When purchasing a voltage surge protector, the key points include:
√ Voltage level matching: The rated voltage of the surge protector should be higher than the actual working voltage to ensure that the device will not be damaged during normal operation.
√ Current capacity considerations: The maximum discharge current and nominal discharge current of the surge protector should be greater than the maximum surge current of the device to ensure normal operation during a surge event.
√ Fast response time: Choose a surge protector with a quick response time to protect the device in time.
Detailed explanation of each key point:
√ Voltage level matching:
The rated voltage of the surge protector should be higher than the actual working voltage to ensure that the device will not be damaged by overvoltage during normal operation. For example, if the working voltage of the device is 220V, the rated voltage of the selected surge protector should be higher than 220V, usually 240V or higher.
√ Current capacity considerations:
The maximum discharge current (Imax) and the nominal discharge current (In) are important parameters for evaluating the surge protector’s ability to withstand surge current. When selecting a surge protector, its maximum discharge current and nominal discharge current should be greater than the maximum surge current of the device to ensure normal operation during a surge event. For example, if the maximum surge current of the device is 40kA, then the maximum discharge current of the selected surge protector should be greater than 40kA.
√ Fast response time:
The response time refers to the speed at which the surge protector detects and responds to overvoltage. Selecting a surge protector with a fast response time can ensure that the device is protected when a surge event occurs. The faster the response time, the better the protection effect.
√ Other considerations when purchasing:
Installation location and protection object: Depending on the installation location and protection object, surge protectors are divided into primary, secondary, and tertiary levels. The primary surge protector is installed outside the building to protect against surge overvoltages caused by lightning; the secondary surge protector is installed inside the building to protect against surge overvoltages caused by residual surges from lightning and switching operations; the tertiary surge protector is installed near the power socket of the electronic equipment to protect against local surge overvoltages.
Technical parameter selection: Technical parameters such as current capacity, maximum discharge current, and residual voltage value must be selected according to the specific application scenario. For example, the current capacity of the power system surge protector should be greater than 10kA, the maximum discharge current should be greater than 50kA, and the residual voltage value should be less than 2.5kV.
Through the above tips and precautions, you can better choose the appropriate voltage surge protector to ensure the safe and stable operation of the equipment.
