Description
Technical field
The invention belongs to power domain, particularly a kind of earthing device.
Background technology
Work requirements along with the large and medium-sized power equipments such as electric power network, power equipment, distribution line, transmission line and line maintenance, maintenance, the distant main earth terminal under power-transmission frame of working region scope of many equipment, cannot ensure personnel's personal safety of repair and maintenance work.
In existing substation grounding facility: 1, main earth electrode: be mainly the grounding system of equipment region in electrical network, syndeton is main equipment looped network ground connection; (being generally that equipment is connected with looped network main electrical scheme with device housings), if equipment need to be selected earth point, when this point is during as temporary grounding point, is easy in equipment ground bolted, to twist stripped thread or to twist into two parts, and causes ground plane unreliable.2, pole-footing and main electrical scheme: the shell of the ground connection such as all kinds of shaft towers in transformer station region, pole-footing, support porcelain vase is connected with looped network main electrical scheme, band iron (60 * 60mm) cross section, forbids punching and welding earth bolt on the cross section of regulation, affects ground plane.3, in terminal box and main electrical scheme: terminal box of transformer substation internal terminal is arranged, earth point, is mainly that cable connection and small current neutral grounding connect, and forbids main equipment and large current earthing ground connection on this earth point, prevents that large electric current from burning out earth electrode.< < electric power safety working regulation > > provides against and uses winding method ground connection, forbids by metal files, grinding and ground connection on earth point.
When existing power circuit and distribution ground connection, ignorant pole-footing bottom situation, does not know whether pole-footing ground connection meets the requirements; If be positioned at open field, there is no earth electrode, and be difficult to find interim earth electrode.
In view of above situation, be to be necessary to design a kind of multifunctional mobile external ground device, be adapted to the earthing of casing, working earthing, circuit and the protective earthing of various main equipments, can meet the large-scale ground protection work of above-mentioned this working region property.
Summary of the invention
The object of the present invention is to provide a kind of multifunctional mobile external ground device, to solve the problems of the technologies described above.
For achieving the above object, the present invention adopts following technical scheme:
A multifunctional mobile external ground device, comprises ground connection panel, grounding pin, screw mandrel, nut, upper cuff and lower cuff; The top of grounding pin is fixed on screw mandrel, and screw mandrel is provided with foot-driven lever; Nut sleeve is located at screw mandrel periphery and is formed a pair of leading screw and nut mechanism with screw mandrel, and nut is fixed on ground connection panel; Described nut is fixed on ground connection panel by upper cuff, lower cuff; Screw mandrel is provided with inlet channel, and the end of this inlet channel is provided with rhone; The top of screw mandrel is provided with allen wrench.
Preferably, the lower surface of ground connection panel is fixed with four supporting struts, and described supporting strut below is provided with pillar pad.
Preferably, described ground connection panel is provided with some slip earth electrodes.
Preferably, the length of grounding pin is greater than or equal to 80cm.
Compared with prior art, the present invention has the following advantages: the present invention is adapted to the assembling of transformer station and outlet line steel tower, is mainly to provide interim external ground measure in the earthing of casing of main equipment of external power supply and line construction.The major function of this device is to prevent thunderstorm, the personal injury of thunder and lightning to the shell of power tool and operating personnel, when rainy thunderstorm hour can be reliably by thunder and lightning drainage underground, guarantee safety work and the protective effect of operating personnel and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that high voltage transmission line tower connects the schematic diagram of apparatus of the present invention by earth connection.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
Refer to shown in Fig. 1 and Fig. 2, a kind of multifunctional mobile external ground of the present invention device, comprises ground connection panel 1, supporting strut 2, grounding pin 5, screw mandrel 6, cuff 9, nut 10 and spanner 11.
The top of grounding pin 5 is fixed on screw mandrel 6, and screw mandrel 6 is provided with foot-driven lever 61.During use, leading screw 6 and grounding pin 5 are connected, pin is stepped on foot-driven lever 61 makes grounding pin 5 pierce (80 centimetres of ground regulation points, if do not reach this size, can follow-uply with leading screw rotation, reach this size), after grounding pin 5 is substantially fixed, the cuff up and down 9 on ground connection panel 1 and ground connection panel 1 is installed and fixes the nut on screw mandrel 6 is fixed between upper and lower cuff 9, mounting flange 12, supporting strut 2 and pillar pad 3, complete whole installation processes simultaneously.
When grounding pin 5 can not complete 80 centimetres of pre-buried sizes with foot-driven lever 61, can be contained in screw mandrel 6 tops makes grounding pin 5 reach preliminary dimension object with allen wrench 11 rotary screws 6, when ground surface dust is subject to temperatures involved, can pour into little water by the inlet channel 7 on screw mandrel 6, water is along in rhone 8 inflow places of inlet channel 7 ends, can guarantee that underground is moist, reaches the reliable effect of ground connection.
Earthing device installs, and available earth resistance meter-measurement resistance meets < < safety > > condition, can use; Then by earth connection, be connected to the slip earth electrode 4 on ground connection panel 1, and fixing by earth stud 13, so that earth electrode is connected and can reaches application target with earth terminal, guarantee the person and device security.
The foregoing is only one embodiment of the present invention, it not whole or unique execution mode, the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading specification of the present invention, is claim of the present invention and contains.
