- Q: 1, what are the fire hazards caused by electricity in the server room?2 what are the fire hazards in the server room?
- Two, electrical fire monitoring system should be listed in the department or all the monitoring unit:1 electrical fire monitoring equipment;2 residual current type electric fire monitoring detector;3 temperature measuring electric fire monitoring detector;4 linear temperature fire detector
- Q: What power equipment is needed for the motive,
- As long as the hydraulic pressure machine, bearing induction heater, tooling, assembly line assembly, commissioning test bench. Large parts to a lot, such as various parts of the fixture, the assembly line to the rotary table, lifting operation, pneumatic tools, etc.......
- Q: Under the same voltage level, the rated voltage of the equipment is not exactly the same
- The rated voltage of all kinds of equipment under the same voltage level are not completely the same as normal, different appliances the maximum withstand voltage is different, the design requirements of more electrical and marked a maximum voltage of 240V, some 250V. It is different from the actual working condition under different voltage (whether ideal and safe and reliable)
- Q: What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.
- Such as: 307DL. The device name is on the circuit breaker, numbered 307DL, together they should write off on the line: circuit breaker 307DL
- Q: How to solve the short circuit of emergency communication equipment
- , a number of amateur radio enthusiasts, radio license, the application of their own call sign plate, usually just play the role of decoration,
- Q: Electrical equipment classification
- Mainly there:Equipment for the production and conversion of electrical energy, such as generators, motors, transformers, etc.;Switch on or off circuit breaker, such as circuit breaker, isolating switch, contactor, fuse, etc.
- Q: What are the technical measures to ensure the safety of the power line equipment?
- 1 blackout.2 electrical inspection.3 grounding wire.4 use personal security line.
- Q: How to run a company that operates electric equipment
- Or do not do other electric power equipment, but the company's other power products to pull the business on the line, at the beginning of the sale to the quality of good, and then the price is low, a long time there is profit, customers will have.
- Q: The difference between electric load and power supply capacity
- There is a correlation coefficient between them, the power supply capacity = power load * demand coefficient.
- Q: In power system, the general conditions for the selection of electrical equipment are
- Electrical equipment to be as reliable as possible, must be selected according to the normal working conditions and the short circuit conditions for a variety of checks (such as thermal stability check and dynamic stability check)For some equipment also need to check the special items, such as circuit breakers and fuses to check the ability to break the current, the current limiting reactor to check the normal voltage loss and bus residual voltage, etc..
