- Q: What are the characteristics of the grounding of the power system and equipment?
- According to the use and nature of grounding, it can be divided into "working grounding" and "security grounding".
- Q: We are a manufacturer of intelligent switching equipment manufacturers to bid in the power grid to say what is the first access to what the Department
- Hello: * power equipment network license, refers to the equipment after a rigorous examination of the administrative departments of electric power, can be put into the power grid stability [], [], no adverse effects on the power grid [] reliable products. From the technical point of view, the detection of more projects, more stringent requirements, you can apply to the local power management department, the network testing, examination and approval procedures, qualified to participate in bidding operations.
- Q: On the nameplate of the electrical equipment, what does ith UE ie mean?
- Electrical equipment (Electrical Equipment) is in the power system of generators, transformers, power lines, circuit breakers and other equipment collectively.
- Q: 1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?
- The common measurement and control cabinet are generally some common control signals such as AC / DC screen, knife position, device power loss and telemetry some voltage and current value, there are no specific remote control, measurement and control device of equipment access to public control
- Q: What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!
- The necessity of power equipment testingPower equipment is the hub and channel in the transmission and distribution network, in the course of the use of equipment will be aging, disrepair, hidden trouble, etc.. However, these situations can not be ruled out by the eyes of the people, the staff of the experience, it is necessary to detect the special power equipment to check out these security risks and the organization of human resources in a timely manner to exclude.In the operation of electric power, the safety of electric power has always been a chord of the electric power. Power equipment testing is actually played a role in prevention and detection of hidden dangers. So it is very important to detect the electric equipment (i.e., the preventive test of electric equipment).
- Q: In order to obtain the qualification test of power equipment, the company needs to have a hard condition
- The office, factory are required not less than the number of square and so on, the registered capital of the company scale is also in short, very troublesome, a pile of data. To prepare documents and construction safety license corresponding to the handle. In a word, money, have a lot of money money is easy,
- Q: How long has the power of power electronic equipment delivered water
- ; equipment (mainly separator population) and pipeline (mainly elbow) wear faster, if the design, construction or improper operation, is easy to cause material deposition, so that the conveying jam, interrupt; transportation should not be high humidity, viscous or easily broken material etc..
- Q: Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- A device with a motor can be called a rotating device. Power system mainly refers to the generator, motor
- 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: Pre checking and checking of goods in power system
- Pilot: the full name of the preventive test, generally in terms of a power system equipment, in order to find in the operation of equipment problems, to prevent the occurrence of accidents or damage to equipment, equipment for inspection, testing or monitoring, including oil sampling test or gas samples. The preventive test is the operation of power equipment and to maintain an important aspect of the work
