Shipping shore power system

一种船舶岸电系统

Abstract

一种船舶岸电系统,岸电系统包括变压器、陆地用电负荷和船舶用电负荷,变压器低压侧通过并联的接地断路器和接地阻抗接地,陆地用电负荷和船舶用电负荷并联,与变压器低压侧连接,其中陆地用电负荷与变压器之间设有陆用负荷断路器,船舶用电负荷与变压器之间设有船用负荷断路器,所述接地断路器与船用负荷断路器联锁;没有船舶靠岸使用岸电系统时,接地断路器合闸,使接地阻抗短接,岸电系统为陆地用电负荷供电;船舶靠岸用电时,船用负荷断路器合闸,接地断路器分闸,岸电系统通过接地阻抗接地,陆地用电负荷与船舶用电负荷共用岸电系统。本实用新型供电方式转换迅速,工作可靠,保护手段全面,提高岸电系统的利用效率和工作安全稳定性。
The utility model discloses a shipping shore power system comprising a transformer, a landing electric load and a shipping electric load. A transformer low-voltage side is grounded through a grounding circuit breaker and a grounding impedance which are connected in parallel; and the landing electric load is connected in parallel with the shipping electric load and connected with the transformer low-voltage side, wherein a landing loading circuit breaker is arranged between the landing electric load and a transformer; a shipping load circuit breaker is arranged between the shipping electric load and the transformer; the grounding circuit breaker is interlocked with the shipping load circuit breaker; the grounding circuit breaker is switched on when the ships are not in port and the shore power system is used, so that the grounding impedance is in short circuit and the shore power system supplies the electricity for the landing electric load; when the ships are in port in need of electricity, the shipping load circuit breaker is switched on, the grounding circuit breaker is switched off, the shore power system is grounded through the grounding impedance, and the landing electric load and the shipping electric load share the shore power system. The utility model has the advantages of quick conversion of power supply ways, reliable work and all-around means protection, and improves the utilization efficiency of the shore power system and the stability of work security.
