The necessity of temperature measurement device for 10KV high-voltage switchgear
The rated operating current of switch structure, overhead wires and cables determines the actual carrying capacity of various high-voltage transmission circuits. වාර්තමානයේ දී, high-voltage switchgear with vehicle mounted or mid mounted control circuit breakers is widely used in various fields of electric energy production, which greatly increases the probability of heating faults occurring at the contact position between the control circuit breaker and the high-voltage switchgear, greatly affecting the load capacity of the electric energy transmission line, restricting normal production development, and even causing damage accidents to the high-voltage switchgear in serious cases. According to the occurrence of heating accidents in high-voltage switchgear in recent years, the vast majority of heating phenomena occur on high loads of switchgear.
FJINNO has independently developed a 10KV high-voltage cabinet temperature online monitoring device based on the actual heating conditions of the high-voltage switchgear, and provided a corresponding solution for the 10KV switchgear fluorescent fiber temperature measurement system. The temperature measurement standard for high voltage switchgear is the standard for the temperature rise of 10KV high voltage switchgear. High voltage switchgear is the most important part of power equipment, so temperature control and monitoring of high voltage switchgear are very important. The commonly used temperature measurement methods for 10kV switchgear are 6-point temperature measurement and 9-point temperature measurement of switchgear. Contact temperature measurement and busbar temperature measurement of high voltage switchgear are common temperature rise and heating temperature measurement points for switchgear. Substation switchgear temperature measurement is an important project for bidding by power equipment enterprises. Infrared wireless temperature measurement of switchgear has many disadvantages, and a good temperature measurement method for switchgear is the switchgear fluorescent fiber temperature measurement online system
10KV switchgear fiber optic temperature measurement system
Fluorescent fiber optic temperature sensors appeared as early as thirty years ago. Due to their use of pure optical principles for temperature measurement, these sensors have unparalleled advantages over traditional sensing technologies in terms of electromagnetic interference resistance, high-voltage insulation, stability and reliability, sensitivity, and miniaturization. වර්තමානයේ, with the gradual improvement of intelligent power grids, fluorescent fiber optic temperature measurement has been commercialized in the power industry and other industries that require power equipment. Its application in monitoring the contact temperature of power switchgear is particularly urgent. Due to the uniqueness of the moving contacts in switchgear, it is difficult for general temperature measuring equipment to directly test their temperature, resulting in frequent incidents of switchgear explosions. Traditional temperature measurement methods can only be applied to the temperature detection of static contacts in newly put into operation power switchgear, and cannot detect the temperature of moving contacts; On the other hand, there is a lack of direct methods for measuring the temperature of static and dynamic contacts in the current operating switchgear on the market.
High voltage switchgear fluorescent fiber optic temperature measurement device, including fiber optic temperature measurement system, fiber optic temperature measurement host, sensing fiber optic, temperature acquisition, digital output and RS485 communication, display module, ආදිය.
The fluorescent fiber optic probes of the fluorescent fiber optic temperature measurement module are installed at the contact positions of the incoming and outgoing lines of the high-voltage switchgear. The temperature acquisition will collect real-time data from the multi-channel fluorescent fiber optic temperature measurement module and transmit the data to the CPU main control. Then, the real-time temperature data obtained will be displayed on the LCD screen to show the temperature values at the contact positions of the incoming and outgoing lines of the high-voltage switchgear. If the temperature of the incoming and outgoing contact points of the high-voltage switchgear exceeds the alarm set value, a prompt will be displayed at the corresponding position on the screen, and the alarm device will be activated to trigger external alarm temperature control tripping and other related equipment.
