Description
Technical field
Invention belongs to field of power transmission, in particular to a kind of cable strain insulator device with warning function.
Background technique
Cable is fixed on utility poles, and after a period of time, cable is easy relaxation, gives the visual sense of insecurity of people；But
It is in some depopulated zones, people cannot have found those cables for needing to safeguard in time in time, cause some cables sagging serious, most
It is broken under cable self gravity, brings inconvenience to people's life eventually.
State license notification number CN106448952B authorizes publication date 20170811, and disclosing one kind, " Y type strain insulator is exhausted
Edge substring and anchor support "；It include: two strain insulator-strings, the first connection gold utensil, the first extending structure, the second connection gold utensil and first
Triangle yoke plate, the shape of the first triangle yoke plate are triangle；The apex angle of first triangle yoke plate passes sequentially through the first connection gold utensil,
One extending structure and the second connection gold utensil are connect with anchor support, and two base angles of the first triangle yoke plate are contacted with two strain insulators respectively
It connects.Anchor support includes the hanging point of Y type strain insulator string, and Y type strain insulator string is mounted on the hanging point；Although the invention reduces
The out-of-balance force of anchor support, but its scheme for not changing the prior art still, provide foot using the ductility of itself for cable
Enough tension, thus prevent cable sagging, but after a protracted use, cable is inevitably sagging, in human eye rareness
Area be easy to delay maximum maintenance opportunity, lack warning function.
Summary of the invention
The shortcomings that purpose of invention is to overcome the prior art to lack warning function adds warning device, when cable
When power declines, adjusting nut is resisted against in main body, and the closing of circuit of warning device, warning device sounds an alarm, and provides a kind of band
The cable strain insulator device of warning function.
Realization above-mentioned purpose, the invention adopts the following technical scheme:
A kind of cable strain insulator device with warning function, including strain insulator device, strain insulator device one end hingedly on utility poles,
The strain insulator device other end connecting cable, the strain insulator device lower section are equipped with telescopic device, and the telescopic device includes main body
And mandril, described mandril one end are hinged on strain insulator device, described main body one end hingedly on utility poles, the subject freedom end
