| 1. | Mining type flameproof switchgear with vaccum circuit breaker for low - voltage alternate circuit
矿用隔爆型低压交流真空馈电开关 |
| 2. | The circuits in which both the excited sources and the responses are all sinusoidal shapes are called sinusoidal alternating circuits
激励和响应均为正弦量的电路称为正弦交流电路。 |
| 3. | Ac ceramic capacitors mainly consist of tatanate . they are mainly used in transwire and alternate circuits applications , with highest voltage of ac 400v
交流瓷介电容器主要由钛酸盐组成，主要特点可用于跨电源线及交流电路中用，最高电压为交流400v 。 |
| 4. | 4 in the sinusoidal alternating circuit that only contains a capacitor , the voltage across the capacitor lags the current through it by 90 , and they have the same frequency
在只含有电容的正弦交流电路中，电压滞后电流90 ，且它们具有相同的频率。 |
| 5. | 3 in the sinusoidal alternating circuit that only contains an inductor , the voltage across the inductor leads the current through it by 90 , and they have the same frequency
在只含有电感的正弦交流电路中，电压超前电流90 ，且它们具有相同的频率。 |
| 6. | Whereas if the contacts are in series with the alternating circuit , due to the passing zero property of voltage , we must evaluate the condition of contacts according to voltage value
但当触头接入交流电路中时，由于电压有过零的特征，所以要根据电压有效值来判断触头是打开还是闭合。 |
