For adopting exciting transformer also to there is rectification function as field power supply. Excitation unit can provide separately, also can be used as generating equipment and provides together.
Excitation unit can be divided into rotary excitation and the large class of state type excitation two by rectifier system. Wherein rotary excitation comprises that again direct current exchanges and brushless excitation; State type excitation comprises potential source static excitation machine and composite power source static excitation machine. Excitation sorting technique is a lot, such as the AC power supply mode according to generator excitation is classified: the first kind is by powering with the AC exciter of generator coaxle, be called AC excitation (separate excitation) system, this system can be divided into again four kinds of modes: 1, AC exciter (magnetic field rotating) adds static silicon rectifier (having brush), 2, AC exciter (magnetic field rotating) adds static silicon controlled rectifier rectifying device (having brush), 3, AC exciter (armature rotation) adds silicon rectifier (brushless), and 4, AC exciter (armature rotation) adds silicon controlled rectifier (SCR) (brushless). Equations of The Second Kind is to adopt transformer-supplied, be called full static excitation (self-excitation) system, when exciting transformer is connected on the machine end of generator or is connected on the station service bus of modular generating set, be called self-excitation excitation mode, the exciter converter that machine end exciting transformer is connected with generator unit stator combined to the calling from compound excitation excitation mode of generator amature power supply, and this associated methods also has four kinds: 1, DC side parallel, 2, DC side series connection, 3, AC parallel connection, 4, AC series connection.
Present percussion drill uses the full manual feed of leaning on, and wastes time and energy, and security is not high, and the noise producing is very large, can have influence on people around's work and life when construction.
