每台发电机组配置一个接地电阻柜
发布人：管理员 发布时间：2022-7-21
每台发电机组配置一个接地电阻柜。接地电阻柜由高压接触器或断路器，接地电阻，接地保护继模块组成。如并机系统，则需加装一个PLC控制模块，用于控制每个接地电阻的断路器在正确的时间闭合或断开。因为在多台高压并机系统中只允许一台高压柴油发电机组接地。
1. Each generator set is equipped with a grounding resistance cabinet. The grounding resistance cabinet is composed of high voltage contactor or circuit breaker, grounding resistance and grounding protection relay module. For parallel system, a PLC control module should be installed to control the closure or disconnection of each grounding resistance circuit breaker at the right time. Because only one high-voltage diesel generator set is allowed to be grounded in the multi-high-voltage parallel system.
2. 多台柴油发电机组共用一个接地电阻，接地电阻连接采用多个高压接触器控制。整个系统配置一套接地电阻柜。接地电阻柜内配置一套接地电阻器、一只电流互感器；另外配置一台接地开关柜（接地接触器柜）内有：多个高压接触器。
2. Many diesel generators share one grounding resistance, and the grounding resistance connection is controlled by multiple high voltage contactors. The whole system is equipped with a grounding resistance cabinet. The grounding resistance cabinet is equipped with a grounding resistor and a current transformer, and another grounding switch cabinet (grounding contactor cabinet) is equipped with multiple high voltage contactors.
