1. This series of single-phase power supply arrester adopts dark all-metal casing, which is good in sealing, safe and reliable.
2. This series of single-phase power supply arresters are connected in parallel with the protected equipment; do not disassemble this series of products.
3. The user should correctly connect the wiring mark on the arrester. The grounding wire should be insulated yellow-green copper wire with a cross-sectional area of ​​not less than 25mm.
Ground wire length is as short as possible to reduce grounding resistance.
4. This series of products are equipped with installation accessories when they leave the factory. Users can install and wire according to the actual situation. After checking whether there is no connection, they can be powered on and put into operation.
5. Regularly check the operation of the power supply arrester:
When the lightning arrester is normal, the work indicator (green light) is on. When the deterioration indicator (red) on the lightning arrester is on, it indicates that the important components inside the lightning arrester are invalid, please replace it immediately. 6. During the use of the lightning protection box, periodically check and check the working status of the indicator light: the green indicator light is the work indicator, the lightning protection box works normally; the red indicator light does not light when it works normally, when the lightning protection box fails, the red indicator When the light is on, it should be repaired or replaced in time.
7. The lightning counter of the power lightning protection box has a counting range of 0~99 times, the counting action current is not less than 5KA; when it is energized, it is displayed as 00 times. When the power is off, it is no longer displayed. You can press the “Reading†button to display the number of lightning strikes. . The counter clear button is provided at the upper end of the lightning protection box, and the counter can be cleared at any time after viewing;
8. The grounding resistance is not more than 4Ω.
9. Non-professionals should not disassemble
The cabinet is made of high quality steel, which is flame retardant and anticorrosive.
l Single-phase integrated power supply lightning protection box adopts working status indication and lightning strike counting to provide remote signaling, sound and light alarm
l Single-phase integrated power supply lightning protection box adopts pressure-sensitive series gas discharge tube to completely eliminate leakage current and has higher safety performance
ã€working principle】
The single-phase integrated power lightning protection box is when the lightning-inducing lightning-inducing component enters the power transmission line, the lightning protection component of the lightning arrester exhibits a low-resistance state in a response speed of nanosecond (100 ns), rapidly discharging the lightning current to the earth, and The overvoltage caused by lightning current is limited to the range of withstand voltage that the protected equipment is allowed to withstand to ensure safe operation of the equipment and protect the equipment from damage.
