Safety in medium and high-voltage electrical installations does not allow improvisation. In this sense, solenoid actuators for distribution switchgears play a key role as protection elements that can prevent serious accidents and costly damage to equipment.
What are solenoid actuators for distribution switchgear?
Solenoid actuators for electrical distribution switchgears are electromagnetic devices integrated into the safety systems of medium and high-voltage installations. Their main function is to act as an automatic shutdown mechanism when the system detects any anomaly that may compromise the safety of the installation or personnel.
Unlike other passive protection systems, solenoid actuators provide an active and immediate response in risk situations, becoming the first line of defense against electrical failures, overloads, or any other abnormal condition.
How do solenoid actuators work in electrical distribution systems?
The operation of these solenoid actuators is very simple: when the switchgear monitoring and control systems detect an anomaly—whether it is an overload, a short circuit, a ground fault, or any other parameter outside normal values—they send an electrical signal to the solenoid.
This signal activates the solenoid immediately and, in turn, triggers the shutdown mechanism of the distribution cell. This process occurs in milliseconds, stopping the operation of the switchgear before the anomaly can cause further damage to the installation or pose a danger to people.
Response speed is one of the most important factors in these systems, as in medium and high-voltage installations, every second can make the difference between a minor incident and a serious accident.
Solenoid actuators in primary and secondary switchgear
Solenoid actuators for distribution switchgear can be found in different electrical installations:
-
Primary distribution switchgear
In primary distribution networks, where high voltages are handled, solenoid actuators must meet very specific technical requirements. These installations require devices capable of withstanding harsh environmental conditions and providing reliable performance for years with minimal maintenance.
-
Secondary distribution switchgear
Secondary distribution switchgear, although operating at lower voltages, also requires equally reliable protection systems. The solenoid actuators used in these cases are designed to integrate with the different types of modular switchgear on the market.
-
Customized configurations
Every electrical installation has its specific characteristics, and at Nafsa we understand that there is no one-size-fits-all solution. That is why we offer multiple versions of solenoid actuators that can be adapted to virtually any type of distribution switchgear, regardless of the manufacturer or the specific design of the installation.
