- Q: What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?
- Accident: has occurred, resulting in loss of damage,Such as short circuit arc circuit breaker tripping, burning, scrap.
- Q: In what way is it confirmed that the destroyer is an electrical device? Identification or what.
- Electricity has been used, but due to the lack of dry season or lack of electricity and other reasons, and the suspension of power supply lines, should still be considered to be in use. The behavior of the people to cut such lines in the cut, if a crime, shall be held criminally responsible for the destruction of electric power equipment.
- Q: Under the same voltage level, the rated voltage of the equipment is not exactly the same
- And some appliances have no effect. For example: switching power supply, it can work in a wide range of voltage, the output voltage remains unchanged. It should be noted that, as long as the manufacturers in the normal operating voltage range, generally will not cause the state of work and security issues, can be assured that the use of.
- Q: All I know is a generator, a transformer. I also want to fully understand the power system related to the equipment, from power generation to end users (enterprises, factories, they will design the equipment, production equipment is not to say, but they will be transferred to the electricity, in use is the processing equipment, such as transformer, I only know this involved) equipment, detailed list, thank you ah
- Divided into primary equipment and two equipmentOnce the equipment is responsible for the transmission of electrical energy, the two equipment is responsible for monitoring and protection of primary equipment.
- Q: On the safety hazards of electric equipment safety
- 4 where the demolition, the power line protection zones of overweight, lifting, drilling, piling, scaffolding and other construction work, it shall be permitted by the power supply departments, take appropriate safety measures, and can work in the power supply department under the supervision of professional staff.5 prohibit the installation of electric power facilities within the range of 500 meters to carry out blasting operations, fireworks, etc..6 prohibit fishing in the power line protection zone, in case of personal electric shock accident.7 ban on power line protection zones, such as various types of debris piled hay straw, especially prohibit piling flammable and explosive materials.
- Q: In order to ensure the normal operation of the power system and equipment to achieve a grounding
- 4) repeat grounding: in the low voltage three-phase four wire system (380V/220V), which is directly grounded in the neutral point, in addition to the working connection at the power supply, it is necessary to re connect the ground at the other place of the zero line. To ensure the safety and reliability of the zero line. It is simply to say that one or more points on the zero line are grounded again.
- Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator
- The power supply in the power system is a three-phase sine alternating current generated by the generator, in which there are two kinds of electric power.
- Q: Withstand voltage test, power equipment insulation unqualified reasons?
- Test methods and voltage measurement methods are not correct. For example, when the transformer is tested, the non - Test winding is not connected to the ground, and the non - tested winding may be discharged to the ground. For example, the test of large capacity test, the voltage is still on the low side of the measurement, due to the capacitive effect, the actual increase in the voltage on the test sample over the test voltage, resulting in the breakdown of the subject matter, misjudgment is not qualified.
- Q: What is the power plant
- Is to do the preparation of electricity ahTransformer transformerSmall to power switch, etc.
- Q: What is the redundancy of electrical equipment
- Redundancy is a part of the system that is repeatedly configured. When the system is in trouble, the redundant components are involved in the work of the faulty components, thereby reducing the failure time of the system.
