There are mainly two kinds of charging piles, AC surge protection device and DC spd, in the SPD electric vehicle charging station dedicated to charging piles. The charging piles all adopt integrated intelligent systems, and are equipped with microprocessors and high-precision integrated circuits inside. The electric piles are located outdoors, so they are vulnerable to the impact of induced lightning surges. If they are not protected, they are easily damaged by lightning strikes.

The charging piles will be damaged in the slightest, and the charging piles will be damaged in severe cases. The consequences will be more serious. And later maintenance is also very troublesome. The charging pile is mainly composed of two parts: AC-DC power conversion and DC output control. According to the combination form, it can be divided into two types: integrated charging pile and split charging pile; Integrated charging pile: refers to the combination of AC and DC power conversion and DC output control, which is suitable for outdoor installation.

Split charging pile: refers to the form in which the AC-DC power conversion and DC output control are separated into two monomers, and they are connected by cables to form a complete charging machine. Under normal circumstances, the surge protector is in high-impedance state, the leakage current is extremely low, and does not affect the normal operation of the charging pile (station). When there is a surge overvoltage, the surge protector will be turned on immediately to limit the overvoltage amplitude within the safe working range of the equipment, and at the same time release the surge energy into the ground to ensure the normal operation of the charging system.

Product features: 1. Reliable thermal tripping protection device; 2. Unique short circuit and overcurrent tripping function; 3. Visual status indication window: green/transparent (normal), red (fault) working status at a glance; 4. Response The time is fast, and the action is within nanoseconds; 5. The remote signaling contact is optional; 6. The leakage current is almost zero and the service life is long.
