Characteristics of electrical tree
電樹枝的特性可歸納以下幾點(diǎn)：
The characteristics of electrical tree can be summarized in the following points:
(1) the generation of electrical trees must have a local high field strength.
(2) the electrical tree initiation is related to the intrinsic resistance of the material.
(3) the mechanical stress induced by the alternating electric field.
。
(4) the existence of air gap is the prerequisite for the generation of electrical trees.
（5）雜志的存在可誘發(fā)雜質(zhì)電樹枝。
(5) the existence of the magazine can induce the impurity electric branch.
(6) with partial discharge in the electrical tree.
(7) after the electrical tree initiation, the development is fast.
(8) the dielectric loss increases, and the insulation resistance and breakdown voltage decrease.
(9) the development of electrical tree is related to the voltage form and temperature.
Characteristics of water tree
：
The characteristics of the water branch can be summarized as follows:
(1) at the same time, there must exist both the electric field and the water, which can cause and form the water branch.
(2) with a diameter of a number of micro branches filled with micro pore space.
(3) the water branch can be produced under the electric field.
(4) water trees affected by impurities. Moisture absorption impurities and defects in insulation, voids, etc. are the starting point of water branch.
(5) the growth of the water branch is accelerated due to the increase of frequency, and it is difficult to produce the DC under or without water.
(6) there is no partial discharge in the water branch.
(7) the production or growth of water tree branches is affected by temperature.
(8) the expansion of the water branch needs longer time than the electrical branch.
(9) the water branch of the cable, the increase of the dielectric loss, insulation and breakdown voltage drop.
電化學(xué)樹枝的特性
Characteristics of electrochemical tree
電化學(xué)樹枝的特性有以下幾點(diǎn)：
Electrochemical characteristics of the branches have the following points:
(1) the evolution of the electrochemical branches is very slow, usually for a few years.
(2) branches along the electric field direction, different shape, when the branches occurred in the insulation and shielding contact defective parts, such as algae, grass or feathery; when in the internal insulation of defective parts, shaped like a bow or feather.
(3) the existence of all kinds of impurities and defects is the origin of the electrochemical branches.
。
(4) consistent with the electrochemical corrosion growth of moisture on the cable branch.
(5) there was no increase in the partial discharge of the cable with the electrochemical branches.
(6) the electrochemical branch has a color is usually brown.
(7) can occur under the much lower electric field strength.
(8) the necessary conditions are the existence of the solution of the chemical composition, such as sulfur, in the pores.
(9) the electrochemical branches generally need to be formed and the power of the branch channel and the breakdown of insulation.
