Working principle of intelligent charging box type substation
Source:
The working principle of the intelligent charging box type substation is based on the principle of electromagnetic induction, and the conversion and distribution of electrical energy are achieved through integrated power equipment.
Working principle
Electricity reception and conversion
High voltage electrical energy (usually 10kV) is converted into low-voltage electrical energy (380V or 220V) suitable for charging stations through transformers, while achieving voltage level adaptation.
Equipment collaborative control
Integrated high voltage switchgear controls the on/off of high voltage circuits, low voltage switchgear protects low voltage circuits from overload, short circuit and other faults, energy metering equipment records electricity consumption, and reactive power compensation devices optimize the power factor of the power grid.
Intelligent management
Equipped with a microcomputer integrated automation system, it can achieve telemetry, remote signaling, remote control, and remote adjustment ("four remote" functions), support unmanned mode, and have humidity, temperature monitoring, and smoke alarm functions.
Core strengths
Efficient and stable: The factory prefabricated modular design shortens the on-site installation cycle to 5-8 days, adapting to compact urban spaces.
Safe and reliable: The fully enclosed structure prevents the risk of electric shock, and the intelligent control system quickly responds to faults and cuts off power.
Flexible adaptation: Supports customized design to meet the power needs of different scenarios, such as commercial areas, residential areas, and highway service areas.
