Description

Generator brush holder dust cover structure

Technical field

The utility model relates to a kind of dust gathering arresters of generator, and in particular to a kind of generator brush holder dust cover structure.

Background technique

Generator, especially hydrogenerator, carbon brush are arranged on brush carrier, and the front end of carbon brush is contacted with collector ring, Effect is by the collector ring on slip ring, to provide the power supply (the usually exciting current of direct current) of generator external to rotor Winding on (excitation winding), since collector ring is in high speed rotary motion, therefore the front end of carbon brush is worn always, carbon brush abrasion meeting A large amount of tiny carbon dusts are formed, carbon dust is spread in the carbon brush chamber of generator, and is rotated under the drive of air-flow, if not to this A little dust are dusted processing, will necessarily with the inside for rotating into generator of unit, further pollute stator winding with Excitation winding etc. also will cause the failures such as coil short to influence the safe operation of unit when serious.

In the prior art, as disclosed in 202210609 U of CN " generator electrification change brush and carbon powder collecting device ", including Generator Slip Ring and brush holder and carbon brush component, opposite sliding, the brush holder between Generator Slip Ring and brush holder and carbon brush component And carbon brush component front end is the carbon brush being in contact with Generator Slip Ring, carbon brush rear end is provided with constant pressure wind spring；Brush holder and Carbon brush component include two groups arrange above and below charge dismounting carbon brush brush box, can be charged between dismounting carbon brush brush box at two groups, if It is equipped with dead ring；Enclosed hood surrounds brush holder and carbon brush component, forms closed cavity；One end of dust collection pipeline and closed cavity It is connected, the other end is connected with dust suction processing unit；The dust suction processing unit includes shell, on the shell be equipped with into Air port and air outlet, air inlet and air outlet are connected to through the gas passage in shell；Electrostatic filter bag is equipped on gas passage And blower；Brush holder and carbon brush component are surrounded with enclosed hood, closed cavity is formed, dust suction processing unit is recycled to aspirate closing chamber Intracorporal carbonaceous gas, and gas is handled, carbon dust is separated, pollution air is prevented.

But existing dust gathering arrester (enclosed hood) its there are following deficiencies: 1, dust gathering arrester is all an overall structure, disassembly When it is inconvenient, it is necessary to brush holder integral demounting could be taken out or be installed, keep the maintenance of collector ring inconvenient, increase workload； 2, dust gathering arrester is transparent materials, only installs observation window in local location aperture, visual angle is restricted, it is difficult to observe dust Overall condition in cover；3, dust gathering arrester is all made of mold molding, wastes plenty of time manufacture mold in process of production, and make Make very difficult, higher cost.

Summary of the invention

In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide one kind just In installation and removal, convenient for the generator brush holder dust cover structure of the overall condition in observation dust gathering arrester.

In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:

A kind of generator brush holder dust cover structure, including engine block are provided with collector ring, brush on engine block Hold, the front end of brush carrier is arranged in carbon brush, upper conducting ring and lower conducting ring, carbon brush, contact to form galvanic circle with collector ring, top Brush carrier contacted with upper conducting ring, the brush carrier of lower part is contacted with lower conducting ring；It is characterized in that, setting is led under in upper conducting ring Dust gathering arrester between electric ring is split type structure, is made of two pieces and components above, and the contact site of carbon brush and collector ring is sealed It closes or semiclosed；It offers hole on dust gathering arrester to pass through for carbon brush, dust gathering arrester is transparence material.

Further feature is that dust gathering arrester forms circular configuration by two pieces and components above.

It is corresponding with the contact site of carbon brush and collector ring on lower conducting ring, dust-containing disc is set.

Dust-containing disc is L-shape.

Dust-containing disc is by screw or is bolted on lower conducting ring.

In the connecting portion of dust gathering arrester and upper conducting ring, lower conducting ring, transition link block is respectively set.

Transition link block is L-shape, and a side of dust gathering arrester and L-shaped transition link block passes through screw or bolt respectively Connection, another side of transition link block passes through screw or bolt again and connect with upper conducting ring or lower conducting ring.

The brush holder that brush carrier is arranged is vertically arranged dual slot structure, and each slot can cooperate one brush carrier of insertion.

Compared with prior art, the generator brush holder dust cover structure of the utility model has the advantages that

1, the dust gathering arrester of the utility model forms a full circle by several pieces of organic glasses, keeps dust gathering arrester easy to disassemble and pacifies Dress；In the maintenance of collector ring, without brush holder integral demounting can be dismantled dust gathering arrester, workload is greatly reduced.

2, dust gathering arrester uses transparent material, such as organic glass, tempered glass, can collection in comprehensive observation dust gathering arrester The working condition of electric ring and carbon brush contact surface.

3, dust gathering arrester is made of several pieces of transparent materials, reduces difficulty of processing, shortens the production cycle, reduces production cost.

4, brush holder uses vertical dual slot structure, and can fix two can charge disassembly brush carrier, make limited around collector ring Space in the more brush carriers of arrangement.With the fast development of science and technology, generator capacity constantly increases, and leads to required carbon brush quantity Increase, since collector ring surrounding space is limited, it is desirable to increase more carbon brush as a great problem, using the double of the utility model The brush holder of inserting slot construction can be such that the carbon brush quantity of circumference doubles.
