Description
Technical field
The utility model relates to field of electrical equipment more particularly to a kind of safe attaching/detaching apparatus of transformer grounding pole.
Background technique
The ground connection resistance of transformer may will increase after 3 ~ 5 years, and ground resistance increase will lead to 3 phases 4
The drift of line route zero curve, therefore periodically detection ground connection resistance is essential work in electric power overhaul.It is existing
Some ground resistance maintenance directly disconnect ground line to be measured, then service ground line is connected, and then start to measure ground connection to be measured
Line ground resistance can generate zero curve drift disconnecting the service ground line 3 phase this period 4 line route to be measured that connects,
Zero curve drift will lead to the equipment after route and be burned out.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of safe attaching/detaching apparatus of transformer grounding pole is provided, with solution
The problem of certainly will lead to zero curve drift when measuring transformer ground connection resistance.
The technical solution of the utility model is: a kind of safe attaching/detaching apparatus of transformer grounding pole, including continuous earth line,
The safe attaching/detaching apparatus of the transformer grounding pole further includes temporary ground wire, conductive slide plate, permanently connected plate and interim connection
Plate, temporary connection plate are electrically connected with temporary ground wire, and permanently connected plate is electrically connected with continuous earth line, temporary connection plate and permanent
Pass through dismountable conductive slide plate connection between connecting plate.
Further, the safe attaching/detaching apparatus of the transformer grounding pole further includes the first bolt and the second bolt, conduction
The strip hole towards one end opening is equipped in the middle part of slide plate, permanently connected plate and temporary connection plate are equipped with screw hole, permanently connected plate
The first bolt of upper threaded connection is threadedly coupled the second bolt on temporary connection plate, and the first bolt and the second bolt pass through strip hole
Conductive slide plate is fixedly connected on permanently connected plate and temporary connection plate.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is electrically connected by the first connecting column with the first binding post, the second connecting column
It is electrically connected with the second binding post, is provided with diameter in the middle part of mobile slide plate and connect the first strip hole that column diameter matches with first, move
Dynamic slide plate lower part is provided with diameter and connect the second strip hole that column diameter matches with second, and the second strip hole lower edge is open,
First strip hole length is greater than the second strip hole length, will not zero curve drift when guaranteeing to measure ground connection resistance.This is practical
New structure is simple, easy to operate, dismounting when especially suitable for transformer grounding resistance measurement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1 permanently connected plate, 2 temporary connection plates, 301 conductive slide plates, 302 strip holes, 4 second bolts, 5 first spiral shells
Bolt, 6 continuous earth lines, 7 temporary ground wires, 8 transformer grounding lines, 9 transformers.
Specific embodiment
With reference to the accompanying drawing and utility model is described further in specific embodiment:
With reference to Fig. 1, a kind of safe attaching/detaching apparatus of transformer grounding pole, including continuous earth line 6, the transformer grounding
The safe attaching/detaching apparatus of pole further includes temporary ground wire 7, conductive slide plate 301, permanently connected plate 1 and temporary connection plate 2, is temporarily connected
Fishplate bar 2 is electrically connected with temporary ground wire 7, and permanently connected plate 1 is connect with 6 conducting wire of continuous earth line, temporary connection plate 2 with permanently connect
It is connected between fishplate bar 1 by dismountable conductive slide plate 301.In use, continuous earth line 1 is the ground connection of ground resistance to be measured
Line, permanently connected plate 1 are connect with continuous earth line 6, temporary ground wire 7 be temporary grounding ground line, temporary ground wire 7 with face
When connecting plate 2 connect.First by conductive 301 upward sliding of slide plate until 302 lower end of the first strip hole no longer contacts permanently before measurement
Connecting plate 1, and transformer grounding line 8 is connect with temporary connection plate 2, therefore transformer 9 is in ground state always, will not go out
Existing zero curve drift.
Further, the safe attaching/detaching apparatus of the transformer grounding pole further includes the first bolt 5 and the second bolt 4, is led
The strip hole 302 towards one end opening is equipped in the middle part of electric slide plate 301, permanently connected plate 1 and temporary connection plate 2 are equipped with screw hole,
It is threadedly coupled the first bolt 5 on permanently connected plate 1, the second bolt 4, the first bolt 5 and second are threadedly coupled on temporary connection plate 2
Conductive slide plate 301 is fixedly connected on permanently connected plate 1 and temporary connection plate 2 by bolt 4 by strip hole 302.Measurement is permanent
Used time when being grounded 6 ground resistance first unscrews the first bolt 5 and the second bolt 4, then conductive slide plate 301 is removed, and in this way may be used
Easily to disassemble and install conductive slide plate 301.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
