Embodiment
Just as described in the background section, the comparatively difficulty of opening and closing operations of pole-mounted circuit breaker in current 10kV distribution line.
Inventor studies discovery, and this is that the installation direction of pole-mounted circuit breaker is arranged according to line due in 10kV distribution line.After general installation, the lever of pole-mounted circuit breaker has two positions: a side of close electric pole shaft or the outside at electric pole shaft.When the lever of pole-mounted circuit breaker is positioned at the outside of electric pole shaft, if want, pole-mounted circuit breaker is operated, need staff to stand on the cat ladder of electric pole, health is outward-dipping as possible, head is outer facing upward as possible, utilize lever to open and close pole-mounted circuit breaker, cause staff very painstaking.And, due in to the operating process of pole-mounted circuit breaker, staff's out-shift of gravity center, pin nails on easy slip at pin, causes the hidden danger that exists staff easily to fall.
In addition, because the lever of pole-mounted circuit breaker is positioned at staff's oblique upper, cause staff when to the operating of pole-mounted circuit breaker, the visual field is not good, especially when the volume of pole-mounted circuit breaker is larger, make staff can't see lever, can only be under ground staff's commander complete operation, operating efficiency is low, and difficulty is large.If run into the bad weathers such as sleet, or urgent operation at night, can be lower to the operating efficiency of pole-mounted circuit breaker, potential safety hazard is also larger.
In view of this, the utility model provides a kind of pole-mounted circuit breaker servicing unit, is applied to the pole-mounted circuit breaker in 10kV electrical network, and described pole-mounted circuit breaker is fixed on the side of electric pole in described electrical network, and described servicing unit comprises:
The fixture being fixedly connected with electric pole;
Be fixedly connected with bracing or strutting arrangement with described fixture, described bracing or strutting arrangement is arranged on the side of described electric pole, and be positioned at described pole-mounted circuit breaker under.
In the technical scheme that the utility model embodiment provides, described bracing or strutting arrangement is fixed on the side of described electric pole by fixture, and be positioned at described pole-mounted circuit breaker under, thereby make staff when pole-mounted circuit breaker is operated, can to described bracing or strutting arrangement, to pole-mounted circuit breaker, operate by described fixture station, and described bracing or strutting arrangement and pole-mounted circuit breaker are positioned at the same side of electric pole, and be positioned at pole-mounted circuit breaker under.Therefore, staff can operate pole-mounted circuit breaker after standing on bracing or strutting arrangement easily, thereby has reduced the operation easier of pole-mounted circuit breaker in current 10kV distribution line
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that.Therefore the utility model is not subject to the restriction of following public concrete enforcement.
The utility model embodiment provides a kind of pole-mounted circuit breaker servicing unit, is applied to the pole-mounted circuit breaker in 10kV electrical network, and described pole-mounted circuit breaker is fixed on the side of electric pole in described electrical network, and described servicing unit comprises: the fixture being fixedly connected with electric pole; Be fixedly connected with bracing or strutting arrangement with described fixture, described bracing or strutting arrangement is arranged on the side of described electric pole, and be positioned at described pole-mounted circuit breaker under.
As depicted in figs. 1 and 2, in an embodiment of the present utility model, described bracing or strutting arrangement is cat ladder 1, and described fixture is anchor ear.Wherein, described anchor ear comprises: be fixed on described electric pole anchor ear stiffener 201 with it; The anchor ear plate 202 being fixedly connected with described anchor ear stiffener 201; The cat ladder support 204 being fixedly connected with described anchor ear plate 202 by bolt 203.
In a specific embodiment of the present utility model, described cat ladder 1 adopts Anti-drop ladder, and length is not less than 2 meters, so that fixing safety belt.Preferred, the length of described cat ladder 1 is 2 meters, but the utility model do not limit this, as long as guarantee that the distance between top and the described pole-mounted circuit breaker of described cat ladder 1 is 4 meters, the distance between bottom and the ground of described cat ladder 1 is greater than 2 meters.
In this embodiment, described cat ladder 1 is fixed on the shaft of described electric pole by the anchor ear of three groups of band cat ladder supports, and be positioned at described pole-mounted circuit breaker under, thereby make staff when pole-mounted circuit breaker is operated, can stand to and be positioned on the cat ladder 1 under described pole-mounted circuit breaker, described pole-mounted circuit breaker is operated, thereby solved when pole-mounted circuit breaker is operated in prior art, need staff's health outward-dipping as possible, head is outer facing upward as possible, utilize lever to open and close pole-mounted circuit breaker, cause staff's problem very laboriously.
And due in the present embodiment, described cat ladder 1 be positioned at described pole-mounted circuit breaker under, therefore, when pole-mounted circuit breaker is operated on staff stands described cat ladder 1, the visual field is better, thereby has solved the volume of pole-mounted circuit breaker when larger, make staff can't see lever, can only be under ground staff's commander complete operation, operating efficiency is low, the problem that difficulty is large.
It should be noted that, in the present embodiment, because described cat ladder 1 is fixed on the shaft of described electric pole by the anchor ear of three groups of band cat ladder supports, therefore, the pole-mounted circuit breaker servicing unit that the present embodiment provides, can entirety around the shaft rotation of electric pole, thereby can also be applied to the electric pole of tape cable.
