Four, technical characteristics
four.1 The excitation, rectification, excitation handle, de-excitation security and other gadgets of the synchronous motor are mounted on the rotor. The rectified energy is provided by the coaxial alternator, therefore getting rid of the slip ring and carbon brush unit, creating the general structure compact and eliminating slippage. The spark made by the contact among the ring and the carbon brush.
4.two The use of new insulating supplies, semiconductor supplies and insulation technological innovation, with tremendous-strong insulation endure voltage and anti-corona capabilities.
4.three The temperature rise margin is massive. Beneath different working conditions these kinds of as begin, overload, overexcitation, underexcitation, shutdown, and so forth., it can make certain that the temperature increase of every single element does not exceed eighty% of the corresponding team temperature. The motor adopts Course F insulation, and the temperature is evaluated in accordance to the temperature rise limit of Class B insulation.
four.4 The tE time price is lengthy and the starting up time is limited. To ensure the security and trustworthiness of the motor, the tE time value of the motor is developed to be previously mentioned 9s, which is practical for users to change and use.
four.5 The security gadget is advanced and comprehensive.
4.5.one Stator windings and bearings are geared up with temperature detection products, which can monitor, alarm and excursion.
4.five.two Shutdown space heater with anti-condensation effect (improved basic safety airtight type).
4.five.three There is a purge gadget interface on the motor, and a purge pipe is created inside of the motor to discharge the internal hazardous gas before the motor starts off.
four.6 The brushless excitation program adopts a coaxial built-in composition of rotating rectifier, rotating armature AC major exciter and synchronous motor. It has automatic de-excitation protection, computerized excitation at the greatest time of polarity, and phase out of step with load. The clever computerized control perform of the out-of-action protection has a large diploma of steadiness and quick response efficiency. In addition, when the voltage of the energy source system fluctuates instantaneously and there is an oscillation, or when the pushed mechanical equipment or process has robust transient disturbance, the motor With automatic clever security and manage purpose, the affect on the procedure of the motor is a lot more compact than that of the traditional brushed synchronous motor.
five.1 The all round composition of this series of motors is a box composition, and the foundation, stop protect, bottom plate, and so forth. are welded by steel plates. The motor is an unbiased cavity, and the AC exciter and the rotating rectifier disc form an additional independent cavity.
five.2 The magnetic materials of the motor and the exciter are produced of cold-rolled silicon metal sheets with substantial magnetic permeability and minimal loss. The damping strip and the magnetic pole core adopt a specific correcting method to prevent starting up sparks all inside conductor connections, fasteners, supports and The screws on the rotating human body have free measures to make certain firmness and reliability, and keep away from sparks and arcs.
5.three The stator winding adopts dependable anti-corona measures to enhance the corona initiation voltage. The primary motor and the AC exciter winding are dealt with with VPI as a complete dipping paint, which has higher electrical overall performance, mechanical strength, insulation performance, moisture resistance and thermal stability.
5.four Undertake seat kind spherical sliding bearing. The bearings are insulated to avert shaft currents new lubricating oil and slim-walled bearing alloy tiles are utilized, and electromagnetic centerline symptoms are set.
five.five Rotating rectifier plate: The place is little on the outside of the exciter, the electrical connectors, repairing areas and warmth sink are built-in, compact composition, dependable procedure, reduced failure rate, and handy installation and routine maintenance.
6. Situations of Use
