Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to an early warning device for centralized control of a power plant. Background Art

[0002] The full name of the centralized control room is the centralized control room. It is the command and control center of the power plant and an important part of the power grid operation. The centralized control station system is established between the dispatching system and the substation. It is an automated system for centralized monitoring and management of multiple unmanned substations. It stands at the level of the local power grid and conducts a higher level of comprehensive control and management of the substations under its jurisdiction. The integrated control operation is mainly for the production and operation management of thermal power plants. Through the effective maintenance of equipment, the safe operability of integrated control is improved. Early warning equipment is usually installed in the centralized control room of the power plant. By setting up monitoring of the electromagnetic field strength in the plant, once the value reaches a certain standard, the early warning device will send out an alarm signal information.

[0003] When optimizing existing early warning equipment for centralized control of power plants, most of the focus is on strengthening the heat dissipation of the early warning equipment. For example, the Chinese utility model patent with application number CN202021672060.5 discloses "A centralized early warning device for thermal power plants that is easy to maintain". By adding a heat dissipation mechanism, the motor inside the starting equipment box can drive the rotating rod to rotate. At this time, the first gear installed on the rotating rod engages the worm to rotate. During the rotation of the worm, it will drive the second gear to rotate. The connecting rod on the second gear follows the rotation, thereby driving the fan blades to rotate. The rotation of the fan blades dissipates the heat of the main body inside the shell, which can effectively dissipate the heat of the early warning device inside the shell, thereby extending the service life of the early warning equipment.

[0004] Although the above-mentioned early warning equipment for power plant centralized control has certain advantages in enhancing the heat dissipation of the equipment, it still has certain disadvantages: the alarm of the early warning equipment is usually an independent body, which is installed on the equipment. The alarm is one of the important components of the early warning device. It is necessary to ensure that the installed alarm is intact at all times. If the alarm fails, it needs to be updated in time. If the disassembly of the alarm on the equipment is more difficult, it is easy to affect other parts during the disassembly and assembly operation, affecting the usability of the equipment. If the alarm is not updated frequently, it is easy for the alarm to fail and there is no alarm sound or the alarm sound is hoarse. Utility Model Content
