Abstract
The utility model discloses an on-load tapping changing switch with manual shift mechanism, mainly composed of on-load tapping changing switches. The utility model is characterized in that: the covering plate with on-load tapping changing switch is provided with a manual shift mechanism. The utility model has a reasonable structure and novel idea of adding a function to the original switch structure. One through hole and eight screw holes are additionally arranged on the original switch cover without any change of other structures, so as to facilitate the electroless debugging of transformer with highly promotional value.
Description
Technical field
The utility model relates to the appliance switch technical field, specifically, relates to a kind of on load tap changer.
Background technology
SY ZZ type on load tap changer be electric pressure at 35KV, the tap changer that the distribution transformer of electric current≤400A is the most frequently used is that domestic distribution system is selected more product for use.In at present domestic product, all there is not manual shifting mechanism, make troubles for the nothing electricity debugging of transformer.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, debugs the on load tap changer that has manual shifting mechanism that brings convenience for the nothing electricity of transformer.
For achieving the above object, the utility model adopts following technical scheme: a kind of on load tap changer that has manual shifting mechanism, mainly form by on load tap changer, and it is characterized in that: on the cover plate of on load tap changer, be provided with and move gear mechanism on the other hand.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, it is a function that on former construction of switch, increases, only multi-processing 1 through hole and 8 screws on former switch cover, other structure need not to do any change, brings convenience for the nothing electricity debugging of transformer, has promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model manual shifting mechanism.
Embodiment
Referring to Fig. 1, by screw manual shifting mechanism 200 is arranged on the cover plate of on load tap changer 100.The structure of manual shifting mechanism, referring to Fig. 2, last bevel gear set 202 is installed in the upper reversing gear box 201, and it links to each other with crank 203, from horizontally rotating by this to the bevel gear speedup and turn to vertical rotation of crank.204 groups of following bevel gears are installed on the motor back seat by pinion stand 207, and 206 of bevel pinions are installed in external part 205 behind the motor shaft, and two parts link to each other by middle slot structure 210.The rotating ratio that crank reaches motor shaft is about 3.5 to 1.Wherein, upper reversing gear box 201 vertical shafts are by sealing ring 208 sealings, and upper reversing gear box 201 is sealed by rubber blanket 209 with joint portion, switch cover plane, thereby guarantees that the indoor oil of circuit-breaker oil can not ooze out.The outer rain-proof cover 211 that is provided with of upper reversing gear box then can prevent the pollution to transmission mechanism of rainwater and dust effectively.
Claims (2)
1, a kind of on load tap changer that has manual shifting mechanism mainly is made up of on load tap changer, it is characterized in that: on the cover plate of on load tap changer, be provided with and move gear mechanism on the other hand.
2, by the described a kind of on load tap changer that has manual shifting mechanism of claim 1, it is characterized in that: manual shifting mechanism is made up of upper reversing gear box and upper and lower bevel gear set, last bevel gear set is installed in the upper reversing gear box, it links to each other with crank, following bevel gear set is installed on the motor back seat, bevel pinion then is installed in external part behind the motor shaft, and two parts link to each other by middle slot structure.
