Abstract
The utility model provides a multi-speed fan system for a transformer, which comprises a motor, fan blades mounted on the motor, a temperature protecting contact point embedded in a coil of the motor, an intelligent controller connected with the temperature protecting contact point, and a remote control room connected with the intelligent controller, wherein the temperature protecting contact point is automatically disconnected when the temperature of the coil of the motor is too high and is automatically reset when the temperature is decreased.
Description
Technical field
The utility model belongs to the transformer technology field, and particularly a kind of transformer is with how fast blower fan system.
Background technology
Blower fan is on electric equipment heat abstractors such as transformer, to use, and is used for reducing oil tank of transformer internal heat oil temperature.
When oil-filled transformer normally moved, the oil in the fuel tank raise the fuel tank internal temperature because coil heating is heated.This temperature such as untimely release will influence transformer's life span and safety.It is exactly that the temperature in the fuel tank is reduced that heat dissipation equipment is installed, and blower fan is that transformer is with very crucial part in the heat abstractor.
Along with the development of intelligent grid, for transformer and assembly operating require increasingly highly, wherein heat abstractor is the important device of tranformer protection, therefore, development and developing intellectual resource type heat abstractor are of great significance to the development of intelligent grid.
In view of above problem, be necessary to provide in fact a kind of transformer with how fast blower fan system to solve above technical problem.
The utility model content
The utility model provides a kind of transformer with how fast blower fan system; This blower fan system is to dispose especially for unattended intelligent substation; Can be at any time in the ruuning situation of controlling indoor monitoring heat dissipating device of transformer fan far away; Through intelligent means transformer station is managed and security control, grasp the transformer running status, the generation of prevention and caution accident.
The technical scheme that the utility model adopted is: a kind of transformer is with how fast blower fan system; Comprise motor, be installed in fan blade on the motor, be embedded in the temperature sense contact in the coil of motor; The intelligent controller that is connected with the temperature sense contact, and the control room, a distant place that links to each other with intelligent controller.
Said how fast blower fan system further includes terminal box, and said temperature sense contact is drawn joint by lead and is connected on the temperature protection contact in the terminal box, and the power supply contact n that links to each other with intelligent controller further is installed on this terminal box;
Said power supply contact n comprises different contacts so that blower fan moves with different rotating speed;
Said intelligent controller further comprises the transducer of connected detection temperature of oil in transformer.
The utility model transformer has the following advantages with how fast blower fan system at least: the utility model blower fan is provided with temperature sense contact TC, and it directly is embedded between the coil of motor, draws joint to terminal box by lead; During fan operation; When (high excessively like stall, overload, power supply shakiness, phase shortage, ambient temperature) made the internal temperature of motor coil reach set point if fault, the temperature sense contact TC in the motor was automatic disconnection, exported a passive signal that cut-offs; Can in time pinpoint the problems and solve fault; After pending fault was got rid of the coil cooling, TC can automatically reset, thereby realized the Based Intelligent Control to equipment.In addition; The utility model blower fan system can be when temperature of oil in transformer be higher, and blower fan can run up, and temperature of oil in transformer is reduced very soon; When temperature of oil in transformer is low; Blower fan can middling speed/vulgar running, and temperature of oil in transformer is reduced, thus the effect that reaches energy savings and reduce noise pollution.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model transformer with how fast blower fan system.
Embodiment
Below in conjunction with accompanying drawing the utility model transformer is done detailed description with how fast blower fan system:
See also shown in Figure 1; The utility model transformer comprises motor 1 with how fast blower fan system, and fan blade 2 is installed on this motor 1, and this motor 1 bottom comprises terminal box 3; Temperature protection contact TK and power supply contact n5 are installed in this terminal box 3; Said terminal box 3 is connected with intelligent controller 6 through power supply contact 5, and this intelligent controller 6 is connected with transducer 7, and this intelligent controller 6 is connected with control room, a distant place 8 through holding wire.
Between the coil of said motor 1, be embedded with temperature sense contact TC; It is drawn on the temperature protection contact TK of joint in the terminal box by lead, during fan operation, when the internal temperature of (high excessively like stall, overload, power supply shakiness, phase shortage, ambient temperature) causes motor coil reaches design temperature if fault; Be embedded in temperature sense contact TC in the motor 1 with automatic disconnection; Export a passive signal that cut-offs, after pending fault was got rid of the coil cooling, thermotonus contact TC automatically reset.
Said power supply contact n comprises that different contacts can make blower fan move with different rotating speed, and the required rotating speed of blower fan under condition when intelligent controller 6 is judged through gathering environmental information reaches the purpose of energy-saving and noise-reducing.
Said intelligent controller further is connected with transducer; This transducer is used to detect the oil temperature of transformer; Said transducer is sent to intelligent controller with the current signal that detected temperature of oil in transformer converts 4-20mA into, and intelligent controller is according to the rotating speed of this Signal Regulation blower fan then.
The above is merely a kind of execution mode of the utility model; It or not whole or unique execution mode; The conversion of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model specification, the claim that is the utility model contains.
