Abstract
The utility model provides a lightning arrester of a transformer station. The lightning arrester comprises a firewall, wherein a frame column is mounted on the firewall, a steel pipe is mounted on the frame column at the middle position of the firewall, a wire drawing ring is mounted on the steel pipe, and a lightning wire is mounted on the wire drawing ring. The lightning arrester is advantageous in that: when the lightning arrester is in use, the steel pipe is set up on a middle frame column of the firewall at two sides of the main transformer of a half-indoor transformer station, and the lightning wire is disposed at the space above a main transformer device through the drawing ring on the steel pipe, so that lightning protection for the main transformer device is achieved. The lightning arrester is capable of fulfilling the lightning protection requirements of the main transformer device, simple in structure, and material-saving, thus engineering cost is reduced, construction is facilitated, construction time is shortened, and the floor area is reduced.
Description
Technical field
The utility model relates to a kind of lightning arrester, relates in particular to a kind of transformer station lightning arrester.
Background technology
At present, transformer station belongs to half indoor substation more, i.e. the outdoor layout of main transformer needs to adopt independent lightning rod associating arrangement to carry out lightning protection to the safe operation of equipment.Transformer station's Yao Zhan district diagonal of a for example main transformer capacity 3 × 50MVA is arranged two 30 meters of independent lightning rods, coating steel pipe structure.Because it is arranged in transformer station bight, nearer apart from enclosure wall and circumferential highway, from main transformer equipment away from.Lightning rod basis is darker, affects the construction of enclosure wall; From road close together, when 3 meters of <, take all to press measure; If can meet the demands time, project cost is high, construction is complicated, the duration is long, floor space is larger.Lightning rod from main transformer equipment away from, must increase needle body, could meet lightning protection requirement.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly in meeting main transformer equipment lightning protection requirement, can reduces project cost, convenient construction, reduction of erection time, minimizing floor space, can meet transformer station's lightning arrester of lightning protection requirement simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of transformer station lightning arrester, comprising: fire compartment wall, its feature is: on described fire compartment wall, frame column is installed, on fire compartment wall medium position frame column, steel pipe is installed, stay thimble is installed on steel pipe, lightning conducter is installed on stay thimble.
According to described transformer station's lightning arrester, its feature is: the material of described steel pipe is galvanized steel, be shaped as T-shaped, height 3～8 meters, preferred heights is 5 meters.
According to described transformer station's lightning arrester, its feature is: 3～8 of described stay thimble, preferably number is 3.
According to described transformer station's lightning arrester, its feature is: described lightning conducter uses aluminum-cladding stranded wire.
The utility model has the advantages that: the utility model is at the added steel pipe of establishing of fire compartment wall middle boxes trestle at the main transformer two ends of half indoor substation; tube material is selected the galvanized steel that conductive effect is good; steel pipe is shaped as T-shaped; then on main transformer equipment superjacent air space, set up lightning conducter by the stay thimble on steel pipe; lightning conducter is selected the good aluminum-cladding stranded wire of conductive effect, completes the lightning protection to main transformer equipment.The utility model is in meeting main transformer equipment lightning protection requirement, simple in structure and save material, and then reduces project cost, convenient construction, reduction of erection time, minimizing floor space.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described:
A kind of transformer station lightning arrester, as shown in Figure 1, 2, comprising: fire compartment wall 1, on described fire compartment wall 1, frame column 2 is installed, on fire compartment wall 1 medium position frame column 2, steel pipe 3 is installed, stay thimble 4 is installed on steel pipe 3, on stay thimble 4, lightning conducter is installed.
In the present embodiment: the material of described steel pipe 3 is galvanized steel, be shaped as T-shaped, height 3～8 meters, preferred heights is 5 meters.
In the present embodiment: the number of described stay thimble 4 is 3～8, preferably number is 3.
In the present embodiment: described lightning conducter uses aluminum-cladding stranded wire.
The beneficial effects of the utility model are: the utility model in use; on the fire compartment wall 1 middle boxes trestle 2 at the main transformer two ends of half indoor substation, set up T-shaped coating steel pipe 3; then on main transformer equipment superjacent air space, set up aluminum-cladding stranded wire lightning conducter by the stay thimble 4 on T-shaped coating steel pipe 3, complete the lightning protection to main transformer equipment.The utility model is in meeting main transformer equipment lightning protection requirement, simple in structure and save material, and then can reduce project cost, and cost-saving, convenient construction, reduction of erection time, minimizing floor space, every construction of transformer substation can be saved about 100,000 yuan of project cost.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection range are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection range of the present utility model.
