Basic Knowledge of Keeping The Diesel Generator Room Clean 2

This article continues to popularize basic knowledge such as keeping the diesel generator room clean, power factor, and the conditions for parallel use.

What problems should be noted when using a generator set with an ungrounded neutral point?

Answer: The neutral wire may be energized because the capacitive voltage between the live wire and the neutral point cannot be eliminated. Operators must regard the neutral wire as a live conductor.

How should the power of a UPS be matched with that of a diesel generator to ensure stable output of the UPS?

Answer: (1) UPS is generally expressed in apparent power KVA. First, multiply it by 0.8 to convert it to the unit KW, which is consistent with the active power of the generator.

(2) If an ordinary generator is used, multiply the active power of the UPS by 2 to determine the power of the generator to be equipped, that is, the power of the generator is twice that of the UPS.

(3) If a generator with PMG (permanent magnet generator excitation) is used, multiply the power of the UPS by 1.2 to determine the power of the generator, that is, the power of the generator is 1.2 times that of the UPS.

Can electronic or electrical components marked with a withstand voltage of 500V be used in the control cabinet of a diesel generator?

Answer: No. Because the voltage marked on the diesel generator set, 400/230V, is the effective voltage. Its peak voltage is 1.414 times the effective voltage. That is, the peak voltage of the diesel generator is Umax = 566/325V.

To which level of energy does electrical energy belong? What kind of energy is alternating current converted from, and what kind of energy is direct current converted from? What are their characteristics?

Answer: Electrical energy belongs to secondary energy. Alternating current is converted from mechanical energy, and direct current is converted from chemical energy. The characteristics of alternating current are that its direction and magnitude change continuously. The direction of direct current is constant, and its magnitude changes continuously. Electrical energy can only be used as it is generated and cannot be stored.

What does the general symbol GF of domestic generator sets represent?

Answer: It represents two meanings: (1) Power frequency generator sets, that is, generator sets suitable for the general frequency of 50HZ in China; (2) Domestic generator sets.

I hope everyone has learned this basic knowledge about diesel generator set failures. In fact, it is not difficult to master this basic knowledge. It is nothing more than some basic operation and management issues. If you want to be thoroughly proficient, you can only achieve it through continuous learning, thinking, and perseverance. For ordinary management users, there is no need to be extremely proficient. Just understanding some necessary maintenance knowledge is sufficient. When a generator set malfunctions, it is better to contact a professional diesel generator manufacturer.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to [email protected] we will pay highly attention on your question.
