| 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:When a fault occurs in power system, the circuit breaker tripping device near fault
- When a fault occurs in power system, the circuit breaker tripping device near the fault, in order to reduce the power outage, this is the relay protection ().A, selective B, reliability C, sensitivity D, non selectivity
- Q:What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!
- The necessity of power equipment testingPower equipment is the hub and channel in the transmission and distribution network, in the course of the use of equipment will be aging, disrepair, hidden trouble, etc.. However, these situations can not be ruled out by the eyes of the people, the staff of the experience, it is necessary to detect the special power equipment to check out these security risks and the organization of human resources in a timely manner to exclude.In the operation of electric power, the safety of electric power has always been a chord of the electric power. Power equipment testing is actually played a role in prevention and detection of hidden dangers. So it is very important to detect the electric equipment (i.e., the preventive test of electric equipment).
- Q:The problem of electric power equipment withstand voltageWhy does the pressure decrease when the altitude is high? The air is thin, is not easy to breakdown (vacuum breakdown is not very low atmospheric pressure)
- Because of the low air pressure in the air at high altitude, at the same voltage
- 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:Is the GIS in the electric power high voltage switch cabinet
- High voltage electrical (mainly above 35kV) exposed to the air, common substation circuit breaker, isolating switch, bus, phases, equipment, and equipment between between and so must have a relatively large safety distance. This area is relatively large, but also exposed to the outside of the security risks are more. GIS is a kind of technology, the bus CircuitBreakers isolating switch for high-voltage electric appliances shell pack, seal filled with six sulfur hexafluoride gas, according to the elements of seal, not a whole big box, such as every bus from the outside is a large cylinder etc.. This equipment can be very compact layout, and a sealed shell, but also more secure.High voltage switchgear is only a device installed in a cabinet, and this is generally high voltage 10kV, up to 35kV, and then there is no general high switch cabinet this form. Of course, you can also use GIS technology. But generally speaking, GIS is more than 110kV GIS switch station.You can Baidu image search GIS switch station". You can see that the big cylinder together is the GIS switch equipment, large cylinder which is the bus, circuit breakers and other equipment, see pictures more intuitive.
- Q:Definition of power equipment defects
- Personal opinion: defects and hidden dangers have certain differences, can not be equated with the...
- Q:Withstand voltage test, power equipment insulation unqualified reasons?
- Voltage test, power equipment insulation failure may be due to: insulation deterioration. Such as transformer oil into the water, solid insulation moisture, insulation aging, etc., will lead to decreased insulation performance, in the pressure test may not be qualified.
- Q:What are the technical measures to ensure the safety of the power line equipment?
- Electricity, electricity, hang the ground and install signage, hanging Obscuration using personal security line
- Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- A device with a motor can be called a rotating device. Power system mainly refers to the generator, motor
- Q:Private enterprises must be free transfer of power facilities
- 1, belonging to the public nature of the public utility lines or occupy the planning corridor, by the unified management of power supply enterprises. The power supply enterprise shall reach an agreement on the operation, maintenance and management of power supply facilities prior to the handover. The power supply enterprise shall retain the capacity of the original owner in the above-mentioned agreement for the public power supply facilities for unified operation and maintenance management.2, belonging to the nature of the user, but not in the public substation power supply facilities, by the user operation and maintenance management. If the user operation and maintenance management is indeed difficult, with the power supply enterprises to negotiate, commissioned on behalf of the power supply enterprise operation and maintenance management matters related to the signing of the agreement.3, belong to the user sharing nature of the power supply facilities, by the owner of the property rights of common operation and maintenance management. If the user has difficulty in running and maintaining management, it can negotiate with the power supply enterprise to sign the agreement on behalf of the power supply enterprise on behalf of the operation and maintenance management.
