接地问题,对于计算机来说是一个十分重要的问题,特别是对小型以上及包含有大规模集成电路插件的各种计算机尤为重要。所以一般机型都明确要求计算机的地线要与大地联接。其目的一方面是出于安全考虑,当由于意外事故引起的电击时,安全地提供低阻的对地联接起到回线作用,从而使保护装置(熔断器、断路器)动作断电;另一方面也为计算机系 The problem of grounding is a very important issue for computers, especially for small and large computers that contain large-scale integrated circuit plug-ins. Therefore, the general model clearly requires that the computer’s ground wire be connected to the earth. On the one hand, for the purpose of safety, when a shock due to an accident is caused, a low-resistance ground connection can be safely provided to act as a loop, so that the protection device (fuse, circuit breaker) can be powered off; On the one hand, it is also a computer department.
