What brand of photovoltaic panels is good quality descending type high lamp structure

High lamp application is becoming more and more widely, many areas are set up to the light, and the lifting of light, especially the most, then lift is light, structure characteristics and principle of elevator? - - Characteristics - high lamp structure - Lift high lamp by lift lamp, lamp pole,



high lamp' Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 Is finding wider and wider application, many areas are set up to the light, and the lifting of light, especially the most, then lift is light, structure characteristics and principle of elevator?

- - Characteristics - high lamp structure -

lift high lamp by lift lamp, lamp pole, lifting mechanism, electric apparatus, etc. Lifting fixtures composed of mast and the bracket of lamps and lanterns, and equipped with a positioning device. Lifting frame is made of high qualified steel plate or steel welding form is diversiform, can adapt to all kinds of lighting requirements, there are mainly square, circle, polygon, etc. , can be designed according to the requirement of the user model. Light pole section for more ling conical rod splice, usually for 3 ~ 6 section, the section length is 7 ~ 10 m, overall taper 1:6 9, upper diagonal Φ 300 mm in diameter. High lamp light pole single section for the carbon steel plate fold into many ling cone, and USES the CO2 [ One of carbon dioxide, the chemical formula for CO2, carbon oxide, is a colorless, odorless gas under normal temperature, density is slightly larger than air, slightly soluble in water, and produce carbonic acid. 】 Gas shielded welding welding and become, section and internode without horizontal welding. Light pole and parts are all made of hot dip galvanized 【 Hot dip galvanized, 镀锌) Also called hot dipping zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. 】 Anticorrosive processing, light pole rectangle hole at the bottom of the lifting mechanism and electrical transmission device, the bar at the top of the fixed pulley block, trip switch, link device, the cover, the lightning rod Lightning, and lightning protection needle, is used to protect buildings, tall trees, etc to avoid lightning device. 】 And so on. Lifting system is composed of motor, worm gear and worm reducer, block and tackle, gear, coupling, drum, cable and so on, has the life freely, steady, safe and convenient operation, etc. Electrical part installed at the bottom of the light pole door, power use 380 v three-phase four-wire 【 Three-phase ac motor armature has three sets of coil, its connection with y connection and delta connection, generally USES the star connection method. 】 Introduced, and then to the electrical panels on the air switch into the terminal. The peak of a lightning rod, shaft is used as ground into ground, the grounding resistance is not more than 10 Ω. Lighting control standard is set to manual overtime control, can also according to user requirements into high lamp manufacturer line setup.

- - Light lifting - principle -

in elevating high lamp at the bottom of the rectangle in the inner chamber, in addition to the installation of electrical control system [ Electrical control system generally referred to as the secondary control circuit electric equipment, different devices have different control loops, and high voltage electrical equipment and control way of the low voltage electrical equipment is not the same. 】
