Abstract
The present invention relates to a protective cover for covering an entire insulator for preventing leakage of electric current at a wire connecting portion and contacting of foreign matter which may deteriorate insulation performance of the insulator in insulators such as a transformer or an arrester.
According to another aspect of the present invention, there is provided an electric power transmission system including a head portion surrounding the electric wire connection portion of the insulator, the insulator being connected to a transmission line, and a body portion surrounding the insulator body, And an opening is formed in the opening, and a sealing member for sealing the inside of the insulator protective cover is attached to the opening.
The insulator protection cover according to the present invention protects not only the wire connection part but also the body, so that the insulation function of the insulator can be maintained for a longer time. In addition, it has a temperature sensor capable of measuring the temperature of the insulator protection cover and informing the user of abnormality, so that it is possible to easily check the replacement time or abnormality of the insulator.
Description
The present invention relates to a protection cover for an insulator, and more particularly, to a protection cover for insulator such as a transformer or a lightning arrester, which covers the insulator to prevent contact between the insulator and the insulator, Cover.
Insulators are generally used for insulation of transformers, lightning arresters, etc.
3 is a view showing an example of an insulator.
Referring to FIG. 3, the insulator includes a body made of ceramic or silicon and a wire connection portion to which electric wires are connected. However, if the wire connection is exposed to the outside, foreign matter or rainwater may corrode the wire connection part and cause short-circuit.
In order to overcome such a problem, Utility Model Registration Nos. 20-0451085 and 0117122 and the like have been filed for a protective cover for protecting the wire connecting portion.
The above-mentioned conventional utility model is for protecting only the wire connecting portion of the insulator, and there is no protection function for the insulator body. However, the body made of ceramics or silicon actually suffers from insufficient insulation when subjected to long-term exposure to wind and dust, especially wind and dust, which have been exposed to salt in coastal areas. This means that you have to clean the insulators quarterly or semi-annually, which is a considerable effort and cost.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a protective cover that can cover an insulator body as well as a wire connection portion so that the insulator can be maintained for a long period of time .
The insulator protection cover for protecting the insulator provided in the transmission line includes a head portion surrounding the insulated wire connection portion of the insulator connected to the power transmission path and a body portion surrounding the insulator body, And a sealing member for sealing the inside of the insulator protection cover may be attached to the opening.
The head portion and the body portion are coupled by fitting, and a sealing member for sealing the inside of the insulator protection cover may be attached to a portion where the head portion and the body portion are coupled.
In addition, the insulator protection cover may further include a temperature sensor for measuring a temperature inside the insulator protection cover, and determining that the insulator is abnormal when the temperature is equal to or higher than a predetermined value to emit the light emitting element.
The insulator protection cover according to the present invention protects not only the wire connection part but also the body, so that the insulation function of the insulator can be maintained for a longer time.
In addition, it has a temperature sensor capable of measuring the temperature of the insulator protection cover and informing the user of abnormality, so that it is possible to easily check the replacement time or abnormality of the insulator.

In addition, by inserting a temperature sensor inside the insulator protection cover, the insulator abnormality can be detected by monitoring the internal temperature. The temperature sensor includes a light emitting element such as an LED, and if the internal temperature rises above a predetermined temperature, it is determined that there is an insulator, so that the light emitting element can emit light.
