| Our complete device of arc & harmonic control and voltage protection is based on innovative theory, with full function and high automation. It could quickly eliminates electric arc, arc flash transient overvoltage, ferromagnetic resonace associated with ground fault by increasing current instantly to locat the ground line accurately, widely used in 3-35kv power grid in eletricity, metallurgy, chemical enterprises, coal mining, petroleum and industries like such. Main Functions 1.To replace PT cabinet and supply testing signal of voltage 2.With function of voltage protection, the device could limit atmosphere overvoltage and operating overvoltage at a lower level, so as to ensure insulation safty of power grid and electric equipment and reduce accidents casued by overvoltage a lot. 3. To replace arc-suppression coil, eliminate intermittent arc-grounding fault quickly, suppress intermittent arc-grounding overvoltage, prevent accidents from deteriorating and reduce accidental trip probability of wire. 4. To limit and eliminate various resonant overvoltage quickly and effectively, prevent aging-acceleration of system insulation structure caused by long time resonant overvoltage, avoid resonant overvoltage effection to power grid setting like arrester as well as small inductive load, increase safty & stability of system operation, and lengthen lifetime of system equipment. 5. To look up single-phase faulty wire accurately and quickly, prevent accident from deteriorating, reduce workload of operation and maintainance people. 6. The device possesses the function of switching TV. |
- Q: What are the characteristics of the grounding of the power system and equipment?
- The grounding - is the need for work and set up the ground, such as: high current transformer neutral point grounding, primary voltage transformer neutral grounding, 380/220V three-phase four wire neutral grounding, etc..
- 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: Under the same voltage level, the rated voltage of the equipment is not exactly the same
- For different electric appliances, rated voltage may be different, commonly used for 220V, 280V, and some appliances used in not rated voltage can still work, but not up to the ideal working condition, rated voltage and the voltage at both ends of the electric appliance has nothing to do with.
- Q: The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!
- The complete set of power distribution equipment is a complete set of equipment supplied by the manufacturer. The electric main circuit is divided into a plurality of units, each unit is a circuit, and the circuit breaker, the knife gate, the current transformer and the voltage transformer of each unit are connected
- Q: What are the effects of frequency variation on power users and power systems?
- Influence of frequency variation on power users and power systems:There is a close relationship between the frequency of power equipment and the operation of power system
- Q: What specific enterprises and units are used to test the power of the equipment ah
- Electrical installation company, has installed for repair, test qualification. The test is power detection.
- Q: Electric power equipment start-up and commissioning of the project there is a difference?
- After a single commissioning, and then linkage test, after the test, such as no-load, put into operation in the above steps are completed, the test is no problem, start running with load.
- 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.
- According to the "construction quality management regulations," the fortieth: the scope of the warranty and its normal use of the corresponding minimum warranty period of 2 years.
- Q: What principles should be followed in power equipment maintenance
- (3) the maintenance of equipment should be combined with the technical renovation, and the equipment renewal plan should be made according to the defects of the equipment and the need of the development of the power network.The basic principles of emergency repair of electric power equipment should follow the principle of "selecting weight and avoiding light" and "using the signal first.".
- Q: Power equipment is required to replace the dimension, the state has no relevant provisions
- This depends on the provisions of the local power supply department, generally not mandatory requirements.
