产品简介
Brief introduction to the products

电能计量箱是确保电能计量的准确和可靠,维护供电部门及用电单位的双方经济效益的专用计量设备。产品符合GB16934有关规定和供电部门要求。计量箱适用于户内三相交流50Hz、额定电压380v/220v,额定电流为25-630A的实行力率考核及不实行力率考核的低压供电或高供低计用户的电能计量。  计量箱是为了计量电能所必须的计量器具和辅助设备的总体,包括电能表、计量用电压、电流互感器及其二次回路、电能计量箱。

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.

安装
Installation

计量箱可采用悬挂式或落地式安装。为保证安装质量,悬挂式箱体固定必须内置膨胀螺栓,螺栓尺寸满足安全牢固的要求及户外安装条件。

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.


计量箱内的设备布置事项
Equipment Arrangements Within the Metering Box

直接接入式必须设置进线开关室、计量室和出现开关室;经互感器接入必须设置线开关室、互感器室、计量室和出现开关室。各功能区独立分开。电能表,用电信息采集终端应分别安装在固定夹具、安装架或者栅板上。电能表与电能表之间的水平距离不小于30mm,垂直距离不小于80mm。试验接线盒、电能表、用电信息采集终端与壳体之间距离不低于60mm。电能表正面与观察窗之间的距离应为15-20mm之间。

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.
