近年来，数据中心大力建设，接地电阻柜接触器柜配合使用得到了大力的推广使用，接地电阻柜接触器柜设计方案如下：

In recent years, the data center has been vigorously constructed, and the use of grounding resistance cabinet contactor cabinet has been vigorously promoted. The design scheme of grounding resistance cabinet contactor cabinet is as follows:

1. 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.
