When using electricity in summer, you must pay attention to preventing problems before they occur. Being alert to using electricity can help you keep away from potential safety hazards. In summer, when the temperature is high, various household appliances are used too frequently, which makes the electrical circuit operate normally under overload, which is easy to cause electrical fire accidents. Therefore, multiple high-power appliances should not be used at the same time as much as possible. Wires should not be connected and pulled randomly. Multiple appliances should not use the same socket to avoid short circuit.
The surge protection extension line can avoid this kind of accident. The surge protection extension line has three main characteristics in design. First, continuous operation voltage, Uc value, 385V for normal environment. The other is the voltage protection level, Up value, which is selected according to 80% of the impulse voltage withstand value of the protected electrical equipment. The third is the maximum discharge current, whose value is related to the waveform of the impulse current and the object protected by SPD.
In addition, the section and number of conductors connecting SPD connection phase line to grounding terminal, and the number of SPDs used for different grounding forms of power distribution system are also different. SPD protective devices shall be provided by the manufacturer. The surge protection extension line can better protect the surge.
