Chapter III is a common low-voltage electrical appliances, leakage protection device installation and basic requirements.

第三章是常用低压电器、漏电保护器的安装及基本要求。

This text has analyzed the common malfunction of the asynchronous motor at first. And then it, which is based on symmetrical weight theory, has drawn accurate criterion of the trouble of the motor, confirmed the protective measures of different troubles. Finally, it has realized kinds of protection functions, such as short-circuit protection, rotate-stop protection, over-heat protection, negative current protection, zero current protection, low-voltage protection, over-voltage protection, overlong start-up time protection, frequent start-up protection, lock protection of electric leakage and so on.

本文首先分析了异步电动机的常见故障，以对称分量法为依据，采用检测过流幅值、负序电流、零序电流的方法，得出了电动机故障的准确判据，确定了各种故障的保护措施，对电动机实现了短路、堵转、过热、负序电流、零序电流、低电压、过电压、启动时间过长、频繁启动、漏电闭锁等保护功能。

The samples with a diameter of 14mm have a nonlinear coefficient of about 50, a breakdown electric filed of about 350V/mm and a leakage current of less than 5μA, and the withstanding surge peak current of 8/20μs waveshape is about 2kA, which meet practical requirement.

获得电性能接近实用化的SnO2压敏陶瓷样品，其压敏电压V1mA约为350V/mm，非线性系数α达到50，漏电流小于5μA，并且在8/20μs脉冲电流冲击试验中，直径14mm的样品能够经受2kA的脉冲峰值电流。

ZnO varistors is characterized by its excellent nonlinear volt-amppere characteristic and very low leakage current under steady-state voltage.

氧化锌压敏电阻器具有优良的非线性伏安特性，在稳态工作电压下漏电流很小。

Leakage current of varistor is related to voltage and temperature, and caused by its microstructure.

氧化锌压敏电阻器漏电流宏观上与电压、温度有关，实质在于电阻体的微观结构。
