Abstract
The utility model belongs to electric power accessories and especially relates to a double-taper-angle locking combined brush holder, which comprises a brush box (1), a handle (5), a brush holder installation guard board (4), a brush holder base (3) provided with a horizontal taper dovetail groove (3-1) and a double-taper-angle plug (2) provided with a horizontal taper dovetail boss (2-1). Horizontal taper and dovetail of the horizontal taper dovetail groove (3-1) fit with those of the horizontal taper dovetail boss (2-1). The horizontal taper dovetail boss (2-1) of the double-taper-angle plug (2) is inserted in the horizontal taper dovetail groove (3-1) of the brush holder base. According to the double-taper-angle locking combined brush holder, insufficiencies of an old-fashioned brush holder are made up, conductive contact surface is increased, operating stability of the brush holder is raised, auxiliary accessories of the base are reduced, and operation safety of the brush holder is raised. As mechanical fit between the brush box and the brush holder base is stable, the brush holder operates more stably on the set, current output of an excitation system is more stable and balanced, and service life of the brush holder is prolonged.
Description
Technical field
The utility model belongs to the electric power accessory, particularly a kind of double tapered angle locking type combination brush carrier.
Background technology
The combination brush carrier is mounted in a critical component on the generator excitation system, and stablizing of its theory of mechanics and technical performance reaches the fastening of assembly, directly influences the operation of generating set.Old-fashioned combination brush carrier assembly is more; parts such as coping screw come off at work and cause the phenomenon of conflux system's scaling loss, compressor emergency shutdown to happen occasionally; the soundness that makes up in the brush carrier area size, the combination of the connection of conduction accessory and contact-making surface in addition all is electric current to be passed through and excitation system steady operation basic; old-fashioned combination brush carrier is unstable and bonded area is little because of contact-making surface, and system's hot operation is bad to happen occasionally and cause.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, can increase conductive contact surfaces, improves the double tapered angle locking type combination brush carrier of safety and stability.
The technical scheme that the utility model technical solution problem adopts is: double tapered angle locking type combination brush carrier comprises brush box, handle, brush carrier installation backplate, be characterized in that the brush carrier base is provided with a horizontal tapering dovetail groove, the double tapered angle plug is provided with a horizontal tapering dovetail boss, horizontal tapering and the dovetail of the horizontal tapering of horizontal tapering dovetail groove and dovetail and horizontal tapering dovetail boss match, and the horizontal tapering dovetail boss of double tapered angle plug is inserted in the horizontal tapering dovetail groove of brush carrier base.
The beneficial effects of the utility model are: double tapered angle locking type combination brush carrier remedies and has changed the deficiency of old-fashioned brush carrier, increase conductive contact surfaces, improved the stability of brush carrier work, reduced the auxiliary accessories of base, improved the fail safe of brush carrier work, brush box cooperates stable with brush carrier base machinery, makes brush carrier get up more steady in the unit operation, the excitation system electric current is exported stable equilibrium more, the useful life of also having improved brush carrier simultaneously.
