Description

Technical Field

[0001] The present invention relates to the field of high-voltage transformers, and in particular to an electrostatic high-voltage transformer skeleton. Background Art

[0002] As we all know, electrostatic precipitators are very effective in treating industrial pollution. Electrostatic precipitators generate static electricity through high-voltage coils, which are the core components of electrostatic precipitators.

[0003] Currently, the installation of the high-voltage transformer in an electrostatic precipitator is complex. Different electrostatic precipitator housings require different high-voltage transformer installation orientations. Existing technologies only support one installation method, which is inconvenient and lacks versatility. Furthermore, existing high-voltage transformer crimping methods typically use crimping troughs, resulting in a high scrap rate and low production efficiency. Therefore, a new technical solution is urgently needed to address these technical issues.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide an electrostatic high-voltage transformer frame, which solves the technical problems that the electrostatic high-voltage transformer cannot be installed from different directions and the improper wire pressing method leads to low production efficiency.

[0006] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the present invention is: an electrostatic high-voltage coil skeleton, comprising a magnetic core, a primary winding coil skeleton and a secondary winding coil skeleton, the primary winding coil skeleton consisting of a primary coil partition and a primary coil cylinder, the primary coil partition being arranged at both ends of the primary coil cylinder, and primary coil pins being arranged on the end face of the primary coil partition, the primary coil pins being arranged in a symmetrical structure, the front end face of the upper end portion of the secondary winding coil skeleton and the front end face of the lower end portion of the secondary winding coil skeleton are both provided with transversely penetrating grooves, and secondary coil pins are symmetrically arranged in the grooves, the primary coil cylinder is provided with a first hollow structure penetrating longitudinally, and the secondary winding coil skeleton is provided with a second hollow structure penetrating longitudinally, the first hollow structure and the second hollow structure are adapted to the shape of the protrusions on both sides of the magnetic core, and the protrusions are embedded in the first hollow structure and the second hollow structure.

[0007] As a preferred technical solution: a wire pressing groove is correspondingly provided below each secondary coil pin in the groove at the upper end, and a wire pressing groove is correspondingly provided above each secondary coil pin in the groove at the lower end.

[0008] As a preferred technical solution: a boss is provided on the end surface of the primary coil partition, and the primary coil pin is provided on the boss.

[0009] As a preferred technical solution: the junction of the boss and the partition is symmetrically provided with inlet and outlet wire grooves.

[0010] As a preferred technical solution: the first hollow structure and the second hollow structure are square structures, and the protrusion is a square structure and is adapted to the first hollow structure and the second hollow structure.

[0011] As a preferred technical solution: a plurality of secondary coil partitions are provided on the circumferential surface of the secondary winding coil skeleton, and the secondary coil partitions are linearly and evenly arranged and extend toward both ends of the secondary winding coil skeleton.

[0012] As a preferred technical solution: output wire holes are provided on the upper and lower end surfaces of the secondary winding coil.

[0013] As a preferred technical solution: the structures of the primary coil pins and the secondary coil pins are cylindrical or square.

[0014] The beneficial effects of the present invention are:

[0015] 1) The hollow structure of the primary winding coil bobbin is compatible with the protruding structures on both sides of the magnetic core. During installation, the primary winding coil bobbin can be flexibly assembled with the magnetic core according to different installation directions.

[0016] 2) Pins are symmetrically arranged on the top surface of the primary winding coil bobbin and the side surfaces of the secondary winding coil bobbin. The pins have two functions: first, they press the wire during winding. Compared with wire pressing troughs, the overall production efficiency is higher and the scrap rate of finished products is lower. Second, the pins can change the wire pressing method. When winding, any pin can be used as the starting point, which improves winding efficiency while retaining the traditional wire pressing trough to protect the coil.

[0017] 3) Multiple secondary coil partitions are provided on the secondary winding coil frame to prevent the coil from high voltage breakdown. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings;

[0025] Please refer to Figure 1-5 , an electrostatic high-voltage coil skeleton, comprising a magnetic core 1, a primary winding coil skeleton 2 and a secondary winding coil skeleton 3, the corners of the uppermost plane of the primary winding coil skeleton 2 are provided with primary coil pins 4, the primary coil pins 4 are arranged in a symmetrical structure, the front end surface of the upper end 304 of the secondary winding coil skeleton 3 and the front end surface of the lower end 305 of the secondary winding coil skeleton 3 are both provided with transversely penetrating grooves 306, and the secondary coil pins 5 are symmetrically arranged in the grooves 306, the primary coil cylinder 201 is provided with a first hollow structure 205 penetrating longitudinally, and the secondary winding coil skeleton 3 is provided with a second hollow structure 301 penetrating longitudinally, the first hollow structure 205 and the second hollow structure 301 are aligned with the magnetic core 1. The protrusions 101 on both sides are of matching shapes, and the protrusions 101 are embedded in the first hollow structure 205 and the second hollow structure 301. Because the protrusions 101 of the magnetic core 1 are structured to match the first hollow structure 205 and the second hollow structure 301, the primary winding coil bobbin 2 and the secondary winding coil bobbin 3 can be installed in different installation directions when installing the magnetic core 1, and are not limited to a single installation direction. This expands the application range of the electrostatic high-voltage transformer. The primary coil pins 4 and the secondary coil pins 5 can provide different winding methods, improving production efficiency. Compared with traditional wire pressing grooves, the pins have a better wire pressing effect. The secondary coil pins 5 are arranged in the groove 306 to protect the winding and the secondary coil pins 5, thereby improving the wire pressing effect and reducing the coil scrap rate.

[0026] like Figure 1-5 As shown, a wire pressing groove 303 is correspondingly provided near each secondary coil pin 5 on the secondary winding coil frame 3. The wire pressing groove 303 is retained to provide a traditional wire pressing method. The wire pressing groove 303 is used in conjunction with the primary coil pin 4 and the secondary coil pin 5 to achieve a better wire pressing effect. At the same time, the wire pressing groove 303 plays a role in passing the wire.

[0027] like Figure 1-5As shown, the primary winding coil frame 2 is an integrated structure consisting of a primary coil partition 202 and a primary coil cylinder 201. The primary coil partition 202 is symmetrically arranged at the front and rear ends of the primary coil cylinder 201. A boss 203 is provided at the upper end of the primary coil partition 202. Furthermore, the primary coil pin 4 of the primary winding coil frame 2 is provided on the surface of the boss 203. The boss 203 plays a positioning role, which makes the positioning more reliable and enables the operator to identify the installation direction; further, the joint of the boss 203 and the primary coil partition 202 is symmetrically provided with an inlet and outlet groove 204, which makes the inlet and outlet of the winding more convenient and prevents the winding from being worn by the edges.

[0028] like Figure 1-5 As shown, the first hollow structure 205 and the second hollow structure 301 are square structures, and the protrusion 101 is a square structure and is compatible with the first hollow structure 205 and the second hollow structure 301. The square structure has a better installation and positioning effect, and the secondary winding coil frame 3 can rotate clockwise and counterclockwise relative to the magnetic core 1, and the installation direction can be changed, so that the electrostatic high-voltage transformer has a wider range of applications.

[0029] like Figure 1-5 As shown, the secondary winding coil frame 3 is provided with a plurality of secondary coil partitions 6, and the secondary coil partitions 6 are provided with wire passing slots 601. The secondary coil partitions 6 are linearly and evenly arranged and extend to both ends of the secondary winding coil frame 3. Since the secondary winding coil frame 3 is a high-voltage output end and has a large number of coils, a plurality of secondary coil partitions 6 can prevent the coils from being broken down by high voltage, and the wire passing slots 601 are provided to facilitate wire passing and improve production efficiency.

[0030] like Figure 1-5 As shown, the upper and lower end faces of the secondary winding coil frame 3 are provided with output wire holes 302. The output wire holes 302 are reserved here to facilitate wire connection and can be applied to more working scenarios.

[0031] like Figure 1-5 As shown, the structures of the primary coil pin 4 and the secondary coil pin 5 are cylindrical or square, and the cylindrical structure is helpful for winding and has a better wire pressing effect. Furthermore, the cylindrical effect is better and the winding is not easily damaged.

[0032] Example 1

[0033] See Figure 4A primary coil pin 4 is provided on each of the four corners of the boss 203 of the primary winding coil skeleton 2. The primary coil pin 4 has a symmetrical structure. The protrusions 101 on both sides of the magnetic core 1 are inserted into the first hollow structure 205 of the primary winding coil skeleton 2 and the second hollow structure 301 of the secondary winding coil 3. The protrusions 101, the first hollow structure 205 and the second hollow structure 301 are square. At this time, the plane where the primary coil pin 4 is located is parallel to the plane where the secondary coil pin 5 is located.

[0034] Example 2

[0035] See Figure 5 A primary coil pin 4 is provided on each of the four corners of the boss 203 of the primary winding coil skeleton 2. The primary coil pin 4 has a symmetrical structure. The protrusions 101 on both sides of the magnetic core 1 are inserted into the first hollow structure 205 of the primary winding coil skeleton 2 and the second hollow structure 301 of the secondary winding coil 3. The protrusions 101, the first hollow structure 205 and the second hollow structure 301 are square. At this time, the plane where the primary coil pin 4 is located is perpendicular to the plane where the secondary coil pin 5 is located.

[0036] The above embodiments are merely descriptions for the purpose of clearly illustrating the present invention, and are not limitations on the implementation methods. Those skilled in the art may make other different forms of changes or modifications based on the above descriptions. It is not necessary and impossible to enumerate all implementation methods here, and the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
