Description

A kind of short-circuit line applied to Substation Electric Equipment mutual inductor secondary terminals
Technical field
The utility model belongs to electrical equipment operation and maintenance tools field, is related specifically to a kind of Substation Electric Equipment mutual inductor Operation and maintenance tools.
Background technique
Currently, electrical test personnel carry out ac voltage withstanding test to substation's GIS combination electric appliance, inversed current transformer When, to prevent mutual inductor secondary winding from opening a way, high voltage is incuded during pressure resistance and damages electrical equipment, is needed its is secondary Winding terminals short circuit grounding, usually short circuit secondary winding carry out short circuit using metal bare copper wire.Therefore there are problems that two kinds: 1, GIS combination electric appliance, Current Transformer Secondary terminal are intensive, are easy to appear the bad situation of shorted contacts, influence to test safety; 2, secondary terminals short circuit grounding, but terminals terminal is smaller, is unfavorable for testing crew work, and short-circuiting terminal is time-consuming and laborious, influences Test efficiency.
In order to when making GIS combined electric, secondary winding in current transformer short circuit short-circuit line contact with secondary terminals it is good, can Lean on, safety, guarantee test safety, save test period, the prior art need to develop it is a kind of can be by GIS combination electric appliance, electric current The experiment auxiliary device of mutual inductor secondary winding short circuit
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of electric operation short-circuit line, make GIS combined electric, Short-circuit line contacts good, reliable, safety, guarantee test safety, section with secondary terminals when secondary winding in current transformer short circuit Save test period.
To realize the above-mentioned technical purpose, the utility model provides a kind of applied to Substation Electric Equipment mutual inductor secondary terminals The short-circuit line of son, it is characterized in that: including shorting clip 1, plain conductor 2, cylindrical plastic set 3 and short circuit metallic column 4;
The shorting clip 1 is metal crocodile clip;
One end rises and has successively uniformly been arranged in parallel short circuit metallic column 4, and each short circuit metallic column on the plain conductor 2 4 are both provided with cylindrical plastic set 3 with 2 junction of plain conductor;
The internal diameter of the cylindrical plastic set 3 is identical as the diameter of short circuit metallic column 4;
The quantity of the short circuit metallic column 4 be 30 or more, and be located at 2 one end of plain conductor short circuit metallic column 4 with Shorting clip 1 connects.
The shorting clip 1 and 4 surface of short circuit metallic column are provided with rust preventive oil paint layer.
The copper conductor that the plain conductor 2 is 2.5 square millimeters of sectional area.
Through the above design, the utility model can be brought the following benefits: can make two by the utility model Each secondary terminals contact is good, reliable, safe when secondary winding short circuit, and test period is saved in guarantee test safety.Mutual inductor Secondary terminals short-circuit line should have the features such as reliable short-circuit secondary terminals, light-weight, durable, be able to achieve contacted with secondary terminals it is good Good, reliable, safe, the functions such as test period are saved in guarantee test safety, while plugging convenient, flexible, mode of operation multiplicity Convenient for quickly grasping.
Detailed description of the invention
The utility model is further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- shorting clip, 2- plain conductor, 3- cylindrical plastic set, 4- short circuit metallic column.
Specific embodiment
The utility model proposes a kind of short-circuit line applied to Substation Electric Equipment mutual inductor secondary terminals, features It is: including shorting clip 1, plain conductor 2, cylindrical plastic set 3 and short circuit metallic column 4;
The shorting clip 1 is metal crocodile clip, and the quantity of shorting clip 1 is more than one, needs to pacify according to Different field The shorting clip 1 for filling different number, can be used the metal device of 1 holding electrical device of shorting clip or any ground connection in use Part achievees the purpose that short circuit or ground connection;
One end rises and has successively uniformly been arranged in parallel short circuit metallic column 4, and each short circuit metallic column on the plain conductor 2 4 are both provided with cylindrical plastic set 3 with 2 junction of plain conductor;
The internal diameter of the cylindrical plastic set 3 is identical as the diameter of short circuit metallic column 4, and cylindrical plastic set 3 is set in short Road metal column 4 extracts or is inserted into short circuit metallic column 4 convenient for operator, prevents short circuit injury caused by operator, Also avoid the adverse effect to operation being likely to occur;
The quantity of the short circuit metallic column 4 be 30 or more, and be located at 2 one end of plain conductor short circuit metallic column 4 with Shorting clip 1 connects;
The short circuit metallic column 4 is hollow metal copper post, and durability is strong, and inserting mode is simply convenient for operating, same to current price The moderate sexual valence of lattice is relatively high, is suitable for mass production;
The shorting clip 1 and 4 surface of short circuit metallic column are provided with rust preventive oil paint layer, prevent in During prolonged operation because To corrode the damage for causing device;
The plain conductor 2 is 2.5 square millimeters of sectional area, and the resistivity of the copper conductor that 1 meter of length, copper conductor is low, can The stability of equipment when improving operation prevents accident or generates on the undesirable influence of experimental data.
In use, operator first feels it needs to be determined that needing to carry out the equipment of short-circuit connection, by short circuit metallic After column 4 is sequentially inserted into equipment, shorting clip 1 is clamped in the grounded metal enclosure of electrical equipment, then carries out corresponding operation.
