Detailed Description

The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the invention provides a low-loss high-load amorphous alloy transformer, which comprises a bottom plate 1 and two brackets 2 symmetrically and fixedly connected to two sides of the top of the bottom plate 1, wherein each bracket 2 is provided with a side supporting assembly 3, and the tops of the two side supporting assemblies 3 are provided with a top pressing plate 4;

the side supporting component 3 comprises an adjusting screw 301 inserted into the support 1, a driving threaded seat 302 sleeved on the adjusting screw 301 in a threaded manner in sequence, and a pressure threaded seat 303, wherein one side of the driving threaded seat 302 is movably connected to one side of each of the two supports 2, the pressure threaded seat 303 is positioned between the two supports 2, one side of the pressure threaded seat 303 far away from the driving threaded seat 302 is movably connected with a connecting sleeve plate 304 sleeved with the adjusting screw 301, the side wall of the connecting sleeve plate 304 is symmetrically and movably connected with a plurality of pressure rods 305, one end of each pressure rod 305 is movably connected with a pressure slide block 306, one end of the adjusting screw 301 is movably connected with a side pressure plate 307 connected with the top pressure plate 4, one side of the side pressure plate 307 is provided with a plurality of sliding grooves 308 corresponding to the pressure slide block 306, one side of the side pressure plate 307 is fixedly connected with a guide rod 309, and one end of the guide rod, Bracket 2 to the other side.

When the transformer body clamping device is used, the side supporting assemblies 3 are used for clamping two sides of the transformer body, and the bottom plate 1 and the top pressing plate 4 are used for clamping the other two sides of the transformer body.

The transformer body is placed on the bottom plate 1 between the two brackets 2, then the driving threaded base 302 is rotated, and the driving threaded rod 302 is movably connected with the brackets 2, so that the adjusting screw 301 is driven to drive the side plates 307 to move towards the direction of the transformer body until the two side plates 307 are tightly abutted against the transformer body.

The adjusting screw 301 is driven by the two driving screw sockets 302, so that the two side plates 307 clamp the transformer body, but the force application point of the adjusting screw 301 is located at the center position of the side plates 307, and the pressing force of the edges of the side plates 307 on the transformer body is different from the center position.

At this time, the pressure screw seat 303 is rotated, and since the position of the adjusting screw 301 cannot be adjusted, the adjusting screw 301 cannot be driven to rotate by rotating the pressure screw seat 303.

After rotating, the pressure threaded seat 303 gradually moves towards the side plate 307 along the axis of the adjusting screw 301, the connecting sleeve plate 304 movably connected with the pressure threaded seat 303 is driven to also move towards the side plate 307, and along with the movement of the connecting sleeve plate 304, the pressure slider 306 is driven by the pressure rod 305 to move along the corresponding sliding chute 308, so that the pressure slider 306 moves to the other side along the corresponding sliding chute 308 until the pressure slider 306 abuts against the other side of the sliding chute 308.

The pressure is applied to the periphery of the side plate 307 by the pressure screw base 303, and the force is transmitted to the pressure slider 306 by the pressure rod 305, so that the pressure slider 306 has a pressure to the side plate 307, thereby applying the force to the edge of the side plate 307.

And because the pressure slider 306 applies the pressure to the side plate 307 symmetrically, the pressure obtained at each edge of the side plate 307 is the same, so that the transformer body is uniformly clamped, and the middle part to the edge of the transformer body is uniformly changed, so that no gap is formed on the surface of the transformer body, and the deformation of the winding is avoided, and the reactance of the transformer is not influenced.

The top press plate 4 comprises a press plate body 401 and two guide grooves 402 symmetrically formed in the press plate body 401, and a locking bolt 403 in threaded connection with the top of the side press plate 307 is slidably connected in each guide groove 402.

And the top pressing plate 4 clamps the top of the transformer body after the side clamping assembly 3 finishes clamping the transformer body.

The top pressing plate 4 has different bodies, the side plate 307 moves to drive the locking bolt 403 to move along the guide groove 403, and when the side plate 307 finishes clamping the transformer body, the locking bolt 403 is screwed down, so that the whole transformer body is clamped.

The number of the sliding grooves 308 is four, the sliding grooves 308 are formed along the diagonal line of the side pressure plate 307, and each sliding groove 308 is connected with a corresponding pressure sliding block 306 in a sliding manner.

The four chutes 308 are disposed at four corners of the side plate 307, so that the side plate 307 can apply force to the transformer body uniformly, and a gap is not formed between the side plate and the transformer body.

A limit plate 5 is fixedly connected to one end of the adjusting screw 301 far away from the side pressure plate 307.

The limiting plate 5 is arranged to prevent the adjusting screw 301 from moving excessively and being disconnected from the driving threaded rod 302.

The side of the sliding groove 308 away from the adjusting screw 301 is tapered, and one end of the corresponding pressure slider 306 matches with the tapered side wall of the sliding groove 308.

The tapered arrangement makes the area of the force applied by the pressure slider 306 to the side plate 307 larger, and also obtains higher stability, and the clamping of the side plate 307 to the transformer body is more stable.

The opposite sides of the two supports 2 are provided with micro-motion grooves 6, the two ends of the top pressing plate 4 are connected in the corresponding micro-motion grooves 6 in a sliding mode, and the shortest distance between the top pressing plate 4 and the bottom plate 1 is the same as the height of the side pressing plate 307.

The micro-groove 6 is arranged to enable the top pressing plate 4 to have a micro moving space along the up-down direction, so that the transformer body can be accommodated and clamped after being accommodated by the size larger than that of the transformer body when the transformer body is placed, and the transformer body is prevented from interfering with the top pressing plate 4 at the height position.

The shortest distance between the top pressing plate 4 and the bottom plate 1 is the same as the height of the side pressing plates, namely, the top pressing plate 4 clamps the transformer body, the top of the side plate 307 abuts against the top pressing plate 4, the bottom of the side plate 307 abuts against the bottom plate 1, and no space exists after the transformer body is clamped, so that the winding is deformed, and the reactance of the transformer is influenced.

The connection point of the pressure rod 305 and the pressure slider 306 is located at the middle position of the side of the pressure slider 306 away from the slide groove 308.

The connection position of the pressure rod 305 and the pressure slider 306 is located in the middle of the pressure slider 306, so that when the pressure transmitted by the pressure rod 305 is applied to the pressure slider 306, the pressure obtained by the pressure slider 306 as a whole is relatively uniform, the pressure applied by the pressure slider 306 to the side plate 307 is also uniform, and the problem of no force action or small force interaction between the part of the pressure slider 306 and the side plate 307 can be avoided.

The longest distance between the connecting sleeve plate 304 and the side pressing plate 307 is larger than the length of the sliding chute 308.

Ensuring that the pressure slider 306 is already against one side of the runner 308 before the connecting strap 304 contacts the side plate 307 ensures that the pressure slider 306 has sufficient force applied to the side plate.

The shortest distance between one end of the guide rod 309 far away from the side pressure plate 307 and the bracket 2 is equal to the longest distance between the limit plate 5 and the driving threaded seat 302.

After the adjusting screw 301 is moved to the maximum distance, one end of the guide rod 309 is still not separated from the bracket 2, so that the guide rod 309 can be used for limiting and guiding the connecting sleeve plate 304 normally.

The acute angle formed by the pressure bar 305 and the pressure slider 306 is not more than 45 degrees.

When the acute angle is large, the separation of the force applied by the pressure rod 305 to the pressure slider 306 along the moving direction of the side plate 307 is smaller, that is, the clamping force of the pressure slider 306 to the side plate 307 is smaller, which is not favorable for clamping the side plate 307, so that the range of the acute angle is limited, and the pressure applied to the side plate 307 is as large as possible.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
