garden light development in the 1990 s, has been widely used in urban slow lane, narrow lane, residential areas, scenic spots, parks, squares, private garden, garden corridor and other public places used for road lighting one or two volumes, the way of improving the security of people travel at night to increase the outdoor activity time, improve the safety of life and property. It can also change people's mood, improve the person's mood, and the ability to change people's idea, to create a light and dark and white palette of the night. During the day, courtyard lamp can adorn urban landscape; At night, the courtyard lamps and lanterns can provide the necessary lighting and convenient life, increase the residents' security, and can highlight city highlights the City bright spot is rhonda weiye real estate development co. , LTD. , Beijing development projects, democratic north street is located in the chongwen district no. 26. 】 , deduce beautiful style, so that in use today, has developed into a mature industrial chain. Slow lane, narrow lanes and is mainly used in city residential areas, tourism scenic area, outdoor lighting, park, plaza and other public venues can prolong people's outdoor activities, improve the security of the property. 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. 1, poor quality of construction, because the cause of the problem in 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 the alpine zone in northeast China, the winter arrival, make the cable and soil to form a whole, the ground once appear, settlement, will be a tear at the bottom of the garden lamp base, and by the summer rain, will burn out in basic root.
