As shown in following figure, a varistor is inserted in parallel with a circuit to be protected. When a pulse is applied to the circuit, pulse current Is, which is determined by pulse voltage Vs and pulse impedance Zs, flows to limit the pulse voltage to the varistor limit voltage Vc. 压敏电阻器对脉冲的吸收 PULSE ABSORPTION BY VARISTOR 相互的关系可以用下面的公式来解释： The relation can be expressed by the equations as follows: Vs=Is×Zs+Vc ∴ Vc=Vs-Is× Zs 因为Vs远远大于Vc，脉冲电流Is可以用以下公式求得 The pulse current Is are easily obtained by the following equation because of Vs much larger than Vc. Is≈Vs÷ Zs 所以，由于可承受电压大于最大的限定电压，电路可以长时间的免于脉冲电压的损坏。 Thus, the circuit can be protected from being damaged by pulse voltages as long as it has withstand voltage larger than the maximum limit voltage. 由于吸收异常电压和电流脉冲的特性，压敏电阻可非常高效的保护电子器件。 Owing to the characteristic, the varistors are extremely effective as protecting devices of electronic and electric equipment by absorption of abnormal voltages and lightening pulses. 编号DOC NO.: 压敏电阻器规格承认书 APPROVAL SPECIFICATION FOR VARISTORS (ZnO) DEC-SA-WI007 版本REV.: A/4 日期DATE: 2020/8/15 页码PAGE: 5 / 15 TÜV SÜD回复我公司证书号码变更原因(截图)： TÜV SÜD reply to our certificate number reason for change (screenshot): 3. 基本特性 GENERAL CHARACTERISTIC ■ 符合RoHS 2.0、REACH及无卤 Comply with rohs 2.0, reach, halogen-free available. ■ 安规认证 Safety certification 认证机构 CERTIFICATE AUTHORITY 认证标准 APPROVAL STANDARD 证书编号 CERTIFICATE NO.

For more questions, contact us. 严格遵守事项 Precautions to be strictly observed 额定性能确认 Confirmation of performance ratings 请遵守压敏电阻器的最大连续工作电压，耐冲击电流、最大能量耐量、浪涌寿命、额定功率和操作温度范围等额定性能的规定， 在规定范围内使用。 Use the varistor within its rated range of performance such as the maximum continuous operating voltage, withstanding surge current, maximum energy, impulse life, rated power and operating temperature range. 超出规定范围使用，则会造成压敏电阻器性能劣化，破坏元件，严重可引起压敏电阻器冒烟或起火。 If used outside the range, the varistor can be degrade and have element fracture, which may result in smoking and ignition. 为避免意外现象发生，请采用如下对策 To avoid accidents due to unexpected phenomena, take the following measures 1) 压敏电阻器受损时 ，可能出现破碎飞散，因此要对集成产品加保护盖或外盒。 In the event of fracture of the varistor, its pieces may scatter; hence, put the case or cover of the set product in place. 2) 请勿安装在可燃物品（塑料电线、树脂合成物等）附近。若无法避免，请使用不燃性保护外壳。 Do not install the varistor near combustible substances (polyvinyl chloride wires, resin moldings, etc.). If it’s difficult to do, install a nonflammable cover. 3) 线间使用 Across-the-line use 在线间使用时，将保险丝与压敏电阻器串联。 When the varistor is used across a line, put a current fuse in series with the varistor. 4) 线-地间使用 Use between line to ground a) b) 在线-地间使用时，压敏电阻器短路时会产生接地电阻，电流保险丝不会熔断，可能引起压敏电阻器外涂层树脂冒烟或起火。 If the case that the varistor is used between a line to the ground, the short circuit of the varistor may not blow the current fuse because of grounding resistance, which may cause smoking and ignition of the varistors exterior resin. 为避免上述情况，请在电源端安装漏电断路器。如无漏电断路器，则需将电流保险丝与温度保险丝串联使用。 As the measure against it, install an earth leakage breaker on the power supply side of the varistor position. If no earth leakage breaker is installed, use a thermal fuse together with a current fuse in series. 在带电部件与金属部件之间使用压敏电阻器时，压敏电阻器短路时有触电危险，故请将金属部件接地或勿与人体接触。 If the case that the varistor is used between a live parts to metal case, an electric shock may develop at a shortcircuit of the varistor; hence, ground the metal case to the ground or keep it from the human body. 7.2. 使用注意事项 Application notes 7.2.1. 注意下列事项，可能导致压敏电阻器寿命缩短或引发故障 Pay attention to the following items to avoid the shortened life and failure of the varistor. 1) 电路条件 Circuit conditions a) 选定的压敏电阻器的电压最大值在最大连续工作电压值之上。 Select a varistor of which the maximum voltage including fluctuations in source voltage allows for the maximum permissible circuit voltage. b) 短间隔性地施加浪涌时（施加抗干扰模拟试验电压时），不可超过压敏电阻器的额定功率。 In cases that surges are intermittently applied at short intervals (for example, in case that the voltage of the noise simulator test is implemented etc.), do not let them exceed the varistors rated power. 选定压敏电阻器时，须按照表1的标准产品型号 c) Select a varistor recommended in table 1. ① 线间使用 Across-the-line use 单相三线式连线时单独配线负荷导致负荷不平衡、电压线和中性线短路、中性线欠损、容量性负荷情况下开闭时的共振 等，将导致电源电压的上升，可能使用表1中标有＊的产品型号。 If possible, use a part no.
