需要根据具体情况进行分析。
It needs to be analyzed according to the specific situation.
1、只要用电时需要计量，就需要安装计量箱。以前企业用电时多采用低压计量再加线路损耗的方式来计算总用电量，现在多采用在进线侧安装高压计量来计算总用电量，优点是避免了损耗厘定不准确。至于到底采用高压计量还是低压计量要看供电部门的具体规定。
1. As long as the power consumption needs to be measured, the measuring box needs to be installed. In the past, enterprises used low-voltage measurement and line loss to calculate the total power consumption. Now, high-voltage measurement is installed on the line side to calculate the total power consumption, which has the advantage of avoiding inaccurate loss determination. Whether to use high-voltage measurement or low-voltage measurement depends on the specific provisions of the power supply department.
2、高压计量箱只有安装到线路中才能实现计量作用，需要具备电力安装资质的人员根据安装规程进行安装使用。
2. High-voltage metering box can only be installed in the line to achieve the metering function. It needs the personnel qualified for power installation to install and use according to the installation rules.
