Specifications

MRD series resistor is applicable to AC/DC circuit of 10V ~ 300KV, used for driving/braking/regulating motor, load, protection of neutral point and so on.

MRD series resistor are of safe product features, large thermal capacity, corrosion-resistance, high-temperature resistance, long lifetime and non-maintainance, etc., and of superiority when matched with high power motor. In power system it is widely used for neutral ground protection of high-voltage transformer, auto-tracking arc-supression coil damping of high voltage power distribution, harmonic filter and so forth.

Character

1. Maximum capacity, better limite voltage effect, more widely applicable scope, stronger tolerance , long lifespan

2. Voltage impact coefficient is 1, under the various kinds of electric voltage waveform, the voltage values are equal

3. With zinc oxide nonlinear resistors and discharge gap between the structure, make the two are complementary protected. The spark gap make the State-of-Charge of zinc oxide resistance to zero, Zinc oxide resistance nonlinear characteristics also make the spark gap action without free-wheeling in future, The spark gap no longer bear arcing tasks, and improve the service life of the product;

4. Four lines connect method, can be greatly reduce the voltage of phase, the reliability of the protection is greatly improved;

5. Valve plates and the spark gap assemble space, and mutual influence, discharge electrode is not easy to damp, be oxidated, make action value more stable and reliable.

6.Take overvoltage action techniques and fault automatically function , realize the device maintenance free, at the same time, to avoid the tedious work periodically, to solve the engineering and technical personnel to worry about the problems of the equipment safe running .

Q: What is the GIS in power system: Three Gorges Left Bank GIS a total of 39 switches. Left a total of 8 units of power station and the Three Gorges to Wanzhou 1 line, the Three Gorges to Longquan 1 lines, 2 lines, Three Gorges to Longquan Three Gorges to Longquan 3 lines of four circuits? Left two power plant a total of 6 units and the Three Gorges to Jingzhou 1 lines, 2 lines, Three Gorges to Jingzhou Three Gorges to Jingzhou 3 line etc. three lines.Three Gorges left bank power plant using international bidding procurement, GIS by the internationally renowned manufacturer ABB in 1999, the successful supply installation. The utility model relates to a metal sealed off phase structure, the generator transformer adopts a unit connection, and the two unit wiring is combined into a switch unit which is connected with a joint unit to connect the 3 / 2 wiring. Bus segment, 3 / 2 wiring of the 7 strings, a series of double switch off. GIS net size of about 581.5 meters long, width of 15 meters.

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: Communication signal power belongs to mechanical and electrical installation engineering. However, it is different from the mechanical and electrical installation of industrial equipment, especially the railway communication and signal system. The main differences are the following points: 1, mechanical and electrical installation is mainly refers to the installation of equipment, power, monomer debugging, linkage commissioning commissioning. Railway communication, signal, power, but there is a very strong system requirements, including the total network management system debugging, and other railway system of professional linkage debugging. For example, the signal CTCS system, track circuit and the coordination of the work system commissioning; and passenger cars, motor vehicles, truck station shunting system linkage debugging, etc.

Q: What are the necessary equipment for power line project?: It must have a climbing tool, such as irons, safety belts, safety helmet; and lifting equipment, such as cranes, hydraulic lift truck, pulley, winch, pole and so on; there must be bearing equipment, such as various tensioners, hand gourd, line cards, traction machine, tension machine;

Q: Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference: 3, rated voltage transformerRegulations, to accept the power of the primary winding, the output power of the two windings, the general, the primary winding voltage = network voltage, the voltage of the two winding due to the consideration of the loss, higher than the network voltage of 5% to 10%

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: In order to ensure the normal operation of the power system and equipment to achieve a grounding: 4) repeat grounding: in the low voltage three-phase four wire system (380V/220V), which is directly grounded in the neutral point, in addition to the working connection at the power supply, it is necessary to re connect the ground at the other place of the zero line. To ensure the safety and reliability of the zero line. It is simply to say that one or more points on the zero line are grounded again.

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: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator: The equipment you have listed has this function. The generator and the camera belong to the rotation compensation equipment

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: Power equipment is required to replace the dimension, the state has no relevant provisions: But more time has entrusted operation maintenance experience unit maintenance, power equipment to customers is good, one can improve the safe and stable operation of equipment, to meet the demand of a power supply section, on the other hand it can guarantee and increase operation life of equipment.
