Description
Technical field
Have a power failure the present invention relates to a kind of low-voltage metering cabinet and change electric energy meter, change the anti-misoperation dress of current transformer
Put, belong to the anti-misoperation technical field of low-voltage metering cabinet.
Background technology
Carrying out low-temperature measurement distribution screen meter and connect usually to need to pull open user side when electricity exchanges low-voltage current mutual inductor to match somebody with somebody
The total lock of electric screen, then exchanges low-voltage current mutual inductor on busbar, and often uses spanner when exchanging low-voltage current mutual inductor
Etc instrument, because space is small above and below switchboard, and transformer install position it is powered from the upper pile crown of the total lock of switchboard
Position spacing is small, therefore certain dangerous factor is there is when changing transformer.
Generally, when exchanging low-voltage current mutual inductor, pile crown hangs one pair of ground wire under total lock of metering switchboard, in meter
Measure switchboard one pair of ground wire of outlet pendant, needed after the completion of work remove this two pairs of ground wires just can with lock power transmission,
But in fact, after the completion of work during power transmission, staff can forget to remove ground wire to cause combined floodgate with ground, easily occur
Security incident.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of simple in construction, it is easy to use can
Lean on, be avoided that and prevent low-voltage metering cabinet from having a power failure and occur maloperation when changing electric energy meter, changing current transformer and bring safety
The anti-misoperation apparatus of the low-voltage metering cabinet of hidden danger.
The purpose of the present invention is completed by following technical solution, a kind of anti-misoperation apparatus of low-voltage metering cabinet,
It, which includes one, can be placed on the disconnecting link of switchboard plug-in strip so as to the isolation branch for effectively keeping apart the powered position of hanging head on plug-in strip
Frame, is connected to an insulation connecting rope that can be connected with ground wire on the isolation mount.
Described isolation mount is a flat-shaped frame set, the centre of the flat-shaped frame set be provided with vertical two pieces every
Plate, and a triangle joint piece is connected between two pieces of dividing plates, the insulation connecting rope is serially connected with the triangle joint piece
Connect end.
Triangle joint piece of the present invention is isoceles triangle connection sheet, and the isoceles triangle connection sheet is symmetrical by two
The evagination grafting end that corner is set respectively is plugged in the corresponding spliced eye or groove of two pieces of dividing plates, the isoceles triangle
The connection end of the insulation connecting rope is serially connected with the middle triangle vacancy of connection sheet.
The present invention is easy to use and reliable with simple in construction, can prevent low-voltage metering cabinet from having a power failure change electric energy meter, change electricity
The features such as maloperation occurs during current transformer and potential safety hazard is brought.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the mounting structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Fig. 1, shown in 2, low-voltage metering cabinet of the present invention
Anti-misoperation apparatus, it include one can be placed on the disconnecting link 2 of the plug-in strip of switchboard 1 so as to effectively by the powered position of hanging head on plug-in strip every
The isolation mount 3 come is left, an insulation connecting rope 5 that can be connected with ground wire 4 is connected on the isolation mount 3.
Shown in Fig. 2, isolation mount 3 of the present invention is a flat-shaped frame set, and the centre of the flat-shaped frame set is set
Two pieces of vertical dividing plates 6 are equipped with, and a triangle joint piece 7 is connected between two pieces of dividing plates 6, are gone here and there on the triangle joint piece 7
It is connected to the connection end of the insulation connecting rope 5.
Shown in figure, described triangle joint piece 7 is isoceles triangle connection sheet, and the isoceles triangle connection sheet is by two
The evagination grafting end 8 that symmetrical angle part is not set is plugged in the corresponding spliced eye or groove 9 of two pieces of dividing plates 6, described
The connection end of the insulation connecting rope 5 is serially connected with the middle triangle vacancy 10 of isoceles triangle connection sheet.
Spacing block of the present invention is made with insulating materials, and when pulling open the plug-in strip of switchboard, this spacing block is placed on
Effectively the powered position of pile crown on plug-in strip can be kept apart on disconnecting link.And an insulation connection has been made on this spacing block
Rope, this insulation connecting rope connects ground wire and spacing block, and the connection on spacing block, spacing block is taken out when work completes power transmission
Rope can remind you to remove ground wire, can effectively prevent combined floodgate with ground.
Claims (2)
1. a kind of anti-misoperation apparatus of low-voltage metering cabinet, it is characterised in that：It, which includes one, can be placed in the disconnecting link of switchboard plug-in strip
