Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to an early warning mechanism and a transformer protection device. Background Art
[0002] The transformer will vibrate during daily use. Among them, the core vibration caused by magnetostriction and the core vibration caused by leakage magnetic flux at the joints of silicon steel sheets and between laminations are normal vibrations during normal operation and are unavoidable.
[0003] However, when there are some problems or abnormal conditions in the transformer, its vibration may increase. For example, the insulation material inside the transformer is aging, the winding is loose or broken, or the core connection is loose; or the insulation failure causes breakdown or discharge between the internal components of the transformer, resulting in increased vibration; or the electrical overload, short circuit or grounding fault inside the transformer causes abnormal changes in the current and magnetic field inside the transformer, which in turn causes mechanical vibration; especially when the core steel sheet in the transformer winding is loose, it will produce large lateral vibration. Excessive vibration of the transformer indicates that it may be damaged inside and may also cause harm to nearby people.
[0004] However, a large portion of the transformers currently in use are in the wild or at high places, making it inconvenient to observe their vibration conditions on a daily basis. Therefore, a transformer vibration warning is needed to remind nearby pedestrians to pay attention to safety. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0030] Example 1, reference Figure 1 to Figure 3, which is the first embodiment of the utility model. This embodiment provides an early warning mechanism, which can monitor the vibration of the transformer. When the transformer vibrates abnormally, an alarm is sounded to remind nearby pedestrians to stay away from risks. It includes a knocking component 100, including a shell 101, a transmission component 102 arranged inside the shell 101 and in contact with the transformer, a knocking component 103 arranged on the top of the transmission component 102, and a sound component 104 arranged on the side of the knocking component 103. When the transformer vibrates with an abnormally large amplitude, the transmission component 102 will drive the knocking component 103 to knock on the sound component 104 to make noise, reminding the maintenance personnel. The light-emitting element 105 is arranged on the side of the outer wall of the shell 101. When the knocking component 103 knocks on the sound component 104, the light-emitting element 105 will flash to enhance the reminder effect.
[0031] Furthermore, the housing 101 includes a shell 101a, and a slide groove 101b is provided inside the shell 101a. The slide groove 101b includes a square groove with a long square hole for the transmission component 102 to slide, and a receiving groove is also provided at the bottom of the square groove.
[0032] Furthermore, the transmission component 102 includes a rack 102a inside the shell 101a, a limit plate 102b is arranged at the bottom of the rack 102a, and an elastic member 102c is arranged on the side of the limit plate 102b. The elastic member 102c and the limit plate 102b are arranged inside the accommodating groove, and the elastic member 102c is in a compressed state. A transmission plate 102d is arranged on the side of the rack 102a, and the elastic member 102c will apply a force toward the transmission plate 102d to the limit plate 102b, and the limit plate 102b limits the farthest sliding stroke of the rack 102a toward the limit plate 102b. The transmission plate 102d contacts the outer wall of the transformer. When the transformer vibrates, it will drive the transmission plate 102d and the rack 102a to slide, and the rack 102a and the transmission plate 102d will reset under the action of the elastic member 102c to slide back and forth following the vibration of the transformer.
[0033] Furthermore, the striking assembly 103 includes a gear 103a arranged inside the shell 101a, and a metal ball 103b is arranged on the side of the gear 103a. The rack 102a slides back and forth under the influence of the vibration of the transformer and drives the gear 103a to rotate. The rotation of the gear 103a drives the metal ball 103b connected thereto to swing back and forth. When the transformer has an abnormal vibration with an excessive amplitude, the sliding amplitude of the rack 102a will increase accordingly, and the swing amplitude of the metal ball 103b will increase as the amplitude of the rotation of the gear 103a increases.
[0034] Preferably, the bottom of the gear 103a is meshed with the rack 102a, a slide 101c is provided on the top of the housing 101a, and the sound generating assembly 104 includes a slide rod 104a provided inside the slide rod 101c, the cross section of the slide rod 104a is the same as the slot on the top of the slide rod 101c, the slide rod 104a can slide in the slide rod 101c, copper tubes 104b are provided on the top of both ends of the slide rod 104a, a rotating rod 104c is provided on the bottom of the copper tube 104b, the top of the rotating rod 104c is connected to the copper tube 104b through a sleeve ring, the copper tube 104b can rotate in the sleeve ring, and the rotating rod 104 c is provided with a rotating wheel 104d at the bottom, and the side of the rotating wheel 104d is connected to the shell body 101a, and the rotating wheel 104d is threadedly connected to the outer wall of the shell body 101a. Rotating the rotating wheel 104d will drive the rotating rod 104c to rotate, and drive the copper tube 104b and the sliding rod 104a to slide on the sliding rack 101c to adjust the position of the copper tube 104b and change the relative distance between the copper tube 104b and the knocking ball. During installation, the distance between the copper tube 104b and the knocking ball is adjusted to ensure that the vibration of the transformer drives the knocking metal ball 103b to shake and there is a gap between it and the copper tube 104b, and no contact occurs.
[0035] Usage process: During installation, adjust the distance between the copper tube 104b and the knocking ball to ensure that the vibration of the transformer drives the knocking metal ball 103b to shake and there is a gap between it and the copper tube 104b, and no contact occurs. When the transformer has an abnormal vibration with an amplitude that is too large, the sliding amplitude of the rack 102a will increase accordingly, and the metal ball 103b will increase with the increase in the amplitude of the rotation of the gear 103a. The shaking amplitude of the metal ball 103b will increase, and the metal ball 103b will knock on the copper tube 104b to make noise, reminding nearby pedestrians that the transformer has an abnormal vibration.
[0036] Example 2, reference Figure 1 to Figure 4 , which is the second embodiment of the present utility model, is different from the previous embodiment in that a power source 106 is provided on the side of the outer wall of the shell 101a.
[0037] Preferably, the positive pole of the power supply 106 is electrically connected to the copper tube 104b, the negative pole of the power supply 106 is electrically connected to the light-emitting element 105, and the light-emitting element 105 is electrically connected to the metal ball 103b. When the transformer is in normal use, the distance between the copper tube 104b and the knocking ball ensures that there is a gap between the knocking metal ball 103b and the copper tube 104b when the vibration of the transformer drives the knocking metal ball 103b to shake, and no contact occurs. At this time, the circuit composed of the power supply 106, the light-emitting element 105, the metal ball 103b and the copper tube 104b is in a cut-off state. At this time, the light-emitting element 105 and the signal generator 106 are not working. When the transformer vibrates abnormally with an amplitude that is too large, the sliding amplitude of the rack 102a will increase accordingly, and the shaking amplitude of the metal ball 103b will increase as the amplitude of the rotation of the gear 103a increases.
[0038] Usage process: When the transformer vibrates abnormally with an amplitude that is too large, the sliding amplitude of the rack 102a will increase accordingly, and the shaking amplitude of the metal ball 103b will increase as the amplitude of the gear 103a rotates. The metal ball 103b will continuously hit the copper tube 104b, and the circuit composed of the power supply 106, the light-emitting element 105, the metal ball 103b and the copper tube 104b will be intermittently connected, so the light-emitting element 105 will flash, reminding the surrounding personnel that the transformer has vibrated abnormally.
[0039] Example 3, reference Figure 1 to Figure 5 , which is the third embodiment of the utility model, and further provides a transformer protection device. It includes an early warning mechanism; and, an installation component 200, including a base 201, the material of the base 201 is wood, a bracket 202 is arranged on the top of the base 201, and the top of the bracket 202 is fixedly connected to the housing 101.
[0040] Preferably, arc-shaped connecting rods 203 are provided at both ends of the top of the base 201, and a rain shield 204 is provided on the top of the arc-shaped connecting rod 203. The wooden base 201 absorbs the vibration transmitted from the transformer mounting base to prevent the vibration from interfering with the normal operation of the early warning mechanism. At the same time, the rain shield 204 will protect the transformer and the early warning mechanism from rain.
[0041] Usage process: install the wooden bracket 202 on the bottom mounting frame of the transformer, the wooden base 201 will absorb the vibration transmitted from the transformer mounting frame to prevent the normal vibration of the transformer from affecting the work of the early warning mechanism, and the rain shield 204 will protect the transformer and the early warning mechanism from rain.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.
[0043] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
