When, to prevent mutual inductor secondary winding from opening a way, high voltage damage electrical equipment is incuded during pressure resistance, 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 susceptible to 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 electrics, 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
Invention content
The technical problem to be solved by the present invention is to：A kind of electric operation short-circuit line is provided, GIS combined electrics, electric current are made
Short-circuit line contacts good, reliable, safety with secondary terminals when mutual inductor secondary winding short circuit, and examination is saved in guarantee test safety
Test the time.
To realize the above-mentioned technical purpose, the present invention provides a kind of applied to Substation Electric Equipment mutual inductor secondary terminals
Short-circuit line, 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 uniformly been arranged in parallel short circuit metallic column 4, and each short circuit metallic column successively 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 positioned 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 enamelled coating.
The plain conductor 2 is the copper conductor of 2.5 square millimeters of sectional area.
The short circuit metallic column 4 is hollow copper post
By above-mentioned design scheme, the present invention can bring following advantageous effect：Secondary winding can be made short through the invention
Each secondary terminals contact is good, reliable, safe when road, 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, can realize contacted with secondary terminals well, reliably,
The functions such as test period are saved in safety, guarantee test safety, while plugging convenient, flexible, and mode of operation is various convenient for quick
It grasps.
Description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated：
Fig. 1 is the structural diagram of the present invention.
