Common faults and maintenance methods of garden lights

December 13, 2022

The common faults of garden lights are divided into high-resistance faults and low-resistance faults. What is a high-resistance fault? What is a low-resistance fault? High-impedance fault, that is, the cable is blown, the resistance measured by the ammeter is large, or the insulation between phases or grounds drops, but there is a certain resistance value; low-resistance fault, that is, the wire is short-circuited or Dead short to ground, increased current flow, and tripped power transmission. These two types of failures and their frequent occurrence pose a threat to the normal use of garden lights. The following editor will explain to you the common faults and causes of garden lights.

The main reasons for the failure of garden lights:

1. The construction quality is poor, and the proportion of failures caused by the construction quality is very large.

The main reason:

1. The depth of the cable trench is not enough, and the sand-covered bricks are not built according to the standard;

2. The production and installation of the aisle pipes do not meet the requirements, and the two ends are not manufactured according to the standard;

3. When laying the cable, the fourth pre-embedded pipe is not constructed according to the standard requirements, mainly because the pre-embedded pipe is too thin, and with a certain curvature, it is difficult to wear the cable. There is a "dead bend" at the bottom of the foundation, and the wire head is pressed The contact and insulation packaging is not thick enough, and after a long period of operation, there is a short circuit between phases.

2. Poor material quality

Judging from the failures dealt with in recent years, the material quality is also very low.

The main reason: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is thin.

3. The quality of supporting projects is not up to standard

Garden light cables are usually laid on sidewalks. The construction quality of the sidewalk is poor, the ground sinks, and the cables are deformed by force, resulting in cable armor. Especially in the extremely cold area in Northeast China, the arrival of winter makes the cable and the soil form a whole. Once the ground recedes, it will be pulled at the bottom of the garden light foundation, and when there is too much rain in summer, it will burn at the root of the foundation. .

4. Unreasonable design

1. Overload operation. With the continuous development of urban construction, garden lights are also continuously extended. When new garden lights are often connected to whichever garden light is closest, they will be connected to which circuit, which will cause excessive load on the garden lights, overheating of cables, overheating of wire lugs, and reduction of insulation. short circuit to ground, etc.;

2. When designing the garden light pole, only the light pole itself is considered, and the space of the cable head is ignored. After the cable head is wrapped, most of them cannot even close the door. Sometimes the length of the cable is not enough, and the joints do not meet the requirements. factors causing failure.
