Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, and in particular to a fast-replaceable unit-type diesel generator set control cabinet and a fault detection method. Background Art

[0002] The power system is an important material basis for the development of the national economy and the survival of human society, and is usually composed of power generation, transmission, transformation, distribution, etc. Among them, power generation is the primary link and key foundation for ensuring the supply of electric energy.

[0003] At present, national standards and specifications require that the reliability of general urban power supply networks should be greater than 99.9%, and the reliability of power supply in large urban centers should be greater than 99.99%. In some important national defense projects and key civilian facilities such as hospitals, transportation, and communications, the power supply reliability of the distribution network is required to reach 99.999% or even higher. Once the city power supply is interrupted, it is particularly important for diesel generator sets to improve the reliability of power supply in the power system as an emergency power supply. They must be started immediately to complete the power supply, and the shorter the interruption time, the better. JGJ312-2013 "Electrical Design Specifications for Medical Buildings" stipulates that the standby diesel generator set should be able to reach a stable state within 15S and supply power to the specified power consumption.

[0004] Diesel generator sets usually consist of three parts: diesel engine, generator and unit control cabinet. In order to improve the reliability of power supply, they are often operated in the working mode of "one in use and one in reserve" or "two in use and one in reserve". Among them, the unit control cabinet has the highest failure rate, the greatest difficulty in short-term maintenance, and the most direct impact on the rapid restoration of power supply. The automated diesel generator unit control cabinet consists of multiple generator control panels, parallel panels and switching panels. Among them: the generator control panel is used to adjust the unit operating status and power generation parameters of a single generator set; the parallel panel controls the parallel or de-parallel operation of the unit according to the user's load conditions; the switching panel selects one of the two between the mains and the unit power supply, and the mains power supply is preferred. When the mains power supply is interrupted, the unit busbar is automatically closed for power supply.

[0005] Once a diesel generator set control cabinet fails, causing a power outage, the operation and maintenance personnel are often required to locate the fault point and eliminate it within seconds, which places extremely high demands on the equipment operators. Summary of the invention
