Street Light Manufacturers

Street light involve lighting technology and are suitable for street lights. The street light purpose is to design a high-efficiency electronic energy-saving street lamp with long life, low power consumption, high power factor and small current harmonic content. The high-efficiency electronic energy-saving street lights comprises sequentially connected grid high-voltage discharge branches R1, C1, rectifier bridges D1-D4, power factor correction branches C2, D5, D6, high-intermediate frequency glitch filter branches L1, L3, high-frequency oscillation circuit BG1-BG2, start branch L2, C7 and lamp tube T; can save 80% energy than previous street lamps; harmonic content THD <25%, extending lamp life can reach 3-4 times.

3. Practice of connecting the vertical line to the power supply side
4. If the standing line is more than four meters, a support should be added in the middle to fix it, and the insulated twisted wire of no less than 7/1.0 shall be used, and the single cross binding method in the standard issued by the connecting office shall be adopted.
5. When the main line and the vertical line are different metals, the interphase tie wire should be used as the transition joint bow. The longest length of this bow is no more than 100 mm.
6. The black leather wire should have black tie wire at the insulation support to turn around and refuse to use this wire for winding.
7. Plastic pipes should be added to the iron pipe or the gray pole hole of the power cord. The length of the pipe should not be less than 200 mm.
8. There can be at most one joint in the volley section of the vertical line. The joint is wound 5-7 circles on both sides of the joint and covered with plastic cloth. Different specifications cannot be docked.
9. Penetrate the power cord inside the iron pipe and rod hole, and refuse to have a connector.
10. The vertical line refuses to pass through between the high-voltage lines.

installation
Process flow
Insulation test → street lamp installation → electrical equipment installation → test, pressure test → self-checking and acceptance of the electrical system, according to the sequence of civil construction, do a good job of concealing the cable pre-buried pipe and prevent clogging of the pre-buried pipe.
Construction method
1. Insulation test: use a shaker to remotely measure the insulation resistance between the line and the ground, check whether the cable is intact, and whether there is leakage. All the test values should meet the specifications. After the remote measurement is completed, the core wire should be discharged to the ground. The end of the cable should be sealed with rubber cloth and wrapped with rubber cloth.
2. Street lamp installation:
(1) The installation height (from the light source to the ground), elevation angle, and installation direction of street lamps at the same position should be consistent.
(2) The longitudinal center line of the lamp installation and the longitudinal center line of the lamp arm should be the same, the horizontal horizontal line of the lamp should be parallel to the ground, and there should be no skew after visual inspection after fastening.
(3) The lamp head is fixed firmly, the adjustable lamp head should be adjusted to the correct position according to the design, and the lamp head wiring should meet the regulations
(4) All kinds of nuts should be fastened, and gaskets and spring pads should be added.
3. Electrical equipment installation:
(1) After the materials arrive at the site, they will be inspected after unpacking.
(2) The center line of the moving contact and the static contact should be consistent, and the contacts should be in close contact.
(3) The switching contact of the auxiliary switch of the secondary circuit should be accurate and reliable.
(4) The mechanical blocking and electrical blocking actions should be accurate and reliable.
(5) The grounding system must be firm and reliable and meet the requirements of drawings and specifications.
4. Test and pressure test: The commissioning equipment, instruments and instruments must be inspected and qualified by the relevant units recognized by the state with measurement qualifications, and be used and kept by a dedicated person.
(1) The insulation test of the electrical circuit must be qualified, the impedance matching is appropriate, the wiring is correct, and the signs are clear and complete.
(2) The meter should be responsive, accurate in measurement, correct in zero position, indicating accuracy, variation, and recording accuracy in accordance with the requirements of the manual.
(3) After the installation is completed, check and confirm that it is correct before proceeding to itemized debugging.
