Abstract
The present invention relates to a kind of operating levers, and more particularly to a kind of insulating bar for shell type breaker, including operating lever, the top of the operating lever is equipped with concave and operates connector, are carrying out in use, concave operation connector sticks into the operating handle of shell type breaker.The insulating bar of the present invention can be used in the operation of common 380V on the market and following voltage class shell type breaker.
Description
Technical field
The present invention relates to a kind of operating levers, more particularly to a kind of insulating bar for shell type breaker.
Background technology
380V and following voltage class shell type breaker are operated, is that troubleshooting relatively conventional in power supply repairing works.
But so far, but without the Work tool designed exclusively for operation 380V and following voltage class shell type breaker.Currently, traditional operation
There are two types of modes for 380V and following voltage class shell type breaker.1, after having dressed protective articles by regulation, insulating glove is worn
Directly examination is sent., can be because of safe distance deficiency if there are failure, directly examinations to send for Switch main body, the electric arc meeting that breakdown switch generates
The person is damaged.2, it is operated using 10kV insulated operating rods, though it can allow Field Force and 380V and following voltage etc.
Grade shell type breaker keeps certain safe distance, but 10kV insulated operating rods body and 380V and the open circuit of following voltage class shell-type
Device operating handle mismatches, and displacement is easy in operating process, causes operation failure.Based on the above reason, develop universal
The insulating bar of 380V and following voltage class shell type breaker.
Invention content
The present invention is to solve above-mentioned technological deficiency, provides a kind of insulating bar for shell type breaker, this
The insulating bar of invention can be used in the operation of common 380V on the market and following voltage class shell type breaker.
The technical scheme is that；A kind of insulating bar for shell type breaker, including operating lever, the operation
The top of bar is equipped with concave and operates connector, is carrying out in use, concave operation connector sticks into the operation handlebar of shell type breaker
Hand.
It is carrying out in use, concave operation connector sticks into the operating handle of shell type breaker, the bar of operating lever dominated by hand
Body firmly makes concave operation connector withstand the operating handle of shell type breaker, you can the operating handle of shell type breaker is upward
It plays, realizes open-circuit operation.
Further, the width of concave operation connector is 4.7cm.Through statistical measurement, the low pressure shell type breaker of common 630A
Operating handle width is 3.8 centimetres, so concave operation connector design width is 4.7 centimetres.Therefore can be suitble to most of
Low pressure shell type breaker operates.
Further, operating lever is equipped with LED light, and the LED light is set to the lower section of concave operation connector.It, can with LED light
It can see operation object clearly in the power failure environment at night.
Further, the shaft part of operating lever is made of epoxide resin material, and guarantee has enough dielectric strengths.
Further, concave operation connector and is made using 3D printing technique using glass fibre as material.Glass fibers
Dimension is a kind of inorganic non-metallic material haveing excellent performance, and with good insulating, heat resistance is strong, corrosion resistance is good, high mechanical strength
The advantages of.And use 3D printing technique to make concave and operate connector, have and exempt to mold, low manufacture cost, manufacturing speed is fast, finished product
The features such as precision is high.
Further, operating lever includes telescopic operating lever.Using telescopic operating lever, keep the length of operating lever adjustable
Section, not only can guarantee enough safe distances, but also can reach best ergonomic.
The beneficial effects of the invention are as follows；
1, increase Field Force and 380V and the operating distance of following voltage class shell type breaker.It avoids because of safe distance
Deficiency, the electric arc that circuit breaker failure generates cause personal injury to Field Force.Greatly reduce security risk.
2, by the operating lever, using lever principle, Field Force can be more laborsaving and successfully operates large-scale shell-type
Breaker.
3, having filled up 380V and following voltage class shell type breaker does not have the blank of special operating tool.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
Embodiment 1：
As depicted in figs. 1 and 2, a kind of insulating bar for shell type breaker, including operating lever 1, the top of the operating lever 1
End is equipped with concave and operates connector 2, is carrying out in use, concave operation connector 2 sticks into the operating handle of shell type breaker.
In progress in use, concave operation connector 2 sticks into the operating handle of shell type breaker, operating lever 1 dominated by hand
Shaft firmly makes concave operation connector 2 withstand the operating handle of shell type breaker, you can by the operating handle of shell type breaker to
On play, realize open-circuit operation.
In the present embodiment, the width of concave operation connector 2 is 4.7cm.Through statistical measurement, the low pressure shell-type of common 630A
Breaker operator handle width is 3.8 centimetres, so it is 4.7 centimetres that concave operation connector 2, which designs width,.Therefore can be suitble to big absolutely
Most low pressure shell type breaker operations.
In the present embodiment, operating lever 1 is equipped with LED light 3, and the LED light 3 is set to the lower section of concave operation connector 2.It carries
LED light 3 can see operation object clearly in the power failure environment at night.
In the present embodiment, the shaft part of operating lever 1 is made of epoxide resin material, and guarantee has enough insulation strong
Degree.
In the present embodiment, concave operation connector 2 be using glass fibre as material, and using 3D printing technique make and
At.Glass fibre is a kind of inorganic non-metallic material haveing excellent performance, and with good insulating, heat resistance is strong, corrosion resistance is good, machine
