Protective device for motor for spring operating mechanism

With the gradual deepening of the automation of the power system, the spring operating mechanism is used in large quantities, and the demand for the corresponding motor for spring operating mechanism will gradually increase. In order to ensure that the equipment can always maintain its normal working condition, it is necessary to install corresponding protection devices for the motor of the spring operating mechanism.

 

With this kind of protection device, a reliable disconnection energy storage circuit can be provided for the motor of the spring operating mechanism, the motor for protecting the spring operating mechanism is not burned down, and the entire operating mechanism can also maintain a normal and stable operating state, avoiding defects. influences.

 

The protection device of the motor for spring operating mechanism is mainly composed of several parts such as a limit switch, an energy storage motor and an arc extinguishing circuit. The trip switch and the motor of the spring operating mechanism are directly connected together to provide a control switch for the power supply. The arc extinguishing circuit in the device is connected in parallel at both ends of the normally closed contact of the limit switch to absorb the DC arc energy of the motor for the spring operating mechanism.

 

Not only that, the spring protection mechanism for the motor-operated mechanism also has an additional timing circuit that is connected to the motor and is activated simultaneously with it to set the protection time limit. Under normal conditions, the time limit for protection is greater than the time required for normal energy storage by the spring operating mechanism motor.

 

The protection device of the motor for spring operating mechanism also includes a switching element which is connected to the motor and the timing circuit as a switching element of the energy storage circuit. This component includes field effect transistors for voltage divider resistors and voltage-controlled semiconductor devices. The divider resistors provide operating voltage for the field effect transistors.
