Pangkalahatang Transformer para sa Imprastraktura ng Solar at Ipaglaban ang Pag-imbak ng Enerhiya

Pangkalahatang-ugali 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 voltages na kasama ang 800V hanggang 400V, 380V, 690V hanggang 400V, 540V hanggang 400V, atbp. (maaaring i-customize depende sa kailangan); dahil sa mababang photoelectric efficiency ng photovoltaic silicon panels, ang transformer ay espesyal na nangangailangan ng mataas na efficiency. Ang photovoltaic isolation transformer ay mayroong 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 pagtigil ng cooling fan, at awtomatikong itigil at i-disconnect ang transformer kapag ang operating temperature ay sobrang mataas na umabot sa set critical temperature upang maprotektahan ang safety ng katawan ng transformer, isang self-reset overvoltage at undervoltage protector upang maiwasan ang islanding operation, isang surge protector upang mabisa na maiwasan ang lightning damage sa equipment at mapataas ang safety factor ng power generation system, at isang knife switch sa grid-connected side upang mapadali ang effective operation at maintenance ng equipment.

Punong Katangian:

• Smart Controls: Microcomputer time controller bawasan ang no-load losses sa gabi.

• Safety Protections:

• Temperature monitor na may auto-shutdown sa critical thresholds.

• Over/under-voltage self-reset protector na nagpapahintulot sa islanding.

• Surge arrester para sa lightning protection.

• Grid-side knife switch para sa maintenance.

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