Abstract
The utility model relates to an auxiliary tool used for connecting an earth wire during the detection and maintenance of an air switch, in particular to an earth wire connecting tool of a low-voltage air switch. The earth wire connecting tool of the low-voltage air switch is characterized in that the earth wire connecting tool comprises an insulated rod (1) and a spring (5). One end of the insulated rod (1) is fixedly connected with a first conducting strip (6) as well as articulated with a second conducting strip (4). The two ends of the spring are respectively connected with the two conducting strips. A handle (2) is also mounted on the insulated rod (1), wherein the handle (2) is articulated on the insulated rod (1). One end of the handle (2) is connected with the second conducting strip (4) under the articulated connection by a pull wire (3), so that the handle (2) can be rotated to stretch the spring (5) as well as increase the distance between the two conducting strips. The utility model can effectively reduce the time of interruption maintenance of equipment, improves the working efficiency, lessens the time of the power failure of a user, greatly shortens the time of connecting the earth wire, and reduces the potential danger caused by the return of the power supply by the user.
Description
Technical field
Earth connection was used when the utility model related to the maintenance of a kind of low-voltage air switch aid, especially low-voltage air switch earth connection instrument.
Background technology
In recent years, along with being on the increase of 0.4kV low-voltage equipment maintenance task, also increase year by year to the operation in low pressure summary table case or the box change, carrying out a preceding important technique measure of formal operation is power failure, electrical verification and installing earth connection.
Install wherein that the present low-voltage circuit of earth connection continues to use always general earth connection instrument, the time that hangs is long, hanging unreliable is a very important problem, directly influences operating efficiency and threatens maintainer's life security.Hang method through the consistent general earth connection of continuing to use of the earth connection of electric power system low pressure in decades, can not adapt to current low-voltage air switch hanging earthing conductor and use; In the low pressure interruption maintenance work in every year, hanging earthing conductor influenced operating efficiency and repair time for up to 30 minutes sometimes; In maintenance process, find just only to draw back air switch when the part maintainer runs into difficult hanging earthing conductor, the hanging earthing conductor phenomenon does not happen occasionally, if user's foldback electricity threatens maintainer's life security.
The utility model content
Thereby the purpose of the utility model provides a kind of use and simply can effectively increase work efficiency, the low-voltage air switch earth connection instrument of support personnel's safety.
A kind of low-voltage air switch earth connection instrument; Its special feature is, comprises an insulating bar, and an end of this insulating bar is with also hinged with second conducting strip when first conducting strip is fixedly connected; Also comprise the spring that two ends are connected with two conducting strips respectively; The leader also is installed on insulating bar, and this handle is hinged on the insulating bar, makes the spacing of two conducting strips increase the while extension spring thereby an end of this handle is connected rotatable grip through draught line with the aforementioned second hinged conducting strip.
Thereby wherein all have the groove clamping object that cooperatively interacts on two conducting strips.
Wherein at least one conducting strip, binding post is installed.
Wherein conducting strip is copper sheet or aluminium flake.
The utility model can effectively reduce the equipment interruption maintenance time, has improved operating efficiency, has reduced customer outage hours, has shortened the hanging earthing conductor time greatly, also reduces the hidden danger of bringing because of user's foldback electricity.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model open configuration;
Accompanying drawing 2 is the structural representation of the utility model closure state.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing:
As shown in Figure 1; The utility model comprises an insulating bar 1; One end of this insulating bar 1 is with also hinged with second conducting strip 4 when first conducting strip 6 is fixedly connected, thus on two conducting strips during interlock the corresponding section all have the groove clamping object (hanging earthing conductor end to be measured) that cooperatively interacts.Also comprise the spring 5 that two ends are connected with two conducting strips respectively; Leader 2 also is installed on insulating bar 1; This handle 2 is hinged on the insulating bar 1, makes the spacing of two conducting strips increase while extension spring 5 thereby an end of this handle 2 is connected rotatable grip 2 through draught line 3 with the aforementioned second hinged conducting strip 4.
On at least one conducting strip, binding post is installed in addition, thus more convenient wiring, and conducting strip is copper sheet or aluminium flake, and is rectangular strip.
The utility model is depression of handle 2 in use, and draw back hinged conducting strip through draught line 3 this moment, again the groove between two conducting strips is stuck in hanging earthing conductor end to be measured and gets final product.Taking off back hinged conducting strip under the tension of spring 5 automatically resets.
Claims (4)
1. low-voltage air switch earth connection instrument; It is characterized in that: comprise an insulating bar (1); One end of this insulating bar (1) is with also hinged with second conducting strip (4) when first conducting strip (6) is fixedly connected; Also comprise the spring (5) that two ends are connected with two conducting strips respectively; Leader (2) also is installed on insulating bar (1), and this handle (2) is hinged on the insulating bar (1), an end of this handle (2) through draught line (3) with aforementioned hinged second conducting strip (4) thus being connected the spacing that rotatable grip (2) makes two conducting strips increases extension spring (5) simultaneously.
2. low-voltage air switch earth connection instrument as claimed in claim 1 is characterized in that: thus wherein all have the groove clamping object that cooperatively interacts on two conducting strips.
3. low-voltage air switch earth connection instrument as claimed in claim 1 is characterized in that: wherein at least one conducting strip, binding post is installed.
4. like any described low-voltage air switch earth connection instrument in the claim 1 to 3, it is characterized in that: wherein conducting strip is copper sheet or aluminium flake.
