Abstract
The invention relates to an insertion assembly method for an inner stator and an outer stator of a large generator. The method is characterized by comprising the following steps of: horizontally arranging and fixing the outer stator, horizontally slowly pulling the inner stator to make the inner stator slowly slide into the outer stator, lifting the inner stator to a required assembly position by using a jack after the inner stator is assembled in place in an insertion way, and welding and fixing a spring plate on the inner stator and a corresponding support structure of the outer stator to finish the whole insertion assembly process. The insertion assembly method provided by the invention is unconstrained by the highest bearing capacity of an insertion assembly tool; a special tool used for insertion assembly is simple; the circumference, concentricity and the like of the inner and outer stators are not required to be corrected and adjusted in the insertion assembly; the insertion assembly process is simple, easy and highly operable; and after the insertion assembly is finished, the whole stator is not required to be turned over.
Description
Technical field
The present invention relates to a kind of internal stator of high-rating generator and the method that installs between the external stator.
Background technology
External stator installs the two kinds of methods that mainly contain in original turbo generator:
The first is that interior external stator vertically installs.Electricity generator stator stand (being external stator) is vertically placed on installs on the station, sling stator core (being internal stator) to the out frame top with lifting device.After the stator iron core is stable, slowly puts down stator core and adjust simultaneously the circumferential position of stator core and out frame, concentricity and magnetic center position.Install after putting in place the respective support structure welding of the latch plate in the stator core and out frame is fixed, finally finish interior external stator and install.The method needs hoisting tool special, in installing process, need constantly to adjust the circumferential position, concentricity of stator core and out frame etc., and installing also needs once to stand up whole stator after finishing, and need to join in addition special use and stand up instrument, requires high to instrument and the maximum lift heavy of driving.
The second be interior external stator level install-external stator is inserted in internal stator.Generator stator core (being internal stator) is placed horizontally on the instrument of installing, adjust the stator core levelness, lifting out frame (being external stator) level is inserted in stator core lentamente, it is concentric with out frame to install the rear adjustment stator core that puts in place, and the respective support structure welding of the latch plate in the stator core and out frame fixed, finally finish interior external stator and install.The method is limited to the maximum of the instrument of installing and bears weight, installs for high-rating generator to have limitation.
Summary of the invention
The purpose of this invention is to provide the interior external stator of a kind of high-rating generator and install method, make high-rating generator install the restriction that is not subjected to install the conditions such as instrument, and the process that installs is simple and easy, handling good.
In order to achieve the above object, technical scheme of the present invention has provided the interior external stator of a kind of high-rating generator and has installed method, it is characterized in that step is:
Step 3, by jack internal stator is lifted to the rigging position that needs, at last the respective support structure welding of the latch plate on the internal stator and external stator is fixed.
Preferably, on described the first guide rail and described the second guide rail, scribble respectively lubricant.
Preferably, described the first guide rail and described the second guide rail are made by different materials.
The method that installs provided by the invention is not installed the restriction that the instrument maximum is born weight, the specific purpose tool of using in installing is simple, need not the school in installing and transfer inside and outside stator circumference, concentric etc., and the process that installs is simple and easy, handling good, install finish after whole stator need not to stand up.

Fig. 1 is schematic diagram in the internal stator moving process;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the internal stator rear schematic diagram that puts in place.
Embodiment
For the present invention is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
External stator installs method in a kind of high-rating generator provided by the invention, and step is:
Step 3, as shown in Figure 3 is lifted to the rigging position that needs by jack 9 with internal stator 1, at last the respective support structure welding of the latch plate on the internal stator 1 and external stator 2 is fixed.
Claims (3)
1. the interior external stator of high-rating generator installs method, it is characterized in that step is:
Step 1, the first guide rail (6) of packing in the bottom of internal stator (1), the second guide rail (7) of in external stator (2), packing into, with external stator (2) horizontal positioned and fixing, at a side horizontal positioned bracing frame (3) of external stator (2), bracing frame (3) is near external stator (2);
Step 2, internal stator (1) is erected on the bracing frame (3), one end of steel wire rope (5) is connected on the internal stator (1), the other end passes fixed pulley (4), pulling steel wire rope (5) makes internal stator (1) level slowly mobile, in the time of in internal stator (1) moves to external stator (2), the first guide rail (6) drops on the second guide rail (7), continues pulling steel wire rope (5), puts in place until internal stator (1) installs;
Step 3, by jack (9) internal stator (1) is lifted to the rigging position that needs, at last the respective support structure welding of the latch plate on the internal stator (1) and external stator (2) is fixed.
2. external stator installs method in a kind of high-rating generator as claimed in claim 1, it is characterized in that: scribble respectively lubricant (8) on described the first guide rail (6) and described the second guide rail (7).
3. external stator installs method in a kind of high-rating generator as claimed in claim 1, it is characterized in that: described the first guide rail (6) is made by different materials with described the second guide rail (7).
