Description
Technical field
The utility model belongs to light-duty box technical field of generators, is a kind of ventilation cooling type generator exciter supporting structure.
Background technology
In known technology, the exciter support of generator adopts circumference soldering muscle two ends to be the form of connecting flange usually, one end of support is encouraged above end end plate at support by flange and Bolt Connection or is encouraged on end end cap, the other end of support by flange and Bolt Connection on exciter outer cover.This structure deposits defect in the following areas: one is that the welding of exciter support top muscle causes when not dismantling exciter support, exciter end bearing cannot be overhauled, if maintenance needs to open and inspect the parts such as exciter, permanent magnetic motor, dismounting difficulty is large, time-consuming; Two is the circumference muscle of exciter support and the bearing with end cover of exciter end, by the restriction of rack space position, easily interferes bottom it, needs thus to lengthen exciter support or change position welding; Three is that the circumference muscle of exciter support and bearing oil inlet and oil return pipe are easily interfered, and needs to change position welding; Four is that the uncertainty of exciter support circumference muscle welding position easily causes generator to encourage the vibration of end; Five is limit by exciter support structure, causes the dismounting difficulty of exciter large, make to encourage end bearing dismounting and change difficulty and also performance of ventilation and heat dispersion bad.
Utility model content
The purpose of this utility model is to provide one and can realizes generator and encourage end bearing replacing for convenience detach, and effectively can solve bearing and oil inlet and oil return pipe is easily interfered, the end vibration problem such as large encouraged by generator, and the ventilation cooling type generator exciter supporting structure that result of ventilating heat dissipation is good.
Realizing the technical scheme that the purpose of this utility model takes is: this exciter support structure comprises exciter base for supporting, exciter guide duct and exciter outer cover, wherein, exciter base for supporting is arranged on generator by base end plate and encourages on the installed surface of end end cap lower outer setting, on the top of exciter base for supporting, exciter outer cover is housed, bottom is provided with exciter guide duct, one end of this guide duct to be connected with exciter base for supporting by flange and to be communicated with, the other end to be connected with generator pit by flange and to communicate with the Power generator fan zone of positive pressure in support.
Described exciter base for supporting is case structure, and be laid with crisscross in it and form the gusset of the inner wind inlet channel of exciter and exhaust air flue, base top cover is provided with duct outlet and air inlet of air duct.
Described exciter shield base is provided with outer cover air inlet and outer cover air outlet, being communicated with the duct outlet that base top cover is arranged is corresponding with air inlet of air duct respectively into and out of air port on this outer cover.
Described base end plate is provided with end plate air outlet, and the air inlet that this end plate air outlet encourages end end cap by generator is communicated with the negative pressuren zone of Power generator fan in support.
The ventilation cooling type generator exciter supporting structure made according to such scheme, the connection of holding end cap is encouraged by exciter base for supporting and generator, and the connection of base and exciter outer cover, ensure that three parts can convenient, flexiblely separately remove and install, reach exciter and encourage end bearing and open and inspect practical function easily.And ventilation and heat is carried out in the air channel, inside formed by the gusset arranged in exciter base for supporting in structure, make exciter no longer wind-engaging transportation work style resistance restriction, its result of ventilating heat dissipation is good.By the setting of this structure, effectively can shorten the integrally-built length of exciter support, while ensureing the rigidity of structure, it also avoid the mutual interference between parts simultaneously, achieve separate unification mutually again between generator main frame and exciter, the technique effect of compact conformation.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, ventilation cooling type generator exciter supporting structure of the present utility model, comprise and send out exciter base for supporting 3, exciter guide duct 2 and exciter outer cover 4, wherein, exciter base for supporting 3 is arranged on generator by base end plate 7 and encourages on the installed surface of end end cap 1 lower outer setting, on the top of exciter base for supporting 3, exciter outer cover 4 is housed, bottom is provided with exciter guide duct 2, one end of this guide duct to be connected with exciter base for supporting 3 by flange and to be communicated with, the other end to be connected with generator pit 5 by flange and to communicate with the Power generator fan zone of positive pressure in support.Described exciter base for supporting 3 is case structure, be laid with crisscross in it and form the gusset 6,12,13,14,15,16,17,18 of the inner wind inlet channel 20 of exciter and exhaust air flue 11, the top cover of exciter base for supporting 3 is provided with duct outlet 19 and air inlet of air duct 10.Described exciter outer cover 4 bottom is provided with outer cover air inlet and outer cover air outlet (not shown), and this outer cover is communicated with the duct outlet 19 that base top cover is arranged is corresponding with air inlet of air duct 10 respectively into and out of air port.Described base end plate 7 is provided with end plate air outlet 9, and the air inlet that this end plate air outlet 9 is encouraged on end end cap 1 by generator is communicated with the negative pressuren zone of Power generator fan in support 5.
Operation principle: the outer cover air inlet bottom exciter outer cover 4 communicates with the duct outlet 19 in exciter base for supporting 3, the outer cover air outlet bottom exciter outer cover 4 communicates with the air inlet of air duct 10 in exciter base for supporting 3.First the cold wind of Power generator fan zone of positive pressure enter the wind inlet channel 20 in exciter base for supporting 3 by the manhole 8 of exciter guide duct 2 on gusset 6, then exciter outer cover 4 is entered by base duct outlet 19, to the exciter in it, permanent magnetic motor carries out heat of cooling exchange, complete after heat exchange again by the exhaust air flue 11 in exciter base for supporting 3, and encourage by the end plate air outlet 9 on the base end plate 7 of exciter base for supporting 3 and exciter the negative pressuren zone that the air inlet on end end cap 1 enters Power generator fan and complete wind path circulation, hence improve the result of ventilating heat dissipation of exciter.Adopt exciter support of the present utility model, its installing/dismounting simple and flexible, exciter and encourage end bearing and open and inspect conveniently, and can separate unification again between generator main frame and exciter, compact conformation.And effectively can solve bearing and oil inlet and oil return pipe is easily interfered, the end vibration problem such as large encouraged by generator.
