Abstract
This invention relates to an automatic-dust-collection carbon brush device; insulating dust collection boxes are respectively arranged on the lateral face of each carbon brush along the rotating direction of a hydraulic turbine generator; the insulating dust collection boxes are connected with a dust collection distributor respectively through an insulating tube, wherein two ends of the insulating tube are provided with quickly-screwed tube joints; the dust collection distributor is connected with a dust collection master pipe; and the other end of the dust collection master pipe is connected with a dust collector. According to the device disclosed by this invention, the dust collector absorbs powder dust generated by the carbon brush in a working procedure through a dust collection box besides each carbon brush so as to realize the purpose of dust collection; each carbon brush has the dust collection boxes; and the device disclosed by this invention is characterized by good powder dust absorption effect, compact structure and convenient mounting and is beneficial to radiating a hydraulic turbine generator set.
Description
Technical field: the present invention relates to a kind of from the dust suction carbon brush configuration.
Background technology: the exciting current of hydraulic generator will be delivered in the magnetic pole winding of generator through several carbon brush.Collector ring with the generator rotation during carbon brush work contacts delivered current; Friction and heating constantly take place simultaneously; The interior electrographite brush of the carbon brush generation dust that weares and teares at work, these dust possibly pollute generating set, and possibly cause the charged position of the unit accident that is short-circuited.Therefore must carbon dust be collected with dust catcher.Conventional way is: make a big dust gathering arrester with insulating material, the whole collector ring outside and all carbon brush are all covered, and offer some dust collections hole at the dust gathering arrester periphery, be connected on the dust catcher through pipeline.This way causes the dust assimilation effect difference of each carbon brush owing to the air quantity maldistribution, owing to draw badly, is unfavorable for the heat radiation of collector ring, and carbon brush inspection, replacing bother, the installation of dust gathering arrester, fixed structure complicacy.
Summary of the invention: the purpose of this invention is to provide a kind of simple in structure, dust collection is effective, easy to maintenance from the dust suction carbon brush configuration.Technical scheme of the present invention is: a kind of from the dust suction carbon brush configuration; The insulation dust-absorbing box is all installed along the direction of rotation of hydraulic generator in the side of each carbon brush; The flexible insulated hose that the insulation dust-absorbing box is equipped with the hose coupling of screwing fast through two ends is connected respectively with to the dust suction distributor; The dust suction distributor connects the dust suction house steward, and the dust suction house steward other end connects dust catcher.The present invention all installs an insulation dust-absorbing box in the side of each carbon brush along the direction of rotation of hydraulic generator, and the flexible insulated hose that the insulation dust-absorbing box is equipped with the hose coupling of screwing fast through two ends is connected respectively on the dust suction distributor.Dust catcher is directly connected on the dust suction distributor through the dust suction house steward.The negative pressure that produces when dust catcher is worked so evenly is delivered to through pipeline in the dust-absorbing box on each carbon brush next door, and the dust that produces during with each carbon brush work directly siphons away.Speed up owing to dust-absorbing box surrounding air flows simultaneously, also help the heat radiation of collector ring and carbon brush.The flexible pipe of each linkage section also makes things convenient for each element of this device to install except that playing insulating effect.
The invention has the beneficial effects as follows: adopt the carbon brush configuration of such scheme, its carbon brush dust-absorbing box adopts the insulating material manufacturing, is riveted on the side of carbon brush, and dust-absorbing box is a semi-closed state, front opening, and threaded sweep-up pipe is established in the back.All dust-absorbing box all are connected on the dust suction distributor through screw the fast flexible insulated hose of joint of two ends band.Dust catcher adopts a dust suction house steward to be connected with the dust suction distributor, and the dust that each dust-absorbing box is collected siphons away.Its advantage is: 1, cancelled traditional huge dust gathering arrester, simplified the structure.2, each carbon brush next door all has dust-absorbing box to collect dust, and dust collection is effective.3, dust-absorbing box adopts the joint of screwing fast to be connected the current check of carbon brush, dust-absorbing box, easy to maintenance with flexible insulated hose.When 4, dust catcher is worked, around each carbon brush, all produce certain negative pressure, carbon brush surrounding air is flowed speed up, help heat radiation.5, dust-absorbing box, flexible pipe are insulating material, can not cause accidents such as short circuit, discharge, and be safe in utilization.

Embodiment
As shown in Figure 1 from the dust suction carbon brush configuration; An insulation dust-absorbing box 1 is all installed along the direction of rotation of hydraulic generator in the side of each carbon brush; Like Fig. 3, shown in Figure 4, the flexible insulated hose 2 that insulation dust-absorbing box 1 is equipped with the hose coupling of screwing fast through two ends is connected with dust suction distributor 3 respectively.As shown in Figure 1, the carbon brush 6 that is used to import same polarity electric current is installed in same conducting ring 7.
As shown in Figure 2, dust catcher 5 is directly connected to the end face of dust suction distributor 3 through dust suction house steward 4, and the dust that produces during with each carbon brush work directly siphons away.Around each carbon brush certain negative pressure is arranged all, carbon brush surrounding air is flowed speed up, help heat radiation.The flexible pipe of each linkage section also makes things convenient for each element of this device to install except that playing insulating effect.Dust-absorbing box, flexible pipe are insulating material, can not cause accidents such as short circuit, discharge, and be safe in utilization.Because dust-absorbing box adopts the joint of screwing fast to be connected the current check of carbon brush, dust-absorbing box, easy to maintenance with flexible insulated hose.
