Embodiment 1

[0030] The present invention provides a retractable arc extinguishing component switching device, which includes a turntable 6 and a turntable shaft 2 arranged on the turntable 6, and several arc extinguishing component storage slots 5 for placing arc extinguishing components 7 are evenly distributed on the edge of the turntable 6, The arc extinguishing assembly 7 is arranged in the storage groove 5 of the arc extinguishing assembly. The rear end of the turntable 6 is provided with a bottom plate 3 , an elastic assembly 4 is provided between the arc extinguishing assembly 7 and the bottom plate 3 , and the elastic contact between the elastic assembly 4 and the arc extinguishing assembly 7 is arranged. A casing frame 1 is sheathed on the outside of the turntable 6, and the casing frame 1 is slidably arranged in contact with the front end of the turntable 6, and the arc extinguishing assembly 7 is pressed and arranged. An arc extinguishing cylinder 8 is arranged on the housing f...

Embodiment 2

[0036] The elastic component 4 is a spring or a shrapnel, one end is fixed on the base of the arc extinguishing component 7, the other end is fixed on the bottom plate 3, and is arranged in the storage groove 5 of the arc extinguishing component, and the bottom plate 3 is attached to the rear end of the turntable 6 Fixed setting. In addition to springs or elastic sheets, other parts or devices with elastic functions can be used. The elastic component 4 is mainly to elastically eject the arc extinguishing component 7, and the arc extinguishing component 7 is stuck in the arc extinguishing cylinder 8, and then when the elastic component 4 is compressed and the turntable 6 is rotated, the arc extinguishing component 7 is released to realize The locking position of the next arc extinguishing component 7 realizes switching.

Embodiment 3

[0038] It also includes an induction coil 9 and a wire 10. There are two trigger signal input terminals on the base of the arc extinguishing component 7, and the two trigger signal input terminals are arranged in the elastic component 4; one of the trigger signal input terminals is connected to the base plate 3 through a wire 10, The other trigger signal input terminal is connected to the metal shell outside the arc extinguishing assembly 7 through a wire 10, and a metal electrode is provided in each arc extinguishing assembly storage slot 5 of the turntable 6, and the metal electrode is connected to one end of the induction coil 9 through a wire 10 , the other end of the induction coil 9 is connected to the base plate 3 . The induction coil 9 is used to induce current, and then transmits the induced current to the arc extinguishing assembly 7 to detonate, and then the fuel in the arc extinguishing assembly 7 burns to realize jetting, which is very good for triggering arc extin...

Abstract

The invention discloses a telescopic arc extinguishing assembly switching device, which belongs to the field of arc extinguishing switching devices, and comprises a turntable and a turntable rotatingshaft arranged on the turntable, a plurality of arc extinguishing assembly storage grooves for placing arc extinguishing assemblies are uniformly distributed at the edge of the turntable, and the arcextinguishing assemblies are arranged in the arc extinguishing assembly storage grooves. A bottom plate is arranged at the rear end of the turntable, an elastic assembly is arranged between the arc extinguishing assembly and the bottom plate, the elastic assembly and the arc extinguishing assembly are arranged in an elastic contact mode, and the turntable is sleeved with a shell frame. The switching effectiveness and reliability of the arc extinguishing assembly are improved, the problem of jamming during rotation of the arc extinguishing turntable is avoided, one end part of the arc extinguishing assembly at the triggering position extends into the arc extinguishing cylinder and has a relatively strong sealing effect on strong air flow generated during triggering, so that the strong air flow acts on an electric arc to the maximum extent, and the arc extinguishing capability is improved; and the arc extinguishing assembly stretches into the arc extinguishing assembly storage groove byusing the rear acting force of the jet flow.

Description

technical field [0001] The invention relates to the field of arc extinguishing switching devices, in particular to a retractable arc extinguishing component switching device. Background technique [0002] Lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are still one of the important factors affecting the safety of the power grid. Lightning strikes on transmission lines cause flashover of line insulators, and the resulting power frequency freewheeling damages insulator strings and fittings, resulting in burnt insulator strings and wire burnout accidents. [0003] Existing lightning protection devices for transmission lines mainly use transmission line lightning protection gap devices, but the key to lightning protection used in existing lightning protection gap devices is to use gas generators for arc extinguishing treatment. When the gas assembly is in the trigger positio...
