With the continuous breakthrough of renewable energy technologies, new green energy such as photovoltaic and wind power has become an important supplement to electric power supply. Electric vehicles are increasingly favored due to their zero-pollution emissions, and charging stations responsible for supplying electric vehicles are used as electric vehicles. With an increasing number of automotive affiliated facilities entering peopleâ€™s field of vision, the safety of its operations has also been receiving increasing attention. With years of in-depth development of smart grid customer-end products, Ancorui Electric has introduced electrical suitable for electric vehicle charging stations. Safety, energy metering product application program.
First, AC charging station product plan:
AC charging piles generally have a power of about 7 kW. The total line return is equipped with a power quality analyzer to monitor the power quality of the entire charging pile power supply loop. The incoming circuit is equipped with an electrical fire monitoring device, a charge management controller, which is responsible for charge and charge control, and a single-phase rail type AC power meter for charging energy metering. The power data is read by the charge management controller through the RS485 communication port; The line side is equipped with a leakage protection circuit breaker; the charge side is equipped with a live operation miniature circuit breaker.

Second, small car DC charging pile
The small-sized DC charging piles generally have a power of about 12 kW. A total power return loop configures a power quality analyzer to monitor the power quality of the power supply loop of the entire charging pile. Into the line circuit at the same time set up electrical fire monitoring devices, access to fire monitoring back-end system. The charging circuit adopts three-phase power supply, and its input line is equipped with a miniature circuit breaker with leakage protection. The charge management controller is responsible for the external human-machine interface, charge control, reading the power data of the DC energy meter, controlling the switching of the DC charging output circuit breaker, and the like. Built-in DC energy meter with external Hall sensor or shunt to achieve the measurement of charging power, Hall because of its non-contact measurement and shunt compared to, can have a higher installation convenience and electrical safety performance.

Third, electric bus charging pile
The large-scale electric bus DC charging pile has a relatively large power, about 200kW, and the power line quality analyzer is configured in the total line circuit to monitor the power quality of the entire charging pile power supply loop. At the same time set up the electrical fire monitoring device, the charging circuit adopts three-phase power supply, and its incoming line adopts AC molded case circuit breaker. The three-phase main circuit configures the residual current relay and provides indirect contact protection. Due to the large power consumption of such charging piles, it is recommended to configure a rail-type energy meter in its three-phase AC circuit for the measurement of total electrical energy, and to monitor the operating efficiency of the entire charging station with a DC power meter. The charge management controller is responsible for the external human-machine interface, charge control, reading the power data of the DC energy meter, controlling the switching of the DC charging output circuit breaker, and the like.
3.1 Product Selection
CONNECT rendering Raw Material Handling Equipment including the raw material hopper, silo, large bones or animals crusher, feature water squeez machine to remove the water which come from slaughterhouse, the feature belt conveyor which for feeding the raw material into digestor. The small capacity Rendering Plant is working with the raw material feeding conveyor to digest to realize the semi-automatic working process for feeding. The large capacity rendering plant need working with the raw matereial hopper, feeding pump system to form the fully automatic working which not only saving labors cost but also match the large working capacity.
