Description
技术领域technical field

背景技术Background technique
目前，加压进行电树枝引发的电极装置最常见的是对单个试样贯序进行加压测量的针板电极机构，将地电极和试样放置在二甲基硅油或者变压器油等绝缘油内，对针电极加高压，另一电极接地，在一定条件下，施加电压，观察施加电压下电树枝引发和生长。At present, the most common electrode device for pressurized electric dendrite induction is a pin-plate electrode mechanism for sequential pressurized measurement of a single sample, and the ground electrode and sample are placed in insulating oil such as simethicone oil or transformer oil. , apply high voltage to the needle electrode, ground the other electrode, apply voltage under certain conditions, and observe the initiation and growth of electric dendrites under the applied voltage.
此种方法的缺点是：第一，电树枝实验往往需要同种条件下多次实验。首先，在采取贯序进行多次实验时，由于环境温度的变化和电网波动等，完全相同的实验条件根本无法达到，因此逐次贯序进行实验大大增加了实验误差；其次，一次一个试样贯序进行若干次实验，实验时间若干倍增加，导致实验效率低下。第二，在这种实验装置下，无法获得一个对于绝缘寿命管理有着重要意义的参数，即50％电树枝起始电压。The disadvantages of this method are as follows: First, the electrical tree experiment often requires multiple experiments under the same conditions. First of all, when conducting multiple experiments sequentially, due to changes in ambient temperature and power grid fluctuations, the exact same experimental conditions cannot be achieved at all, so sequential experiments greatly increase the experimental error; secondly, one sample at a time Several experiments are performed in sequence, and the experiment time is increased several times, resulting in low experiment efficiency. Second, under this experimental setup, it is impossible to obtain a parameter of great significance for insulation life management, that is, the 50% electric tree initiation voltage.
