Substation grounding copper bar anti-theft alarm device

Abstract

The invention discloses a theft-proof alarm device for a substation ground copper bar. The theft-proof alarm device comprises a copper bar, a signal line is arranged on the copper bar, the signal line is connected with an alarm device through a lead, the alarm device is connected with an early warning extension through a lead, the early warning extension is connected with an early warning host through wireless signals, and the early warning extension comprises a shell, a loudspeaker, a nut, a lead screw, a slide rail, a battery, a wireless signal transmitting device, a pulse generating device and a step motor. The early warning extension, which receives current pulse sent by any alarm device, gives a sound-light alarm, and meanwhile, sends a wireless alarm signal to the early warning host installed in a main control room of a substation; and a liquid crystal screen of the early warning host can display an alarm zone. The copper bar is installed on the inner wall of a cable channel, and is used for protecting feeder lines and equipment to prevent the substation equipment from being damaged by lightning stroke.

Description

technical field [0001] The invention relates to an alarm device, in particular to an anti-theft alarm device for substation grounding copper bars. 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 i...

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
