Product Description:

 

 

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 is the meaning of the power equipment in criminal law
Not yet installed agricultural low-voltage lighting circuit, not in the use of electrical equipment. Even if the person who took part in the erection of the wire, it will not cause harm to public safety, its behavior should be qualitative theft.
Q:What are the relevant national standards for power equipment?
The standard is very thin do not know what you want to give you some of the specific power of the main reference
Q:What is the good rate of equipment determined by the rating of substation equipment
With China's state-owned enterprises economic autonomy to the enterprise, the equipment management should also be extended: the demand rate of sound equipment, ensure the normal operation of equipment is the most important management goal, extended to the assessment of fixed assets created by the economic benefits
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: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..
Q:What is the concentrator of the power set
There are two types of remote meter reading devices in electric power generation: one is low voltage set, called concentrator, the other is called terminal. The concentrator role is the number of meter data, first by the carrier or 485 communication way to collect the equipment, and then through the cable (optical fiber) or wireless network (cdma/gprs) transmitted to the main station.
Q:Buildings, factories, institutions, power distribution room of the power equipment as required
Construction of electricity, then it is necessary to look at the site to enter the electricity equipment, under normal circumstances, with 380, 220V power is enough
Q:Reactive power compensation methods commonly used in power equipment
For the operation of specific projects, the compensation can be divided into: in situ dispersion compensation and centralized compensation.In situ compensation is to set up a reactive power compensation device on the spot to compensate for a single device. However, the need for compensation equipment, large investment, maintenance management is not easy.
Q:Pre checking and checking of goods in power system
That is one of the effective means to ensure the safe operation of electrical equipment. Over the years, the power sector and power equipment of large industrial and mining enterprises are basically in accordance with the rules of the preventive test of power equipment issued by former Ministry of electric power "(hereinafter referred to as the" Regulations ") requirements for testing, the timely detection and diagnosis equipment defects play an important role.
Q:The role of electrical equipment handover and preventive testing
The purpose of the test is to test the performance of the equipment to prevent the occurrence of the fault, the former is the first time after the installation of the equipment to change the nature of the acceptance test, which is run during the routine. The content of the test items are different.You check the 1 power standards will know, since you do this test should have a standard hand.
