In recent years, in response to global warming and climate change caused by greenhouse gas emissions，major countries have focused on promoting electric vehicles to replace traditional fuel vehicles. And the construction of charging piles is very important in the promotion of new energy vehicles. Therefore, a large number of charging pile projects have emerged around the world.
As the "dual carbon" goal is proposed and gradually implemented, the development of distributed photovoltaic, which is already showing a good momentum of development, is expected to accelerate substantially.
AC power meter and DC power meter are widely used in EV Charging Station and Charging Pile Market. EV charging piles are found in private residences, commercial buildings.
The IoT platform is suitable for power management. The gateway update data to the platform via MQTT TCP HTTP protocols, and can monitor electrical parameters such as current, voltage, active power, and power factor.
The tower base station monitor and calculate power consumption which includes mains, diesel engines, air-conditioning lighting, switching power supplies, and the DC side needs to achieve -48V operation of base station communication equipment, batteries and other power parameters monitoring and energy metering.
The ARD series of low-voltage motor protectors have protection functions such as overload, phase loss, unbalance, underload, grounding/leakage, and blocking. It can form a motor control protection unit with electrical components such as contactors, motor starters, etc.
ASJ series residual current action relays can be combined with low-voltage circuit breakers or low-voltage contactors to form a combined residual current protection device, which is mainly suitable for AC 50Hz, rated voltage 400V, and below TT and TN system power distribution lines.
The switchgear temperature online monitoring system is based on the 470MHz wireless temperature measurement technology to measure the temperature of the switchgear. It can monitor the temperature of the switchgear including the busbar, upper and lower contacts, cable joints, and the surface of the cabinet in real-time.
Medical isolated power systems equipment is suitable for hospital operating rooms and ICU (CCU) intensive care units and can provide safe, continuous and reliable power supply solutions.
AKH-0.66K series of open-type current transformers are mainly used in the transformation projects of the urban and rural power grids. It is easy to install, does not need to dismantle the bus bar, and can also be operated with electricity.
With the advancement of social production, while commercial users' electricity consumption continues to increase and the requirements for power supply quality continue to increase, there are also a large number of arrears in electricity bills, which greatly increases the operating risks of power supply companies.
