Abstract
The utility model relates to a box -type substation box body ground connection protection device, including connecting seat, protective wire, earth connection and bolt, the one end earth connection of protective wire passes through the bolt fastening and is connected with box -type substation box body's metal casing, transformer and height, low -voltage cabinet casing at connecting seat, the other end of protective wire, the other end of earth connection is connected with the grounding body. The metal sheet book of connecting seat after by 30 -50mm is held and is formed, and including bottom plate and two curb plates, two curb plates are 90 with the contained angle of bottom plate. Be equipped with two bolt holes in the middle part of the bottom plate for the fixed connection seat, be equipped with three bolt hole on every curb plate, be equipped with the internal thread identical with the bolt in the bolt hole. The beneficial effects of the utility model are that, simple structure, simple to operate, swift, the security is high, reduces the emergence of electric shock accidents.
Description
Technical field:
The utility model relates to a kind of earth protective device, particularly relates to a kind of box for box-type transformer substation earth protective device.
Background technology:
Earth connection is exactly the line directly connecting the earth, also can be called safety return circuit line, and time dangerous, it just switches through high voltage direct and marries the earth, a lifeline at last.Box for box-type transformer substation, because insulation property are bad or environment for use is moist, can cause its shell, transformer and high and low pressure cabinet housing with electricity, electric shock accidents can occur time serious.In order to avoid the accident occurred can connect each wire at the metal shell of box-type substation, transformer and high and low pressure cabinet housing upper face, by the other end of electric wire access the earth, electrostatic can be brought into the earth once electrical equipment generation electric leakage earth connection and discharge.Because the empty room in box for box-type transformer substation is little, electric wire too much will seem in disorder, installs inconvenience, also has potential safety hazard.
Summary of the invention:
It is simple that the purpose of this utility model is to provide a kind of structure, easy for installation, the box for box-type transformer substation earth protective device that fail safe is high.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of box for box-type transformer substation earth protective device, comprise Connection Block, protective wire, earth connection and bolt, one terminate ground wire of protective wire is bolted on Connection Block, and the other end of protective wire is connected with the metal shell of box for box-type transformer substation, transformer and high and low pressure cabinet housing; The other end of earth connection is connected with earth electrode.
Described Connection Block is rolled over to hold by the metallic plate after 30-50mm and is formed, and comprise base plate and two side plates, the angle of two side plates and base plate is 90 °.Portion is provided with two bolts hole in the soleplate, in order to fixed connecting base; Each side plate is provided with three bolts hole, in bolt hole, is provided with the internal thread matched with bolt.
The two ends of described protective wire respectively connect a round-meshed connector, are convenient to connect.
Described earth connection is that annealed copper wire adopts that multiply high-quality annealed copper wire is stranded to be formed, and covers softness, resistant to elevated temperatures transparent insulation sheath outward, can prevent the wearing and tearing to ground connection copper cash in using.One end of earth connection is connected with connector, and be fixed on Connection Block, the other end is connected with earth electrode.
Further, described earth electrode is taper earth electrode, is convenient to insert underground, easy for installation.
The beneficial effects of the utility model are, structure is simple, and easy for installation, quick, fail safe is high, reduce the generation of electric shock accidents.
