Insulating diaphragms belong to insulating parts. However, if the insulating diaphragms are poorly grounded or damaged, flashover and breakdown will occur. This is the partial discharge phenomenon that occurs before the insulation defects on the insulating materials break down under these insulation defects. This is a partial discharge phenomenon. In this case, We can timely understand the insulation status of high-voltage switchgear by detecting the strength of partial discharge in the insulation partition. We can accurately determine the insulation status of high-voltage switchgear by detecting discharge data online. In this case, we can promptly identify and solve the problem as soon as possible.
The power provided by high-voltage switchgear is not a low-voltage system. Firstly, we need to understand what causes the discharge phenomenon. However, in the case of discharge, what is the conductor? In the process of learning physics, we all know that water can conduct electricity except for pure water. Firstly, in China, many high-voltage switchgear environments do not belong to an absolutely dry environment, Especially in the summer, with the increase of thunderstorm weather and temperature, the humidity of the air will increase, and there will be a certain amount of water molecules inside the high-voltage switchgear. However, if the insulation partition of the high-voltage switchgear is covered with water molecules, a short circuit phenomenon will occur. This phenomenon is common, and sometimes you will find a breeding sound inside the high-voltage switchgear. Due to the high voltage, Its sensitivity will be very high.
This is determined by the environment in which the high-voltage switchgear is located. The humid environment mentioned in the appeal is one of the discharge causes of the insulation partition, and at that time, due to the temperature difference, the humidity inside the insulation partition was even higher than that caused by the outside world.
Whether outdoors or indoors, due to the lack of constant monitoring of the high-voltage switchgear, it is not ruled out that small animals have entered the high-voltage switchgear. Small animals do not necessarily have to touch the insulation partition, as discharge may also occur if they do not touch it. If small animals are between the insulation partition and the electrical components, workers must have a certain distance from the electrical components under different high voltages, So when small animals reach the effective length of the distance, electric shock may occur. One good reason is that the sealing of the high-voltage switchgear is not very complete. If animals damage the insulation partition, it can also lead to discharge.
The environment in which the insulation partition is located is crucial, and if stains appear on the insulation partition, it is also the cause of discharge. We all know that China is a major electricity user, as the increase in electricity consumption inevitably leads to an increase in transmission lines. However, if the complex connection of lines inside the high-voltage switchgear leads to a complex environment where the insulation partition is located. The increase of the circuit will result in mutual inductance, and the circuit will generate heat. However, due to the increase in temperature, small molecules in the air will undergo irregular movement. This leads to more and more stains on the insulation partition, and when added to the circuit, the insulation partition may be covered with dust. However, this phenomenon can cause the insulation partition to discharge.
The insulation partition also has a lifespan, and the temperature inside the high-voltage switchgear is not constant. Due to temperature differences, the service life of insulation partitions can be shortened. However, when designing insulation partitions, there is a certain service life, and it is possible to overlook the actual situation on site without long-term inspection or replacement.
