Protective application of connecting rod lock in power equipment
With the rapid development of social economy and the progress of science and technology, people's demand for electricity is getting higher and higher, and as one of the important devices to ensure the safe and stable operation of power system, connecting rod lock is more and more widely used in power equipment.
1. What is a connecting rod lock?
Connecting rod lock is a kind of safety protection device used for electrical switchgear, distribution box and other power equipment. It realizes effective control of equipment operation sequence by combining mechanical mechanism with electronic technology. Simply put, it is a device that can ensure that power equipment operates according to established procedures, thus avoiding accidents caused by misoperation.
Second, the functional characteristics of the connecting rod lock
1. High safety: the connecting rod lock can effectively prevent unauthorized personnel from operating power equipment without authorization, and reduce the probability of safety accidents;
2. Strong reliability: it is made of high-quality materials and can maintain normal working conditions in harsh environments after strict testing and verification;
3. Simple operation: it has an intuitive operation interface and convenient man-machine interaction mode, which is convenient for staff to quickly master the use method;
4. Wide application range: suitable for various types of power equipment and occasions.
Third, the concrete application case analysis of connecting rod lock in power equipment
(1) Substation
1. Prevent misoperation of breaker or on-load knife brake during brake switching operation;
2. Realize the interlocking relationship between circuit breaker and disconnector to avoid short circuit failure;
3. Control the oil level alarm signal of transformer and handle the abnormal situation in time;
(2) Wind farms
1. Install a connecting rod lock in the fan tower to limit the rotation angle of the blades, so as to reduce the vibration impact caused by strong wind blowing;
2. Install a connecting rod lock on the ditch cover plate of the high-voltage cable in the booster station to prevent irrelevant personnel from entering the dangerous area and causing injuries;
3. Set the emergency stop button and connect it to the PLC control system. Once the abnormal situation is detected, take measures to stop the generator set immediately.
IV. Conclusion
In a word, through the study of the above contents, we can know that the connecting rod lock, as a new and reliable protective device, plays an extremely important role in the power industry. In the future, with the continuous improvement and perfection of science and technology, it is believed that more advanced technologies and products will emerge to provide more powerful support for China's energy security!
