Transformer substation protection system

Abstract

The invention discloses a transformer substation protection system. The system comprises a fire alarm system, a small animal repelling system, a signal protection device and a steel structured kit, wherein the fire alarm system comprises a trigger device, a fire alarm controller, a fire alarm device, a fire-fighting linked controller and automatic fire-fighting equipment, the animal repelling system comprises a snake repeller, a mouse repeller, an wireless integrated controller and a microcontroller, the snake repeller and the mouse repeller are electrically connected with the wireless integrated controller, the signal protection device comprises a cable and a cable signal transmitter, an additional wire is arranged on the lower end of the cable, signal generators are arranged on both ends of the additional wire, the signal generators are synchronized with the signal transmitter, a synchronous controller is arranged in the cable signal transmitter, and a same-frequency device is arranged in the synchronous controller. The transformer substation protection system can conduct fire pre-warning, small animal repelling and signal transmission protection.

Description

technical field [0001] The invention relates to the technical field of electric power protection equipment, in particular to a substation protection system. Background technique [0002] Electricity is the core of national energy, and energy security is related to national security. Substations are the core link of power transmission control. The higher the voltage level of substations, the larger the power supply range, and the more important their status. The idea of ​​safety first runs through all aspects of work. every aspect. [0003] A substation is a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. According to the size, the small ones are called s...

AI Technical Summary

Problems solved by technology

[0004] If a fire or other disaster occurs in the substation, it will cause a large-scale power outage and cause serious economic losses; at the same time, small animals are everywhere, and basically they are active in other seasons except winter. Among the small animals that cause power outages, Rats and snakes account for the vast majority, and small animals are also an important reason for fault tripping of distribution network equipment; the signal transmission of substations is transmitted through shielded wires, but due to factors such as high voltage, the generated magnetic field is very large, which affects signal transmission. The shielded wire completes the signal transmission, but it is still affected; at the same time, the temperature, humidity and dirty air in the substation will affect the service life of the equipment in the substation
