Embodiment
The outside drawing of existing gearcase (1) as shown in Figure 1, its top is provided with cover plate (2).The inside of gearcase is provided with the transmission mechanism of helical gear or worm and wormwheel.
Present embodiment as shown in Figure 2 has been set up position indicating mechanism (3) on the cover plate of gearcase (1).
The intraware erection sequence of position indicating mechanism as shown in Figure 4 is:
1. at first shift fork (33) is connected with elastic cylindrical pin with rotating shaft (34);
2. two bearings (35) are knocked in position indicating mechanism pedestal (31) and fix with circlip for hole;
3. shift fork and rotating shaft are driven in bearing and fix with circlip for shaft from base bottom surface;
4. ring gear I (36) is fixed on the pedestal;
5. pinion (38) is assembled with pivoted arm (37) and be connected with rotating shaft with key;
6. be enclosed within the rotating shaft after ring gear II (39) and rotating disk being screwed;
7. indicating dial (41) is fixed on the pedestal;
8. pin I (42) is screwed on rotating disk (40);
9. pointer II (43) is screwed in rotating shaft;
10. above pedestal, put circular glass observation window and rubber slab and cover (32) and compress with observation window.
In the embodiment shown in fig. 4, use the planetary gear principle, when rotating shift fork, rotating shaft is rotated together, and rotating shaft rotates pivoted arm and pinion with the key connection of pivoted arm; The ring gear I number of teeth that is fixed on the pedestal is 70 teeth, and the ring gear II number of teeth that is fixed on the rotating disk is 72 teeth; Pinion places between ring gear I and the ring gear II, so when rotating shaft drive pivoted arm and the moving circle of pinion revolution, because the ring gear I is fixed on the pedestal and can not rotates, the ring gear II just turns over 1/36 at the uniform velocity slowly and encloses; Such result is exactly the moving circle of pointer II revolution that is fixed in the rotating shaft, is fixed on the pin I to be turned over 1/36 circle on the rotating disk, conforms to fully with the position indicating mechanism motion of motor mechanism box.
The position indicating mechanism as shown in Figure 3 and the connection of gearcase only need be bored a hole with drill bit at correct position on helical gear in the original gearcase or worm gear, squeeze into an elastic cylindrical pin (11) then and stay suitable length; Behind the groove aligning elastic cylindrical pin (11) with the position indicating mechanism shift fork (33) that assembles position indicating mechanism and gearcase are lumped together and be screwed; This moment, positive counter-clockwise both direction was rotated the rotating shaft on the transmitting gear box, if the pointer II of position indicating mechanism is also rotated simultaneously, just explained that shift fork docks accurately with elastic cylindrical pin.
Have the gearcase of position deixis on switch, install and original gearcase just the same, only need after the debugging of switch gear finishes, open the observation window lid, just pin I and pointer II are adjusted to switch gear correspondence and are got final product.
In the transformation of the gearcase at user place, need not change gearcase, as long as prepare simple tools and spare part, as: spanner, tape measure, electric drill, elastic cylindrical pin; Under the situation that transformer has a power failure; Pull down the gearcase cover plate with spanner; On helical gear in gearcase or the worm gear with the good size of tape measure amount; Electricity consumption is drilled in correct position and bores a hole, squeezes into an elastic cylindrical pin and stays suitable length, behind the groove aligning elastic cylindrical pin with the position indicating mechanism shift fork that assembles position indicating mechanism and gearcase is lumped together and is screwed; Then according to the indication adjustment of the gear on the motor mechanism box with pin I and pointer II, guarantee with motor mechanism box on gear indicate after consistent pointer is fastening; Last manually or the electric operating motor mechanism box, observe on the motor mechanism box with gearcase on gear indication rotation direction rise or fall and the position of pointer, confirms errorless after, observation window covered compress.
The benefit of this modification scheme is that transformer need not suspended core, and switch need not be drained the oil, and the connection between switch and the motor mechanism box need not be broken off, and workload is little, and all work can be above one hour.The transformer interruption duration is short; After the most important meaning of this modification scheme is embodied in transformation; When motor mechanism box needs repairing or changes; After connection between switch and the motor mechanism box is broken off; No matter whether the user has changed the gear of switch and motor mechanism box, need only rotating switch upper reversing gear box or motor mechanism box when connecting again, make its position indication unanimity just can guarantee positive connection.In securing member accidental release sometimes, the connection between switch and the motor mechanism box is broken off, at this moment operating motor structure case again; Will cause the actual-gear of switch and motor mechanism box inconsistent; If this moment, switch did not have the position indication, and the user must cause serious consequence just simply with its fastening again connection; The lighter damages switch, and weight person causes the transformer major accident.This all is to take place that warning taken from the overturned card ahead was arranged in the past.
Even there is the gearcase of position deixis on the switch that the position indication is arranged, to use superiority is arranged also; What the position indication indication on the switch relied on is the motion of Geneva mechanism; The position indication of every adjacent gear is fast-changing; Have any different with the indication of the position of motor mechanism box, need guarantee through the number of turns of adjustment motor mechanism box both forward and reverse directions when therefore connecting, this is in switch manufacturer specialty relatively; But arrived transformer producer and Subscriber Unit and will therefore can not guarantee to be connected to optimum state with how many decisions of its experience.On gearcase, increase the position deixis, as long as when switch dispatches from the factory, adjust, with the installation that greatly facilitates on transformer.
Position indicating mechanism adopts the planetary gear motion principle, and the speed no-load voltage ratio is big, is 1:36, and is simple and reliable for structure, and good looking appearance is observed convenient directly perceived.Particularly utilized original gearcase, the part of increase is few, and improvement cost is low.
