自行火炮初级供电系统负载特性的研究

Research on Load Characteristics of Self-Propelled Gun Primary Power Supply System

自行火炮初级供电系统的设计依据是用电设备的负载特性。研究自行火炮初级供电系统的负载特性,其中绝大部分负载设备所需电能为直流电能,即使采用交流发电装置,用电设备所需电能也须经过二次电源变换后使用,因此,自行火炮初级供电系统的本质是直流系统。按此思路设计自行火炮初级供电系统时可忽略发电装置输出电能的频率、波形失真度和相角对称度等交流技术指标,使设计出的自行火炮初级供电系统结构简明、运行可靠和费效比高,这种设计理念值得研究和推广应用。

The design basis of self-propelled gun primary power supply system is load characteristics of electrical equipment. Load characteristics of self-propelled gun primary power supply system were studied. The vast majority of electrical energy required by electrical equipment is DC electrical energy, even using AC generator equipment, electrical energy required by electrical equipment should be transformed by use of secondary power supply, thus the nature of self-propelled gun primary power supply is DC system. According to this principle, the exchanging technical indexes such as frequency of electrical energy output by generator equipment, waveform distortion, symmetry phase angle etc. can be neglected in process of design of self-propelled gun primary power supply system. By means of this method, the designed self-propelled gun primary power supply system has advantages of simple structure, reliable operation and high cost-effective ratio, and this design theory is worth to research and promote to use in gun system design.
