商品详细描述
江苏春晨电缆有限公司生产供应JG型3000V电机引接线供应JG型3000V电机引接线,变压器并列运行应满足什么条件?
What conditions should the parallel operation of the transformer meet?
答:变比相等 、连接组别相同 、短路电压相同 三个条件。
Answer: three conditions: the ratio of transformation is equal, the connection group is the same, and the short circuit voltage is the same.
14. 测量高压电压和大电流为什么使用互感器?
14., why do I use high voltage and high current to use transformers?
答: ( 1 )扩大了仪表的使用范围。只要用不同的变压比和变流比的互感器与满度电压是 100V 的电压表和满度电流为 5A 的电流表配合使用,就可以测量各种电压和电流。
Answer: (1) expanded the scope of the use of the instrument. A variety of voltages and currents can be measured as long as the transformer with different voltage variable ratio and variable flow ratio is used with the voltmeter of 100V and the current meter with full current of 5A.
( 2 )使仪表、继电器的规格统一、易于标准化、大批量生产。
(2) uniform specifications for instruments and relays, easy standardization and mass production.
( 3 )使用互感器作为一次电路与二次电路的中间元件,隔离了高电压的危险,也防止了二次电路故障对一次电路的影响。
(3) using the transformer as the intermediate element of the primary circuit and the two circuit, the danger of high voltage is isolated and the influence of the two circuit faults on the one circuit is also prevented.
15. 什么是开关设备?
15. what is the switchgear?
答:主要用于发电,输电,配电,和电能转换有关的开关电器以及这些开关电器相关联的控制,检测,保护及调节设备的组合的统称.
Answer: it is mainly used for power generation, transmission, distribution, and electrical energy conversion related switch appliances and the control, detection, protection and regulation of these switching devices.
16. 什么是控制设备?
16. what is the control device?
答:主要用来控制受电设备的开关电器以及这些开关电器相关联的控制,检测,保护及调节设备的组合的统称。
Answer: it is mainly used to control the switchgear and the combination of control, detection, protection and adjustment equipment of the switchgear.
17. 什么是过电流?
17. what is over current?
答:超过额定电流的任何电。
Answer: any electricity exceeding the rated current.
18. 电流是如何形成的?
How is the 18. current formed?
答:导体中的自由电子在电场力作用下作规则的定向移动,就形成电流。
Answer: the directional movement of the free electrons in a conductor in the electric field under the effect of the rules of the current form.
19. 电能质量的指标有哪几项?
19. what are the indicators of the quality of electricity?
答:电压偏差、电压波动与闪变、电压正弦波畸变率、频率偏差。
Answer: voltage deviation, voltage fluctuation and flicker, voltage sine wave distortion rate and frequency deviation.
