Product Requirements and Challenges
1. Working Conditions
The unit can work reliably under the following conditions, output power, and can work continuously for 24 hours at rated power output mode (including overloading 10% every 12 hours for 1 hour) The altitude shall not exceed 1000 meters The lower limit of the ambient temperature is -15C ° C, and the upper limit is 40C ° C. Other environmental units can be selected
2、 Low work noise
Ultra low noise ensures that hospital doctors can work with peace of mind in a sufficiently quiet environment, especially to ensure that surgical activities can be carried out quietly in the operating room, while also ensuring that patients have a quiet resting and recuperation environment
3、 In the event of the following faults in the main and necessary protective devices, the unit will automatically shut down and issue corresponding signals: low oil pressure, high water temperature, overspeed, unsuccessful start, etc The starting mode of the unit is selected as automatic starting mode. The crew must have AMF (Automatic Mains Failure) function and be equipped with ATS to achieve fully automatic start-up. When there is a power outage, the delay in starting time is less than or equal to; After 5 seconds (adjustable), the unit can automatically start (with a total of three consecutive automatic start functions), and the full negative switching time between mains power and the unit is less than or equal to; 10 seconds, the time required to fully meet the load input is less than 12 seconds. After the mains power is restored, the unit will maintain 0-300 seconds of operation and cool down (adjustable) before automatically shutting down
4、 Stable performance and strong reliability. The average fault interval of the unit shall not be less than 2000 hours In terms of technical performance, the no-load voltage setting range of the unit is 95-105% of the rated voltage
Solution
A high-performance and stable generator set, designed with low noise, equipped with a PLC-5220 control system with AMF function, connected to ATS to ensure that the hospital can immediately provide power in the event of a power outage from the main power supply. Stable, low-noise, engine power that meets European and American emission standards, as well as AMF functionality and ATS equipment, meet the special requirements of hospitals. By equipping with RS232 or RS485/422 communication interfaces, it can be connected to a computer for remote monitoring, remote control, remote signaling, and telemetry, achieving full automation and unmanned operation
Advantages
A complete set of products and solutions are provided, reducing users' requirements for technical mastery and making unit use and maintenance simpler and easier The control system has AMF function, which can automatically start and has multiple automatic shutdown and alarm functions under monitoring Optional ATS, small units can choose built-in ATS Ultra low noise power generation, the noise level of units below 30KVA is below 7 meters and 60dB (A) Stable performance, with an average fault interval of no less than 2000 hours for the unit The unit has a small volume and can be equipped with some devices to meet the operational requirements in cold and high temperature regions Customized design and development can be provided for special needs of some customers.
