Description
Technical field
The utility model relates to a kind of electricity getting device, relates in particular to a kind of coaxial slip electricity getting device.
Background technology
Coaxial slip electricity getting device can produce a large amount of heat energy in the process of work, if these heat energy are not carried out radiating treatment, and will cause damage of equipment.Existing coaxial slip electricity getting device all relies on nature cooling, so the compound brush of power taking layout is loose, to guarantee having enough spaces to realize the natural convection air heat radiation.Yet at narrow and small installing space, the size of carbon brush holder limits, and this has just caused the carbon brush quantity wretched insufficiency on the carbon brush holder, thereby the load current that causes each carbon brush to bear has substantially exceeded safe current density.Therefore, often generation is stuck because of carbon brush heating expansion, and large tracts of land is burnt the serious equipment breakdown of copper electric pole.
Simultaneously, the compound brush on existing coaxial slip electricity getting device relies on the elastic force of roll film stage clip that it is contacted with coaxial electric pole, but the elastic force of roll film stage clip is too little, easily causes contact resistance unstable, causes the equipment operating current unstable.At the carbon brush adstante febre, the elastic force of roll film stage clip is decayed rapidly, until follow the string fully, causes contact resistance to increase severely, the more severe vicious circle of generating heat, and moment causes the compound brush large tracts of land and burns.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can the high-density installation compound brush, and can realize the coaxial slip electricity getting device of fine heat radiation.
A kind of coaxial slip electricity getting device, comprise carbon brush holder, compound brush, stage clip, coaxial electric pole, characterized by further comprising cooling valve, semi-enclosed cavity and exhaust outlet, described semi-enclosed cavity forms with the coaxial electrical bar by carbon brush holder is inboard, described cooling valve one end is connected with semi-enclosed cavity, and an end of described exhaust outlet is connected with semi-enclosed cavity.
In order to solve the problems of the technologies described above, coaxial slip electricity getting device of the present utility model, the highdensity compound brush mounting means of sampling, special tangential solid matter carbon brush holder, each can install several compound brush, and can closely be connected, and only reserves the exhaust outlet of a side.The Pressure of Ambient Temperature gas of dry cleansing is cooled in the semiclosed working cavity that valve guiding introducing carbon brush holder is inboard and the coaxial electrical bar forms, aim at the direct air cooling of work contact-making surface of each compound brush and coaxial electric pole, cold gas flows around compound brush in cavity and is heated and leads exhaust outlet, the working face heat of each carbon brush is directly discharged, do not affect adjacent carbon brush.The dry cleansing cold gas has blown away the dust that is attached on coaxial electric pole simultaneously, makes contact-making surface bright and clean, has ensured better the stable of performance.
Another technical problem to be solved in the utility model is to provide a kind of coaxial slip electricity getting device that can avoid large tracts of land to burn compound brush.In order to solve this technical problem, stage clip on coaxial slip electricity getting device of the present invention adopts the magnetism-free stainless steel stage clip, the symmetrical pressure-acting of special magnetism-free stainless steel stage clip makes compound brush and coaxial electric pole close contact on compound brush, effectively reduced contact resistance.Adopt the electricity getting device of this stage clip to save maintenance cost, stablized operating current, improved the finished product rate.

Embodiment
Below in conjunction with accompanying drawing, the working of an invention mode is specifically described.
The first execution mode of the present utility model by Fig. 1 and Fig. 2 as can be known, the coaxial slip electricity getting device of this kind, comprise carbon brush holder 1, compound brush 3, stage clip 4, coaxial electric pole 5, also comprise cooling valve 2, semi-enclosed cavity 6 and exhaust outlet 7, described semi-enclosed cavity 6 forms with coaxial electric pole 5 by carbon brush holder 1 is inboard, and described cooling valve 2 one ends are connected with semi-enclosed cavity 6, and an end of described exhaust outlet 7 is connected with semi-enclosed cavity 6.Pressure of Ambient Temperature gas is cooled in valve 2 semi-enclosed cavity 6 that guiding introducing carbon brush holder 1 is inboard and coaxial electric pole 5 forms, aim at the direct air cooling of work contact-making surface of each compound brush 3 and coaxial electric pole 5, cold gas flows around compound brush 3 in cavity 6 and is heated and leads exhaust outlet 7, and the working face heat of each carbon brush is directly discharged.The coaxial slip electricity getting device of this structure can realize making the compound brush working temperature, to drop to lower than 60 ° of C more than C from 200 °.The overall dimension of this electricity getting device is consistent with existing " coaxial slip electricity getting device ", can directly replace, but carbon brush installation quantity has increased by 2/3, and the work contact-making surface of each carbon brush has increased by 1/4, and the load current that each carbon brush bears has reduced by 1 times.
The second execution mode of the present utility model is the further improvement of carrying out on the basis of the first embodiment, and the stage clip 4 in the first embodiment is replaced with the magnetism-free stainless steel stage clip.This kind magnetism-free stainless steel stage clip gives the pressure of each compound brush 3 〉=8 kilograms, has improved more than 10 times than the pressure of stage clip in former design.Better make compound brush 3 and coaxial electric pole 5 close contacts, effectively reduced contact resistance.Avoid large tracts of land to burn the accident of copper electric pole, saved cost of equipment maintenance, stablized operating current, improved the finished product rate.
