产品详情

江苏春晨电缆有限公司生产JFEM叁千伏电机引接线,

)额定击穿电压,它是指在指定反向击穿电流(常为lma)下的击穿电压,这于齐纳二极管额定击穿电压一般在2.9V~4.7V范围内,而雪崩二极管的额定击穿电压常在5.6V~200V范围内。

) the rated breakdown voltage, which refers to the breakdown voltage under the specified reverse breakdown current (usually LMA), is generally within the range of 2.9V to 4.7V, and the rated breakdown voltage of the avalanche diode is often within the range of 5.6V to 200V.

(2)最大箝位电压:它是指管子在通过规定波形的大电流时,其两端出现的最高电压。

(2) the maximum clamping voltage: it means the maximum voltage at the two ends of the tube when the current is regulated by the waveform.

(3)脉冲功率:它是指在规定的电流波形(如10/1000μs)下,管子两端的最大箝位电压与管子中电流等值之积。

(3) pulse power: it refers to the product of the maximum clamping voltage at the two ends of the pipe and the equivalent value of the current in the pipe under the specified current waveform (such as 10/1000 s).

(4)反向变位电压:它是指管子在反向泄漏区,其两端所能施加的最大电压,在此电压下管子不应击穿。此反向变位电压应明显高于被保护电子系统的最高运行电压峰值,也即不能在系统正常运行时处于弱导通状态。JFEM叁千伏电机引接线

(4) reverse position voltage: it means the maximum voltage exerted by both ends of the pipe in the reverse leakage area, and the tube should not puncture under this voltage. The voltage of the reverse position should be significantly higher than the peak value of the highest operating voltage of the protected electronic system, that is, it can not be in a weak conduction state when the system is running normally.

(5)最大泄漏电流:它是指在反向变位电压作用下,管子中流过的最大反向电流。

(5) the maximum leakage current: it refers to the maximum reverse current flowing through the pipe under the action of reverse displacement voltage.

(6)响应时间:10-11s

(6) response time: 10-11s

5.扼流线圈

5. choke coil

扼流线圈是一个以铁氧体为磁芯的共模干扰抑制器件,它由两个尺寸相同,匝数相同的线圈对称地绕制在同一个铁氧体环形磁芯上,形成一个四端器件,如图15e所示,要对于共模信号呈现出大电感具有抑制作用,而对于差模信号呈现出很小的漏电感几乎不起作用。扼流线圈使用在平衡线路中能有效地抑制共模干扰信号(如雷电干扰),而对线路正常传输的差模信号无影响。JFEM叁千伏电机引接线

The choke coil is a common mode interference suppression device with ferrite core as the core. It is made of two identical coils with the same size and turns on the same ferrite ring core to form a four terminal device. As shown in figure 15E, it is necessary to suppress the large electric sense of the common mode signal, and for the differential mode letter. The number shows a very small sense of electric leakage, which almost doesn't work. Choke coil can effectively suppress common mode interference signal (such as lightning interference) in the balanced circuit, but has no effect on the differential mode signal transmitted normally.

这种扼流线圈在制作时应满足以下要求:

The choke coil should meet the following requirements when making.

(1)绕制在线圈磁芯上的导线要相互绝缘,以保证在瞬时过电压作用下线圈的匝间不发生击穿短路。

(1) the conductor on the winding core is insulated with each other to ensure that there is no breakdown short-circuit between the turns of the coil under transient overvoltage.

(2)当线圈流过瞬时大电流时,磁芯不要出现饱和。

(2) when the coil flows through the instantaneous high current, the core should not be saturated.

(3)线圈中的磁芯应与线圈绝缘,以防止在瞬时过电压作用下两者之间发生击穿。

(3) the core of the coil should be insulated from the coil to prevent breakdown between them under transient overvoltage.

(4)线圈应尽可能绕制单层,这样做可减小线圈的寄生电容,增强线圈对瞬时过电压的而授能力。JFEM叁千伏电机引接线

(4) the coil should be made as single as possible, so that the parasitic capacitance of the coil can be reduced, and the capacity of the coil to enhance transient overvoltage is enhanced.
