Abstract
The invention relates to an anti-misoperation device of a low voltage measuring cabinet. The anti-misoperation device comprises an isolation bracket which can be arranged on knife switches of a distribution board switch blade so as to effectively isolate an electrical part hung on the head of the switch blade, wherein an insulation connecting wire which can be connected with a ground wire is connected to the isolation bracket, the isolation bracket is a flat frame bracket, and two vertical partition boards are arranged in the middle of the flat frame bracket; a triangular connecting sheet is connected with a position between the two partition boards, and a connecting end part of the insulation connecting wire is in series connection with the triangular connecting sheet; the triangular connecting sheet is an isosceles triangle connecting sheet which is in inserted connection with corresponding inserting holes or grooves in the two partition boards through convex inserting end parts which are respectively arranged at two symmetrical angles, and a connecting end part of the insulation connecting wire is in series connection with the triangular vacancy position in the center of the isosceles triangle connecting sheet; the anti-misoperation device has the characteristics that the potential safety hazards due to misoperation caused by the condition that the low voltage measuring cabinet is powered off, an electric energy meter is exchanged, and a current transformer is exchanged are prevented.
Description
Technical field
What the present invention relates to is that the power failure of a kind of low-voltage metering cabinet is changed electric energy meter, changed the anti-misoperation apparatus of current transformer, belongs to the anti-misoperation technical field of low-voltage metering cabinet.
Background technology
Carry out low-temperature measurement distribution screen meter connect electricity exchange low-voltage current mutual inductor time usually need to pull open the total lock of user side switchboard, then on busbar, low-voltage current mutual inductor is exchanged, and the instrument of spanner and so on is often used when exchanging low-voltage current mutual inductor, because the upper and lower space of switchboard is little, and the position that instrument transformer is installed is little from the upper pile crown electro-mechanical part column pitch of the total lock of switchboard, therefore there is certain dangerous factor when changing instrument transformer.
Usually, when exchanging low-voltage current mutual inductor, under total lock of metering switchboard, one pair of earth connection hung by pile crown, one pair of earth connection is hung at the outgoing line side of metering switchboard, need to remove after work completes these two pairs of earth connections just can with lock power transmission, but in fact, during the rear power transmission that worked, staff can forget dismounting earth connection thus cause combined floodgate with ground, easily security incident occurs.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, can avoid and prevent, when low-voltage metering cabinet power failure replacing electric energy meter, replacing current transformer, misoperation occurs and the anti-misoperation apparatus bringing the low-voltage metering cabinet of potential safety hazard.
The object of the invention is to have come by following technical solution, a kind of anti-misoperation apparatus of low-voltage metering cabinet, it to comprise on a disconnecting link that can be placed in switchboard plug-in strip so that the isolation mount of effectively being kept apart at charged for hanging head on plug-in strip position, and this isolation mount is connected to an insulation connection cord that can be connected with earth connection.
Described isolation mount is a flat-shaped frame set, and the centre of this flat-shaped frame set is provided with two pieces of vertical dividing plates, and between two pieces of dividing plates, be connected to a triangle joint sheet, and this triangle joint sheet is serially connected with the connecting end portion of described insulation connection cord.
Triangle joint sheet of the present invention is isoceles triangle brace, this isoceles triangle brace, in the evagination grafting end arranged respectively by two the symmetric angle portions corresponding spliced eye that is plugged on described two pieces of dividing plates or groove, the middle triangle vacancy of described isoceles triangle brace is serially connected with the connecting end portion of described insulation connection cord.
It is simple that the present invention has structure, easy to use and reliable, misoperation occurs and brings the features such as potential safety hazard when can prevent low-voltage metering cabinet power failure from changing electric energy meter, replacing current transformer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is mounting structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, the anti-misoperation apparatus of low-voltage metering cabinet of the present invention, it to comprise on a disconnecting link 2 that can be placed in switchboard 1 plug-in strip so that the isolation mount 3 of effectively being kept apart at charged for hanging head on plug-in strip position, and this isolation mount 3 is connected to an insulation connection cord 5 that can be connected with earth connection 4.
Shown in Fig. 2, isolation mount 3 of the present invention is a flat-shaped frame set, the centre of this flat-shaped frame set is provided with two pieces of vertical dividing plates 6, and between two pieces of dividing plates 6, be connected to a triangle joint sheet 7, and this triangle joint sheet 7 is serially connected with the connecting end portion of described insulation connection cord 5.
Shown in figure, described triangle joint sheet 7 is isoceles triangle brace, this isoceles triangle brace, in the evagination grafting end 8 arranged respectively by two the symmetric angle portions corresponding spliced eye that is plugged on described two pieces of dividing plates 6 or groove 9, the middle triangle vacancy 10 of described isoceles triangle brace is serially connected with the connecting end portion of described insulation connection cord 5.
Spacing block insulating material of the present invention is made, and when pulling open the plug-in strip of switchboard, this spacing block is placed on disconnecting link and can be effectively kept apart at the charged position of pile crown on plug-in strip.And on this spacing block, having made an insulation connection cord, earth connection is connected with spacing block by this insulation connection cord, and take out spacing block when work completes power transmission, the connection cord on spacing block can remind you to remove earth connection, can effectively prevent combined floodgate with ground.
