        電氣成套設備:裝置配電箱的注意事項有哪些?

        發布時間:2021-01-19 來源:http://m.zhaowenjy.com/ 瀏覽量:

        裝置配電箱有相應的規范需求大家遵循,接下來我們電氣成套設備廠家就來說說裝置配電箱的注意事項有哪些。
        The distribution box of the device has the corresponding specifications, which we need to follow. Next, we electrical equipment manufacturers will talk about the precautions of the distribution box of the device.
        (1)施工用電配電體系應設置總配電箱、分配電箱、開關箱,并依照“總-分-開”順序作分級設置,并構成“三級配電”形式。
        (1) The main distribution box, distribution box and switch box shall be set in the power distribution system for construction, and they shall be set according to the sequence of "general - separate - Open" and form the form of "three-level distribution".
        (2)施工用配電體系各配電箱、開關箱的裝置方位要合理。總配電箱要盡量接近變壓器或外電源處,以便電源的引進。分配電箱應盡量裝置在用電設備或負荷相對會集的中心地帶,保證三相負荷保持平衡。開關箱裝置的方位應視現場狀況和工況盡量接近其操控的用電設備。
        (2) The device orientation of each distribution box and switch box in the construction power distribution system shall be reasonable. The general distribution box should be close to the transformer or external power source as far as possible to facilitate the introduction of power supply. The distribution box shall be installed in the central area where the electric equipment or load meet as far as possible to ensure the balance of three-phase load. The orientation of the switch box device shall be close to the electrical equipment controlled by it as far as possible according to the site conditions and working conditions.
        (3)保證臨時用電配電體系三相負荷平衡,施工現場的動力用電和照明用電應構成兩個用電回路,動力配電箱與照明配電箱應該分別設置。
        (3) To ensure the three-phase load balance of the temporary power distribution system, the power and lighting power on the construction site should form two power circuits, and the power distribution box and lighting distribution box should be set separately.
                                      電氣成套設備
        (4)施工現場一切用電設備必須有各自的專用的開關箱。
        (4) All electrical equipment on the construction site must have their own special switch box.
        (5)各級配電箱的箱體和內部設置必須符合規定,開關電器應標明用處,箱體應統一編號。停止使用的配電箱應切斷電源,箱門上鎖。成套電氣廠家固定式配電箱應設置圍欄,并有防雨防砸辦法。
        (5) The box and internal setting of distribution boxes at all levels must comply with safety regulations, the switch appliance shall be marked with use, and the box shall be numbered uniformly. The power supply shall be cut off and the door shall be locked when the distribution box is out of service. The fixed distribution box of complete electrical manufacturer shall be provided with fence and rain proof and smashing proof measures.
        (6)配電箱與配電柜的差異。根據GB/T20641-2006 《低壓成套開關設備和操控設備空殼體的一般要求》
        (6) The difference between distribution box and distribution cabinet. According to GB / t20641-2006 General requirements for empty shells of low voltage switchgear and controlgear assemblies
        配電箱一般是家庭用的,而配電柜則多用在會集供電中,比如說工業用電和修建用電等,配電箱和配電柜都屬于電氣成套設備,配電箱屬于低壓成套設備,配電柜有高壓有低壓。
        The distribution box is generally used in the family, while the distribution cabinet is mostly used in the gathering power supply, such as industrial power and construction power. The distribution box and the distribution cabinet belong to the complete electrical equipment, the distribution box belongs to the complete low-voltage equipment, and the distribution cabinet has high voltage and low voltage.
