Transformer netral titik kesenjangan perlindungan perangkat , Transformer neutral titik jurang peranti perlindungan, 110kv transformer neutral protection gap device,220kv transformer neutral overvoltage protection gap, neutral point overvoltage protedtion device
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:Reactive power compensation methods commonly used in power equipment
- The centralized compensation is to set up the reactive power compensation device in the power distribution room to compensate the reactive power in the region. Due to the introduction of several kinds of compensation sampling is set at the point of measurement, so you can minimize the interest rate generated electricity.In the professional field and transmission line compensation (high and low), furnace low-pressure grid compensation, flameproof compensation device etc..
- Q:Is there a warranty period for power equipment?
- Therefore, every year there must be high and low voltage as well as the relevant leakage test, consistent with the standard that is to continue to use.
- Q:The cost calculation of power equipment
- Fault and professional people to do the cost of fault handling and so on, there is no fixed standard, depending on the site
- Q:Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?
- The service life of different engineering equipment specification is different
- Q:Power equipment sales process, the customer asked the most questions thank you
- The questions asked by customers vary from person to person:1, the brand or model in which the same industry used, that is, customer performance, the region has no performance;2, product quality, how to use life, and other domestic brands compared to what level, quality assurance, such as a few years;
- Q:Would like to ask: railway communication, signal, power equipment installation related to mechanical and electrical engineering? If belong to, including specific aspects. Thank you
- 3, in fact, including the power of the two professional: power and electrification. Including contact network infrastructure, post, wire rack, remote control, lightning protection system, station lighting intelligent control etc..Belong to the scope of the installation should be the station (communication station) equipment into the test, the basis of processing and installation, equipment installation, commissioning of the single body, the electrical subsystem Unicom debugging, the whole system of professional debugging unicom. And other railway professional with the commissioning test, etc..
- Q:1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?
- The network equipment and the remote communication cabinet are responsible for the communication between the equipment and the background in the station and the communication with the electric power department
- Q:The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!
- Three refers to the anti moisture, salt spray, anti mildew.According to the complete set of electrical as well as five: (1) to prevent the wrong points, close circuit breaker;2) to prevent the pull and load isolation switch;3) to prevent the electrification (hanging) grounding switch (line);4) to prevent the ground wire (switch) with circuit breaker (isolation switch);5) to prevent straying into the charged interval.
- Q:What specific enterprises and units are used to test the power of the equipment ah
- Electric Power Bureau must be used to detect classes, each project must be checked by the Electricity Industry Bureau
- Q:The production and transportation process of electric power
- The equipment of the two system comprises a measuring device, a control device, a relay protection device, an automatic control device, a DC system and necessary auxiliary equipment. Power system voltage level has 220V, 380V (0.4 kV), 3 kV, 6 kV, 10 kV, 20 kV, 35 kV, 66 kV, 110 kV, 220 kV, 330 kV, 500 kV, 750kV, 1000kV. With the improvement of motor manufacturing process, 10 kV motor has been mass production, so the use of kV, 6 kV has been less than 20 kV, 66 kV is also rarely used. The power supply system is 10 kV and 35 kV. Transmission and distribution system to 110 kV or above. Power plant generator has 6 kV, 10 kV and, with a total of 20 kV, users are 220V, 380V (0.4 kV) low voltage system 20kV.
