How much do you know about meter box (ready board)?

1. Concept of meter box (ready board):

A total circuit distribution box for all users;

2. Working principle

The meter box (ready board) is used to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in an enclosed or semi enclosed metal cabinet or screen to form a low-voltage power distribution device according to the electrical wiring requirements. During normal operation, the circuit can be switched on or off with the help of manual or automatic switches; In case of failure or abnormal operation, the circuit or alarm can be cut off with the help of protective appliances, and various parameters in operation can be displayed by measuring instruments. Some electrical parameters can also be adjusted, and the deviation from the normal working state can be prompted or signaled, which is commonly used in each power generation, distribution and substation;

3. Main purpose

It is convenient for management and maintenance in case of circuit failure. Moreover, it is convenient for power cut and transmission, and plays the role of measuring and judging power cut and transmission; The meter box (ready board), distribution cabinet, switchboard, power distribution certificate, etc. are complete sets of devices for centralized installation of switches, instruments, etc;

4. Classification

1) According to the quantity and specifications of installed electric energy meters, they are divided into five categories: single-phase single meter metering box, three-phase single meter metering box, multi meter single-phase electric energy meter metering box, multi meter three-phase electric energy meter metering box and transformer type metering box;

2) It is divided into metal measuring box and plastic measuring box according to the manufacturing materials;

3) According to the installation environment, it can be divided into indoor and outdoor metering boxes;

4) According to the installation mode, the installation structure type of metering box: suspended meter box, embedded meter box, floor type meter box, pole type meter box;
