Advantages of the main host of the fiber optic temperature measurement system for switchgear
1. Flexibility.
The temperature measurement device comes with a corresponding screen display, which can independently display the alarm status, set alarm thresholds, view alarm related records, and process alarms. After the device is successfully connected to the network, the above operations can be carried out on the computer system platform.
2. The transmission of data is not affected.
On site synchronous measurement and data transmission are achieved, and the measurement unit uses different data buses for data transmission operations, which can eliminate the influence of external factors on the monitoring results, making the data of each monitored device have strong comparability.
3. Quickly trigger an alarm.
The data collection frequency is higher and more accurate, and it can collect data according to the user's settings, with a minimum cycle of less than one second.
4. Accurate prediction of device operation status.
Calculate and analyze the development trend of the temperature values of the tested switchgear, combined with working condition information, to further evaluate the aging situation of the switchgear and the application of fluorescent fiber optic temperature measurement at important nodes of the switchgear.
How to install the fiber optic temperature measurement system for switchgear
1. Install monitoring host
Install a temperature measurement system monitoring host in the control room monitoring cabinet, and the operator can set up a monitoring computer in the control console for remote monitoring.
2. Installing a fiber optic thermometer
Connect the ST-FC connector to the fluorescent temperature measuring probe. The fluorescent fiber optic thermometer can be pre embedded inside the silicone sheath, and the fiber optic connector can directly contact the wires present in the cable connector, which can detect the true temperature of the connector.
3. Installing fiber optic sensors
3.1. The switchgear contacts are used to install sensors.
The position where the static and dynamic contacts of the switchgear are connected to each other is the heating center point. Under the influence of the insulation sleeve, the internal space at this position is not very large. Therefore, when designing sensors, full consideration should be given to this, and attention should be paid to ensuring that the distance between them and the moving contacts is within a safe range when installing accessories.
3.2. The cable joints of the switchgear are used for installing sensors.
Attach the sensor to the cable joint with the help of aviation specific silicone, and bind and fix it with a dedicated zip tie.
3.3. Internal wiring of switchgear.
It is best to arrange cables and tail fibers inside the cabinet along the corners of the cabinet, or use secondary wires or dedicated cable trays
Bundling brings certain convenience for subsequent maintenance of the switchgear.
Precautions for installing and maintaining optical fibers
1. The installation and maintenance of optical fibers shall be carried out by technically trained personnel who have received professional and strict training to prevent them from being stretched, squeezed or twisted, and the bending radius of the optical fibers shall exceed 40mm.
2. In the actual installation and installation process, attention should be paid to avoiding heavy pressure on the optical fiber, and it is also necessary to avoid the optical fiber
Damage caused by being tightly clamped or punctured by sharp objects.
3. During the process of laying optical fibers, attention should be paid to avoiding twisting, knotting, and back buckling
Wait for the question.
4. Pay attention to holding or fixing the fiber optic ST connector in your hand to avoid shaking.
5. If the turning position of the optical fiber needs to pass through an acute angle, various scientific guidance devices such as a flexible bending protective layer need to be added.
6. When the optical fiber penetrates through the shell, it needs to pass through a horn shaped soft tube mouth or a protective plastic tube with a protective mouth. 7. The excess length of the optical fiber needs to be coiled in a circle, with a radius exceeding 10cm, ensuring reliable fixation.
8. When there is no fiber optic connector connected, protective caps should be placed on both ends to prevent dust from adhering.
9. When disassembling the transmitter, the fiber optic cable needs to be removed, and the fiber optic connector needs to be fixed before disassembling the transmitter.
Fiber optic temperature measurement software system for switchgear
The software system can monitor the current regional temperature in real time, remotely control data information, issue low and high temperature alarms, develop temperature curves, access historical data, etc.
Effect of fiber optic temperature measurement system for switchgear
Install the fluorescent fiber optic temperature measurement system on the main control room host, collect real-time temperature data of each node of the switchgear, automatically process and study all input data, and use the system to directly view it. By assembling the monitoring software into a computer, it can be connected to the power system, remote monitoring, and fire protection according to the actual situation, integrating its functions to form a more powerful and comprehensive system,
Shared data resources for easy management and control. At the same time as using fluorescent fiber optic temperature measurement for the switchgear, using traditional infrared thermometers to detect temperatures at different nodes, the temperature values measured by the two differ by
Within 1 ℃, the results confirm the strong feasibility of this new temperature measurement method.
Why does the switchgear need temperature measurement
In the power system, high-voltage switchgear is a crucial type of equipment, mainly responsible for avoiding line faults, controlling transmission lines, protecting lines, etc. If the switchgear is used for a long time, the internal busbar connection points, cable joints, circuit breaker contacts, etc. are prone to heating and contact problems under the influence of loosening and oxidation. If a large current passes through at this time, the temperature at the above positions will rise, and severe heating will lead to a significant increase in contact resistance, making the heating situation even more severe. Over time, this can easily lead to serious accidents, posing safety hazards to system operation, and even triggering large-scale fires. To avoid this type of accident, it is crucial to address the issue of increased temperature inside the cabinet. By using fluorescent fiber optic temperature measurement, electromagnetic interference and insulation issues can be avoided, and the measured results have high accuracy.
