The circuit breaker control, after storing energy promptly, is equipped with a anti-trip control circuit. The control circuit should immediately reflect the position of the circuit breaker and the integrity of the power supply circuit. To ensure every step of the circuit breaker is trustworthy, various locking methods should be assembled in the control circuit. When conditions are not met, the actual operation of the circuit breaker should be terminated. When an abnormality occurs in the circuit breaker's computer operating system, the switch power supply circuit should be turned off. When the working pressure of the hydraulic press or the standard air pressure operation mechanism is too high or too low, the torsion spring operation mechanism does not store energy. For SF6 circuit breakers, the SF6 working pressure is one level lower. These situations can cause the normally open and normally closed contacts in the reclosing control circuit to be disconnected, and the circuit breaker cannot be separated.

The controller must be configured with motor constant current power supply control skills: matching the motor's running current with the dynamic operating current to enhance the motor's starting torque balance. This ensures safe operation of the motor and all equipment during common mechanical gear fault torque increases. Therefore, the controller should have a rational selection of current control components, be applicable to all motors, and possess reasonable safety management functions. This eliminates the need for widespread adaptability of new energy electric vehicle controllers, making the motors and controllers of new energy electric vehicles no longer require on-site equipment matching, simplifying machinery and application processes.
