AC power supply system

The Haibo Electric AC power supply system includes AC power cabinets and feeder cabinets, equipped with AC incoming line monitoring modules, which can monitor the voltage, current, and circuit breaker operation status of the incoming circuit and busbar, and achieve automatic switching function of the backup power supply. Set up a monitoring module to collect all information of the AC power supply system and upload it to the main monitor, achieving unmanned operation.

1、 ATS moduleRated voltage: 380/220VNumber of phases: three-phase five wire (A, B, C, N, PE)Frequency: 50HzNeutral grounding method: directly grounded system.The power supply should be dual power supply and lightning protection measures should be taken. The ATS module should be used to achieve automatic switching of two incoming power sources, which can be manually and automatically switched and interlocked. The 0.4kV main wiring is a single busbar connection.The power supply inlet and outlet circuit breakers should use AC dedicated circuit breakers. The overcurrent tripping alarm contacts of all feeder circuit breakers are led to the terminal block, and the feeder circuit breakers should have signal lights indicating the on/off status.Both AC380V AC incoming lines are equipped with digital display three-phase AC voltmeter and three-phase AC ammeter.2、 Electricity meterTwo three-phase four wire fully electronic multifunctional kilowatt hour meters (with an accuracy of 0.5s level) should be installed on the communication screen to measure active and reactive AC energy.3、 Communication monitoring moduleConfigure an AC power monitoring module, receive signals from current transformers, have the function of measuring bus voltage, comprehensively analyze and process various information data, and implement control and management of the entire ATS.
