110KV Substation in Hebin Park

Background

With the rapid development of electric power industry, the modern power system is developing towards the direction of large power grid, large unit, ultra high voltage and large capacity.
In order to ensure the stability and reliability of the power system, the safety level of the power equipment is also put forward higher requirements.
However, partial discharge is more common, partial discharge is a kind of pulse discharge, which is electric power equipment insulation in a sufficiently strong electric field in the local area of discharge.
It will produce a series of physical phenomena and chemical changes in the internal and surrounding space of power equipment, such as light, sound, electrical and mechanical vibration and other physical phenomena and chemical changes, in order to monitor the insulation state of power equipment to provide detection signal.
Project requirements
The safety level of the power cable is very high in the project of cable line partial electro-discharge monitoring. In time, the system should be able to make timely and accurate judgment of the insulation condition of power cable and make early warning of the discharge. That Provide necessary guidance to the normal operation of the cable, improve the reliability, security and efficiency of the equipment operation.
System Diagram
Scheme introduction
In this scheme, the industrial Ethernet switch IES215-2F is used to transmit data from the partial electro-discharge collector. Network using bus and star structure: Inside the station using UTP transmission, outside the station using optical fiber transmission, reliable and stable transmission. Data gathered by the switch to the monitoring center, to achieve data acquisition and control of the whole system and real-time monitoring.
Scheme advantage
Bus type and star type structure to make network data reliable and stable transmission. The switch uses industrial grade design, no fan, low power consumption, support for -40~75℃ working temperature, metal shell, IP40 protection class. Have good resistance to interference. Provide an economical and effective solution to the harsh industrial environment.
