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:Pre checking and checking of goods in power system
Pilot: the full name of the preventive test, generally in terms of a power system equipment, in order to find in the operation of equipment problems, to prevent the occurrence of accidents or damage to equipment, equipment for inspection, testing or monitoring, including oil sampling test or gas samples. The preventive test is the operation of power equipment and to maintain an important aspect of the work
Q:Power test equipment sales to find power supply company which departments?
Procurement is generally the Department of materials management, to find a high class, livelihood, materials department
Q:Is the GIS in the electric power high voltage switch cabinet
GIS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.
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:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
For 35/6KV step-down stationEach line with the 6/0.4KV transformer, or 6KV equipment (such as 6KV synchronous motor), are the load of the stationSo, there are 6KV devices, single occupancy 6KV bus on a certain line can be
Q:What is the installation equipment of the transformer on the power installation project
Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.
Q:How to handle the qualification test, what kind of power equipment
(a) legal person qualification and perfect organization; (two) the registered capital and net assets of 60 million yuan; (three) the last 3 years to bear the following first items listed, third project and second sub items listed in any one project, and the project quality: above 1 thousand and 330 volts voltage substation 2 or 220 thousand volt substation 5; more than 2 thousand and 330 volt overhead lines 300 kilometers or 220 thousand volt overhead line of 500 kilometers; more than 3 thousand and 220 volt cable line 80 kilometers or 100 meters above the level crossing tower crossing project 1.
Q:What is the double name of power equipment?
The double name of equipment refers to the name and number of the equipment.The name of the equipment is Chinese, the number is Arabia. Together is a double name. The same station, will not appear the same name, or the same number, is the only. The only combination of the two can be more accurate.
Q:Electric power automation equipment
Power grid dispatching automation, power system analysis and control, power electronics, power market, distribution automation,
Q:What equipment is necessary on the list of electrical engineering equipment?
MSXB-F-75kVA/720kV frequency conversion resonance withstand voltage test device, MSDBF-30kVA multi frequency induction withstand voltage test device,
