Description

Technical Field

[0001] The utility model relates to the field of fixing devices, in particular to a fixing device for a transformer high voltage coil. Background Art

[0002] In electrical equipment and wireless circuits, dry-type transformers are often used for voltage increase and decrease, impedance matching, safety isolation, etc. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance. There are many components of the transformer structure, the most important of which is the coil. For transformers, the installation and fixation of the coil is particularly important.

[0003] The existing method is to directly embed the coil into the fixing sleeve when installing it. When fixing it, the two springs are used to push the limit block to achieve the purpose of fixing the coil. It is easy to disassemble and assemble, and it is easy to repair if there is a problem. It will not damage the equipment and affect the normal use of the equipment. It has high economic benefits and strong practicality. The equipment is provided with an active buckle and a fixing buckle. When fixing it, it is directly pressed to bend the active buckle and then buckled on the fixing buckle.

[0004] However, the number of coil groups of existing high-voltage coils varies, and the existing fixing structure is fixed by snapping on the entire exterior of the high-voltage coil, rather than snapping on each coil group individually. When snapping on coils of different numbers, the pressing will be uniform and flat, resulting in unstable fixing. Utility Model Content

[0005] The utility model aims to provide a transformer high-voltage coil fixing device, which is used to solve the problem that the number of coil groups of existing high-voltage coils are different. The existing fixing structure is fixed by snap-on fixing on the overall outside of the high-voltage coil, but each group of coils is not fixed by snap-on fixing separately. When snap-on fixing coils of different numbers, the pressure covering will be uniform and flat, resulting in the problem of unstable fixing.

[0006] Therefore, the utility model provides a transformer high-voltage coil fixing device, including a top plate and a high-voltage coil, wherein the high-voltage coil is installed between the top plates, and the front and rear ends of both sides of the top plates are provided with distance adjusting mechanisms that can adjust the distance of the fixing component, and a clamping mechanism for disassembling and replacing the fixing component is provided between the distance adjusting mechanisms.

[0008] Preferably: the clamping mechanism includes an outer plate and a slot, a fixing rod is installed in the slot, a spring is mounted on the outer wall of the fixing rod, a clamping plate is mounted on the outer wall of the spring, a pull plate is mounted on the outer side wall of the clamping plate, clamping slots are provided on the upper and lower side walls of the outer plate, and a pressure plate is installed on the side of the outer plate close to the high-voltage coil.

[0009] Preferably, the first bevel gear and the second bevel gear are meshed with each other.

[0010] Preferably: the second bevel gear is connected to the screw.

[0011] Preferably, the cross-sectional dimensions of the card plate and the cross-sectional dimensions of the card slot are consistent with each other.

[0012] Preferably, the width of the pull plate matches the width of the slot.

[0013] Preferably, the clamping plate is connected to one end of a spring, and the other end of the spring is connected to the inner wall of the slot.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model fixes high-voltage coils of different coil groups, by pulling the pull plate toward the upper and lower sides, the pull plate drives the card plate to disengage from the card slot and move toward the direction of the fixing rod, and the squeezing spring generates potential energy, and the outer plate can be directly pulled to remove it from between the upper and lower telescopic plates, and the pressure plate with the corresponding number of pressing teeth can be replaced, and the replaced outer plate can be inserted between the upper and lower telescopic plates, and the pulling force on the pull plate is released. The spring releases the potential energy and pushes the card plate to be inserted into the aligned card slot to complete the replacement and fixation, and the control click operation drives the first bevel gear to rotate, and the meshing drives the second bevel gear to rotate, which drives the connected screw to rotate, and the meshing drives the telescopic plate to move into the slide groove, thereby driving the installed pressure plate to move in the direction of the high-voltage coil, so that the high-voltage coil is clamped and fixed front and back, and a firm fixing effect is achieved.
