Description
Technical field
The utility model relates to high-voltage electrical appliances field, specially a kind of solid insulation seat disconnecting switch.
Background technique
Traditional solid insulation isolating switch include isolation moving contact, grounding static contact and be electrically connected with main bus-bar every
From static contact, moving contact is isolated and is optionally contacted with grounding contact and isolation static contact, so that disconnecting switch is being closed a floodgate
Switch between position, isolated location and earthing position；Since seal body interior component is more, space is limited, this side
Formula undoubtedly increases the volume inside device noumenon, while increasing installation difficulty, and is not easy to operate, more arduously.
Utility model content
The purpose of the utility model is to provide a kind of solid insulation seat disconnecting switch, can effectively solve in background technique
Problem.
Realizing the technical solution of above-mentioned purpose is: solid insulation seat disconnecting switch, including insulating base, pacifies on the insulating base
Equipped with bus conductive rod, inlet-outlet line conducting rod, ground connection fixing seat, it is provided in the insulating base and is connect with what ground connection fixing seat was connect
Ground static contact, the inlet wire static contact being electrically connected with bus conductive rod, the inlet-outlet line static contact being electrically connected with inlet-outlet line conducting rod,
Be characterized in that: middle part is rotatably equipped with the isolation switch of V-arrangement in the insulating base, and the both ends of isolation switch are connected separately with dynamic touching
Head can make the moving contact at isolation switch both ends and grounding static contact, inlet wire static contact, inlet-outlet line quiet by rotating isolation switch
Any two of contact contact conducting.
Further, the outlet static contact is connect by arc-control device with inlet-outlet line conducting rod.
Further, the arc-control device includes vacuum interrupter and the insulated pull rod with vacuum interrupter cooperation, institute
Inlet-outlet line conducting rod is stated to be electrically connected with the static contact of vacuum interrupter, the moving contact of the vacuum interrupter by be flexible coupling with into
The electrical connection of outlet static contact.
Further, the whole body of the isolation switch is provided with enhancing nylon package, improves the insulating properties of isolation switch
Can, increase electrical strength.
When utility model works, when the moving contact at isolation switch both ends turn to respectively with inlet wire static contact, inlet-outlet line
When static contact contact conducting, closing function is realized；When the moving contact at isolation switch both ends turn to respectively with inlet-outlet line static contact
When being connected with grounding static contact, it is grounded function；It is not led with any static contact when the moving contact at isolation switch both ends turns to
When logical, isolation features are realized.
The isolation switch of the utility model isolated location when, realize double-fracture, safety is far longer than the prior art
In single break.
The utility model uses the isolation switch of V-arrangement, reduces the volume inside device noumenon, and work, which reduces, to be configured to
This, improves economic benefit.
Detailed description of the invention

Rotation isolation switch 8 can make the moving contact 9 and grounding static contact 5, inlet wire static contact 6, inlet-outlet line stationary contact at 8 both ends of isolation switch
First 7 any two contact conducting.
The arc-control device 10 being mounted in insulating base 1, interrupter cartridge are provided between outlet static contact and inlet-outlet line conducting rod
Setting 10 includes that vacuum interrupter 11 and the insulated pull rod 12 with the cooperation of vacuum interrupter 11, inlet-outlet line conducting rod 3 go out with vacuum
The static contact of arc chamber 11 is electrically connected, and the moving contact of vacuum interrupter 11 13 is electrically connected by being flexible coupling with inlet-outlet line static contact 7；Its
Middle vacuum interrupter 11 and insulated pull rod 12 are using conventional products in the prior art.
As shown in Figure 1, when 8 both ends of isolation switch moving contact 9 turn to respectively with inlet-outlet line static contact 7 and ground connection stationary contact
When first 5 conducting, it is grounded function；As shown in Fig. 2, when 8 both ends of isolation switch moving contact 9 turn to not with any static contact
When conducting, isolation features are realized；As shown in figure 3, when 8 both ends of isolation switch moving contact 9 turn to respectively with inlet wire static contact
6, when the contact of inlet-outlet line static contact 7 conducting, closing function is realized.
