Description

Technical Field

[0001] The utility model relates to the technical field of reactor equipment, in particular to a resin-insulated dry-type iron core starting reactor. Background Art

[0002] The clamping of the reactor core has a great impact on the reactor. The parallel reactor will generate a certain amplitude of vibration during the startup and operation process. If this vibration is not avoided and controlled, it is easy to cause the loosening of the structural parts, making the insulation resistance of the core clamp too low, causing equipment accidents. Due to the magnetic leakage of the core, the reactor cannot clamp the core laminations in the center. Therefore, it is necessary to clamp the core outside the core laminations to reduce the noise of the core and reduce the vibration of the reactor. However, in the prior art, such as the prior art with patent number: CN212782954U, the structure of the core clamping device is relatively complex. Although it has good stability, it is not conducive to disassembly and maintenance. Utility Model Content

[0003] The utility model aims to provide a resin-insulated dry-type iron core starting reactor to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a resin-insulated dry-type iron core starting reactor, comprising an upper clamp and a lower clamp, and an iron core, a coil arranged on the iron core, and a connecting terminal arranged on the coil are arranged between the upper clamp and the lower clamp; the upper clamp and the lower clamp both comprise a first clamp and a second clamp; wedge-shaped grooves are arranged on the facing surfaces of the first clamp and the second clamp, and wedge blocks are arranged in the wedge-shaped grooves; the upper clamp is connected to the first clamp and the second clamp by a provided pressure plate to press the wedge blocks into the wedge-shaped grooves to achieve the upper end of the iron core being compressed; the upper clamp is connected to the first clamp and the second clamp on the lower clamp by a provided support member to prompt the wedge blocks to compress the iron core from the lower end.

[0005] As a preferred technical solution of the utility model: the support member includes a support plate and a support pad slidably installed in the support plate.

[0006] As a preferred technical solution of the utility model: the wiring terminal is connected to a provided binding post, and the binding post is rotated inside the wiring terminal to adjust the installation angle of the wire.

[0007] As a preferred technical solution of the utility model: the wiring terminal is also provided with a fastener, which is connected to the wiring terminal through the fastener to fix the wiring post on the wiring terminal.

[0008] As a preferred technical solution of the utility model: a boss is provided at one end of the terminal post, and a rubber ring is also sleeved on the terminal post.

[0009] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: when one end of the pressure plate is connected to the first clamping plate on the upper clamping piece, and the other end is connected to the second clamping plate on the upper clamping piece, as the pressure plate moves downward, the wedge block is prompted to squeeze the iron core from both sides of the iron core at the same time during the downward movement, so that the silicon steel sheets constituting the iron core can be reliably fitted together, thereby reducing the phenomenon of abnormal noise in the reactor caused by the large gap between the silicon steel sheets; similarly, by connecting the support member with the first clamping plate and the second clamping plate on the lower clamping piece, the wedge block on the lower clamping piece can be prompted to squeeze the iron core, thereby ensuring that both the upper and lower ends of the iron core have reliable clamping force, thereby reducing abnormal phenomena that occur when the iron core is working.

DETAILED DESCRIPTION

[0015] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0016] See also Figure 1-4 The utility model provides an embodiment: a resin insulated dry-type iron core starting reactor, comprising an upper clamp 1 and a lower clamp 4, wherein an iron core 5, a coil 2 arranged on the iron core 5, and a connection terminal 9 arranged on the coil 2 are arranged between the upper clamp 1 and the lower clamp 4; the upper clamp 1 and the lower clamp 4 both comprise a first clamping plate 11 and a second clamping plate 15; the first clamping plate 11 and the second clamping plate 15 are both provided with a wedge-shaped groove 12 on the facing surfaces thereof, and a wedge block 13 is provided in the wedge-shaped groove 12; the upper clamp 1 is connected with the first clamping plate 11 and the second clamping plate 15 by a provided pressing plate 14, so as to press the wedge block 13 into the wedge-shaped groove 12, so as to achieve the upper end of the iron core 5 being pressed; the support member 3 is provided to connect with the first clamping plate 11 and the second clamping plate 15 on the lower clamp 4, so as to prompt the wedge block 13 to press the iron core 5 from the lower end thereof.

[0017] Based on this, the wedge block is used to press the iron core 5 so that the silicon steel sheets constituting the iron core can be reliably fitted together to reduce the abnormal noise of the reactor caused by the large gap between the silicon steel sheets; similarly, the upper clamp 1 and the lower clamp 4 can be used to clamp the upper and lower sides of the iron core 5 at the same time, so that both the upper and lower ends of the iron core 5 have reliable clamping force to reduce abnormal phenomena when the iron core 5 is working. In addition, the cooperation between the wedge block 13 and the wedge-shaped groove 12 can simply and conveniently realize the clamping of the iron core 5, thereby simplifying the structure of the clamping and fixing device of the iron core 5.

[0018] Furthermore, since the support member 3 includes a support plate 30 and a support pad 31 slidably installed in the support plate 30, the support pad 31 can be used to absorb vibrations during operation of the device to reduce noise during use of the device; wherein the support pad 31 is preferably made of rubber.

[0019] In the prior art, the wire is directly installed on the coil 2. This installation method has the following problems: once the wire and the coil 2 become loose, the coil 2 will be burned. In addition, the fastening equipment such as bolts directly acts on the coil 2, which can easily cause damage to the coil 2. When the coil 2 is damaged, it needs to be replaced as a whole, which will increase the maintenance cost of the equipment.

[0020] To this end, the terminal 9 is connected to a terminal post 10, and the terminal post 10 is rotated inside the terminal 9 to adjust the installation angle of the wire. Therefore, by rotating the terminal post 10, wires of different angles can be installed on the terminal post 10. In particular, the terminal post 10 is connected to the wire to avoid direct connection of the wire to the terminal 9, so as to extend the service life of the terminal 9 and thus extend the service life of the coil 2.

[0021] Furthermore, since a fastener 8 is also provided on the wiring terminal 9, the fastener 8 is connected to the wiring terminal 9 to fix the terminal 10 on the wiring terminal 9. Therefore, when the wire is connected, the fastener 8 can be tightened to fix the terminal 10 on the wiring terminal 9 to prevent the terminal 10 from rotating freely.

[0022] Furthermore, since a boss 6 is provided at one end of the terminal post 10, and a rubber ring 7 is also mounted on the terminal post 10, when the fastener 8 fixes the terminal post 10 to the terminal 9, the rubber ring 7 can be squeezed to deform the rubber ring 7 to fill the gap between the terminal post 10 and the fastener 8 and between the fastener 8 and the terminal 9; thereby, the phenomenon of rust on the terminal 9 caused by rainwater infiltration when the device is used can be reduced. The fastener 8 is preferably a nut, and the terminal 9 is preferably an external threaded column.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
