Abstract
A quick ground switch device belonging to the technical field of high voltage switches comprises a housing, a crank arm, a moving contact, a contact pedestal and a guide sleeve, wherein, the crank arm is arranged in the housing and movably connected with one end of the moving contact; the guide sleeve is sleeved outside the moving contact and fixedly connected with the contact pedestal; and the contact pedestal is fixedly arranged in the housing. In the utility model, the transmission link is omitted, and the performance of the quick ground switch device is improved.
Description
Technical field
The utility model relates to a kind of device of high-voltage switch gear technical field, specifically is a kind of high speed grounding switch device.
Background technology
The high speed grounding switch device is an assembly of gas-insulated metal-enclosed combined electrical apparatus GIS, the outlet isolating switch that is configured in out line loop is by circuit one side, and it has two effects: folding parallel shelf ceases to be busy route produces inductive current in capacitance current and the electromagnetic induction that electrostatic induction produces; When creepage phenomenon or enclosure arcing appearred in the enclosure insulator, high speed grounding switch utilized circuit breaker excision fault current with the quick ground connection of major loop.
The high speed grounding switch device is of a great variety in the market, and great majority adopt the multistage transmission of connecting rod to realize the transmission of input work, and volume ratio is bigger, and cost is higher.
Find through retrieval prior art, Chinese patent publication number CN201122523 has put down in writing a kind of " high speed grounding switch that is used for High-Voltage Electrical Appliances ", and movable contact rod links to each other by the move power transmission shaft of spring operating mechanism of the first hinged connecting plate and second connecting plate and outer distribution in this technology.Drive by the electric spring operating mechanism of joining outward, realize branch, the function of closing a floodgate with cooperating of stationary contact headstock assembling thereby drive movable contact rod through power transmission shaft, second connecting plate, first connecting plate.But the two ends of first connecting plate respectively have one spacingly to be connected with movable contact rod with power transmission shaft respectively in the prior art, transmission link own is too many, motion credibility is poor, in motion process, if two spacing inaccuracy that cooperatively interact, be easy to cause the first connecting plate position stuck, serious meeting fractures it.For anti-incident here takes place less, will improve the quality of fit between first connecting plate and power transmission shaft and second connecting plate, will improve the material property and the machining accuracy of part like this, final result can cause the cost of product to improve.Transmission link is many, and required spatial volume is also big, equally also can increase product cost.
The utility model content
The utility model provides a kind of high speed grounding switch device at the prior art above shortcomings, has reduced transmission link, has improved the performance of high speed grounding switch device.
The utility model is achieved through the following technical solutions, the utility model comprises: shell, connecting lever, moving contact, contact base and fairlead, wherein: connecting lever rotates and to be arranged in the shell and to flexibly connect with an end of moving contact, fairlead is socketed on outside the moving contact and with contact base fixedlys connected, and contact base is fixedly set in the shell.
Described moving contact is provided with bracket, and this bracket and connecting lever are rotationally connected.
The contacted position of described contact base and shell is provided with insulating case.
Described bracket is for being catamaran type bolt shape structure, and the top of this bracket is provided with two relative horizontally-guided holes, and the bearing pin that described connecting lever end is provided with correspondingly-shaped is connected with the contact of horizontally-guided hole.
Described fairlead has two, is arranged at the top and the bottom of contact base respectively.
Compared with prior art, the utility model makes the movement locus of moving contact be limited in the middle of shell by having adopted the spacing of connecting lever and bracket, has just guaranteed good movement locus, thereby has improved the mechanical property of high speed grounding switch device.

Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: shell 1, connecting lever 2, moving contact 3, contact base 4 and fairlead 5, wherein: connecting lever 2 rotates and is arranged in the shell 1 and flexibly connects with an end of moving contact 3, fairlead 5 sockets are fixedlyed connected outward and with contact base 4 with moving contact 3, and contact base 4 is fixedly set in the shell 1.
Described moving contact 3 is provided with bracket 6, and this bracket 6 is rotationally connected with connecting lever 2.
Described contact base 4 is provided with insulating case 7 with shell 1 contacted position.
As shown in figures 1 and 3, described bracket 6 is for being catamaran type bolt shape structure, and these bracket 6 tops are provided with two relative horizontally-guided holes 8, and the bearing pin 9 that described connecting lever 2 ends are provided with correspondingly-shaped is connected with 8 contacts of horizontally-guided hole.
Described fairlead 5 has two, is arranged at the top and the bottom of contact base 4 respectively.
As shown in Figure 2, when swinging up and down, connecting lever 2 in the horizontally-guided hole 8 of bearing pin 9 on bracket 6 certain space that moves horizontally can be arranged, the effective like this horizontal thrust that when connecting lever 2 moves up and down bracket is produced that reduced, because bracket 6 and moving contact 3 connect as one, just reduced horizontal thrust to moving contact 3, make moving contact 3 mainly be subjected to component vertically downward, thereby guaranteed moving contact 3 vertical up-or-down movements, moving up and down of moving contact 3 is to finish in the space of contact base 4 and fairlead 5 qualifications.For moving contact 3, vertically stressed like this, the locus is limited in just having guaranteed good movement locus, thereby having improved the mechanical property of high speed grounding switch device in the middle of the shell 1.
