Description

Dry-type transformer anti-vibration structure

Technical Field

The utility model relates to a transformer technical field, concretely relates to dry-type transformer antivibration structure.

Background

The transformer is a device for changing alternating voltage by utilizing the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core, and the transformer has the main functions of: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, and the like. There are various types of transformers, among which a dry type transformer refers to a transformer in which an iron core and a winding are not immersed in insulating oil, and the dry type transformer vibrates during operation, and thus a vibration damping device is generally disposed under the transformer. When vibration damper used for a long time, damping spring became invalid easily, influenced the damping effect, but unable audio-visual judgement vibration damper effect among the prior art, need unpack vibration damper apart usually and inspect, and the operation is comparatively troublesome.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide a dry-type transformer vibration-proof structure that can visually judge whether a damping spring has failed.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a dry-type transformer anti-vibration structure is characterized in that: close the casing on the bottom plate including bottom plate and lid, be provided with damping spring on the bottom plate, the last backup pad that is provided with of damping spring, be provided with the support column in the backup pad, be provided with the guiding hole that can supply the support column to stretch out on the casing, be provided with alarm device on the bottom plate, alarm device is including setting up two conducting strips, switch board, power and the alarm on the bottom plate, and one of them conducting strip links to each other with the power and another conducting strip connection alarm, the switch board sets up in the conducting strip top, the switch board downside is provided with the busbar that can make two conducting strips electricity connect, the switch board both ends are provided with reset spring, both ends link to each other with backup pad and bottom plate respectively about.

Further, the alarm is an LED lamp.

Furthermore, the four damping springs are distributed at four corners of the bottom plate, and the supporting plate is integrated and placed on the four damping springs.

Further, the upper side of the switch board is provided with a convex block protruding upwards.

Furthermore, the periphery of the spring wire of the return spring is coated with an insulating layer.

Furthermore, the conducting strips are provided with four groups and are arranged at the outer sides of the corresponding damping springs.

Compared with the prior art, the utility model has the advantages of it is following: after the damping spring of this antivibration structure became invalid, the corresponding position of backup pad can the downward sloping removal to oppression switch board moves down and communicates two conducting strips, and the alarm can move this moment and send alarm signal, reminds maintainer damping spring to become invalid, in time maintains the change.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

Fig. 1 is a schematic structural view of a preferred embodiment of the present application, and as shown in the drawing, the vibration-proof structure of the dry-type transformer includes a bottom plate 1 and a housing 2 covering the bottom plate 1, a damping spring 3 is disposed on the bottom plate 1, a supporting plate 4 is disposed on the damping spring 3, a supporting post 6 is disposed on the supporting plate 4, the dry-type transformer is placed on the supporting post 6, a guiding hole 21 for the supporting post 6 to extend out is disposed on the housing 2, an alarm device is disposed on the bottom plate 1, the alarm device includes two conductive sheets 51 disposed on the bottom plate 1, a switch board 52, a power supply (not shown in the drawing) and an alarm 53, one of the conductive sheets 51 is connected to the power supply, the other conductive sheet 51 is connected to the alarm 53, the switch board 52 is disposed above the conductive sheets 51, a conductive bar 54 for electrically connecting the, and two ends of the switch board 52 are provided with return springs 55, and the upper ends and the lower ends of the return springs 55 are respectively connected with the support plate 4 and the bottom plate 1.

In this embodiment, the alarm 53 is an LED lamp. Of course, the alarm can be given by means of a prompt tone and the like.

In the present embodiment, the damping springs 3 have four and are distributed at four corners of the base plate 1, and the support plate 4 is an integral body and is placed on the four damping springs 3. This is advantageous for improving the stability of the support plate 4 and reducing the shaking.
