Abstract
The utility model discloses a high-voltage AC grounding switch, which comprises a lower conductive pipe and a fixed base arranged at the bottom end of the lower conductive pipe, wherein a support rod is arranged between the upper end of the lower conductive pipe and the position of the fixed base deviating from the center line of the lower conductive pipe. In the high-voltage AC grounding switch provided by the utility model, the support rod, the lower conductive pipe and the fixed base form a triangular support structure for stably and firmly supporting an upper conductive pipe, the requirement of external force such as electric motive power, wind power and the like when the high-voltage AC grounding switch bears through current can be met, and the utility model provides powerful assurance for the safety of maintenance personnel and maintained equipment. The utility model passes the verification of 5000 times of mechanical lifetime and 160kA of rated peak withstand current on JW5-1100 type grounding switches.
Description
Technical field
The utility model relates to high-voltage alternating electrical equipment equipment technical field, is specifically related to a kind of high voltage AC earthing switch.
Background technology
High voltage AC earthing switch is the equipment that safe and reliable ground connection is provided for the maintenance of high-voltage AC transmission circuit and high voltage power transmission equipment, to guarantee the safety of maintainer and repair apparatus.Present high voltage AC earthing switch comprises contact tube and following contact tube, and last contact tube is arranged on down the upper end of contact tube, and last contact tube and following contact tube all are slender type, so the height of whole upward contact tube and following contact tube is higher.And last contact tube and following contact tube in use also need to bear applied forces such as big electric power and wind-force, therefore very easily topple over, and stability is very poor, so there is very big potential safety hazard in existing high voltage AC earthing switch.
The utility model content
The purpose of this utility model provides high, the safe and reliable high voltage AC earthing switch of a kind of stability.
In order to realize above purpose, the technical scheme that high voltage AC earthing switch adopted that the utility model provides is: a kind of high voltage AC earthing switch, comprise following contact tube and be arranged on down the firm banking of contact tube bottom, between the position of the center line of contact tube under the departing from of the described upper end of descending contact tube and described firm banking, be provided with support bar.
Further, described support bar is made up of the connecting rod, insulation board and the support bar body that connect successively, and the free end of described connecting rod is fixedly arranged on down the upper end of contact tube, and the free end of described support bar body is fixedly arranged on the firm banking.
In the high voltage AC earthing switch that the utility model provides, support bar is formed a triangular support structure with following contact tube, firm banking, firmly supporting and going up contact tube, satisfied the requirement that high voltage AC earthing switch bears applied forces such as electric power when through-flow and wind-force, for the safety of maintainer and repair apparatus provides powerful guarantee.The utility model has passed through the checking of mechanical endurance 5000 times and Rated peak withstand current 160kA on JW5-1100 type earthed switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
In conjunction with Fig. 1, the utility model will be further described:
As shown in Figure 1, a kind of high voltage AC earthing switch that the utility model provides, comprise contact tube 5 and the firm banking 6 that is arranged on down the contact tube bottom down, between the position of the center line of contact tube under the departing from of the upper end of descending contact tube 5 and firm banking 6, be provided with support bar, support bar is made up of the connecting rod 1, insulation board 2 and the support bar body 3 that connect successively, the free end of connecting rod 1 is fixedly arranged on down the upper end of contact tube 5, and the free end of support bar body 3 is fixedly arranged on the firm banking 6.In the high voltage AC earthing switch that the utility model provides, support bar body 3, connecting rod 1 and insulation board 2 these threes' centerline is in same straight line, therefore the support bar of being made up of support bar body 3, connecting rod 1 and insulation board 2 is just in time formed a triangular support structure with following contact tube 5, firm banking 6, firmly supporting and going up contact tube 4, satisfied the requirement that high voltage AC earthing switch bears applied forces such as electric power when through-flow and wind-force, for the safety of maintainer and repair apparatus provides powerful guarantee.
