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.

Outdoor high-voltage isolating switch is that maximum a kind of High-Voltage Electrical Appliances are used in electric power system, and it and outdoor high voltage circuit breaker, outdoor high-voltage earthing switch form the main peripheral hardware primary equipment of transformer station.Outdoor high-voltage earthing switch supports the use with outdoor high-voltage isolating switch again, in most cases forms combined electrical apparatus with outdoor high-voltage isolating switch, the support of use high voltage isolator, porcelain vase, pedestal etc.Outdoor high-voltage earthing switch is to use when electric power system ground connection, for high-tension line when interruption maintenance to electric equipment reliable grounds such as the high voltage bus being overhauled, circuit breakers.But when ground switch earthing, when system breaks down and because all other reasonses make system charged, earthed switch just forms short circuit grounding point so, the huge dynamic current and the heat-stable current that now just require this earthed switch to bear.Some outdoor high-voltage isolating switchs earthed switch used can not meet the large capacity requirement of users to earthed switch far away at present.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of drive mechanism earthed switch, can solve the problem that existing earthed switch capacity can not be satisfied the demand, improve the dynamic current bearing of earthed switch and the ability of heat-stable current, guaranteed contact reliability and the integral installation quality of earthed switch.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of drive mechanism earthed switch, comprise isolating switch mounting bracket, on isolating switch mounting bracket, be installed with guide rail and isolating switch pedestal, drive link is flexibly connected with isolating switch pedestal, on drive link, cover has moving contact of grounding switch bar, the clips being fixed on moving contact of grounding switch bar is pulled by connection, support and be flexibly connected with isolating switch pedestal, clips is flexibly connected with being connected between pulling, connect pull with support between be flexibly connected, the roller that is arranged on moving contact of grounding switch bar outside matches with guide rail, static contact of grounding switch is fixed on the contact base of isolating switch.
On drive link, be equipped with a plurality of drive link rollers that match with moving contact of grounding switch bar.
The quantity of drive link roller is two.
Support and drive link are flexibly connected with isolating switch pedestal by pivot pin.
Isolating switch mounting bracket is the support that channel-section steel is made.
Drive mechanism earthed switch provided by the invention, beneficial effect is as follows:
1, the step that rotatablely moves merely of existing earthed switch is closed a floodgate to put in place to become in two steps close a floodgate and put in place, moving contact of grounding switch bar rotatablely moving and the middle not pause of rectilinear motion in separating brake and making process, the reliable insertion of having guaranteed moving contact with contact reliably, can solve the problem that existing earthed switch capacity can not be satisfied the demand, improve the dynamic current bearing of earthed switch and the ability of heat-stable current, guaranteed contact reliability and the integral installation quality of earthed switch.
2, simple in structure, can operate practical, safe and reliable.
3, be designed to moving contact of grounding switch bar moving linearly time guiding and positioning action, the accurate direction while guaranteeing moving contact of grounding switch bar moving linearly of drive link roller.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention, and now isolating switch is in gate-dividing state, and earthed switch is in open mode;
Fig. 2 is state diagram of the present invention, and now isolating switch is in gate-dividing state, and moving contact of grounding switch bar does not also insert fixed contact after rotating approximately 65 °;
Fig. 3 is the enlarged drawing at Fig. 2 A of the present invention place;
Fig. 4 is state diagram of the present invention, and now isolating switch is in gate-dividing state, and moving contact of grounding switch bar inserts fixed contact, and earthed switch is in "on" position.
Embodiment
As shown in figures 1 and 3, the present invention includes isolating switch mounting bracket 13, on isolating switch mounting bracket 13, be installed with guide rail 10 and isolating switch pedestal 12, drive link 9 is flexibly connected with isolating switch pedestal 12, on drive link 9, cover has moving contact of grounding switch bar 3, the clips 5 being fixed on moving contact of grounding switch bar 3 pulls 6 by connection, supporting 8 is flexibly connected with isolating switch pedestal 12, clips 5 is flexibly connected with being connected between pulling 6, connect pull 6 with support 8 between be flexibly connected, the roller 7 that is arranged on moving contact of grounding switch bar 3 outsides matches with guide rail 10, static contact of grounding switch 2 is fixed on the contact base 1 of isolating switch.
On drive link 9, be equipped with a plurality of drive link rollers 4 that match with moving contact of grounding switch bar 3.
The quantity of drive link roller 4 is two.
Support 8 and drive link 9 are flexibly connected with isolating switch pedestal 12 by pivot pin 11.
The support that isolating 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, roller 7 on moving contact of grounding switch bar 3 makes moving contact of grounding switch bar 3 when rotating, keep certain direction and spacing to moving contact of grounding switch bar by being fixed on the arc-shaped edges of the guide rail 10 on isolating switch mounting bracket 13, when operating mechanism completes 70% stroke of whole action, moving contact of grounding switch bar rotates approximately 65 ° and contacts with the spacing fingertip of static contact of grounding switch 2.At this moment moving contact of grounding switch bar 3 completes the first step and rotate in place, and motion process is as shown in Fig. 1 → Fig. 2.
