What are the requirements for fire standby diesel generator set? when the power supply conditions in the area can not meet the power supply reliability requirements of level 1 load and level 2 load, you should consider setting up fire standby diesel generator set to meet the power supply requirements, but not all units can be used as fire standby diesel generator sets. The self provided emergency generator set shall be equipped with fast automatic starting and power automatic switching device, and have the function of three consecutive self starting. For a class of high-rise buildings, the self starting switching time shall not exceed 30s; for other buildings, manual starting device can also be used when it is difficult to use automatic starting. Generally, the unit should be started by electricity instead of compressed air. The total number of generating units should not be more than 2, and the single unit capacity is generally 800KW or below.
1. Working conditions
It can be operated below 3000 meters above sea level;
The lower limit of ambient temperature is - 15C ° and the upper limit is 40C ° and other environmental units can be selected.
2. Stable performance, strong reliability
The mean time between failures of the unit shall not be less than 2000 hours.
3. Convenient facilities and protection measures for refueling and water adding
The unit is equipped with external refueling system and lock function;
Usually need a large tank, can meet 12-24 hours of operation.
With the wide range of application of diesel generator set, in order to meet the needs of various industries, it can be said that the types of diesel generator set are more and more. The bank is the core of the whole economic lifeline, "electricity" is the basic guarantee for it, so the value created by the bank's generator set is immeasurable. The bank generator set designed and developed by Shanghai yangchai Institute has received good feedback from users. For banks, how to choose diesel generator set? I'll give you some advice. . In other words, the automatic generator set is the choice for the bank. It has four protection functions. The city power has the function of over-voltage, under voltage and missing item detection, and the power generation has the function of over-voltage, under voltage, over frequency and over-current detection. Support a variety of engine types, display the parameters of engine, generator and generator set, and stop protection when the value is unstable. Upgrade the software version, customers can upgrade the firmware version according to their needs to meet the technical requirements. Language: the control system supports 13 languages to meet the needs of customers in different languages.
1. Automatic function. A start cycle includes three starts, and the interval between the two starts is 10-15 seconds. After the unit starts successfully, when the oil pressure reaches the specified value, it should be able to load automatically, and the loading time is usually 10 seconds. After the unit fails to start for three times, it will not start again, and send the start failure alarm signal. If there is a standby unit, the start command should be transmitted to the standby unit. . Normal shutdown steps: cut off the main circuit (disconnect the air switch or switch ATS to the utility side); emergency shutdown steps: immediately cut off the main circuit and fuel oil circuit. The automatic protection unit has low oil pressure, over-voltage, over speed, overload, short-circuit and phase loss protection. The water-cooled unit has the high water temperature protection function, and the air-cooled unit has the high cylinder temperature protection function. 2. Remote monitoring function It can meet the technical requirements of remote monitoring, and has the functions of telemetry, remote signaling and remote control. It can monitor the operation parameters and operation status of the unit in real time. When the unit has abnormal conditions or serious faults, it can automatically alarm the monitoring center and realize remote control of the unit. It can provide standard communication protocol. . Capacity expansion function of parallel unit: two or more three-phase units with identical specifications and models can operate stably in parallel within the range of (20-100)% rated power under rated power factor. In order to improve the reasonable distribution accuracy of active power and reactive power and the stability of operation, the diesel engine governor in the unit is required to have a device to adjust the steady-state speed regulation rate in the range of (2-5)%. The voltage regulating device in the control box (panel) can adjust the steady-state voltage regulation rate within 5%.
