Brief introduction to the products

電能計量箱是確保電能計量的準確和可靠,維護供電部門及用電單位的雙方經濟效益的專用計量設備。產品符合GB16934有關規定和供電部門要求。計量箱適用于戶內三相交流50Hz、額定電壓380v/220v,額定電流為25-630A的實行力率考核及不實行力率考核的低壓供電或高供低計用戶的電能計量。  計量箱是為了計量電能所必須的計量器具和輔助設備的總體,包括電能表、計量用電壓、電流互感器及其二次回路、電能計量箱。

Energy metering box is to ensure accurate and reliable energy metering, maintenance of power supply sector and the economic benefits of both units of the special measuring equipment. Products meet the relevant provisions of GB16934 and power sector requirements. Metering box for indoor three-phase AC 50Hz, rated voltage 380v / 220v, rated current of 25-630A the implementation of the rate of assessment and do not implement the power rate assessment of low-voltage power supply or high for the user's energy metering. In this case, Metering box is to measure the electrical energy necessary for measuring instruments and auxiliary equipment in the overall, including the energy meter, metering voltage, current transformer and its secondary circuit, energy metering box.

安裝
Installation

計量箱可采用懸掛式或落地式安裝。為保證安裝質量,懸掛式箱體固定必須內置膨脹螺栓,螺栓尺寸滿足安全牢固的要求及戶外安裝條件。

Metering box can be suspended or floor-mounted. To ensure the quality of the installation, hanging box must be built-in expansion bolts, bolt size to meet the security requirements of solid and outdoor installation conditions.


計量箱內的設備布置事項
Equipment Arrangements Within the Metering Box

直接接入式必須設置進線開關室、計量室和出現開關室;經互感器接入必須設置線開關室、互感器室、計量室和出現開關室。各功能區獨立分開。電能表,用電信息采集終端應分別安裝在固定夾具、安裝架或者柵板上。電能表與電能表之間的水平距離不小于30mm,垂直距離不小于80mm。試驗接線盒、電能表、用電信息采集終端與殼體之間距離不低于60mm。電能表正面與觀察窗之間的距離應為15-20mm之間。

Direct access must be set into the line switch room, metering room and the emergence of the switch room; access to the transformer must be set up line switch room, transformer room, measuring room and the emergence of switch room. The functional areas are separated. Energy meter, power information collection terminal should be installed in the fixed fixture, mounting bracket or grid. The horizontal distance between the electric energy meter and the electric energy meter is not less than 30mm, the vertical distance is not less than 80mm. Test junction box, power meter, power information collection terminal and the distance between the shell of not less than 60mm. The distance between the front of the energy meter and the observation window should be between 15-20mm.
