The device provided by the utility model overcomes defects in the prior art and has the better vibration-isolation effect and the better mechanical property, an elastic connection between the stator iron core and the machine seat is achieved, and running reliability of a generator is improved.
Description
Technical field
The utility model relates to a kind of generator unit stator vibration insulation structure, for improving the vibration isolating effect between generator stator core and support, belongs to stator of steam turbine generator technical field.
Background technology
In Generator Stator design, vibration insulation structure is to realize out frame and the important component part being connected unshakable in one's determination, vibration insulation structure can not only support generator stator core and line rod, and can effectively reduce stator core vibrating to out frame transmission, also intercept by unit basis and transmit to the vibration of stator core by out frame.
The principle of large turbo-type generator vibration insulation structure is between iron core and support, to adopt latch plate structure to realize to connect.Because the connected mode of current iron core, support and latch plate is mainly with bolts, under generator long-time running condition, may there is bolt looseness, thereby affect the anti-vibration performance of stator, even affect the security reliability of generator.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of generator unit stator vibration insulation structure that can effectively improve vibration isolating effect between generator stator core and support, guarantee the security of operation of generator.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of generator unit stator vibration insulation structure, it is characterized in that: comprise generator stator core, generator stator core is located in the clamping ring unshakable in one's determination of arranging vertically, each clamping ring unshakable in one's determination is welded and fixed by connecting bulge loop and latch plate, and the mesospore of latch plate both sides and out frame is welded and fixed.
Preferably, described clamping ring unshakable in one's determination is 4～8.
Preferably, 3 described latch plates are located at respectively the left and right sides and the bottom of described clamping ring unshakable in one's determination.
The generator unit stator vibration insulation structure that the utility model provides is that to utilize clamping ring to hold shape unshakable in one's determination tightly by support bar in aggregates, clamping ring is welded and fixed by connecting bulge loop and latch plate, latch plate and support mesospore are also welded and fixed, and finally make iron core be fixed in support.
The device that the utility model provides has overcome the deficiencies in the prior art, and the elasticity having realized between stator core and support connects, and has better vibration isolating effect and mechanical property, has improved the operational reliability of generator.
Accompanying drawing explanation
The generator unit stator vibration insulation structure schematic diagram that Fig. 1 provides for the utility model;
Fig. 2 is generator unit stator vibration insulation structure circumferential arrangement schematic diagram.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The generator unit stator vibration insulation structure schematic diagram that Fig. 1 provides for the utility model, described generator unit stator vibration insulation structure is by generator stator core 1, and clamping ring 2 unshakable in one's determination, connects bulge loop 4, and latch plate 3 and out frame 5 form.Generator stator core 1 is fixed in the clamping ring unshakable in one's determination 2 of arranging vertically 4～8, each clamping ring 2 unshakable in one's determination is welded and fixed with latch plate 3 by connecting bulge loop 4, the mesospore of latch plate 3 both sides and out frame 5 is welded and fixed, thereby having realized stator core 1 is connected with the elasticity of out frame 5, make generator unit stator there is better vibration isolating effect and mechanical property, guarantee the security of operation of generator.
Figure 2 shows that the generator unit stator vibration insulation structure circumferential arrangement schematic diagram that the utility model provides, 3 latch plates 3 are distributed in the left and right sides and the bottom of clamping ring 2 unshakable in one's determination, and each clamping ring 2 unshakable in one's determination is by connecting bulge loop 4 and being welded and fixed with 3 latch plates 3.
The generator unit stator vibration insulation structure that the utility model provides, the elasticity having realized between stator core and support connects, and structure is fixing reliable, has better vibration isolating effect and mechanical property, has improved the operational reliability of generator.
