Abstract
The utility model relates to a spring applied to an outdoor high-voltage isolation switch. The spring applied to the outdoor high-voltage isolation switch comprises a spring body. The innovation points lie in that the external surface of the spring body is provided with an erosion resistant coating, and the erosion resistant coating is composed of an inner cold galvanized paint coating and an outer spring paint coating. The erosion resistant coating is composed of the inner cold galvanized paint coating and the outer spring paint coating, and double erosion resistant protection is used, thus the spring is not easy to rust when in use, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage isolating switch spring, particularly a kind of outdoor high-voltage isolating switch spring of long service life.
Background technology
Outdoor high-voltage isolating switch generally is installed on outdoor occasion, is directly exposed under the outside atmosphere environment, and it is exposed to outer spring easily corrosion after use a period of time.Traditional isolating switch adopts coating black electrophoretic paint technique behind the alramenting with spring, and it has certain antiseptic property, but it uses after a period of time with regard to corrosion, causes work unreliable, can not satisfy the electric power system instructions for use.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of outdoor high-voltage isolating switch spring of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of outdoor high-voltage isolating switch spring, comprise the spring body, its innovative point is: described this external surface of spring is provided with anticorrosive coat, and described anticorrosive coat is made of internal layer cold galvanizing dope layer and outer spring enamelled coating.
The utility model has the advantage of: anticorrosive coat is made of internal layer cold galvanizing dope layer and outer spring enamelled coating, adopts dual anti-corrosion protection, and spring is difficult for corrosion in use, increases the service life.
Description of drawings
Fig. 1 is the utility model outdoor high-voltage isolating switch spring structure schematic diagram.
Embodiment
As shown in Figure 1, comprise spring body 1, be provided with anticorrosive coat at spring body 1 outer surface, anticorrosive coat is made of internal layer cold galvanizing dope layer 2 and outer spring enamelled coating 3.When spring is made, adopt first dip-coating cold galvanizing coating to form internal layer internal layer cold galvanizing dope layer 2, the spray black spring coats with lacquer outer spring enamelled coating 3 and adopts dual anti-corrosion protection again, and spring is difficult for corrosion in use, increases the service life.
Claims (1)
1. an outdoor high-voltage isolating switch spring comprises the spring body, it is characterized in that: described this external surface of spring is provided with anticorrosive coat, and described anticorrosive coat is made of internal layer cold galvanizing dope layer and outer spring enamelled coating.
