A safety knife for power distribution

Abstract

The invention belongs to the field of power distribution auxiliary devices, in particular to a safety knife for power distribution. By changing the structure of the existing knife, eliminating passageways on the existing knife, the whole internal structure of the knife is sealed and protected, External substances are difficult to enter into the knife, At that same time, the conductive structure onthe original knife is isolate from the operation handle, the conductive structure is inside the knife in the operation process, and the external operation structure is always in an insulated state, so that the safety and the usability of the knife are improved, the grip position needs no consideration in the use or the handling process, and the efficiency of each work is improved.

Description

Technical field [0001] The invention belongs to the field of power distribution supporting devices, and particularly relates to a safety switch for power distribution. Background technique [0002] With the development of distribution network technology, the supporting equipment of the distribution network is constantly updated. As the basic node control device in the distribution network, the knife is indispensable in simple line connection or complex regional grid control. Although many types of electromagnetic and electronic knives suitable for different environments have been derived from the distribution network, they can directly replace traditional open and close knives in many occasions to achieve different purposes. However, the cost of production and the difficulty of manufacturing In terms of durability and ease of operation, the traditional open-close type knife still has a certain application market.

Problems solved by technology

[0002] With the development of distribution network technology, the supporting equipment of the distribution network is also constantly updated. As the basic node control device in the distribution network, the switch knife is indispensable no matter in simple line connection or complex regional power grid control. Although there are many kinds of electromagnetic and electronic switch blades suitable for different environments in the distribution network, they can directly replace the traditional open and close switch blades in many occasions to achieve different purposes, but from the perspective of production cost and manufacturing difficulty In terms of durability and ease of operation, the traditional open-close type switch knife still has a certain application market. The traditional switch knife has a simple structure, is not easy to be damaged, and is easy to operate, and can adapt to various complex on-site environments. Insufficient, for example, because the existing switch knife needs to open and close the blade up and down to realize the state transition of the circuit, it is necessary to dig a channel for the blade to move on the outer casing. Connected with the external environment, the channel can pass through various substances such as iron wire, raindrops, and soil. When the knife is used in the open environment or often needs to be transported and transferred, for example, it is used for mobile operations, such as road construction, construction, pipeline construction, etc. , all kinds of substances can easily enter the inside of the switch knife from the channel, and at the same time, the lower end of the common operating handle of the switch knife is provided with a metal sheet connected to the switch blade. During the closing process of the switch knife, the metal sheet structure is in a charged state for a period of time. If you accidentally touch it during the process, you will get an electric shock
