Which items need to be verified before operating a diesel generator set
Today, the technicians of Beidou Power Generator Company will summarize for everyone the three aspects that the operators must confirm before the operation of the newly taken over diesel generator set. The specific details are as follows: Verify which self-protection functions the diesel generat...Read more -
The external characteristics of synchronous generators
The external characteristics of a synchronous generator generally refer to the curve of the voltage variation at the generator terminal when the load current changes while the internal electromotive force remains constant. The main test is the longitudinal axis synchronous reactance of the genera...Read more -
Fault Diagnosis and Elimination of Synchronous generators
1. The generator is overheating (1) The generator did not operate in accordance with the prescribed technical conditions, such as the stator voltage being too high and the iron loss increasing; When the load current is too large, the copper loss of the stator winding increases. The frequen...Read more -
The structure and principle of synchronous generators
1. Structure The synchronous generator is mainly composed of the stator, rotor and other components. The stator part includes the stator core, stator winding, and frame; the rotor part includes the rotor core, excitation winding and slip rings (for the hidden-pole rotor, there are also sleeve and...Read more -
Inspection and handling of faults in lead-acid batteries
First, stop the regular maintenance charging of the battery, and then discharge it at a rate for 2 hours. During the discharge process, measure the voltage of the battery from time to time and select the “backward” batteries with insufficient discharge capacity for disposal. First, ad...Read more -
The concept of lead-acid batteries
1. Fundamental definition Electrical energy can be obtained through various forms of energy quality changes. Among them, the installation that converts chemical energy into electrical energy is called a chemical battery, which is generally simply referred to as a battery. Batteries can be ...Read more -
Remote network management system for diesel generator sets
The remote control functions include: remote control on/off, fault reset, emergency shutdown, and ATS primary and backup switching units. The telemetry functions include: three-phase output voltage, three-phase output current, output frequency/speed, temperature of the cooling medium or cylinder...Read more -
Why does oil sometimes drip from the exhaust pipe when the generator load is too low
Why does oil sometimes drip from the exhaust pipe when the generator load is too low? If the unit operates under a small load, as the running time continues, the following faults will occur 1. The piston-cylinder liner seal is not good, causing engine oil to seep up and enter the combusti...Read more -
The principle of an alternator
The alternator utilizes the principle of electromagnetic induction to convert the mechanical energy driven by the engine to rotate the generator shaft into electrical energy for output. According to Faraday’s law of electromagnetic induction, when the magnetic flux (the number of magnetic ...Read more -
The development trend and research direction of linear motors
Development trend At present, the development of direct drive technology for linear motors shows the following trends: Linear servo motors used in machine tool feed systems will be dominated by permanent magnet types. Integrate the motor, encoder, guide rail, cable, etc., reduce th...Read more -
The development and application of linear motors
The development of linear motors abroad Development history The starting point of the development of linear motors is not much later than that of rotary motors. Shortly after the appearance of rotary motors in the world, the prototype of linear motors emerged. However, the development pro...Read more -
Analysis of the Advantages and Disadvantages of Linear Motors
(1) There is no mechanical contact. The transmission force is generated in the air gap, and there is no other friction except for the guide rail. (2) It features a simple structure, small size, and achieves linear drive with a small number of components, with only one moving part. (3) Th...Read more
