(Splitting/combining) upgrading connector used in new round of rural power grid upgrading project

Abstract

The invention discloses a (splitting / combining) upgrading connector used in a new round of a rural power grid upgrading project. A square concave pit is formed in the bottom of the back surface of a double-groove T connector base body and a single-groove connector base body is arranged inside the square concave pit, so that the (splitting / combining) upgrading connector is characterized in that during maintaining and mounting operations on a 10 KV trunk line and a 0.4 KV trunk line, when equipment is not matched with the connector and the connector is not required to be correspondingly replaced according to an original design plan, through the square concave pit in the bottom of the back surface of the double-groove T connector base body, the double-groove T connector base body can be split from the single-groove connector base body inside the own concave pit. When the double-groove T connector base body is split from the single-groove connector base body, the double-groove T connector base body can be used as a parallel groove clamp and the single-groove connector base body can be used as an equipment clamp. When the single-groove connector base body and the double-groove T connector base body are combined again, a combination can be used as a T connector wire clamp again.

Description

technical field [0001] The invention relates to live work, and directly relates to (divided, grouped) upgrade adapters used in a new round of rural power network transformation and upgrading projects, and is especially suitable for use in high-voltage distribution line projects and live operation vehicles. Background technique [0002] In high-voltage distribution line engineering, fuses, lightning arresters, isolating switches, load switches, distribution transformers, transformers, and wall bushings are generally used to connect the crimping ends of the original and existing parallel trench clamps and equipment. Clamp, T terminal clamp to complete the connection. When fuses, lightning arresters, isolating switches, load switches, distribution transformers, transformers, wall bushings, and parallel trench clamps, equipment clamps, and T clamps on equipment are naturally damaged or have sudden failures during operation When maintenance or replacement is required, maintenanc...

AI Technical Summary

Problems solved by technology

[0003] In the event of a sudden failure, it is very easy to appear when the power is turned off: 1. Since there are many users on the main power supply line of the power system, when a household's electrical equipment has a safety hazard or a sudden failure, it needs to be replaced or maintained in time When the main line is used decisively and suddenly, it will easily cause heavy economic losses to the users of the whole line.

2. What is more important is: when a household’s electrical equipment has potential safety hazards or sudden failures that need to be replaced or maintained in time, the main line will be decisively cut off suddenly, and it will be connected to the Class A users on the same line And users involved in certain special industries are prone to major economic losses and unforeseen unsafe major accidents after sudden power outages

The main reasons for the extremely inconvenient operation of the original equipment clamp are: 1. The original equipment clamp is also a split structure, and there are also small bolts and nuts that are also difficult to be pinched by fingers wearing thick insulating gloves.

2. That is to say, the end of the wire has been firmly pressed into the equipment clamp, and the crimping plate of the equipment clamp must be pressed firmly on the plate body of the equipment crimping plate again. When the crimping plate of the equipment clamp is connected to the equipment When crimping the crimping plate, it is necessary to unscrew the bolt rod and nut on the crimping plate of the equipment. This is a difficult problem that restricts the operator from unscrewing and screwing in the bolt rod and nut. three

[0011] When the initial end (i.e. the power supply end) of the newly added line is installed in the insulating arm bucket under the live main line, when the iron load and equipment are installed in the insulating arm bucket under the live main line, the iron load and equipment are completed. After installation, the T-connection line on the iron pole equipment must also be connected to the T-point of the live main line with the same original parallel ditch clamp, which is also very prone to other unforeseen and unsafe major accidents. Occurred technical problems four
