Abstract

The utility model discloses an open-loop grounding device used for electric equipment maintenance, which comprises a mounting panel, a grounding ring and a plurality of mounting holes; wherein the mounting panel and the grounding ring are connected vertically on the surface, the mounting hole is arranged on the mounting panel 1. With a comparatively larger contact surface of the mounting panel and the lower pile head and the adoption of the multi-hole fixation, the utility model will not be loosen even being long affected by natural conditions, thus reducing potential safety hazards; with the surface vertical connection of the grounding ring and the mounting panel, the arranged grounding ring is only extended a short length under the lower pile head, thus arranged grounding ring is hard to contact with other objects and the electrical failures can be avoided; the longitudinal length of the whole device is comparatively smaller; the grounding ring is improved to be an L-shaped open loop, thus making the structure simpler, the size smaller and the cost lower.

Description

Open-loop Grounding Devices Used For Maintenance Of Electrical Equipment

[technical field]

The utility model relates to the electric power apparatus examination device, relates in particular to the electric power apparatus examination earthing device.

[background technology]

During electric power apparatus examination; for guaranteeing maintenance personal's safety; must be earlier with device powers down; after the high-low pressure outage; carry out electrical verification again; during high voltage testing; should use the electroscope of corresponding high pressure grade, during electrical verification, the necessary qualified high tension insulating gloves of wearing test; on charging equipment, test earlier; really after handy, can carry out electrical verification with it, electrical verification work should pass in and out the line both sides at construction equipment and carry out; the electrical verification work of regulation outdoor distribution equipment; should under dry weather, carry out, after identifying certain no electricity, also will be with construction equipment ground connection and with three-phase shortcircuit; also can effectively protect staff's safety under the situation that prevents to send a telegram here suddenly; should be at construction equipment each may send electricity aspect attaching ground wires all, for double circuit power supply unit, at a certain bus disconnecting link of maintenance or isolating switch; during on-load switch; not only simultaneously two bus disconnecting links are drawn back, and all while hanging earthing conductors of disconnecting link two ends of should constructing.The ground connection of equipment is that ground wire is connected on the earthing device, and present earthing device comprises interconnective ground loop and mounting panel.Rectangle closed loop of the general employing of ground loop is opened an installing hole, and is solder-connected on the ground loop on the mounting panel.The contact-making surface of mounting panel and following pile crown is less in this structure, and the employing single hole fixes, and easily causes after influenced for a long time by natural conditions looseningly, causes potential safety hazard; Because adopt parallel connection between ground loop and the mounting panel, so being installed, the back ground loop below following pile crown, also stretches out long length, may collide with other object, cause and use electric fault; The longitudinal length of whole device is bigger; Simultaneously, adopt whole rectangle closed loop there is no need, cause the waste of material, make structure complicated.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, propose a kind of Open-loop Grounding Devices Used For Maintenance Of Electrical Equipment, mounting panel is bigger with the contact-making surface of following pile crown, adopts porous to fix, even influenced for a long time by natural conditions also to be difficult for causing loosening, reduced potential safety hazard; Be difficult for causing and use electric fault; Simple in structure, volume is little, and cost is low.

For achieving the above object, the utility model proposes a kind of Open-loop Grounding Devices Used For Maintenance Of Electrical Equipment, comprise mounting panel, ground loop and installing hole, carry out between described mounting panel and the ground loop that face is vertical to be connected, installing hole is arranged on the mounting panel.

As preferably, the number of described installing hole is at least two.

As preferably, the number of described installing hole is two.

As preferably, described ground loop is L shaped open loop.

The beneficial effects of the utility model: the contact-making surface of the utility model mounting panel and following pile crown is bigger, and adopts porous to fix simultaneously, even influenced for a long time by natural conditions also to be difficult for causing loosening, has reduced potential safety hazard; Because employing face vertically connects between ground loop and the mounting panel, so being installed, the back ground loop below following pile crown, only stretches out short length, be difficult for colliding with other object, avoided using electric fault; The longitudinal length of whole device is less; Ground loop is improved to L shaped open loop, makes structure simpler, volume is little, and cost is low.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

[embodiment]

Fig. 1 is the structural representation of the utility model Open-loop Grounding Devices Used For Maintenance Of Electrical Equipment; Fig. 2 is the left view of Fig. 1; Fig. 3 is the vertical view of Fig. 1.Comprise mounting panel 1, ground loop 2 and installing hole 3, carry out between described mounting panel 1 and the ground loop 2 that face is vertical to be connected, installing hole 3 is arranged on the mounting panel 1.Because ground loop 2 is connected on the mounting panel 1 with overlapping, so the longitudinal length of whole device is just less.Mounting panel 1 is bigger with the area of following pile crown, increases the number of installing hole 3 simultaneously, adopts two or more installing holes, makes to fix more firmly, is difficult for causing loosening.With existing rectangle closed loop is L shaped open loop, and both simple in structure, volume is little, has reduced cost again.

The foregoing description is to further specify of the present utility model, is not to concrete qualification of the present utility model, any structure after the utility model simple transformation is all belonged to protection range of the present utility model.
