7KW diesel alternator When AC is synchronized Generator Set When the power system fails (such as short circuit or open circuit in the power grid), the neutral point of the distribution system will shift. At this time, the neutral point grounding resistance will output the forced grounding of the distribution system neutral point, and limit its fault current, so that the power system has time to detect, diagnose, protect and switch, thus avoiding possible damage to lines or equipment. Since the neutral point resistance can absorb a large amount of resonance energy resistor In the grounding mode The resonance overvoltage of the system is eliminated. The current of the neutral point grounding resistance is very small when the power transmission and distribution system works normally, but when the power system fails, the current flowing through the neutral point grounding resistance is very large and the time is very short. It is usually used for short-time operation.
7KW diesel generator 1. Do not use the generator indoors or in supermarkets. 2. You can directly connect the motor switch Connect to the circuit. 3. Shut down the machine when filling fuel. Fire and spilling of fuel are strictly prohibited.
Inspection before operation: 1. Place the unit horizontally to check the oil level. The oil level shall be subject to the oil port. Ordinary steam engine oil can be used as the oil. Of course, better oil will be better.
2. Use 90 # or above, add according to the time of use, add high pressure heater to the shoulder of the mailbox filter, install it, and cover the fuel tank cap. 3. Check all connecting parts door If there is looseness, the unit can be started only after all parts of the unit are normal.
It is also important to say that the age of the generator is the cumulative operating time rather than the old or new degree. The generator is different from other machines. If it is used as a standby machine, it may not operate for 10 years or 8 years. If as Power use, that is, 24-hour continuous operation. The service life of the generator is generally long, and the machine that has been running continuously for 2 years is still OK. However, there are great differences between a new machine and an old machine in failure rate, oil consumption, noise, exhaust emissions, etc., so we should try to choose a new machine. The above three basic points need attention when choosing a generator. I hope they can help you. I wish you can choose a suitable generator. We sincerely hope you can choose our Daze Power.
