Description

An intelligent electroscope

technical field

The utility model relates to the technical field of high-voltage detection equipment, in particular to an electroscope.

Background technique

With the development of science and technology, we are more and more inseparable from electricity in life. The higher the voltage in power transmission, the less power is consumed. Therefore, the voltage used for long-distance power transmission is much higher than the voltage used by households, while high-voltage equipment and transmission The power distribution line needs daily maintenance or repair to ensure its normal power supply. In order to ensure the safety of maintenance personnel during maintenance, the high-voltage electroscope will be used first to test the high-voltage equipment and transmission and distribution lines to check whether there is electricity, and then the maintenance work will be carried out. The existing electroscopes can be divided according to the applicable voltage level. For: 0.4kV electroscope, 6kV electroscope, 10kV electroscope, 35kV electroscope, 66kV electroscope, 110kV electroscope, 220kV electroscope and 500kV electroscope. Its structure includes metal electrode contacts, neon lamps, a set of capacitors, ground screws, supports and isolation rings. When the metal electrode contacts approach or touch the equipment, if the neon light is on, it indicates that the equipment has high voltage.

Although the existing electroscope can accurately detect whether the equipment has high-voltage electricity, it has the following problems:

First, it is impossible to accurately locate and obtain the voltage level of the current electroscope equipment, which may cause the voltage level of the electroscope used to be inconsistent with the voltage level of the electroscope equipment. If the voltage level of the electroscope is lower than the voltage level of the electroscope, the electroscope leakage alarm may occur (the electroscope only It can effectively alarm when the equipment of the same voltage level is charged. When the voltage level of the electroscope is lower than the voltage level of the electroscope, even if the electroscope is powered, the electroscope may not alarm, causing the building to alarm) , which may cause serious misjudgment, resulting in serious accidents such as personal electric shock, live hooking of ground wires, etc.

The second is that the location of the electroscope cannot be fed back in real time, and the use information of the electroscope cannot be effectively grasped, which may cause the electroscope not to be stored in a suitable location, and then damp, affecting its insulation performance, and there is a risk of personal electric shock.

The third is that the battery of the electroscope charging module needs to be replaced. The existing batteries are mostly button batteries, which often cause battery leakage, aging, and insufficient power. The alarm signal is not issued during the power test, resulting in a leakage alarm and misjudgment of the test. There is no risk of electrical equipment being charged.

Fourth, the electroscope should be tested on live equipment of the same voltage level before the power test to confirm that the electroscope is correct and intact. Therefore, it is necessary to carry a high-voltage power frequency generator to simulate the required high voltage, and conduct a pilot test on the electroscope to ensure that the electroscope can be used. The reality is that many times the maintenance personnel often forget to carry the high-voltage power frequency generator, and the electroscope has not undergone the experimental power inspection, so there is a great safety risk. It is convenient to carry and manage, and is not conducive to the use and preservation of the power frequency generator in use.
