First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The structure of the super high voltage transformer including the safety raiding means according to the embodiment of the present invention is as follows.

That is, the present invention is characterized in that it comprises an attachment plate 121 attached to the upper side of a side surface of the superhigh-voltage transformer 110, a bracket 122 formed on the attachment plate 121, The ladder 130 is formed between the ladder 130 and the attachment plate 121 and has a resilient force to allow the ladder 130 to be lifted from the floor. When a load equal to or greater than the elasticity of the spring 124 is applied to the ladder 130 while the super-high voltage transformer 110 is in a live state and is located between the attachment plate 121 and the ladder 130, A switch 125 for driving the alarm device 150 and a controller 140 for controlling the switch 125 and the alarm device 150. The switch 125 and the touch sensor 132, And a power supply unit 160 for supplying power to the control unit 140, the alarm device 150, and the like.

The weight of the spring 124 is greater than the elasticity of the spring 124. This means that the worker has climbed onto the ladder 130 to climb above the ultra-high voltage transformer 110, The weight of the ladder 130 is such that the lower end of the ladder 130 touches the ground by overcoming the elasticity of the spring 124. [ It is natural that the manufacturer can arbitrarily adjust it in consideration of the work situation.

The switch 125 may be a micro switch and a contact switch 125 that are inexpensive and stable in operation and may be any device capable of sensing the movement of the ladder 130 and sending a signal to the controller 140 It is also acceptable.

The alarm device 150 may include a warning light and a speaker (siren), and may be any means capable of informing the operator that the device is in a live state and is in a dangerous condition.

In addition, the present invention can also be configured to include safety means in order to ensure safety of the operator. To accomplish this, in order to ascend the super-high voltage transformer 110, the first and second scaffolds of the ladder 130, And the touch sensor 132 may be mounted on the upper surface.

Accordingly, when the operator elevates the foot of the ladder 130 in the active state of the superhigh-voltage transformer 110, the alarm device 150 is driven under the control of the controller 140.

As described above, according to the present invention, when the operator intends to climb over the super-high voltage transformer 110 for in-service repair and inspection in the live state of the super-high voltage transformer 110, the worker's work intention is confirmed by the weight applied to the ladder 130 Thereby alerting the user to the alarm, or when the ladder 130 is raised at the same time, an alarm is sounded so that the operator can be doubly protected.

The control unit 140 includes a memory and various modules programmed therein so that the alarm device 150 can be driven by the signals of the switches 125 and the touch sensor 132. [

The power supply unit 160 may include a solar battery panel and a rechargeable battery.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
