Deskripsi Produk
Generally used in chemical industry INCREASED-SAFETY BRUSHLESS EXCITATION SYNCHRONOUS MOTOR
TAW series increased safety brushless excitation synchronous motor is a high-tech product developed by our company that integrates explosion-proof technology, power electronic technology, automatic control technology, and motor technology. It is widely used in places with explosive and dangerous gas in petroleum, chemical, coal and other industries to drive reciprocating compressors. This series of motors adopts new technology, new materials, new technology, exquisite material selection, and sophisticated manufacturing. It has the characteristics of small size, light weight, beautiful appearance, high efficiency, low noise, low vibration, safe and reliable operation, and convenient use and maintenance.Our company is the first domestic enterprise with R&D, design and production capabilities of such products. This series of motors have won the National Major Technical Equipment Achievement Award, the Provincial Major Science and Technology Project Award, and the explosion-proof electrical industrial product production license issued by the State Administration of Quality Supervision, Inspection and Quarantine.2. Implementation standardsGB 3836.1-2010 Electrical Equipment for Explosive Gas Atmosphere Part 1: General RequirementsGB3836.3-2010 Electrical Equipment for Explosive Gas Atmosphere Part 3: Increased Safety "e"GB3836.9-2006 "Explosive environment explosion-proof electrical equipment, encapsulated electrical equipment"GB755-2008 Rotating Motor Rating and PerformanceJB/T 8973-2011 Explosion-proof technical requirements for increased-safety brushless excitation synchronous motorsJB/T 8974-2011 TAW series increased safety brushless excitation synchronous motor technical conditionsGB 50058 Code for Design of Electric Power Equipment in Explosion and Fire Hazardous Environment3. Basic technical parametersPower range: 350~10000kWVoltage: 3000, 6000, 10000VSpeed: 300, 333, 375r/min (other speeds can also be manufactured as required)Rated frequency: 50HzProtection level: IP54Insulation class: FQuota: S1 (work system)Cooling method: IC81W, IC91WInstallation method: IM7315, IM7311, IM7111, IM7115Explosion-proof mark: Exe II CT2Gc, ExeII CT3GcFour, technical characteristics4.1 The excitation, rectification, excitation control, de-excitation protection and other devices of the synchronous motor are installed on the rotor. The rectified power is supplied by the coaxial alternator, thus eliminating the slip ring and carbon brush device, making the overall structure compact and eliminating slippage. The spark produced by the contact between the ring and the carbon brush.4.2 The use of new insulating materials, semiconductor materials and insulation technology, with super-strong insulation withstand voltage and anti-corona capabilities.4.3 The temperature rise margin is large. Under various working conditions such as start, overload, overexcitation, underexcitation, shutdown, etc., it can ensure that the temperature rise of each part does not exceed 80% of the corresponding group temperature. The motor adopts Class F insulation, and the temperature is evaluated according to the temperature rise limit of Class B insulation.4.4 The tE time value is long and the starting time is short. To ensure the safety and reliability of the motor, the tE time value of the motor is designed to be above 9s, which is convenient for users to adjust and use.4.5 The protection device is advanced and complete.4.5.1 Stator windings and bearings are equipped with temperature detection devices, which can monitor, alarm and trip.4.5.2 Shutdown space heater with anti-condensation effect (increased safety airtight type).4.5.3 There is a purge device interface on the motor, and a purge pipe is designed inside the motor to discharge the internal dangerous gas before the motor starts.4.6 The brushless excitation system adopts a coaxial integrated structure of rotating rectifier, rotating armature AC main exciter and synchronous motor. It has automatic de-excitation protection, automatic excitation at the best time of polarity, and step out of step with load. The intelligent automatic control function of the out-of-step protection has a high degree of stability and fast response performance. Moreover, when the voltage of the power supply system fluctuates instantaneously and there is an oscillation, or when the driven mechanical equipment or process has strong transient disturbance, the motor With automatic intelligent protection and control function, the impact on the operation of the motor is much smaller than that of the traditional brushed synchronous motor.
structural form5.1 The overall structure of this series of motors is a box structure, and the base, end cover, bottom plate, etc. are welded by steel plates. The motor is an independent cavity, and the AC exciter and the rotating rectifier disc form another independent cavity.5.2 The magnetic materials of the motor and the exciter are made of cold-rolled silicon steel sheets with high magnetic permeability and low loss. The damping strip and the magnetic pole core adopt a special fixing method to prevent starting sparks; all internal conductor connections, fasteners, supports and The screws on the rotating body have loose measures to ensure firmness and reliability, and avoid sparks and arcs.5.3 The stator winding adopts reliable anti-corona measures to increase the corona initiation voltage. The main motor and the AC exciter winding are treated with VPI as a whole dipping paint, which has high electrical performance, mechanical strength, insulation performance, moisture resistance and thermal stability.5.4 Adopt seat type spherical sliding bearing. The bearings are insulated to prevent shaft currents; new lubricating oil and thin-walled bearing alloy tiles are used, and electromagnetic centerline signs are set.5.5 Rotating rectifier plate: The position is small on the outside of the exciter, the electrical connectors, fixing parts and heat sink are integrated, compact structure, reliable operation, low failure rate, and convenient installation and maintenance.6. Conditions of Use6.1 Voltage fluctuation: ±5%, (It can run at ±10% under the condition of 7.3 in GB755)6.2 Frequency fluctuation: ±2%6.3 The altitude does not exceed 1000m.6.4 The maximum ambient air temperature does not exceed +40ºC, and the minimum is 0ºC.6.5 Zone 2 explosion hazard place formed by combustible gas or steam and air with ignition temperature group T1-T3 group.For example,
