The emergency role of emergency standby small generator sets

What kind of requirements do diesel generator sets need to meet as an emergency power supply, generator set manufacturers briefly analyze the following points:

1) Under normal circumstances, the unit should always be in a state of ready to start, when the power supply of the two mains is interrupted, the unit should start immediately, the unit starts the delay time of 0 to 3 seconds (adjustable), and the unit can automatically start the group (a total of three times continuous self-starting function). When the mains power is restored on any road, the diesel generator set should be able to continue to run with load for about 180 seconds (adjustable), until the mains power supply is stable, then switch to the mains power supply with load, and the unit will continue to maintain 0 300 seconds (adjustable) operation and automatically shut down after cooling.

2) There should be an interlocking device between the diesel generator set and the power system to prevent parallel operation.

3) The success rate of diesel generator set self-start is not less than 99%, the unit self-start failure, should be able to send out an alarm signal, the unit should be able to operate on the spot and in the compartment, provide a remote control panel, and the unit self-start signal is provided by the combination of the main inlet voltage relay of the low voltage of the load.

4) Adopt fixed high-speed automatic diesel generator set, and the working mode is standby. The unit should have the characteristics of fast starting, strong ability to withstand sudden load, reliable operation, good speed regulation, low failure rate, low noise, low vibration, low pollution, small size, light weight, and convenient maintenance.

5) The important components of the unit, such as engine, generator, generator controller, etc., should be provided by internationally renowned manufacturers with reliable quality and advanced technology, and the origin, manufacturer and corresponding technical specifications should be provided when bidding.

6) The unit should provide an outgoing power distribution cabinet on site, and configure a frame removable circuit breaker. The generator shall be equipped with short circuit, overload, grounding, overvoltage, undervoltage, and reverse power fault protection devices. The average time between failures of the unit is 10,000h.

7) The unit should have an independent fuel storage room to ensure a certain amount of fuel and fire safety measures.

Diesel generator sets have always been the first choice for emergency power supply, and the advantages of diesel generator sets as emergency power supply can be explained from five aspects. (For reference only: Yanan Diesel Generator Answer: 4000-080-999).

1) High power, stable voltage, fuel economy, high thermal efficiency, when the working conditions change, the fuel consumption rate curve changes relatively flat, and it is economical under low load (2) Reliable and durable. Because there is no ignition system, the fault is low (3) wide range of use (4) low harmful emissions (5) good fire safety, very suitable for use in hospitals and other places with high electricity requirements, in contrast, although the gasoline generator is small in size and easy to carry, but the power is small, the voltage is unstable, and the fuel consumption is high, which is more suitable for household electricity, small-scale electricity and other places with general electricity requirements.

Yanan motor technician tips: with the development of China's industrial construction, diesel generator sets are widely used in finance, post and telecommunications, petrochemical, metallurgy, transportation and other industries, excellent product quality and reliable performance, the structure of supporting equipment is very compact, flexible installation location, most of the domestic cities of high electricity places generally choose to use diesel generators as backup power supply, I believe that with the progress of scientific research and technology, the future diesel generators will be widely used in various industries with high electricity consumption, and have made great progress.

Because power outages are not allowed in these areas, emergency generator sets are widely used as backup power sources in these units. With the continuous improvement of technology: such as accident lighting, the quality and power generation effect of diesel generator sets are the most fundamental, escape indicators, aviation obstacles and guide lights, fire hydrant pumps, fire alarm devices, etc.

In the event of a power outage, business will be affected. The emergency diesel generator set can play a role in maintaining normal operation after the mains power is cut off, and the emergency generator set will generally be in the medical treatment. Fujian Yanan generator set is a famous brand product in China.

The main thing is that the technology is in place, and the emergency diesel generator set can ensure the normal operation of the fire escape, and if there is a power outage in a large medical unit, it will also lead to life danger. Especially emergency generator sets. The emergency diesel generator set can keep the emergency lighting equipment working during the mains power outage, such as a gas station, and can accurately generate electricity for people's lives; You can mention **urgent lighting:

Certain data computers and network equipment require continuous power supply to maintain normal operation, such as fire elevators, work and even life safety. Therefore: once a dangerous situation occurs, the Yanan generator set ** is also constantly undulating, commercial, and rolling shutters.

Yanan diesel generator** is also more affordable, supermarkets, etc.; It can be used as an emergency network device and computer equipment. It can be used as an emergency power generation device. In order to avoid the loss of personnel and property caused by power outages of lighting equipment, the impact of market effects, and finance.

Individual departments with good quality and advanced technology, transportation and other industries make backup generator sets for use, evacuation and escape sign lighting, resulting in economic losses, the use effect and life can reach perfection, smoke exhaust fans, and emergency diesel generator sets are necessary to ensure the smooth passage of fire escapes.

Two features of the work of diesel generators for emergency use.

1. For emergency use, the continuous working time is not long, and generally only needs to continue to run for a few hours (12h).

2. As a backup, the emergency diesel generator set is usually in a state of shutdown and waiting, only when the main power supply is all out of power, the emergency diesel generator set will start to run to supply the emergency power load, and when the main power supply returns to normal, then switch and shut down.

When choosing an emergency diesel generator, the user should choose what configuration and how much power the unit should choose according to the specific work needs.

Chip semiconductors, municipal, mining, petrochemical, power plants, data centers, finance, communications, hotels, medical, construction, national defense and military and other fields, can be used as backup power supply, emergency power supply, can also be used as the main power supply.

Emergency generator sets are generally used as backup generator sets in individual departments of medical, commercial, financial, transportation and other industries. Because blackouts are not allowed in these areas. Once the power outage will affect the business, cause economic losses, and in large medical units, if the power outage can lead to life-threatening.

Therefore, emergency generator sets are widely used as standby power sources in these units. Yuchai generator set is a famous brand product in China. High quality and advanced technology.

Yuchai diesel generators** are also more affordable. The main thing is that the technology is in place, and the use effect and life can be perfect. In particular, the emergency generator set can accurately generate electricity to provide protection for people's life, work and even life safety.

It can be used as emergency power generation equipment: in the event of a dangerous situation, the emergency diesel generator set can ensure the normal operation of the fire channel, such as fire elevator, escape indicator, fire hydrant pump, smoke exhaust fan, roller shutter door, fire alarm device, etc., emergency diesel generator set is a necessity to ensure the smooth operation of the fire channel;

Can be used as emergency network equipment and computer equipment: Some data computers and network equipment need continuous power supply to maintain normal operation, such as gas stations, supermarkets, etc. The emergency diesel generator set can play a role in maintaining normal operation after the mains power is cut off;

It can be mentioned that there is a lack of emergency lighting: such as accident lighting, evacuation and escape sign lighting, aviation obstacles and guiding lights. The emergency diesel generator set can keep the emergency lighting equipment working during the mains power outage.

To avoid the loss of people and property due to power outages of lighting equipment.

With the continuous improvement of technology, the impact of the market effect, Yuchai generator set Qiaotong is also constantly ups and downs, we can not only consider the market when buying Yuchai generator set, the quality and power generation effect of diesel generator set is the most fundamental.

The control system of the emergency diesel generator set The control of the emergency diesel generator set should have a fast self-starting and automatic input device. When the main power supply fails to cut off, the emergency unit should be able to quickly start and restore the power supply, and the allowable power failure time of the primary load is from more than ten seconds to dozens of seconds, which should be determined according to the specific situation. When the main power supply of an important project is cut off, there must first be a confirmation time of 3 5s to avoid the instantaneous voltage drop and the time when the municipal power grid closes or the standby power supply is automatically put in, and then the command to start the emergency unit is issued.

It takes a while from the time the command is issued, the unit starts to start, and the speed is increased to the load that can be carried by the force. Large and medium-sized diesel generator sets also need pre-lubrication and warm-up processes, so that the oil (oil) pressure of the full loss system, the oil (oil) temperature of the total loss system and the cooling water temperature during emergency loading meet the requirements of the technical conditions of the product; The pre-lubrication and warm-up process of the unit can be carried out in advance according to different conditions. For example, emergency units such as post and telecommunications and military communications, important foreign affairs activities in large hotels, large-scale mass activities in public buildings at night, and important surgical operations in hospitals should be in a state of pre-lubrication and warm-up at ordinary times, so as to start quickly at any time and shorten the time of failure and power outage as much as possible.
