4, complex traits
four.1 The excitation, rectification, excitation management, de-excitation security and other units of the synchronous motor are set up on the rotor. The rectified electrical power is provided by the coaxial alternator, hence removing the slip ring and carbon brush system, generating the all round composition compact and eliminating slippage. The spark developed by the make contact with amongst the ring and the carbon brush.
4.two The use of new insulating components, semiconductor materials and insulation technologies, with super-strong insulation face up to voltage and anti-corona abilities.
four.three The temperature increase margin is large. Underneath a variety of working situations this sort of as commence, overload, overexcitation, underexcitation, shutdown, and so forth., it can make certain that the temperature increase of every element does not exceed eighty% of the corresponding group temperature. The motor adopts Course F insulation, and the temperature is evaluated according to the temperature increase restrict of Course B insulation.
4.4 The tE time benefit is lengthy and the commencing time is short. To ensure the security and trustworthiness of the motor, the tE time worth of the motor is developed to be above 9s, which is hassle-free for customers to alter and use.
four.5 The security unit is innovative and comprehensive.
four.five.1 Stator windings and bearings are outfitted with temperature detection products, which can keep an eye on, alarm and journey.
4.five.2 Shutdown place heater with anti-condensation effect (increased basic safety airtight type).
four.five.three There is a purge system interface on the motor, and a purge pipe is made within the motor to discharge the inner dangerous gasoline ahead of the motor begins.
four.six The brushless excitation technique adopts a coaxial built-in framework 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 phase out of phase with load. The smart computerized handle operate of the out-of-stage security has a high degree of steadiness and quickly reaction efficiency. Moreover, when the voltage of the power offer program fluctuates instantaneously and there is an oscillation, or when the pushed mechanical equipment or approach has robust transient disturbance, the motor With automated clever safety and management purpose, the influence on the procedure of the motor is considerably smaller than that of the traditional brushed synchronous motor.
structural form
5.one The all round construction of this sequence of motors is a box construction, and the base, end include, base plate, etc. are welded by steel plates. The motor is an unbiased cavity, and the AC exciter and the rotating rectifier disc kind another unbiased cavity.
5.2 The magnetic resources of the motor and the exciter are created of chilly-rolled silicon steel sheets with higher magnetic permeability and reduced decline. The damping strip and the magnetic pole main adopt a special correcting approach to prevent commencing sparks all interior conductor connections, fasteners, supports and The screws on the rotating human body have unfastened measures to make certain firmness and trustworthiness, and steer clear of sparks and arcs.
five.3 The stator winding adopts dependable anti-corona measures to enhance the corona initiation voltage. The major motor and the AC exciter winding are dealt with with VPI as a entire dipping paint, which has large electrical overall performance, mechanical energy, insulation functionality, humidity resistance and thermal stability.
five.4 Undertake seat variety spherical sliding bearing. The bearings are insulated to stop shaft currents new lubricating oil and thin-walled bearing alloy tiles are employed, and electromagnetic centerline symptoms are established.
5.five Rotating rectifier plate: The position is little on the outdoors of the exciter, the electrical connectors, fixing areas and heat sink are built-in, compact construction, reputable procedure, lower failure charge, and hassle-free installation and servicing.
6. Situations of Use
six.one Voltage fluctuation: ±5%, (It can run at ±10% underneath the issue of 7.three in GB755)
