热压敏电阻:寿命结束阶段也能保护电力仪表
电力仪表很容易受到输入瞬变以及因雷击事件或电能质量扰动产生的浪涌的影响。在程度上可高达30kV 的这些瞬变取决于多种因素,包括地理位置、在附近连接的负载的类型等等。MOV是用于防止这些浪涌的主要器件。要求的浪涌抗扰度水平决定了MOV的额定值和尺寸。对于基本的2KV-4KV浪涌保护,14mm的MOV可能就够了。然而,对于30kV的保护级别,可能需要更大尺寸的32mm或34mm MOV。
因为电力仪表是使用寿命有限的无源器件,MOV存在与其使用寿命结束阶段相关的一些固有的问题。例如,一旦寿命终结,它们可能会对自身造成损坏并对它们的电子电路构成威胁。MOV在失效之前只能承受那么多次浪涌冲击,而且这种浪涌冲击承受能力取决于MOV圆盘尺寸和MOV设计用以吸纳的浪涌的等级。所以,在选择MOV时,除了要考虑所需的峰值浪涌抗扰度,考虑系统的预期寿命也同样重要。
图1:LITTELFUSE TMOV系列
举个例子,假设一个系统的预期寿命为五年,并且需要6V的保护。即使一只20mm的MOV能够满足6kV/3kA 15次冲击的标准,然而为了在仪表整个寿命周期内提供承受更多浪涌冲击的能力,将会使用25mm或更大尺寸的MOV。为确保系统能够达到其期望寿命,需要对所用的MOV进行足够的降额。
一些较新的规范同样要求针对寿命结束时的失效对MOV进行保护。对于这些应用,使用热保护的MOV(TMOV)图2以在其使用期内继续为电路提供保护。一旦它们达到寿命结束阶段,它们会将自己从电路中断开以防止灾难性的破坏。TMOV也可以具有指示功能,以提醒仪表保护器出现故障并且需要更换。
图2:TMOV和iTMOV电路保护
在快速上升的瞬变也可能会损坏供电部分的设计中,瞬态电压抑制(TVS)二极管通常与MOV结合使用。这些器件会钳制快速上升的瞬变而前端MOV会吸收这些瞬变中大部分高能量。
