① Product Introduction:
Yunhai Zhicheng Electric Intelligent Uninterruptible Power Supply System (ISPS) is an energy-saving and environmentally friendly uninterruptible power supply system. This product effectively solves the technical problem of long EPS conversion time (about 5 seconds) for emergency power supply, and also solves the practical problems of low efficiency, low load rate, and poor environmental adaptability of traditional UPS. It avoids the fire hazard problem caused by the accumulation of a large amount of heat due to long-term online operation of traditional UPS, and provides a truly green, energy-saving, environmentally friendly, and efficient power supply product for the market. The ISPS power system is an energy-saving uninterruptible power supply that operates in a non online mode. Under normal conditions of the power grid, directly output the city grid power supply. When the power grid is abnormal, switch to online operation mode and output the processed city grid power supply. When the power grid returns to normal, restore the city grid power supply. In the event of a power outage due to unforeseen circumstances, output emergency power supply. This type of uninterruptible power supply operates in energy-saving mode for a long time and does not require contactless switches (static switches) to work online. It can achieve high efficiency, environmental protection, eliminate thermal hazards, and extend its lifespan. It has significant advantages over the current popular uninterruptible power supplies (traditional UPS and EPS) in the domestic and international markets.
② Application of ISPS
The ISPS-YH intelligent uninterruptible power supply system is a new energy-saving and environmentally friendly UPS power supply system independently developed and produced by Hebei Yunhai Zhicheng Electric Technology Co., Ltd. This product effectively solves the technical problem of long EPS conversion time (about 3ms) for emergency power supply, and also solves the practical problems of low efficiency, low load rate, and poor environmental adaptability of traditional UPS. It avoids the fire hazard problem caused by the accumulation of a large amount of heat due to long-term online operation of traditional UPS, and provides the market with a truly pollution-free, green, energy-saving, environmentally friendly, and efficient power supply product.
Product advantages
The advantages of this type of ISPS system compared to similar UPS power supply systems are:
1. Three disappearances: ① disappearance of thermal hazards ② disappearance of host harmonics ③ disappearance of additional equipment;
2. Three improvements: ① Improved reliability ② Improved safety ③ Improved safe operating life;
3. Four reductions: ① reduction in host capacity ② reduction in operation and maintenance workload ③ reduction in operating electricity costs ④ reduction in duplicate investment;
4. Energy saving highlights: ① Efficient host saves more than 7% energy ② Air conditioning saves energy (no need to install precision air conditioning in the computer room) ③ Active filters save more than 60% energy (no need to configure active filters).
Energy consumption comparison
project | Traditional UPS | ISPS |
Efficiency | 90% | 97% |
power consumption | Pe·10% | Pe·3% |
kWh | 2.4 degrees/kVA per day 876 degrees/kVA per year | 0.72 degrees/kVA per day 262 degrees/kVA per year |
ancillary facilities | Air conditioning and active filtering are both high energy consuming devices | Backup operation does not require air conditioning or active filtering equipment |
Taking the use of a 100kVA device as an example:
ISPS-YH saves 168 kWh per day and over 60000 kWh per year compared to traditional UPS.
Ancillary facilities: The daily energy consumption of the computer room air conditioning is 50-70 kWh, and at least 50A active filters should be selected for 100kVA. The daily energy consumption is 40 kWh, and the annual energy consumption of the ancillary facilities is 40000 to 50000 kWh.
The use of 100kVA LASPS does not require auxiliary air conditioning or active filtering equipment, resulting in an annual power savings of at least 100000 kWh.
Comparison of Safety
project | Traditional UPS | ISPS |
COOLING SYSTEM | Continuous online cooling requires long-term continuous operation | Backup operation without continuous heat and intermittent work |
Main circuit | Rectification, filtering, and inversion work continuously for a long time | Idle standby safe and reliable |
ancillary facilities | Air conditioning and active filtering require long-term continuous operation | Just simple ventilation is needed |
The long-term continuous operation of components such as rectification, filtering, inverter, isolation transformer, and static switching, as well as capacitors and fans, brings users the cost of uninterrupted protection, which is the worry and running cost of electricity and maintenance fees
Environmental comparison
project | Traditional UPS | ISPS |
Input harmonics | 30% full load harmonic of rectifier | No load operation of rectifier |
Output harmonics | Inverter, static switch full load harmonic 10% | Inverter running without load |
noise | Full load noise 65-70dB | No load noise less than 50dB |
ancillary facilities | Air conditioning and active filtering are both high energy consuming devices | Backup operation does not require air conditioning or active filtering equipment |
In order to solve the problem of harmonic pollution in the power grid caused by rectification of online uninterruptible power supplies, it is necessary to install active filters, power factor compensation devices, increase the oil engine ratio, and increase the household capacity of the power grid; Even if the bypass operates first, the static switch of the bypass generates heat, harmonics, and instability online, and the air conditioning and load side filters in the computer room need to be considered
Comparison of service life
project | Traditional UPS | ISPS |
capacitance | AC and DC filtering work at full load for 2-3 years | Working without load for 8-10 years |
fan | Working 24 hours for 2-3 years | Not working or working intermittently for 8-10 years |
power device | Full load high-frequency switch works for 2-3 years | Working without load for 8-10 years |
The full load current passes through rectifier, filter, inverter, isolation transformer, static switching and other links for a long time. Capacitors, fans and other devices operate continuously for a long time. The damage of small components, especially capacitors and fans, is the killer of the end of the system's life! Even if the bypass operates first, the static switch of the bypass generates heat, harmonics, and instability online, causing frequent damage to the fan and greatly reducing the average time between failures of the system.
