Four, complex qualities
four.1 The excitation, rectification, excitation control, de-excitation defense and other products of the synchronous motor are put in on the rotor. The rectified energy is provided by the coaxial alternator, as a result reducing the slip ring and carbon brush unit, producing the general construction compact and eliminating slippage. The spark made by the speak to between the ring and the carbon brush.
four.2 The use of new insulating components, semiconductor materials and insulation technologies, with tremendous-robust insulation withstand voltage and anti-corona capabilities.
4.three The temperature increase margin is huge. Below numerous operating situations such as commence, overload, overexcitation, underexcitation, shutdown, and many others., it can guarantee that the temperature rise of every part does not exceed eighty% of the corresponding team temperature. The motor adopts Class F insulation, and the temperature is evaluated in accordance to the temperature increase restrict of Class B insulation.
four.four The tE time benefit is extended and the commencing time is brief. To make sure the protection and dependability of the motor, the tE time price of the motor is developed to be over 9s, which is convenient for customers to modify and use.
4.5 The security system is sophisticated and comprehensive.
four.5.1 Stator windings and bearings are outfitted with temperature detection products, which can check, alarm and vacation.
four.5.two Shutdown area heater with anti-condensation impact (enhanced security airtight variety).
four.5.three There is a purge gadget interface on the motor, and a purge pipe is created within the motor to discharge the inside dangerous gasoline before the motor begins.
four.six The brushless excitation program adopts a coaxial built-in structure of rotating rectifier, rotating armature AC main exciter and synchronous motor. It has computerized de-excitation safety, automatic excitation at the greatest time of polarity, and step out of phase with load. The smart automatic management purpose of the out-of-step safety has a large degree of security and quick reaction performance. In addition, when the voltage of the electrical power offer program fluctuates instantaneously and there is an oscillation, or when the pushed mechanical tools or procedure has robust transient disturbance, the motor With automatic clever security and control purpose, the influence on the operation of the motor is significantly scaled-down than that of the classic brushed synchronous motor.

structural form
5.1 The total construction of this series of motors is a box framework, and the foundation, finish go over, bottom plate, etc. are welded by metal plates. The motor is an unbiased cavity, and the AC exciter and the rotating rectifier disc sort another unbiased cavity.
5.2 The magnetic supplies of the motor and the exciter are created of chilly-rolled silicon steel sheets with large magnetic permeability and low reduction. The damping strip and the magnetic pole core undertake a special correcting strategy to avoid commencing sparks all interior conductor connections, fasteners, supports and The screws on the rotating entire body have unfastened actions to make certain firmness and dependability, and stay away from sparks and arcs.
five.3 The stator winding adopts reliable anti-corona actions to improve the corona initiation voltage. The major motor and the AC exciter winding are taken care of with VPI as a total dipping paint, which has high electrical overall performance, mechanical power, insulation overall performance, moisture resistance and thermal steadiness.
5.four Adopt seat sort spherical sliding bearing. The bearings are insulated to prevent shaft currents new lubricating oil and thin-walled bearing alloy tiles are employed, and electromagnetic centerline indications are set.
5.five Rotating rectifier plate: The position is small on the exterior of the exciter, the electrical connectors, repairing parts and warmth sink are built-in, compact framework, reliable procedure, low failure charge, and convenient set up and servicing.
6. Circumstances of Use Voltage fluctuation: ±5%, (It can run at ±10% beneath the problem of seven.3 in GB755)
6.two Frequency fluctuation: ±2%
six.3 The altitude does not exceed 1000m.
six.four The highest ambient air temperature does not exceed +40ºC, and the least is 0ºC.
6.5 Zone 2 explosion hazard location shaped by flamable fuel or steam and air with ignition temperature team T1-T3 group.
