as the ornament with space environment, courtyard lamp is very beautiful. As a simple unique ornaments during the day, use it again in the evening light to create a beautiful at night. But if we do not pay attention to in the use of some details, it is easy to cause problems garden light. Garden light common fault has two kinds: one kind is high impedance fault' Failure to present a high impedance earth fault. 】 ; Another kind is low resistance fault. So-called high impedance fault, namely cable was burn out, the instrument measuring the resistance is bigger, or of a drop in insulation or alternate with, but there is a certain resistance; The so-called low resistance fault, that is, quite short wire short or over the ground, current, power trip. These two kinds of fault and its frequent use of garden light normal pose a threat. Therefore, must be full attention, find the reason and countermeasures. The main reason for the garden light failure 1. Poor quality of construction for construction quality caused by the fault for a larger proportion. Main performance: one is the cable trench 【 In cable trench is to change electric power or telecommunications cable laying and facilities of the underground pipeline, palisade structure is also been laying cable facilities, such as rectangle, circle, arched pipeline structure. 】 Depth is not enough, sanding brick construction according to the standard; 2 it is aisle pipe production and installation does not conform to the requirements of both ends not made syndromes according to the standard beep mouth; Three is cable when the shop is dragging on the ground; Four is not in accordance with the requirements of standard construction is the foundation of embedded pipe, refined classification is mainly embedded pipe, coupled with a certain amount, difficult in cable, in the base at the bottom of the 'dead turn'; Five is the line nose and the thickness of insulation wrapped pressure is not enough, after a long run would interphase short circuit 2. Material don't pass it from years of treatment failure, material quality is low and there is a big factor. Main show is: less wire containing aluminum, lead is hard, thin insulating layer. This situation is more common in recent years. 3. Form a complete set of engineering quality is not good garden light cable generally spread on the sidewalk. The pavement construction quality is poor, ground subsidence, the cable force deformation, cable sheathing. Especially in northeast China Northeast China, is a geographical cultural regions and economic regions of China, is not administrative region; The word 'northeast', originally found in the rites, fang '. 】 In the alpine zone, winter arrived, the cable and the soil to form a whole, once appear subsidence, ground will be a tear at the bottom of the garden light foundation, and the summer rainfall, will burn out in basic root. 4. Design is not reasonable on the one hand, city garden light is closely related to life, it is good or bad directly affect the image of the party and the government, must through the education to improve the knowledge of maintenance personnel maintenance work of garden light, enhance the sense of responsibility. On the other hand, with the speeding up of city garden light science and technology progress, the utilization of new technology, need to maintenance personnel for repair professional knowledge update, meet the needs of work.
