Nowadays, people's living standards are improving and their electricity consumption is also increasing. How to better understand their own electricity consumption? It is necessary to install an electric meter to know the power consumption, but the electric meter can not be installed casually. A reasonable and safe installation is the most important! We all know that everyone has his own home, so does the electric meter! The meter box (split meter ready board box) is the warm "home" of the meter! Today, let's know where the meter box (split meter ready board box) must be installed?
1. In principle, the electric energy metering assembly for trade settlement shall be set at the property boundary of power supply and consumption facilities; At the other end of the power generation enterprise's network line, the interconnection line between the power grid operation enterprises and the dedicated power supply line, the assessment electric energy metering assembly shall be set.
2. The electrical energy metering assembly for Class I, II and III trade settlement shall be equipped with special voltage and current transformers or special secondary windings for metering according to the metering point. The special voltage and current transformer or special secondary winding and its secondary circuit for electric energy metering shall not be connected to equipment unrelated to electric energy metering.
3. The electric energy metering assembly for measuring the online trade settlement energy of generating units with a unit capacity of 100MW or more and the electric energy metering assembly for purchasing and selling electricity between power grid operating enterprises should be equipped with two sets of active energy meters with the same accuracy grade.
4. The secondary circuit of the voltage transformer in the electric energy metering assembly for trade settlement above 35kV shall not be equipped with the isolating switch auxiliary contact, but the fuse can be installed; The secondary circuit of voltage transformer in the electric energy metering assembly for trade settlement of 35kV and below shall not be equipped with isolating and disconnecting auxiliary contacts and fuses.
5. The power metering assembly for trade settlement installed at the user's place, and the power supply users with voltage of 35kV and below shall be equipped with the power metering cabinet or power metering box of the same national standard; Users of kVA20 voltage power supply should be equipped with electric energy metering cabinet or electric energy metering box of the same national standard.
