模块化组合式雷达直流应急电源研究

Research on Modular Combined DC Emergency Power Supply of Radar

直流电源作为雷达的二次电源,不仅种类规格多、而且对可靠性、稳定性要求高。然而,由于负载、电网、自然环境等的影响和工作环境的电磁干扰,直流电源容易出现故障,这对雷达情报的正常传递造成致命的影响。本文提出了一种模块化组合式直流电源,作为故障情况下雷达的应急电源,保障直流电源连续不间断的工作,确保雷达直流供电的连续性和可靠性。通过模块化设计,降低了成本、减小了体积重量,提高了可维护性以及可靠性,通过组合式设计,可以适应不同型号雷达的应急供电需求,减少了直流电源数量,提高了通用性和全面性。

DC power supply is generally used as the secondary power supply of radar; there are high requirements to stability and reliability of DC power supply. However, DC power supply is prone to be failure because of impact of load, power net, natural environment and electromagnetic interference at the working place, which will affect fatally to transmission of radar intelligence. A modular combined DC power supply which can be used as emergency power supply of radar in case of power failure is proposed. The DC emergency power supply can ensure continuous operation of DC power supply and apply DC power supply to radar continuously and reliably. Based on modular design, the DC emergency power supply features lower cost, small volume and less weight, maintainability and reliability are also improved. Through the combined design, it can meet emergency power supply requirement of different types of radar, therefore number of DC power supplies is reduced, and universality get improved.
