Abstract
The invention relates to a transmission structure-based grounding switch comprising a disconnecting switch mounting support. A guide rail and a disconnecting switch pedestal are fixedly installed at the disconnecting switch mounting support. A transmission rod is movably connected with the disconnecting switch pedestal; and a grounding switch moving contact rod is sleeved at the transmission rod. A fixed hoop fixed at the grounding switch moving contact rod is movably connected with the disconnecting switch pedestal by a connecting plate and a support. A roller installed outside the grounding switch moving contact rod cooperates with the guide rail. A grounding switch static contact is fixed at a contact seat of a disconnecting switch. According to the invention, the pure rotation motion of the existing grounding switch is changed from one-step closing for being in place to two-step closing for being in place, thereby ensuring the contact reliability and the whole installation quality of the grounding switch. The capability of bearing of the dynamic stable current and the thermal stable current of the grounding switch can be improved; and a problem that the capacity of the existing grounding switch can not meet the requirement can be solved.

Disconnecting switch mounting bracket, disconnecting switch mounting bracket is installed with guide rail and disconnecting switch pedestal, drive link and isolation
Switch base is flexibly connected, and drive link is cased with moving contact of grounding switch bar, is fixed on the fixation on moving contact of grounding switch bar
Hoop by connecting plate, support is connected with disconnecting switch base runner, be flexibly connected between clips and connecting plate, connecting plate and prop up
It is flexibly connected between support, be arranged on the roller outside moving contact of grounding switch bar and match with guide rail, static contact of grounding switch is solid
It is scheduled on the contact base of disconnecting switch.
Multiple drive link rollers being matched with moving contact of grounding switch bar are equipped with drive link.
The quantity of drive link roller is two.
Support and drive link is connected with disconnecting switch base runner by pivot pin.
The support that disconnecting switch mounting bracket is made for channel-section steel.
The drive mechanism earthed switch that the present invention provides, has the beneficial effect that：
1st, the simple rotary motion one step in-place closing of existing earthed switch is changed into in-place closing in two steps, ground connection is opened
Close not do not pause in the middle of rotary motion in separating brake and making process for the movable contact rod and linear motion it is ensured that moving contact can
By inserting and reliably contacting, can solve the problems, such as that existing earthed switch capacity can not meet needs, improve earthed switch
The dynamic current bearing and heat-stable current ability it is ensured that the contact reliability of earthed switch and integral installation matter
Amount.
2nd, structure is simple, operable practical, safe and reliable.
3rd, drive link roller be designed as moving contact of grounding switch bar for linear motion when guiding and positioning action it is ensured that connecing
Accurate direction when ground switch movable contact head rod is for linear motion.

Fig. 1 is the structural representation of the present invention, and now disconnecting switch is in gate-dividing state, and earthed switch is in open shape
State；
Fig. 2 is the state diagram of the present invention, and now disconnecting switch is in gate-dividing state, and moving contact of grounding switch bar rotates about
Also it is not inserted into static contact after 65 °；
Fig. 3 is the enlarged drawing at Fig. 2A of the present invention；
Fig. 4 is the state diagram of the present invention, and now disconnecting switch is in gate-dividing state, and moving contact of grounding switch bar inserts stationary contact
Head, earthed switch is in "on" position.
Specific embodiment
As shown in figures 1 and 3, the present invention includes disconnecting switch mounting bracket 13, fixing in disconnecting switch mounting bracket 13
Guide rail 10 and disconnecting switch pedestal 12 are installed, drive link 9 is flexibly connected with disconnecting switch pedestal 12, and drive link 9 is cased with connecing
Ground switch movable contact head rod 3, the clips 5 being fixed on moving contact of grounding switch bar 3 pass through connecting plate 6, support 8 and disconnecting switch
Pedestal 12 is flexibly connected, and is flexibly connected between clips 5 and connecting plate 6, and connecting plate 6 is flexibly connected between 8 with supporting, and is arranged on
Roller 7 outside moving contact of grounding switch bar 3 is matched with guide rail 10, and static contact of grounding switch 2 is fixed on touching of disconnecting switch
On headstock 1.
Multiple drive link rollers 4 being matched with moving contact of grounding switch bar 3 are equipped with drive link 9.
The quantity of drive link roller 4 is two.
Support 8 and drive link 9 are flexibly connected with disconnecting switch pedestal 12 by pivot pin 11.
The support that disconnecting switch mounting bracket 13 is made for channel-section steel.
The course of work of the present invention is as follows：
（1）Making process：
A, drive link 9 rotate under the drive of earthing switch operating mechanism, the rolling on moving contact of grounding switch bar 3
The arc-shaped edges of wheel 7 guide rails 10 by being fixed in disconnecting switch mounting bracket 13 make moving contact of grounding switch bar 3 rotate
Certain direction and spacing to moving contact of grounding switch bar, when operating mechanism completes 70% stroke of whole action is kept during motion
When, moving contact of grounding switch bar is rotated about 65 ° and is contacted with the spacing fingertip of static contact of grounding switch 2.At this moment earthed switch moves and touches
Head rod 3 completes the first step and rotate in place, and motion process is as shown in Fig. 1 → Fig. 2.
B, after operating mechanism continuation action during 30% stroke, moving contact of grounding switch bar 3 is supporting 8, connecting plate 6 and
