【技术】探讨压敏电阻的作用以及经常发生烧毁的原因
说起压敏电阻,相信很多人都不陌生,然而压敏电阻在电路中是怎么烧坏的呢?也许就不太清楚了,优恩半导体将在本文介绍压敏电阻的作用以及经常发生烧毁的原因。
压敏电阻是在一定电流电压范围内电阻值随电压而变,也可以说是电阻值对电压敏感的阻器。压敏电阻是按用途来命名,称为突波吸引器,或电冲击(浪涌)抑制器(吸收器)。
图 1 实物图
压敏电阻器在电路各简单来说有三个作用:
●过电压保护;
●耐雷击要求;
●安规测试需要。
压敏电阻在电路中的电压保护作用,一般可以与保险丝配合作雷击或其它的过压保护。通常用于防雷;过电压发生时,压敏电阻会被击穿,呈现短路状态,从而将其两端电压钳位在较低水平,同时短路引起的过流将烧毁前方保险管或迫使空气开关跳闸,从而强制切断电源。一般来说它损坏后对其它元件影响不大。只检查与之相连的电路元件即可。如果是击穿性损坏,,那将会把保险丝烧断。
在正常电压下工作时(电路中的电压小于压敏电阻的额定电压)压敏电阻的阻值无限大,在电路中不起作用。当电路中的电压超过压敏电压时,压敏电阻的阻值会急速下降,起到分流限压作用,同是电路中的保险丝会熔断,起到保护作用。如果电路中没有保险丝,压敏电阻会发生爆裂,损坏失效,失去保护作用,导致后面的电路烧毁。
压敏电阻经常发生烧毁原因:
●老化失效,表现为漏电流增大,压敏电压显著下降,直至为零;
老化失效是指电阻体的低阻线性化逐步加剧,漏电流恶性增加且集中流入薄弱点,薄弱点材料融化,形成1kΩ左右的短路孔后,电源继续推动一个较大的电流灌入短路点,形成高热而起火。这种事故通常可以通过一个与压敏电阻串联的热熔接点来避免。而暂态过电压破坏是指较强的暂态过电压使电阻体穿孔,导致更大的电流而高热起火。整个过程在较短时间内发生,以至电阻体上设置的热熔接点来不及熔断。
●暂态过电压破坏。
●过压保护的次数;
●周围工作温度;
●压敏电阻有无受挤压;
●是否通过品质认证;
●浪涌能量太大,超出吸收功率;
●耐压不够;
●电流与浪涌过大等等。
压敏电阻的使用安全性一直是一个需要重视的问题。因压敏电阻器广泛地应用在家用电器及其它电子产品中,起过电压保护、防雷、抑制浪涌电流、吸收尖峰脉冲、限幅、高压灭弧、消噪、保护半导体元器件等作用。建议选用优质的压敏电阻器。

基于硕凯压敏电阻14D561K的IGBT快速开关电路,在浪涌抗干扰度试验中通过4级,且试验电压提高10%
本试验选用压敏电阻14D561K:击穿电压:504V-616V;通流量IPP高达4500A;位电压最大值 925V(50A);工作温度:-55 至+125°C;具有通流量大、残压低、响应时间快等特点。当干扰电压达到一定值时,就会把两端的电压钳位住,从而保护IGBT不被击穿

介绍压敏电阻的特点及应用
压敏电阻(Varistor)是一种电压敏感型电阻元件,当施加的电压超过其额定值时,电阻迅速减小,从而起到过电压保护作用。它广泛应用于电子设备中,防止电路因瞬态电压、浪涌电流或雷击等引发的损坏。本文中优恩半导体来为大家介绍压敏电阻的特点及应用,希望对各位工程师朋友有所帮助。

赛尔特(SETsafe丨SETfuse)TFMOV 热保护型压敏电阻(熔断合金型)选型指南
描述- 热保护型压敏电阻-熔断合金型Thermal Fuse & MOV(TFMOV)是一种带热保护的压敏电阻。该产品具有有压敏电阻(MOV)的所有特性,同时还带有热保护的功能。MOV存在因为长期工作自然劣化、或异常的浪涌导致的劣化两种情况的劣化。当浪涌来临时,劣化后的MOV漏电流持续增大,会导致MOV表面温度持续升高,并有着火可能。这时TFMOV中的温度保险丝(易熔合金)感温到这个异常温度而动作(熔断),将MOV从主回路中脱离从而保护整个电路,以及MOV本身不会持续发热,着火的现象。
