The main reasons for the reduction of the insulation of the generator rotor
The main reasons for the reduction of the insulation of the generator rotor 1.1 The rotor’s insulation resistance drops below the allowable value due to moisture absorption. This can occur if the generator is shut down for a long period, or if the environment is humid for other reasons. &n...Read more -
Performance Comprehensive Analysis of Generator Automatic Switching System
(1). Automatic Generator Switching Function: 1. Self-starting Function: · When the mains power is lost, the unit automatically starts. · Number of allowed startups: three times. · Time for each startup and closing the circuit breaker: 5 to 8 seconds. · When the startup is successful once, the tot...Read more -
How should the protection parameters of the generator set be set
How should the protection parameters of the generator set be set? The diesel engine used in the diesel generator set is prone to sudden and severe damage during use. It is necessary to install protection devices on the generator set. When the oil pipe of the generator bursts and there is a lack o...Read more -
Detailed Explanation of Generator Set Parallelization Project
I. Main Functions of the Parallel Cabinet The automatic paralleling system provides a fully electronic protection system for faults such as short circuits, overloads, overvoltages, and reverse power in the generator sets. This ensures the safe and reliable operation of the generators. When multip...Read more -
Analysis and Suggestions for Electric Brush Faults in Circuits
Enhance the understanding of the oxide film on the brush surface, and establish the conditions for its formation and normal operation: Several recent failures were mainly caused by the inability to form a lubricating layer on the oxide film of the brush surface. The formation of the oxide film r...Read more -
Common causes and solutions for faults of brushes and collector rings
Common faults of the brush during operation include overheating, generating sparks, severe damage to the brush holder and the collector ring. From the causes of overheating faults, there are mainly the following aspects: 1. Overheating due to poor ventilation: Poor ventilation mainly results fro...Read more -
How to identify and handle the situation when the oil pressure is too high
1. Phenomenon When the engine is operating, the oil pressure gauge indicates an excessively high oil pressure value that exceeds the specified limit. 2. Cause Analysis From the principle that the lubrication system generates pressure by the oil pump, it can be known that the lubricating oil in t...Read more -
The components of a standard diesel generator set
An ordinary diesel generator set mainly consists of a diesel engine, a generator, and a control system. There are two connection methods for the diesel engine and the generator: one is a flexible connection, where the two parts are connected together using a coupling; the other is a rigid connect...Read more -
A Brief Discussion on the Generator Grid Connection Breaker System
Power plants often use generators as backup power sources to cope with power outages in the grid, failures of power supply equipment, and equipment maintenance. When a power outage occurs, the generator should automatically start within a few seconds to supply power to the feeder cabinet and elec...Read more -
Measures for controlling noise
(1). Aerodynamic Noise Control: 1. Intake Noise Control: Most engines are equipped with air filters, which can significantly reduce intake noise and make it a secondary sound source. However, when other sound sources are further controlled, intake noise may become the main sound source. At this p...Read more -
Analysis of Noise Causes of Diesel Generator Sets
Diesel engine noise is a complex sound source composed of multiple sound sources. According to the radiation mode of the noise, diesel engine noise can be divided into air dynamic noise and surface radiation noise. According to the mechanism of generation, diesel engine surface radiation noise ca...Read more -
Explanation of Parallel Operation of Three-Phase Generators
The parallel operation of three-phase generators requires that in the circuit formed by connecting the generators to the grid, no inrush current should be generated. The following conditions must be met: (1) The voltages of the generators should be the same in magnitude and phase; (2) The frequen...Read more
