1. Summarize 1.1. DYQ4 series liquid resistor starter (for short starter as follow) is a new starter prepared for improving the starting property of high voltage squirrel-cage alternating current asynchronously motor. It can induce the impact which is brought to motor starting current on power system, and improve the start smoothness with equipment by voltage-reduced starting by way of liquid resistance. It can protect the motor avoid harm by over-load, phase failure, short circuit etc.It is the prefect starting production instead of auto-induction voltage-reduced starter. 1.2. Model explanation 2. Working principles: The device is composed of resistor, high-voltage soft start controller, isolating cabinet, changeover cabinet and star point controller. We supply in full sets. The device can start motor and play a protected action on motor start process, when connect it in motor start circuit. This resistor is composed of three phase balancing resistor which have negative temperature characteristic, when the current is past through resistor, the temperature of resistor gradually increase and its resistance gradually decrease, then the terminal voltage of motor gradually raise and the start torque gradually increase, so the motor can start smoothly and the start current can be decreased. 3. Application scope: DYQ4 series high-voltage resistance soft starter is suitable for large and medium high-voltage squirrel-cage asynchronous motor or asynchronously-started synchronous motor, to voltage-reduced starting. The motor which start by this device have soft start characters like withlow and constant starting current, torque increased gradually etc. In start process, without current and mechanical shock, as well as have little impact on power system, and without electromagnetic interference. It is the prefect production instead of starting reactor auto-induction voltage-reduced starter. And compare with high-voltage inverter soft starter, DYQ4 have many evident advantages: simple operation, withoutmaintenance and no pollution of harmonic wave etc. 4. Advantage: 4.1. constant current, soft start: the starting current is 2.5-3.5 times as motor rated running current, avoid generating more heat while motor starting, can reduce the demand of transformer capacity with motor heavy load start, reduce no-recurring investment 4.2. The wave of the power system voltage and load cant influence the start process, it can start successfully at one time. 4.3. smooth starting, without shock to machinery, can prolong the service life about 30% of machinery and motor. 4.4. have large thermal capacity, and the continual starting attempt can reach 3-5 times 4.5. have little impact on power system, have small voltage drop during starting 4.6. have high power factor during starting 4.7. without harmonic wave pollution 4.8.start with static changeable resistor,safety and reliability 4.9. simple operation, maintenance free DYQ4 with standard design, have the advantage of low and constant starting current , have small voltage drop and big power factor during starting, without pollution of harmonic wave and simple, simple, safety and reliability etc. 5.

Three-phase transformers are used to convert the available 3-phase mains voltage into any load voltage. To cater for the wide range of application areas involved,these transformers are essentially available in the same kinds of designs as the single-phase transformers, e.g. Three-phase dry-type transformer: separate winding version Three-phase series transformer: autotransformer winding version Three-phase safety, isolating, mains or insulating transformer: separate winding version In terms of how the 3 coils are connected, there are various options available and each of these provides the transformers with specific properties. The vector group code is composed of the following elements: The upper-case letter indicates the higher-voltage winding (the highest voltage in terms of operation). The lower-case letter indicates the lower-voltage winding. The brought-out neutral is indicated by means of N or n (depending on voltage level). â?¢ The distinctive number indicates the phase angle of the lower voltage in relation to the higher voltage (distinctive number multiplied by 30). The following winding connection options are available Delta: D, d Wye (or star): Y, y Zigzag: Z, z Example: Dyn5 Higher-voltage winding is delta-connected. Lower-voltage winding is star-connected with a brought-out neutral. The lower voltage lags behind the higher voltage by 150�° (5 x 30�°). Unless specifically requested otherwise, the transformers are configured with a double-star connection and a brought-out neutral (vector group Yyn0); for autotransformers the vector group is YNa0. Our three-phase transformer range includes all our standardised types for the 25 30.0 kVA performance range and a frequency of 50/60 Hz

The advantages of them are outstanding. In general, they are low ignition temperature, high activity in low temperature, high-resistant crushed strength etc. If can be used together with medium temperature type catalyst, such as, S101, you can make more profits; for instance, high conversion, and lowering environmental pollution. Type S108 is low temperature catalysts which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission. 3.LS112 Type Cesium Catalyst(VK59/69/Cs120/110) Low ignition temperature; higher activity in low temperature; high-resistant crushed strength, high anti- poison; high anti- pulverization etc. LS112 cesium-promoted catalyst integrates not only the active constituent of vanadium pentoxide and the promoters of cesium and potassium salts, but also the carrier of select diatomaceous earth. Its activity under low and high temperature conditions keeps high due to the unique manufacturing process and optimized formulation. Cesium-promoted catalyst enables new opportunities for improvement in start-up time, energy efficiency of electricity throughout the operating cycle and strong reduction in SO2 emission that far lower than national standard. The product is the all-around catalyst suited for all stages in converter due to its low ignition temperature and good heat tolerance under high temperature condition. Cs series enables the compliance with pollutant emission standards due to its enhanced activity and longer service life.

Take the sulfur and burn it with oxygen to make SO2. Then, direct the stream of SO2 gas into a reactor bed with some vanadium pentoxide catalyst and extra oxygen gas to make sulfur trioxide gas which is the acid anhydride of sulfuric acid. vanadium pentoxide is added to in the contact phase of making of sulfuric acid. V2O5 acts as a catalyst at 450�¢?? where SO2 is made to react with the left over O2 in the first step. Vanadium pentoxide series of sulfuric acid catalysts can be used in the process of sulfuric acid production, to be more specific, is the process of SO2+I/2O2---SO3. With the help of Vanadium Catalyst, the rate of conversion can be improved greatly. It can guarantee the air speed of operation to add 10-20% more when using type star ring catalysts or ring catalysts. Vanadium catalyst can be applied in many fields, such as, sulfur-based acid production, pyrite-based acid production, nonferrous smelting gas-based acid production, gypsum-based acid production etc. Type S101 Catalyst is a medium broad temperature vanadium catalyst which promotes the oxidation from SO2 to SO3, and it is developed by China. With 20 years of manufacturing S101 catalyst, it has reached the international advanced level. Due to its high-quality and steady performance, The advantages of S101 are as listed. Wide applicability, broad range of temperature, high conversion, and high mechanical strength etc. Ring or plum blossom shaped catalysts have solved some problems that cylinder-shaped catalyst encountered; namely, they are small pellets, high pressure drop and high energy consumption, bad resistance of dust accumulation. Type S101 series are broad temperature catalysts which suit for every bed of converter. Type S108 Series sulfuric acid catalysts are invented in early 80 s by China. The advantages of them are outstanding. In general, they are low ignition temperature, high activity in low temperature, high-resistant crushed strength etc. If can be used together with medium temperature type catalyst, such as, S101, you can make more profits; for instance, high conversion, and lowering environmental pollution. Type S108 is low temperature catalysts which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission.
