Background technology
D. C. Electric transmission earthed pole lead (DC transmission earthing electrode line) is connected on current conversion station
Circuit between DC voltage neutral point and earthing pole, it is generally called ground electrode circuit.Ground electrode circuit can use overhead transmission line, also may be used
Using cable run.Because ground electrode circuit is typically about ten to dozens of kilometres, so most engineerings use overhead transmission line.
Voltage is mainly pressure drop caused by electric current on ground electrode circuit, thus close to current conversion station end highest, close to earthing pole
Minimum, ceiling voltage typically also only has thousands of volts, by insulating requirements, can use a piece of insulator, but in view of being likely to occur null value
Insulator, typically use two panels above DC Insulator.Because ground electrode circuit dielectric strength is very low, thus it is easily subject to thunder
Hit, and afterflow is difficult to extinguish after thunderbolt, easily causes insulator and burns out and go offline.Therefore should be installed additional at insulator both ends
Arcing horn, to protect insulator.
Setting for ground electrode circuit, it is a critically important part in circuit system, but in existing technology but
It has ignored and this part is monitored in real time, it is impossible to the change of its parameter is understood well, so as to what can not be occurred in failure
When overhaul immediately.
