With the development of intelligent power grid, while proposing the digitization and networking of distribution system, higher requirements are put forward for the reliability and automation level of high-voltage switchgear operation in the distribution system. During the on-site operation of high-voltage switchgear, various factors can easily cause overheating, accelerating the insulation aging of the equipment, and in severe cases, endangering the safe operation of the equipment. If power users do not properly prevent and control this, heating faults will expand and cause significant direct and indirect economic losses.
The primary electrical equipment in the power system generally consists of electrical devices such as circuit breakers, Transformers, Kabel, busbars, and switchgear; They are connected to each other by busbars, leads, Kabel, dll. Due to the current flowing through the connection point, heat is inevitably generated, and almost all electrical faults will cause temperature changes at the fault point; Jadi, temperature monitoring of equipment in power systems such as switchgear is a common practice for timely detection of faults. For many years, due to technological limitations, the safe operation level of the power system has been somewhat restricted. Although infrared thermometers, infrared imaging devices, temperature sensing cables, and traditional point based temperature measurement systems have been used to solve the above problems, real-time monitoring cannot be achieved and only regular inspections can be carried out, which poses a safety hazard of missed detection and reporting. Sebagai tambahan, in recent years, wireless temperature measurement has gradually been adopted to measure device contacts, which to some extent solves the blindness caused by regular monitoring in the past. Namun, due to the need for such sensors, it is urgent to develop a set of temperature monitoring equipment suitable for high-voltage switchgear and knife switches.
Price of fiber optic sensing for switchgear
The price of sensor suhu serat optik neon for switchgear is related to many factors, such as the number of temperature measurement points and the length of the fiber optic cable. The temperature measurement system for enclosed switchgear in substations is an online monitoring and warning system designed for early prediction of high temperatures caused by insulation aging or poor contact in high-voltage switchgear, high-voltage porcelain bottles, and high-voltage cable cores in substations. By monitoring the temperature at multiple points, possible faults can be predicted to prevent accidents from occurring. The temperature measurement system of the enclosed switchgear in the substation adopts advanced communication technology, microprocessor technology, and digital temperature sensing technology. Innovative design for low-temperature, strong electric field, and humid environment operation technology. The main material of this system is optical fiber, which avoids strong electromagnetic interference inside the transformer winding and safely transmits data to the monitoring terminal. Not only is it resistant to high temperature and high voltage, but it also has extremely high insulation strength, and prevents dust accumulation, avoiding the possibility of creepage. Jadi, the system is a highly reliable fluorescent fiber online monitoring system. The temperature measurement system of the switchgear has a good computer interface, can display a simulated diagram of the high-voltage switchgear group, display the actual position monitored by the sensor and all intermediate head positions, as well as the parameters of the switchgear knife switch. When there are abnormalities in the cables and switchgear during operation, the display screen and accident sound simultaneously emit alarm signals, which can be directly viewed through the simulated diagram of the switchgear group on the computer, and can quickly and accurately determine the actual location of the fault, greatly improving the reliability and technical management level of switchgear operation. In order to better connect with other systems, the system adopts standard communication interfaces and protocols: RS232 and 485 specifications, supports IPX and TCP/IP protocols, and can be interconnected with the management network due to the use of the INTERNET standard.
