1,Brief Introduction to Product
MRD-FD type neutral ground resistor cabinet is complete equipment specially used by generators in power plant which adopts high-resistance grounding for neutral. The voltage grade for generator mainly ranges from 6kv to 20kv. When one point of the stator grounds, the device is able to limit the grounding current at a reasonable value, and effectively restraint arc flash transient overvoltage associated with single-phase grounding.
1,Applies to indoors.
2,Ambient temperature: between -40 and +40 centigrade.
3,The altitude shall not exceed 3000m.
4,Relative humidity be or lower than 95%(25 centigrade)
5,Power grid frequency:58-62Hz (60Hz System), 48-52Hz (50Hz System)
6,The air at the installation site shall be free from chemical corrosion, vapour or explosive dust
2.1 Parameters of Grounding Transformer
Insulation class：H
Cooling：AN
Protection Level: for paper-insulated dry type grounding transformer, the PI is divided into IP00 (no enclosure), IP20, and IP23 (with enclosure) .
Insulation level, impedance voltage on-load loss and no-load loss are according to relevant national standards.
Insulation resistance testing: high voltage-low voltage and to earth≥300MΩ，and low voltage-earth≥100MΩ.
- Q: Maintenance of electrical equipment, security measures to ensure that what
- 6, is strictly prohibited live moving, demolition, relocation and maintenance of electrical equipment and lines.7, all cables are not allowed to have a fire joint, tear, leakage phenomenon, such as cable break, should be used with equal effectiveness hot cold patch, allowed to send electricity.8, all electrical equipment is strictly prohibited fire operation, maintenance of electric equipment, should be properly protected, not smashed on the explosion-proof surface, ensure the explosion-proof surface finish and explosion-proof performance, and paint oil or vaseline to evenly.9, timely maintenance control, switch control must hit the "off" position, set off switch handle, and remove the clutch.
- Q: Electric power automation equipment
- Construction and transformation of rural power grids, power plants, power plants, environmental protection, automatic control and integrated automation of nuclear power plants, technical management, etc..
- Q: How to solve the short circuit of emergency communication equipment
- Usually you see the white plate, marked with "national emergency communications," the license plate, if the following is the letter "B" at the beginning of the China Radio Association members
- Q: Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference
- Here are a few concepts, you can check1, the network voltage, is the line or the rated voltage of the bus, which is usually said to be rated voltage, including 3, 6, 10, 35, 110, 3302, rated voltage generatorThe rated voltage of the generator is usually 5% higher than the rated voltage
- 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 network equipment and the remote communication cabinet are responsible for the communication between the equipment and the background in the station and the communication with the electric power department
- Q: On the safety hazards of electric equipment safety
- 3 where in the overhead power line protection zone new, reconstruction or expansion of the building, must go to the power supply department for the approval of the relevant procedures for the safety of power facilities construction. It is forbidden to borrow, dig fish ponds, pile up or dump harmful chemicals in the power line protection zones.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.
- Q: What are the technical measures to ensure the safety of the power line equipment?
- 5 hanging sign and installing fence (fence).These are the contents of safety regulations (line part)
- 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: In order to obtain the qualification test of power equipment, the company needs to have a hard condition
- Can not be directly applied for; there will be a variety of requirements for the application, including the number of test personnel configuration (to have a certificate, no evidence of personnel does not count), test equipment configuration (to provide invoices for the purchase of equipment, there is no light
- Q: How to run a company that operates electric equipment
- Look for people who want to use the electrical equipment, such as the operator of the power station,
