2. 概述
INTRODUCTION
压敏电阻是一种具有在一定的电压条件下支持电流急速流出的电压-电流特性的产品。
A varistor has the volt-ampere characteristics in which current suddenly starts to flow through the device at a certain
voltage.
压敏电阻的作用：保护在电子线路中的电子元器件免受过电压的影响。如下图所示，压敏电阻并联在电
路中起保护作用。当有脉冲(脉冲电流Is：由脉冲电压Vs和阻抗Zs决定)施加在电路上时，脉冲电流（Is）
限制脉冲电压在压敏电阻的限制电压Vc之内。
The varistors are used to protect components in electronic and electric circuits from overvoltage. 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.

使用压敏电阻器时，压敏电阻器周围条件（设备设计中的材料、环境、电源条件、电路条件等）发生异常时，则可能引发火灾、
触电、烧伤、以及产品故障。
In case that a varistor is used, if an abnormality takes place because of peripheral conditions of the varistor(material, environments, power source
conditions, circuit conditions, etc. In equipment design), fire, electric shock, burn, or product failure may be occur.
下列内容为使用时的相关注意事项，请认真确认后再行使用。如对未及事项有疑议，请速与我公司担当部门联系。
The precautions for this product are described below; understand the content thoroughly before usage. 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
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.
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.
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.
线-地间使用
Use between line to ground
a) 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.
b) 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.
使用注意事项

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.),
c) 选定压敏电阻器时，须按照表1的标准产品型号
Select a varistor recommended in table 1.
① 线间使用

说明
Notices
用于可靠性要求极高的设备（航空航天设备、医疗设备等）时，请事先至本公司咨询使用型号和保护措施等相关事宜。
In cases that the varistor is used in equipment (aerospace equipment, medical equipment, etc) requiring extremely high reliability, ask us for a selection of
part no., and protection coordination, etc in advance.
若未按照产品规格书记载事项进行操作，并由此导致出现异常时，本公司不负任何责任。
Note that we do not take any responsibility for faults and abnormalities resulting from the use not in conformity with the contents of entries in the delivery
specification.
出现使用电路电压的异常上升、超高浪涌的侵入等不可预期因素时，可能导致压敏电阻器起火。为防止延烧到使用设备上，外部
结构材料需使用阻燃材料进行多重保护。
There is a possibility that the varistor will unexpectedly cause smoke or ignite because of an abnormal rise of the circuit voltage and invasion of excessive
surge. To prevent that accident from spreading over the equipment and not to expand the damage, use multiplex protection such as the adoption of frameretardant materials for housing parts and structural parts.
