Q: What are the relevant national standards for power equipment?: GB/T10228-2008 GB/T50062-2008 GB/T11032-2000 GB 11032-2010 DL/T613-1997 GB/T17468-1998 GB/T17468-2008 GB/T17211－1998 DL/T804-2002

Q: What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?: Exception: may be a precursor to the accident, has not yet caused the loss, the cause is unknown,Such as the normal operation of the cable overheating, burning plastic taste

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: I would like to ask the power experts, according to the annual additional electricity, installed capacity, how to calculate the amount of the necessary supporting power equipment, etc.?: At least the national research institutions to do, here is about not a conclusion. If such a conclusion, it also belongs to the commercial classified data, not just to show people.

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: The two devices of the power system have those: 4, relay protection and automatic devices, such as relays, automatic devices, used to monitor the operation of a system, rapid response to abnormal and accident, and then acts on the circuit breaker, protection control.5, DC power supply equipment, such as storage batteries, DC generators, silicon rectifier, etc., to provide control and protection of DC power supply and DC load and emergency lighting, etc..6, high frequency wave blocking device.7, since the cast device.

Q: What are the two devices in the power system: Your question is somewhat ambiguous, as I understand the following: the two equipment is a device for the work of the control, protection, monitoring and measurement equipment

Q: The cost calculation of power equipment: Fault and professional people to do the cost of fault handling and so on, there is no fixed standard, depending on the site

Q: Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations? For example, if the provisions of the housing construction warranty, you can check the "construction quality management regulations," but the warranty content of power projects, what information should be checked? Note that the warranty is not repair. Waiting for good people reply, satisfaction and then points.: This is not the regulations of state Power Grid Corp to their line of work area to do some local line area for engineering team to do is sign the contract established general warranty of 1 years seems to include tower structure, grounding resistance, line fitting, a line on what channel estimation problem in within the scope of the contract

Q: What principles should be followed in power equipment maintenance: (2) the maintenance plan shall be arranged according to the unified arrangement of the power grid to improve the coordination and reduce the outage time of the equipment,. Improve operation reliability and equipment availability.
