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:The difference between electric load and power supply capacity
There is a correlation coefficient between them, the power supply capacity = power load * demand coefficient.
Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
The transformer is non rotating equipment. There are a lot of rotating equipment in power plants, such as fans, fans and so on, of course, the most important is the generator
Q:How to solve the short circuit of emergency communication equipment
, a number of amateur radio enthusiasts, radio license, the application of their own call sign plate, usually just play the role of decoration,
Q:What is the power plant
Production of generators and other power generation equipment, and some will produce some electricity, belonging to the state monopoly of the infrastructure industry.
Q:What are the necessary equipment for power line project?
There are connection tools, such as hydraulic pliers, crimping pliers, pressing tools, connecting tube, detonation pressure tube; the last is a measuring device, theodolite, rod, etc. in addition to the measuring rod; excavation tools such as shovels, iron, hammer and so on.
Q:What are the two devices in the power system
Your question is somewhat ambiguous, as I understand the following: the two equipment is a device for the work of the control, protection, monitoring and measurement equipment
Q:On the nameplate of the electrical equipment, what does ith UE ie mean?
Electrical equipment (Electrical Equipment) is in the power system of generators, transformers, power lines, circuit breakers and other equipment collectively.
Q:What is the power system and the power grid 2 what is the rated voltage of electrical equipment
Power system is a kind of electric power production and consumption industry chain, which is from generation to generation. When the "power system" as an industry name, it includes power generation, for (transmission) electricity, power construction, power design, power test, power scheduling, etc..
Q:Power equipment are used, can help to divide some of the details
When drawing the main wiring diagram, the transformer, arrester, capacitor, neutral point equipment and carrier communication can be used to reflect the situation of power supply in normal and accident conditions. Electrical wiring is also known as the main electrical
Q:Electrical equipment classification
Mainly there:Equipment for the production and conversion of electrical energy, such as generators, motors, transformers, etc.;Switch on or off circuit breaker, such as circuit breaker, isolating switch, contactor, fuse, etc.
