cada una de ellas. En este caso, el administrador del quiosco
maneja la tienda, es propietario del sistema y es responsable
de cobrar los cargos por uso de energía a los otros arrendatarios
para el funcionamiento y mantenimiento del sistema.
NELSON: Descríbenos el diseño del sistema eléctrico
de los quioscos.
SZABLYA: El diseño eléctrico de la configuración inicial
de los quioscos se muestra en la figura 3. Son diez paneles
FV, cada uno con una capacidad de 350 W, que están
conectados a un inversor híbrido.
La red CA arranca y se abastece con el subsistema de
formación de la red de los inversores híbridos que está unido
al banco de baterías. El subsistema de seguimiento de la red
de los inversores híbridos puede suministrar energía directamente
de los paneles FV a la red CA sin que pase por las
baterías. El inversor de seguimiento de la red sincronizará
automáticamente los paneles FV a la red CA cuando se cierre
el disyuntor. Se pueden conectar varios conjuntos de
inversores de seguimiento de la red y formación de la red en
paralelo en un mismo sitio.
El quiosco formará una carga ancla para el pueblo. Con el
tiempo, se podrá extender la red de CA de 230 V (VCA) en
las líneas de distribución de todo el pueblo. El diseño es altamente
ampliable. Se podrán conectar otros generadores FV
con inversores de formación de redes en distintos lugares.
NELSON: Explícanos el análisis de los planes para
que las mujeres cuenten sus historias a los compradores de
gemas talladas y pulidas de Kuumba.
septiembre/octubre 2022
KACHINGA: Se piensa que la industria tiene que ser
un campo de hombres. Las empresas mineras han preferido
a los hombres sobre las mujeres por la creencia de que esas
ocupaciones son para ellos y no para ellas. Existe la idea de
que las mujeres no son lo suficientemente fuertes para estar
en las máquinas durante largas horas.
Por ello, hemos diseñado tarjetas de regalo, como la que
se muestra en la figura 4, para contar las historias de nuestras
talladoras y lo que las piedras preciosas significan para
ellas. En el futuro, esperamos diseñar con láser un grabado
de los nombres de las mujeres que han tallado las piedras.
Cuando una persona compra una piedra preciosa de Kuumba
figura 4. Cada piedra preciosa tiene una etiqueta con un
mensaje igualmente hermoso de cómo este trabajo dará
esperanza y sustento a la talladora y pulidora.
