Solar led street lamp installation methods of road light

Light road bar size generally to be decided by the street lamp height, width is 8% of the lamp height; Buried depth is greater than or equal to 5 meters or buried depth is greater than or equal to 4 times of that of the base width bai referred to as the basis of the deep foundation; Buried in the deep of 0. Between 5 m ~ 5 m or buried depth is less than 4 times of the width of the foundation of the

 light road bar size generally to be decided by the street lamp height, width is 8% of the lamp height; Buried depth is greater than or equal to 5 meters width or depth is greater than or equal to the basic bai 【 Pinyin is 'bai' characters are: the white place lost thanks to hk parker tares bai break bai 庍 拝 & n. Four times referred to as the basis of the deep foundation; Buried in the deep of 0. Between 5 m ~ 5 m or buried depth is less than 4 times of the width of the base known as the basis of the shallow foundation. The foundation shall not shallow depth at 0. 5 meters. 1, the process flow: - street lamp device - electrical equipment insulation test device to test, test, self-check completion inspection and acceptance of electric system, according to the civil engineering construction order, ready to have cable trunking line pipe, brace for embedded pipe plugging operation at the same time. 2, the construction way: insulation test: with shaking table telemetry insulation resistance between line and ground, check whether the cable shape, with or without leakage, the test values shall be fitted specification requirements, telemetry, the discharge should be core over the ground, cable end use rubber cloth wrapped with tape after sealing. 3, road lamp installation: ( 1) Height, tongfang lighting device ( From the light source to the ground) For a common, elevation Angle and lighting direction. ( 2) Longitudinal centerline and longitudinal center line of arms, lamps and lanterns device should jointly, lamps and lanterns of lateral horizontal line should be parallel to the ground, after fastening visual should not tilt. ( 3) , lamp holder, fixation, adjustable lamp holder should be adjusted to the correct orientation, according to the planning in socket connection should fit the rules. ( 4) , all kinds of nut fastening, appropriate add washer and spring washer. 3, electrical equipment installation: ( 1) , materials to be present upon opening, after inspection qualified rear device can be used. ( 2) , dynamic contact, together with the static contact center should contact should touch closely. ( 3) The secondary circuit, auxiliary switch switch contacts should be accurate, touch. ( 4) , mechanical lock, electric locking action should be accurate and reliable. ( 5) , secure necessary solid grounding system and agree with the drawings and specification requirements. 4, experiment, testing, debugging equipment, instrument, appearance is necessary to qualify for the measurement of the world relevant units inspection qualified, and use, custody. ( 1) , the insulation of the electric circuit the experiment it is necessary to qualified, impedance matching, appropriate wiring is correct, mark clear completely. ( 2) , appearance should response sensitivity, measurement precision, zero is correct, accuracy, variation and record accuracy with specification requirements. ( 3) , installation after the completion of the inspection, admit and correct, before adjustment of the component. ( 4) , various disciplines, after the completion of debugging can be carried out system debugging, linkage debugging, commissioning. Above is the foundation of the road light depth standard requirements and installation methods, I believe you after looking at this article must have some idea.
