Description
Technical Field
The utility model belongs to the technical field of electric specialty, a dismantle safety device of exciter sliding ring is related to.
Background
The carbon brush of the exciter is a device for transferring electric energy between the moving and the static of a rotating machine in the generator, ensures that direct-current voltage rectified by the rectifier is transmitted to a rotating slip ring on a rotor through the carbon brush, continuously generates magnetic poles for the rotor of the generator, and enables a stator coil and a magnetic field of the generator to cut magnetic lines. The main components are an exciter slip ring protective cover, a carbon brush spring, a carbon brush and the like, the exciter slip ring protective cover is fixed on the exciter, the exciter slip ring protective cover is made of iron and is heavy in weight, and the carbon brush spring is pressed on the carbon brush to ensure that the carbon brush has certain pressure. The carbon brush is mainly made of graphite and can be continuously abraded due to continuous friction in the generator. Usually, 1/2 is needed to be replaced in time when being ground, otherwise, the pressure of the carbon brush is insufficient, sparks are generated, and the collector slip ring is damaged, so the replacement frequency of the carbon brush is high, the carbon brush needs to be replaced in the running process, a heavy exciter slip ring protective cover needs to be detached during replacement, the short circuit of an exciter rotor loop is easily caused in the detachment process, and the safety is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a dismantle safety device of exciter sliding ring to solve current exciter sliding ring protection casing and dismantle the low problem of security.
In order to solve the above problem, the utility model discloses a technical scheme is: the protection cover is fixed on the exciter through bolts, the protection cover further comprises a guide rod, a sliding hole is formed in the protection cover, a screw hole is formed in the exciter, one end of the guide rod is provided with threads and penetrates through the sliding hole to be screwed in the screw hole, a nut is sleeved on the guide rod and screwed on the threads, the protection cover is fixed on the exciter, a clamping groove is formed in the other end of the guide rod, and the guide rod is clamped on the clamping groove through a wrench, is convenient to disassemble and assemble.
In the above technical solution, a more specific technical solution may also be: the clamping grooves are formed in the two sides of the guide rod.
Further: the two sliding holes are distributed on two sides of the protective cover, the two screw holes are corresponding to the two sliding holes, and the two guide rods are respectively arranged in the two sliding holes and the two screw holes in a penetrating mode and then screwed into the nuts.
Further: the lengths of the two guide rods are equal to the depth of the protective cover.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has: the protection casing can steadily be dismantled from the exciter through the guide arm, guarantees that the protection casing can not touch rotor circuit and cause the short circuit, and fail safe nature is high, has simple structure, and the protection casing can be dismantled alone to the characteristics of simple operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a left side view of fig. 1.
In the figure: 1. an exciter; 2. a protective cover; 3. a bolt; 4. a guide bar; 41. a card slot; 5. and (4) a nut.
Detailed Description
The invention will be described in more detail with reference to the following examples:
the safety protection device for detaching the exciter slip ring as shown in fig. 1 and fig. 2 comprises an exciter 1 and a protective cover 2, wherein the protective cover 2 is fixed on the exciter 1 through a bolt 3, the safety protection device further comprises a guide rod 4, the protective cover 2 is provided with a sliding hole, the exciter 1 is provided with a screw hole, one end of the guide rod 4 is provided with a thread which penetrates through the sliding hole and is screwed in the screw hole, the guide rod 4 is sleeved with a nut 5 and is screwed on the thread, and the other end of the guide rod 4 is provided with a clamping groove 41; clamping grooves 41 are formed in the two sides of the guide rod 4; the two sliding holes are distributed on two sides of the protective cover 2, the two screw holes are corresponding to the two sliding holes, and the two guide rods 4 are respectively arranged in the two sliding holes and the two screw holes in a penetrating manner and then are screwed in the nuts; the length of the two guide rods 4 is equal to the depth of the protective cover 2.
During installation, a wrench is used for screwing the two guide rods 4 into screw holes at two sides of the exciter 1 through the clamping grooves 41, the sliding holes at two sides of the protective cover 2 are arranged on the two guide rods 4, the protective cover 2 slides to the exciter 1 along the two guide rods 4 and then nuts are screwed, and then the bolts 3 are screwed to fix the protective cover 2 on the exciter 1; during the dismantlement, the bolt 3 on the protection casing 2 is lifted off to the unscrewing, and the nut on two guide arms 4 is lifted off to the unscrewing again, and the protection casing 2 is being supported by two guide arms 4 and can not drop, consequently does not need extra personnel to support the protection casing 2, only need alone lift the protection casing 2 off along guide arm 4 can, guarantee that the protection casing 2 can not touch rotor circuit and cause the short circuit, uses the spanner centre gripping to lift two guide arms 4 off at draw-in groove 41 at last.
