產品概述 Product overview

XHLX-AC 光伏交流匯流箱是適用于光伏組串式發(fā)電系統(tǒng)中，承接組串式逆變器與交流配電柜或升壓變壓器的重要組成部分，此匯流箱的進線采用斷路器輸入，輸出采用斷路器或負荷隔離開關，母線匯流后采用二級防雷保護，系統(tǒng)額定電壓為 AC690V．防護等級與組串式逆變器同級為 IP65．達到室外安裝的要求，滿足防水，防塵、防紫外線，防鹽霧腐蝕等。 

該產品大大簡化了組串式逆變器與交流配電柜或升壓變壓器之間的接線，此產品內部結構簡潔明了，布線整齊合理。可靠性高，維護簡單。戶外壁掛式安裝，能適應各種惡劣環(huán)境。除了標準材質和尺寸外，可按用戶要求定制。 

XHLX-AC photovoltaic AC bus box is an important component that is suitable for photovoltaic series-connected power generation system. It receives series-connected inverter and AC power distribution cabinet or step-up transformer. The incoming line of the bus box adopts circuit breaker input, and the output adopts circuit breaker or load isolating switch. After bus convergence, secondary lightning protection is adopted. The rated voltage of the system is up to AC 690V. The protection level is IP65．at the same level as the series-connected inverter. It meets the requirements of outdoor installation and meets the requirements of waterproof, dustproof, ultraviolet protection, salt fog corrosion protection, etc. This product greatly simplifies the wiring between the series inverter and AC distribution cabinet or step-up transformer. The internal structure of this product is simple 

and clear, and the wiring is neat and reasonable. High reliability and simple maintenance. Outdoor wall-mounted installation can adapt to various harsh environments. In addition to standard materials and sizes, it can be customized according to user requirements.
