Abstract
The utility model relates to an insulating supporting device for the electrical ageing test of a large-scale generator stator bar, composed of a supporting plate and pressure plates, wherein the supporting plate has a trapezoid structure, the bottom is provided with a trapezoid groove; the left and right sides of the supporting plate is symmetrically provided with eight U shaped grooves from top to bottom, the supporting plate and the pressure plates are combined by using bolts, and the supporting plate is provided with multiple screwed holes; and each of the pressure plates has a rectangular structure. Two supporting plates, a first pressure plate and a second pressure plate are combined to form a set of supporting device, the left and right sides of the supporting plates are symmetrically provided with six horizontal portions from top to bottom, and bolts pass through the pressure plates and are combined to the support plates. Each single body of the insulating supporting device has the same structure and dimension, an article to be tested can be horizontally arranged, without being affected by any other external force during the test process, and the test space is greatly saved.
Description
Technical field: the utility model relates to a kind of large generator stator bar electrical ageing test and uses insulation support device
Background technology: be the anti-deterioration ability of check insulation system under the electric stress effect, need stator bar is carried out electrical ageing test.Because test product will bear high-tension effect in process of the test, therefore should test product be placed on the good insulation support device of electric durability ability; Because bracing or strutting arrangement need be born the total weight of test product, therefore device should have rational structure and good mechanical property.Traditional electrical ageing test has following shortcoming with insulation support device:
1) because project organization unreasonable, test product can only be horizontal during electrical ageing test, needs bigger test space.2) do not adopt modular design; All design separately to each test product; Waste of manpower greatly and material resources 3) along with the direction of genset to maximization, hugeization, air coolingization; The size and the weight of test product are increasing, and trial voltage is also increasingly high, and the structure of original insulation support device can't have been born the effect of high mechanical stress and high electric stress.
Therefore, need exploitation large generator stator bar electrical ageing test to use insulation support device.
Summary of the invention: the purpose of the utility model is that exploitation is practical, safe large generator stator bar electrical ageing test is used insulation support device, to use as the electrical ageing test of various sizes line rod.The technical scheme of the utility model is: a kind of large generator stator bar electrical ageing test is used insulation support device, is made up of back up pad and pressing plate, and back up pad is a trapezium structure, and the bottom has dovetail groove; The left and right sides of back up pad is arranged with eight U type grooves from top to bottom; Back up pad and pressing plate carry out bolt closing; Back up pad has a plurality of threaded holes, and pressing plate is rectangular configuration, the pressing plate of two back up pads and first pressing plate, two kinds of specifications of second pressing plate with bolt setting up into a cover bracing or strutting arrangement jointly; Back up pad left and right sides symmetric design from top to bottom is six horizontal components, and bolt is passed pressing plate being incorporated on the back up pad.
The utlity model has following advantage:
1, adopt modular design, each monomer has identical structure and size, and test product can horizontal positioned, in process of the test, does not receive the influence of other any external force.
2, behind the vertical notching construction of employing, test product can vertically be placed, and compares with original horizontal positioned mode, has saved test space greatly.

Embodiment:
The utility model is that a kind of large generator stator bar electrical ageing test is used insulation support device, is made up of back up pad and pressing plate, and back up pad is trapezium structure, and is as shown in Figure 1, and the bottom has dovetail groove 1; The left and right sides of back up pad is arranged with eight U type grooves 2 from top to bottom; Back up pad and pressing plate carry out bolt closing, and back up pad has a plurality of threaded holes 3, and pressing plate is rectangular configuration; As shown in Figure 4; Setting up into a cover bracing or strutting arrangement 4 jointly, back up pad left and right sides symmetric design from top to bottom is six horizontal components to the pressing plate of two back up pads and first pressing plate, two kinds of specifications of second pressing plate, and bolt is passed pressing plate being incorporated on the back up pad with bolt.As shown in Figure 2, four jiaos of place's symmetries of first pressing plate have four through holes 5; As shown in Figure 3, second pressing plate has two through holes 6 along the horizontal center line symmetry.
According to shape shown in Figure 1, be base material process support plate with the laminated epoxy glass-cloth board; According to Fig. 2 and shape shown in Figure 3, be the pressing plate of two kinds of specifications of base material processing with the laminated epoxy glass-cloth board; Back up pad left and right sides symmetric design from top to bottom is six horizontal components, and bolt is passed pressing plate being incorporated on the back up pad.
