Background technique
Generator's motor shaft ground connection is most important to the reliability service of generator, and generator's motor shaft ground connection primarily serves elimination hair
The electrostatic potential of big axis over the ground when motor operation, ground connection mostly by copper pigtail ground connection or carbon brush ground connection, be grounded copper pigtail mainly by
Braiding copper pigtail is contacted with big axis, keeps contacting with big axis by self weight, but is made when generator operation since revolving speed is high and oily pollution
It must be grounded copper pigtail and big axis poor contact, influence earthing effect, lead to generator rotor ground protection exception.Carbon brush ground connection due to
The difference of device leads to the brush holder and carbon brush different sizes of installation, and conventional brush holder is to be fixedly mounted, and brush rocker structure is more multiple
It is miscellaneous, it needs to shut down replacement carbon brush after carbon brush abrasion, so seriously affects the normal operation of generator.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of ground connection brush holders for generator's motor shaft ground connection, originally
Ground connection brush holder overcomes the defect of the big axis ground connection of conventional electric generators, and structure is simple, easy for installation, it is ensured that carbon brush is reliable with big axis
It contacts, carbon brush replacement can be realized without shutting down after carbon brush abrasion, ensure that the normal operation of generator.
In order to solve the above technical problems, ground connection brush holder of the utility model for generator's motor shaft ground connection includes brush box and sets
It further include plugging pedestal, insulation plug bar, fixed block, gripping block and mounting rod in the holddown spring of the brush box side wall, it is described
Insulation plug bar is movably arranged in the plug pedestal by buckle, and the fixed block is set to the plug pedestal side, described
Gripping block is set to the fixed block side by bolt, and the adjacent surface of the fixed block and gripping block is equipped with through-hole, the installation
Bar one end is set in the through-hole and is clamped by fixed block and gripping block, and the brush box is set to the plug bar by connecting rod
And it is located at the other side of the plug pedestal.
Further, this ground connection brush holder further includes insulated handle, and the insulated handle is set to the plug bar top.
Further, this ground connection brush holder further includes transition block, and the transition block is inserted in the plug bar and passes through transition block
The screw of surrounding fastens, and when the plug bar is inserted into the plug pedestal, the transition block is located at the plug base top surface, institute
It states connecting rod two end and is separately connected the transition block and brush box.
Ground connection brush holder due to the utility model for generator's motor shaft ground connection uses above-mentioned technical proposal, i.e. this ground connection
Brush holder includes brush box and the holddown spring set on brush box side wall, further includes plug pedestal, insulation plug bar, fixed block, gripping block
And mounting rod, insulation plug bar are movably arranged in plug pedestal by buckle, fixed block is set to plug pedestal side, and gripping block is logical
Bolt is crossed set on fixed block side, the adjacent surface of fixed block and gripping block is equipped with through-hole, mounting rod one end be set in through-hole and
It is clamped by fixed block and gripping block, brush box is set to plug bar by connecting rod and is located at the other side of plug pedestal.This ground connection
Brush holder overcomes the defect of the big axis ground connection of conventional electric generators, and structure is simple, easy for installation, it is ensured that carbon brush is abutted against with big axis
It touches, carbon brush replacement can be realized without shutting down after carbon brush abrasion, ensure that the normal operation of generator.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is the ground connection brush holder structural schematic diagram that the utility model is used for generator's motor shaft ground connection.
Specific embodiment
Embodiment is as shown in Figure 1, ground connection brush holder of the utility model for generator's motor shaft ground connection includes brush box 1 and be set to
The holddown spring 2 of 1 side wall of brush box further includes plug pedestal 3, insulation plug bar 4, fixed block 5, gripping block 6 and mounting rod
7, the insulation plug bar 4 is movably arranged in the plug pedestal 3 by buckle, and the fixed block 5 is set to the plug pedestal 3
Side, the gripping block 6 are set to 5 side of fixed block by bolt 61, and the fixed block 5 and the adjacent surface of gripping block 6 are set
There is through-hole, described 7 one end of mounting rod is set in the through-hole and clamps by fixed block 5 and gripping block 6, and the brush box 1 is logical
Connecting rod 11 is crossed to be set to the plug bar 4 and be located at the other side of the plug pedestal 3.
Preferably, this ground connection brush holder further includes insulated handle 8, and the insulated handle 8 is set to 4 top of plug bar.It is logical
It crosses insulated handle and can be convenient and extract plug bar out of plug pedestal, since plug bar is integrally formed by connecting rod with brush box,
Plug bar takes brush box out of after extracting together, can carry out carbon brush replacement operation.
Preferably, this ground connection brush holder further includes transition block 9, and the transition block 9 is inserted in the plug bar 4 and passes through transition
The screw 91 of 9 surrounding of block fastens, and when the plug bar 4 is inserted into the plug pedestal 3, the transition block 9 is located at the plug bottom
3 top surfaces of seat, 11 both ends of connecting rod are separately connected the transition block 91 and brush box 1.
