Abstract
The utility model discloses a middle contact connection structure of earthing switch is kept apart to three stations, including middle contact seat, guide ring, spiral spring, moving contact, rack, gear, spacing ring etc, the utility model discloses in, can prevent through the both sides spacing ring that the gear from rocking about, still effectively prevent gear and middle contact seat direct contact when increasing gear move stability, eliminated the danger that produces metal cuttings.
Description
Technical field
This utility model belongs to high-voltage switch gear technical field and in particular to a kind of three-station isolating grounding switch Interposer contact
Attachment means.
Background technology
At present, the transmission between three-station isolating grounding switch rotating shaft and moving contact mainly has linear type rack-and-pinion to pass
Several forms such as dynamic, oscillating-type transmission and ball leading screw driving.Linear type rack pinion therein adopts gear rotating band
Dynamic it is contained in moving contact upper rack and carries out moving along a straight line to realize " combined floodgate-separating brake-ground connection " three of three-station isolating grounding switch
Plant working condition, general increased scratch-resistant material in gear both sides, does not make spacing process to gear both sides direction, when three works
Position isolation earthing switch still can produce metal break flour in switch operating state procedure because of friction, and this is to high-tension switch gear
For be fatal；The isolation earthing switch of oscillating-type transmission to realize three stations using moving contact around insulation rotating shaft rotary oscillation
Three kinds of working conditions of isolation earthing switch, this structure is simple because of its transmission, and installing space is little and isolation grounding static contact can
It is subject to designer to favor with various angles arrangement, but because isolation ground connection dynamic/static contact to dock plug by rotation, right
The matching requirements of three-station isolating grounding switch are higher, due to employing blade plug-in type contact, can make in use
Contact shape produces corner angle thus Electric Field Distribution can be caused uneven, the insulating properties of impact three-station isolating grounding switch；Ball
The three-station isolating grounding switch of screw rod transmission rotarily drives moving contact movement by screw mandrel and realizes three kinds of working conditions, this transmission
Directly simple, take up room little, but overall drive mechanism is complicated, the centering requirement to dynamic/static contact is very high, and economy is not high enough.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of simple and compact for structure, and overall volume is little, with
Shi Youxiao completely cuts off the unsafe condition that three-station isolating grounding switch course of action produces metal break flour.
Technical solutions of the utility model are：One kind is used for three-station isolating grounding switch Interposer contact attachment structure, including
Interposer contact seat, guide ring, spring touch finger, moving contact, tooth bar, gear, spacing ring etc..
Described Interposer contact seat, built with moving contact, passes through some spring touch fingers between the two and realizes electrical connection, by leading
Carry out guide-localization to ring；Moving contact, built with tooth bar, is fixed using elastic cylindrical pin between the two；Interposer contact seat built with
Gear, gear both sides respectively equipped with a spacing ring, in three-station isolating grounding switch course of action, by both sides spacing ring both
Effectively prevent gear and Interposer contact seat directly contact, eliminate the danger producing metal break flour, again can effective limiting gear
, it is ensured that the stability of transmission, using the nonmetallic materials of low-friction coefficient, power attenuation is extremely low for spacing ring simultaneously for double swerve.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the A-A sectional view of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described：
As shown in Figure 1, 2, the present embodiment includes Interposer contact seat unit 1, moving-contact unit 2 and gear transmission unit 3.
Interposer contact seat unit 1 includes Interposer contact seat 11, guide ring 12 and spring touch finger 13, described guide ring 12 and bullet
Spring fingertip 13 is incorporated on Interposer contact seat；
Moving-contact unit 2 includes tooth bar 21, moving contact 22 and elastic cylindrical pin 23, and it is solid that tooth bar 21 passes through elastic cylindrical pin 23
On moving contact 22.Moving-contact unit is loaded on the motion guaranteeing moving-contact unit 2 in Interposer contact seat 11 by guide ring 12
Direction and kinetic stability, realize moving contact 22 and the electrical connection of Interposer contact seat 11 by spring touch finger 13.
Gear transmission unit 3 includes gear 31, spacing ring 32, and gear 31 is loaded on Interposer contact seat 11 inside and moving contact
Tooth bar 21 in unit 2 engages each other, and rotarily drives rack linear motion by gear, realizes " opening, isolating isolation splice grafting
Open ground connection to open, keep apart ground connection and close " three kinds of operating modes；Gear 31 both sides respectively are used for preventing from shaking about gear equipped with a spacing ring 32
Dynamic, also effectively prevent gear 31 and Interposer contact seat 11 directly contact while increasing gear movement stability, eliminate generation
The danger of metal break flour.
