What is the linkage debugging of diesel generator set?
The linkage debugging of the diesel generator set means that the diesel generator set will be put into trial operation and adjustment test together with other equipment of the project. The generator set is required to start emergency and interlock with the mains electricity within 15 seconds to prevent the unit from running side by side with the mains electricity. It is used as an emergency power supply during fire inspection and acceptance, and is usually used as a backup power supply.
Preparation before linkage debugging:
First of all, make arrangements in advance for the firefighting, elevator, environmental protection, power supply bureau construction team, diesel generator set and other equipment suppliers to be present, and each party is responsible for monitoring the operation of their equipment.
The diesel generator set should check the oil supply system and water cooling system to ensure that the unit has no oil leakage or water leakage. Check the insulation of the connecting bus of the generator set. The grounding is reliable and the phase sequence is correct. Manually start the genset and it runs normally.
Then, notify the elevator construction team, lower the elevator to the ground floor, notify the hydropower construction team and the firefighting construction team, and turn their respective dual power supplies into the switching state.
Main contents of linkage debugging:
Disconnect the mains self-starting genset, and put it into the load one by one; after the standby group runs normally, send the mains power, and disconnect the mains self-starting genset, and run it with load once.
Implementation steps of linkage debugging:
1. The operator opens the respective emergency exit circuit switch separately, and closes the exit switch of the control panel of the generator set, which corresponds to the mains opening and shutting down. At this time, the time from the mains disconnection to the emergency power indicator on the switching screen should be recorded. 15 It is valid within seconds. If the time is exceeded, adjust the time relay and operate it again.
2. Under the instruction of the operator, turn off the emergency lighting, fire station, elevator, disaster prevention box, life pump and fire pump power in sequence, at the same time, observe the operation of the generator set, record the voltage, current, frequency, oil pressure and temperature and Observe the smoke, sound, diesel, and engine oil for leakage.
3. After normal operation of the generator set, restore the city power, stop after 2-3 minutes of operation, and the standby emergency exit return switch is in the closing state.
4. Stop the city power again, start the generator set automatically, record the test standby power switching time, and record the voltage, current, frequency, oil pressure and temperature after meeting the requirements. Each equipment supplier observes the situation of the self-dual power switching box. The switching should be normal.
5. After the diesel generator set has been running for 4 hours, the parameters are normal, that is, the city power is restored, the generator set is automatically stopped, the various data are recorded, and the relevant personnel confirm and sign and archive.
The above is the joint debugging plan of Cummins diesel generator set organized by Yahoo Power. I hope it will be useful to everyone.

7 bars led grow lights is a special lamp to provide light for plants. It usually consists of seven light bulbs, each with a different color and wavelength to simulate the spectrum of natural sunlight. This light fixture is widely used in indoor planting and gardening.
The use of the 7 bars full spectrum led grow lights mainly depends on the following aspects:
1. Light time: plants need light for photosynthesis, and different plants have different needs for light. In general, most plants need 10-12 hours of light per day, so 7 bars plant lights are usually set to work 10-12 hours per day.
2. Light intensity: Plants also have different needs for light intensity. Some plants require more light, while others require less light. 7 bars waterproof led grow lightss usually have an adjustable light intensity function that can be adjusted according to the needs of different plants.
3. Distance and Angle: The distance and Angle between the plant and the 7 bars indoor grow light will also affect the lighting effect. In general, the distance between the plant and the lamp should be kept within an appropriate range to ensure that the plant can fully receive the light.
4. Types of plants: Different plants have different needs for light. Some plants need stronger light to promote growth and flowering, while others have lower light requirements. Therefore, when using the 7 bars indoor grow lights veg, it needs to be adjusted according to the type and needs of the plant.
