Function
Most neutral of 110KV/220KV power networks are not grounded. In such systems, the neutral is easy to get overvoltage if struck by lightning or short-circuited by single-phase grounding fault. Besides most transformers are uniform insulated. This will greatly threaten insulation of neutral point. Therefore, we use MRD-NP Transformer Discharging Gap to protect neutral of transformer so as to prevent accidents from happening.
Operation Conditions
1. Applicable for indoor and outdoor.
2. Ambient temperature:-50~+55 celsius
3. Altitude: 1500m, if exceeds, we could produce as per specific details.
4. Max earthquake intensity: 8
5. Frequency:50Hz and 60Hz system
6. Max wind pressure:700Pa
Product Overview
110KV and 220KV is the main voltage grades in power supply grid, due to high voltage the neutral point usually grounds solidly or neutral point of some transformers does not ground based on requirements of relay setting and avoiding communication interference for limiting single-phase short-circuit current. By this way, the neutral point would be overvoltage caused by lightning stroke or single-phase grounding faults. Moreover most transformers are graded insulation, so the the overvoltage hazards to neutral insulation is huge. We must set a protective device preventing such accidents from occuring. MRD-NP transformer neutral gap protector of our company is such a device for it. It is produced strictly as per DL/T620-1997 overvoltage protection and insulation co-ordination of AC electrical equipments, applicable to 110 kv and 220kv power system where transformer neutral point does not ground.

- 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: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.
- This is not the regulations of state Power Grid Corp to their line of work area to do some local line area for engineering team to do is sign the contract established general warranty of 1 years seems to include tower structure, grounding resistance, line fitting, a line on what channel estimation problem in within the scope of the contract
- 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 equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment
- Power equipment classification:1 the sequence of electric power in power system can be divided intoPower generating equipment, power generation equipment, power transmission equipment and electric equipment2 the main role of the power system can be divided intoPrimary equipment, two equipment
- Q:All I know is a generator, a transformer. I also want to fully understand the power system related to the equipment, from power generation to end users (enterprises, factories, they will design the equipment, production equipment is not to say, but they will be transferred to the electricity, in use is the processing equipment, such as transformer, I only know this involved) equipment, detailed list, thank you ah
- Primary equipment is:The power plant and substation, generator transformer (step-up / step-down transformer), busbar, circuit breaker, isolating switch, current transformer, voltage transformer, insulator, reactor, lightning protection equipment (arrester, lightning), grounding device, electric energy metering.Business side: step-down transformer, circuit breaker, isolating switch, current transformer, voltage transformer, insulator, lightning protection and grounding device, the internal power supply generator, reactive power compensation cabinet, electric energy metering,
- Q:Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed
- Install the network need to debug the SERC issued installation (repair, test) power facilities permit five level or above qualification this debugging can be tender, can be a one-time construction units and the tender requirements: business license qualification certificate (grade 3) safety production license, the SERC issued Denso (repair, test) power facilities permit five level or above qualification
- Q:Recently went out to do the test, do not know the difference between the two tests
- Preventive testing is to test or test equipment periodically and regularly. For example, once a month, 3 months or a few times a year of preventive testing or testing, to exclude the existence of hidden dangers...
- Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the equipment and equipment
- High voltage means high voltage, similar to the above. Alternating current has active power and reactive power, the frequency response is the balance of active power, and the voltage response is reactive power balance
- Q:How to run a company that operates electric equipment
- First to find a company to do the power equipment, their prices, of course, the ex factory price to come over
- Q:How to handle the qualification test, what kind of power equipment
