新型矿用隔爆馈电开关智能保护器的研究

In order to ensure safety of mine production, it is necessary to install over-current protector in underground low-voltage feeder switch.

为保障煤矿生产的安全性，煤矿井下低压馈电开关中必须装设过电流保护装置。

SrTiO_3 varistors have been widely used as transient high-voltage protector and surge arrestor in the field of low voltage, such as restraining the noise of micro direct-current machine or source input, protecting the switch of inductive load or silicon controlled rectifier transwitch, and by-pass capacitors.

SrTiO3压敏电阻广泛用于低压领域作为过压保护和浪涌吸收元件，如用于微直流电机及电源输入端抑制噪声、保护感性负载或可控硅开关、作旁路电容器等。
