Abstract
A kind of small operation instrument that can improve low pressure insurance installation and removal speed.Its L shaped platy structure for being made by insulating material, one bar limit is for inserting limit, and another limit is handle.The width of described handle is greater than the width that inserts limit, and the outer end of handle is formed with a circular hole.The small operation instrument of low pressure that what the utility model provided can improve insurance installation and removal speed can utilize lever principle that the spacing of junction draw-in groove is increased, it is convenient easy that thereby the installation and removal process that makes low pressure insurance becomes, therefore can improve operating condition, increase work efficiency and fail safe.In addition, this instrument also has simple in structure, low cost and other advantages.
Description
Technical field
The utility model belongs to electric power system auxiliary equipment technical field, particularly relates to a kind of small operation instrument that can improve low pressure insurance installation and removal speed.
Background technology
At present, the draw-in groove that some transformer station's mesolow once insures subsidiary signal contact junction is very tight, when the above-mentioned insurance of the each installation and removal of staff, all must use very large strength ability complete operation, and this contact is very near apart from live part, about 2 centimetres, and phase spacing is little, approximately only have 10 centimetres, therefore in aforesaid operations process, be easy to touch live part and damage equipment.In addition, because this contact is to utilize plastic material to make, after long-time running, it is can hardening aging, therefore exerts oneself when excessive to be easy to be broken, so exist larger potential safety hazard.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of small operation instrument that can improve low pressure insurance installation and removal speed.
In order to achieve the above object, the small operation instrument of low pressure that what the utility model provided can improve insurance installation and removal speed is the L shaped platy structure of being made up of insulating material, and one bar limit is for inserting limit, and another limit is handle.
The width of described handle is greater than the width that inserts limit, and the outer end of handle is formed with a circular hole.
The small operation instrument of low pressure that what the utility model provided can improve insurance installation and removal speed can utilize lever principle that the spacing of junction draw-in groove is increased, it is convenient easy that thereby the installation and removal process that makes low pressure insurance becomes, therefore can improve operating condition, increase work efficiency and fail safe.In addition, this instrument also has simple in structure, low cost and other advantages.
Brief description of the drawings
The small operation tool construction end view that can improve low pressure insurance installation and removal speed that Fig. 1 provides for the utility model.
Embodiment
The small operation instrument that can improve low pressure insurance installation and removal speed the utility model being provided below in conjunction with the drawings and specific embodiments is elaborated.
As shown in Figure 1, the small operation instrument of low pressure that what the utility model provided can improve insurance installation and removal speed is the L shaped platy structure of being made up of insulating material, and one bar limit is for inserting limit 1, and another limit is handle 2.
The width of described handle 2 is greater than the width that inserts limit 1, convenient operation like this, and the outer end of handle 2 is formed with a circular hole 3, can utilize this circular hole 3 that this instrument and other instrument are linked together, with anti-lost.
The small operation instrument using method that can improve low pressure insurance installation and removal speed now the utility model being provided is described below: in the time that needs mount and dismount transformer station's mesolow and once insure, first by staff, 1 outer end, the insertion limit on this instrument is inserted in the draw-in groove of signal contact junction, then handle 2 is rotated to 90 degree, insert 1 both sides of the edge, limit by large the width support of draw-in groove to utilize, at this moment just can insure and mount and dismount like a cork, after having operated, again handle 2 rotated to 90 degree and take out instrument.
