Pangtulong sa Pag-imbak ng Enerhiya mula sa Solar na Transformer

Pangkalahatan ng Produkto：

Ang grid-connected energy storage auxiliary isolation transformer para sa photovoltaic power generation ay karaniwang ginagamit para sa solar inversion, na may karaniwang mga voltages na kabilang ang 800V hanggang 400V, 380V, 690V hanggang 400V, 540V hanggang 400V, atbp. (maaaring i-customize ayon sa pangangailangan); dahil sa mababang photoelectric efficiency ng photovoltaic silicon panels, ang transformer ay espesyal na nangangailangan ng mataas na efficiency. Ang photovoltaic isolation transformer ay may microcomputer intelligent time controller upang itakda ang pag-operate sa araw at pag-stop sa gabi upang bawasan ang no-load power loss, isang temperature controller upang real-timely monitorin ang operating temperature ng transformer, kontrolin ang pagsisimula at pag-stop ng cooling fan, at awtomatikong mag-stop at mag-disconnect ang transformer kapag ang operating temperature ay sobrang mataas na umabot sa itinakdang critical temperature upang maprotektahan ang seguridad ng katawan ng transformer, isang self-reset overvoltage at undervoltage protector upang maiwasan ang islanding operation, isang surge protector upang makapagbigay ng epektibong proteksyon laban sa lightning damage sa equipment at mapataas ang safety factor ng power generation system, at isang knife switch sa grid-connected side upang mapadali ang epektibong operasyon at maintenance ng equipment.

Punong Katangian:

• Smart Controls: Microcomputer time controller reduces nighttime no-load losses.

• Safety Protections:

• Temperature monitor with auto-shutdown at critical thresholds.

• Over/under-voltage self-reset protector prevents islanding.

• Surge arrester for lightning protection.

• Grid-side knife switch for maintenance.

• Flexible Configurations: Available in single/multi-unit combinations (1:2, 1:3, etc.) for scalable PV systems.
