When the transient overvoltage occurs in the power supply line, the SPD will be fused through, which will cause the power supply trip and accident. After installing SCB backup protector, when SPD transient overvoltage short circuit occurs, the circuit can be quickly disconnected to avoid accidents caused by SPD penetration. When the lightning current passes through, SCB backup protector can effectively avoid false tripping, make the surge protector always in an effective state, and ensure the safety of power consumption. The backup protector plays a very important role, but it depends on whether your products are of good quality. Good quality will play a great role. You should use the backup protector for lightning protection. The direct effect of the backup protector produced by LEIHAO Lightning Protection Company and SPD is that the SPD backup protector will not be broken under heavy lightning impact; After SPD breaks down, the small power frequency current flow is cut off quickly to ensure the safety of power grid and power consumption. When transient overvoltage occurs in the power supply line, the SPD is turned on, which will lead to power trip and accidents. After installing SCB backup protector, the circuit can be quickly disconnected when SPD is short-circuited by transient overvoltage, thus avoiding accidents caused by SPD breakdown. When lightning passes through, the SCB backup protector can effectively avoid false tripping, so that the surge protector is always in an effective state, ensuring the safety of power consumption. According to relevant standards (GB188021 and GB50057), the front end of SPD circuit must be connected in series with the over-current protection device. The existing universal current protection devices on the market are mainly used to protect the fuses or circuit breakers of the back-end electrical equipment. They can not effectively cooperate with SPD, and it is difficult to achieve lightning protection function. In serious cases, it may even cause a fire.
