Description
Technical field
The utility model belongs to the technical field that generator is made, and relates to a kind of novel turbo generator set carbon brush configuration.
Background technology
Carbon brush is widely used in the turbo generator silicon-controlled static exciting system as a kind of sliding contact part.In turbo generator set, it is being undertaken the task of DC excitation electric current is provided in the generator amature excitation winding.Carbon brush is installed on the support as the sliding contact body of motor conduction current, forms the fixing carbon brush configuration of a cover, has promptly formed an important conduction hinge of whole excitation system.In a single day carbon brush configuration breaks down, and just can impact even the off-the-line shutdown to turbo generator set, and therefore, the reliability of carbon brush configuration is to the important role in safe operation of silicon-controlled static excitation turbo generator set.
Traditional current collecting equipment adopts copper casting as carbon brush support and conductive component, member is comparatively heavy, brush is to be installed in singly in the preformed hole of cast copper support circle distribution, installation is than comparatively dense, loaded down with trivial details, and be unfavorable for the cooling of ventilating, bad if any casting quality problem or the installation of some brush, its operational reliability will reduce greatly.At present, domestic turbo generator set adopts copper casting with the carbon brush configuration conducting bracket more, and brush then is to be installed in respectively in each preformed hole of cast copper support circumferencial direction by single brush carrier.There is the shortcoming of the following aspects in the carbon brush configuration of this pattern: the one, and the foundry goods volume is big, and is comparatively heavy, and difficulty of processing is big, and brush is installed also more loaded down with trivial details; The 2nd, brush is installed than comparatively dense, axially, the radial ventilation cooling effect is not good; The 3rd, in case some brush installation quality is bad or the conducting bracket casting quality is poor, brushgear will face the excessive and condition of burning of local current, and this also is that power plant least is ready the result that sees.
Summary of the invention
The purpose of this utility model is in order to overcome problem and the defective that above-mentioned prior art exists, and provide a kind of novel turbo generator set succinct, quick and easy for installation, that reliability is high carbon brush configuration, this device after compound brush carrier is integrated, be installed on the support more a plurality of carbon brush, circumference comprises several compound brush carriers, form a cover ventilation good cooling results at last, the carbon brush configuration that security reliability is high.
The purpose of this utility model can realize by following technical proposals:
Novel turbo generator set carbon brush configuration, form by positive and negative two utmost points, wind scooper, air-ducting ring, fixed support, underframe, compound brush carrier, conducting copper, insulation board, insulating base, negative or positive electrode is made up of connecting copper bar, current collection ring flat-plate, holder, it is characterized in that: positive and negative two utmost points are fixed between fixed support, the underframe by insulation board, insulating base respectively, insulation board, insulating base all play insulating effect, and fixed support and underframe work connecting copper bar, current collection ring flat-plate, the holder effect of reinforcing; And positive and negative two utmost points are distributed in the wind scooper both sides symmetrically, and air-ducting ring is installed in the wind scooper both sides, and wind-guiding encloses guide functions, allow cool off the distinguished and admirable in wind scooper of current collection ring flat-plate and carbon brush; Fix a conducting copper on the holder of negative or positive electrode, the conducting copper other end links by contact hole and power plant's excitation cable, 2-6 single carbon brush is assembled together and forms compound brush carrier, the current collection ring flat-plate of described negative or positive electrode is made up of four semicircle copper ring plates, per two semicircle copper ring plates are connected forms a full circle between connecting copper bar and the holder, four semicircle copper ring plates are connected forms two full circle between connecting copper bar and the holder, several compound brush carriers become circle distribution to be assemblied in the centre of two full circle current collection ring flat-plates.Wind scooper cooperates centrifugal fan on the rotor of steam turbo generator will cool off hot blast behind current collection ring flat-plate and the carbon brush and carbon dust to guide special-purpose air duct below the underframe into; Underframe rises and supports and cold and hot wind shunting action.
The utility model is for the effect that helps centrifugal fan on the rotor of steam turbo generator and wind scooper, the cooling air that forces flow through carbon brush and turbo generator current collection ring flat-plate surface flows to special-purpose cooling air channel under the underframe through wind scooper, so both cooled off carbon brush and collector ring, the dust collection with carbon brush and collector ring friction generation had been arrived in the air channel.
Large-scale integral cast copper support is made into two current collection ring flat-plates to the utility model and small-sized cast copper holder is formed, and significantly reduced the foundry work amount, and the minimizing of whole carbon brush assembling volume weight, for enterprise has saved cost.Reasonably the ventilation type of cooling has promptly been cooled off current collection ring flat-plate and carbon brush, has effectively collected carbon dust again.More than 2 energy-conserving and environment-protective policies of all having catered to China.First integrated carbon brush, after in groups the mode of assembling help the cooling of ventilating, and can effectively suppress local pyrexia, promote the operational reliability of carbon brush configuration greatly.
