Abstract
The utility model discloses a handcart type switch cabinet grounding rod and belongs to the middle and high voltage power transmission and distribution technology field. The handcart type switch cabinet grounding rod comprises a contact arm having conduction performance, wherein a top end of the contact arm is provided with a plum contact in matching with a static contact, a back end of the contact arm is connected with an overlapping member, a grounding cable hitching row is arranged between the contact arm and the overlapping member, and a back end of the overlapping member is connected with an insulation operation rod. Through the handcart type switch cabinet grounding rod, the grounding rod formed by the contact arm, the plum contact and the insulation operation rod is utilized, so grounding operation can be accomplished by only holding the grounding rod hitched with a grounding cable with a hand to enable the plum contact and the static contact in a contact box to realize complete contact matching during use. Compared with a grounding dolly, the handcart type switch cabinet grounding rod has properties of fewer components, simpler structure, lower manufacturing cost, smaller occupation space and more convenient operation.
Description
Technical field
The utility model relates to a kind of earth rod of handcart switch cabinet, belongs to mesohigh power transmission and distribution technical field.
Background technology
Under regular situation, switch-cabinet grounding is completed by the grounding trolley (see figure 1), and earth handcart is bent welding and assembled by steel plate, the bottom chassis car is equipped with four rollers, can move by along continuous straight runs, grounding contact also is housed, guider, locking mechanism and handcart turnover hand-operated mechanism device.When system being overhauled or is safeguarded, by maintaining car, grounding trolley is delivered to the test position in switch cubicle, the guide rail engagement of the propelling track of the roller on chassis vehicle and switch cabinet body both sides, interlocking by valve guide rail and valve roller, make earth handcart open valve, and move to service position, a moving contact that simultaneously drives handcart top is done to contact accordingly with car and fixed contact in cabinet, after earth handcart arrives service position, one time dynamic/static contact meshes fully, now earth connection is hung on the copper bar of three-phase short circuit, form grounding system, electric weight remaining in switch cubicle is imported to the earth, guarantee maintenance personal's safety.But sometimes, because switch cubicle is placed on, case becomes the inside or site space is limited, can't place or the operational grounding dolly, therefore brought very large inconvenience to execute-in-place, although also there is sometimes the space of placement or operational grounding dolly, because every ground connection cabinet all will be equipped with one, grounding trolley, can cause the waste of cost thus, therefore need a kind of operating means that can substitute grounding trolley.
Summary of the invention
It is small and exquisite that the technical problems to be solved in the utility model is to provide a kind of volume, can conveniently be grounded the earth rod of the handcart switch cabinet of operation.
In order to solve the problems of the technologies described above, the earth rod of handcart switch cabinet of the present utility model, comprise the contact arm with electric conductivity, and the top of contact arm is provided with one and coordinates Mume flower contact with fixed contact; The rear end of contact arm is connected with a bridge piece, is provided with an earth cable between contact arm and bridge piece and articulates row, and the rear end of bridge piece is connected with an eradication edge action bars.
Described insulating bar is the glass fiber winding pipe.
After adopting above-mentioned structure, due to the earth rod formed by contact arm, Mume flower contact and insulating bar arranged, thus in use, only need the hand-held earth rod that connects earth cable that articulated, make Mume flower contact contact cooperation fully with fixed contact in contact box, can complete the ground connection operation, with grounding trolley, compare, building block is few, simple in structure, and the processing and manufacturing cost is little, take up room little, use easy to operate.
The accompanying drawing explanation
The use status architecture schematic diagram of the earth rod that Fig. 1 is the utility model handcart switch cabinet;
The structural representation of the earth rod that Fig. 2 is the utility model handcart switch cabinet.
Embodiment
Below in conjunction with the drawings and specific embodiments, handcart switch cabinet of the present utility model is described in further detail.
As shown in the figure, handcart switch cabinet of the present utility model, comprise the contact arm 1 with electric conductivity, and the top of contact arm 1 is provided with one and coordinates Mume flower contact 2 with fixed contact; The rear end of contact arm 1 is connected with a bridge piece 3, be provided with an earth cable between contact arm 1 and bridge piece 3 and articulate row 4, the rear end of bridge piece 3 is connected with an eradication edge action bars 5, insulating bar 5 is the glass fiber winding pipe, the glass fiber winding pipe is to be soaked with after the epoxy composite gum forming by the non-twist synthetic glass fiber of alkali-free, through heating, solidify the insulated product form, have good electric property and mechanical performance, Jie consume low, indeformable, put the characteristics such as little, resistance to chemical attack without layering, office.
During use, after valve is opened, the hand-held earth rod that has articulated earth cable of people, send into it in handcart chamber 6 respectively, makes Mume flower contact 2 contact cooperation fully with fixed contact in contact box, completes the ground connection operation.
Claims (2)
1. the earth rod of a handcart switch cabinet, comprise the contact arm (1) with electric conductivity, and the top of described contact arm (1) is provided with one and coordinates Mume flower contact (2) with fixed contact; The rear end of described contact arm (1) is connected with a bridge piece (3), is provided with an earth cable between contact arm (1) and bridge piece (3) and articulates row (4), and the rear end of described bridge piece (3) is connected with an eradication edge action bars (5).
2. according to the earth rod of handcart switch cabinet claimed in claim 1, it is characterized in that: described insulating bar (5) is the glass fiber winding pipe.
