintenance personnel to continue to update maintenance expertise to meet the needs of work.

2. Accelerate the maintenance of equipment

The expansion of the city, the increase in the number of garden lights and the area of service, greatly increasing the workload of the maintenance personnel. In the absence of increasing number of people, 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 delineation of the landscape light management area, the maintenance responsibility system at all levels, the implementation personnel is fixed, and the responsibility is fixed. It is necessary to conduct regular inspections, regular maintenance, and find out the responsibility of the problem.

4. Strengthen law enforcement investigation

On the one hand, accelerate the development of garden lamp management normative documents, and manage conditions according to law; on the other hand, the urban management joint department will increase the garden law enforcement, and seriously investigate and deal with the behavior of the gardening facilities, and ensure the normal operation of the gardening facilities.
