Detachable busbar for gas insulated switchgear (GIS)

Abstract

The invention discloses a detachable busbar for a GIS. The busbar comprises a drum portion, conducting rods, a fixed conductor assembly, wherein the drum portion comprises a plurality of cases which are serially arranged at intervals, a flexible connecting drum is detachably connected between two adjacent cases, each case is provided with a hand hole detachably connected with a hand hole cover, the conducing rods are connected in the drum portion, the ends of the conducting rods are connected with the fixed conductor assembly, and the position of the fixed conductor assembly corresponds to the position of the hand hole. The fixed conductor assembly comprises two conductor contact seats and a fixed conductor, wherein the two conductor contact seats are detachably connected with adjacent ends of two adjacent conducting rods respectively, the fixed conductor is provided with a U-shaped opening seat which is provided with a U-shaped opening and arranged between the two conductor contact seats, a fastener is arranged at the U-shaped opening, and the conductor contact seats and the U-shaped seat can be detachably connected through the fastener. The busbar has the advantages of being capable of maintaining the through-current capacity of conductors and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of switchgear, in particular to a detachable busbar used in GIS equipment. Background technique [0002] With the rapid development of the industrial field, the scale of the power grid is becoming larger and larger, and the voltage level is also increasing. The gas-insulated metal-enclosed switchgear has the advantages of being less affected by the external environment, saving land, and does not require frequent maintenance. Therefore, in substations It is used more and more widely. [0003] In the actual application of substations, when the GIS equipment fails and needs to be repaired, in order to shorten the power outage time or maintenance workload, it is often necessary to remove the equipment in the faulty section. . Restricted by the connection mode of the shell and the coaxial plug-in electrical connection mode of the internal conductor, the direct removal method of the intermediate fault segment becomes unfe...

Problems solved by technology

It has the following disadvantages: 1. The demolition workload is large and time-consuming; 2. The demolition may cause equipment damage

Although it can achieve the advantage of "directly removing the shell of the faulty section and the internal connecting conductor without removing the connecting bus bars or equipment at both ends", it also has the following disadvantages: 1. The electric field of the dumbbell-shaped removable conductor is uniform Poor performance, which will form a bottleneck in the flow capacity of the conductor; 2. The structure is complex; 3. It is inconvenient to disassemble
