They are a crucial part, especially during maintenance of the Solid Insulated Switchgear.

· Air Break Switches

They help in the sustenance of two lines or equipment of the solid insulated switchgear, thus minimizing electrocution.

This is through isolation of circuit and equipment within the switchgear.

· Barra colectora

Un embarrado es una barra o tira metálica cuya función es conectar equipos en tensión a la aparamenta.

Conducen la corriente dentro del cuadro de distribución.

No están aislados y son lo suficientemente rígidos como para mantenerse en equilibrio con el apoyo de pilares aislados.

· Transformador de corriente

The function of a current transformer is to multiply or reduce the electrical current in a solid insulated switchgear.

Ayuda a mantener la corriente entre los circuitos primario y secundario del tablero de distribución.

· Step-down Transformer

They help in the conversion of voltage from high to low, which the Solid Insulated Switchgear can use.

· Interruptor de puesta a tierra

Esto ayuda a reducir la sobrecarga eléctrica y la aparición de fallas eléctricas.

· Disyuntor

Un disyuntor ayuda a detener el flujo excesivo de corriente en el circuito eléctrico.

Esto ayuda a evitar que se produzcan fallos dentro del cuadro de distribución.

It is a metal-clad that uses SF6 gas for fault interruption and Insulation

How does a Solid Insulated Switchgear work?

The functioning of a Solid Insulated Switchgear depends on working of its components.

Cuando ocurre una falla, el relé entra en acción cerrando el circuito de disparo.

Esto se realiza mediante la desconexión automática de la línea de falla.

A continuación, las secciones sanas y operativas garantizan que haya un flujo de la carga de suministro normal requerida.

Gracias a esto, se consigue un suministro eléctrico fluido en todo el equipo, garantizando que no se produzcan daños.

La sobrecarga de la línea inhibe que la corriente realice una acción de liberación electromagnética.

Sin embargo, inicia la producción de calor por parte del elemento térmico.

El calentador calienta la lámina bimetálica provocando que se doble hacia arriba.

Esto empuja la palanca hacia arriba, haciendo que el gancho se bloquee.

Esto interrumpe el contacto primario y corta el suministro de energía.

De esta manera, cuando hay una sobrecarga, se supera la corriente establecida provocando que el disparador electromagnético produzca succión.

A combination of the suction and the impact lever results in the lap hook to rotate upwards around the shaft seat

This results in the release of the lock.

What are the Safety features of a Solid Insulted Switchgear?

The safety features of a Solid Insulated Switchgear include the following:
