Problems solved by technology

It is difficult to find out in time if the grounding copper bar is stolen. If it is missing, the equipment is easily damaged by lightning strikes, and the secondary circuit is easy to cause the microcomputer protection device to malfunction or refuse to operate due to interference, which seriously affects the safe and stable operation of the substation equipment.
After the grounding copper bar is stolen, it needs to be repaired in time. During the restoration process, it is necessary to spend a lot of money to purchase high-quality copper bars, and it needs multi-disciplinary joint operations such as civil engineering, protection, welding, etc., which is labor-intensive and time-consuming. theft doesn't happen again

The controlled first station communication room is connected with a controlled first station monitoring room through a network line, and the controlled second station communication room is connected with a controlled second station monitoring room through a network line. The system provided by the invention is remotely connected with keyboard, video ports and mouse ports of the controlled first station monitoring room and the controlled second station monitoring room through a KVM server, and achieves the remote access to a controlled station monitoring background system in the centralized control office room, and achieves the remote obtaining and control of various types of signals of transformers.

Description

technical field [0001] The invention relates to an alarm device, in particular to a substation remote monitoring system based on KVM technology. Background technique [0002] The cable trench is an important construction facility of the substation. The grounding copper bar in the cable trench is installed on the inner wall of the cable trench to protect the feeder and equipment to prevent damage to the substation equipment caused by lightning strikes. At the same time, it plays a good role in grounding and anti-interference in the secondary circuit. , to prevent the microcomputer protection device from malfunctioning or refusing to move. [0003] Because the grounding copper bar is made of pure red copper and has a high recycling value, it has become the profit target of many criminals. Although the substation has strengthened personnel security, the grounding copper bar is still stolen from time to time. Since the grounding copper bar is difficult to find in time if it is ...
