Abstract
The invention relates to an electric grounding switch, namely a power assisting device of a high-voltage grounding isolating switch. The switch comprises a switch bracket, wherein a conductive rod is coupled on the bracket, a ground knife box is arranged beside the conductive rod, a front end support of the ground knife box is clamped on the conductive rod, and the tail end of the ground knife box is coupled on the bracket. The tail end of the ground cutter box is welded with a threaded lead screw, and a gravity module is assembled and fixed on the threaded lead screw. The balance weight is additionally arranged at the tail end of the conducting rod of the isolating switch, the switching-on and switching-off operating force of the modified grounding isolating switch is obviously improved and balanced compared with the original switching-on and switching-off operating force, the safety and stability of the operation of equipment are improved, and the grounding isolating switch has the characteristics of flexible operation, light weight, labor saving and reliable switching-on and switching-off.
Description
Technical field
The present invention relates to a kind of switch power ground, i.e. the high-voltage grounding isolating switch power assisting device.
Background technology
In the prior art; JW-252 (W) type high-voltage grounding isolating switch is to exchange 50Hz outdoor high-voltage electrical equipment conventional equipment; This product can independently be installed in the electric power system; Supply high-tension line when the maintenance electric equipment, to guarantee personal safety and carry out the usefulness of ground connection, satisfy needs with it usually the upper strata busbar grounding.High-voltage grounding isolating switch adopts single pole distribution action type structure, comprises CS20-(X) type hand-power operating mechanism, switch bracket; Be connected with conducting rod on the support, the conducting rod side has ground cutter box, and ground cutter box front end holder is connected on the conducting rod; Ground cutter box terminal shaft is connected on the support, in the ground cutter box groove box tension spring is arranged, and it is little to have an operating physical force; Contact is reliable, is easy to advantages such as layout.For satisfying the different needs of power department, post insulator adopts multiple pattern, supplies the user to select.Because environmental condition long terms such as weather, temperature influence; Tension spring generation corrosion and rigidity are weakened; Thereby cause the elastic coefficient to reduce year by year; Thereby on-the-spot often occur that operation is dumb during to isolator operation, loose contact and divide-shut brake incomplete phenomena, have a strong impact on field operation personnel's safety.
Summary of the invention
The objective of the invention is provides a kind of architecture advances, the better high-voltage grounding isolating switch power assisting device of result of use to above-mentioned deficiency.
Technical solution of the present invention is: the high-voltage grounding isolating switch power assisting device comprises switch bracket, is connected with conducting rod on the support, and the conducting rod side has ground cutter box, and ground cutter box front end holder is connected on the conducting rod, and ground cutter box terminal shaft is connected on the support.Ground cutter box end is welded with threaded screw rod, assembles and be fixed with the gravity module on the threaded screw rod.Utilize lever principle, install counterweight additional, replace spring tension, cancelled in the ground cutter box groove box tension spring is arranged, overcome shortcoming in the prior art with the counterweight self gravitation at the conducting rod end.
Advantage of the present invention is: install counterweight additional at isolating switch conducting rod end; Improved earthing isolator branch, closing operation power had clear improvement more originally and are balanced; Improve the fail safe stability of equipment operation, had flexible operation, light laborsaving, divide-shut brake reliable characteristics.
To combine accompanying drawing that execution mode of the present invention is described in further detail below.
Description of drawings
Fig. 1 is a structure diagram of the present invention.
Fig. 2 is a ground cutter box structure diagram.
Embodiment
Referring to Fig. 1,2; The high-voltage grounding isolating switch power assisting device comprises switch bracket 1, and be coupling on the support 1 (being connected with support 1 through axostylus axostyle) has conducting rod 2, conducting rod 2 sides that ground cutter box 3 is arranged; Ground cutter box 3 front end holders are connected on the conducting rod 2, and ground cutter box 3 terminal shafts are connected on the support 1.Ground cutter box 3 ends are welded with " L " type threaded screw rod 5, assemble and be fixed with gravity module 4 on it, can the reasonable disposition counterpoise.Fig. 1 is conducting rod 2 released states.The present invention can transform JW-252 (W) type high-voltage grounding isolating switch on the market, to improve the flexibility of stable equipment operation property and operation.According to of the distance comparison of on-the-spot earthing isolator conducting rod 2, can regulate the arm of force of gravity module 4 to support 1 strong point and the quality of gravity module 4 and come the reasonable disposition counterweight with equipment frame and support 1.Gravity module 4 adopts high-density concrete to process (being not limited thereto, also can be other material), and adopts zinc-plated threaded screw rod and fixed by nut, so not fragile, corrosion are convenient to safeguard and dismounting the adjustment of being more convenient for.Operation principle: during electric equipments such as maintenance bus or bus isolating switch,, need to close a floodgate to guarantee the bus reliable ground for guaranteeing operating personnel's safety; At this moment actuating hand-power operating mechanism lifts with the bus bar side fixed contact conducting rod 2 left ends and reliably contacts, and lifts in the process at conducting rod 2; Because the counterweight effect is arranged thereafter; Lift very convenient laborsaving (otherwise, during separation too), and pass in time; Counterweight (gravity module 4) does not influence conducting rod 2 rises and falls, so this structure is very reasonable, suitable.
