Description
Technical field
The utility model is related to a kind of middle high-pressure switchgear technical field more particularly to a kind of three works of inflating switch cabinet
Position disconnecting switch and bus connecting device.
Background technology
Gas insulation switch cabinet is as arc extinguishing and dielectric using gas；Gas-filling cabinet uses air hermetic structure, switch
Cabinet is hermetically sealed, all insulation structure；Busbar, switch and charging member are completely enclosed in Stainless Steel Shell.Primary conductive system
It is completely independent in the running environment in gas medium, therefore not by extraneous environment（Such as：Condensation, filthy, salt fog, toy
And chemical substance etc.）Influence, be truly realized it is non-maintaining, suitable for various severe places, even if in poles such as water loggings in short-term
Also it can guarantee switch normal operation in the case of end.Also provided to the user reliable electricity system and economy operation and maintenance into
This.
Tri-station isolating switch, breaker, main bus-bar and branch bar, which constitute, in the design of inflating switch cabinet leads back
Road plays main function in switchgear.Three-phase pole is arranged along cabinet wide direction in existing inflating switch cabinet, smaller apart, absolutely
Edge distance is very narrow；The isolation end static contact fixed form of three-station is unstable, easily by the branch busbar being connect with main bus-bar
It involves, installation site is caused to be not allowed, the moving contact of three-station is inserted into difficulty.And add between connector one or several
The copper bar of bending will necessarily easily form hidden failures in installation and use, as shown in Figure 1 there are certain error in this way.
In existing inflating switch cabinet, tri-station isolating switch and bus connecting device, referring to Fig. 1, the main bus-bar 20 of three-phase is level one
Font alignment placement is needed by leading to switching branch bar 18 under main bus-bar branch bar 19；Switching branch bar 18 1
End is fixed on 14 poles, is connect above with main bus-bar branch bar 19, and static contact 17 is installed at intermediate position；Moving contact 16 is through touching
Head tube 15 and connection busbar 13 are installed on pole 14, and moving contact 17 connects screw 11, moving contact 17 is driven to move by screw 11, real
Existing three-station function；Another side is equipped with grounding static contact 12, and grounding static contact 12 connects earth bus.But in this way
Assembly method make static contact 17 by pole 14, main bus-bar branch bar 19, transfer branch bar 18 installation accuracy influenced,
Not only increase copper bar usage amount, increase cost, it is also difficult to ensure that assembling reaches precision and requirement.
Invention content
The purpose of this utility model is to provide a kind of tri-station isolating switch and bus connecting device, the attachment device
Motion stability is reliable when moving contact is inserted into static contact.
In order to realize above-mentioned technical purpose, the utility model adopts the following technical solution：
A kind of tri-station isolating switch and bus connecting device, including：Screw, pole, grounding static contact, insulating cylinder, company
Busbar, contact pipe, moving contact, static contact, main bus-bar are connect, the static contact is directly installed on main bus-bar, and moving contact is sleeved on
In contact pipe, contact pipe connects busbar in succession, and connection busbar is mounted on pole, and for contact pipe sleeve in insulating cylinder, insulating cylinder is another
Grounding static contact, grounding static contact connection earth bus are installed in one end, and moving contact is fixed equipped with screw, and moving contact is driven by screw
It is mobile, realize three-station function.
The main bus-bar is three-phase, and three-phase main bus-bar is vertical "-" type alignment placement.
The utility model tri-station isolating switch and bus connecting device are directly anchored to main bus-bar using static contact（Or
Main busbar）On, without using branch's busbar of transition, the accumulation of error is reduced, motion stability is reliable when moving contact is inserted into static contact；Subtract
Lack a large amount of switching link, save cost, simple to install, accuracy height.
