Types of Electrical panels
High and low voltage power distribution cabinets are power distribution equipment used for power distribution,
control, metering and connecting cables in power supply systems.
Generally, power supply bureaus and substations use high voltage switch cabinets,
and then step down the low voltage side through the transformer Lead to low-voltage distribution cabinet.
The low-voltage electrical panels/ power distribution cabinet reaches the design function requirements by assembling some protection devices
such as switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, etc. into the power distribution board,
control box, and switch box of each power consumption.
Equipment of power distribution unit. Commonly known as:
high and low voltage switchgear or high and low voltage electrical equipment.
Types of Electrical panels boards
High-voltage inlet panels, metering panels, high-voltage outlet panels, low-voltage inlet panels, capacitor cabinets, and low-voltage outlet panels.
These power distribution panels are the conventional configuration of the power distribution room.
Both high voltage and low voltage are combined according to certain functions.
(1) High-voltage inlet panels
It is a high-voltage cabinet that disconnects the high-voltage inlet power supply.
In fact, it is not a real inlet cabinet. The inlet is generally not connected to this cabinet, but connected to the isolation cabinet, but it has a broken circuit.
The device (vacuum) can disconnect the incoming power, so it is called the incoming cabinet.
(2) Metering panels
As the name implies, it is used to install an electricity meter, a cabinet that accurately measures how much electricity you use.
The cabinet has no big components except PT and CT.
(3) High-voltage outlet panels
His role is to distribute and transmit electrical energy.
He usually carries a transformer or high-voltage electrical equipment (motor) and high-voltage compensation equipment.
(4) Low-voltage incoming panels
It is generally the first cabinet coming down from the transformer, also known as the low main cabinet.
which is used to control all the electrical equipment below.
His main switch is generally a frame circuit breaker.
(5) Capacitor cabinet/capacitor panels
His role is to compensate for the quality of electricity consumption and improve the power factor.
(6) Low-voltage outlet panels
Its role is to distribute and transmit electrical energy.
Unlike high-voltage, it is basically directly to the electrical equipment.
The switch is usually a molded case circuit breaker.
