Busbar connection device

Abstract

The invention relates to a bus coupling device, which comprises two bus insulators and a bus connector. A plurality of contacts are buckled with gaps which are mutually corresponding on two lining rings to form a hollow column; a plurality of spring rings and two gear rings are respectively hooped in two spring gaps and gear ring gaps of the hollow column; the hollow column, the spring rings and the two gear rings form a conductive body which is fixed inside an insulating sheath through teeth of the gear rings and an inner wall of the insulating sheath. When in use, two current-carrying busesare respectively connected with electrical contacts of the two bus insulators; the two ends of the bus connector are respectively buckled with the electrical contacts of the two bus insulators; the two current-carrying buses are connected together through one bus insulator, the bus connector and the other bus insulator. The bus coupling device has the advantages of easy installation, cabinet structure and no exposed conductive part and can be used for the connection between two close high-voltage high-current electric apparatuses, the power transmission is not easy to be influenced by the outside, and the safety and the stability for the power transmission can be ensured.

Description

technical field [0001] The invention relates to a busbar connection device, more precisely, a high-voltage, high-current busbar connection device, which belongs to the technical field of power distribution. Background technique [0002] In the power distribution technology of urban and rural power grids, it is a routine job to connect the current-carrying busbar of one electrical device with the current-carrying busbar of another electrical device. The potential and carrying capacity of these current-carrying buses are in the order of 10kV-25kV and 200A-600A, respectively. Background Art The technical solution to this technical problem is: the current-carrying busbars of the two electrical equipment are led out from the respective electrical equipment through the conductors of the respective insulating porcelain bottles, and then the conductors of the two insulating porcelain bottles are connected together by cables. Although this cable connection method is technically very...

Problems solved by technology

[0003] The technical level of the construction personnel is uneven, and the cable connection has certain technical requirements. The steps of the connection operation are complicated, and the connection between the electrical equipment and the electrical equipment is often unreliable due to human factors, resulting in unnecessary quality when the equipment is running. ACCIDENT

[0004] When using cable connection, the bending radius of the cable installation and the working space of the construction personnel must be considered. This requires that there must be a considerable distance between the electrical equipment, resulting in the structure of the connected electrical equipment being not compact and occupying a large space. Limits the scope of use of some electrical equipment

[0005] If the cable connection is used, the exposed cable head will appear, which is an important safety hazard affecting the normal operation of electrical equipment. If the protective measures are not in place, the exposed cable head will encounter water and debris, etc., which will cause equipment damage and even cause personal injury accidents.

If an insulating sleeve is used to insulate the exposed cable head from the outside world, first, the construction is difficult and the efficiency is low. Second, the reliability cannot be guaranteed. The connection part of the cable head has a high voltage. The cover is easy to loosen, lose the insulation effect, and even bury the hidden danger of failure
