It is a core element used in automatic reclosing devices in power systems. It is mainly used to restore the normal operation of the power system through automatic reclosing operation in the event of a transient fault.
The working principle of BCH-5 reclosing relay is that when the circuit breaker trips due to the current fault of the power system, the reclosing relay will automatically reclose the circuit breaker according to the preset conditions and time delay, so that the power system can return to normal power supply. If the fault is transient, the power system will continue to operate normally after a successful recloser;If the fault is permanent, after the reclosing fails, the reclosing relay disconnects the circuit breaker again and sends out a corresponding signal for further troubleshooting.
The BCH-5 reclosing relay has the following characteristics:
High reliability: The use of high-quality raw materials and strict production process ensures the long-term stability and reliability of the product.
Good flexibility: The time delay and number of reclosers can be adjusted according to the actual needs of the power system.
Fast action speed: The high-performance electromagnetic mechanism and spring mechanism are used to ensure the speed and accuracy of the action.
Easy maintenance: simple structure, easy to operate, easy to maintain and maintain.
The following precautions need to be taken when using the BCH-5 recloser relay:
During installation and use, it is necessary to comply with relevant safety operation procedures to ensure the safety of personnel and equipment.
The reclosing relay should be inspected and maintained regularly to ensure that it is in good working order.
In the process of use, it is necessary to pay attention to the operation of the reclosing relay, and find and deal with abnormal phenomena in time.
According to the actual situation of the power system, the time delay and the number of reclosing should be reasonably set to avoid unnecessary damage to power equipment and lines.
In short, BCH-5 reclosing relay is the core component of an important automatic reclosing device in power system. It has the advantages of high reliability, good flexibility, fast action speed and convenient maintenance, which can effectively improve the power supply reliability and stability of the power system.
