Eps emergency power is rarely seen in our daily life. What we usually see is just ordinary emergency power. The eps emergency power supply is more professional, and it is designed in accordance with emergency lighting requirements for firefighting facilities and major accidents. Since we rarely see it in our daily lives, I believe we don’t know much about EPS emergency power use . Don't worry, here I have gathered a lot of professional knowledge to share with everyone, so that everyone has more understanding of EPS emergency power supply , and know where EPS emergency power use is.

Eps emergency power supply introduction

The eps emergency power supply is a power supply device that is based on the needs of a primary load power supply equipment such as fire fighting facilities, emergency lighting, and accident lighting. The product consists of mutual investment devices, automatic chargers, inverters and battery packs. When the AC grid is normal, the inverter does not work, and the mutual load device supplies power to important loads. When the AC power grid is powered off, the mutual investment device will immediately switch to the inverter power supply. When the grid voltage recovers, the mutual investment device will switch to the AC grid.

Eps emergency power use

Eps emergency power system mainly includes rectifier charger, battery pack, inverter, mutual investment device and system controller. The inverter is the core, usually using DSP or single-chip CPU to control the inverter part SPWM modulation, so that it gets a good AC waveform output; the role of the rectifier charger is to realize the battery pack is timely when the mains input is normal. Charging; The function of the inverter is to convert the DC energy stored in the battery pack into AC output when the utility power is abnormal, and provide stable and continuous power for the load equipment; the mutual investment device ensures that the load is between the utility power and the inverter output. The smooth switching; system controller to control the entire system in real time, and can send a fault alarm signal and receive remote linkage control signal, and through the standard communication interface from the host computer to achieve remote monitoring of the eps system.

In the event of a power outage, the emergency power supply can provide power for various types of electrical equipment on different occasions. It has a wide application range, strong load adaptability, easy installation and high efficiency. The use of centralized power supply emergency power supply can overcome many shortcomings of other power supply methods. Reduce unnecessary waste of electrical energy. In emergency use, lighting and other power consumption places, it has a higher performance-cost ratio than UPS uninterruptible power supply with low conversion efficiency and long-term continuous operation.

EPS emergency power supply is mainly used for emergency power supply that provides centralized power supply for various lighting fixtures (including single-input, single-out metal halide lamps, sodium lamps) in the event of a building fire or other emergency.

  

EPS emergency power brand what

Eps brand is many, according to the user's needs and strength is different, you can choose different manufacturers' products. Similarly, the strength and workmanship of different manufacturers are also very different. According to the user's application requirements and the requirements of the service, different choices can be made. Several major large-scale corporate brands in the country include Founder (Qingdao), Power Source, (Beijing) Shanda, Huatian, and (Shandong) champions.

In order to make the emergency power supply function at a critical time, we usually need to pay attention to the following issues:

1. Maintenance of the site: Check whether the room is ventilated and ventilated. How high is the room temperature? The environment temperature of the battery equipped with the eps is not higher than 30°C. The temperature has a great influence on the service life of the battery. Each battery is increased by 10°C above 25°C. The service life is halved. Conditional units should be equipped with air conditioning. Eps must be away from the fire source and flammable and explosive products, ordinary ordinary debris should not be stacked in the room placed by the eps, not only is not conducive to fire safety but also easily lead to rodent hiding and then bite the cable to cause accidents. During the spring and summer season, the damp air is likely to cause condensation on the inner control circuit board of the EPS, which will cause the control failure of the EPS. Therefore, in the spring and summer season, the interior should be protected against moisture. Indoor dust can not be too dirty, dust is generally positively charged. If there is too much backlog on the EPS board, it may cause the board to malfunction. The placement point of eps can not be too close to the window, to waterproof, rain, and sun.

2. Mains input maintenance: always check whether the mains voltage is normal and whether the zero or fire wire is misaligned, especially if the front end of the EPS is a double-grid mains or a grid with a spare generator set, check the main power supply of the first route frequently. The zero and fire lines of the second standby power supply are the same. If they are found to be misplaced, they must be immediately corrected. Otherwise, EPS failures can easily occur. The user with a lightning arrester at the front end of the eps should regularly check whether the lightning protector and the grounding cable are normal. Lots of rodents should generally be equipped with protective sleeves on the input and output cables.

3, eps output circuit circuit maintenance: According to the status of EPS output circuit breakers to determine whether the output circuit is short circuit, use the clamp flow meter to detect whether the overload circuit, touch the cable by hand to sense the temperature of the cable is abnormal to determine the diameter Is it right or too small?

4. The maintenance of eps itself (eps often occurs).

With the improvement of safety awareness and the application of EPS emergency power supply, as well as the strong promotion and promotion of the domestic fire protection industry and building electrical design industry, the market prospect of EPS will have a very large leap in a few years. Like the fire extinguisher, it is strongly enforced throughout the country.

Editor's summary: The above is about EPS emergency power in the use of the process to pay attention to related issues, I hope everyone in the use of special attention, eps emergency power is used to emergency, in an emergency can help you recover some unnecessary losses Its importance is self-evident. Xiao Bian is here to remind you again, do not put the emergency power on the balcony, long-term sun and rain, accumulation of dust will cause EPS emergency power failure, when the time to use it will not be useful.
