Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of special spanner of sub-connecting switch of transformer.
Background technology
The effect of the shunting switch of transformer is the size regulating transformer output voltage, to adapt to the change of line voltage and to meet the requirement of load voltage.It is on a certain winding of transformer, extract suitable point new head out, and conversion divides the number of turn just changing winding during new head, thus changes the turn ratio of Transformer Winding, changes voltage ratio, also just changes output voltage.And transformer is when changing shunting switch, common wrench is difficult to shunting switch to take off.
China patent CN202572241U discloses a kind of Special spanner for transformer tap switch, and it comprises handle, connecting rod and box spanner; The two ends of described connecting rod connect described handle and described box spanner respectively; A shrinkage pool is provided with bottom described box spanner.Described shrinkage pool medial surface comprises two planes be parallel to each other.Described box spanner profile is cylinder.The advantages such as this Special spanner for transformer tap switch has design science, practical, operating efficiency is high, easy to operate.
But because each parts of inside transformer arrange comparatively compact, narrow space, environment is comparatively complicated.Pinch bar in above-mentioned patent is fixed on connecting rod, and the two ends of handle are all along the identical distance that extends radially outwardly of spanner, assuming that this segment distance is L, in the layout environment of sub-connecting switch of transformer, probably the space length of shunting switch side is less than L, and opposite side space length is greater than L, and above-mentioned spanner so just may be caused to be stuck cannot be operated, thus reduce the versatility of spanner, the various complex environments in transformer can not be adapted to well.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, and provide a kind of special spanner of sub-connecting switch of transformer, technical problem to be solved in the utility model is: the versatility how improving this spanner.
The purpose of this utility model realizes by following technical proposal:
A kind of special spanner of sub-connecting switch of transformer, described spanner comprises cylindrical body, one end of described body have can with the hole clipping of sub-connecting switch of transformer phase clamping, it is characterized in that, the sidewall of described body offers through hole one and through hole two, coaxial and both axis of described through hole one and through hole two is all arranged along the radial direction of described body; Described spanner also comprises the handle of a column, the diameter of described handle is less than the internal diameter of described through hole one and the internal diameter of through hole two, one end of described handle is successively through described through hole one and through hole two and the nut that has been threaded, and the external diameter of described nut is greater than the internal diameter of described through hole two.
Its operation principle is as follows: the hole clipping of body one end in use, can be socketed on sub-connecting switch of transformer by the Special spanner for transformer tap switch in the utility model; Diameter due to handle is less than the internal diameter of through hole one and the internal diameter of through hole two, therefore handle can slide in through hole one and through hole two, during concrete operations, the specific environment in visual transformer around shunting switch, the relative position correspondingly between regulating handle and body; Assuming that the length that handle one end extends out in through hole two is L2, the length that handle one other end extends out in through hole one is L1, space length maximum around shunting switch is Lmax, minimum of a value is Lmin, as Lmin>L1+L2, then this spanner in use can according to the relative position between the random regulating handle of the use habit of operator and body; As L1+L2>Lmin>(L1+L2)/2, then by the relative position between regulating handle and body, make L2 all be less than Lmin; Particularly as Lmin<(L1+L2)/2 time, spanner in documents obviously will be stuck by the space constraint around proximity switch due to non-adjustable, and the spanner in the utility model still makes L2 be less than Lmin by the relative position between regulating handle and body, external diameter due to nut is greater than the internal diameter of through hole two, the lateral wall of nut and body therefore now can be made to lean and carry out spacing handle of avoiding from slippage in body.In sum, compared with documents, spanner in the utility model adapts to multiple different environment by the relative position between regulating handle from body, versatility is better, and operator also can according to the relative position self needing to come between regulating handle and body to cater to respective operating habit.And nut external diameter described in the utility model, be the generic term of those skilled in the art, specifically can with reference to the nut external diameter described in China patent CN203080312U.
In the special spanner of above-mentioned a kind of sub-connecting switch of transformer, the internal diameter of described through hole one is equal with the internal diameter of described through hole two.The internal diameter of through hole one and through hole two is equal, can improve the convenience adding man-hour, when holing by drilling machine one-shot forming, improves working (machining) efficiency.
In the special spanner of above-mentioned a kind of sub-connecting switch of transformer, the sidewall of the described handle other end offers the external screw thread that can be connected with described nut thread.The handle other end is designed with external screw thread, then operator can consider whether set up a nut at this section of external screw thread place, avoid handle from slippage in body further in use as required; And this section of external screw thread is designed to match with nut, be to improve its replaceability.
In the special spanner of above-mentioned a kind of sub-connecting switch of transformer, described hole clipping is a waist-shaped hole.Hole clipping is designed to waist-shaped hole, two phase planes of waist-shaped hole can be made to contact thus turn shunting switch with the both sides of shunting switch.
In the special spanner of above-mentioned a kind of sub-connecting switch of transformer, the length of described body is greater than the length of described handle.The length of body is greater than the length of handle, the turn of handled easily person, and when avoiding operator's turn spanner, fist portion can touch contact-making switch.
In the special spanner of above-mentioned a kind of sub-connecting switch of transformer, the sidewall of described body offers auxiliary through hole one and auxiliary through hole two along the length direction of body, described auxiliary through hole one and auxiliary through hole two all have two, coaxial and both axis of described two auxiliary through hole one is all arranged along the radial direction of described body, coaxial and both axis of described two auxiliary through hole two is all arranged along the radial direction of described body, and the internal diameter of described auxiliary through hole one and the internal diameter of auxiliary through hole two are all equal with the internal diameter of described through hole one.After being designed with auxiliary through hole one and auxiliary through hole two, improve the versatility of this spanner further, handle is plugged in auxiliary through hole one or auxiliary through hole two by the visual specific environment of operator.
Compared with prior art, the utility model has the following advantages:
1, the spanner in the utility model adapts to multiple different environment by the relative position between regulating handle from body, versatility is better, and operator also can according to the relative position self needing to come between regulating handle and body to cater to respective operating habit;
2, after being designed with auxiliary through hole one and auxiliary through hole two, improve the versatility of this spanner further, handle is plugged in auxiliary through hole one or auxiliary through hole two by the visual specific environment of operator.
