Description
Technical field
The utility model relates to the anti-outside destroy protective device of a kind of high-voltage transmission line pole tower, belongs to ultra-high-tension power transmission line repair and maintenance equipment technology field.
Background technology
High-voltage transmission line pole tower is requisite vitals in the electrical network, anti-outside destroy is the important leverage of electric line safety in production in the important repair and maintenance equipment technology of ultra-high-tension power transmission line field, and its safe operation is directly connected to the safety and stability of electrical network and to the reliability of customer power supply.This device is to utilize the protective sleeve of special construction to realize that electric power line pole tower prevents the outside destroy function.Facts have proved that only the safety of secure transmission line of electricity vitals shaft tower just can reach the purpose that power transmission and distribution are kept the safety in production, can prevent that the pernicious power-off event of large tracts of land from occuring.
Anti-outside destroy is the important process that ensures that electric power transmission ﹠ distribution process safety is produced.With other anti-outside destroy protective device high-voltage transmission line pole tower is not installed and is compared, this anti-outside destroy protective device has following characteristics: 1. only need the anti-outside destroy protective device of basis is embedded on the angle steel of high-voltage transmission line pole tower lower end and can plays a protective role; 2. mounting method is simple, rapid.
And generally being installed, anti-outside destroy protective device high-voltage transmission line pole tower performance prevents that the outside destroy performance is not good; use the utility model will effectively prevent high-voltage transmission line pole tower that the generation of transmission line of electricity accident occurs because of outside destroy; effectively ensure the power grid security production work, prevent that the pernicious power outage of large tracts of land from occuring.
Summary of the invention
The purpose of this utility model is; in order to prevent that effectively electric power line pole tower is subjected to outside destroy and causes the transmission line of electricity fluctuation of service; the large area blackout that causes; ensure the safety in production of high pressure transmission and distribution network, the utility model proposes the anti-outside destroy protective device of a kind of high-voltage transmission line pole tower.
The technical solution of the utility model is, utilizes the rubber protecting device of special construction, and its inner energy absorption piece of placing special construction realizes that electric power line pole tower prevents the outside destroy function.
The anti-outside destroy protective device of the utility model shaft tower is comprised of rubber sleeve 11 and energy absorption piece 12; Rubber sleeve 11 profiles are angle steel shape, and the inner chamber of angle steel shape is arranged in the rubber sleeve 11, and the in-built energy absorption piece 12 of inner chamber, rubber sleeve 11 external surfaces scribble Huang, white alternate reflectorised paint.The energy absorption piece can be converted into the angle steel shape with foil and insert in the rubber sleeve, or is filled in the rubber sleeve with fine sand or with quartz sand.
During use, as shown in Figure 1, the anti-outside destroy protective device of the utility model shaft tower is placed on the high-voltage transmission line pole tower angle steel, alternatively up and down is arranged.
The beneficial effects of the utility model are that the utility model device is installed on the high-voltage transmission line pole tower, can ensure electrical network power transmission and distribution safety, effectively prevents the pernicious power outage of large tracts of land because of the outside destroy initiation, improves electrical network power transmission and distribution safety in production level.This device has good elasticity, can tightly wale the electric power line pole tower angle steel, a large amount of external impact energy that absorb, it is strong, smooth attractive in appearance to have insulation, caution, protecting against shock, the characteristics such as convenience quick for installation, can absorb well the energy of outside destroy, prevention electric power line pole tower security incident occurs, and saves a large amount of maintenance costs.
The utility model is adapted at using on the power system high tension power line bar.
Description of drawings
Fig. 1 is that the utility model uses schematic diagram at the high-voltage transmission line pole tower angle steel;
Fig. 2 is the utility model structural representation;
Picture in picture number: the 1st, high-voltage transmission line pole tower is prevented the outside destroy protective device; The 2nd, the high-voltage transmission line pole tower slotted-angle shelving; The 11st, rubber sleeve; The 12nd, the energy absorption piece.
The specific embodiment
The specific embodiment of the present utility model as shown in Figure 2.
The anti-outside destroy protective device of present embodiment high-voltage transmission line pole tower is comprised of the energy absorption piece 12 of rubber sleeve 11.In the present embodiment, rubber sleeve 11 is made by vulcanized rubber material, and profile is the angle steel shape, its long 200 ㎜, and thickness 10 ㎜, width is suitable with electric power line pole tower angle steel width; The cavity of rubber sleeve 11 is filled out and is put fine sand as the energy absorption piece.Appearance at rubber sleeve 11 is coated with yellowish-white alternate reflection alarming lacquer.
During use, the anti-outside destroy protective device of the shaft tower that is filled with the protecting energy piece closely is placed with on the shaft tower angle steel, uses fixedly snap close fastening to get final product at slotted-angle shelving.Effectively promoted the anti-outside destroy performance of high-voltage transmission line pole tower.After the utility model is installed on the high-voltage transmission line pole tower angle steel, can prevent the pernicious power outage of large tracts of land because of the outside destroy initiation, improve electrical network power transmission and distribution safety in production level.
